Q:What are the types of closet panels, there are several paint-free board?

Classification of paint-free panels 1, high density paint-free board High density paint-free board price is low, it is 3mm board as the substrate, a layer of plastic mask. If you can do it yourself, you can do it yourself. 2, foam paint-free board Foam-free paint plate high price, flexibility is better, it is a thickness of about 2.5mm foam material for the substrate, a layer of mask-free film. Easy to work some, but the surface is softer, the use of finished products to be careful. 3, polymer Mianqi board Polymer Mianqi board high price, thickness of about 2 mm, its matrix and the surface is a polymer material. Made the product effect is good, high grade, but the higher cost of workmanship and materials. ? 4, other Mianqi materials Fire board, Boeing film. Fire board low price, friction, easy to clean, generally used for shoe and cabinets; Boeing film easy to use, available inside the wardrobe.

Q:With self-tapping or what ,,,, solve, six meters wide and two meters of the door can be installed on the ground in the installation of the door?

Are generally used self-tapping nails, if relatively heavy or relatively large load, you can use bolts. Aluminum-plastic composite board is a chemically treated coated aluminum sheet for the surface material, with polyethylene plastic as the core material, in the special aluminum-plastic plate production equipment from the processing of composite materials. The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building facades, curtain wall panels, retrofits of old buildings, interior walls and ceilings, advertising signs, display stands, engineering. Belonging to a new type of building decoration materials.

Q:How much does the ring do the ring?

Q:What is love board?

AIG is the Austrian Group of Agrites FRITZ EGGER GMBH Co. is located in 17 factories in Europe, the production of man-made sheet, environmental protection level to the European E1 level. The Aige plate substrate is covered with a layer of special dipping treatment, with anti-characterization, acid and alkali surface, is widely used in plate furniture and kitchen furniture, English referred to as MFC. ??????? The love plate is selected from coniferous trees grown in the continental margin of the European continent. The love grid overcomes the shortcomings of natural wood and has physical properties that are not easily deformed and stable. Ai grid is a kind of natural logs by cutting, crushing, high temperature and pressure made of a more suitable for furniture production and use of the plate.

Q:How much profit margins of decoration materials

Tiles profit is relatively large, see what you take the route, the brand profit the largest, the smallest profit transfer, wood floor is the same

Q:Stainless steel wire drawing board, polishing plate, mirror the difference between the three

The drawing board is the original surface (matte surface or industry called 2B face) through the conveyor belt into the belt with high-speed operation to produce friction, the effect of its surface; polishing plate is a linen wheel and polished polished surface Effect, the industry or called 6K board; mirror plate is iron red powder, nitric acid, water as a grinding medium to wool felt grinding surface, the effect can be compared with people with the mirror. The surface of the polishing plate is brighter, the surface has the image effect, but the relative blur, the image deformation; the mirror surface is bright as the mirror, the mirror surface is bright, the surface of the mirror surface is bright, Image is clear.

Q:What is the difference between acrylic and resin plates?

Acrylic is the polymerization of PMMA produced by the polymerization of PMMA commonly known as polymethyl methacrylate, the use of pouring process, the domestic acrylic flat plate tolerance is relatively large, so if the design of the sandwich, the thickness must be more than 8MM, the plate is easy to deformation;
