War sidee dareeraha ah P4 loo isticmaalo?

reagent loo isticmaalo taranta ee rinjiga nooca PSC PSC lihida iyo LIS, aasaas u ah wax soo saarka kuwaas oo koloriin Beeyada polyvinyl chloride, Beeyada epoxy, copolymers chloride vinylalkohol iyo qaar ka mid ah waxyaabaha kale ee film-sameynta.

Keeneysa - sida loo milo P4 rinjiga dareeraha ah?

P4 dareeraha lagu darayaa in wax gaar ah (xabagta ama rinjiga) ee qaybo yaryar oo ilaa joogta ah la doonayo. rinjiga la rijeynaya (xamuurada) waxay u baahan tahay u qaboobo joogto ah.

Ka dib codsanaya daahan diyaar u baxa dareeraha iyo waxyaabaha xoojiyaan film-sameynta ee, bedalayo daahan difaac. Waxaa muhiim ah marka la dareeraha ah ka shaqeeya si looga fogaado ingress oo biyo ah qayb ka mid ah acetone ku dhaba isku daraan laga yaabaa in la, iyo this markeeda waxay keeni doontaa in dhalanrog ka mid ah midabka ama caddeeyo of jubbadda cad.
