The whole cabinet purchase does not fall into the wrong zone
Consumers often go into some misunderstandings when buying cabinets, because they are not experts in this industry themselves, and some customary material names and misunderstandings caused by literal meaning in the market often bring unnecessary unnecessary to the kitchen. Trouble, even causing a certain degree of harm. Therefore, when purchasing the whole cabinet, you must think more about the materials of some sensitive words, and don't go into the wrong area.
Fire board, can it really be fireproof?
From the literal point of view, it is easy for consumers to conclude that the fire board is fireproof. In fact, there is no real fire protection for any material. This material is only a certain degree of fire resistance, not really fireproof. Therefore, the name of the fire board is not rigorous, the correct name should be "fireproof board." It should be noted that the refractory board should be marked with time resistance to open flames. In the fire-resistance time standard, the open flame barbecue can only produce black soot that can be wiped off without chemical reaction.
Moisture proof and waterproof can't be equated
A large number of people believe that moisture and water resistance can be equated. This concept can easily mislead consumers during use, causing cabinets to be eroded by water. The moisture resistance of the board is produced by infiltrating the moisture barrier agent into the sheet substrate. The moisture-proofing agent is colorless, and the manufacturer adds a green or red pigment as a recognition mark in order to distinguish it from the ordinary plate. It is important to note that the moisture-proofing agent does not have any effect on the waterproof performance of the board itself. It has been proved that the board with the moisture-proofing agent and the board without the moisture-proofing agent are immersed in water, and the expansion ratio is the same. The so-called moisture-proof means that it is against the air. The moisture in the middle has an isolation effect. Therefore, do not let the cabinets soak in water.
The formaldehyde standard should be carefully observed
The regulations of the People's Republic of China on formaldehyde in wood-based panels are that the dry plate is less than or equal to 9 mg/100 g, that is, up to 9 mg of free formaldehyde is allowed in 100 g of dry plate. The surface is stricter, but there is another standard in the country, namely, the wood-based panel. After surface treatment, the formaldehyde content is allowed to be 30 mg, which is very protective for small-scale manufacturers. Therefore, when purchasing cabinets, the amount of formaldehyde released is an important indicator. The cabinet is at least 1/3 of the size of the kitchen, and its main raw material is wood-based panels. If the material is not up to standard, there will be pollution, plus the open fire in the kitchen, the high temperature will accelerate the evaporation of harmful substances. Try to minimize on-site edge sealing. Because it is difficult to seal on site, the factory uses high temperature and high pressure edge sealing, and it is firm and tidy after sealing. In some places, if you need to seal the edge on site, you should also use good quality glass glue or transparent glue, which has good waterproof effect. Some of the more regular cabinets use white box materials, which contain a green moisture-proof agent, and all the holes on the box are covered with caps to prevent moisture from entering and reduce formaldehyde release.
Identify whether artificial stone countertops are safe and environmentally friendly
Many consumers like to use artificial stone as the countertop of the cabinet. Because there is radioactive material in the granite, it is heavy and difficult to cut. However, some synthetic synthetic stone uses benzene and volatile organic compounds. Therefore, when selecting the whole countertop, be sure to smell a strong irritating smell and see if all the edges are covered. deal with.
FR4 is not a material`s name, but a kind of grade of fire-resistant, which represents resin materials can self-extinguish when firing. Now there are all kinds of FR4 materials using as PCB, but the majorities are composite made of epoxy resin, filler and fiberglass.
G10 FR4 Sheet mainly used as insulation structure parts in electrical, electronic and other industries.
Key Features :
• Flame resistance
• High dielectric strength
• Moisture resistance
• Heat resistant
• Temperature resistance: 180-200℃
• Under the normal temperature 150 ℃, it still has high mechanical strength.
