Cov resin los ua PVC yas profiles yog polyvinyl chloride resin (PVC).Polyvinyl chloride yog ib qho polymer ua los ntawm vinyl chloride monomer.
PVC resin tuaj yeem faib ua ob hom, hom xoob (XS) thiab hom compact (XJ), nyob ntawm tus neeg sawv cev dispersing hauv polymerization.Qhov loj me me yog 0.1-0.2 hli, qhov saum npoo yog qhov tsis sib xws, ntxeem tau, zoo li paj rwb, yooj yim rau nqus cov yas, cov khoom me me yog tsawg dua 0.1 hli, nto yog li niaj zaus, khoom, rooj ntaus pob tesniv, nyuaj rau nqus cov yas, ntawm tam sim no, ntau hom xoob yog siv.
PVC tuaj yeem muab faib ua qib zoo tib yam (PVC tshuaj lom) thiab qib huv (tsis muaj tshuaj lom PVC).Qib Hygienic yuav tsum muaj vinyl chloride (VC) cov ntsiab lus tsawg dua 10 × 10-6, uas tuaj yeem siv rau hauv cov khoom noj thiab tshuaj.Cov txheej txheem sib txawv, PVC tuaj yeem muab faib ua kev ncua PVC thiab emulsion PVC.Raws li lub teb chaws tus qauv GB / T5761-93 "Kev soj ntsuam tus qauv rau lub hom phiaj dav dav polyvinyl chloride resin rau txoj kev raug ncua", cov txheej txheem ncua kev kawm ntawv PVC tau muab faib ua PVC-SG1 rau PVC-SG8 yim hom resins, uas yog tus lej tsawg dua, Qhov ntau dua ntawm cov txheej txheem ntawm polymerization, qhov hnyav molecular kuj Qhov loj dua lub zog, siab dua cov yaj ntws, thiab ua haujlwm nyuaj dua.
Thaum xaiv cov khoom muag muag, PVC-SG1, PVC-SG2, thiab PVC-SG3 feem ntau yog siv, thiab ntau cov yas yuav tsum tau ntxiv.Piv txwv li, polyvinyl chloride zaj duab xis yog ua los ntawm SG-2 resin, thiab 50 mus rau 80 feem ntawm cov yas yog ntxiv.Thaum ua cov khoom siv tawv, cov yas yas feem ntau tsis ntxiv lossis ntxiv me me, yog li siv PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, thiab PVC-SG8.
Piv txwv li, SG-4 resin yog siv rau PVC tawv yeeb nkab, SG-5 resin yog siv rau yas qhov rooj thiab qhov rais profile, SG-6 resin yog siv rau cov pob tshab zaj duab xis, thiab SG-7 thiab SG-8 resin yog siv rau. nyuaj foamed profile.Txoj kev emulsion PVC muab tshuaj yog tsuas yog siv rau cov tawv tawv, phab ntsa, tawv hauv pem teb thiab cov khoom yas.Qee cov PVC resin manufacturers nkoj PVC cob raws li qib ntawm polymerization (degree ntawm polymerization yog tus naj npawb ntawm chav tsev txuas, cov degree ntawm polymerization multiplied los ntawm molecular hnyav ntawm cov saw yog sib npaug rau molecular hnyav ntawm lub polymer), xws li PVC. resin ua los ntawm Shandong Qilu Petrochemical Plant, lub Hoobkas khoom Nws yog S-700;S-800;S-1000;S-1100;S-1200 Nws.
SG-5 cob muaj degree ntawm polymerization ntawm 1,000 txog 1,100.Cov hmoov PVC yog cov hmoov dawb uas muaj qhov ntom ntom ntawm 1.35 thiab 1.45 g / cm3 thiab pom meej ntom ntom ntawm 0.4 txog 0.5 g / cm3.Peb suav hais tias cov ntsiab lus ntawm plasticizers hauv PVC cov khoom yog cov khoom muag muag thiab tawv.Feem ntau, cov ntsiab lus plasticizer yog 0 ~ 5 qhov chaw rau cov khoom tawv, 5 ~ 25 qhov chaw rau cov khoom siv tawv, thiab ntau tshaj 25 qhov chaw rau cov khoom muag muag.
Zibo Junhai Tshuaj yog cov khoom lag luam sab saum toj ntawm Pvc Resin.Peb tuaj yeem muab PVC Resin S3, PVC Resin SG5, PVC Resin SG8, PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.Thiab nws yog los ntawm cov tuam txhab saum toj kawg nkaus ntawm Tuam Tshoj, xws li Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong Tai PVC Resin, Tianye PVC Resin.ext.
Polyvinyl chloride muaj cov yam ntxwv zoo ntawm cov khoom siv raw (roj, limestone, coke, ntsev thiab cov nkev), cov txheej txheem tsim khoom, tus nqi qis, thiab ntau yam kev siv.Nws tau dhau los ua qhov thib ob loj tshaj plaws-lub hom phiaj cob hauv ntiaj teb tom qab polyethylene cob.29% ntawm lub ntiaj teb tag nrho cov khoom siv hluavtaws siv.Polyvinyl chloride yog ib qho yooj yim rau txheej txheem thiab tuaj yeem ua tiav los ntawm molding, laminating, txhaj tshuaj molding, extrusion, calendering, tshuab moulding, thiab lwm yam. raws li cov khoom yas tawv xws li daim hlau, qhov rooj thiab qhov rais, cov kav dej thiab cov li qub.
