Barium-zinc stabilizeryog ib hom stabilizer uas feem ntau siv hauv kev lag luam yas, uas tuaj yeem txhim kho qhov thermal stability thiab UV stability ntawm ntau yam khoom siv yas. Cov stabilizers no paub txog lawv lub peev xwm los tiv thaiv cov khoom siv yas kom tsis txhob lwj, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov thiab qhov chaw kub siab. Hauv tsab xov xwm no, peb yuav tshawb nrhiav kev siv thiab cov txiaj ntsig ntawm barium zinc stabilizers hauv kev lag luam yas.
Cov tshuaj stabilizers barium-zinc feem ntau siv rau hauv kev tsim cov PVC (polyvinyl chloride) thiab lwm yam khoom siv yas. PVC yog ib qho thermoplastic polymer siv dav dav hauv ntau yam kev siv, suav nrog kev tsim kho, kev ntim khoom thiab kev lag luam tsheb. Txawm li cas los xij, nws paub tias PVC yooj yim rau kev puas tsuaj thaum raug cua sov thiab UV hluav taws xob, ua rau muaj kev hloov pauv hauv nws cov khoom siv kho tshuab thiab lub cev. Qhov no yog qhov uas cov tshuaj barium zinc stabilizers tuaj rau hauv.
Lub hom phiaj tseem ceeb ntawm kev siv barium zinc stabilizers hauv PVC thiab lwm yam khoom siv yas yog los tiv thaiv kev puas tsuaj vim muaj cua sov thiab UV. Lub luag haujlwm ntawm cov stabilizers no yog los tshem tawm cov free radicals tsim thaum lub sijhawm puas tsuaj, yog li tiv thaiv cov saw hlau uas ua rau muaj kev tawg ntawm cov saw polymer. Yog li ntawd, cov khoom siv yas tseem ruaj khov thiab khaws lawv cov khoom txawm tias thaum raug rau cov xwm txheej ib puag ncig hnyav.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv barium zinc stabilizers yog lawv qhov kev ruaj khov thermal zoo heev. Qhov no ua rau lawv tsim nyog rau cov ntawv thov uas cov khoom siv yas raug rau qhov kub siab, xws li cov ntaub ntawv tsim kho, cov khoom siv tsheb thiab cov xov hluav taws xob. Tsis tas li ntawd, barium-zinc stabilizers muaj kev tiv thaiv UV zoo heev, ua rau lawv zoo tagnrho rau cov ntawv thov sab nraum zoov uas cov khoom siv yas raug rau tshav ntuj.
Ntxiv rau qhov ruaj khov ntawm thermal thiab UV, barium zinc stabilizers muaj lwm yam txiaj ntsig. Lawv pheej yig thiab ua haujlwm tau zoo, xav tau cov tshuaj tsawg dua piv rau lwm hom stabilizers. Qhov no txhais tau tias cov chaw tsim khoom tsuas yog yuav tsum siv cov stabilizer tsawg kawg nkaus kom ua tiav qib kev ruaj khov xav tau, txuag cov nqi thiab txhim kho kev ua haujlwm tag nrho ntawm cov khoom.
Tsis tas li ntawd xwb, cov tshuaj barium-zinc stabilizers paub txog lawv qhov sib xws nrog ntau yam khoom ntxiv thiab cov xwm txheej ua tiav. Qhov no ua rau lawv muaj ntau yam thiab yooj yim rau kev koom ua ke rau hauv cov txheej txheem tsim khoom, ua rau muaj kev ywj pheej ntau dua hauv kev tsim cov khoom siv yas. Qhov kev hloov pauv thiab kev sib xws no ua rau barium zinc stabilizers yog qhov kev xaiv nrov rau ntau lub tuam txhab tsim khoom yas.
Nws tseem tsim nyog sau tseg tias cov tshuaj barium-zinc stabilizers raug suav hais tias yog ib puag ncig zoo piv rau lwm hom tshuaj stabilizers, xws li cov tshuaj stabilizers uas muaj cov hlau lead. Raws li kev paub txog cov teeb meem ib puag ncig thiab cov cai tswjfwm nce ntxiv, cov tshuaj barium-zinc stabilizers tau dhau los ua qhov kev xaiv ruaj khov thiab zoo rau ib puag ncig rau kev ruaj khov cov khoom siv yas.
Cov tshuaj stabilizers barium-zinc siv dav hauv kev lag luam yas vim lawv muaj peev xwm txhim kho kev ruaj khov ntawm thermal thiab UV, tiv thaiv kev puas tsuaj, thiab tswj cov khoom ntawm cov khoom yas. Nws qhov kev ua tau zoo tshaj plaws, kev siv nyiaj tsim nyog thiab kev phooj ywg ib puag ncig ua rau nws yog qhov kev xaiv nrov rau cov ntawv thov uas qhov kev ruaj khov thiab kev ua haujlwm ntev yog qhov tseem ceeb. Raws li qhov kev thov rau cov khoom yas ua tau zoo txuas ntxiv mus, cov tshuaj barium-zinc stabilizers yuav tsum ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev cai no thaum ua kom tau raws li kev ruaj khov thiab cov qauv kev cai.
