- Q:What are the top ten brand names in 2017?
- New Zealand Chi cabinet sheet using the new water-based polymer isocyanate gum,
Environmental protection level to the highest national E0 standard, it belongs to the non-formaldehyde series,
Completely away from the formaldehyde, benzene and other harmful substances on the human body harm,
While preserving the aroma of natural logs
- Q:PCB sheet problem
- Only from the picture, it is difficult to judge, such as the picture should be a single panel, the first white substrate may be rogers some models may also be cem-1. The third type may be glass fiber cloth fr-4.
In fact, the use of plate to see the nature of the circuit and the use of the environment. For example, there is no special circuit can be used fr-1.fr-4.cem-1 can be. High circuit frequency can be used Rogers series plate, more than 5g frequency should be used ptfe microwave plate.
- Q:What is the difference between pine furniture and sheet metal furniture?
1 pine wood furniture selection, design and manufacture of pine coniferous forest species, due to high forest coverage, all the trees are basically gone.
2 artificial pruning, making the processing into the material, the branches are left behind the natural
The traces of growth. In the making of furniture, more fully demonstrated
Material is real, foolish and natural beauty.
3 Most of the pine furniture modeling simple and generous, full of smooth lines, less carving processing methods of environmental health.
4 good pine furniture after regular maintenance, the general use of life
Life longer, maybe also as a family heirloom generation pass it!
5 high-quality pine furniture will emit a unique smell of logs, may have just started some people will not get used to, but this is special
Special smell of the human body is not only harm and also conducive to good health Oh.
1 oak furniture, wood is relatively hard, relatively strong stability, texture is relatively clear, made out of furniture durable, very simple fashion. Made out of the furniture are very upscale, especially suitable for European furniture.
2 oak structure rough, elegant color, wear resistance, a lot of decoration, furniture, flooring and so on materials, have chosen to use oak to create. Practical comparison of wide, highly absorbent, but also corrosion-resistant, with it to do the quality of solid wood furniture is very good.
3 oak material because the comparison in the country less, so the relatively high price of oak furniture. Oak furniture, hard texture, in fact, it is its shortcomings, so that the moisture in the furniture is not easy to completely dry, a long time more easily rotten.
4 oak furniture is relatively easy and rubber wood furniture confused, will affect the consumer's judgment. In the domestic oak furniture, although the process is very good in all aspects, but the general oak furniture is not a good maintenance, then after a year or so may be the old contraction.
- Q:Black box plate glasses for what kind of person
- To wear black-rimmed glasses actually require quite high
Look at the face and color
- Q:What are the differences between FR5 sheet and FR4 sheet?
- FR-5 has a better advantage than FR-4:
1, TG, TD higher;
2, heat resistance is better, about twice the normal FR-4;
3, Z-CTE smaller, suitable for high multi-layer board;
4, T288 better.
FR4FR5 epoxy board by a special electronic cloth impregnated with epoxy phenolic resin and other materials by high temperature and high pressure hot plate made of laminated products. With high mechanical properties and dielectric properties, good insulation properties and heat resistance and moisture resistance, and a good mechanical processing. Application: for electrical and electrical equipment for the insulation structure of parts, also widely used In the PCB test; and can be used in humid environmental conditions and transformer oil. Specifications:. Plate: Thickness x Width x Length = 0.3 ~ 50mmx1020mm x 1220mm
- Q:What is the lower formaldehyde content of solid wood furniture than plate furniture?
- Formaldehyde in furniture is mainly from those composite sheet, as well as paint, these plates inside the adhesive will continue to release formaldehyde.
Furniture surface, it is best to use liquid in addition to formaldehyde reagent spray, or brush, and now popular floor with photocatalyst wood oil and furniture with Maya blue liquid, you can find their own search for a suitable method.
Volatile to the air part of the best choice of strong adsorption, absorbent time lasting materials, such as Maya blue to attapulgite clay as the main component of the product, because the attapulgite clay has a lot of microwave pores, surface area, absorb formaldehyde To specifically counterparts.
Of course, mainly ventilation, a variety of formaldehyde in addition to the above methods are in the premise of ventilation.
- Q:Novice: stainless steel plate calculation and weighing what is the meaning? more specific
- Stainless steel plate calculation and weighing the meaning of stainless steel through the length of the width and wall thickness using the formula to calculate the weight of stainless steel. The pounds are rated directly to the scales that weigh the stainless steel. Stainless steel can be used as a reference. The actual delivery is subject to weight.
In fact, it should be said that the price of pounds than the expensive calculation
Because the weight of the calculation will be heavier than the actual weight.
Probably the actual:
Attached to the formula:
Stainless steel square tube calculation formula: (length + width -2 times wall thickness) * wall thickness * 0.0158 = kg / m
Where the length, width, respectively, refers to the long side of the square tube and short side, the unit is mm.
Stainless steel tube calculation formula: (diameter - wall thickness) × wall thickness × 0.02491 = kg / m
The unit is in millimeters.
The above weight is for 304 stainless steel. Can be used as a reference. The actual delivery is subject to weight.
- Q:What are the CTP plates?
- Photopolymerized media This type of plate is usually made of aluminum, photosensitive layer and surface layer. The photopolymerizable layer is mainly composed of a polymerized monomer (+ oligomer), an initiator, a spectral sensitizer and a film-forming resin. The initiator is widely used as a multi-initiator system with high quantum efficiency. The effect of the spectral sensitizer is to effectively extend the range of the initiator to the luminescence wavelength region of the laser. It can now extend to 488nm (ion laser) and 532nm ( Multiplied YAG laser). The role of the surface layer is mainly the atmosphere of oxygen molecules separated, to avoid its into the photosensitive layer, in order to improve the photosensitive layer of the chain growth efficiency, resulting in high sensitivity. As a result of these effective measures, the photopolymerization of the direct plate of the sensitivity has been greatly improved, the minimum imaging exposure has dropped to about 10μJ / cm2, second only to the silver salt type of direct plate, and this plate structure Simple, resolution, printing rate and post-processing and conventional PS version similar or even better. Since the range of intrinsic photoreactivity of most efficient initiator systems is in the ultraviolet region and the photometric range extends to the range of the emission wavelength of the UV-LD laser, the photopolymerized direct plate will become the next generation of UV direct Preferred system, has a very good development prospects.
- Q:Now buy their own plate to find workers to do live wardrobe cost-effective or buy wardrobe cost-effective?
- LZ this problem is a common phenomenon, the fundamental reason is the plate formaldehyde emission exceeded the serious, endangering human health, national environmental standards are E1 level, formaldehyde emission <1.5mg / L, E0 grade formaldehyde emission <0.5 Mg / L, the domestic plate can really produce E0-level manufacturers, imports of sheet metal in this area much better, such as the crown plate of the environmental protection level made the California CARB certification, formaldehyde emissions to California, the most stringent environmental Requirements; also won the "F4 Star" standard (Japan floor standards the highest health level, but also considered the world's most healthy floor standards.If the usual E1, E0-level standards, then the "F3 star" quite In our country E0 standard, it is recommended to limit the use of area, "F4 star" is much higher than the "F3 star", formaldehyde emission <0.1mg / L). The overall use of the wardrobe board formaldehyde release is much higher than the board, but the business with formaldehyde skills, consumers can not smell it, choose a good plate, after renovation, immediately stay, but also smell the smell
