Plasticizer, los yog tus neeg sawv cev ntawm tus neeg yas cev (Taiwanese Suav, yog lub plhaub taum loj Suav). Puas yog kev lag luam yog siv rau hauv cov khoom hauv polymer ntxiv, hauv kev ua yas ua ntxiv rau cov khoom siv no, tuaj yeem ua kom yooj yim, yooj yim txheej txheem, siv tau rau industrial cov hom phiaj.
Plasticizer yog hom polymer additive, nws ntau yam yog ib qho tsis muaj kob, kua txob, dav siv hauv kev lag luam. Feem ntau siv cov khoom yas, roj hmab, tshuaj nplaum, cellulose, resins, cov khoom kho mob, cables thiab lwm cov khoom phav phav. Lub ntsiab ntau yam ntawm epoxy plasticizers: epoxidized soybean roj, Yasizer epoxidized acetyl linseed roj methyl ester, epoxy furfuryl oleate ester thiab thiaj li nyob rau. Hauv PVC cov khoom, cov yam ntxwv ntawm cov cuab yeej thiab kev ruaj ntseg siv dav. Epoxy plasticizer yog ib hom kev zoo yas rau yas, Plasticizer uas yog ua los ntawm cov tshuaj tiv thaiv oxidation ntawm cov kua roj hauv cov organic peroxide, cov tshuaj lom neeg muaj tsawg heev, Plasticizer yog qhov zoo tshaj plaws yog tsis yog cov tshuaj lom neeg, cov hluav taws xob-resistant thiab lub teeb ruaj ruaj.
Plasticizer plays lub luag haujlwm tseem ceeb hauv cov khoom zoo yas. Nws muaj ntau txoj kev los hloov kho thiab hloov, qhov kev loj hlob ntawm kev siv cov cuab yeej tshiab yog nce, ntau qhov tshiab ntau dua, ntau dua qhov kev paub tias muaj ntau tshaj, kev ntsuam xyuas txoj kev tsim nyog dua, thiab cov yas yas yog kev txhim kho hauv lub voj voog ntawm "development-application-toxicology test-risk assessment-redevelopment". Yog li, qhov tseeb ntawm kev siv cov yas yas yog qhov kev lag luam yuav muaj kev noj qab haus huv ntawm tus yuam sij. Ua li no, cov tsev lag luam yas ntiav yuav tsum ua hauj lwm cov kev hloov kho. Txawv teb chaws tuaj sab nraud nce raws li non-toxic lossis environmentally friendly thiab biodegradable plasticizers.
Plasticizer yog cov khoom siv loj tshaj plaws nyob rau hauv kom muaj nuj nqis, cov zis tawm thiab cov khoom noj khoom haus. Thaum xyoo 2012, lub ntiaj teb no thoob ntiaj teb tag nrho ntawm kwv yees li 7.5 lab ton / xyoo, lub ntiaj teb tag nrho tus nqi ntawm cov khoom yos hav zoov 5,9 lab tons / xyoo, thaum lub caij cov teb chaws Asmeskas tau lees paub txog 22%, Plasticizer thaj av Asia-Pacific yog 38%, teb chaws Europe rau 25%, lwm thaj chaw tau lees paub txog 15%. PVC yog cov tib neeg siv cov yas yas, Plasticizer accounting rau 95% ntawm tag nrho cov nqi ntawm cov yas yas hauv ntiaj teb, thiab me ntsis li 90% nyob hauv North America. Tus nqi ntawm cov yas siv yas siv Polyolefin, styrene, Engineering Plastics, polyethylene acetal thiab cellulose heev me me. Hauv kev ua lag luam plawg, phthalic acid ester occupies txoj hauj lwm ntawm 69%, cov nram qab no yog cov rog rog rau 8%, epoxy category accounted rau 7%, benzene tri-acid esters accounted rau 4%, lwm tus accounted rau 2% .
Txij li thaum plasticizers ze rau cov ntse muag ntawm PVC muag malls heev, lawv tau qeeb kom muaj kev loj hlob zoo, thiab yuav tsum nce siab npaum li cas txhua xyoo ntawm 2.5%, nce 6.1 lab tons hauv 2009.
Tus qauv ntawm cov yas rau yas kom loj hlob, nruam, Kev tswj hwm kev tswj hwm lub computer, cov txheej txheem qhuav ntau tau tam sim no mus txog 100,000 ton / xyoo. Muaj ntau hom kev lag luam nrog lub peev xwm los hloov rau kev ua lag luam tuaj yeem muaj zog, ntau ntawm cov yam ntxwv ntawm ntau cov khoom sib txawv ntawm cov khoom ua rau tshwj xeeb kev ua haujlwm ntawm hom plasticizer xav tau. Vim tias qhov zoo ntawm DOP, qhov tseem ceeb thiab kev noj mov tseem muaj nyob rau ntawm txoj hauj lwm ntawm phthalate esters, ob zaug, DINP (phthalic acid diisocyanate), DIDP (phthalic acid phthalate), thiab lwm yam estylose esters tseem tsim muaj kev lag luam, los ua ib qho tseem ceeb ntawm hom phthalic acid esters. Ntxiv rau phthalic acid ester plasticizers, txias heev-resistant zoo heev fatty acid esters, tsis muaj tshuaj lom neeg thiab ruaj khov epoxy ester, Yasizer kub kub resistant benzene tri-acid ester, tsis txav polyester, nplaim zoo hluav taws xob retardant phosphate ester hauv lub tsev ntawm cov yas yas rau ib qho sib koom ua ke, zoo ib yam tsim nyog ntawm qhov kev tsim cov yas rau khoom yas.
