In the field of construction engineering, material innovation has always been an important driving force for the progress of the industry. PVC Corner Bead is a high-performance composite material based on glass fiber. With its unique structural design, excellent physical and chemical properties and wide applicability, it is gradually becoming an indispensable functional material for modern architecture. The inside corner bead adopts a warp and weft bidirectional weaving process to form a regular rectangular or diamond mesh structure. This structural design has the following significant advantages: 1. Stress dispersion mechanism: The cross weaving at the mesh node forms a mechanical fulcrum. When the material is subjected to external loads, the stress can be evenly diffused to the surroundings through the mesh, effectively avoiding material failure caused by local stress concentration. Experimental data show that the elongation at break of standard corner bead can be controlled within 3% in the tensile test, which is much better than the 10% or more of ordinary materials. 2. Deformation coordination ability: The mesh structure gives the material good flexibility and can adapt to the subtle deformation of the building base. In the temperature cycle test, the interface shear strength between the drywall corner bead and cement mortar can reach 0.8MPa, ensuring stable bonding performance under extreme temperature difference environments.

PVC Corner Bead, also known as fiberglass geotextile, is a geosynthetic used in civil engineering projects. It is primarily composed of a composite of glass fiber and staple-staple needle-punched nonwoven fabric.

If possible, ask the supplier to provide samples and compare them with other brands or batches of products to evaluate whether their quality is consistent. In short, judging whether the quality of the PVC Corner Protectors meets the standard requires comprehensive consideration of multiple aspects. When purchasing, you should choose a reputable supplier and conduct a comprehensive quality assessment.

The Drywall Corner bead plays a very large structural role in the insulation system during construction. It is mainly to prevent the occurrence of cracks. The Protection Bead Pvc will not be easily damaged when it is hit, unless it is a serious matter. However, the Drywall Corner bead is not only impact-resistant but also easy to construct. Although the Protection Bead Pvc polyurethane rigid foam insulation layer itself has good anti-aging ability, it will also accelerate the aging of polyurethane foam materials in harsh environments such as long-term sudden cooling and heating. Therefore, improving the environment in which the polyurethane rigid foam insulation layer material is located, such as reducing ultraviolet radiation, reducing water vapor, chemical erosion, moderate temperature and humidity, avoiding long-term sudden cooling and heating or long-term exposure to cold and hot environments, slowing down its aging and extending its service life, Plastic Bead Guards is also very necessary for exterior wall insulation. ZL glue powder polystyrene particle insulation slurry contains a large amount of inorganic materials, and its aging performance is superior to that of polyurethane rigid foam organic materials. Using ZL glue powder polystyrene particle insulation slurry, a 1.5~2.0cm thick leveling treatment is made on the surface of the polyurethane rigid foam insulation layer, which has the following protective and anti-aging effects on the polyurethane insulation layer: a. The 1.5~2.0cm thick glue powder polystyrene particle leveling layer, coupled with the aging resistance of the anti-cracking layer and bead corner drywall finishing layer materials, can effectively prevent ultraviolet rays from damaging the insulation layer.

PVC Corner Bead is a specialized engineering plastic expansion screw used to secure insulation panels to walls. inside corner bead is a specialized anchor for exterior wall insulation, used in building decoration and for anchoring insulated walls. It consists of galvanized screws, nylon expansion tubes, and retaining discs. It comes in various sizes depending on the thickness of the insulation layer. PVC Corner Bead consists of three parts: a nylon sleeve; a galvanized steel screw inside the sleeve; and a nylon disc at the front of the sleeve (used to press against the insulation panel). Its length varies depending on the thickness of the insulation panel. It is used for anchoring insulated walls in building decoration. It offers excellent resistance to temperature fluctuations, corrosion resistance, cold and heat resistance, high load-bearing capacity, high pressure resistance, and excellent tensile strength. It resists deformation under load, is moisture-resistant, dampens vibration, and provides excellent thermal insulation. Installation is simple, requiring no special tools. Galvanized screws solve the corrosion problem very well and have good durability. The nylon material has low heat transfer performance and there is no cold bridge in winter. According to the wall material and the anchored exterior wall material, it can be roughly divided into solid wall PVC Corner Bead and hollow brick corner bead. The drywall corner bead on the market is basically integrated and easy to use.

