Nyob rau hauv Artificial Leather Production,Thaum tshav kub kub PVC stabilizersua lub luag haujlwm tseem ceeb.Txhim kho qhov tshwm sim ntawm thermal decomposition phenomenon, thaum raug tswj cov tshuaj tiv thaiv tus nqi kom muaj kev ruaj ntseg ntawm polymer molecular qauv, yog li ua kom cov kev vam meej ntawm tag nrho cov txheej txheem ntau lawm.
(1)Barium cadmium zinc thermal stabilizer
Nyob rau hauv cov txheej txheem calendering thaum ntxov, barium cadmium zinc kub stabilizers feem ntau siv. Barium ntsev tuaj yeem ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv thaum lub sijhawm ua haujlwm kub ntev, cadmium ntsev ua lub luag haujlwm ruaj khov nyob rau hauv nruab nrab ntawm kev ua, thiab zinc ntsev tuaj yeem ntes cov hydrogen chloride uas tsim los ntawm PVC degradation thaum pib.
Txawm li cas los xij, vim muaj cov tshuaj toxicity ntawm cadmium, kev siv cov stabilizers no tau raug ntau yam kev txwv vim tias ib puag ncig yuav tsum tau ua nruj me ntsis.
Barium zinc stabilizers, raws li ib qho tseem ceeb ntawm cov cua sov stabilizer, yog dav siv nyob rau hauv zus tau tej cov hluavtaws tawv.In txheej txheej, barium zinc stabilizer ua tau zoo. Nyob rau hauv lub qhov cub plasticization txheej txheem, nws muaj peev xwm tiv thaiv lub txheej los ntawm tig daj thiab nkig vim qhov kub thiab txias, ua tiav cov khoom siv tawv tawv uas ci thiab ruaj khov hauv cov xim.
(3)Calcium Zinc Composite Thaum tshav kub kub stabilizer
Niaj hnub no, calcium zinc composite heat stabilizers tau dhau los ua qhov tseem ceeb. Nyob rau hauv cov txheej txheem calendering, nws muaj peev xwm tswj tau qhov ruaj khov ntawm cov ntaub ntawv raug rau high-temperature mixing thiab dov. Calcium ntsev dais lub luag hauj lwm ntawm lub sij hawm ntev thermal stability, thaum zinc ntsev tau kho raws sij hawm ntawm thawj thermal decomposition. Organic additives ntxiv txhim kho cov nyhuv stability, ua rau cov tuab tuab thiab kev ua tau zoo ntawm cov tawv tawv.
Ntxiv mus, vim nws cov yam ntxwv zoo ib puag ncig thiab tsis muaj tshuaj lom, nws yog qhov tshwj xeeb tshaj yog tsim rau thaj chaw uas muaj ib puag ncig zoo xws li cov menyuam yaus cov khoom ua si thiab cov tawv tawv rau cov khoom ntim khoom noj.
TopJoy Chemical tsom mus rau kev tshawb fawb thiab tsim cov PVC stabilizers, thiab nws cov khoom tau cog qoob loo rau hauv cov tawv hluavtaws tau ntau xyoo. Nrog zoo thermal stability, zoo compatibility, thiab zoo heev huab cua tsis kam, zoo ntawm hluavtaws tawv yog zoo guaranteed, thiab nws ua tau zoo nyob rau hauv ob qho tib si xim durability thiab lub cev zog, yog li tau txais kev ntseeg siab ntawm domestic thiab txawv teb chaws cov neeg muas zaub.
