1. Njira yopangira zinthu zapulasitiki ndi njira yopangira mabotolo apulasitiki, omwe amatanthawuza njira yopangira pulasitiki yomaliza kuchokera ku polima yopangidwa ndi fakitale yopangira utomoni.
2. Njira zopangira (ndi pulasitiki) zikuphatikizapo: kuponderezedwa (kuumba), extrusion (extrusion molding), jekeseni (kuumba jekeseni), kuwombera (kuumba kopanda dzenje), calendering, etc.Kupanga kwapadera:
⑴ kuponderezana: kuumba kapena kukanikiza kuumba. Amagwiritsidwa ntchito kwambiri popanga mapulasitiki otenthetsera kutentha monga phenolic resin, urea-formaldehyde resin ndi unsaturated polyester resin.
⑵ extrusion: extrusion akamaumba, ndi ntchito makina extrusion (extruder) adzakhala mkangano utomoni mosalekeza mwa nkhungu, extrusion chofunika mawonekedwe a mankhwala method.Extrusion Komanso nthawi zina ntchito mu thermosetting akamaumba pulasitiki, ndipo angagwiritsidwe ntchito akamaumba a thovu plastics.The ubwino extrusion ndi kuti akhoza extrude akalumikidzidwa zosiyanasiyana za mankhwala, dzuwa mkulu kupanga, basi ndi mosalekeza kupanga; The sangathe ndi chingwe pulasitiki thermosetting sangathe ankagwiritsa ntchito njira processing, mankhwala kukula mosavuta kubala kupatuka. .
⑶ jekeseni akamaumba: jekeseni akamaumba. jekeseni akamaumba ndi ntchito jekeseni akamaumba makina (kapena jekeseni makina) kuti thermoplastic chingwe kusungunula pansi kuthamanga mu nkhungu pambuyo kuzirala, kulimba kupeza mankhwala method.Injection akamaumba angagwiritsidwenso ntchito mapulasitiki thermosetting ndi thovu pulasitiki chingwe akamaumba.Injection akamaumba ali ndi ubwino wa mofulumira kupanga liwiro, dzuwa mkulu, mpheto basi, ndipo akhoza kuumba mbali zovuta, makamaka oyenera kupanga misa.The kuipa ndi kuti mtengo wa zida ndi nkhungu ndi mkulu, ndi jekeseni. akamaumba makina n'zovuta kuyeretsa.
⑷ kuwomba: kuumba kopanda dzenje kapena kuumba kozungulira. Kuwomba ndi njira yowombera zinthu zopanda pake ndi kukakamiza kwa mpweya woponderezedwa kuti utomoni wotentha utsekeke mu nkhungu.Kuwomba akamaumba zikuphatikizapo njira ziwiri nkhonya akamaumba filimu ndi kuwomba akamaumba dzenje products.With nkhonya akamaumba njira akhoza kutulutsa mankhwala filimu, zosiyanasiyana mabotolo, migolo, POTS ndi zidole ana.
⑸ Kalendala: Ndi njira yopangira momwe utomoni ndi zowonjezera zina zimasinthidwa (kukanda, kusefa, ndi zina zotero) kukhala mafilimu kapena mapepala kupyolera mu mipata pakati pa ma roller awiri kapena kuposera otsutsana a kalendala, omwe amachotsa chogudubuza. kalendala, ndiyeno kuumbidwa ndi cooling.Calendering zimagwiritsa ntchito polyvinyl kolorayidi akamaumba njira utomoni, akhoza kupanga filimu, pepala, mbale, yokumba zikopa, matailosi pansi ndi zinthu zina.
Yantai Dongyuan Plastic Products Co., Ltd.PE pulasitiki chingwe ukonde, North Korea hemp (PP) zakuthupi ukonde, mankhwala feteleza hoisting ukonde, katundu hoisting ukonde, galimoto kusindikiza ukonde, chitetezo ukonde, kuswana chingwe, sitima chitetezo ukonde ndi zina zapadera specifications. ukonde woluka ndi manja, ukonde wotetezedwa, womwe umagwiritsidwa ntchito kwambiri padoko, mabizinesi opangira feteleza, mabizinesi opangira tirigu ndi mafuta osungira chakudya cha soya ndi transportation.Zingwe za polyethylene (PE) ndi Korean hemp (PP) zimagwiritsidwa ntchito kwambiri m'makampani, ulimi. ndi usodzi.
