Thaum xaiv ib qho chaw uas haumPVC stabilizer rau tawv nqaij cuav, ntau yam tseem ceeb uas cuam tshuam nrog cov kev xav tau tshwj xeeb ntawm cov tawv cuav yuav tsum tau xav txog. Nov yog cov ntsiab lus tseem ceeb:
1. Cov Kev Cai Ruaj Khoov Thermal
Kub Ua Haujlwm:Cov tawv cuav feem ntau raug ua tiav ntawm qhov kub siab. Cov tshuaj stabilizer PVC yuav tsum muaj peev xwm tiv thaiv kev puas tsuaj ntawm PVC ntawm cov kub no. Piv txwv li, hauv cov txheej txheem calendering, qhov kub tuaj yeem ncav cuag 160 - 180 ° C. Cov tshuaj stabilizer ua los ntawm hlau zoo licalcium-zincthiabbarium - zinc stabilizersyog cov kev xaiv zoo vim tias lawv tuaj yeem ntes tau cov hydrogen chloride uas tso tawm thaum lub sijhawm ua PVC, yog li ua kom muaj kev ruaj khov thermal.
Kev Tiv Thaiv Kub Ntev:Yog tias cov tawv cuav yog siv rau cov ntawv thov uas nws yuav raug rau qhov kub thiab txias ntev, xws li hauv tsheb, ces xav tau cov stabilizers uas tiv taus cua sov tau ntev. Cov organic tin stabilizers paub txog lawv qhov kev ruaj khov thermal zoo heev thiab tsim nyog rau cov xwm txheej zoo li no, txawm hais tias lawv kim heev.
2. Cov Kev Cai Ruaj Ntseg Xim
Kev Tiv Thaiv Kab Mob Daj:Qee cov tawv nqaij cuav, tshwj xeeb tshaj yog cov uas muaj xim sib dua, yuav tsum tau tswj hwm kev hloov xim kom zoo. Lub stabilizer yuav tsum muaj cov khoom tiv thaiv kev daj zoo. Piv txwv li,cov kua barium - zinc stabilizersNrog cov phosphites zoo tuaj yeem pab tiv thaiv kev daj los ntawm kev tshem tawm cov dawb radicals thiab tiv thaiv cov tshuaj tiv thaiv oxidation. Tsis tas li ntawd, cov tshuaj antioxidants tuaj yeem ntxiv rau hauv lub stabilizer system kom txhim kho xim ruaj khov.
Pob tshab thiab Xim Huv Si:Rau cov tawv nqaij cuav uas pob tshab lossis ib nrab pob tshab, cov tshuaj stabilizer yuav tsum tsis txhob cuam tshuam rau qhov pob tshab thiab xim huv ntawm cov khoom siv. Cov tshuaj stabilizer organic tin yog qhov nyiam dua hauv qhov no vim tias lawv tsis tsuas yog muab kev ruaj khov zoo heev tab sis kuj tseem tswj tau qhov pob tshab ntawm PVC matrix.
3. Cov Kev Cai ntawm Cov Khoom Siv Kho Tshuab
Kev ywj pheej thiab lub zog tensile:Cov tawv cuav yuav tsum muaj qhov yooj ywm thiab lub zog tensile zoo. Cov khoom ruaj khov yuav tsum tsis txhob muaj qhov cuam tshuam tsis zoo rau cov khoom no. Qee cov khoom ruaj khov, xws li cov hlau - xab npum - cov khoom ruaj khov, kuj tuaj yeem ua haujlwm ua cov roj nplua nyeem, uas pab txhim kho kev ua haujlwm ntawm PVC thiab tswj cov khoom siv kho tshuab ntawm cov khoom kawg.
