Kenyelletso ea ts'ebetso

3/4 ea lihlahisoa tse entsoeng ka leqhubu li entsoe ka mochini oa extrusion blowing.Ts'ebetso ea extrusion ke ho qobella thepa ka sekoting kapa ho shoa ho etsa sehlahisoa.

The extrusion blow molding process na 5 mehato: 1. Plastic preform (extrusion ea sekoti polasetiki tube).2. Koala hlobo ea flap ka parison, koala hlobo 'me u khaole parison.3. Fokotsa hlobo ho lerako le batang la sekoti, fetola ho bula le ho boloka khatello e itseng nakong ea ho pholile.4. Bula hlobo 'me u tlose likarolo tse bululetsoeng.5. Fokotsa flash ho fumana sehlahisoa se felileng.

Extrusion sekoti sekoti ho bopa tshebetso
Extrusion hollow blow molding ke ho qhibilihisa le ho etsa polasetiki ea polasetiki ka har'a extruder, ebe joale extrude parison tubular ka lefu la tubular.Ha parison e fihla bolelele bo itseng, parison e futhumatsoa ka har'a hlobo e otlang.Moea o hatelitsoeng o fefoletsoa ho etsa hore parison e be haufi le lerako la hlobo ea hlobo ho fumana sebopeho sa sekoti, 'me tlas'a boemo ba ho boloka khatello e itseng, ka mor'a hore ho pholisoe le ho bōptjoa, sehlahisoa se bululetsoeng se fumanoa ka ho senya.Mokhoa oa ho bopa extrusion blowing ke o latelang.
Plastiki → polasetiki le extrusion → tubular parison → hlobo koala → inflation molding → pholiso → ho bula hlobo → ntša sehlahisoa
Extrusion blow molding ka kakaretso e ka aroloa ka mehato e mehlano e latelang, joalo ka ha ho bonts'itsoe ho Setšoantšo sa 1-1.
① Polymer e qhibilihisoa ka extruder, 'me e qhibilihang e etsoa parishe ea tubular ka lefu.
②Ha parison e fihla bolelele bo reriloeng esale pele, hlobo ea ho otla e koetsoe, parishe e tlanngoe lipakeng tsa lihalofo tse peli tsa hlobo, ebe parike e khaoloa ebe e isoa seteisheneng se seng.
③ Kenya moea o hatelletsoeng ka har'a parishe ho kenya moea ka har'a parishe ho etsa hore e be haufi le mokoti oa hlobo hore o thehoe.
④ Khutlela fatše.
⑤Bula hlobo 'me u ntše sehlahisoa se entsoeng.
