Tsarin polymerization kai tsaye na plasma

Tsarin polymerization kai tsaye na plasma

Tsarin polymerization na Plasma yana da sauƙi ga kayan aikin polymerization na ciki na lantarki da kayan aikin polymerization na lantarki na waje, amma zaɓin sigogi ya fi mahimmanci a cikin polymerization na Plasma, saboda sigogi suna da tasiri mafi girma akan tsari da aikin fina-finan polymer yayin polymerization na Plasma.

Matakan aiki don polymerization na plasma kai tsaye sune kamar haka:

(1) Yin amfani da injin tsotsa

Ya kamata a yi amfani da injin polymerization na bango a ƙarƙashin yanayin injin zuwa 1.3 × 10-1Pa. Don halayen polymerization waɗanda ke buƙatar buƙatu na musamman don sarrafa abun ciki na iskar oxygen ko nitrogen, buƙatar injin tsabtace bango ya fi girma.

(2) Monomer na cajin amsawa ko gaurayen iskar gas na mai ɗaukar iskar gas da monomer

Matsayin injin tsabtace iska shine 13-130Pa. Don aikin polymerization na plasma da ke buƙatar aiki, za a zaɓi yanayin sarrafa kwararar ruwa mai dacewa da ƙimar kwarara, gabaɗaya 10.100mL/min. A cikin plasma, ƙwayoyin monomer suna ionized kuma suna rabuwa ta hanyar fashewa na ƙwayoyin mai kuzari, wanda ke haifar da ƙwayoyin aiki kamar ions da kwayoyin halitta masu aiki. Ƙwayoyin aiki da plasma ke kunnawa na iya fuskantar polymerization na Plasma a mahaɗin matakin iskar gas da matakin ƙarfi. Monomer shine tushen precursor don polymerization na Plasma, kuma iskar amsawar shigarwa da monomer za su sami takamaiman tsarki.

(3) Zaɓin samar da wutar lantarki mai motsawa

Ana iya samar da plasma ta amfani da tushen wutar lantarki na DC, mita mai yawa, RF, ko microwave don samar da yanayin plasma don polymerization. Zaɓar samar da wutar lantarki ana ƙayyade shi ne bisa ga buƙatun tsarin da aikin polymer.

(4) Zaɓin yanayin fitarwa

Don buƙatun polymer, polymerization na plasma na iya zaɓar hanyoyi biyu na fitarwa: 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, halayen polymer da buƙatun tsari. Girman ƙarfin da aka yi amfani da shi yayin polymerization ana ƙayyade shi ta hanyar girman ɗakin vacuum, girman electrode, ƙimar kwararar monomer da tsari, ƙimar polymerization, da tsarin polymer da aiki. Misali, idan girman ɗakin amsawa shine 1L kuma an karɓi polymerization na Plasma na RF, ƙarfin fitarwa zai kasance cikin kewayon 10 ~ 30W. A ƙarƙashin irin waɗannan yanayi, plasma da aka samar zai iya haɗuwa don samar da siririn fim a saman aikin. Yawan girma na fim ɗin polymerization na Plasma ya bambanta da samar da wutar lantarki, nau'in monomer da ƙimar kwarara, da yanayin tsari. Gabaɗaya, ƙimar girma shine 100nm/min~1um/min.

(6) Ma'aunin ma'auni a cikin polymerization na Plasma

Sigogin plasma da sigogin tsari da za a auna a cikin polymerization na Plasma sun haɗa da: ƙarfin fitarwa, kwararar fitarwa, mitar fitarwa, zafin jiki na Electron, yawa, nau'in rukunin amsawa da yawan aiki, da sauransu.
