I-PVC Resin
Kukho iintlobo ezi-4 zePVC Resin ezidityaniswe ngendlela yepolymerization
1. Ukumiswa kweBanga lePVC
2. Emulsion Grade PVC
3. Ubuninzi bePVC yePolymerised
4. I-PVC ye-Copolymer
Ukumiswa kweBanga lePVC
Olona hlobo luxhaphake kakhulu, iPVC yenqanaba lokuSuspension yenziwa ngamathontsi epolymerizing eVinyl Chloride monomer exhonywe emanzini.Xa i-Polymerization igqityiwe, i-slurry i-centrifuged kwaye ikhekhe le-PVC yomiswe ngobunono ngeenkqubo zokufudumeza ezikhethekileyo ukwenzela ukuba ingabi phantsi kwe-resin engazinzanga ekuthotyweni kobushushu.Ubungakanani be-particle ye-resin iqala kwi-50-250 microns kwaye ine-popcorn ene-porous efana nezakhiwo ezifunxa ngokulula iiPlastiki.Ukwakhiwa kweengqungquthela zePVC zinokuguqulwa ngokukhetha i-agent efanelekileyo yokumisa kunye nePolymerisation Catalyst.Iintlobo ze-porous ezingaphantsi zisetyenziswa kakhulu kumthamo ophezulu we-PVC oqinileyo okanye ongafakwanga iplastiki njengeMibhobho yePVC, iiWindows, iiSidings, iiDuctings.Amabanga okunqunyanyiswa obungakanani besuntswana elirhabaxa kunye nezakhiwo ezinarhaxa kakhulu zifunxa ubungakanani obukhulu bePlastiki eyenza umxube owomileyo kumaqondo obushushu angaphantsi kwama-80oC.Iintlobo zeporous ezingaphezulu zisetyenziswa kwizicelo zePlastiki ezifana neeCables, Footwear, Soft Calendared Sheeting kunye neeFilimu njl.
Emulsion Grade PVC
I-Emulsion Polymerised PVC yinto eNcamathelisa iBanga leResin kwaye oku kuphantse kusetyenziswe iiPlastisols kuphela.Ncamathisela intlaka ibakala yisuntswana entle kakhulu ubukhulu PVC eveliswe ngokutshiza ukomisa i Emulsion of PVC e Amanzi kakhulu ngathi ubisi umgubo uveliswa.I-resin yomgangatho wokucola ifuna amandla amaninzi ukuyivelisa kwaye ibiza kakhulu kune-Suspension resin.I-resin ye-paste grade resin ithwala iikhemikhali ze-emulsifying kunye ne-catalysts kunye nayo.Ngoko ke ayisulungeki kangako kune-Suspension Polymerized or Bulk Polymerized PVC.Iipropathi zoMbane ze-Plastisols ze-resin zebakala ke ngoko zihlwempuzeke kakhulu kuneeCompounds zokuSuspension Resin.Ukucaca kuhlwempuzekileyo kunoKunqunyanyiswa okanye uBuninzi bePVC.Intlaka yentlaka yeNcamathelisa i-compact kwisakhiwo, kwaye ayifunxi kakhulu iPlastiki kubushushu begumbi.Amaqondo obushushu angaphezu kwe-160-180oC ayadingeka ukuqhuba iplastiki kwi-Resin ngexesha lokunyanga.I-Resin yomgangatho wokucola isetyenziswa kakhulu kwiCushion Vinyl Floorings yobubanzi obubanzi.Iileya ezahlukeneyo zeepasti ezenziwe ngokukodwa ziqatywe okanye kwi-substrate efanelekileyo (i-Direct Coating) okanye kwiPhepha lokuKhupha (i-Transfer coating).Amaleko adityaniswa ngokuqhubekayo kwii-oveni ezinde kwaye asongwe emva kokuba iphepha lokukhulula likhutshiwe.Umgangatho osongiweyo olungileyo unokuba noqweqwe oluqinileyo lwe-semitransparent ngaphezulu kweeleya eziprintiweyo kunye ezinogwebu ezihleli phezu kweedyasi ezigcwele kakhulu ukuze zakhe ubukhulu.Uninzi lweziphumo ezinomtsalane kakhulu kunye nezityebileyo zinokwenzeka kwaye ezi zimele isiphelo esiphezulu seVinyl Flooring.
Ubuninzi bePVC yePolymerised
I-Bulk Polymerisation inika eyona ndlela icocekileyo ye-PVC resin njengoko kungekho zixhobo zokumisa okanye zokumisa zisetyenziswa.Zisetyenziswa ikakhulu kwizicelo ezingafihliyo.Ikakhulu zenziwe zifumaneke kumaqela asezantsi exabiso le-K, njengeeFoil zePVC ezingafakwanga zePVC zeBlister Packaging kunye nezinye iifilimu zeCalendered/Extruded Transparent zezona zicutshungulwayo ukusuka kumabakala asezantsi eXabiso le-K.Uphuculo kwitekhnoloji ye-resin ye-Suspension ikhuphe i-Bulk PVC kwixa elidlulileyo.
Copolymer PVC
I-Vinyl Chloride i-copolymerized kunye ne-comonomers efana ne-acetate ye-Vinyl inika uluhlu lwee-resin ezineempawu ezizodwa.I-PVAc okanye iCopolymer yeVinyl Chloride kunye neVinyl acetate yeyona nto ibalulekileyo.Ukunyibilika okulungileyo kwizinyibilikisi zePVAc kuyenza ibe lolona khetho luphambili kwiVinyl Printing Inks kunye nesamente ezinyibilikayo.Kukho usetyenziso olukhethekileyo lwePVAc ekufakweni kwethayile kuMgangatho kwaye yiresin ekhethwayo kwiithayile zeVinyl Asbestos.I-Resin eneneni sisibophelelo kunesona sithako siphambili.NgeCopolymer Resin kuyenzeka ukwenza iithayile zomgangatho kunye neziFakelo ezifana neAsbestos kunye neCalcium Carbonate accounting ukuya kuthi ga kwi-84% ngeCopolymer kunye nezinye izongezo ezidityanisiweyo ezisezantsi nge-16%.Amanqanaba aphezulu anjalo awanakwenzeka nge-Suspension resin njengoko i-viscosity yayo yokunyibilika iphezulu kakhulu kwaye ayinakukwazi ukugquma kwaye ifake amanqanaba aphezulu e-inert filler.Izitimela ezikhethekileyo zokufowunela ziyafuneka kwiithayile zeasbestos zeVinyl.Nangona kunjalo nge-asbestos ephumayo, iimveliso ezinjalo ziye zaphela kancinci.
