PVC resin
Kune 4 mhando dzePVC Resin dzakaunganidzwa ne polymerization nzira
1. Kumiswa Grade PVC
2. Emulsion Grade PVC
3. Bulk Polymerised PVC
4. Copolymer PVC
Kumiswa giredhi PVC
Iyo yakanyanya kupararira mhando, Suspension giredhi PVC inogadzirwa nemapolymerizing madonhwe eVinyl Chloride monomer yakamiswa mumvura.Kana Polymerisation yapera, slurry inoiswa centrifuged uye keke rePVC rinoomeswa zvinyoro nyoro neakakosha masisitimu ekudziya kuitira kuti isaisa iyo isina kugadzikana resin mukupisa kwekupisa.Particle saizi yeresin inotangira pa50-250 microns uye ine porous popcorn senge zvimiro zvinotora nyore Plasticisers.Chimiro chePVC zvidimbu zvinogona kuchinjwa nekusarudza akakodzera ekumisa maajenti uye Polymerisation Catalyst.Mashoma porous marudzi anoshandiswa zvakanyanya kune yakakwira vhoriyamu Rigid kana Unplasticed PVC zvikumbiro sePVC Pipes, Windows, Sidings, Ductings.Suspension grade of a coarser particle size and very porous structures inotora mahombe ePlasticiser achigadzira dryblend patembiricha inodzika kusvika 80oC.Marudzi ane porous anoshandiswa muPlasticised applications seCables, Footwear, Soft Calendered Sheeting and Films etc.
Emulsion Giredhi PVC
Emulsion Polymerised PVC ndiyo iyo Paste Giredhi Resin uye izvi zvinenge zvichishandiswa chete kuPlastisols.Namatidza giredhi resin yakanyatsonaka particle size PVC inogadzirwa nekupfapfaidza kuomesa Emulsion yePVC muMvura zvakanyanya senge magadzirirwo emukaka poda.Paste giredhi resin inoda simba rakawanda kugadzira uye inodhura zvakanyanya kupfuura Suspension resin.Iyo paste giredhi resin inotakura emulsifying makemikari uye catalysts nawo.Naizvozvo haina kuchena kupfuura Suspension Polymerized kana Bulk Polymerized PVC.Iwo Magetsi zvimiro zveNamira giredhi resin plastisols saka ane hurombo zvakanyanya kupfuura Suspension Resin Compounds.Kujeka kune hurombo pane Kumiswa kana Bulk PVC.Paste giredhi resin inobatana muchimiro, uye haitore yakawanda Plasticiser patembiricha yemumba.Tembiricha dzinodarika 160-180oC dzinodiwa kutyaira plasticer muResin panguva yekurapa.Paste giredhi Resin inoshandiswa zvakanyanya kuCushion Vinyl Floorings yehupamhi hwakafara.Akasiyana akaturikidzana emapasta akagadzirwa akakwenenzverwa angave pane akakodzera substrate (Direct Coating) kana paRelease Pepa (Transfer coating).Iwo akaturikidzana anoramba akabatanidzwa muhovhoni refu uye anopetwa mushure mekunge bepa rekuburitsa rabviswa.Iyo yakakungurutswa yakanaka pasi inogona kuve yakaoma semitransparent yekupfeka layer pamusoro peakadhindwa uye ane furo maseru anogara pamusoro pemajasi egasi akazadzwa zvakanyanya kuvaka ukobvu.Mazhinji anoyevedza uye akapfuma mhedzisiro inogoneka uye izvi zvinomiririra iyo yepamusoro yekupedzisira yeVinyl Flooring.
Bulk Polymerised PVC
Bulk Polymerisation inopa iyo yakachena kwazvo fomu yePVC resin sezvo pasina emulsifying kana kumisa maajenti anoshandiswa.Iwo anonyanya kushandiswa mukushandisa pachena.Iwo anonyanya kuitwa kuti awanikwe mune yakaderera K kukosha kwemapoka, seUnplasticed PVC Foils yeBlister Packaging uye mamwe eCalender/Extruded Transparent mafirimu anonyatsogadziriswa kubva kuzasi K Kukosha mamaki.Kunatsiridza muSuspension resin tekinoroji yakabvisa Bulk PVC munguva pfupi yapfuura.
Copolymer PVC
Vinyl Chloride inogadzirwa necomonomers seVinyl acetate inopa huwandu hwema resin ane akasiyana zvivakwa.PVAc kana Copolymer yeVinyl Chloride uye Vinyl acetate ndiyo inonyanya kukosha.Kunyungudika kwakanaka mumasolvents ePVAc kunoita kuti ive sarudzo yepamusoro yeVinyl Printing Inks nemasimende ekunyungudutsa.Iko kune yakasarudzika application yePVAc muFloor tiling uye ndiyo resin yesarudzo yeVinyl Asbestos mataira.Iyo Resin inonyatso bhainda kwete iyo inonyanya kukosha.NeCopolymer Resin zvinokwanisika kugadzira mataira epasi neFillers seAsbestos neCalcium Carbonate accounting inosvika 84% neCopolymer uye zvimwe zvinosanganisa zvinowedzera zvakaderera se16%.Makwiro akadaro haagoneke neSuspension resin sezvo kunyungudika kwayo kunyungudika kwakakwira zvakanyanya uye haigone kupfekedza uye kuvharidzira mazinga akakwira einert filler.Special callendering trains inodiwa kune Vinyl asbestos mataira.Nekudaro neAsbestos inodonha, zvigadzirwa zvakadaro zvakapera zvishoma nezvishoma.
