Thaum xaiv cov antioxidants thiab lub teeb stabilizers, hom tshuaj antioxidants thiab lub teeb stabilizers yuav tsum tau txiav txim siab raws li hom, qauv, cov khoom siv thiab txheej txheem txheej txheem ntawm cov khoom yas, ntau yam thiab ntau npaum li cas ntawm lwm yam tshuaj additives, siv ib puag ncig thiab lub neej ntawm cov khoom, thiab lwm yam. Kev xaiv cov khoom lag luam antioxidants thiab lub teeb stabilizers yuav tsum tau xa mus rau cov hauv paus ntsiab lus hauv qab no.
Ib qho yog mobility.
Cov khoom siv yas, tshwj xeeb tshaj yog cov khoom lag luam opaque nrog thaj tsam me me rau qhov ntim qhov sib piv (lossis qhov hnyav piv), cov tshuaj tiv thaiv oxidation feem ntau tshwm sim rau ntawm qhov chaw ntawm cov khoom, uas yuav tsum muaj cov tshuaj antioxidants thiab lub teeb stabilizers kom tsis tu ncua hloov mus rau sab hauv ntawm cov khoom yas mus rau qhov saum npoo ntawm cov khoom, yog li ua lub luag haujlwm. Txawm li cas los xij, yog tias qhov kev tsiv teb tsaws chaw ceev ntawm qhov chaw ntawm cov khoom yog ceev heev thiab qhov kev tsiv teb tsaws yog loj heev, cov tshuaj tiv thaiv antioxidant thiab lub teeb stabilizer yuav volatilize rau hauv ib puag ncig ntawm cov khoom, los yog diffuse mus rau lwm yam xov xwm nyob rau hauv kev sib cuag nrog cov khoom. nto ntawm cov khoom thiab ua rau poob. Nws yog xyaum tsis zam thiab yuav tsum tau txiav txim siab thaum tsim cov formulation.
Qhov thib ob yog compatibility.
Cov polymers ntawm cov yas polymers feem ntau tsis yog-polar, thaum cov polymers ntawm antioxidants thiab lub teeb stabilizers muaj ntau theem ntawm polarity thiab tsis zoo compatibility. Feem ntau, antioxidants thiab photostabilizers yog ua ke nrog polymer yaj ntawm qhov kub thiab txias, thiab cov molecules ntawm antioxidants thiab photostabilizers yog haum ntawm polymer molecules thaum lub polymer yog solidified. Nyob rau hauv ntau npaum li cas ntawm cov formulation, tshwj xeeb yuav tsum tau them nyiaj mloog mus rau lub melting ntawm antioxidants thiab lub teeb stabilizers nyob rau hauv lub kub ua.
Qhov thib peb yog processability.
Thaum lub sij hawm ua cov khoom yas, ntxiv antioxidants thiab lub teeb stabilizers yuav hloov lub yaj viscosity thiab ntsia hlau torque ntawm cov resin. Yog hais tias lub melting point ntawm cov antioxidant thiab lub teeb stabilizer txawv heev los ntawm cov melting ntau ntawm cov resin, qhov tshwm sim ntawm anti-oxidant, lub teeb stabilizer bias los yog ntsia hlau tuav yuav tshwm sim. Thaum lub melting point ntawm cov antioxidant thiab lub teeb stabilizer yog qis dua qhov kub ntawm 100 degree los yog ntau tshaj, cov antioxidant thiab lub teeb stabilizer yuav tsum tau ua rau ib tug tej yam concentration ntawm masterbatch, thiab ces tov nrog cov resin.
Qhov thib plaub yog stability.
Antioxidants thiab lub teeb stabilizers yuav tsum nyob ruaj khov nyob rau hauv cov ntaub ntawv yas, muaj me ntsis volatilization poob nyob rau hauv kev siv ib puag ncig thiab high-temperature ua, tsis txhob hloov xim los yog tsim xim, tsis txhob decompose (tshwj tsis yog rau antioxidants nrog thermal stability), thiab tsis txhob sib tov nrog lwm yam additives Cov tshuaj tsis zoo tshwm sim tshwm sim, tsis txhob corrode mechanical khoom, thiab tsis yooj yim muab rho los ntawm lwm yam tshuaj nyob rau hauv cov khoom nto. Anti-amine teeb stabilizers feem ntau yog cov tshuaj alkaline tsawg. Thaum cov tshuaj tiv thaiv amines raug xaiv los ua lub teeb stabilizers nyob rau hauv cov ntaub ntawv yas, cov tshuaj yuav tsum tsis txhob muaj lwm yam acidic additives, thiab cov khoom siv yas yuav tsum tsis txhob siv nyob rau hauv acidic ib puag ncig.
Hauv kev tsim tshuaj lom neeg thiab kev ua haujlwm, qhov tseem ceeb ntawm kev xaiv kom raug ntawm cov tshuaj tua kab mob antioxidants thiab lub teeb stabilizers yog qhov tseeb ntawm nws tus kheej, tab sis ntxiv rau hom thiab qauv, cov khoom zoo kuj tseem ceeb heev. Thaum koj yuav cov khoom tsis zoo, nws yuav muaj txiaj ntsig zoo rau cov nyhuv. Yog li ntawd, thaum yuav cov tshuaj antioxidants thiab lub teeb stabilizers, koj yuav tsum xaiv cov platforms tsis tu ncua thiab cov tuam txhab ncaj ncees
