Sai dai wasu resin DCPD da aka samar ta hanyar thermal polymerization, Resin Man Fetur sauran duk ana amfani da su ta hanyar cationic polymerization. Ana ƙara abubuwan daɗaɗɗa gama gari a wasu lokuta tare da ɗan hanzari. Siffar cationic polymerization shine ƙimar amsawa. Fast, Man fetur Resin mai kara kuzari yana da sauƙi don dakatar da amsa saboda dalilai kamar ƙazanta ko tsarin kwayoyin halitta a cikin albarkatun ƙasa, don haka ana iya yin polymerized a cikin polymer tare da nauyin kwayoyin halitta na 500 zuwa 2,000, Resin Man wanda ke haɓaka haɓakar danko. tasiri.

Akwai da yawa muhimman matakai a cikin aiwatar da man fetur guduro-zabi da pre-jiyya na danyen mai, Man fetur guduro polymerization na sarrafa albarkatun kasa, neutralization da kuma rabuwa da guduro. Daga cikin su, pre-jiyya na Man Fetur yana da mahimmanci musamman don cire kayan da ba su da kyau a gaba Zabi abinci tare da abubuwan da aka tsara don daidaita kaddarorin guduro na man fetur; Resin man fetur ko dumama don aiwatar da martani. Babban ma'auni na amsawa a cikin tsari shine jimillar ko dangi na abinci, Resin Man Fetur nau'in mai kara kuzari da maida hankalinsa, da zafin jiki. Abubuwan da ke sama dole ne a sarrafa su a hankali Domin samun kyakkyawan amfanin ƙasa, Man Fetur Resin nauyin kwayoyin halitta da rarraba nauyin kwayoyin halitta.

Ana iya raba hanyar polymerization zuwa nau'in tsari, Nau'in Resin Man Fetur, da nau'in ci gaba mai matakai da yawa. Daga cikin su, nazarin nauyin kwayoyin halitta na batch dauki ya fi fadi, Man Fetur da kuma nau'in ci gaba da matakai masu yawa yana da yawan amfanin ƙasa da rarraba nauyin kwayoyin kunkuntar.
