PVC Resin
Hariho ubwoko 4 bwa PVC Resin yashyizwe hamwe nuburyo bwa polymerisation
1. Icyiciro cyo guhagarika PVC
2. Icyiciro cya Emulsion PVC
3. PVC nyinshi
4. Copolymer PVC
Icyiciro cyahagaritswe PVC
Ubwoko bwiganje cyane, PVC yo guhagarikwa ikorwa na polymerizing ibitonyanga bya Vinyl Chloride monomer yahagaritswe mumazi.Iyo Polymerisation irangiye, ibishishwa bishyirwa hamwe hanyuma cake ya PVC ikumishwa buhoro na sisitemu idasanzwe yo gushyushya ibintu kugirango idaterwa nubutaka butajegajega kugirango ubushyuhe bwangirike.Ingano yubunini bwa resin iri hagati ya microne 50-250 kandi ifite popcorn yuzuye nkibikoresho byakira byoroshye Plastisiseri.Imiterere yibice bya PVC irashobora guhindurwa muguhitamo ibikoresho bikwiye byo guhagarika hamwe na Polymerisation Catalyst.Ubwoko buto bworoshye burakoreshwa cyane kubijwi byinshi Rigid cyangwa idafite amashanyarazi ya PVC nka PVC Imiyoboro, Windows, Sidings, Imiyoboro.Impamyabumenyi yo guhagarikwa yubunini buke bwa coarser hamwe nuburyo bubi cyane bikurura ibintu byinshi bya Plastisike ikora akuma kuma ku bushyuhe buri munsi ya 80oC.Ubundi bwoko bubi bukoreshwa mugukoresha plastike nka Cable, Inkweto, Soft Calendered Sheeting na Filime nibindi.
Icyiciro cya Emulsion PVC
Emulsion Polymerised PVC nicyo Paste Grade Resin aricyo kandi ibi bikoreshwa cyane kuri Plastisol.Paste grade resin nubunini bwiza cyane PVC ikorwa na spray yumisha Emulsion ya PVC mumazi cyane nkuburyo ifu y amata ikorwa.Shira icyiciro cya resin ikenera imbaraga nyinshi kugirango zitange umusaruro kandi ihenze cyane kuruta guhagarika.Icyiciro cya paste resin itwara imiti ya emulisitiya na catalizator hamwe nayo.Ntabwo rero isukuye kurenza Suspension Polymerized cyangwa Bulk Polymerized PVC.Ibikoresho byamashanyarazi ya paste yo murwego rwa resin plastisol rero birakennye cyane kurenza ihagarikwa rya Resin.Ubusobanuro burakennye kuruta Guhagarikwa cyangwa PVC.Shira icyiciro cya resin iroroshye muburyo, kandi ntabwo ikurura Plastiseri nyinshi mubushyuhe bwicyumba.Ubushyuhe burenze 160-180oC burakenewe kugirango utere plastike muri Resin mugihe cyo gukira.Shira urwego Resin ikoreshwa cyane kuri Cushion Vinyl Igorofa y'ubugari.Ibice bitandukanye bya paste byabugenewe byashizwe hejuru haba kuri substrate ikwiye (Direct Coating) cyangwa kurupapuro rusohora (Transfer coating).Ibice byahujwe ubudahwema mu ziko rirerire hanyuma bikazunguruka nyuma yo gukuramo impapuro.Igorofa nziza yazengurutswe irashobora kugira semitransparent idasanzwe yo kwambara hejuru yimpapuro zanditse kandi zifuro zicaye hejuru yamakoti yuzuye yuzuye kugirango yubake.Ingaruka nyinshi zishimishije kandi zikungahaye zirashoboka kandi izi zerekana impera ndende ya Vinyl Flooring.
Umubare munini wa PVC
Ubwinshi bwa Polymerisation butanga uburyo bwiza bwa PVC resin kuko nta emulisitiya cyangwa ihagarika ikoreshwa.Bakoreshwa cyane cyane mubikorwa bisobanutse.Byakozwe cyane cyane mumatsinda yo hasi ya K agaciro, nkibikoresho bya PVC bidafite amashanyarazi ya Blister Packaging hamwe nandi mafirime ya Calendered / Extruded Transparent firime yatunganijwe neza uhereye kumanota ya K Agaciro.Ibisobanuro muri tekinoroji yo guhagarika byahinduye Bulk PVC mubihe byashize.
Kopi PVC
Vinyl Chloride ikoporora hamwe na comonomers nka Vinyl acetate itanga urutonde rwibintu bifite imiterere yihariye.PVAc cyangwa Copolymer ya Vinyl Chloride na Vinyl acetate nibyingenzi.Gukemura neza mumashanyarazi ya PVAc bituma ihitamo icyambere kuri Icapiro rya Vinyl hamwe na sima ya solvent.Hano hari progaramu idasanzwe ya PVAc muri Floor tiling kandi ni resin yo guhitamo amabati ya Vinyl Asbestos.Ibisigarira mubyukuri nibihuza aho kuba ibyingenzi.Hamwe na Copolymer Resin birashoboka gukora amatafari yo hasi hamwe na Fillers nka Asibesitosi na Kalisiyumu Carbonate bingana na 84% hamwe na Copolymer hamwe nibindi byongeramo ibice biri munsi ya 16%.Urwego rwo hejuru ntirushoboka hamwe na Suspension resin kuko ibishishwa byayo bishonga biri hejuru cyane kandi ntibishobora kwambika no gukwirakwiza urwego rwo hejuru rwuzuza inert.Gariyamoshi idasanzwe yo guhamagara irakenewe kuri Vinyl asibesitosi.Icyakora, Asibesitosi itagikunda, ibicuruzwa nkibi byapfuye buhoro buhoro.
