Kungakanani okwaziyo ngenqubo yepulasitiki?

Kungakanani okwaziyo ngenqubo yepulasitiki? Ukwethulwa kwezindlela zokwelapha zepulasitiki ezivamile.

Isihloko sokugcina sethule izindlela ezine zokucubungula amapulasitiki, futhi namuhla sizoqhubeka nokuzethula. Ngicela ungilandele futhi ufunde.

(5) Vuthela Ukubumba.

Ukubumba i-Blow kuyindlela yokubumba yokwenza imikhiqizo yepulasitiki engenalutho. Isebenzisa umfutho womoya ukuze ishaye into engenalutho embotsheni yesikhunta ibe umkhiqizo ongenalutho.

(6) Ikhalenda.

I-Calender yisinyathelo sokugcina ekuqedweni kwesikhumba esinzima. Isebenzisa i-plasticity ye-fiber ngaphansi kwesimo sokuxuba ukushisa ukuze iqhube ubuso bendwangu yendwangu noma ukukhipha imigqa e-oblique ehambisanayo ukuze kuthuthukiswe ukucwebezela kwendwangu. Ngemva kokuba impahla yondliwe, iyashiswa futhi inyibilike, bese yenziwa amashidi noma ulwelwesi, olupholile futhi lugoqwe. Izinto ezivame kakhulu ze-calendering yi-polyvinyl chloride.

(7) Ukubhoboza.

Ngaphansi kwesenzo sokucindezelwa okucindezelwayo kwezindlela ezintathu ezingalingani, okungenalutho kukhishwa emgodini noma igebe lesikhunta ukuze kuncishiswe indawo ephambanayo futhi kwandise ubude, futhi kube indlela yokucubungula yemikhiqizo edingekayo ebizwa ngokuthi i-extrusion. Ukucutshungulwa kwe-billet kubizwa ngokuthi i-pultrusion.

(8) Ukwakhiwa kweVacuum.

Ukwakhiwa kwe-vacuum ngokuvamile kubizwa ngokuthi i-blister. Isimiso esiyinhloko ukuthi ishidi lepulasitiki eliyisicaba liyashiswa futhi lithambile, bese limuncwa i-vacuum ebusweni besikhunta, futhi lakhiwe ngemva kokupholisa. Isetshenziswa kabanzi ekukhanyisweni kokufakwa kwepulasitiki, umhlobiso wokukhangisa nezinye izimboni.

(9) Ukubumba Okujikelezayo.

Ukubunjwa kwe-Roll kwaziwa nangokuthi i-rotary casting. Izinto zepulasitiki zengezwa esikhunjeni, esibe sesishisiswa ngokusizungeza ezimbazweni ezimbili eziqondile. Ngale ndlela, izinto zepulasitiki esikhunjeni kancane kancane futhi ngokulinganayo zinamathela kuyo yonke indawo yesikhunta ngaphansi kwesenzo samandla adonsela phansi namandla okushisa. Khona-ke, ukubumba ijamo elidingekayo, bese kuthi ngemva kokupholisa kuphothule ukwakhiwa, ekugcineni bathole imikhiqizo.

Okungenhla konke okuqukethwe kobuchwepheshe bokucubungula ipulasitiki, sicela uqhubeke nokunaka.
