PVC plasticizer yog raw khoom hloov tus neeg sawv cev. Ntxiv rau PVC plasticizer rau cov khoom tuaj yeem hloov cov qauv ntawm cov pawg siab, txhim khu cov yas deformation ntawm cov khoom, thiab txhim kho nws qhov yooj yim ntawm cov khoom. Yas, vulcanized roj hmab, nplaum, methylcellulose, epoxy resin, kev kho mob machinery, cable thiab lwm yam khoom. Mastering nws cov kev ua tau zoo yog qhov zoo rau PVC plasticizers kom zoo dua.
Lub luag hauj lwm ntawm PVC yas yog nyob rau hauv tsis muaj zog quab yuam ntawm polymer molecules, yog li txo qhov softening kub, melting kub thiab glaciation kub ntawm lub polymer, ua kom lub liquidity ntawm polymer thaum lub sij hawm ua, thiab kev txhim kho cov txheej txheem ntawm polymer kev ua tau zoo thiab yooj ntawm cov khoom tiav. .
1. Fatty acid ester: Qhov kub thiab txias ua haujlwm ntawm fatty acid ester yog qhov zoo heev, tab sis cov theem kev daws teeb meem ntawm polyvinyl chloride tsuas yog siv los ua cov tshuaj tiv thaiv kab mob khaub thuas-plasticizer thiab phthalate. Feem ntau siv ntau hom yog dyscoprotein thiab cov kua qaub ester.
2. Diabenate: Diebenzya acid yog tam sim no feem ntau siv plasticizer. Muaj ntau ntau yam thiab siab yields. Cov yam ntxwv ntawm kev kub-kub tsis kam. Tam sim no, kev noj cov khoom detonating li ntawm 80-85 feem pua ntawm tag nrho cov khoom siv plasticizers, thiab feem ntau siv yog ob hom: dyscopylbate thiab pub dawb di Xin ester.
3. Phosphoricate: Cia siab tias thiab polyvinyl chloride thiab lwm yam resins muaj cov theem zoo solubility, zoo transparency, tab sis toxicity. Lawv yog ob qho tib si plasticizers thiab nplaim retardants. Qhov ntsuas kub qis ntawm cov tshuaj tsw qab phosphate vinegar tsis zoo, thaum qhov ntsuas kub qis ntawm aliposcopic phosphate zoo dua, tab sis cov thermal stability tsis zoo, thiab cov kav ntev tsis zoo li cov ntxhiab phosphate. Nws lub ntsiab ntau yam yog triglyphylene thiab trigen ester.
4. Epoxy ester: epoxy plasticizers yog cov khoom siv dav siv hauv xyoo tas los no. Nws tuaj yeem tsis tsuas yog nqus cov hydrogen chloride tso tawm los ntawm polyvinyl chloride resin thaum lub sij hawm decomposition tab sis kuj dissolves nrog polyvinyl chloride resin. Yog li tus neeg sawv cev yog tus stabilizer. Nws yog tsuas yog siv los ua tus thawj tswj hwm lub txim rau cov khoom siv polyvinyl chloride nrog huab cua tsis kam. Nws muaj ntau yam xws li epoxy soybean roj, epoxy fatty acid cine ester, thiab lwm yam.
5. Cog plasticizer: Cov plasticizer feem ntau siv tam sim no. Tus nqi ntawm chlorine paraffin yog qis, zoo heev hauv hluav taws xob kev ua tau zoo, thiab nyuaj rau combustible, tab sis cov theem solubility tsis zoo, thiab thermal stability kuj tsis zoo.
6. Alkyl sulfonic acid vinegar: Hom plasticizer no zoo soluble thiab tuaj yeem siv los ua cov yas tseem ceeb. Yog tias lub ntsiab plasticizer siv nrog benzenerite thiab siv, nws yuav zoo dua. Nws cov khoom siv hluav taws xob, kev ua haujlwm hluav taws xob, thiab huab cua tsis kam yog qhov zoo, tab sis kev tiv thaiv txias tsis zoo.
7. Polyol ester: Polyol esters feem ntau yog bipotimodoltanol thiab ethylene glycol. Lub volatility ntawm ob sab tetraazole yog tsawg, zoo los tiv thaiv, nyuaj rau cua sov thiab oxidize, thiab electrocalate. Nws yog ib qho zoo heev tshav kub-resistant thiab yas thiab plasticized Liu. Nws yog tsim rau high-kub hlau rwb thaiv tsev zaub mov txawv, tab sis tus nqi yog kim. Txawm hais tias qhov txias tsis kam ntawm glycol ester yog qhov zoo heev, cov xim yog tsaus dua thiab muaj zog dua.
8. Polyester thiab polarizonate: Polyester plasticizers feem ntau tsis tshua muaj-plasticized, loj viscosity, kev ua haujlwm tsis zoo thiab tsis tshua muaj kub, tab sis tsis tshua muaj volatility, me me tsiv teb tsaws, roj tsis kam thiab xab npum tsis kam rub tawm, yog li nws yog ib qho khoom siv zoo ruaj khov plasticizer. Nws feem ntau yuav tsum tau siv ua ke nrog lub ntsiab plasticizer ntawm lub siab xav.
9. Lwm tus: camphor, crystals nrog tshwj xeeb tsw, siab volatility, me ntsis soluble nyob rau hauv dej, soluble nyob rau hauv feem ntau cov xim solvents. Nws yog ib qho zoo heev plasticizer rau nitrate cellulose thiab fibin.
