Method for making precoating sensitization etching printing plate

Номер: CN0101387828A
Автор: XIE CHUANDONG, LIU JING, CHUANDONG XIE, JING LIU
Принадлежит:

The invention discloses a production method of precoated photosensitive etching printed board, which precoats a durable photo-induced etching-resist material of stable photochemical property on the surface of a two-layer or multilayer metal plate synthesized by electric plating, vacuum deposition and the like, to prepare a precoated photosensitive etching printed board. In board making, the precoated photosensitive etching printed board can be burnt, developed, etched and removed with film to product a metal printed board. The produced precoated board can be stored without light for at least one year to satisfy the printing demands of anti-false products with large printed mass such as bank notes and valuable securities and the like. The board making can adopt large power UV light source direct board making device (CTcP), to improve the quality of printed boards and the consistence of repeated production. The precoated photosensitive board can reduce the production period of printed boards ...

Returned powder re-sorting method for dynamic powder concentrator of grinding system

Номер: CN115970850A
Автор: XIE CHUANDONG, DING RUI, SONG CHUANJIE, HE ZHENGKAI, AN XIAOPENG, YE JIAYUAN
Принадлежит:

The invention discloses a grinding system and a grinding method. The system comprises a V-shaped powder concentrator, a first dynamic powder concentrator, a roller press and a secondary sorting device for further screening coarse powder output by the first dynamic powder concentrator. In the method, after coarse powder output by the first dynamic powder concentrator is further screened by the secondary sorting device, the screened coarse powder and coarse powder output by the V-shaped powder concentrator are converged and conveyed to the roller press to be extruded, and fine powder enters the V-shaped powder concentrator. The coarse powder returned by the first dynamic powder concentrator is re-sorted, so that the content of fine powder entering the roller press can be reduced, the moisture and temperature of the coarse powder entering the powder concentrator in the roller press are reduced, and stable and efficient operation of the roller press is facilitated.
