I-Polyvinyl chloride (PVC) iyi-polymer eyenziwe yi-polymerization ye-vinyl chloride monomer (VCM) phambi kweziqalisi ezifana nama-peroxides nama-azo compounds noma ngomshini we-polymerization yamahhala ngaphansi kwesenzo sokukhanya noma ukushisa. I-PVC iyi-polymer material esebenzisa i-athomu ye-chlorine esikhundleni se-athomu ye-hydrogen ku-polyethylene, futhi ama-vinyl chloride homopolymers nama-vinyl chloride copolymers ngokuhlangene abizwa ngokuthi ama-vinyl chloride resins.
Amaketanga e-PVC amangqamuzana aqukethe ama-athomu e-chlorine e-polar anamandla amakhulu e-intermolecular, okwenza imikhiqizo ye-PVC iqine kakhudlwana, iqine, futhi izwakale ngomshini, futhi ibe nokuhlehla kwelangabi okuhle kakhulu (ukuhlehla kwelangabi kubhekisela endaweni into enayo noma into ethile enayo ngemva kokwelashwa. ukubambezela kakhulu ukusakazeka komlilo); Nokho, amanani ayo e-dielectric engaguquki kanye ne-dielectric loss angle tangent makhulu kunalawo e-PE.
I-PVC resin iqukethe inani elincane lamabhondi aphindwe kabili, amaketanga anamagatsha kanye nezinsalela zokuqalisa ezisele ekuphenduleni kwe-polymerization, kanye nama-athomu e-chlorine ne-hydrogen phakathi kwama-athomu ekhabhoni amabili ancikene, akhishwa kalula i-chlorine, okuholela ekuphenduleni kokuwohloka kwe-PVC kalula ngaphansi kwesenzo. yokukhanya nokushisa. Ngakho-ke, imikhiqizo ye-PVC idinga ukungeza iziqinisi zokushisa, ezifana ne-calcium-zinc heat stabilizer, i-barium-zinc heat stabilizer, i-lead salt heat stabilizer, i-organic tin stabilizer, njll.
Izinhlelo zokusebenza eziyinhloko
I-PVC iza ngezinhlobo ezahlukene futhi ingacutshungulwa ngezindlela ezahlukene, okuhlanganisa ukucindezelwa, ukukhipha, ukujova, nokuhlanganisa. Amapulasitiki e-PVC avame ukusetshenziswa ekwenzeni amafilimu, isikhumba sokwenziwa, ukufakwa kwezintambo nezintambo, imikhiqizo eqinile, i-flooring, ifenisha, imishini yezemidlalo, njll.
Imikhiqizo ye-PVC ngokuvamile ihlukaniswa ngezigaba ezi-3: eqinile, eqinile kancane futhi ethambile. Imikhiqizo eqinile futhi eqinile icutshungulwa ngaphandle noma ngenani elincane le-plasticizer, kuyilapho imikhiqizo ethambile icutshungulwa ngenani elikhulu le-plasticizer. Ngemva kokwengeza ama-plasticizers, izinga lokushisa lokuguqulwa kwengilazi lingancishiswa, okwenza kube lula ukucubungula ekushiseni okuphansi futhi kwandise ukuguquguquka kanye ne-plasticity yeketanga lamangqamuzana, futhi kwenza kube nokwenzeka ukwenza imikhiqizo ethambile eguquguqukayo ekamelweni lokushisa.
1. Amaphrofayili e-PVC
Isetshenziselwa kakhulu ukwenza iminyango namafasitela nezinto zokonga amandla.
2. PVC amapayipi
Amapayipi e-PVC anezinhlobonhlobo eziningi, ukusebenza okuhle kakhulu kanye nohlu olubanzi lokusetshenziswa, futhi athatha isikhundla esibalulekile emakethe.
