I-Polyvinyl chloride (PVC) inamathisele i-Resin, njengoba negama lisho, ukuthi le resin isetshenziswa kakhulu kufomu lokunamathisela.Abantu bavame ukusebenzisa lolu hlobo lokunamathisela njenge-plastisol, okuwuketshezi oluyingqayizivele lwe-PVC yepulasitiki esimweni sayo esingacutshungulwanga..Ama-resin okunamathisela avame ukulungiswa nge-emulsion kanye nezindlela zokumisa ezincane.
I-Polyvinyl chloride paste resin inosayizi wezinhlayiyana ezinhle, futhi ukuthungwa kwayo kufana ne-talc, nokunganyakazi.I-polyvinyl chloride paste resin ixutshwa ne-Plasticizer bese inyakaziswa ukuze yakhe ukumiswa okuzinzile, okube sekwenziwa unamathisele we-PVC, noma i-PVC plastisol, i-PVC sol, futhi kungaleli fomu lapho abantu basetshenziselwa ukucubungula Imikhiqizo yokugcina.Enkambweni yokwenza unamathisele, ama-fillers ahlukahlukene, ama-diluents, ama-heat stabilizers, ama-foaming agents kanye neziqinisi ezikhanyayo zengezwa ngokuvumelana nezidingo zemikhiqizo ehlukene.
Ukuthuthukiswa kwemboni ye-PVC yokunamathisela resin inikeza uhlobo olusha lwezinto eziwuketshezi eziba umkhiqizo we-polyvinyl chloride ngokufudumeza kuphela.Lolu hlobo lwezinto eziwuketshezi kulula ukululungisa, luzinzile ekusebenzeni, lulawuleka kalula, lusebenziseka kalula, luhle kakhulu ekusebenzeni komkhiqizo, luhle ekuzinzeni kwamakhemikhali, lunamandla athile omshini, ukulufaka umbala kalula, njll., ngakho lusetshenziswa kabanzi. esikhumbeni sokwenziwa, amathoyizi e-vinyl, izimpawu zokuthengisa ezithambile, Ukukhiqizwa kwamaphephadonga, opende nezingubo zokumboza, amapulasitiki anegwebu, njll.
Isakhiwo:
I-PVC paste resin (PVC) iyisigaba esikhulu se-polyvinyl chloride resin.Uma kuqhathaniswa nama-resin amisiwe, iyimpushana ehlakazeka kakhulu.Ububanzi bosayizi wezinhlayiyana ngokuvamile bungu-0.1–2.0μm (ukusatshalaliswa kosayizi wezinhlayiyana zamarensi amisiwe ngokuvamile kungama-20–200μm. ).I-PVC yokunamathisela i-resin yacwaningwa efektri ye-IG Farben eJalimane ngo-1931, futhi ukukhiqizwa kwezimboni kwenziwa ngo-1937.
Engxenyeni yekhulu edlule, imboni yokunamathisela yomhlaba wonke ye-Pvc Resin ithuthuke ngokushesha.Ikakhulukazi kule minyaka eyishumi edlule, amandla okukhiqiza kanye nokuphumayo kubonise ukukhula okukhulu, ikakhulukazi e-Asia.Ngo-2008, umthamo womhlaba wonke wokukhiqiza wokunamathisela i-PVC resin wawucishe ube ngamathani ayizigidi ezi-3.742 ngonyaka, futhi umthamo ophelele wokukhiqiza e-Asia wawucishe ube ngamathani angu-918,000, okwenza u-24.5% wawo wonke umthamo wokukhiqiza.I-China iyisifunda esikhula ngokushesha embonini yokunamathisela ye-PVC resin, amandla okukhiqiza afinyelela cishe u-13.4% wesamba somthamo wokukhiqiza emhlabeni wonke kanye nama-57.6% wesamba somthamo wokukhiqiza e-Asia.Ingumkhiqizi omkhulu e-Asia.Ngo-2008, ukukhiqizwa komhlaba wonke kwenhlaka ye-PVC yokunamathisela kwakungamathani ayizigidi ezi-3.09, kanti okukhiqizwa e-China kwaba amathani angu-380,000, okwenza cishe u-12.3% womkhiqizo ophelele emhlabeni.Amandla okukhiqiza kanye nokuphumayo kukleliswe endaweni yesithathu emhlabeni.
