Q:How to identify solid wood and sheet metal
First of all, you can distinguish from the pattern, pure solid wood furniture pattern is no change in the law, and paste leather furniture pattern changes are very regular, such as butterfly-like, or words continue to head, and pure solid wood furniture patterns are irregular The second measure is that you can look at the furniture is not used to start the falcons, falcons are solid wood furniture, one of the necessary technology, the so-called falcon, that is, slot, wood and wood convergence is not glue and nails , But rather like a child to play the same building blocks, so that together, this is why the reasons for environmental protection of solid wood furniture, and the layout of the furniture is absolutely impossible to use frying craft third trick, generally better solid wood furniture, in addition to In addition to the structure of the falcon, there should be splicing technology, splicing is divided into two kinds, tooth and then flat, as the name suggests, tooth connection, is the two selected wood, both ends are playing like a tooth-like teeth, and then two pairs Together, this is the tooth connection, if there are teeth of the furniture, take the wardrobe door, the door inside and outside the tooth interface must be on the fourth move, solid wood furniture should generally be round circle The design of the corner, because only the wood, in order to withstand the pressure to cut into a circular, the layout is not possible
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:Now on the market E0 grade plate how?
According to the European environmental standards, the wood products in accordance with the release of formaldehyde content, divided into three levels, namely E0 level (formaldehyde emission ≤ 0.5mg / L), E1 level (formaldehyde release 0.5mg / I ~ 1.5mg / L), E2 level (formaldehyde emission greater than 1.5mg / L). Only to obtain E1-certified wood products can be used for interior decoration, known as green building materials, absolutely no harm to the human body, E0-class plate is the highest environmental standards of wood-based panels, suitable for children, pregnant women and other resistance Low room decoration of the crowd. E0 grade sheet, refers to the international top environmental standards, formaldehyde emission ≤ 0.5mg / L medium density fiberboard, high density fiberboard, particleboard, oriented particleboard and other furniture can be used for furniture and home improvement wood products, E0, E1, E2 is the detection standard of formaldehyde emission.
Q:Cabinet door environmental protection grade how to divide
Cabinet door of the substrate if it is a density board, then its highest environmental rating is E1 level, and like the double-sided surface of this substrate is the particle board can reach the highest standards of Japan JIS four standard environmental standards
Q:Calcium silicate board is what material
Calcium silicate board for insulation Insulation with calcium silicate board is called microporous calcium silicate, is a white, hard new insulation material, with a light weight, high strength, thermal conductivity is small, high temperature, corrosion resistance, can cut, Widely used in electric power, metallurgy, petrochemical, construction, ship and other areas of equipment piping, wall roof insulation and fire insulation. Thickness is usually above 30mm. Density in the 200-1000kg / m3. Decorative calcium silicate board Decorated with calcium silicate board, calcium silicate board by the United States OCFG company invented, is a comprehensive performance known to the world of new building plate, the 20th century, 70 years in the developed countries to promote the use and development. Europe and the United States, Japan, Australia and Taiwan is the most common use of calcium silicate board countries and regions, China in the early 80s successfully developed, the mid-80s into the development stage, the late 90s to get a large area to promote the application. Thickness of 4-20mm, length and width to 1220 * 2440mm mainly. At the same time to have a large size of calcium silicate board processed into a decorative calcium silicate ceiling, its anti-sagging varieties and other advantages, is widely used in the ceiling.
Q:What is the staircase plate?
Q:How is Fuqing plate?
Environmental aspects: The use of Fuqing Group independent research and development of high-level environmental protection of new plastic, environmental protection level to the highest international F4 star standard and the European E0 standard. F4 star formaldehyde content <0.3mg, E0 level <0.5mg. Truly environmental health.
Q:Home decoration what plate is good?
Skin thickness. See the thickness of the board, the thicker the better the performance, the better the real wood after the paint, the texture is also more clear, bright color saturation is good. How to identify the thickness of the panel? Kanban whether the edge of the sand through the board with or without glue, coated with water to see whether the pan-green, transparent phenomenon. If there is such a problem, it belongs to the panel skin is thin.
Q:PCB sheet problem
It is easy to distinguish between the three are ordinary single-panel, the first is CEM1 material (also may be ceramic materials, but CEM1 material more likely), the second is FR1 material (or FR2, in short, Material), the third is FR4 material. As for the plate manufacturers and specifications of the plate, because the picture is not very clear to see, only know the second for the KB (Kingboard), if there is a real board can be easier to distinguish.
Q:Sound insulation, then, with which plate is good?
Noise barriers / special insulation board: double-sided UV solid board, three boards, X board series    Three layers: thickness 10-20mm, the maximum width of 2100mm, length 6000mm. (Can be customized) There are ten colors available (red, black, lake blue, blue, transparent, opal, advertising white, grass green, green, brown) X-type hollow board: thickness 8-20mm, the maximum width of 2100mm, length 6000mm. (Can be customized) Sound insulation: good sound insulation, can effectively reduce the noise, in the international are the preferred material for highway noise barriers. High strength: polycarbonate sunshine board strength, high security, "not broken glass" and "ring steel" reputation, is the bulletproof glass of high quality materials. Good weather resistance: the use of international advanced production technology, the board evenly distributed high concentrations of UV co-extruded layer, can effectively absorb ultraviolet light, thereby extending the life of the plate. Product Usage: 1. Office buildings, department stores, hotels, villas, schools, hospitals, sports venues, entertainment centers and public facilities of the lighting ceiling. 2. Noise barriers for highways, railways and urban viaducts. 3. Modern plant greenhouse and indoor pool of the sky. 4. Metro entrances, stations, parking lots, shopping malls, pavilions, restrooms, corridors of the canopy. 5. Bank anti-theft counters, jewelry store anti-theft window, police riot shield. 6. The airport, the factory safety lighting materials. 7. Advertising light box panel, advertising display card. 8. Household, office indoor interval, pedestrian access, guardrail, balcony, shower room sliding door.