If Drywall Corner bead is used throughout the house, it is usually laid before puttying. If 50x50 plastic angle is not installed, the wall is more likely to crack; especially after living in the house for a long time, l shaped pvc edging can enhance the durability of the wall and reduce the chance of cracking. In the case of a very low decoration budget, some places are recommended: ① Joints of different materials; ② Position of grooves; ③ Renovation of old houses; ④ Positions of cracks; ⑤ New walls. In fact, the price of pvc internal corner materials is very low, only a few cents to a few yuan per square meter; but the labor cost is slightly more expensive, which may be 10-20 yuan/square meter; for the decoration package to the decoration company, here the designer sister gives a money-saving trick, which is to buy the materials yourself and pay the workers to do it directly!

When choosing the thickness of PVC Corner Bead, the consideration of alkali resistance needs to be combined with its material characteristics and application scenarios. The core logic is: the combination of thickness and alkali-resistant coating determines the life and performance stability of render bead in alkaline environment. It can be analyzed from the following perspectives: It is the base material of render bead, and its own alkali resistance determines the anti-aging ability of drywall corner beads. Alkali-free fiber (alkali metal oxide content ≤ 0.8%) has better alkali resistance than medium alkali fiber (content about 12%). Therefore, at the same thickness, drywall corner beads made of alkali-free material is more suitable for scenes in alkaline environment for a long time (such as cement mortar base). The anti-alkali emulsion (such as acrylic coating) coated on the surface is the key to alkali protection. The uniformity, thickness and bonding strength of the coating with the fiber directly affect the ability of internal corner tape to resist erosion by cement hydration products (strong alkalinity).

When making polymer mortar, a dedicated person is required to ensure proper mixing quality. Open the bucket lid counterclockwise and remix the binder with a mixer or other tool to prevent separation of the binder. Proper mixing will prevent quality issues. Cut the material in a clean, flat area. Cut the material as needed. The cut PVC Corner Bead must be rolled up and not folded or stepped on. A reinforcement layer should be applied to the inside of the building's exterior corners, 150mm per side. When applying the polymer mortar, ensure the EPS board is dry and remove any harmful substances or impurities. At the four corners of doors and windows, after applying the standard inside corner bead, add a 200mm x 300mm standard corner bead at a 90-degree angle to the bisector of the window corner. This should be attached to the outside for reinforcement. At the interior corners, add a 200mm long Inside corner bead piece, the width of which corresponds to the window width. Below the first-floor windowsill, to prevent damage from impact, install reinforced corner bead before standard PVC Corner Bead. The reinforced drywall corner bead should be butted together. The protective layer should not be exposed to rain for four hours after construction. After the protective layer has finally set, spray it with water for maintenance for at least 48 hours if the average night temperature is above 15°C, and for at least 72 hours if it is below 15°C.

High strength and high modulus: Develop glass fiber raw materials and production processes with higher strength and modulus, so that PVC Corner Bead can withstand greater external forces and loads in the fields of construction, aerospace, etc. High weather resistance: By improving the formula and surface treatment technology, the ability of corner bead to resist the influence of environmental factors such as ultraviolet rays, humidity, and temperature changes is improved, and the service life of the product is extended. Green production process: Research and develop and adopt low-pollution and low-energy production processes, such as new kiln technology and waste heat recovery, to reduce energy consumption and pollutant emissions in the production process. Exploration of degradable materials: Research on the use of bio-based degradable materials to prepare inside corner bead, or develop recyclable and reusable products to reduce the burden on the environment.

