Izindaba Zenkampani

Imikhiqizo yepulasitiki yenziwe ngengxube ye-resin yokwenziwa kanye nezithasiselo ezihlukahlukene njengezinto zokusetshenziswa, kusetshenziswa umjovo, i-extrusion, ukucindezela, ukuthela nezinye izindlela. Ngenkathi imikhiqizo yepulasitiki ibunjwa, iphinde ithole ukusebenza kokugcina, ngakho ukubumba kwepulasitiki kuyinqubo eyinhloko yokukhiqiza.

1. Ukubumba umjovo kubizwa nangokuthi ukubumba umjovo. Kuyindlela yokusebenzisa umshini womjovo ukujova ngokushesha ipulasitiki encibilikisiwe esikhunjeni bese uyiqinisa ukuze uthole imikhiqizo ehlukahlukene yepulasitiki.

2. Indlela yokubumba i-extrusion iyinqubo esebenzisa ukuzungeza isikulufu nokucindezela ukuze ukhiphe ngokuqhubekayo ipulasitiki yepulasitiki ibe isikhunta, futhi lapho udlula ngendlela ethile yokufa, iphrofayili yepulasitiki efanelekile ukuma kwefa iyatholakala.

3. I-Compression molding, eyaziwa nangokuthi i-compression molding, i-compression molding, i-compression molding, njll., iwukwengeza ama-pellets aqinile noma izingcezu ezenziwe ngaphambili esikhunjini, futhi usebenzise ukushisa nokucindezela ukuze kuthambe futhi kuncibilike, futhi ngaphansi kwengcindezi Indlela yokugcwalisa. isikhunta ukuze uthole izingxenye zepulasitiki ngemuva kokwelashwa.

4. I-Blow molding (eyokucutshungulwa kwesibili kwamapulasitiki) kuyindlela yokucubungula lapho ama-parsons angenalutho epulasitiki ashaywa khona futhi akhubazekile ngomoya ocindezelwe, futhi izingxenye zepulasitiki zitholakala ngemva kokupholisa nokubunjwa.

5. Ukubunjwa kwepulasitiki kufana nokubunjwa kwensimbi. Okusho ukuthi, impahla ye-polymer noma impahla ye-monomer esimweni esigelezayo ijovwa esikhunjeni esithile, futhi ngaphansi kwezimo ezithile, iyasabela, iqiniswe, futhi yenziwe ngendlela yokucubungula izingxenye zepulasitiki ezihambisana ne-mold cavity.

I-6.I-Gas-assisted injection molding (okubizwa ngokuthi i-gas-assisted molding) iyindlela entsha emkhakheni wokucubungula ipulasitiki. Ihlukaniswe yaba ukwakheka okungenalutho, ishothi elifushane, kanye neshothi ephelele.
