Key points of knowledge related to PVC edge banding

PVC, the main component of which is polyvinyl chloride, is made of polyvinyl chloride resin as the main raw material, an appropriate amount of anti-aging agent, stabilizer, calcium carbonate, CPE, dye, epoxy soybean oil, modifier, etc., mixing, rolling, etc. It is divided into software PVC and hardware PVC. According to its color, PVC edge banding strips can be divided into plain PVC stickers, wood grain PVC edge banding strips. Plain colors refer to the red, yellow, blue, green, etc. that often live, which can also be said to be plain colors. That is to say, it means a single color, with the upper layer made of PVC material and the lower layer made of primer. It is relatively easy to use plain edge boards first, but white boards use white edge sticks. The same goes for the following. There are differences in general colors, let's learn about the key knowledge points related to PVC edge banding together!

1. Benefits

1、 The edge of PVC sealing strips is very light. This is for metal and organic glass. The reason for lightness is not due to polymer compounds, but rather composed of organic compounds, such as carbon, hydrogen, oxygen, nitrogen, and other light elements.

2、 The edge material of PVC edge banding furniture is plastic, which is easy to process. Plastic has plasticity. That is to say, after heating or pressurization, deformation occurs, and the temperature drops or the pressure disappears, maintaining its original shape. By pressing and other methods, it can be processed into T-shaped borders, H-shaped borders, D-shaped borders, V-shaped borders, and font shapes.

2. Detection method

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

Check whether the surface of the sealing tape is smooth and flat, and whether there are any impurities. If there are spots or fine needle like hairs, it is possible that they are made from recycled hybrid PVC.

Check if the back of the seal is flat: You can use a flat blade to hang the seal horizontally and confirm if it is in a straight line. Otherwise, thick rubber lines will appear on both sides after sealing.

If the back of the sealing tape is flat and thick rubber lines appear after sealing, the following methods can be used for inspection. Check if the saw surface of the board is flat. In the case of saw blades, if the specifications of the upper and lower saw blades are different, there will be small steps on the saw blade surface, which will affect the edge sealing.

3. Characteristics

PVC edge banding is a thermoplastic roll material made by mixing and pressing PVC as the main raw material, adding plasticizers, stabilizers, lubricants, dyes and other additives. Its surface has patterns and patterns such as wood grain, marble, and cloth grain, while its surface luster is soft, with a certain glossiness and decorative properties of wood authenticity and three-dimensional sense. It has a certain degree of heat resistance, drug resistance, corrosion resistance, and surface hardness. The main function of sealing is to fix the cross-section of the board, prevent environmental and adverse factors (mainly moisture) from damaging the board, prevent the volatilization of formaldehyde inside the board, and achieve decorative effects.

4. Judging good or bad

1. From the perspective of the color scheme and surface roughness of the border, the color of the good border surface is also important, whether the color is close to the customized product and whether it is bright. If the surface is rough and has pull marks, then quality is definitely everywhere. This is the issue of surface quality of seals. It is not closely related to the quality of the internal material of the edge banding strip, but mainly the production technology of the edge banding factory and the production technical skills of the employees. A good edge should have a smooth surface without bubbles or less bubbles. Lack of attraction or lack of attraction. Moderate gloss, not too bright or matte. Unless there are special requirements.

2. Check the flatness of the surface and bottom of the sealing element, and whether the thickness is even. Otherwise, the joint between the sealing element and the sheet metal, as well as the rubber line, is too prominent, and the gap between the sheet metal and the sealing element affects the overall aesthetics. Details determine success or failure, often small details that may lead to awkward situations where the overall effect cannot be achieved.
