Plasticizers yog cov chav kawm loj tshaj plaws ntawm cov yas additives nyob rau hauv cov nqe lus ntawm kom muaj nuj nqis, tso zis thiab noj. Tam sim no, tag nrho lub ntiaj teb no plasticizer muaj peev xwm yog kwv yees li 7.5 lab tons / xyoo, thiab lub ntiaj teb no plasticizer ntau lawm yog 5.9 lab tons / xyoo, uas North America suav rau 22 feem pua, Asia-Pacific suav rau 38 feem pua, Tebchaws Europe suav txog 25. feem pua, thiab lwm cheeb tsam suav txog 15 feem pua. PVC yog cov neeg siv ntau tshaj plaws ntawm plasticizers, suav txog 95 feem pua ntawm tag nrho lub ntiaj teb plasticizer noj thiab me ntsis ntau dua 90 feem pua hauv North America. Polyolefins, styrene, engineering plastics, polyvinyl butyral thiab cellulose yog siv nyob rau hauv tsawg heev. Hauv kev lag luam plasticizer, phthalates suav txog 69 feem pua, ua raws li aliphatic 8 feem pua, epoxy 7 feem pua, trimellitate 4 feem pua, thiab lwm yam 2 feem pua.
Vim tias cov yas yas muaj feem cuam tshuam nrog kev lag luam muag muag muag muag PVC, txoj kev loj hlob qeeb, tab sis tswj kev loj hlob tsis tu ncua, uas xav tias yuav loj hlob ntawm qhov nruab nrab txhua xyoo ntawm 2.5 feem pua, ncav cuag 6.1 lab tons hauv 2009.
Tam sim no, cov qauv tsim ntawm plasticizers tab tom txhim kho mus rau qhov loj, tsis tu ncua thiab kev tswj hwm lub computer, thiab cov peev txheej ntawm ib txheej tau mus txog ntau dua 100,000 tons / xyoo. Multi-ntau yam serial ntau lawm muaj cov yam ntxwv ntawm muaj zog adaptability rau lub lag luam thiab loj ntau lawm yooj kom tau raws li cov kev xav tau ntawm txawv yas ua khoom rau tshwj xeeb functional plasticizer ntau yam. Vim tias qhov kev ua tau zoo ntawm cov nqi ntawm DOP, cov zis thiab kev noj haus tseem tseem muaj cov phthalate esters, ua raws li DINP (diisononyl phthalate), DIDP (diisodecyl phthalate), thiab ncaj qha kev txhim kho cov saw cawv esters kuj ceev, thiab nws yuav tsum tau. ua ib qho tseem ceeb ntau yam ntawm phthalates. Ntxiv nrog rau phthalate plasticizers, fatty acid esters nrog kev ua haujlwm txias txias, epoxy esters nrog kev ruaj ntseg tsis muaj tshuaj lom, kub-resistant trimellitic esters, non-migrating polyesters, nplaim retardant Phosphate esters nrog cov khoom zoo tag nrho rau ib qho kev faib ua feem hauv plasticizer qauv, tsim lub plasticizer ntau lawm system nrog cov qauv tsim nyog. )
Thaum tshav kub kub stabilizers. Thaum tshav kub kub stabilizer yog ib qho tseem ceeb ntawm cov khoom siv yas. Kev yug thiab kev loj hlob ntawm cov cua sov stabilizer thiab PVC resin yog synchronized. Lawv tsuas yog siv rau hauv kev ua ntawm PVC cob. Yog li ntawd, qhov piv ntawm cov cua sov stabilizer rau PVC cob thiab cov khoom muag muag thiab tawv hauv PVC yog kev sib raug zoo. Tam sim no, thoob ntiaj teb kev noj txhua xyoo yog kwv yees li 500, 000 tons, thiab ntau yam tseem ceeb yog cov ntsev ntsev, organotin, hlau soaps, composite stabilizers thiab organic additives. Cov qauv siv ntawm cov cua sov stabilizer sib txawv ntawm lub teb chaws mus rau lub teb chaws. Hauv Tebchaws Meskas, cov khoom sib xyaw ua ke suav txog 40 feem pua -50 feem pua ntawm tag nrho cov khoom noj, thiab organotin suav txog ze li 40 feem pua. Ntawm cov cua sov stabilizers, cadmium-dawb, tsis muaj txhuas, hmoov av-dawb thiab tsis muaj txhuas hloov tau dhau los ua qhov tseem ceeb ntawm kev lag luam txoj kev loj hlob. Cov kev cai nruj ntawm kev tiv thaiv ib puag ncig yog tsav kev hloov pauv ntawm cov cua sov stabilizers. Txhawm rau tiv thaiv kev nyob ib puag ncig ntawm tib neeg, ntau lub tebchaws tau dhau txoj cai txwv tsis pub siv cov hlau hnyav hnyav hauv PVC ua. European PVC heat stabilizer manufacturers tau cog lus tias tus nqi ntawm cov hlau lead-muaj cov khoom siv hluav taws xob yuav raug txiav ib nrab los ntawm 2010, thiab tsis muaj cov hmoov txhuas yuav ua tiav los ntawm 2015. Ntau lub tebchaws hauv Tebchaws Europe tau siv organotin-based lossis calcium-zinc-raws li lwm txoj hauv kev. xwb. European txhuas stabilizer noj yuav raug txo los ntawm 120, 000 tons / xyoo hauv 1999 mus rau 80,000 tons / xyoo hauv 2010. Qhov kev thov rau cov khoom siv hluav taws xob ua kom sov nyob hauv thaj av Asia-Pacific kuj yog cia siab tias yuav txo qis heev. Cov stabilizers tshiab, suav nrog organotin-based systems (OBS), tau dhau los muaj nyob hauv Tebchaws Meskas.
