Tsarin samar da bututun PVC:

Mixing → Kneading → extrusion granulation → extrusion forming → traction → coiling → marufi → ingancin dubawa → gama samfurin

1. Kneading na sinadaran

Ana auna kowane nau'in albarkatun ƙasa daidai kuma a saka su cikin ƙwanƙwasa cikin wani tsari.Jerin ciyarwa: Gudun PVC, Plasticizer, stabilizer, mai mai.Lokacin da zafin jiki ya kai 100 ~ 110 ℃, ana iya fitar da kayan.

2.extrusion granulation

Wannan tsari don sarrafa zafin jiki, mafi girman batu na kayan zafin jiki ya kamata a sarrafa shi a mafi girma fiye da zafin jiki na narkewa, ƙananan zafin jiki na extrusion, wato, tsakanin 155 ~ 160 ℃.Granulation ya kamata a cimma manufar cikakken hadawa da fara filastik.

Zazzabi na kowane yanki na granulator kamar haka:

Yanki na 80 ~ 90 ℃;Yanki na 130 ~ 140 ℃;Yankuna uku 140 ~ 150 ℃;Fara daga 150 ~ 160 ℃.

3. extrusion tube kafa

The zafin jiki na extrusion tube kafa ya dan kadan mafi girma.Gabaɗaya, madaidaicin bututu yana da alaƙa da haɓakar zafin jiki.A cikin wani takamaiman yanayin zafin jiki, ƙimar zafin jiki mai girma yana da kyau, kuma akasin haka.A lokaci guda, saurin juzu'i da saurin sanyaya zai shafi bayyananniyar bututu.Gudun juzu'i ya fi girma kaɗan, saurin sanyaya yana da sauri, kuma gaskiyar bututun ya fi kyau.Gudun juzu'i shine gabaɗaya 10% ~ 15% sauri fiye da saurin extrusion.Ana fesa sanyin bututun da aka bayyana da ruwan sanyi a lokacin mutuwar hanci sannan a sanyaya a cikin tankin ruwa.

Zazzabi na kowane yanki na gyare-gyaren extrusion kamar haka:

Yanki 1:90 ℃;Yanki biyu 140 digiri 5 ℃;Yankuna uku 160 digiri 5 ℃;Yankuna hudu 170 digiri 5 ℃.

4. PVC tiyo extrusion kariya:

1. kai tsaye tare da foda extrusion gyare-gyare, da yawan zafin jiki na extruder ne game da 5 ℃ m fiye da granular abu.

2. Baya ga ƙarami diamita (φ60mm a kasa) na bututu blank sanyaya baya bukatar a hura a cikin matsawa iska, da ya fi girma diamita na tube blank sanyaya dole ne a hura a cikin tube matsa iska, domin tabbatar da daidaito da kwanciyar hankali na girman diamita na bututu.Kula da barga matsa lamba na matsa iska.

3. Kula da kwanciyar hankali na saurin haɓakawa kuma ku guje wa canjin diamita na bututu ko kauri na bango wanda ya haifar da rashin kwanciyar hankali.

4. Idan na'urar ta mutu na dogon lokaci, dole ne a wargaje ta kuma a tsaftace ta don guje wa matsalolin lalacewa.
