pvc resin esetyenziswa phantsi,
Polyvinyl chloride, PVC resin for siding kunye nomgangatho,
Umgangatho wePVC uveliswa kwizinto zepolyvinyl chloride.Ngokukodwa, yenziwe nge-polyvinyl chloride kunye ne-copolymer resin yayo njengeyona nto iphambili ekrwada, yongeza izihluzi, iiplasticizers, stabilizers, colorants kunye nezinye izinto ezincedisayo, kwiphepha eliqhubekayo le-substrate, eveliswa yinkqubo yokugquma okanye ukuqengqeleka, inkqubo yokukhupha okanye yokukhupha, ngoko ke yinto eluhlaza ekhuselekileyo kunye nokusingqongileyo ngaphandle kwe-formaldehyde.
I-MATERIAL EYINQATHA EQAQWAYO ESETYENZISWAYO KOMgangatho wePVC yi-PVC MATERIAL NE-CALCIUM CARBONATE, PVC MATERIAL NE-CALCIUM CARBONATE ZIZIZIBONELELO ZOKHUSELEKO OKUNGQONGILEYO EZIHLAZIYWAYO, ZIYI-VIRULENT, NGAPHANDLE KWEMIHLA.Isetyenziswe ngokubanzi kubomi bemihla ngemihla yaBantu, njengemibhobho yamanzi, i-tableware, iingxowa ze-infusion zonyango, njl., Imveliso eluhlaza ekhuthazwa ngamandla lilizwe.
Ngenxa yokuba LO Mgangatho oQHELEKILEYO wePVC awuquququki i-FORMALDEHYDE, i-BENZENE, i-PHENOL kunye nezinye iikhemikhali eziyingozi, nazo azinayo i-radioactivity.
I-PVC S-1000 i-polyvinyl chloride resin iveliswa yinkqubo ye-polymerization yokumiswa kusetyenziswa i-vinyl chloride monomer njengento ekrwada.Luhlobo lwekhompawundi yepolymer kunye noxinzelelo olunxulumene ne-1.35 ~ 1.40.Indawo yayo yokunyibilika imalunga ne-70 ~ 85℃.Uzinzo olubi lwe-thermal kunye nokumelana nokukhanya, ngaphezulu kwe-100 ℃ okanye ixesha elide phantsi kwelanga i-hydrogen chloride iqala ukubola, ukuveliswa kweplastiki kufuna ukongeza izizinzi.Imveliso kufuneka igcinwe kwindawo eyomileyo nengenamoya.Ngokomlinganiselo weplastiki, ukuthamba kweplastiki kunokulungiswa, kwaye i-resin yokunamathisela inokufumaneka nge-emulsion polymerization.
IBanga le-S-1000 lingasetyenziselwa ukuvelisa ifilimu ethambileyo, iishiti, isikhumba sokwenziwa, imibhobho, ibha enemilo, umbhobho, imibhobho yokukhusela intambo, ifilimu yokupakisha, i-sole kunye nezinye iimpahla ezithambileyo.
