I-Polyvinyl chloride (i-PVC) i-polymer eyenziwe yi-polymerization ye-vinyl chloride monomer (VCM) phambi kwee-initiators ezifana ne-peroxides kunye ne-azo compounds okanye ngendlela ye-polymerization yamahhala phantsi kwesenzo sokukhanya okanye ubushushu. I-PVC yimathiriyeli ye-polymer esebenzisa i-athomu ye-chlorine ukuze ithathe indawo ye-athomu ye-hydrogen kwi-polyethylene, kunye ne-vinyl chloride homopolymers kunye ne-vinyl chloride copolymers ngokudibeneyo zibizwa ngokuba yi-vinyl chloride resins.
Amatsheyina emolekyuli ePVC aneeathom zeklorini epholileyo enamandla anamandla aphezulu e-intermolecular, ezenza iimveliso ze-PVC zibe ngqongqo, ziqine, kwaye zivakale ngoomatshini, kwaye zibe nokulibaziseka okugqwesileyo kwedangatye (ukubuyiswa komlilo kubhekiselele kwipropathi enayo into okanye into enayo emva konyango. ukulibazisa kakhulu ukusasazeka komlilo); nangona kunjalo, amaxabiso e-dielectric ahlala kunye ne-dielectric loss angle tangent inkulu kune-PE.
I-resin ye-PVC iqulethe inani elincinci leebhondi eziphindwe kabini, i-branched chain kunye ne-initiator intsalela eshiywe kwi-polymerization reaction, kunye ne-chlorine kunye ne-athomu ye-hydrogen phakathi kwee-athom zekhabhoni ezimbini ezikufutshane, ezikhutshwa ngokulula, ezikhokelela ekuphenduleni ukuthotywa kwe-PVC ngokulula phantsi kwesenzo. yokukhanya nobushushu. Ngoko ke, iimveliso ze-PVC kufuneka zongeze izizinzi zobushushu, ezifana ne-calcium-zinc stabilizer, i-barium-zinc stabilizer, isizinzi sobushushu betyuwa, i-organic tin stabilizer, njl.
Usetyenziso oluphambili
I-PVC iza ngeendlela ezahlukeneyo kwaye ingalungiswa ngeendlela ezahlukeneyo, kuquka ukucofa, ukukhupha, ukutofa, kunye nokwaleka. Iiplastiki zePVC zidla ngokusetyenziswa xa kusenziwa iifilimu, ngethwathwa, ukugqunywa kweengcingo kunye neentambo, iimveliso eziqinileyo, umgangatho, ifenitshala, izixhobo zemidlalo, njl.
Iimveliso ze-PVC zihlelwa ngokubanzi zibe ziindidi ezi-3: lukhuni, lukhuni, kwaye zithambile. Iimveliso eziqinileyo kunye ne-semi-rigid zicutshungulwa ngaphandle okanye nge-plasticizer encinci, ngelixa iimveliso ezithambileyo zicutshungulwa ngexabiso elikhulu leplastiki. Emva kokongeza i-plasticizers, iqondo lokushisa lokuguqulwa kweglasi linokuthotywa, okwenza kube lula ukucubungula kwiqondo lokushisa eliphantsi kunye nokwandisa ukuguquguquka kunye neplastiki yekhonkco ye-molecular, kwaye yenza kube lula ukwenza iimveliso ezithambileyo eziguquguqukayo kwiqondo lokushisa.
1. Iiprofayili zePVC
Ikakhulu isetyenziselwa ukwenza iingcango kunye neefestile kunye nezinto ezigcina amandla.
2. Imibhobho yePVC
Imibhobho ye-PVC ineentlobo ezininzi, ukusebenza okugqwesileyo kunye noluhlu olubanzi lokusetyenziswa, kwaye ithatha indawo ebalulekileyo kwimarike.
