PVC cob

Cov resin rau zus tau tej cov PVC yas profiles yog polyvinyl chloride resin (PVC), uas yog ib tug polymer polymerized los ntawm vinyl chloride monomers, thiab nws cov zis yog thib ob rau PE, qeb thib ob.

PVC resin tuaj yeem muab faib ua hom xoob (XS) thiab hom compact (Ⅺ) vim qhov sib txawv dispersants hauv polymerization. Qhov loj me me yog {{0}}} {{0}}} 1-0.2 hli, qhov saum npoo yog qhov tsis sib xws thiab ntxeem tau, nws zoo li lub pob paj rwb, yooj yim rau nqus cov yas, cov khoom me me yog tsawg dua. 0.1mm, qhov saum npoo yog li niaj zaus, khoom, thiab nws yog ping pong-puab, tsis yooj yim rau nqus Plasticizers tam sim no siv ntau xoob.

PVC tuaj yeem muab faib ua qib zoo tib yam (PVC tshuaj lom) thiab qib huv '(tsis muaj tshuaj lom PVC). Cov qib huv huv yuav tsum muaj cov ntsiab lus ntawm vinyl chloride (VC) qis dua 10x10-6, uas tuaj yeem siv rau hauv cov khoom noj thiab tshuaj. Cov txheej txheem synthesis sib txawv, PVC tuaj yeem muab faib ua kev ncua PVC thiab emulsion PVC. Raws li lub teb chaws tus qauv GB/T5761-93 "Lub Hom Phiaj Lub Hom Phiaj Polyvinyl Chloride Resin Inspection Standard for Suspension Method", cov txheej txheem raug tshem tawm PVC muab faib ua PVC-SGl rau PVC-SG8Jk resins. Qhov tsawg dua tus lej, qhov ntau dua ntawm polymerization thiab qhov hnyav dua molecular. Loj dua, qhov siab dua lub zog, tab sis qhov nyuaj dua cov yaj ntws, qhov nyuaj dua qhov kev ua haujlwm. Thaum txiav txim siab tshwj xeeb, thaum ua cov khoom muag muag, PVC-SG1, PVC-SG2, thiab PVC-SG3 feem ntau yog siv, thiab yuav tsum tau ntxiv ntau cov yas yas. Piv txwv li, polyvinyl chloride zaj duab xis siv SG-2 resin, thiab 50 mus rau 80 feem ntawm plasticizer ntxiv. Thaum ua cov khoom siv tawv, feem ntau tsis muaj lossis me me yas yas ntxiv, yog li siv PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8. Piv txwv li, SG-4 resin yog siv rau PVC tawv kav, SG{27}} resin yog siv rau yas qhov rooj thiab qhov rais profiles, SG-6 resin yog siv rau cov ntaub ntawv pob tshab, thiab SG{ {29}} thiab SG{30}} resins yog siv rau cov ntaub ntawv tsis zoo. Lub emulsion PVC muab tshuaj yog tsuas yog siv rau cov tawv nqaij, phab ntsa, tawv hauv pem teb thiab cov khoom yas. PVC resins tsim los ntawm qee cov tuam txhab PVC resin raug cais raws li qib ntawm polymerization (the degree ntawm polymerization yog tus naj npawb ntawm cov chains, thiab cov degree ntawm polymerization multiplied los ntawm molecular hnyav ntawm cov saw yog sib npaug rau molecular luj ntawm lub polymer), xws li PVC ua los ntawm Guangzhou Weilianda Plasticizer Co., Ltd. Resin, lub Hoobkas khoom yog SK-700; SK-800; SK-1000; SK-1100; SK-1200, thiab lwm yam. Cov degree sib thooj ntawm polymerization ntawm SG-5 resin yog 1000-1100. Rau lub cev thiab tshuaj lom neeg ntawm PVC resin, saib Tshooj 4.

PVC hmoov yog hmoov dawb nrog qhov ceev ntawm 1.35-1.45g/cm3 thiab pom meej ntom ntawm 0.4-0.5g/cm3. Nyob ntawm cov ntsiab lus plasticizer, nws tuaj yeem yog cov khoom muag muag lossis tawv. Feem ntau, 0-5 qhov chaw ntawm cov yas yas yog cov khoom siv tawv, 5-25 qhov chaw yog cov khoom ib nrab, thiab ntau tshaj 25 qhov chaw yog cov khoom muag muag.

PVC yog ib yam uas tsis yog-crystalline thiab polar polymer nrog siab softening kub thiab melting kub. Feem ntau, PVC ntshiab tuaj yeem ua tau yas thiab ua tiav ntawm 160-210 ~ C. Vim yog lub ncov qaumteb qabteb ntawm macromolecules, PVC tuaj yeem ua plasticized. Qhia txog kev ua haujlwm nyuaj thiab nkig. Ntxiv mus, PVC molecule muaj chlorine pawg. Thaum qhov kub nce mus txog 120 ~ C, ntshiab PVC pib ua rau HCl tshem tawm cov tshuaj tiv thaiv, uas yuav ua rau thermal degradation ntawm PVC. Yog li ntawd, ntau yam additives yuav tsum tau muab ntxiv thaum lub sij hawm ua kom hloov thiab cuam tshuam rau PVC kom nws thiaj li ua tiav rau hauv cov khoom muaj txiaj ntsig.

PVC resin feem ntau yog siv los tsim txhua yam ntawm cov yeeb yaj kiab (xws li niaj hnub luam ntawv zaj duab xis, ntim zaj duab xis, ua liaj ua teb tsev cog khoom zaj duab xis thiab cua sov shrinkable zaj duab xis, thiab lwm yam), txhua yam ntawm cov laug cam, nplooj ntawv (cov nplooj ntawv tuaj yeem siv rau cov khoom siv blister) , txhua yam ntawm cov kav dej (xws li cov kav dej tsis muaj tshuaj lom, cov kav dej siv cov kav dej, cov kav dej pob tshab, thiab lwm yam), ntau yam khoom siv zoo li (xws li lub qhov rooj, qhov rais, cov vaj huam sib luag zoo nkauj), hollow blown fwj (rau cov tshuaj pleev ib ce thiab dej haus), cables, ntau yam kev txhaj tshuaj molded cov khoom thiab cov tawv tawv, Pem teb tawv, slush yas cov khoom ua si, thiab lwm yam.
