(A) siv lead ua ntsev stabilizer
Lead ntsev stabilizer yog ib hom additives lug siv nyob rau hauv plastics, coatings, roj hmab thiab lwm yam teb. PVC yog tsuas yog siv nyob rau hauv zus tau tej cov plastics kev lag luam. Nws lub luag haujlwm tseem ceeb yog tswj xyuas PVC los tiv thaiv kev puas tsuaj ntawm oxidizer, inhibit tsim cov kua qaub, yog li stabilizing cov khoom yas. Lub luag haujlwm tseem ceeb ntawm cov hmoov lead ntsev stabilizers hauv cov xim thiab roj hmab kev lag luam yog los tiv thaiv oxidative decomposition thiab thermal aging.
(2) Lub hauv paus ntsiab lus ua haujlwm ntawm txhuas ntsev stabilizer
Lead ntsev stabilizers ua hauj lwm los ntawm kev tsim complexes nrog PVC los yog lwm yam organic tebchaw los tiv thaiv lub degradation ntawm PVC. Cov hmoov txhuas ntsev stabilizer kuj neutralizes cov calcium nyob rau hauv polyvinyl chloride, cia nws tsim cov tebchaw uas tsis yooj yim tawg. Tsis tas li ntawd, cov hmoov lead ntsev stabilizer tseem tuaj yeem tsim cov khoom tsim nyog ntawm cov hlau lead oxide hauv polyvinyl chloride, yog li tiv thaiv oxidation.
(3) Qhov cuam tshuam ntawm txhuas ntsev stabilizer rau ib puag ncig
Lead ntsev stabilizers muaj cov hmoov txhuas, uas tuaj yeem ua rau muaj kev phom sij rau ib puag ncig thiab kev noj qab haus huv yog tias tsis siv lossis ua haujlwm zoo. Cov neeg ua hauj lwm raug cov hmoov lead ntsev stabilizer rau lub sij hawm ntev tuaj yeem ua rau muaj kab mob lead lom. Tsis tas li ntawd, kev siv cov hmoov lead ntsev stabilizers yuav ua rau cov dej khib nyiab thiab cov roj khib nyiab muaj cov hmoov txhuas, ua rau ib puag ncig tsis zoo. Yog li ntawd, thaum siv cov hmoov lead ntsev stabilizers, yuav tsum tau them nyiaj rau kev tiv thaiv ib puag ncig thiab kev noj qab haus huv ntawm tus kheej. Nyob rau tib lub sijhawm, R & D cov neeg ua haujlwm nquag nrhiav lwm txoj hauv kev los txo cov kev cuam tshuam ib puag ncig thiab kev noj qab haus huv.
