1) Absorb thiab neutralize HCL, inhibit nws pib catalytic nyhuv. Hom stabilizer no suav nrog cov ntsev ntsev, organic acid hlau soaps, organotin compounds, epoxy compounds, inorganic ntsev, thiab hlau thiol ntsev. Lawv tuaj yeem cuam tshuam nrog HCL thiab inhibit cov tshuaj tiv thaiv ntawm PVC kom tshem tawm HCL.
2) Hloov cov tshuaj chlorine tsis ruaj khov hauv PVC molecules inhibits HCL tshem tawm. Yog tias cov organic tin stabilizer ua haujlwm nrog cov tshuaj chlorine tsis ruaj khov ntawm PVC molecules, cov organic tin yuav raug hloov nrog cov tshuaj chlorine tsis ruaj khov hauv lub cev sib koom ua ke.
3) Cov tshuaj tiv thaiv ntxiv nrog cov qauv polyene cuam tshuam qhov tsim ntawm cov kab ke loj thiab txo cov xim. Unsaturated acid ntsev los yog esters muaj ob daim ntawv cog lus, uas dhau los ua cov tshuaj tiv thaiv diene ntxiv nrog PVC molecules los ntawm conjugating ob daim ntawv cog lus, yog li cuam tshuam lawv cov qauv conjugated thiab inhibiting xim hloov.
4) Kev ntes cov dawb radicals thiab tiv thaiv oxidation cov tshuaj tiv thaiv, qhov thermal stabilizer tuaj yeem muaj ib lossis ntau yam teebmeem.
Qhov zoo tshaj plaws PVC thermal stabilizer yuav tsum yog cov khoom siv ntau yam lossis cov khoom sib xyaw ua ke uas tuaj yeem ua tiav cov haujlwm hauv qab no: ua ntej, hloov cov khoom siv thiab tsis ruaj khov; Qhov thib ob yog kom nqus thiab nruab nrab HCL tso tawm thaum lub sij hawm ua PVC, tshem tawm cov nyhuv catalytic degradation ntawm HCL; Qhov thib peb yog ua kom tsis muaj zog lossis passivate hlau ions thiab lwm yam kev puas tsuaj impurities uas ua lub luag haujlwm catalytic hauv degradation; Thib plaub, ntau hom tshuaj tiv thaiv tuaj yeem thaiv qhov kev loj hlob txuas ntxiv ntawm cov nyiaj tsis txaus ntseeg thiab inhibit degradation xim; Thib tsib, nws muaj kev tiv thaiv thiab kev tiv thaiv ntawm lub teeb ultraviolet. Feem ntau, cov cua sov stabilizers yog siv ua ke raws li lawv cov kev ua tau zoo, thiab lawv cov kev siv tus kheej yog tsawg. Ntxiv mus, feem ntau ntau yam yog nyob rau hauv hmoov daim ntawv, nrog rau ib co yog heev toxic chemicals. Txhawm rau kom yooj yim rau kev siv, tiv thaiv plua plav lom, txo cov tshuaj lom lossis hloov nrog cov khoom tsis muaj tshuaj lom, ntau hom kev sib xyaw ua ke tau tsim muaj ob qho tib si hauv tebchaws thiab thoob ntiaj teb hauv xyoo tas los no. Piv txwv li, German Bear brand composite stabilizer series, as well as organic tin or composite organic tin stabilizers los ntawm cov teb chaws xws li Tebchaws Meskas, Lub Tebchaws Yelemees, Nyiv, thiab Netherlands, txhua tus muaj kev lag luam loj hauv Suav teb. Yog li ntawd, nws yog ib qho tseem ceeb rau kev tsim kho ntawm Tuam Tshoj txoj kev lag luam yas kom txhawb nqa kev siv cov khoom siv hluav taws xob tshiab uas muaj txiaj ntsig zoo, tus nqi qis, tsis muaj plua plav, tsis muaj tshuaj lom lossis tsis muaj tshuaj lom.
