Thaum xaiv qhov tsim nyogPVC stabilizer rau tawv tawv, ntau yam muaj feem xyuam rau cov kev cai tshwj xeeb ntawm cov tawv tawv yuav tsum tau xav txog. Nov yog cov ntsiab lus tseem ceeb:
1. Thermal Stability Requirements
Ua Haujlwm Kub:Artificial tawv feem ntau ua tiav ntawm qhov kub thiab txias. PVC stabilizers yuav tsum muaj peev xwm tiv thaiv qhov degradation ntawm PVC ntawm qhov kub thiab txias. Piv txwv li, nyob rau hauv cov txheej txheem calendering, kub tuaj yeem ncav cuag 160 - 180 ° C. Hlau - raws li stabilizers nyiamcalcium - zincthiabbarium - zinc stabilizersyog cov kev xaiv zoo vim tias lawv tuaj yeem ntes cov hydrogen chloride tso tawm thaum lub sijhawm ua PVC, yog li txhim kho thermal stability.
Lub sij hawm kub Resistance:Yog tias cov tawv tawv tawv yog tsim rau cov ntawv thov uas nws yuav raug kub hnyiab rau lub sijhawm ntev, xws li hauv lub tsheb sab hauv, ces cov stabilizers nrog rau qhov zoo tshaj plaws - lub sij hawm tshav kub kub yog xav tau. Organic tin stabilizers paub txog lawv cov thermal stability zoo thiab tsim nyog rau cov xwm txheej zoo li no, txawm hais tias lawv kuj kim heev.
2. Xim Stability Requirements
Kev Tiv Thaiv Yellowing:Qee cov tawv tawv tawv, tshwj xeeb tshaj yog cov xim lub teeb, xav tau kev tswj xyuas nruj ntawm cov xim hloov. Lub stabilizer yuav tsum muaj cov khoom zoo los tiv thaiv yellowing. Piv txwv li,kua barium - zinc stabilizersnrog siab - zoo phosphites tuaj yeem pab tiv thaiv yellowing los ntawm kev tshem tawm cov dawb radicals zoo thiab inhibiting oxidation cov tshuaj tiv thaiv. Tsis tas li ntawd, cov tshuaj antioxidants tuaj yeem muab ntxiv rau hauv lub zog stabilizer los txhim kho xim ruaj khov.
Transparency thiab Xim Purity:Rau pob tshab lossis semi-pob tshab tawv tawv, lub stabilizer yuav tsum tsis txhob cuam tshuam rau cov pob tshab thiab xim purity ntawm cov khoom. Organic tin stabilizers yog nyiam nyob rau hauv cov ntaub ntawv no vim hais tias lawv tsis tsuas yog muab zoo thermal stability tab sis kuj tswj lub pob tshab ntawm PVC matrix.
3. Mechanical Properties Requirements
Flexibility thiab Tensile Strength:Artificial tawv yuav tsum muaj qhov yooj yooj yim thiab lub zog tensile. Stabilizers yuav tsum tsis txhob muaj kev cuam tshuam tsis zoo rau cov khoom no. Qee cov stabilizers, xws li hlau - xab npum - raws li stabilizers, kuj tuaj yeem ua cov roj nplua nyeem, uas pab txhim kho kev ua haujlwm ntawm PVC thiab tswj cov khoom siv ntawm cov khoom kawg.
Hnav Resistance:Nyob rau hauv cov ntaub ntawv uas cov khoom siv tawv tawv yuav raug kev sib txhuam thiab hnav tsis tu ncua, xws li hauv cov rooj tog zaum thiab cov khaub ncaws, lub stabilizer yuav tsum muaj peev xwm ua haujlwm nrog lwm cov khoom siv ntxiv los txhim kho qhov hnav tsis kam ntawm cov khoom. Piv txwv li, los ntawm kev ntxiv qee cov fillers thiab plasticizers nrog rau cov stabilizer, qhov tawv tawv thiab hnav tsis kam ntawm cov tawv tawv tuaj yeem txhim kho.
4. Ib puag ncig thiab kev noj qab haus huv xav tau
Toxicity:Nrog rau kev nce ntxiv ntawm kev tiv thaiv ib puag ncig thiab tib neeg kev noj qab haus huv, cov khoom tsis muaj tshuaj lom stabilizers yog qhov xav tau siab. Rau cov khoom siv tawv tawv siv hauv cov ntawv thov xws li cov khoom siv me nyuam yaus thiab khaub ncaws, hnyav - hlau - tsis muaj stabilizers xws li calcium - zinc thiab tsawg - lub ntiaj teb stabilizers yog qhov tseem ceeb. Cov stabilizers no tau ua raws li cov kev cai ib puag ncig thiab kev noj qab haus huv.
Biodegradability:Qee zaum, muaj kev nyiam rau biodegradable stabilizers kom txo tau qhov cuam tshuam ib puag ncig. Txawm hais tias tam sim no muaj ob peb lub siab biodegradable stabilizers muaj, kev tshawb fawb tseem nyob hauv cheeb tsam no, thiab qee cov stabilizers nrog ib nrab biodegradability tau raug tsim thiab tshuaj xyuas rau kev siv tawv tawv.
5. Kev txiav txim siab nqi
Tus nqi stabilizer:Tus nqi ntawm stabilizers tuaj yeem sib txawv heev. Thaum lub siab-kev ua tau zoo stabilizers zoo li cov organic tin stabilizers muaj cov khoom zoo, lawv kuj kim heev. Hauv qhov sib piv, calcium - zinc stabilizers muab qhov sib npaug zoo ntawm kev ua haujlwm thiab tus nqi thiab tau siv dav hauv kev lag luam tawv tawv. Cov neeg tsim khoom yuav tsum xav txog lawv cov nqi tsim khoom thiab cov nqi lag luam ntawm lawv cov khoom thaum xaiv stabilizers.
Tag Nrho Cov Nqi - Kev Ua Haujlwm:Nws tsis yog tsuas yog tus nqi ntawm lub stabilizer nws tus kheej tseem ceeb, tab sis kuj nws tus nqi tag nrho - kev ua tau zoo. Tus nqi qis dua uas yuav tsum tau siv qis dua kom ua tiav tib theem ntawm kev ua tau zoo raws li tus nqi pheej yig dua yuav raug nqi ntau dua - siv tau ntev. Tsis tas li ntawd, cov yam ntxwv xws li txo cov nqi seem thiab txhim kho cov khoom zoo vim yog kev siv cov stabilizer tshwj xeeb yuav tsum raug coj mus rau hauv tus account thaum ntsuas tus nqi - kev ua tau zoo.
Hauv kev xaus, xaiv txoj cai PVC stabilizer rau cov tawv tawv yuav tsum muaj kev xav txog ntau yam, suav nrog thermal thiab xim stability, txhua yam khoom, ib puag ncig thiab kev noj qab haus huv, nrog rau cov nqi. Los ntawm ua tib zoo tshuaj xyuas cov yam ntxwv no thiab ua cov kev sim thiab kev sim, cov tuam txhab tuaj yeem xaiv qhov tsim nyog stabilizer kom tau raws li cov kev xav tau tshwj xeeb ntawm lawv cov khoom siv tawv tawv.
