PVC Edge Strip Related Knowledge Points

PVC is made of polyvinyl chloride, which is mixed and rolled by adding appropriate amounts of anti-aging agents, stabilizers, calcium carbonate, CPE, dyes, epoxidized soybean oil, modifiers, etc. PVC is divided into software PVC and hardware PVC. PVC edge strips are divided into plain PVC stickers and wood grain PVC edge strips according to their colors. Plain color refers to a single color, such as red, yellow, blue, green, etc. The upper layer is made of PVC, and the lower layer is colored with primer. The general colors are different.

Let’s learn about the key points of knowledge about PVC edge banding strips!

1. Benefits

A: The edge of PVC edge banding strip is very light, which is compared with metal and plexiglass. The lightness of PVC seals is not due to polymer compounds, but because it is composed of organic compounds, that is, light elements such as carbon, hydrogen, oxygen, and nitrogen.

B: The edge material of PVC edge banding furniture is plastic, and plastic is easy to process. Plastic is malleable. In other words, it deforms after being heated or pressurized, and maintains its original shape even after the temperature drops or the pressure disappears. Through extrusion and other methods, it can be processed into T-shaped borders, H-shaped borders, D-shaped borders, V-shaped borders, character-shaped borders, and other shapes.

2. Detection Method

Visually confirm whether the color and texture of the sealing tape and the board used are consistent, or whether they are consistent with the designer's requirements.

Check whether the surface of the sealing tape is smooth and flat, and whether there are any spots. If there are spots or pinhole-like hairs, it may be made from recycled hybrid PVC.

Check whether the back of the seal is flat. You can make sure it's straight by hanging the seal sideways with a flat blade. Otherwise, thick rubber lines will appear on both sides after sealing.

If the back of the sealing tape is flat, thick rubber lines will appear after sealing. You can check it with the following method. Check whether the saw surface of the board is flat and whether the specifications of the upper and lower saw blades are the same. If they are different, there will be small steps on the saw blade surface, which will affect the edge sealing.

3. Features

PVC edge banding is a thermoplastic roll made of polyvinyl chloride as the main raw material, adding plasticizers, stabilizers, lubricants, dyes and other additives, and mixing and pressing them together. Its surface has patterns such as wood grain, marble, and cloth grain. At the same time, the surface has a soft luster, has the authenticity and three-dimensionality of wood, has a certain gloss and decoration, and has certain heat resistance, chemical resistance, and corrosion resistance. , the surface has a certain hardness. The main function of the seal is to fix the cross-section of the board, prevent damage to the board by environmental and unfavorable factors during use (mainly moisture), prevent the volatilization of formaldehyde inside the board, and at the same time achieve a decorative effect.

4. Judge Good or Bad

A: From the perspective of the hue and surface roughness of the frame, the color of a good frame surface is also very important. For example, whether the color is close to the customized product and whether it is bright. If the surface is rough and there are pull marks, then the quality is definitely not up to par. This is a matter of seal surface quality. It has little to do with the quality of the inner material of the edge banding strip. It mainly depends on the production technology of the edge banding strip factory and the production technology skills of the employees. A good edge should have a smooth surface with no or little blistering. Unattractive or less attractive. The gloss is moderate, not too shiny or matte. Unless there is a special request.

B: Check the flatness of the surface and bottom of the seal, and whether the thickness is uniform. If the joint between the seal and the plate and the rubber line are too protruding, the gap between the plate and the seal will also affect the overall appearance. Details determine success or failure, and it is often small details that may lead to embarrassing situations where the overall effect is not achieved.
