isicelo

Ngenxa yokuthi i-pvc resin inokusebenza okuhle ngokomzimba, kwamakhemikhali, okukagesi, okuhoxisa 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 e-China kwaqala ngawo-1950s.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.

Izinto zekhebula le-PVC zakhiwe nge-polyvinyl chloride resin, i-stabilizer, i-plasticizer, i-filler, i-lubricant, i-antioxidant, i-colorant njalonjalo.

Ipulasitiki ye-PVC ngenxa yokuvutha kwayo, ukumelana nowoyela, ukumelana ne-corona, ukumelana nokugqwala kwamakhemikhali nokumelana okuhle namanzi, ngakho isetshenziswa kabanzi njengento yokuvikela izintambo nezintambo.Ngokungeza izithasiselo zokusebenza ezikhethekile noma izilungisi, ukumelana nokushisa (105℃), ukumelana nokubanda, ukumelana nowoyela, ukumelana nelangabi, izinto zekhebula le-PVC ezithambile nezingezona ubuthi zingakhiqizwa ngokulandelana kwazo ukuze kuhlangatshezwane nezidingo zemikhiqizo yezintambo ezikhethekile nezintambo.

Ngokungeza izithasiselo zokusebenza ezikhethekile noma izilungisi, ukumelana nokushisa (105℃), ukumelana nokubanda, ukumelana nowoyela, ukumelana nelangabi, izinto zekhebula le-PVC ezithambile nezingezona ubuthi zingakhiqizwa ngokulandelana kwazo ukuze kuhlangatshezwane nezidingo zemikhiqizo yezintambo ezikhethekile nezintambo.

Ipulasitiki ye-Polyvinyl chloride (PVC) iyipulasitiki enezingxenye eziningi, ngokusho kwezimo ezihlukene zokusetshenziswa, ngokushintsha izinhlobonhlobo kanye nomthamo we-ejenti eyinkimbinkimbi, ingenziwa ngezinhlobo ezahlukene zepulasitiki ye-PVC yocingo nekhebula.Ipulasitiki yekhebula ye-Polyvinyl chloride (PVC) ngokuya ngokusetshenziswa kwayo ocingweni nakwikhebula, ingahlukaniswa ngokwezinto zekhebula lezinga lokufakwa kanye nezinto zekhebula lezinga lokuvikela.Izinga lokuvikela lidinga ukumelana nokushisa okuhle, futhi izinga lokufakwa kwe-insulation lidinga ukufakwa kahle.

Sebenzisa ukuhlukanisa

Izinto zekhebula le-PVC zingahlukaniswa zibe:

I-PVC insulated cable material

PVC sheathed ikhebula impahla

Izinto zekhebula ezivale amalangabi ze-PVC ezivale amalangabi

I-PVC enekhebula le-Flame retardant

Izinto zekhebula le-PVC elastomer

Ikhebula le-PVC elingaphandle elingaphandle elingaphakathi
