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:PCB board material how to identify

PCB board material identification, can be carried out from the following four aspects: (1) dimensional stability In addition to pay attention to X, Y axis (fiber direction and horizontal direction), but also pay attention to the Z axis (plate thickness direction), due to thermal expansion and contraction and heating reduction factors easily lead to silver plastic conductor fracture. (2) electrical and water absorption FR-1 is better than FR-1 and XPC in terms of dimensional safety, electrical and water absorption, so that the insulation of the insulator in the absorbent state is reduced, so that the metal is moved under the potential difference. Production of silver through-hole printed circuit board, to use special FR-1 and XPC paper substrate. (3) ductility Copper plating through the copper hole is a continuous crystal, there is a very good ductility, not like silver, carbon ink in the thermal expansion and contraction, easy to interface separation and reduce the conductivity. (4) migration Silver and copper are metal materials, easy to oxidize and restore the phenomenon caused by rust and migration phenomenon, due to the difference in potential, silver than copper in the potential difference between the trend of prone to silver migration (Silver Migration). Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit.

Q:Home decoration cabinet made with what plate is good? How is the Malacca plate?

Malacca is a tropical tree species from Indonesia, the Philippines and other places. Malacca core has a lot of advantages, relatively smooth, relatively homogeneous wood, foreign splicing is good, after drying to the domestic processing after processing made Malacca ecological board more suitable for: home decoration, wardrobe and so on.

Q:Recently we received a lot of customers to reflect, said to buy their own snowflake sheet, the results go back after use, the taste is great, even worse, the board labeled furniture has not long, there has been damp deformation situation. Customers are very angry, we are also confused.

Recently we received a lot of customers to reflect, said to buy their own snowflake sheet, the results go back after use, the taste is great, even worse, the board labeled furniture has not long, there has been damp deformation situation. Customers are very angry, we are also confused. However, it is the most environmentally friendly sheet on the market, and the formaldehyde emission of the E1 grade (0.5 <formaldehyde emission <1.5) sheet is similar to that of the same type of sheet, although the plate price is relatively high. The brand claims to be the E0 level release standard. Many customers are directed at the brand of snow. We do is the conscience of business, bright business, snow shop in the flagship store sold to our customers are the lowest price, the floor is very low profit, are by running the amount to earn meager profits, of course, each A sheet of hair issued to the we are checked, and will never appear cracks, flaws. In the flagship store to buy Xuefeng ecological board, we will carefully selected for the customer out of the same batch of goods, to ensure a high degree of unity of the panel color. Will never appear shoddy situation to deceive consumers, which is undoubtedly pick up the stone hit his feet, we will never make this self-destructive brand image of the act. We compare the documents, compared to the decorating company, and finally concluded: these customers are not buying snowflake sheet. Now the market is not a lot of qualified small decoration company, the name of the shiny brand name, to higher than the price of ordinary plate, to sell the brand of wooden plywood, often do not understand the decorating industry customers Deceived, which is our snow brand is also a damage.

Q:Many types of flooring, which OKorder is suitable for several floor plate?

Heart material brown to reddish brown, texture staggered, usually with deep and white stripes; wood with luster; no special smell; thick but uniform wood, with yellow minerals; heavy hard, material stability, beautiful pattern, heart material pressure. can resist termite harm. High strength wood, wear, smooth after the plane, easy to paint, dry and good stability. the price is moderate; in the solid wood floor in the relatively high cost, the world generally like to use high-quality furniture, flooring, window decoration, frame and doors, boats and bridges.

Q:There are several pieces of decoration plate?

Decorative materials are divided into two parts: part of the outdoor materials, part of the indoor materials. ? Indoor materials and then divided into real materials, sheet, sheet, profiles, wire five types.

Q:What is the integrated ceiling UV board

Is a kind of craft, like love home integrated ceiling heat transfer the same

Q:What is the overall cabinet?

Stainless steel is also good

Q:How about the top 100 board furniture

Bought his family more than seven thousand yuan of plate, the price of high quality times. Just received the goods, a look at selling good, knock knock, the sound is crisp, touch very smooth, very texture. Well, hundred of the brand, very good.
