I-Polyvinyl Chloride (PVC) i-polymer eyenziwe yi-polymerization kaVinyl Chloride Momer (VCM) phambi kwabaQinisekiso njengePeroxides kanye ne-Azo Compounds noma yindlela yokusebenza kwama-polymerization wamahhala ngaphansi kwesenzo sokukhanya noma sokushisa. I-PVC iyisitayela se-polymer esisebenzisa i-athomu ye-chlorine ukufaka esikhundleni se-athomu le-hypythylene, kanye ne-vinyl chloride homopholymers kanye ne-vinyl chloride copolymers abizwa ngokuthi ama-vinyl chloride resendins.
Amaketanga ama-molecular ama-molecular aqukethe ama-athomu anamandla ama-athomu anamandla anamabutho aphezulu, okwenza imikhiqizo ye-PVC iqinile, i-flame retardancy (futhi ine-metact atransancy (i-flame retardancranic isho impahla ngemuva kokuthola ukubambezela kakhulu ukusakazeka kwelangabi); Kodwa-ke, amanani awo wokulahleka kwa-dielectric angle angle angela amakhulu kunalokho kwe-PE.
I-PVC Resin iqukethe inani elincane lama-bond ama-Double, amaketanga anezinhlangothi nezinsalela ze-athomu ezisele ezisele ezinhlangothini ze-polymerization, kanye nama-athomu ama-chlorhonen aphakathi kwama-pvc aphansi, okuholela ekuvuseleleni kahle kwe-PVC kalula ngaphansi kwesenzo sokukhanya nokushisa. Ngakho-ke, imikhiqizo ye-PVC idinga ukwengeza ukuqina kokushisa, njenge-calcium-zinc stabilizer, i-barium
Izicelo eziphambili
I-PVC iza ngezindlela ezahlukahlukene futhi ingacutshungulwa ngezindlela ezahlukahlukene, kufaka phakathi ukucindezela, ukuqeda, ukujova, nokugoqa. Ipulasitiki ye-PVC isetshenziswa kakhulu ekwenziweni kwamafilimu, isikhumba sokufakelwa, ukufakwa kwezintambo nezintambo, imikhiqizo eqinile, phansi, ifenisha, imishini yezemidlalo, njll.
Imikhiqizo ye-PVC ngokuvamile ihlukaniswa izigaba ezi-3: i-Gricid, Semi-Gridid futhi ithambile. Imikhiqizo eqinile futhi eqinile yenziwa ngaphandle noma ngenani elincane lepulasitiki, ngenkathi imikhiqizo ethambile icutshungulwa ngenani elikhulu lesesimo. Ngemuva kokungeza amapulasitiki, izinga lokushisa lengilazi lingahle kwehliswe, okwenza kube lula ukucubungula emazingeni okushisa aphansi futhi kwandise ukuguquguquka kanye noplastikimanyela kanye neplastiki ye-spatrity ye-chain molecular, futhi kwenze kube nokwenzeka ukwenza imikhiqizo ethambile eguquguqukayo ekushiseni kwegumbi.
1. Amaphrofayili we-PVC
Isetshenziselwa ikakhulukazi ukwenza iminyango kanye nezinto zokonga amandla nezinto zokonga amandla.
2. Amapayipi e-PVC
Amapayipi e-PVC anezinhlobo eziningi, ukusebenza okuhle kakhulu kanye nohlu olubanzi lokusebenzisa, futhi uthathe isikhundla esibalulekile emakethe.
3. Amafilimu we-PVC
I-PVC ingenziwa ibe yifilimu esobala noma enemibala yokubukhali okucacisiwe ngokusebenzisa ikhalenda, futhi ifilimu elikhiqizwa yile ndlela libizwa ngokuthi ifilimu elenziwe ngolwazi. Izinto zokwenziwa ze-PVC ze-granular ezingavuthiwe nazo zingashaywa zibe amafilimu zisebenzisa imishini yokubumba evuthayo, futhi ifilimu elikhiqizwa yile ndlela libizwa ngokuthi yi-blow yokuhlanganisa ifilimu. Ifilimu lingasetshenziselwa izinhloso eziningi futhi lingacutshungulwa libe yizikhwama, ama-raincoats, ama-tableccoths, amakhethini, amathoyizi angenakushibilika, njll ngokusika kokushisa nokusika kokushisa. Amafilimu abonakalayo akhulu asetshenziswa ukwakha ama-greenhouses kanye nezindawo zokugcina izithombo zepulasitiki, noma asetshenziswe njengamafilimu aphansi.
4. Ibhodi le-PVC
Kungezwe nge-Stabilizelizer, i-lubricant kanye ne-filler, nangemva kokuxutshwa, i-PVC ingakhishwa kumapayipi ahlukahlukene acwebile, amapayipi abunjiwe namapayipi ahlanzekile ane-extpor Amashidi anensimbi ahlanganiswe agcwele futhi ashise ukucindezelwa ukwenza amashidi aqinile obukhulu obuhlukahlukene. Amashidi angagawulwa abe bobunjwa olifunayo abese efakwe umoya oshisayo usebenzisa izinduku ezishisayo zisebenzisa izinduku zokufakelwa kwe-PVC zibe ngamathangi ahlukahlukene okugcina amakhemikhali, ama-ducts kanye neziqukathi, njll.
I-5. Imikhiqizo ethambile ye-PVC
Kusetshenziswa i-extruder, kungafakwa ku-hoses, izintambo, izintambo, njll.; Usebenzisa umshini wokubumba umjovo onobumba obuhlukahlukene, kungenziwa izimbadada zepulasitiki, izicathulo zezicucu, amathoyizi, amathoyizi, izingxenye ze-auto, njll.
I-6. I-PVC yokupakisha izinto
Imikhiqizo ye-PVC yokupakisha ikakhulukazi iziqukathi ezahlukahlukene, ifilimu nephepha elilukhuni. Iziqukathi ze-PVC zikhiqizwa ikakhulukazi amanzi amaminerali, iziphuzo, amabhodlela okugcoba, kodwa futhi nokupakishwa kwamafutha acwengisiwe.
7. I-PVC is a and flooring
I-PVC Siding isetshenziselwa ikakhulukazi ukufaka esikhundleni se-aluminium siding, amathayili we-PVC floor, ngaphandle kwengxenye ye-PVC resin, ezinye izakhi zezinto ezisetshenziswayo, anama-adhesive, ama-filler nezinye izingxenye zesikhumulo sezindiza nezinye izindawo ezinzima.
8. Imikhiqizo yabathengi be-PVC
Imikhiqizo ye-PVC ingatholakala yonke indawo empilweni yethu yansuku zonke. I-PVC isetshenziselwa ukwenza izimpaphe ezahlukahlukene zokufakelwa kwezikhwama zemithwalo, imikhiqizo yezemidlalo efana nama-basketball, amabhola ebhola kanye namabhola ombhoxo. Kusetshenziselwa futhi ukwenza umfaniswano kanye namabhande akhethekile wokuvikela. Izindwangu ze-PVC ze-Apparel zivame ukudonsa izindwangu (akukho makhompiyutha ezidingekayo) ezinjengePonchos, amabhulukwe wezingane, amajakethi wesikhumba okufakelwa kanye namabhuzu emvula ahlukahlukene. I-PVC nayo isetshenziswa emikhiqizweni eminingi yezemidlalo nasezintweni ezinjengamathoyizi, amarekhodi kanye nempahla yezemidlalo.