3. Amafilimu e-PVC
I-PVC ingenziwa ibe ifilimu esobala noma enombala enogqinsi olucacisiwe ngokusebenzisa ikhalenda, futhi ifilimu ekhiqizwa ngale ndlela ibizwa ngokuthi ifilimu ye-calendered. I-PVC granular raw ingaphinde ivuthelwe ibe yifilimu kusetshenziswa imishini yokubumba i-blow, futhi ifilimu ekhiqizwa ngale ndlela ibizwa ngokuthi i-blow molding film. Ifilimu ingasetshenziselwa izinhloso eziningi futhi ingacutshungulwa ibe yizikhwama, ama-raincoat, izindwangu zetafula, amakhethini, amathoyizi aphefumulayo, njll ngokusika kanye nezindlela zokuvala ukushisa. Amafilimu abanzi asobala angasetshenziswa ukwakha izindlu zokugcina izithombo nezindawo zokugcina izithombo zepulasitiki, noma asetshenziswe njengamafilimu aphansi.
4. Ibhodi le-PVC
Ingezwe nge-stabilizer, i-lubricant kanye ne-filler, futhi ngemva kokuxuba, i-PVC ingadluliselwa kumapayipi ahlukahlukene aqinile, amapayipi amise okwezimo kanye namapayipi kathayela ane-extruder, futhi asetshenziswe njengepayipi eliphansi, ipayipi lamanzi okuphuza, i-electric wire casing noma i-staircase handrail. Amashidi ane-calender agqagqana futhi acindezelwe ashisayo ukuze enze amashidi aqinile anobukhulu obuhlukahlukene. Amashidi angasikwa abe yizimo ezifunwayo bese eshiselwa ngomoya oshisayo kusetshenziswa izinduku zokushisela ze-PVC zibe amathangi okugcina amelana namakhemikhali, imigudu neziqukathi, njll.
5. Imikhiqizo ethambile ye-PVC
Ukusebenzisa i-extruder, ingakhishwa ibe ngamapayipi, izintambo, izintambo, njll.; usebenzisa umshini wokubumba umjovo onesikhunta esihlukahlukene, ungenziwa izimbadada zepulasitiki, izicathulo zezicathulo, ama-slippers, amathoyizi, izingxenye zezimoto, njll.
6. Izinto zokupakisha ze-PVC
Imikhiqizo ye-PVC yokupakishwa ikakhulukazi yezinhlobonhlobo zeziqukathi, ifilimu neshidi eliqinile. Iziqukathi ze-PVC zikhiqizwa ikakhulukazi amanzi amaminerali, iziphuzo, amabhodlela ezimonyo, kodwa futhi nokupakishwa kwamafutha acolisisiwe.
7. PVC siding kanye flooring
I-PVC siding isetshenziselwa kakhulu ukufaka esikhundleni se-aluminium siding, amathayela aphansi we-PVC, ngaphandle kwengxenye ye-PVC resin, zonke ezinye izingxenye ziyizinto ezigaywe kabusha, izinto zokunamathisela, izigcwalisi nezinye izinto, ezisetshenziswa kakhulu endaweni yesikhumulo sezindiza nakwezinye izindawo eziqinile. phansi.
8. Imikhiqizo yabathengi be-PVC
Imikhiqizo ye-PVC ingatholakala yonke indawo ekuphileni kwethu kwansuku zonke. I-PVC isetshenziselwa ukwenza izikhumba zokwenziwa ezihlukahlukene zezikhwama zemithwalo, imikhiqizo yezemidlalo efana ne-basketballs, amabhola ebhola kanye namabhola ebhola lombhoxo. Ibuye isetshenziselwe ukwenza imifaniswano namabhande emishini ekhethekile yokuzivikela. Izindwangu ze-PVC zezingubo ngokuvamile ziyizindwangu ezimuncayo (akukho ukunamathela okudingekile) njengama-poncho, amabhulukwe ezingane, amajakhethi esikhumba okwenziwa kanye namabhuzu emvula ahlukahlukene. I-PVC iphinde isetshenziswe emikhiqizweni eminingi yezemidlalo nezokuzijabulisa njengamathoyizi, amarekhodi kanye nezimpahla zezemidlalo.
