Methyl Tin Stabilizer

Kev Piav Qhia Luv:

Methyl Tin Stabilizer yog ib qho ntawm cov khoom siv tiv thaiv cua sov. Cov yam ntxwv tseem ceeb yog kev ua haujlwm siab, pob tshab siab, tiv taus cua sov zoo heev, thiab tiv taus kev ua qias tuaj ntawm vulcanization. Feem ntau siv rau hauv cov yeeb yaj kiab ntim khoom noj thiab lwm yam khoom PVC pob tshab. Nws muaj kev tiv thaiv zoo heev ntawm kev ua ntej xim ntawm cov khoom PVC thaum lub sijhawm ua tiav, tiv taus UV zoo heev thiab ruaj khov mus sij hawm ntev, zoo fluidity, zoo khaws xim thaum lub sijhawm ua tiav, thiab zoo pob tshab khoom. Tshwj xeeb, nws qhov kev ruaj khov photothermal tau mus txog qib thoob ntiaj teb, thiab nws tuaj yeem tswj tau kev siv dua ntawm kev ua tiav theem ob. Organotin stabilizer yog siv dav hauv kev lag luam polyvinyl chloride (PVC) resin ua lag luam, tsim nyog rau PVC calendering, extrusion, tshuab molding, txhaj tshuaj molding thiab lwm yam txheej txheem ua molding, tshwj xeeb tshaj yog haum rau tshuaj, khoom noj, dej haus kav dej thiab lwm yam txheej txheem ua tiav PVC. (Lub stabilizer no yuav tsum tsis txhob siv nrog cov hlau lead, cadmium thiab lwm yam stabilizers.) Cov ntsiab lus poob qis

cov lus piav qhia txog cov khoom

Cov tshuaj tiv thaiv cua sov (PVC) thiab lwm yam polymers uas muaj chlorine. Methyl tin stabilizer yog ib qho amorphous high polymer. Vim yog cov qauv tshwj xeeb ntawm PVC, nws yuav tsis zam tsis tau ntawm qhov kub ua tiav, ua rau xim tsaus dua, txo cov khoom siv lub cev thiab cov khoom siv kho tshuab, thiab txawm tias poob tus nqi siv. Cov tshuaj tiv thaiv cua sov tau tsim thiab tsim los daws qhov teeb meem no. Raws li cov qauv tshuaj sib txawv, cov tshuaj tiv thaiv cua sov feem ntau yog muab faib ua cov ntsev txhuas, xab npum hlau, organic tin, av tsis tshua muaj, organic antimony thiab cov tshuaj tiv thaiv organic. Cov khoom sib txawv muaj lawv tus kheej cov yam ntxwv kev ua tau zoo thiab haum rau ntau qhov chaw sib txawv. Nyob rau hauv xyoo tas los no, kev lag luam PVC tau tsim kho sai, uas tau ua rau kev txhim kho sai ntawm kev lag luam tiv thaiv cua sov. Ntawm ib sab tes, txoj kev xav ntawm cov tshuaj tiv thaiv cua sov tau dhau los ua qhov zoo meej ntau dua, uas muab cov xwm txheej rau kev tau txais cov khoom lag luam PVC zoo tagnrho; ntawm qhov tod tes, cov khoom tshiab haum rau ntau qhov chaw sib txawv tau tsim kho tas li, tshwj xeeb tshaj yog vim muaj kev lom ntawm cov ntsev txhuas thiab cov hlau hnyav. Qhov laj thawj yog tias cov tuam txhab ua PVC ua ntej xaiv cov tshuaj tiv thaiv cua sov tsis muaj tshuaj lom.

Hauv kev tsim cov lag luam ua PVC, ntxiv rau qhov xav tau cov khoom siv cua sov kom ua tau raws li qhov ruaj khov thermal, lawv feem ntau yuav tsum muaj kev ua haujlwm zoo, tiv taus huab cua, xim pib, kev ruaj khov lub teeb, thiab cov kev cai nruj rau lawv cov ntxhiab tsw thiab viscosity. Tib lub sijhawm, muaj ntau yam khoom PVC, suav nrog cov ntawv, cov kav dej, cov ntaub ntawv, cov pwm tshuab, cov pwm txhaj tshuaj, cov khoom ua npuas ncauj, cov tshuaj nplaum, thiab lwm yam. Feem ntau ntawm cov qauv ua tiav ntawm cov lag luam tsim cov khoom PVC yuav tsum tau tsim los ntawm cov lag luam lawv tus kheej. Yog li ntawd, kev xaiv cov khoom siv cua sov thaum lub sijhawm ua PVC yog qhov tseem ceeb heev. Organotin cov khoom siv cua sov yog cov khoom siv cua sov uas tau tshawb pom txog tam sim no.