Nowadays, no matter what type of product people buy, they hope to choose a cost-effective one. In this way, there is a greater guarantee in terms of use effect and use cost. The same is true when choosing Drywall Corner bead. You should know that there are many sales of this type of plastic angle bead in the market. There are certain differences in the selling price and use effect of the 10mm plastic angle produced by different manufacturers. Therefore, if you want to choose a cost-effective plastic angle bead, you can start from these aspects. Choose a manufacturer with a good market reputation. There are many manufacturers engaged in the production and sale of 10mm plastic angle. Different manufacturers mean that there are differences in many aspects of the product. When choosing, people can try to choose manufacturers with relatively good market reputation, because this type of manufacturer has accumulated good evaluations and various aspects in the process of operation. Especially in terms of product quality, it is even better. After all, only those who have used the products produced by them can give corresponding evaluations. Compare and understand the quality level. If the same product has different quality levels, in addition to different sales conditions in the market, there are also differences in various aspects such as use effect. Before buying Drywall Corner bead, people should have a proper understanding of the 40mm plastic angle materials in the market, especially in terms of quality level. In this way, you can choose a better 40mm plastic angle material. So people need to pay attention to these aspects when choosing Drywall Corner bead, because it is directly related to the cost performance of the material. If there are advantages in these aspects, then its cost performance will be guaranteed.

Drywall Corner bead is usually used in the external wall insulation system, which will not produce "thermal bridges and cold bridges" and has excellent building energy-saving and insulation effects, so it is highly praised by the construction industry. In winter, when the indoor heat passes through the pvc square beading insulation material, it will be cut off and retained, and when the indoor temperature drops. The heat in the wall will be released to adjust the indoor temperature. In summer, the pvc square beading insulation will prevent the radiation of the sun and the external heat from entering the room, so that the indoor environment of the building is "warm in winter and cool in summer", pleasant in all seasons, and the physical and mental properties of the residence are significantly improved. At the same time, the plaster protection can also protect the main structure. The external wall insulation material is placed outside the main structure, which relaxes the external temperature, humidity, and various rays from infecting the main structure. Under the multiple effects of high temperature in summer and low temperature in winter. The main body of the building often expands and contracts due to heat and contracts, causing cracks. It reduces the service life, but the drywall tape paper can minimize this adverse effect. The drywall tape paper is placed outside the main structure during use, thus saving indoor space and effectively increasing the indoor usable area.

①Film wrapping: Polyethylene (PE) film is usually used to tightly wrap the PVC Corner Bead. This layer of film can effectively prevent moisture and dust, and protect the PVC Corner Bead from erosion by the external environment. For conventional roll inside corner bead, it is wound in a spiral manner starting from one end of the reel. The thickness of the film is generally 0.05-0.1 mm to ensure that the PVC Corner Bead is completely covered. ②Plastic bagging: For sheet inside corner bead, plastic ziplock bags or open bags of suitable size can be used for packaging. Put the PVC Corner Bead flat into the bag, squeeze out the air and seal it. Ziplock bags are easy to take, and open bags are suitable for larger sheet products. After loading, the bag mouth can be tied with tape or rope. 2. Outer packaging ①Corrugated carton: After the roll or sheet corner bead is packed, it is placed in a corrugated carton. The compressive strength of the carton should be sufficient. According to the weight and size of the corner bead, choose the appropriate number of layers of corrugated paper. Generally, three-layer or five-layer corrugated carton is more commonly used. Product specifications, models, quantities and other information are printed on the outside of the carton for easy identification and management. ② Woven bag packaging: For some transportation scenarios with large quantities and relatively low protection requirements, plastic woven bags can be used for packaging. Put multiple rolls or pieces of drywall corner bead into the woven bag and seal it with sewing thread. The woven bag has certain wear resistance and moisture resistance, which can meet the needs of short-distance transportation and temporary storage. 3. Special protection ① Buffering material: If the product needs to be transported over long distances or has high requirements for shockproof, buffering material can be added to the packaging. For example, foam boards, bubble pads, etc. are placed around the carton to prevent the PVC Corner Bead from being damaged due to collision and vibration during transportation. ② Desiccant placement: For further moisture-proofing, place an appropriate amount of desiccant in the package. Common silica gel desiccant is packaged in a breathable small bag and placed inside the drywall corner bead package to absorb moisture that may enter.

The main raw material is PVC Corner Bead, and its price fluctuation has a direct impact on the production cost of inside corner bead. The price of inside corner bead is subject to many factors, including glass raw material prices, energy costs, market supply and demand, etc. In recent years, with the adjustment of glass industry production capacity and fluctuations in energy prices, the price of corner bead has fluctuated to a certain extent. When the price of corner bead rises, the cost pressure of drywall corner bead production enterprises increases, and some enterprises will pass on the cost by raising product prices, which may have a certain inhibitory effect on market demand. When the price of drywall corner bead falls, the cost advantage of enterprises is reflected, and market competition may become more intense. Enterprises may compete for market share by reducing prices, further compressing profit margins.

