Nkag siab PVC Stabilizers: Lub luag haujlwm ntawm Calcium-Zinc thiab Kev Xaiv

Polyvinyl chloride (PVC), ib qho ntawm feem ntau ntau yam thermoplastics, yog inherently tsis ruaj khov thaum raug cua sov, lossis kev ntxhov siab thaum ua thiab daim ntawv thov. Txhawm rau tawm tsam kev mob nkeeg, stabilizers yog qhov tseem ceeb ntxiv. Ntawm cov no, calcium-zinc (Ca-Zn) Stabilizers thiab cov taug txhuas stabilizers sawv cev rau ob txoj kev sib txawv, txhua tus muaj qhov zoo thiab cov nyom.

1. Cov tawv nqaij ua kom ruaj khov: qhov ua tau zoo tshaj plaws

Lead-bamed steeilizers, xws li Dibasic Lead Carbonate lossis Leadance, tau muaj kev ywj siab raws li lawv cov nqi-ua haujlwm ruaj khov. Lawv siv hluav taws xob hydrochloric acid (HCl) tso tawm thaum lub sijhawm PVC DEMITY, tiv thaiv autocatalytic. Txawm li cas los xij, lawv cov kev pheej hmoo thiab ib puag ncig muaj kev pheej hmoo tau ua rau cov kev cai nruj. Piv txwv li cov koom haum European Union (EU) 2023/293 txwv cov ntsiab lus txhuas hauv PVC mus <0.1%, ua kom nrawm nrawm rau kev hloov chaw nyab xeeb.

2. Calinc Stabilizers: Eco-Cov Kev Xaiv Tshiab

Calcium-Zinc Stabilizers, muaj ntawm calcium thiab zinc nyeem ntawv ua ke nrog cov organic acids, chaw txhawj xeeb ib puag ncig thiab kev txhawj xeeb txog kev noj qab haus huv. Lawv tsis muaj tshuaj lom, ua tau raws li cov cai thoob ntiaj teb (piv txwv li, mus txog thiab RoHS), thiab kho nrog cov hom phiaj ruaj khov. Cov txiaj ntsig tseem ceeb muaj xws li:

-Qhov khoom ruaj khov: Tiv thaiv kev txwv ua kom sov thaum lub sijhawm ntsuas kub siab (piv txwv li, extrusion lossis txhaj tshuaj molding).

-Uv Kuj: Tiv thaiv cov khoom PVC zoo li lub qhov rai profiles thiab sab nraum zoov caboration thiab huab cua.

-Qhov khoom: muaj nyob rau hauv cov qib tshwj xeeb, xws li cov kev ua zaub mov tshwj xeeb, thiab pob tshab ua kom zoo li kev tsim muaj kev tsim kho, tsheb, thiab ntim.

3. Kev ua haujlwm thiab kev ua lag luam

Thaum ua cov txheej txheem coj ua nthuav tawm marginally zoo dua thawj lub zog hluav taws xob, calinc tshuab tau kaw qhov kev ua tau zoo ntawm cov qauv zoo. Piv txwv li, cov symergies nrog co-stabilizers zoo li ntxhia acid scavengers txhim kho kev ua tau zoo. Lub ntiaj teb kev ua lag luam rau eco-seebster PVC Steeilizers, muaj nuj nqis rau $ 3.48 lab los ntawm kev tswj hwm 2023, yog npaj los ntawm kev tswj hwm nyiaj $ 3.43

4. Cov ntawv thov thiab yav tom ntej saib xyuas

Calcium-Zinc Stabilizers Dominate Dominate cov ntawv thov yuav tsum muaj kev nyab xeeb thiab durability:

-Covtruction: kav dej, lub qhov rai thav duab, thiab siding.

-TauNaurotive: Kev txiav caj dab sab hauv thiab ntsaws ruaj ruaj.

-Food ntim: Raws li cov yeeb yaj kiab thiab ntim. Tsis pub dhau R & d tsom xam rau kev ua kom zoo nqi-ua tau zoo thiab nthuav siv cov xwm txheej, xws li siv cov khoom siv hluav taws xob.

Kev hloov los ntawm cov txhuas raws cov txhuas raws li calcium-zinc stabilizers underscores lub pvc kev lag luam kev cog lus kom muaj kev ruaj khov. Thaum cov kev sib tw zoo li cov nqi pib siab dua, cov txiaj ntsig kev nyab xeeb ib puag ncig, thiab ntau yam ua tau zoo-zinc tshuab raws li yav tom ntej ntawm PVC ruaj khov. Raws li thev naus laus zis hloov zuj zus, cov stabilizers yuav ua ib lub luag haujlwm tseem ceeb hauv kev ua haujlwm rau greener, high-ua PVC cov khoom thoob.
