Q: Solid wood furniture and panel furniture which pollution is small?: Popular, solid wood furniture is certainly a small pollution, but the market is full of a lot of parallel imports of solid wood furniture, such as solid wood paste, obviously the middle of the particleboard, posted a bark on the outside that is solid wood furniture, furniture and sheet furniture in my It seems there is no difference, choose a good solid wood furniture from the material, technology point of view. General people think that solid wood furniture is certainly all solid wood, but simply not, so when you buy furniture to ask the material, all parts of the material to ask, there is a desktop is solid wood, table legs are not, some desktop is good Wood, table legs with parallel wood, but the price tag is good wood price. Anyway, if you are very stressed that pollution is small, you will see manufacturers have no 10 ring certification, which is the most authoritative environmental certification, of course, people have money to buy another matter on the matter. You'd better buy a brand name, so safe, because to tell the truth, many small workshops which produce furniture, and then to the supermarkets to pay a long lease, transformed into a good furniture, and is completely deceptive. There is to shop around!

Q: My family's kitchen seven-shaped, the amount is a total of four meters, one meter over the top cabinet, put a hood in the middle. Under normal circumstances if the woodworking need a few fire board? Do you need a few sheets?: Cabinet fire board needs an area of 9.4 square meters (including) inside the partition, the specific area of how much (depending on how much), a sheet of 1.22 * 2.44 = 2.97 square meters, estimated the need for fire board (with loss) Four, even the top cabinet came out (these are counted on the table). Door area of about 4 square meters, count down 1.36, the door needs to buy two, but also some of the rich plate. Above for reference, if any access please do not see strange.

Q: Cedar Blockboard Good and Pure Wooden Plate Which is good?: Of course - pure fir blockboard is good Reason: pure fir wood light, not easy to deformation Pure solid wood sheet is not good: Reason: pure solid wood sheet -1, too easy to deformation, no matter what you are supposed to be deformed; On this point will make you wasted decoration money, time is not long but also re-installed

Q: How to pick up the plate: But it is very ugly the best not to find the goods sent to the consultation under the cheap point to give two

Q: What is the difference between wood and wood?: Wood can be called wood logs is the original length to the size, shape, quality standards or special provisions cut into a certain length of the wood section, the wood section called logs. Wood is processed semi-finished products. The use of wood: to be divided into direct use and chemical or special processing to do the use of raw materials. Wood direct use are: construction, pit wood, pillars, sleepers, packaging, furniture, craft sculpture, ships, sports equipment, cultural and educational supplies, musical instruments, decoration, grenade handle, butt, After chemical processing or special processing to do the use of raw materials are: paper, rayon, regenerated cellulose, nitrocellulose, cellulose acetate, ethyl cellulose, hydroxy cellulose, phenyl cellulose.

Q: A5052P ー H34 aluminum alloy sheet number and the meaning of what is the letter?: A5052P rust-proof aluminum alloy, chemical composition%: Si Fe Cu Mn Mg Cr Zn 0.25 or less 0.40 or less 0.10 or less 0.10 or less 2.2-2.8 0.15-0.35 0.10 or less. 5052 for the aluminum alloy grades, it is magnesium alloy (5xxx series are magnesium alloy) one of them, can solve the work hardening, strength comparable to steel. The alloy has good forming processability, corrosion resistance, can be candle, fatigue strength and moderate static strength, used in the manufacture of aircraft fuel tanks, tubing, and traffic vehicles, ship sheet metal parts, instruments, street lamps and rivets, Metal products and so on. "-" The subsequent H indicates that the work hardened state is suitable for products that are enhanced by work hardening, and the product can be subjected to an additional heat treatment that is reduced (or may not) after work hardening. Commonly used aluminum 7075 aluminum alloy plate, 7075 aluminum alloy tube, 5052 aluminum alloy wire, 6063 aluminum coil, 2024 aluminum alloy rod, aluminum alloy profile. Product Standards GB / T3880-2006 "general industrial aluminum and aluminum alloy plate, strip" GB 5237-2004 "aluminum alloy construction profiles"

Q: What is the standard size of the various plates? Decoration in a variety of plate specifications: Furniture plate commonly used specifications: 2440 * 1220mm commonly used thickness: 3mm, 5mm, 6mm, 9mm, 12mm, 15mm, 16mm, 18mm, 25mm.

Q: How to degrease the wood: High temperature drying method High temperature drying is considered to be a more effective degreasing method. Cech [2] has done a degreasing test of Korean pine wood, using a high-temperature drying method to reduce the average rosin by 274% and turpentine by 40 1%. If high temperature drying The rosin can reduce the rosin by 30% and the turpentine can be reduced by 65%. This method is mainly to remove the turpentine of the resinous acid that dissolves the solid because the boiling point of the turpentine is about 1 50 to 2 3 0 ° C, If the coexistence with water can be reduced to below 100 ℃. [3]. Turpentine volatile at high temperatures, and under high temperature steaming conditions to reduce the boiling point of turpentine, while high temperature steam to improve the permeability of wood, can be effective To evaporate the turpentine component, the remaining solid rosin after treatment will not exudate. High temperature plus steam combined dry is the most effective practical method, it does not need to add any equipment only the original drying kiln, so less investment , But many people use it, but some people think that after the role of high temperature and humidity, dry wood after the pine wood surface dark gray, dim, lost the original natural wood color, processed into products after the tan.

Q: What is the PS board? What is his performance? What is his relevant national standard or industry standard?: PS board - polystyrene Is a transparent amorphous thermoplastic material, its light transmission performance after the plexiglass. Advantages are low density, water resistance, light resistance, good chemical resistance. Electrical insulation and moisture absorption performance is excellent, and easy processing and dyeing. The disadvantage is poor impact resistance, brittleness and low heat resistance. Can be used as a blind, sound insulation foam board, can be bonded paper, fiber, wood, marble particles made of composite materials.
