Aluminium plate base is one of the basic elements for producing high quality PS plates. So far, there are seven major PS plate base manufacturers in the country, namely, Southwest Aluminum Corporation, North China Aluminum Corporation, Longma Aluminum Corporation, Fujian Ruihao Aluminum Strip Co., Ltd., and Northeast Light Alloy Co., Ltd. Chongqing Aluminum Products Factory and Henan Mingtai Aluminum Industry Co., Ltd.
After years of development, through many years of production research, in recent years, although several major aluminum processing plants in China have made the quality of PS plate aluminum plate bases have been considerably improved, it is necessary to truly achieve the quality of PS plates for aluminum plates. Requirements, we must also work hard to improve the grade and quality of the stability, so as to create the conditions for the popularity of high-grade PS version and CTP version in our country.
So far, no material has been found to replace aluminum in the selection of materials for PS plates. With the vigorous development of China's printing industry, the market and production capacity of PS and aluminum plate bases have grown rapidly. At present, the domestic construction of aluminum foil and foil projects is booming, new companies are emerging, and the technology is changing with each passing day. The market is changing.
Production PS version of the main raw materials: PS version of the special plate, photosensitive adhesive. Here we first talk about the PS version of the special plate, for the production of PS version of the aluminum plate, generally require that it should have the following characteristics:
(1) Have sufficient strength as a support;
(2) Good dimensional viscosity and flatness to ensure printing accuracy;
(3) having a surface state and chemical composition adapted to the template;
(4) There are performance conditions that can be used as commodities.
