In recent years, PVC sheet buckle ceilings are light, corrosion resistant, anti-aging, M-heating, and good insulation. Insulation moisture, fireproofing and fire prevention and other characteristics, a wide range of applications in the kitchen, bathroom ceiling decoration c With the growing variety, printing, film and hot stamping and other surface decoration technology promotion and application of the board surface quality continued to change , The decorative nature has been greatly enhanced. This is why the plastic PVC sheet gussets have entered every family and created good conditions. However, at present, the market for plastic PVC sheet gussets in 丨8| is uneven, and the pros and cons are hard to distinguish. Subsequent shuffling and continuous disposal of poor quality PVC sheet gussets to the market = The use of plastic PVC sheet gussets mainly involves kitchens, II rooms and balconies. These areas are not only in poor environmental conditions, but also require more plastic PVC sheet buckles. The board is not only waterproof, but II must be attached with temperature changes. To facilitate the majority of the f? Material PVC plate buckle plate users, here specifically introduces the material PVC plate buckle plate identification method. (1) The industry standard (QB/T12133-95) stipulates that the wall thickness of the PVC plate gussets should not be less than 0.7 奄m, especially the decorative surface. Manufacturers' products must meet this requirement. Some manufacturers reduce the cost and reduce the use of materials, and use r to reduce the wall sequence. When purchasing, the user only uses the lower profile thicker, ie, SL. (2) Observe the roughness of the saw a and the inner surface of the board. Good quality PVC plate gussets have good strength and toughness. When the board surface and inner ribs are sawn, they will not collapse. A sawn flush, no burrs, cracks and other phenomena. The inner surface of the curve and the inner ribs are smooth and there are no obvious bubbles. However, poor quality PVC plate buckle saw n will appear burrs, the inner ribs and the top and bottom of the board is prone to collapse u, cracks, and the inner surface is rough, more bubbles on the inner ribs; (3) Take a piece of PVC sheet. With both hands, hold the bow and bend in the vertical direction. If it is a poor quality sheet, it is easy to break and crack. However, a high quality sheet will not have such a situation. Even if the water is deformed for a long time, it will break or crack. This is the simplest and most effective way to check the intrinsic quality of the PVC sheet gussets. The main raw material for the production of plastic PVC sheet gussets is poly ethylene, which reduces the shrinkage of the PVC sheet gussets and prevents warpage when extruded into PVC gussets. rigidity. However, some manufacturers are now seeking high profits in order to reduce costs. The proportion of calcium carbonate is greatly increased, and a large amount of plasticizers are used, resulting in a thin and brittle plate. When installed and used, it cannot bear the necessary pressure and impact, and it is easy to lose color and luster, and easy to age. (4) Use a nail to draw the printed surface. There is a layer of light film on the printed pattern of the printed PVC sheet. From the role of the protective pattern and pattern, the film must have a certain hardness in order to wear. To check the hardness of the film, you can use your fingernail on the surface of the film to check back and forth to see if any scratches will be left. In general, high-quality PVC plate gussets will not leave scratches. If scratches appear, it means that the lacquer film used to protect printing fields has poor hardness and is easily scratched during use. (5) Glue the adhesive tape along the length direction of the PVC plate and evenly affix it to the surface of the PVC plate pinch. Do not leave bubbles in the plate and adhesive tape. Paste the length of 0.5 cm or so, and then quickly tear the tape along the surface of the board. If the glaze is not peeled off, it means that the surface of the PVC board buckle film has good adhesion, and the use of printing patterns to protect the effect; otherwise, it shows The adhesion of the optical layer on the surface of the PVC plate pinch is poor, and the surface light film is easily peeled off when used.
