Enziwa Kanjani Amapayipi e-PVC?,
Ibanga le-PVC lepayipi, I-PVC Pipe Raw Material,
I-PVC isifinyezo se-polyvinyl chloride.I-resin yinto evame ukusetshenziswa ekukhiqizeni amapulasitiki namarabha.I-PVC resin iyimpushana emhlophe evame ukusetshenziselwa ukukhiqiza i-thermoplastics.Yimpahla yokwenziwa esetshenziswa kabanzi emhlabeni namuhla.I-Polyvinyl chloride resin inezici ezivelele njengokuchichima kwezinto zokusetshenziswa, ubuchwepheshe bokukhiqiza obuvuthiwe, intengo ephansi, kanye nenhlobonhlobo yokusetshenziswa.Kulula ukucubungula futhi ingacutshungulwa ngokubumba, i-laminating, ukubunjwa komjovo, i-extrusion, i-calendering, i-blow molding nezinye izindlela.Ngezakhiwo ezinhle zomzimba namakhemikhali, isetshenziswa kabanzi embonini, kwezokwakha, ezolimo, empilweni yansuku zonke, ekupakishayo, ugesi, izinsiza zomphakathi, nakweminye imikhakha.Ama-resin e-PVC ngokuvamile anokumelana namakhemikhali aphezulu.Inamandla kakhulu futhi imelana namanzi nokuhuzuka.I-Polyvinyl chloride resin (PVC) ingacutshungulwa ibe yimikhiqizo ehlukahlukene yepulasitiki.I-PVC iyipulasitiki engasindi, engabizi, futhi enobungani bemvelo.I-Pvc Resin ingasetshenziswa kumapayipi, amafreyimu amafasitela, amapayipi, izikhumba, izintambo zocingo, izicathulo kanye neminye imikhiqizo ethambile evamile, amaphrofayili, okokufakwayo, amaphaneli, umjovo, ukubumba, izimbadada, ishubhu eliqinile nezinto zokuhlobisa, amabhodlela, amashidi, ikhalenda, umjovo oqinile kanye nokubunjwa, njll nezinye izingxenye.
Izici
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanye nesikhumba sokwenziwa, ngokwengeza ama-plasticizers.

Isicelo
Amapayipi e-PVC akhiqizwa nge-extrusion ye-PVC yempahla eluhlaza, futhi ngokuvamile alandela izinyathelo ezifanayo zemisebenzi evamile yokukhipha amapayipi:
Ukuphakelwa kwama-pellets/impushana yezinto ezingavuthiwe ku-PVC twin screw extruder
Ukuncibilika nokushisisa ezindaweni eziningi ze-extruder
Ukukhipha idayizi ukuze kube ipayipi
Ukupholisa kwepayipi elimise
Ukusika amapayipi e-PVC ubude obufunayo
Kodwa-ke, naphezu kokuba nenqubo yokukhiqiza efanayo kumapayipi amaningi epulasitiki, amapayipi e-PVC anezici zangaphakathi ezibeka izinselelo ezengeziwe kubakhiqizi bamapayipi kokubili ngokokukhiqiza, kanye nokubeka imikhiqizo yabo emakethe.
