The installation of the whole wardrobe is a complicated project. If the base material of the wardrobe is selected, various problems will arise during the subsequent operation. The plate edge is also an important work, how to assess the effectiveness of the plate edge? We need to see whether the edge is smooth, smooth, tight seams, whether the edge is significant, the corner is delicate.
| A simple classification of edge sealing materials |
(1) veneer veneer, natural wood appearance. Disadvantages: Easy to fade paint, veneer easy to crack.
(2) PVC film has many shapes, rich colors, good abrasion resistance, good flexibility, no cracking, no fading, and is a common material for Hai Nei Niu furniture.
(3) PVE film cost is high.
| Second, how to assess the effect of plate sealing |
See if the seal is smooth and smooth, if the seams are tight, if the edges are prominent, and if the corners are delicate.
| Third, the edge of the material introduced |
1. When buying a wardrobe, you must check whether the seal is even and whether it is warped or cracked. Good solid wood furniture, when combined, must be tight. Generally veneer veneer, looks beautiful, made of imitation wood grain, simple process, high temperature, not easy to wear, low cost. If the wood is used to treat the surface, it looks like solid wood furniture. The wood-based panel is also good, not easily deformed, cracked, and low in cost.
2, PVC edge wardrobe is also more, rich colors, with good abrasion resistance, good flexibility, no cracking, no fading, we all know that the general wardrobe of the plate with three parts, the innermost plate is generally in Density fiberboard or chipboard, this looks ugly if it is not sealed.
3, there is a material is made of international advanced material ABS resin ABS edge banding, this edge banding is easy to use but expensive, so few people know.
| Fourth, the edge of the maintenance |
1. When the edge band of the wardrobe is stained with dust, it should be wiped with a soft towel. If it is a stain that is difficult to remove, it can be removed by sandblasting.
2, wardrobe to avoid direct sunlight, so as to avoid oxidation of the surface paint film, color difference.
3, usually pay attention to maintenance, regular finishing of the wardrobe, avoid using a sharp object to scratch the edge strip.
| Fifth, sealing and formaldehyde |
Why do you say that the edge banding is not good and will affect the release of formaldehyde? Because the edge band itself can inhibit the release of formaldehyde, the market has a separate sale of the edge band, many people are not very understanding, leading to a lot of closet edge failure phenomenon. A good edge strip can reduce formaldehyde emissions.
Summary: After reading so much information about the material of the wardrobe edge, we also have a certain understanding of the wardrobe sealing and effect assessment. If you want to see other aspects of knowledge, you can log on this site information channel, more exciting content wait for you.

15-25mm Calcium Carbide: Physical and chemical properties: ores are solid brown or black block, pure white crystals (including CaC2 higher purple). Density of 2.22 g / cubic centimeter, the melting point of 2300 ° C (with CaC2 content), water immediately intense reaction to generate acetylene, and release heat, Calcium Carbide content varies with the melting point also will change.
Impurities: Caustic soda often contain calcium arsenide (Ca3As2), calcium phosphide (Ca3P2) and other impurities, and the role of water at the same time release arsine (AsH3), phosphine (PH3) and other toxic gases, so the use of Acetylene generated by calcium carbide is toxic.
Crystal structure
The most common crystal form of CaC2 is tetragonal, stable between 298K and 720K. Quartet CaC2 similar to the crystal structure of NaCl, but due to [: C≡C:] 2- ion oval, oriented, the crystal is tetragonal. In CaC2 crystal, the C-C distance is 120pm, which corresponds to the bond length of carbon-carbon triple bond, the distance between Ca and C is 259 and 282pm.
