Isingeniso senqubo

I-3/4 yemikhiqizo ebunjwe ngokushaywa ikhiqizwa ngokubunjwa kwe-extrusion blow.Inqubo ye-extrusion ukuphoqa impahla ngembobo noma ukufa ukwenza umkhiqizo.

Inqubo yokubumba igalelo le-extrusion iqukethe izinyathelo ezi-5: 1. I-Plastiki preform (ukukhishwa kweshubhu lepulasitiki elingenalutho).2. Vala isikhunta se-flap parison, bopha isikhunta futhi usike i-parison.3. Vuthela isikhunta odongeni olubandayo lomgodi, lungisa ukuvuleka futhi ugcine ukucindezela okuthile ngesikhathi sokupholisa.4. Vula isikhunta bese ususa izingxenye ezishaywayo.5. Sika isibani ukuze uthole umkhiqizo osuphelile.

Inqubo yokubumba ye-extrusion engenalutho
Ukubunjwa kwe-extrusion hollow blow ukuncibilikisa nokwenza ipulasitiki ipulasitiki ku-extruder, bese ukhipha i-parison eshubhu ngokusebenzisa i-tubular die.Lapho i-parison ifinyelela ubude obuthile, i-parison iyashiswa ibe yisikhunta sokushaywa.Umoya ocindezelwe ube usushaywa ukuze wenze i-parison ibe seduze nodonga lwe-mold cavity ukuze kutholwe ukuma kwe-cavity, futhi ngaphansi kwesimo sokugcina ukucindezela okuthile, ngemva kokupholisa nokubunjwa, umkhiqizo oshaywayo utholakala ngokudilizwa.Inqubo ye-extrusion blow molding imi kanje.
Ipulasitiki → ukwenza ipulasitiki ne-extrusion → i-tubular parison → ukuvala isikhunta → ukubumba ukwehla kwamandla emali → ukupholisa → ukuvulwa kwesikhunta → khipha umkhiqizo
Ukubumba igalelo le-Extrusion kungahlukaniswa ngezinyathelo ezinhlanu ezilandelayo, njengoba kukhonjisiwe kuMfanekiso 1-1.
① I-polymer incibilika nge-extruder, futhi ukuncibilika kwakheke kube i-parison ye-tubular ngokusebenzisa idayizi.
②Lapho isonto lifinyelela ubude obunqunyiwe kusengaphambili, isikhunta sokushaywa siyavalwa, isonto liboshelwe phakathi kwezingxenye ezimbili zesikhunta, futhi isonto liyasikwa liyiswe kwesinye isiteshi.
③Jonga umoya ocindezelwe egcekeni ukuze uvuthele i-parison ukuze ulenze libe seduze nendawo yokukhunta ukuze yakheke.
④ Phola.
⑤Vula isikhunta bese ukhipha umkhiqizo obunjiwe.
