Q:Recently visit the building materials market to buy furniture, see a lot of style almost furniture, the price is a lot of difference, ask the sales staff is what the reasons, sales staff said that this is because the furniture used by the plate is not the same, the production of furniture made of plate than the domestic plate production Furniture, some of my puzzled, is the quality of imports of sheet metal production is really better than the quality of domestic furniture produced by the plate ok ...

Imported sheet metal produced by the following differences: 1, the import of the plate, if the election is white, the import of white than the domestic more pure; 2, the density of imported plate plate heart is higher; 3, the taste of imported plates will be smaller; 4, there is an intuitive approach, due to the high density of imported plates, so the same size of the plate than the domestic weight.

Q:PCB board what

PCB substrate classification: 1, according to the different materials (the most commonly used classification method) ? paper substrate (FR-1, FR-2, FR-3) ? Epoxy fiberglass substrate (FR-4, FR-5) ? Composite Substrate (CEM-1, CEM-3) ? HDI Sheet (RCC) ? Special substrates (metal substrates, ceramic substrates, thermoplastic substrates, etc.) 2, depending on the resin Phenolic resin plate ? epoxy board ? polyester resin board ? BT resin plate ? PI resin plate 3, according to flame retardant performance to points ? flame retardant (UL94-VO, UL94-V1) ? non-flame retardant (UL94-HB grade)

Q:What is the base plate

The base sheet is relative to the finishes. It is from the decorative materials on the practical function of the distinction, in actual use, any plate can be used as a base plate. But under normal circumstances, the construction staff will be based on a variety of plate their own characteristics and prices to choose which plate can be used for grass-roots sheet. In the decorative construction, the grass-roots sheet is like a decorative plate behind the hero, any wall, top, ground structure and shape of the deepening, are required to form a base plate to shape, shape. Therefore, the base plate is the cornerstone of decoration, is relative to the decorative plate in terms of. Generally speaking, the base plate material with low cost, strength, not easy to deformation, strong adhesion, to meet the shape and post-construction needs and other characteristics.

Q:Which plate is not easy to swell, mildew?

Simi 3D laser board, edge strip and finishes 360 ° perfect package core board, the core of the super seal protection, so that water can be non-porous, greatly improve the moisture resistance of the plate to prevent the door due to long-term in the kitchen temperature and humidity The environment of water swelling and mildew, double cabinet life.

Q:F grade sheet and EO-class plate, what is the difference between these two, Guiqiu master answer, buy a furniture to the market a question, really a headache? Which is good?

In general, if you export to Japan, you must provide F4 star certification. And E0 is our national standard (methanol content ≤ 5mg / 100g). F4 star standard is much higher than the E0 standard.

Q:Look at the Internet to say that formaldehyde harm big, how to determine the formaldehyde in the furniture sheet is not excessive? Is there any formaldehyde-free furniture?

Formaldehyde is mainly what may contain plastic, which can be used to measure the formaldehyde test tool ah, generally there will be, but the amount of the problem. The

Q:Why use office furniture

Common furniture with the plate varieties are: solid wood, fiberboard, particleboard, blockboard, plywood and so on. At present, the manufacture of office furniture is mainly used are: fiberboard and particleboard. Low-grade office furniture generally use particleboard, and medium and high-grade office furniture generally use fibreboard. Fibreboard is divided into high density fiberboard (density> 0.8 / cm3), medium density fiberboard (0.5 g / cm3 ≤ density ≤ 0.8 g / cc), low density fiberboard (density <0.5 Gram per cubic centimeter). High density fiberboard due to high density, difficult processing, and easy to nail, the installation of accessories burst; and low density fiberboard due to low density, large gap between wood fibers, easy to water swelling, resulting in surface cladding off, and even the plate disintegration, so the second The use of office furniture are less. The MDF (medium MDF), with the surface smooth, the internal structure of fine, good processing effect, with strong resistance to deformation and load-bearing capacity, And the plate holding nail ability, can be achieved many times disassembly, as in the high-end office furniture of choice. Sunlong's office furniture is used in the manufacturer's custom-made density of up to 0.76 grams per cubic centimeter of the MDF (generally medium density fiberboard density of 0.64 grams per cubic centimeter or so).

Q:How to introduce plate-type furniture plate?

Furniture: solid wood furniture and sheet metal furniture. Soft furniture and stainless steel do not say. Plate furniture are: medium density fiberboard or particleboard they are made of glue and cold pressed from. Surface paste veneer, trimethine ammonia kraft paper, brush paint. ?? To the mall to buy a furniture are generally divided into two kinds: 1 is made of medium density fiberboard .2 is made of particleboard. (Granular wood pressed from the system)
