Q:What kind of woodworking board decoration
Well, do not know what you are where ah, Guangdong side of it, the middle of the general level of closet received 1500-2000 yuan / m between the specific made what kind of first look at your needs, the second look at the work People's conscience. In fact, because the difference between the specifications of the cabinet, the price will be much worse, hard to say. If you must do, and your economic capacity is acceptable, it is recommended to use 12% plywood to do the frame, ash or other board to do the surface, all the cabinet inside the cover plate, called paint a layer of thin mud powder, polished Well, brush three times, okay. The The We have a good crown here. But also a lot of fake. The plate is really messy. The An accidentally fooled. The In fact, buy and do the cost of almost, but save a lot of time. But the quality of the same thing to do the same cost of spending is indeed worse than to do.
Q:TR-90 cp pc plastic glasses frame difference, as well as what is the material sheet! Physical properties how?
TR90 spectacle frame surface lubrication, the density of 1.14-1.15, on the saline will float, than other plastic glasses frame light, about half of the weight of the plate material, nylon material is 85%, can reduce the bridge of the nose, the burden of the ear, suitable for young people . It is very resistant to wear, good chemical resistance, solvent resistance, weather resistance is good, not easy to burn, high temperature. And it is memory of the polymer material, anti-deformation index 620kg / cm2, not easy to change because TR90 material Eyeglass frame elasticity, toughness, easy to break, strength, no rupture, so it has sports safety. And it is very resistant to impact: more than 2 times the nylon material, ISO180 / IC:> 125kg / m2 elasticity to effectively prevent In the movement due to impact on the eye damage. No chemical residue release, in line with European food-grade materials requirements. TR90 material than other pc, cp and other frames material is much more expensive, and the production process is also more stringent, so TR90 glasses frame price than the other to be several times more expensive. CP: refers to propionic acid frames PC: refers to the plastic frames, made of polycarbonate Material: The material is made of high-tech plastic memory plate. Ingredients: Most of the current sheet metal components are acetate fiber, there are a few high-grade frame is propionic acid fiber, while the acetate fiber sheet is divided into injection molding and pressing Type, injection molding is the name of the mold is made of water, but most of the current is to suppress the processing of sheet metal glasses in terms of the origin of the plate in France and Italy, the plate is better, Japan is also quite good, many high-end sheet glasses Based on these high-quality sheet, and therefore more reliable quality.
Q:What is the E0.E1 level standard in the plate?
The E0 grade of the sheet is the concept of formaldehyde emission limitation in the new national standard GB / T9846.1-9846.8-2004. The standard divides the formaldehyde limit level into three levels, namely: E1 level free formaldehyde release limit ≤5.0mg / L (meet the domestic standard), E1 free formaldehyde release limit ≤ 1.5 mg / L (in line with European standards), E0 level free formaldehyde release limit ≤ 0.5 Mg / L (the world's top standard).      E0 grade plate although the environmental standards are higher, but because it does not contain green moisture-proof agent and adhesive, its toughness and moisture resistance is relatively low, easy to tide fracture, generally used as furniture substrate, not suitable for use in the kitchen wet Environment. In addition, due to the higher price of E0 grade plate, consumers are usually unbearable, generally choose E1 grade plate.
Q:What is the difference between a sunglasses or a sheet of plastic?
Remove the sunglasses lens quality factors, the greatest impact on the price of sunglasses should be brand value-added and material caused by the different costs. Brand value added here is not discussed, this thing in the selection of sunglasses when the wise, can not tell a right and wrong. Then we talk about the material of the sunglasses frame. Compared to other materials, the use of sheet and plastic sunglasses frame on the surface is not see the difference. First of all, the plate frame is a memory function, if you buy the sunglasses mirror legs for you too tight or too loose, then you can adjust the mirror legs, straighten the bend is not a problem, but also inside and outside the bending Adjustment. If it is a plastic material sunglasses frame, a small adjustment does not work, it will automatically change back to the prototype, if a substantial adjustment - it will not change back to the prototype, because it has been broken ... Secondly, from the details, the frame of the frame to wear more comfortable, the basic will not appear discomfort. The plastic frame in addition to the overall structure is relatively stiff, is not conducive to the adjustment, the external paint may also be processed, there will be irritating smell. Finally, the frame of the frame will have steel (think of reinforced concrete, there are wood), durable. Plastic frame it, in addition to plastic or plastic, can be used to know how long days. So look at the appearance, you can not find the difference between these sunglasses.

Q:How does the composite sheet distinguish between acrylic and PC?
Do not know what you said PC is what, acrylic, well recognized ah, take a lighter, get one or two acrylic point, and burn nothing is acrylic, understand?
Q:Is it ok in the decoration? What are the materials used in general?
Decoration in the proposed do not do too much fixed furniture will make space flexibility worse And then because of the current market varieties and styles of furniture are new and do not necessarily meet your mind but in the market selection is certainly their favorite will choose but like a wardrobe and the like can be made into a fixed because it Usually exist in a corner of the room does not affect the overall space flexibility Plate it is generally integrated plate must pay attention to the environmental level of the plate Oh E0 and E1 is a poor
