Study on the vacuum properties of the meltable polyimide adhensive and its application in vacuum devices 可熔性聚酰亚胺胶粘剂的真空性能研究
2.
The meltable liquid touches with the rotary drum of cooling that form material film in rotary drum appearance . the heat exchange between material film and drum wall makes material film cooling and crystallization . the crystal material film is cut by scraper which forms piece product 转鼓结片是一个冷却结晶过程，料盘中熔融料液与冷却的转鼓接触，在转鼓表面形成料膜，通过料膜与鼓壁间的换热，使料膜冷却结晶，结晶的料膜被刮刀刮下，成为片状产品。
