Cov khoom tsim thiab kev faib tawm

• Ua tus qauv

Polyvinyl chloride yog cov khoom siv polymer uas siv ib qho chlorine atom los hloov ib qho hydrogen atom hauv polyethylene, thiab yog ib qho amorphous polymer nrog me me ntawm crystalline qauv. Cov qauv ntawm cov khoom no yog raws li nram no: -(CH2-CHCl)n-. PVC yog linear polymer uas VCM monomers feem ntau txuas nrog lub taub hau-tail qauv. Cov pa roj carbon atoms tau teeb tsa hauv tus qauv zigzag, thiab tag nrho cov atoms txuas nrog σ bonds. Tag nrho cov pa roj carbon atom yog sp3 hybridized.

Muaj luv luv syndiotactic stereoregular qauv ntawm PVC molecular saw. Raws li qhov kub ntawm polymerization txo, qhov syndiotactic tacticity nce. Hauv cov qauv macromolecular ntawm PVC, muaj cov qauv tsis ruaj khov xws li lub taub hau-rau-lub taub hau qauv, ceg saw, ob daim ntawv cog lus, allyl chloride, tertiary chlorine, thiab lwm yam, uas ua rau thermal deformation thiab kev laus tsis zoo. Tom qab ua txuj ua kev sib txuas, cov kev tsis zoo no tuaj yeem raug tshem tawm.

Tactical qauv ntawm PVC

Crosslinking muab faib ua hluav taws xob crosslinking thiab tshuaj lom neeg crosslinking.

1. Radiation crosslinking. High-zog rays yog siv, feem ntau cov rays generated los ntawm cobalt 60 hluav taws xob qhov chaw los yog cov hluav taws xob rays generated los ntawm electron acceleration, thiab tom kawg yog tsuas yog siv. Tom qab ntawd ntxiv tus pab cuam crosslinking (monomer nrog ob lossis ntau dua carbon-carbon ob daim ntawv cog lus) rau kev sib txuas. Txawm li cas los xij, nws nyuaj rau kev khiav lag luam thiab xav tau cov cuab yeej siv siab.

2. Tshuaj lom neeg sib txuas. Triazole dimercaptoamine ntsev (FSH) yog siv rau kev sib txuas. Txoj kev sib txuas sib txuas yog tias amine thiab sulfhydryl sib xyaw ua ke los tua cov pa roj carbon-chlorine polar bonds los ua cov tshuaj tiv thaiv kev hloov pauv. Tom qab kev sib txuas sib txuas, UV tsis kam, hnyav ua haujlwm, kub tsis kam, cuam tshuam toughening thiab lwm yam khoom ntawm cov khoom yuav zoo dua.

Main Classification

Raws li qhov sib txawv ntawm daim ntawv thov, PVC tuaj yeem muab faib ua: dav PVC cob, qib siab ntawm polymerization PVC resin, cross-linked PVC cob. General-purpose PVC cob yog tsim los ntawm polymerization ntawm vinyl chloride monomer nyob rau hauv qhov kev txiav txim ntawm ib tug pib; high degree ntawm polymerization PVC resin yog hais txog cov resin uas yog polymerized los ntawm kev ntxiv cov saw extender rau cov yas chloride monomer polymerization system; cross-linked PVC resin yog ib qho resin tau los ntawm kev ntxiv tus neeg sawv cev crosslinking uas muaj diene thiab polyene rau cov yas chloride monomer polymerization system.

Raws li txoj kev tau txais vinyl chloride monomer, nws tuaj yeem muab faib ua calcium carbide method, ethylene method thiab imported (EDC, VCM) monomer method (ethylene method and the imported monomer method is commonly referred to as the ethylene method).

Raws li cov txheej txheem polymerization, PVC tuaj yeem muab faib ua plaub pawg: txoj kev tshem tawm PVC, emulsion method PVC, bulk method PVC, tov method PVC. Suspension-processed polyvinyl chloride yog ib qho kev tso zis ntau tshaj plaws, suav txog li 80 feem pua ​​​​ntawm tag nrho cov zis ntawm PVC. Suspension PVC muab faib ua rau tus qauv raws li qhov tseeb viscosity: XS-1, XS-2...XS-6; XJ-1, XJ-2..., XJ-6. Lub ntsiab lus ntawm txhua tsab ntawv hauv tus qauv: X-txheej txheem txheej txheem; S-loj hom; J-tight type.

Raws li cov ntsiab lus ntawm plasticizer, PVC yas feem ntau muab faib ua: tsis yog-plasticized PVC, cov ntsiab lus plasticizer yog 0; nruj PVC, cov ntsiab lus yas yog tsawg dua 10 feem pua; semi-rigid PVC, plasticizer cov ntsiab lus Rau mos PVC, cov ntsiab lus yas yog 30-70 feem pua ​​; rau PVC paste yas, cov ntsiab lus plasticizer yog ntau tshaj 80 feem pua.
