Cov kua barium zinc stabilizertsis muaj cov hlau hnyav, siv dav hauv kev ua cov khoom mos thiab semi-rigid PVC. Nws tsis tsuas yog txhim kho qhov ruaj khov ntawm PVC, tiv thaiv kev puas tsuaj thermal thaum lub sijhawm ua, tab sis kuj pab tswj qhov pob tshab thiab xim ntawm cov khoom PVC, tshwj xeeb tshaj yog haum rau kev tsim cov yeeb yaj kiab pob tshab thiab xim.
Hauv kev tsim cov yeeb yaj kiab PVC, kev siv cov kua barium zinc stabilizer tuaj yeem daws cov teeb meem xws li cov yeeb yaj kiab tsis zoo, cov duab ntxoov ntxoo lossis cov kab txaij, thiab cov pos huab. Los ntawm kev ua kom zoo dua cov khoom sib xyaw ua ke, qhov ruaj khov thermal ntawm cov yeeb yaj kiab PVC tuaj yeem txhim kho tau zoo thaum tswj nws cov pob tshab thiab xim.
Cov txiaj ntsig ntawm cov kua Ba Zn stabilizer:
(1) Kev ruaj khov zoo ntawm thermal:Cov kua Ba-Zn stabilizerstuaj yeem ua kom muaj kev ruaj khov dynamic thiab static thermal thaum lub sijhawm ua tiav, tiv thaiv PVC degradation ntawm qhov kub siab.
(2) Txhim Kho Kev Pom Tseeb: Cov kua Ba Zn stabilizers tuaj yeem ua rau lub teeb transmittance ntawm PVC cov khoom thiab txhim kho kev pom tseeb, uas yog qhov tseem ceeb rau PVC zaj duab xis uas xav tau kev pom tseeb siab.
(3) Kev ua tau zoo heev: Cov kua stabilizers yooj yim rau disperse hauv PVC, uas pab txhim kho kev ua haujlwm ntau lawm thiab cov khoom zoo.
(4) Xim pib zoo thiab xim ruaj khov: Cov kua Ba Zn stabilizers tuaj yeem muab xim pib zoo thiab txo cov xim hloov pauv thaum lub sijhawm ua tiav.
(5) Cov yam ntxwv zas xim uas tiv taus sulfur: Cov kua Ba Zn stabilizers muaj cov yam ntxwv zas xim uas tiv taus sulfur zoo heev, uas pab tswj cov tsos thiab kev ua tau zoo ntawm PVC zaj duab xis.
(6) Cov yam ntxwv ib puag ncig: Cov kua Ba Zn stabilizer tsis muaj cov hlau hnyav xws li cadmium thiab lead, ua tau raws li cov kev cai tam sim no rau kev tiv thaiv ib puag ncig thiab kev noj qab haus huv. Tebchaws Europe tau txwv tsis pub siv cov stabilizers uas muaj cadmium, thiab hauv North America, lwm cov hlau sib xyaw stabilizers maj mam siv los hloov lawv. Qhov kev thov rau cov stabilizers PVC uas zoo rau ib puag ncig hauv kev lag luam thoob ntiaj teb tab tom loj hlob, uas yog tsav tsheb siv Ba Zn stabilizers.
(7) Kev tiv thaiv huab cua zoo heev: Cov kua Ba Zn stabilizer tuaj yeem txhim kho kev tiv thaiv huab cua ntawm PVC zaj duab xis, tiv taus kev puas tsuaj los ntawm cov teeb meem ultraviolet, thiab ua rau nws muaj lub neej ntev dua hauv kev siv sab nraum zoov.
(8) Kev ua haujlwm tiv thaiv nag lossis daus: Cov kua Ba Zn stabilizer tsis precipitate thaum lub sijhawm ua haujlwm, uas pab tswj kev sib npaug thiab kev ruaj khov ntawm PVC zaj duab xis.
(9) Haum rau cov qauv sau siab: Cov kua Ba Zn stabilizers yog qhov tsim nyog tshwj xeeb rau cov qauv sau siab, uas pab txo cov nqi thiab txhim kho kev ua haujlwm ntawm cov khoom siv.
Zuag qhia tag nrho, cov kua Ba Zn stabilizer ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb yaj kiab PVC vim nws qhov ua tau zoo, kev phooj ywg ib puag ncig, thiab ntau yam kev ua haujlwm.
