Xabagta pvc ee loo isticmaalo sagxadaha
pvc resin loo isticmaalo sagxadaha,
Polyvinyl chloride, Saliida PVC ee sagxadaha iyo sagxadaha,
Sagxadaha PVC waxaa laga soo saaraa maadada polivinyl chloride.Gaar ahaan, waxay ka samaysan tahay polyvinyl chloride iyo resin copolymer sida alaabta ugu weyn, ku daray buuxinta, balaastikada, stabilizers, colorants iyo qalab kale oo caawimo ah, on sheet substrate joogto ah, soo saaray habka daahan ama duuban, extrusion ama habka extrusion, sidaas waa walxo cagaaran oo badbaado leh oo deegaanka u wanaagsan oo aan lahayn formaldehyde.
AALADAHA UGU WEYN EE CAYDIIN EE SABAQA PVC ISTICMAALA WAA ALAAB PVC IYO KAALSIUM KAARBONATE, ALAAB PVC IYO KAALSIUM KAARBONTEEDA WAA IILAALINTA DEEGAANKA KHAYRAADKA LA cusboonaysiin karo, AVIRULENT, LA'AAN SHARCIYEED.Waxaa si weyn loogu isticmaalay nolol maalmeedka dadka, sida tuubooyinka biyaha, alaabta miiska, bacaha faleebada daawada, iwm, waa badeecad cagaaran oo si adag uu u ololeeyo.
Sababtoo ah dabaqa PVC ee caadiga ah kuma jiraan FORMALDEHYDE, Benzene, PHENOL iyo kiimikooyinka kale ee waxyeelada leh, sidoo kale ma laha shucaac.
PVC S-1000 xabagta polyvinyl chloride waxaa soo saaray habsocodka polymerization hakinta iyadoo la isticmaalayo vinyl chloride monomer sida alaabta ceeriin.Waa nooc ka mid ah isku dhafka polymer oo leh cufnaanta qaraabada ah ee 1.35 ~ 1.40.Barta dhalaalkeedu waa qiyaastii 70 ~ 85 ℃.Dejinta kulaylka liidata iyo caabbinta iftiinka, in ka badan 100 ℃ ama waqti dheer qorraxda hoosteeda chloride hydrogen waxay bilaabataa inay burburto, wax soo saarka caaga ah wuxuu u baahan yahay inuu ku daro xasiliyayaal.Alaabta waa in lagu kaydiyaa bakhaar qallalan oo hawo leh.Marka loo eego qaddarka balaastiigga, jilicsanaanta caagga ah waa la hagaajin karaa, iyo xajinta koollada waxaa lagu heli karaa polymerization emulsion.
Fasalka S-1000 waxaa loo isticmaali karaa in lagu soo saaro filim jilicsan, xaashida, maqaarka synthetic, tuubooyinka, bar qaabaysan, hooska, tuubooyinka ilaalinta fiilada, filimka baakadaha, keligood iyo alaabo kale oo jilicsan.
