PVC yas formulation
PVC yas formulation,
PVC cob, PVC cob thiab additive, PVC cob rau kev tsim cov yeeb nkab, PVC SG-5, PVC SG-8, TSI SG-7,
PVC yas formulation yog tsim los ntawmPVC cob thiab additives, uas yog additives raws li qhov muaj nuj nqi yog muab faib ua: tshav kub stabilizer, lubricant, processing modifier, cuam tshuam modifier, muab tub lim, laus tus neeg saib xyuas, colorant thiab hais txog.Ua ntej tsim PVC formulation, peb yuav tsum xub nkag siab txog cov khoom ntawm PVC cob thiab ntau yam additives.
Raw khoom thiab additives
PVC cob
PVC yas profile zus tau tej cov resin yog polyvinyl chloride resin (PVC), PVC yog ua los ntawm vinyl chloride monomer polymerization polymer, tso zis thib ob rau PE, qeb thib ob.
PVC resin tuaj yeem muab faib ua hom xoob (XS) thiab nruj hom (ⅺ) vim qhov sib txawv dispersants hauv polymerization.Loose particle loj yog 0.1-0.2mm, qhov saum npoo yog tsis sib xws, ntxeem tau, paj rwb pob, yooj yim rau nqus cov yas, compact particle loj yog qis dua 0.1 hli, cov kev cai saum npoo, khoom, rooj ntaus pob tesniv, tsis yooj yim rau nqus plasticizer, siv tam sim no ntawm xoob hom ntau dua.
PVC tuaj yeem muab faib ua qib zoo tib yam (PVC tshuaj lom) thiab qib kev noj qab haus huv '(tsis muaj tshuaj lom PVC).Cov qib kev noj qab haus huv ntawm vinyl chloride (VC) cov ntsiab lus qis dua LOXL0-6, tuaj yeem siv rau hauv cov zaub mov thiab tshuaj.Cov txheej txheem hluavtaws sib txawv, PVC tuaj yeem muab faib ua kev ncua PVC thiab emulsion PVC.Raws li lub teb chaws tus qauv GB / T5761-93 "txhim kho txoj kev dav polyvinyl chloride resin soj ntsuam qauv", txoj kev ncua kev kawm ntawv PVC yog muab faib ua PVC-SGL rau PVC-SG8JK resin, tus me me, qhov ntau dua ntawm polymerization, ntau dua. qhov hnyav molecular, lub zog siab dua, tab sis qhov nyuaj ntawm cov yaj ntws, kev ua haujlwm kuj nyuaj dua.Kev xaiv tshwj xeeb, ua cov khoom muag muag, kev siv dav dav ntawm PVC-SGL, PVC-SG2, PVC-SG3 hom, yuav tsum tau ntxiv ntau cov yas yas.Piv txwv li, PVC zaj duab xis siv SG-2 resin, ntxiv 50 mus rau 80 qhov chaw ntawm plasticizer.Thiab thaum ua cov khoom lag luam nyuaj, tsis txhob ntxiv lossis ntxiv cov yas yas hauv ib qho me me feem ntau, siv PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 yog li.Xws li PVC tawv yeeb nkab siv SG-4 resin, yas qhov rooj thiab qhov rais profiles siv SG-5 resin, tawv pob tshab ntawv siv SG-6 resin, tawv ua npuas ncauj profiles siv SG-7, SG-8 resin.Thiab emulsion PVC muab tshuaj yog tsuas yog siv rau cov tawv tawv, phab ntsa thiab hauv pem teb tawv thiab dip yas khoom.Qee cov PVC resin manufacturers ntawm PVC resin raws li polymerization degree (polymerization degree yog tus naj npawb ntawm chav tsev saw, polymerization degree multiplied los ntawm molecular hnyav ntawm cov saw yog sib npaug zos rau molecular hnyav ntawm lub polymer) kev faib, xws li Shandong Qilu petrochemical nroj tsuag. ntau lawm ntawm PVC cob, Hoobkas khoom rau SK-700;SK - 800 hli;SK - 1000;SK - 1100 hli;SK - 1200, thiab lwm yam. Cov degree sib thooj ntawm polymerization ntawm SG-5 cob yog 1000 - 1100. Lub cev thiab tshuaj lom neeg ntawm PVC resin pom plaub.
PVC hmoov yog hmoov dawb nrog qhov ceev ntawm 1.35 - 1.45 g / cm3 thiab pom meej ntom ntawm 0.4-0.5 g / cm3.Tshawb xyuas cov ntsiab lus ntawm cov yas yas tuaj yeem yog mos, cov khoom tawv, cov ntsiab lus ntawm cov yas yas 0-5 yog cov khoom tawv, 5-25 yog cov khoom siv tawv, ntau tshaj 25 yog cov khoom muag muag.
PVC yog ib hom amorphous, polar polymer, softening kub thiab melting kub yog siab, ntshiab PVC feem ntau yuav tsum nyob rau hauv 160-210 ~ C plasticizing ua, vim lub ncov qaumteb qabte daim ntawv cog lus ntawm macromolecules thiaj li hais tias PVC qhia ib tug nyuaj thiab nkig kev kawm.Ntxiv mus, PVC molecules uas muaj cov tshuaj chlorine, thaum kub txog 120 ~ C, PVC ntshiab yuav pib tshem tawm HCl cov tshuaj tiv thaiv, yuav ua rau thermal degradation ntawm PVC.Yog li ntawd, txhua yam ntawm cov khoom siv ntxiv yuav tsum tau ntxiv rau hauv kev ua ntawm PVC kev hloov kho thiab kev hloov pauv, kom nws tuaj yeem ua tiav rau hauv cov khoom siv tau zoo.
PVC resin feem ntau yog siv rau kev tsim ntau yam ntawm nyias zaj duab xis (xws li niaj hnub luam ntawv zaj duab xis, ntim zaj duab xis, ua liaj ua teb tsev cog khoom zaj duab xis, tshav kub shrinkable zaj duab xis, thiab lwm yam), txhua yam ntawm phaj, ntawv, ntawv yuav siv tau rau Cov khoom siv hlwv), txhua yam ntawm cov kav dej, xws li tsis muaj tshuaj lom ntawm cov yeeb nkab threading yeeb nkab, pob tshab hose, thiab lwm yam), txhua yam ntawm cov khoom siv tshwj xeeb, xws li lub qhov rooj, qhov rais, cov phaj decorating, hollow tshuab lub raj mis (rau cov tshuaj pleev ib ce thiab dej haus), Cable, txhua yam kev txhaj tshuaj thiab cov khoom siv tawv tawv, tawv hauv pem teb, cov khoom ua si yas, thiab lwm yam.
Zibo Junhai Tshuaj yog thawj tus neeg sawv cev ntawm Sinopec Qilu, lub ntsiab PVC hom raws li hauv qab no.
