Raw kayan don samar da PVC bututu
Raw kayan don samar da PVC bututu,
Ruwan PVC, PVC don samar da bututu,
S-1000 polyvinyl chloride guduro ana samar da shi ta hanyar dakatarwar polymerization ta amfani da vinyl chloride monomer azaman albarkatun ƙasa.Yana da nau'in fili na polymer tare da ƙarancin dangi na 1.35 ~ 1.40.Matsayinsa na narkewa shine kusan 70 ~ 85 ℃.Rashin kwanciyar hankali na thermal da juriya mai haske, sama da 100 ℃ ko dogon lokaci a ƙarƙashin rana hydrogen chloride ya fara bazuwa, masana'anta na filastik suna buƙatar ƙara stabilizers.Yakamata a adana samfurin a cikin busasshen sito mai iska.Dangane da adadin filastik, ana iya daidaita laushin filastik, kuma ana iya samun resin manna ta hanyar emulsion polymerization.
Za a iya amfani da Grade S-1000 don samar da fim mai laushi, takarda, fata na mutum, bututu, mashaya mai siffa, bellow, bututun kariya na USB, fim ɗin shiryawa, tafin kafa da sauran kayayyaki masu laushi.

Ana kera bututun PVC ta hanyar extrusion na albarkatun kasa na PVC, kuma gabaɗaya suna bin matakai iri ɗaya na ayyukan extrusion na bututu:
1.Feeding na albarkatun kasa foda da ake kira guduro da filler a cikin PVC tagwaye dunƙule extruder;
2. Narkewa da dumama a wurare masu yawa na extruder;
3. Fitarwa ta hanyar mutuwa don su zama bututu;
4.Cooling na bututu mai siffa (ta hanyar fesa ruwa akan bututu);kuma
5. Yanke bututun PVC zuwa tsayin da ake so.
Abubuwan da ake amfani da su don samar da bututun PVC sune guduro da filler (wanda aka fi sani da calcium carbonate, ko wanda aka fi sani da duwatsu).Matsakaicin haxin shine kilogiram 1 (kg) na guduro tare da kilogiram 1 na filler.Hanyoyin samarwa galibi ana sarrafa su, tare da ma'aikata suna ciyar da albarkatun ƙasa a farkon tsari, lura da yanayin zafi a cikin tsari da kuma duba samfurin ƙarshe don kowane lahani na zahiri kafin tattarawa da aikawa ga abokan ciniki.An horar da duk ma'aikata kuma suna da ikon yin duk waɗannan ayyuka da dacewa.Babban abu don kera bututun PVC shine kayan foda da ake kira resin PVC.
