Taw qhia:
Hauv kev tsim thiab ua cov PVC yeeb nkab fittings, kev xaiv ntawm additives plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg.Ob feem ntau siv additives rau PVC ua yog organic tin formulations thiab calcium-zinc formulations.Hauv tsab xov xwm no, peb yuav sib piv qhov zoo thiab qhov tsis zoo ntawm ob qho kev tsim tawm hauv cov ntsiab lus ntawm kev tsim cov PVC granules rau hauv qab PVC yeeb nkab fittings.
Organic Tin Formulation:
Organic tin formulation yog hais txog kev siv cov organic tin-raws li cov khoom sib xyaw ua kom sov thiab cov roj nplua nyeem hauv kev tsim cov PVC.Cov qauv no tau siv dav hauv kev ua PVC vim nws cov khoom zoo heev thaum tshav kub kub thiab lubricating zog.
Qee qhov zoo ntawm cov organic tin formulation hauv kev tsim cov PVC yeeb nkab fittings suav nrog:
1.Enhanced tshav kub stability: Organic tin compounds ua raws li cov cua sov stabilizers, tiv thaiv thermal degradation ntawm PVC thaum ua.Qhov no ua rau kev txhim kho kev ua tau zoo thiab txo qhov kev pheej hmoo ntawm degradation-txog qhov tsis xws luag hauv cov khoom kawg.
2.Superior lubrication: Organic tin tebchaw kuj pom zoo heev lubricating zog, uas pab txhawb cov ndlwg ntawm PVC yaj thaum ua.Qhov no ua rau kom zoo dua pwm filling thiab txhim kho nto tiav ntawm PVC yeeb nkab fittings.
Ntawm qhov tod tes, muaj qee qhov tsis zoo cuam tshuam nrog kev siv cov organic tin formulation, suav nrog:
1.Kev txhawj xeeb txog ib puag ncig: Qee cov organic tin tebchaw, xws li organotins, paub tias muaj tshuaj lom thiab ua rau ib puag ncig.Lawv txoj kev siv tau raug tswj lossis txwv tsis pub nyob hauv qee thaj tsam vim muaj kev pheej hmoo ntawm ib puag ncig thiab kev noj qab haus huv.
2.Cov nqi: Organic tin tebchaw tuaj yeem kim dua piv rau lwm cov qauv stabilizer, ua rau tag nrho cov nqi tsim khoom ntawm PVC yeeb nkab fittings.
Calcium-Zinc Formulation PVC Compound:
Calcium-zinc formulation, raws li lub npe qhia, suav nrog kev siv cov calcium thiab zinc ntsev ua kom sov stabilizers hauv PVC ua.Cov qauv no muaj lwm txoj hauv kev rau cov organic tin tebchaw thiab tau txais kev nyiam nyob rau xyoo tas los no.Qhov zoo ntawm calcium-zinc formulation nyob rau hauv zus tau tej cov PVC yeeb fittings muaj xws li:
1.Kev txhim kho ib puag ncig profile: Calcium-zinc tebchaw feem ntau suav tias yog ib puag ncig zoo dua piv rau cov organic tin compounds.Lawv muaj qis duaxicity thiab ua rau muaj kev pheej hmoo tsawg dua rau tib neeg kev noj qab haus huv thiab ib puag ncig.
2.Cov txiaj ntsig zoo: Calcium-zinc formulations feem ntau yuav raug nqi ntau dua li cov organic tin formulations.Qhov no tuaj yeem pab txo cov nqi tsim khoom ntawm PVC yeeb nkab fittings thiab ua rau lawv muaj kev sib tw ntau dua hauv kev ua lag luam.
Txawm li cas los xij, calcium-zinc formulation kuj muaj ob peb drawbacks:
1.Heat stability txwv: Calcium-zinc stabilizers yuav tsis muaj tib theem ntawm kev ruaj ntseg thaum tshav kub kub li cov organic tin tebchaw.Yog li ntawd, tej zaum yuav muaj kev pheej hmoo siab ntawm thermal degradation thaum lub sij hawm processing, uas tuaj yeem cuam tshuam qhov zoo ntawm PVC yeeb nkab fittings.
2.Txoj kev sib tw: Lub lubricating zog ntawm calcium-zinc stabilizers yuav tsis zoo li cov organic tin tebchaw.Qhov no tuaj yeem ua rau muaj kev sib tw hauv pwm filling thiab muaj peev xwm cuam tshuam rau qhov chaw tiav thiab qhov tseeb qhov tseeb ntawm cov khoom kawg.
Taw qhia:
Hauv kev tsim thiab ua cov PVC yeeb nkab fittings, kev xaiv ntawm additives plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg.Ob feem ntau siv additives rau PVC ua yog organic tin formulations thiab calcium-zinc formulations.Hauv tsab xov xwm no, peb yuav sib piv qhov zoo thiab qhov tsis zoo ntawm ob qho kev tsim tawm hauv cov ntsiab lus ntawm kev tsim cov PVC granules rau hauv qab PVC yeeb nkab fittings.
Xaus:
Thaum xaiv cov organic tin formulation thiab calcium-zinc formulation rau zus tau tej cov PVC granules nyob rau hauv PVC yeeb nkab fittings ua, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb, kev xav txog nqi, thiab kev txhawj xeeb ntawm ib puag ncig.Organic tin formulation muab kev ruaj ntseg kub thiab zoo lubrication tab sis muaj kev cuam tshuam ib puag ncig thiab tus nqi.Calcium-zinc formulation muab ib qho kev xaiv zoo rau ib puag ncig thiab raug nqi tab sis tej zaum yuav muaj kev txwv ntawm kev ruaj ntseg kub thiab kev sib tw ua haujlwm.Thaum kawg, kev xaiv ntawm formulation yog nyob ntawm qhov kev xav tau tshwj xeeb thiab qhov tseem ceeb ntawm cov chaw tsim khoom.
