Resin ea PVC
Ho na le mefuta e 4 ea Resin ea PVC e hlophisitsoeng ka mokhoa oa polymerization
1. Phatlalatso ea PVC ea ho emisoa
2. Emulsion Grade PVC
3. Bongata ba PVC ea Polymerised
4. Copolymer PVC
PVC ea ho emisoa
Mofuta o atileng haholo, Suspension grade PVC e entsoe ka marotholi a polymerizing a Vinyl Chloride monomer a emisitsoeng ka metsing.Ha Polymerization e phethiloe, slurry e centrifuged 'me kaka ea PVC e omisitsoe ka bonolo ke mekhoa e khethehileng ea ho futhumatsa e le hore e se ke ea beha resin e sa tsitsang ho senyeha ha mocheso.Boholo ba likaroloana tsa resin bo tloha ho li-micron tse 50-250 'me li na le li-popcorn tse nang le li-porous tse kang libopeho tse monyang Plasticisers habonolo.Sebopeho sa likaroloana tsa PVC se ka fetoloa ka ho khetha mahlahana a loketseng a ho emisa le Polymerization Catalyst.Mefuta e fokolang ea porous e sebelisoa haholo bakeng sa lisebelisoa tse phahameng tsa Rigid kapa tse sa entsoeng ka polasetiki tse kang PVC Pipes, Windows, Sidings, Ductings.Likarolo tse emisitsoeng tsa boholo ba karoloana e mahoashe le meaho e nang le masoba haholo e monya palo e kholo ea Plasticiser e etsang motsoako o ommeng mochesong o ka tlase ho 80oC. Mefuta e porous haholo e sebelisoa lits'ebetsong tsa Plasticised tse kang Cables, Footwear, Soft Calendered Sheeting le Films joalo-joalo.
Emulsion Grade PVC
Emulsion Polymerised PVC ke seo Paste Grade Resin e leng sona 'me sena se batla se sebelisoa feela bakeng sa Plastisols.Resin ea peista ke karoloana e ntle haholo ea PVC e hlahisoang ka ho omisa Emulsion ea PVC ka Metsing haholo joalo ka ha phofo ea lebese e hlahisoa.Resin ea boemo ba peista e hloka matla a mangata ho hlahisa 'me e theko e boima haholo ho feta Suspension resin.Resin ea sehlopha sa peista e na le lik'hemik'hale tse emulsifying le li-catalysts ka eona.Ka hona ha e hloeke ho feta Suspension Polymerized or Bulk Polymerized PVC.Thepa ea Motlakase ea Paste grade resin plastisols ka hona e futsanehile haholo ho feta Suspension Resin Compounds.Ho hlaka ho fokola ho feta Suspension kapa Bulk PVC.Resin ea sehlopha sa peista e kopane ka sebopeho, 'me ha e monye Plasticiser e ngata mochesong oa kamore.Lithempereichara tse fetang 160-180oC lia hlokahala ho khanna polasetiki ka har'a Resin nakong ea ho phekola.Paste grade Resin e sebelisoa haholo bakeng sa Cushion Vinyl Floorings ea bophara bo pharaletseng.Likarolo tse fapaneng tsa li-pastes tse entsoeng ka mokhoa o khethehileng li tlotsoa holim'a substrate e loketseng (Direct Coating) kapa Leqepheng la Release (Transfer coating).Likarolo li kopanngoa ka ho tsoelang pele ka liontong tse telele 'me li phuthoa ka mor'a hore pampiri ea tokollo e ntšoe.Mokato o motle oa fatše o ka ba le moaparo o thata oa semitransparent holim'a likarolo tse hatisitsoeng le tse phophomang tse lutseng holim'a lijase tse tlatsitsoeng haholo ho aha botenya.Litlamorao tse ngata tse khahlang haholo le tse ruileng lia khoneha 'me tsena li emela pheletso e phahameng ea Flooring ea Vinyl.
PVC e entsoeng ka bongata
Bulk Polymerisation e fana ka mofuta o hloekileng oa resin ea PVC kaha ha ho li-emulsifying kapa li-suspending agents tse sebelisoang.Li sebelisoa haholo-holo lits'ebetsong tse hlakileng.Li fumaneha haholo lihlopheng tse tlase tsa boleng ba K, kaha Liforomo tsa PVC tse sa Plastics for Blister Packaging le lifilimi tse ling tsa Calendered/Extruded Transparent li sebetsa hantle ho tsoa ho limaraka tse tlase tsa Boleng ba K.Lintlafatso tsa theknoloji ea Suspension resin li felisitse Bulk PVC nakong e fetileng.
Copolymer PVC
Vinyl Chloride e entsoe ka copolymerized ka li-comonomers tse kang Vinyl acetate e fana ka mefuta e mengata ea li-resin tse nang le thepa e ikhethang.PVAc kapa Copolymer ea Vinyl Chloride le Vinyl acetate ke ea bohlokoa ka ho fetisisa.Ho qhibiliha ho hotle ho solvents ea PVAc ho e etsa khetho ea mantlha bakeng sa li-inks tsa khatiso tsa Vinyl le disamente tse qhibilihang.Ho na le ts'ebeliso e ikhethang haholo ea PVAc ho Tiling ea Mokatong 'me ke resin ea khetho bakeng sa lithaele tsa Vinyl Asbestos.Resin ha e le hantle ke setlamo ho e-na le motsoako oa mantlha.Ka Copolymer Resin hoa khoneha ho etsa lithaelese tsa fatše ka Fillers joalo ka Asbestos le Calcium Carbonate accounting ea 84% ka Copolymer le li-additives tse ling tse kopanyang tse tlase ho 16%.Maemo a phahameng joalo ha a khonehe ka Suspension resin kaha viscosity ea eona e qhibilihisitsoeng e phahame haholo 'me ha e khone ho koahela le ho koahela maemo a phahameng joalo a inert filler.Ho hlokahala literene tse khethehileng bakeng sa lithaele tsa asbestos tsa Vinyl.Leha ho le joalo, kaha Asbestos e se e sa ratehe, lihlahisoa tse joalo li felile butle.
