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:Buy Yiyang plate how to do the problem?

And later consulted their customer service, if you buy back if the inspection found a problem can immediately retreat, found within 24 hours of quality problems can immediately exchange, if the time found within three days of quality problems can be negotiated exchange, in short, the quality is still more secure The

Q:Home to decorate, and ready to ask the carpenter to play furniture, but do not know what plate on the plate is good, small pollution and moisture effect is good, but also ask the bathroom cabinet if you buy plate to play what plate is good? Please have experienced friends to give me guidance, thank you!

Daxing board is decorated with the Secretary for more, more suitable for hand to do, its quality also has several levels, it is characterized by a good grip screw, high strength, with a strong quality, sound absorption, insulation and other characteristics, And the water content is not high, between 10% -13%, processing is simple, the most widely used. But afraid of wet, construction should be avoided to avoid use in the kitchen. The most suitable for use in furniture, doors and windows and sets, partition, false walls, heating hood, curtains and so on High-density board to be hard is a thin fiber, not suitable for hand, suitable for machine processing, do the wardrobe or more appropriate, as the variant. If it is called woodworking is a big core board is good.

Q:Board grade divided into

According to state regulations, the environmental protection level of wood is divided into three categories: E0, E1 and E2. Environmental protection level E0 level: E0 level is the current national standards and related to the detection of ecological sheet of the highest environmental standards. Because the 0.5mg / l formaldehyde content is already a very safe numerical standard. According to relevant information, the formaldehyde content of drinking water is 0.9mg / l, that is, E0 grade formaldehyde content is less than drinking water. Environmental level E1 level: in accordance with state regulations, the indoor plate environmental protection level must be achieved E1 level was considered standard, that is safe and environmentally friendly, the human body will not cause harm. In recognition of the quality of the plate at the same time, the most concerned about the furniture used by the formaldehyde emission of sheet metal. E1-level environmental standards are mandatory national health standards, is mandatory "safety standard line." E1 <= 1.5mg / l, that is, 1.5mg / l formaldehyde content is in line with national standards, is environmentally friendly, harmless to the human body. Environmental level E2: E2 <= 5mg / l, E2 level of formaldehyde content has exceeded the national standard, the current production industry in the plate industry is very few E2 grade, E2 grade products must be treated after finishing to be used Interior decoration.

Q:Will the experts: acetic acid plate and the difference between acrylic, resin sheet

Organic chemical chemical industry is so complicated, only conventional products conventional method, that is, specify the specific conditions. And that are colorless and transparent products it, designated conventional cellulose acetate plate, conventional acrylic plate, conventional thermosetting resin board. Among the three, you can see the degree of colorless translucent to the highest acrylic, followed by resin, acetic acid again. You can see heat conditions, heating to one hundred and fifty degrees above, acrylic will soften the flow, the resin will be soft but not flow, and then raise the temperature, acetic acid will melt. Look at the situation of specific solvents, dip chloroform (chloroform) wipe the surface, acrylic solution, slightly soluble acetic acid, resin unchanged. Of course, for the specific different varieties, the situation is very different

Q:What is the difference between steel sheet and coil?

The plate is the rationale for the price of the coil

Q:What are the European E1 grade environmental standards?

When we buy plates or furniture, we often hear such a term: E0, E1 and E2 So what is E0, E1 and E2? Modern furniture and kitchen cabinets are widely used man-made sheet, in order to make the sheet more robust and durable, wood-based panels need to add moisture-proof agent and adhesive, which is the main source of free formaldehyde. E0, E1, E2 are a formaldehyde emission limit level of environmental standards, the first E1, E2 these two standards produced in Germany, by the "EGGER" to develop, after the introduction of European standards, many domestic companies claim that the E0 standard In fact, Europe did not, the highest standards in Europe for the E (1/2). Specific data are as follows: E2 ≤ 5.0mg / L, E1 ≤ 1.5mg / L, E0 ≤ 0.5mg / L. Meet the E0 standard household products, already belong to the international top environmental standards, formaldehyde emission is almost negligible. E0 is produced in Japan, is the most stringent environmental standards, the equivalent of Europe's E (1/2), according to the plate of formaldehyde and other harmful substances to develop the content. China's environmental standards for 10-30mg / 100mg, equivalent to E2 standards. E1 level is "can be untreated, completely harmless to humans and animals." E0 level is the spontaneous standard of some enterprises, rather than mandatory standards. At present the world only Finland, Japan, the two countries to enforce the E0 standard. In China, to strengthen the implementation of the highest standards of the floor is E1, cabinet industry, the national standard only E2, only part of the high-end products are E1. Therefore, if the purchase of Finland, Japan, the origin of the decoration products, that is, E0-class products, basically can be achieved directly to the standard.

Q:I see the tutorial, in Altium, click the design under the layer stack manager, pop-up layer stack manager, double-click the top layer or core or bottom layer can set some parameters, those parameters can not be set?

Do not set up, with TXT document, named readme can be. Another copper thickness is generally 35um instead of 0.35.

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
