Poligrafiya sanoatining rivojlanishi PS varaqlari va alyuminiy plastinka bazasi ishlab chiqarish quvvatlarining tez o'sishiga yordam beradi

PS alyuminiy plitalarni chop etish, oldindan qoplangan fotosensitiv plastinka sifatida ham tanilgan, bosib chiqarish uchun alyuminiy plastinkaga ishora qiladi, Bu ishlab chiqaruvchi tomonidan alyuminiy plastinka ustiga oldindan qoplangan fotosensitiv qatron qatlamiga ega litografik bosma plastinka.. PS plitasi fotosensitiv qatlamdan va qo'llab-quvvatlovchi alyuminiy substratdan yoki plastinka tagidan iborat. Due to the high annual consumption of PS plate, the number of aluminum plates required is also very high. Aluminum plate is not only its important support, but also plays an important role in the performance of PS version.

What alloys are suitable for PS plate?

For the aluminum plate making PS plate, it is required to have sufficient strength, good dimensional viscosity and flatness, and adapt to the surface state and chemical composition of the solution template. Ayni paytda, most PS plates are rolled with 1060 va 1070 aluminum alloys with a thickness of 0.2-0.28mm, and a few are produced with 3003 alyuminiy qotishmasi. 1060-h18 alloy is commonly used. In addition to making PS board for printing, it is also widely used in offset printing boards such as positive PS board, thermal CTP board, photosensitive CTP board and UV-CTP board.

Due to the high requirements for surface quality and flatness of PS plate-based aluminum strip, in order to obtain high-quality PS plate-based strip, a special straightening method must be adopted after cold rolling. Bunga qo'chimcha, the sand mesh value of PS board is generally 0.60 ~ 0.80 m m. In order to obtain finer sand mesh, the internal composition of aluminum plate base is the key, anavi, it is related to the content and composition of trace special metals contained in aluminum alloy.