There is a special knowledge collection for Drywall Corner bead to prevent cracking of external wall insulation system: Corner Beads Angle plays a role of stress dispersion in the external wall insulation system, and together with the coating mortar, it forms the protective surface of the external wall insulation system, which can resist surface cracking caused by natural temperature and humidity changes and accidental impact. External wall insulation Corner Beads Angle is made of alkali-resistant or medium-alkali glass fiber yarn as raw material, woven into Beads Angle Casing as base material, and then coated with acrylic copolymer liquid and dried to form a new type of alkali-resistant product. Beads Angle Casing manufacturer wall reinforcement material. Due to the special material properties of Drywall Corner bead, it is stronger and more durable than ordinary cloth because it has high strength and good alkali resistance. The performance of Beads Angle Render and its compatibility with surface glue are important factors in determining whether the quality of external insulation system is cracked. Breaking strength and alkali resistance retention rate, breaking strength and alkali resistance retention rate are important performance indicators of Beads Angle Render. Breaking strength is closely related to the number or weight of glass branches. At present, the weight of Drywall Corner bead used in external wall insulation system is about 130g per square meter, and its strength is generally low, with normal breaking strength of only about 1000n/5cm. In countries such as Europe and the United States where external insulation technology and regulations are relatively mature, the breaking strength requirements of Drywall Corner bead are much higher than those in my country. The German Building Technology Committee (DIBT) stipulates that the normal breaking resistance of Drywall Corner bead used in external wall insulation system is 1750n/5cm, and the alkali resistance retention rate is 50%.

Cut it in a clean and flat place, the cutting must be accurate, and the cut PVC Corner Bead must be rolled up, folding and trampling are not allowed. Make a reinforcement layer at the positive corner of the building, and the inside corner bead manufacturer's reinforcement layer should be attached to the innermost side, 150mm on each side. When applying the first coat of polymer mortar, the EPS board surface should be kept dry, and harmful substances or impurities in the board cotton should be removed. At the four corners of the door and window, after the standard net is applied, a 200mmx300mm standard net is added to the four corners of the door and window, placed at a 90-degree angle to the bisector of the window angle, and attached to the outermost side for reinforcement; a 200mm long inside corner bead with a width suitable for the window width is added to the negative corner, and attached to the outermost side. Below the first window sill, in order to avoid damage caused by impact, the reinforced corner bead should be installed first, and then the standard corner bead. The reinforced drywall corner bead should be connected. The protective layer cannot be exposed to rain within 4 hours after construction. After the protective layer has finally set, it should be sprayed with water for maintenance in time. When the average night temperature is higher than 15℃, it should not be less than 48 hours, and when it is lower than 15℃, it should not be less than 72 hours.

Since the opening of the door to science and technology in the new era, our cities are full of tall buildings rising from the ground. Only in the old city or rural areas can we see old houses with a long history. But even old houses need to be lived in, so they are renovated, the original exterior and interior walls are scraped off, and wall Drywall Corner bead is added. Next, I want to know more about the application and construction methods of drywall corner edge on old walls. To paste the drywall corner edge, it depends on whether the wall structure has cracks. If not, it is not necessary to paste it all, just hang some in the joints or grooves where it is easy to crack. First, the wall base needs to be cleaned, and white latex is applied to the position where the plasterboard edging needs to be pasted with a roller brush, and it is evenly applied. Then spread the plasterboard edging, cut it to the appropriate size, and spread it flat on the position where the white latex is applied. After the corner bead corners is pasted, adjust the appropriate position, and then evenly apply a layer of white latex on the Drywall Corner bead again to make it stick firmly. After hanging the Drywall Corner bead on the wall, start plastering. Generally speaking, wall corner bead corners is needed for lightweight walls, lightweight partition walls, thermal insulation walls, joints between new and old walls, and after water and electricity grooving. Drywall Corner bead is used on cement, gypsum and walls to increase strength and prevent cracking.
