Plasma kai tsaye polymerization tsari
Tsarin polymerization na Plasma yana da sauƙi mai sauƙi ga duka kayan aikin polymerization na ciki da kayan aiki na polymerization na waje, amma zaɓin ma'auni ya fi mahimmanci a cikin polymerization na Plasma, saboda sigogi suna da tasiri mafi girma akan tsari da aikin fina-finai na polymerization yayin da ake yin polymerization na Plasma.
Matakan aiki don polymerization na plasma kai tsaye sune kamar haka:
(1) Vacuuming
Tushen injin polymerization a ƙarƙashin yanayin injin ya kamata a tura shi zuwa 1.3 × 10-1Pa.Don halayen polymerization waɗanda ke buƙatar buƙatu na musamman don sarrafa iskar oxygen ko abun ciki na nitrogen, buƙatun buƙatun buƙatun baya ya ma fi girma.
(2) Cajin amsa monomer ko gauraye gas na iskar gas da monomer
Matsakaicin digiri shine 13-130Pa.Don polymerization na Plasma da ke buƙatar aiki, za a zaɓi yanayin sarrafa kwarara da ya dace da ƙimar kwarara, gabaɗaya 10.100mL/min.A cikin plasma, ƙwayoyin monomer suna ionized kuma an raba su ta hanyar bam na barbashi masu kuzari, yana haifar da barbashi masu aiki kamar ions da kwayoyin halitta masu aiki.Barbashi masu aiki da plasma ke kunnawa zasu iya jurewa Plasma polymerization a yanayin yanayin gas da tsayayyen lokaci.Monomer shine tushen precursor don Plasma polymerization, kuma iskar gas ɗin shigarwa da monomer za su sami takamaiman tsafta.
(3) Zaɓin samar da wutar lantarki
Ana iya samar da Plasma ta amfani da DC, babban mita, RF, ko hanyoyin wutar lantarki don samar da yanayin plasma don polymerization.Zaɓin zaɓin wutar lantarki an ƙaddara bisa ga buƙatun don tsari da aikin polymer.
(4) Zaɓin yanayin fitarwa
Don buƙatun polymer, polymerization na Plasma na iya zaɓar hanyoyin fitarwa biyu: ci gaba da fitarwa ko fitarwar bugun jini.
(5) Zaɓin sigogin fitarwa
Lokacin gudanar da polymerization na Plasma, ana buƙatar la'akari da sigogin fitarwa daga sigogin plasma, kaddarorin polymer da buƙatun tsari.Girman ƙarfin da aka yi amfani da shi a lokacin polymerization an ƙayyade shi ta hanyar ƙarar ɗakin ɗakin, girman electrode, yawan gudu da tsari na monomer, ƙimar polymerization, da tsarin polymer da aiki.Misali, idan ƙarar ɗakin amsawa shine 1L kuma an karɓi RF Plasma polymerization, ikon fitarwa zai kasance cikin kewayon 10 ~ 30W.A karkashin irin wannan yanayi, plasma da aka samar zai iya haɗuwa don samar da fim na bakin ciki a saman kayan aikin.Girman girma na fim ɗin polymerization na Plasma ya bambanta tare da samar da wutar lantarki, nau'in monomer da ƙimar gudana, da yanayin tsari.Gabaɗaya, ƙimar girma shine 100nm/min ~ 1um/min.
(6) Ma'auni a cikin Plasma polymerization
Ma'aunin plasma da sigogin tsari da za a auna a cikin Plasma polymerization sun haɗa da: ƙarfin fitarwa, fitarwa na yanzu, mitar fitarwa, zafin Electron, yawa, nau'in ƙungiyar amsawa da maida hankali, da sauransu.
