Hauv kev tsim tawv cuav,Cov khoom siv PVC kub stabilizersua lub luag haujlwm tseem ceeb. Ua kom zoo rau qhov tshwm sim ntawm cov xwm txheej thermal decomposition, thaum tswj hwm qhov nrawm ntawm cov tshuaj tiv thaiv kom ntseeg tau tias qhov ruaj khov ntawm cov qauv polymer molecular, yog li ua kom ntseeg tau tias kev vam meej ntawm tag nrho cov txheej txheem ntau lawm.
(1)Barium cadmium zinc thermal stabilizer
Thaum ntxov calendering txheej txheem, barium cadmium zinc heat stabilizers feem ntau siv. Barium ntsev tuaj yeem ua kom cov khoom ruaj khov thaum lub sijhawm ua haujlwm kub ntev, cadmium ntsev ua lub luag haujlwm ruaj khov hauv nruab nrab ntawm kev ua tiav, thiab zinc ntsev tuaj yeem ntes cov hydrogen chloride tsim los ntawm PVC degradation thaum pib.
Txawm li cas los xij, vim yog qhov tshuaj lom ntawm cadmium, kev siv cov stabilizers no tau raug ntau qhov kev txwv vim tias cov kev cai ib puag ncig tau dhau los ua qhov nruj dua.
Barium zinc stabilizers, ua ib hom tseem ceeb ntawm cov cua sov stabilizer, yog siv dav hauv kev tsim cov tawv hluavtaws. Hauv cov txheej txheem txheej, barium zinc stabilizer ua tau zoo. Hauv cov txheej txheem plasticization ntawm qhov cub, nws tuaj yeem tiv thaiv cov txheej kom tsis txhob tig daj thiab tawg vim qhov kub siab, ua rau cov tawv tawv tiav lawm ci thiab ruaj khov xim.
(3)Calcium Zinc composite heat stabilizer
Niaj hnub nim no, cov tshuaj calcium zinc composite heat stabilizers tau dhau los ua cov khoom siv tseem ceeb. Hauv cov txheej txheem calendering, nws tuaj yeem tswj tau qhov ruaj khov ntawm cov ntaub ntawv uas raug rau qhov kub siab sib tov thiab dov. Cov ntsev calcium yog lub luag haujlwm ntawm kev ruaj khov thermal mus sij hawm ntev, thaum cov ntsev zinc raug kho raws sijhawm ntawm kev puas tsuaj thermal thawj zaug. Cov khoom ntxiv organic ntxiv txhim kho qhov ruaj khov, ua rau cov tawv nqaij sib npaug thiab ua tau zoo.
Ntxiv mus, vim nws cov yam ntxwv zoo rau ib puag ncig thiab tsis muaj tshuaj lom, nws yog qhov tshwj xeeb tshaj yog rau cov teb uas muaj cov kev xav tau ib puag ncig siab xws li cov khoom ua si rau menyuam yaus thiab tawv cuav rau cov khoom noj khoom haus.
TopJoy Tshuajtsom mus rau kev tshawb fawb thiab kev tsim cov PVC stabilizers, thiab nws cov khoom tau cog qoob loo tob hauv daim teb ntawm cov tawv hluavtaws tau ntau xyoo. Nrog kev ruaj khov zoo heev, kev sib raug zoo, thiab kev tiv thaiv huab cua zoo heev, qhov zoo ntawm cov tawv hluavtaws tau lees paub zoo, thiab nws ua tau zoo hauv ob qho tib si xim ruaj khov thiab cov khoom siv lub cev, yog li tau txais kev ntseeg siab ntawm cov neeg siv khoom hauv tsev thiab txawv teb chaws.
