China Zhongtai resin PVC-ga
China Zhongtai Xabagta PVC,
pvc resin ee tuubada, xabagta PVC ee profile,
Polyvinyl chloride (PVC) waa bilawga peroxides iyo xeryahooda azo ee ku jira vinyl chloride monomer (VCM).Ama hoos ficilka iftiinka iyo kulaylka iyadoo loo eegayo habka polymerization polymerization ee xagjirka bilaashka ah.Vinyl chloride homopolymer iyo vinyl chloride copolymer waxaa lagu magacaabaa vinyl chloride resin.
PVC waxay ahaan jirtay balaastikada ugu wayn aduunka ee ujeedo guud oo si wayn loo isticmaali jiray.Waxaa si weyn loogu isticmaalaa qalabka dhismaha, alaabta warshadaha, waxyaabaha maalinlaha ah, maqaarka sagxadda, lebenka sagxadda, maqaar macmal ah, tuubo, fiilada iyo fiilada, filimka baakadaha, dhalada, alaabta xumbo, shaabadeynta, fiber iyo wixii la mid ah.Isticmaalkeeda ugu muhiimsan waa profile PVC, tuubada PVC, filimka PVC, PVCPVC wax adag iyo saxan, PVC alaabta jilicsan guud ahaan, alaabta baakadaha PVC, darbiga PVC iyo dabaqa, alaabta macaamiisha PVC, alaabta daahan PVC, alaabta xumbo PVC, PVC xaashida hufan, iwm .
PVC oo leh sifooyin farsamo oo aad u fiican, guryaha kiimikada sida caabbinta aashitada iyo daxalka alkali, dabiiciga ah ee ka yimaada is-deminta waxqabadka dab-demiska, heerkulka hooseeya ee wareejinta kuleylka, ilaalinta kulaylka hoos u dhigista dhawaaqa dahaarka, alaabada ilaalinta deegaanka, waxay noqon kartaa astaamo wanaagsan, sida wax ka beddelka jireed iyo kiimikaad waxa uu noqday shay muhiim ah oo ah guriga cagaaran, suuqa dhismaha injineernimada, ilaa kumanaan, sida dad badan iyo dad badani u yaqaaniin oo la aqoonsan yahay.Waqtigan xaadirka ah, kooxda zhongtai oo ah kuwii ugu horreeyay, saddexda ugu sarreeya adduunka ee alaab-qeybiyeyaasha wax-soo-saarka PVC ee gudaha, ayaa sameeyay cabbirka wax-soo-saarka sannadlaha ah ee 2.3 milyan oo tan oo ah polyvinyl chloride (PVC), waxay si xoog leh kor ugu qaadaan adeegsiga alaabada waxqabadka sare ee PVC ee dhammaan Qaybaha nolosha, waa dhinaca horumarka iyo sahayda cagaaran ee dalka si loo hirgeliyo loona fuliyo dib-u-habaynta, sidoo kale waa horumar caafimaad oo mustaqbalka fog leh ee mas'uuliyadda iyo dulqaadka warshadaha.Warqadani waxay inta badan soo bandhigaysaa PVC shan dhinac, sida hordhac, kala-saarid, habka isku-dhafka, wax ka beddelka iyo codsiga.
