I-PVC REIN YEKHEBULA
I-PVC REIN YEKHEBULA,
Inhlanganisela yekhebula le-PVC, I-PVC Cable Raw Material, I-PVC Yezintambo zikagesi, I-PVC resin yokufakelwa kwekhebula,
I-PVC ngoba inokusebenza okuhle ngokomzimba, kwamakhemikhali, kagesi, nokunqanda ilangabi, ngeminyaka yawo-1930s kanye nama-40s, i-PVC yangaphandle yaqala ukusebenzisa i-PVC ethambile njengezinto zokufakelwa kocingo, ukuthuthukiswa kanye nokusetshenziswa kwezinto zekhebula le-PVC ezweni lakithi kwaqala ngawo-1950.Ngokuthuthukiswa komthamo wokukhiqiza we-PVC resin, i-plasticizer kanye nezithasiselo zezimboni kanye nokukhuthazwa nokusebenzisa izinhlobo ezintsha, imboni yamakhebula inokweqa okufanelekile.
Ekhulwini lama-21, ngokuthuthukiswa kokuqwashisa kwabantu ngemvelo kanye nokunaka kwabantu impilo yabo siqu, izindaba zezemvelo seziphenduke umgomo womphakathi wesintu.Amazwe amaningi, izifunda nezinhlangano zenze izindinganiso nemithetho eqinile ukuze kukhawulwe ukusetshenziswa kwezinto eziyingozi, ikakhulukazi imithetho ye-RolS ne-REACH.Ukufuna izindlela ezintsha nezinqubo ezintsha, ukuthuthukisa izinga lokusebenzisa izinsiza, ukuzivumelanisa nezidingo zemithetho nemithethonqubo yokuvikela imvelo, ukuvikelwa kwemvelo kwezinto zekhebula le-PVC kwavela okwamanje, futhi ngokushesha kube enye yezindikimba zokuthuthukiswa kwezinto zekhebula le-PVC zamanje. .
Ushintsho olukhulayo kanye nokwanda kwesidingo semakethe socingo nekhebula (okubizwa ngokuthi ikhebula), kanye nocwaningo olunzulu lwezithasiselo ezintsha ezihlukahlukene (njengezithasiselo ezingabuthi amalangabi, ukucindezela intuthu), kugqugquzela ukukhuthazwa nokusetshenziswa kwezithasiselo ezintsha. ubuchwepheshe, izinto ezintsha kanye nemikhiqizo emisha yezinto PVC.Ngesamba esikhulu sezinto eziphilayo (ezifana nepulasitiki, irabha) esetshenziswa embonini yekhebula, inani lezinto zekhebula le-PVC liyinto yokuqala yezinto eziphilayo ezweni lethu.
I-thermoplastic high-molecular polymer eyenziwe yi-suspension polymerization ye-vinyl chloride monomer.I-molecular formula :- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500).Yimpahla eluhlaza esetshenziswa kabanzi ekukhiqizeni ipulasitiki.Inokuqina okuhle kwamakhemikhali, ukumelana nokugqwala nokumelana namanzi.
