PVC Stabilizers ntawm yav dhau los, tam sim no, thiab yav tom ntej

Thaum cov tshuaj ntxiv tau pom tias tuaj yeem txo qis cov tshuaj lom neeg thiab lub cev ntawm cov khoom siv thermally-processable tab sis kub-rhiab polymer hu ua poly (vinyl chloride) (PVC), kev lag luam tau yug los. Thiab nrog nws loj hlob lub ntiaj teb no ntawm plastics additives. Stabilizers rau PVC tau los ua thiab kev lag luam nws tus kheej, pub rau hauv thiab tawm ntawm qhov kev lag luam polymer ntau yam, hauv kev sib raug zoo yuav luag. Muaj ntau hom stabilizers siv nyob rau hauv tsib caug xyoo dhau los: inorganics, leads, organics, barium / cadmiums, calcium / zinc, organotins, thiab antimony. Thiab ntau ntau ntxiv tau xeeb tub tab sis tsis ua lag luam: organoleads, organoantimonys, bismuths, indiums, thiab ntau yam ntawm cov tshuaj organic. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov stabilizers? Dab tsi ntawm nag hmo cov khoom tseem nrog peb? Dab tsi yog hom tshiab? Yuav ua li cas yog tag kis cov khoom? Daim ntawv no yuav sim tshuaj xyuas thiab sib tham txog yav dhau los, tam sim no, thiab yav tom ntej ntawm PVC stabilizers; Cov yam tseem ceeb uas yog lub luag haujlwm rau lawv ntau yam, rau kev cuam tshuam rau lawv txoj kev tshawb fawb, kev loj hlob, thiab kev lag luam, thiab yuav ua li cas cov xwm txheej no hloov nrog lub sijhawm.