Kev Hnav Tsis kam:Hauv cov ntawv thov uas tawv cuav raug kev sib txhuam thiab hnav ntau zaus, xws li hauv rooj tog thiab khaub ncaws, lub stabilizer yuav tsum muaj peev xwm ua haujlwm ua ke nrog lwm cov khoom ntxiv kom txhim kho qhov hnav tsis kam ntawm cov khoom. Piv txwv li, los ntawm kev ntxiv qee cov khoom sau thiab cov yas ua ke nrog lub stabilizer, qhov tawv ntawm qhov chaw thiab kev hnav tsis kam ntawm cov tawv cuav tuaj yeem txhim kho.
4. Cov Kev Cai Ib puag ncig thiab Kev Noj Qab Haus Huv
Kev lom:Vim muaj kev tsom mus rau kev tiv thaiv ib puag ncig thiab kev noj qab haus huv ntawm tib neeg, cov tshuaj stabilizer uas tsis muaj tshuaj lom neeg thiaj li muaj neeg xav tau ntau. Rau cov tawv nqaij cuav uas siv rau hauv cov ntawv thov xws li cov khoom siv rau menyuam yaus thiab khaub ncaws, cov tshuaj stabilizer uas tsis muaj hlau hnyav xws li calcium - zinc thiab cov tshuaj stabilizer uas tsis tshua muaj av yog qhov tseem ceeb. Cov tshuaj stabilizer no ua raws li cov cai ib puag ncig thiab kev noj qab haus huv.
Kev puas tsuaj ntawm cov tsiaj txhu:Muaj tej lub sij hawm, muaj kev nyiam siv cov khoom ruaj khov uas lwj tau los ntawm kev lwj kom txo tau qhov cuam tshuam rau ib puag ncig. Txawm hais tias tam sim no muaj ob peb lub khoom ruaj khov uas lwj tau tag nrho, kev tshawb fawb tseem tab tom ua hauv thaj chaw no, thiab qee cov khoom ruaj khov uas lwj tau ib nrab tab tom raug tsim thiab soj ntsuam rau kev siv hauv tawv cuav.
5. Kev Xav Txog Tus Nqi
Tus nqi ntawm Stabilizer:Tus nqi ntawm cov stabilizers tuaj yeem sib txawv ntau heev. Txawm hais tias cov stabilizers ua tau zoo xws li cov organic tin stabilizers muaj cov yam ntxwv zoo heev, lawv kim heev. Qhov sib piv, calcium - zinc stabilizers muab qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi thiab siv dav hauv kev lag luam tawv cuav. Cov chaw tsim khoom yuav tsum xav txog lawv cov nqi tsim khoom thiab tus nqi ua lag luam ntawm lawv cov khoom thaum xaiv cov stabilizers.
Tag Nrho Cov Nqi - Kev Ua Tau Zoo:Tsis yog tsuas yog tus nqi ntawm lub stabilizer nws tus kheej xwb uas tseem ceeb, tab sis kuj yog nws qhov kev siv nyiaj tag nrho. Lub stabilizer kim dua uas xav tau cov tshuaj tsawg dua kom ua tiav tib theem ntawm kev ua tau zoo li ib qho pheej yig dua yuav ua tau zoo dua rau lub sijhawm ntev. Tsis tas li ntawd, cov yam xws li txo cov nqi pov tseg thiab cov khoom zoo dua vim kev siv lub stabilizer tshwj xeeb yuav tsum tau coj los xav thaum soj ntsuam qhov kev siv nyiaj.
Xaus lus, kev xaiv cov khoom siv PVC stabilizer zoo rau cov tawv cuav yuav tsum tau xav txog ntau yam, suav nrog kev ruaj khov ntawm thermal thiab xim, cov khoom siv kho tshuab, cov kev xav tau ib puag ncig thiab kev noj qab haus huv, nrog rau tus nqi. Los ntawm kev soj ntsuam cov ntsiab lus no thiab ua kev sim thiab kev xeem, cov chaw tsim khoom tuaj yeem xaiv cov khoom siv stabilizer zoo tshaj plaws kom tau raws li qhov xav tau tshwj xeeb ntawm lawv cov khoom tawv cuav.
