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:Is the picture below the S modeling faculty do very stiff want to achieve this and exactly the same effect Thank you!

Hello, you should explain what it is to use, where to use. We do the shape of the ceiling, then, are generally made with multi-layer board, in accordance with the requirements in the multi-layer board first arc, and then use the curve machine or trimming machine and other equipment cut.

Q:What kind of sheet is it ok?

The general computer table with melamine board to do a good job, because this plate to do the price is not high, look optional, it is suitable for public choice, there are steel-wood combination

Q:Who has a natural marble sheet testing report template?

Main Test Products Main Testing Products Granite Granite Marble Marble Quartz Stone Quartz Limestone Slate Roofing slate Complex veneer thin stone Artificial marble Artificial quartz stone Artificial quartz stone The following are the same as the " Main Testing Scope Visual dimensions and dimensions Petrographic analysis Gloss Gloss Water absorption Density Flexural strength Compressive strength Thermal shock resistance Abrasion resistance Slip resistance Coefficient of friction Coefficient of friction Frost resistance Fire to Reaction Shore hardness Mohs hardness Mohs hardness Acid resistance Radioactive radioactivity

Q:Black box plate glasses for what kind of person

If the election is more affinity Recommend the kind of color plate Black is the main color, in the edge of the box through the other colors Bright pink and bright blue are good But also a little round of the black box Not the kind of side (some formal) Or when to pick the time to see There is the kind of wrapping a little more upset That kind of wear will be very cute

Q:Know how to help see my description: We told our customers that our PCB is used KB6160 B grade material, and then the customer back to the message said " You are using the KB6160 (FR-4) application of reinforced plate, potentiometer, resistance film field, the lowest level of the kind of plate it! Is very bad.

KB6160 B grade material is defective.

Q:Qianshan Wood Malacca plate how much money a piece

Normal more than 200 to 300 have, too cheap do not easily believe that is likely to be fake, decoration with the plate can not careless, to prevent the use of poor quality sheet, affecting health, choose authentic, in order to simply identify genuine, each There are anti-counterfeit labels on the plate, you can go to the official website query verification.

Q:[Discussion] Why is the ultrasonic flaw rating of plates and forgings inconsistent? In the GB / T 6402-2008 steel forgings ultrasonic testing method forging the ultra-straight probe quality grade is divided into 4, 4 the highest requirements. Single point discontinuous flat bottom hole equivalent diameter ≤ 3mm and GB / 72970-2004 thick steel plate in the ultrasonic testing method provides the quality of steel plate is divided into four levels, one level requirements.

The standard is not the same batch of people to develop, certainly have different ideas, and the most important feature of this standard is copied to the EN10228-3 / 4, the basic is directly followed 1, the more important large forgings surface quality requirements are higher, the general surface area Flaw detection requirements than the heart of a grade as much as the specific requirements, depending on the use of the situation, the surface generally require a higher φ2 or φ3 equivalent 2, steel do not know 3, unqualified generally can not be used, but also hard to say, once we do Over 2 products, a test failed, the first make do with the user, the user test pressure no problem, and then use for many years, another qualified qualified, when the pressure test did not pass, spray a person oil

Q:Why use office furniture

Common furniture with the plate varieties are: solid wood, fiberboard, particleboard, blockboard, plywood and so on. At present, the manufacture of office furniture is mainly used are: fiberboard and particleboard. Low-grade office furniture generally use particleboard, and medium and high-grade office furniture generally use fibreboard. Fibreboard is divided into high density fiberboard (density> 0.8 / cm3), medium density fiberboard (0.5 g / cm3 ≤ density ≤ 0.8 g / cc), low density fiberboard (density <0.5 Gram per cubic centimeter). High density fiberboard due to high density, difficult processing, and easy to nail, the installation of accessories burst; and low density fiberboard due to low density, large gap between wood fibers, easy to water swelling, resulting in surface cladding off, and even the plate disintegration, so the second The use of office furniture are less. The MDF (medium MDF), with the surface smooth, the internal structure of fine, good processing effect, with strong resistance to deformation and load-bearing capacity, And the plate holding nail ability, can be achieved many times disassembly, as in the high-end office furniture of choice. Sunlong's office furniture is used in the manufacturer's custom-made density of up to 0.76 grams per cubic centimeter of the MDF (generally medium density fiberboard density of 0.64 grams per cubic centimeter or so).

Q:Stainless steel wire drawing board, polishing plate, mirror the difference between the three

Stainless steel wire drawing refers to: stainless steel wire drawing is a stainless steel surface like a filamentous texture, this is just a stainless steel processing technology. The surface is matte, carefully look at the top of a trace of a trace of texture, but can not touch out than the general bright stainless steel wear, looks more on the grade of some. Drawing process will be to a certain extent, the loss of stainless steel plate thickness, generally 0.1 ~ 0.2mm. In addition, because the human body, especially the palm of the hand has a relatively strong oil and sweat secretion, stainless steel wire drawing board often touch will leave a more obvious fingerprints, need to regularly scrub. Stainless steel polishing plate refers to: stainless steel polishing plate is polished by polished stainless steel bright plate, this kind of polishing board is generally not high brightness, but also according to the blurred figure. Stainless steel mirror panel refers to: stainless steel mirror panel industry, said the dual 8K plate, also known as mirror panels, grinding fluid through the polishing equipment in the stainless steel plate surface polishing, so that the brightness of the mirror as clear as the mirror. Stainless steel mirror panel from the K number generally: 6K 8K 10K 12K these kinds. From the requirements of the coefficient points are: the general grinding 8K high Pu 8K ordinary grinding 8K fine grinding 8K ultra-fine grinding 8K these types, of course, are getting better and better. Uses: mainly used in building decoration, elevator decoration, industrial decoration, decoration and other stainless steel products. From the difference, the stainless steel wire drawing board is a long strip of lines covered with stainless steel plate. While the polishing plate is cast into a certain brightness of the stainless steel plate. And stainless steel mirror panels, can be collectively referred to as glass-like stainless steel mirror panels.