3. Iifilimu zePVC
I-PVC inokwenziwa ifilimu ecacileyo okanye enemibala yobukhulu obuchaziweyo ngokusebenzisa ikhalenda, kwaye ifilimu eveliswa ngale ndlela ibizwa ngokuba yifilimu yekhalenda. Izixhobo zePVC zegranular zinokuvuthelwa zibe yifilim kusetyenziswa oomatshini bokubumba, kwaye ifilimu eveliswe yile ndlela ibizwa ngokuba yiblow Molding film. Ifilimu ingasetyenziselwa iinjongo ezininzi kwaye inokucutshungulwa kwiingxowa, i-raincoats, i-tablecloths, amakhethini, amathoyizi ane-inflatable, njl. ngokusika kunye neendlela zokuvala ukushisa. Iifilimu ezicacileyo ezibanzi zingasetyenziselwa ukwakha izindlu zokugcina izityalo kunye nezindlu zokugcina izityalo zeplastiki, okanye zisetyenziswe njengeefilimu zomgangatho.
4. ibhodi yePVC
Ukongezwa kunye ne-stabilizer, i-lubricant kunye ne-filler, kwaye emva kokuxuba, i-PVC inokukhutshwa kwiipayipi ezahlukeneyo ze-caliber, iipayipi ezimile kunye ne-corrugated pipes kunye ne-extruder, kwaye isetyenziswe njenge-downpipe, umbhobho wamanzi okusela, i-casing yombane yombane okanye i-staircase handrail. Amaphepha e-calender agqithene kwaye ashushu acinezelwe ukwenza amacwecwe aqinileyo obunzima obahlukeneyo. Amaphepha anokusikwa abe ziimilo ezinqwenelekayo kwaye emva koko adityaniswe ngomoya oshushu kusetyenziswa i-PVC welding rods zibe ngamatanki okugcina amelana neekhemikhali, imibhobho kunye nezikhongozeli, njl.
5. Iimveliso ezithambileyo zePVC
Ukusebenzisa i-extruder, inokukhutshelwa kwi-hoses, iintambo, iingcingo, njl.; usebenzisa umatshini wokubumba wenaliti onezinto ezahlukeneyo zokubumba, unokwenziwa kwiimbadada zeplastiki, izihlangu zezihlangu, i-slippers, iithoyi, iinxalenye zemoto, njl.
6. Izinto zokupakisha zePVC
Iimveliso zePVC zokupakishwa ikakhulu kwiibhotile ezahlukeneyo, ifilimu kunye nephepha elilukhuni. Izikhongozeli zePVC ziveliswa ikakhulu kumanzi amaminerali, iziselo, iibhotile zokuthambisa, kodwa kunye nokupakishwa kweoyile esulungekileyo.
7. PVC siding kunye nomgangatho
I-PVC siding isetyenziselwa ukutshintsha i-aluminium siding, iithayile zomgangatho we-PVC, ngaphandle kwenxalenye ye-PVC ye-resin, amanye amacandelo zizinto ezihlaziyiweyo, izinto zokuncamathelisa, izihluzi kunye namanye amacandelo, ikakhulu asetyenziswa kwisikhululo seenqwelomoya umgangatho kunye nezinye iindawo ezinzima. umhlaba.
8. Iimveliso zabathengi bePVC
Iimveliso zePVC zinokufumaneka kuyo yonke indawo kubomi bethu bemihla ngemihla. I-PVC isetyenziselwa ukwenza iindidi ezahlukeneyo zesikhumba ezenziweyo kwiingxowa zemithwalo, iimveliso zemidlalo ezifana nebhola yomnyazi, iibhola zesoka kunye neebhola zombhoxo. Ikwasetyenziselwa ukwenza iiyunifomu kunye namabhanti ezixhobo ezikhethekileyo zokukhusela. Amalaphu e-PVC esinxibo adla ngokufunxa amalaphu (akukho ngubo ifunekayo) njengeponcho, ibhulukhwe yomntwana, iibhatyi ezenziweyo zesikhumba kunye neebhutsi zemvula ezahlukeneyo. I-PVC ikwasetyenziswa kwimidlalo emininzi kunye neemveliso zokuzonwabisa ezifana neethoyi, iirekhodi kunye nempahla yezemidlalo.
