Q: Q235 sheet of the label: The material column to write Q235, followed by the implementation of standards. Do not write standard also line, Q235 the most common, everyone knows.

Q: These two days is very contradictory, before the decoration and the former contract with the master said the use of the plate is E1 level, the plate is really pulled, but her husband saw a lot of scar on the plate above the wood scar, said the decoration master Cheat him, then simply to the plate company to see, know it is true, but I heard there is a E0 level, and now immediately asked the master replaced by this level: If the price difference is not large, then replaced by E0 level, if you are a lot, that is not necessary, because the E0 level no GB, so it is difficult to say how much environmental protection in the end

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: [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: What is the concept of negative ion sheet?: Negative ions with antibacterial, sterilization function, can continue to induce air negative ions, the release of far infrared, to sterilization, antibacterial and improve the role of air cleanliness, high concentration of negative ions, sterilization effect is strong, is the leading environmental health plate , Now do this product is not much

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: Stainless steel plate riveting stainless steel hardware, pressure is not tight. The The Such as riveting stainless steel nuts, studs. Push torque can not reach the standard. High score reward. The There is no solution. The The Give me a solution. The The Non - riveting riveting nuts, studs. Not for that reason Mainly stainless steel is harder In the sheet metal processing can not do any heat treatment The rivet nut is just to lock the screws.: You can use high-strength materials, or with thicker bolts

Q: What kind of domestic brand plate frame good?: Eyes are their own, love the eyes is very necessary, especially after myopia, do not just say where to see where the glasses discount quickly ran with glasses, but the quality of the glasses off the eye damage is very large , The importance of the frame can not be ignored. So when the glasses with the choice of good glasses glasses is the most critical. Now the glasses are better brands are the island, Daming, the United States pupil - Johnson & Johnson, Hai Chang, snow and so on, these are the brand network MAIGOO 2017 top ten glasses brand, you can go to see the above details. Or that sentence, the eyes are their own, not for a moment of cheap on the casual with the pair of glasses, be sure to choose a good brand.

Q: It is said that cloud ecological sheet can be net aldehyde antibacterial, is it true?: I went to the cloud of the official website of the cloud looked, they are using the technology of China and Europe net aldehyde antibacterial patented technology, the official website has a test report and patent certificate, the patent can not do false, have a patent number can be checked, so it should be true Right now. Look at them so well, equal to white to send a 24-hour boot air purifier, I have a little heart, and back to play when the furniture to try.

Q: Plate market, the so-called eight major markets, where is the four bases?: Shandong Province Linyi City Yitang Town Hebei left the village of China's four northern man-made board production base in Jiangsu Pizhou and Suqian, Shandong Linyi and Heze Shandong Linyi, and a few Yintang town plate manufacturers,
