Nkwusioru ọkwa PVC
Ụdị kachasị ewu ewu, PVC ọkwa nkwusioru bụ site na polymerizing ụmụ irighiri mmiri nke Vinyl Chloride monomer kwụsịtụrụ na mmiri.Mgbe Polymerisation zuru ezu, slurry bụ centrifuged na achicha PVC na-eji nwayọọ kpoo ya site na usoro kpo oku pụrụ iche ka ọ ghara idobe resin na-adịghị edozi ahụ ka ọ ghara ikpo ọkụ.Ogo urughuru resin sitere na 50-250 microns ma nwee porous popcorn dị ka ihe owuwu nke na-amịkọrọ Plasticisers ngwa ngwa.Enwere ike ịmegharị ihe owuwu nke ihe ndị dị na PVC site na ịhọrọ ndị ọrụ nkwụsịtụ kwesịrị ekwesị na Polymerisation Catalyst.A na-eji ụdị porous pere mpe nke ukwuu maka ngwa PVC siri ike ma ọ bụ nke enweghị mkpuchi dị ka PVC ọkpọkọ, Windows, Sidings, Ductings.Nkwusioru akara ule nke a coarser urughuru size na nnọọ porous owuwu banye nnukwu quantities nke Plasticiser akpụ a dryblend na okpomọkụ dị ka ala dị ka 80oC.The ọzọ porous ụdị na-eji na Plasticised ngwa dị ka Cables, Footwear, Soft Calendered Sheeting na Films wdg.
Emulsion ọkwa PVC
Emulsion Polymerised PVC bụ ihe Tapawa Grade Resin bụ nke a na-eji naanị maka Plastisols.Tapawa ọkwa resin bụ ezigbo urughuru nha PVC nke a na-emepụta site na ịsasa ihe emulsion nke PVC na mmiri dị ka esi esi emepụta ntụ ntụ mmiri ara ehi.Tapawa resin ọkwa chọrọ ike ka ukwuu iji mepụta ma dị oke ọnụ karịa resin nkwusioru.Resin ọkwa tapawa na-ebu kemịkalụ emulsifying ma na-akpali ya.Ya mere ọ dịchaghị ọcha karịa nkwusioru Polymerized ma ọ bụ nnukwu polymerized PVC.Ngwongwo eletriki nke Paste grade resin plastisols bụ ya mere dara ogbenye karịa nkwusioru Resin Compounds.Ịdị ọcha dị njọ karịa nkwusioru ma ọ bụ nnukwu PVC.Tapawa ọkwa resin bụ kọmpat na nhazi ya, ọ naghị amịkọrọ Plasticiser na okpomọkụ nke ụlọ.Okpomọkụ karịrị 160-180oC dị mkpa iji buba plasticer n'ime resin n'oge ọgwụgwọ.A na-eji resin ọkwa tapawa nke ukwuu maka ala ala Kushion Vinyl nke obosara obosara.A na-ekpuchi akwa dị iche iche nke pastes a haziri ahazi ma ọ bụ na mkpụrụ kwesịrị ekwesị (nkpuchi ozugbo) ma ọ bụ na akwụkwọ mwepụta (nkpuchi mbufe).A na-ejikọta akwa ndị ahụ na-aga n'ihu na oven dị ogologo ma tụgharịa mgbe ewepụsịrị akwụkwọ ntọhapụ.Ọmarịcha ala a na-agbagharị agbagharị nwere ike ịnwe akwa akwa siri ike semitransparent n'elu akwa ebipụta na ụfụfụ nke na-anọdụ ala n'elu uwe elu jupụtara nke ukwuu iji wulite ọkpụrụkpụ.Ọtụtụ mmetụta mara mma na nke bara ụba ga-ekwe omume ma ndị a na-anọchite anya njedebe dị elu nke vinyl Flooring.
PVC polymerised buru ibu
Nnukwu Polymerisation na-enye ụdị resin PVC kachasị dị ọcha n'ihi na ọ dịghị emulsifying ma ọ bụ ihe nkwụsịtụ na-eji.A na-ejikarị ha eme ihe na ngwa ngwa.A na-eme ya ka ọ dị na obere uru K dị ala, dị ka ihe mkpuchi PVC na-adịghị edozi maka nkwakọ ngwaahịa blister na ihe nkiri ndị ọzọ Calendered/Extruded transparent ka a na-ahazi nke ọma site na akara akara K bara uru.Ntucha na teknụzụ resin nkwusioru ewepụla nnukwu PVC n'oge gara aga.
Copolymer PVC
Vinyl Chloride bụ copolymerized na comonomers dị ka Vinyl acetate na-enye ọtụtụ resins nwere ihe pụrụ iche.PVAc ma ọ bụ Copolymer nke Vinyl Chloride na Vinyl acetate bụ ihe kacha mkpa.Ezigbo solubility na ihe mgbaze nke PVac na-eme ka ọ bụrụ nhọrọ kachasị maka Vinyl Printing Inks na cement ihe mgbaze.Enwere ngwa PVAc pụrụ iche na tile ụlọ na ọ bụ resin nke oke maka taịlị Asbestos Vinyl.Resin bụ n'ezie ihe nkedo kama ịbụ isi ihe.Site na Copolymer Resin, ọ ga-ekwe omume ịmepụta taịlị ala na Fillers dị ka Asbestos na Calcium Carbonate na-aza ihe ruru 84% na Copolymer na mgbakwunye mgbakwunye ndị ọzọ dị ala dị ka 16%.Ọkwa dị elu dị otú ahụ agaghị ekwe omume na resin nkwusioru n'ihi na viscosity ya gbazere dị elu nke ukwuu na enweghị ike mkpuchi mkpuchi ma kpuchie ọkwa dị elu nke inert filler.A chọrọ ụgbọ oloko oku pụrụiche maka taịlị asbestos Vinyl.Agbanyeghị na Asbestos na-adaba na ihu ọma, ngwaahịa ndị dị otú ahụ ejirila nwayọọ nwayọọ nwụọ.
