Markabka ECTFE Lineed

Weelka safan ee RANA ECTFE wuxuu ka samaysan yahay saldhig bir ah oo leh dahaarka gudaha ee ethylene{0}}trifluorochlorethylene copolymer (ECTFE). Dahaarka ayaa si isku mid ah u daboolay (3mm qaro weyn) iyada oo loo marayo habka dahaarka saxan, samaynta lakab difaac oo cufan. Faa'iidada muhiimka ah ee ay leedahay waxay ku jirtaa 'hydrolysis caabbinta' ee ECTFE -- waxay u adkeysan kartaa waqti dheer-soo-gaadhista heerkul sare iyo uumi-sare (sida 121℃/0.1MPa uumi) iyada oo aan lahayn hydrolysis, taasoo ka dhigaysa mid ku haboon dawooyinka iyo warshadaha cuntada ee u baahan dawooyinka uumiga.

RANA ECTFE weel dahaaran ayaa si weyn loogu isticmaalaa qaababka aseptic farmashiyaha (sida kaydinta ku meel gaadhka ah ee budada lyophilized ee duritaanka), waxyaabaha lagu daro cuntada (sida kaydinta acid liin), iyo waxyaalaha la isku qurxiyo (sida kaydinta udgoonka). Dahaarka ECTFE, kaas oo aan ahayn{1} sun ah oo buuxiya heerarka xidhiidhka cuntada ee FDA (21 CFR 177.1550), waxay ka hortagtaa faddaraynta dhexdhexaadka ah. Intaa waxaa dheer, caabbinta kiimikada ECTFE si ay u milo sulfuric acid iyo sodium hydroxide ayaa ka dhigaysa mid ku habboon kaydinta warbaahinta daciifka ah, taas oo ka dhigaysa doorasho aad u fiican jawi wax soo saar oo nadiif ah.
