Calcium-zinc stabilizer yog tsim los ntawm cov txheej txheem sib xyaw ua ke nrog calcium, zinc ntsev, lubricants, antioxidants, thiab lwm yam raws li cov khoom xyaw tseem ceeb. Nws tuaj yeem tsis tsuas yog hloov cov teeb meem stabilizers xws li lead-cadmium ntsev thiab organotins, tab sis kuj muaj cov cua sov zoo heev, kev ntseeg siab ntawm lub teeb, lub teeb xa hluav taws xob thiab xim lub zog. Cov kev paub dhau los tau ua pov thawj tias hauv cov khoom siv PVC, cov khoom tsim thiab kev ua haujlwm yog qhov zoo, thiab cov nyhuv thermal stabilization yog sib npaug rau cov hmoov txhuas ntsev stabilizers, uas yog ib qho zoo heev uas tsis muaj tshuaj lom stabilizer.
Rigid PVC calcium-zinc stabilizer
Cov tsos mob tseem ceeb ntawm calcium thiab zinc stabilizer yog mis nyuj dawb hmoov, lumpy thiab puree zoo li. Powdered calcium thiab zinc stabilizers yog siv los ua ntau yam tsis muaj tshuaj lom PVC stabilizer, feem ntau siv rau hauv cov khoom ntim khoom noj, tshuab kho mob, cables thiab xov hlau, thiab lwm yam. Nyob rau theem no, PVC calcium-zinc stabilizers tuaj yeem siv rau cov yeeb nkab fittings. twb tshwm sim nyob rau Suav teb lawm.
Calcium-zinc stabilizers hloov cov ntsev ntsev thiab yuav tsum daws qhov teeb meem
Vim tias cov khoom siv PVC cov khoom siv niaj hnub yog ib qho kev pabcuam rau kev tsim thiab ua cov hlau lead ntsev stabilizers, txawm tias muaj cov roj nplua nyeem txaus ntxiv, nws tsis tuaj yeem tiv thaiv cov epoxy resin ntxiv rau lub sijhawm txaus, thiab rhuav tshem cov qub ntub dej sib npaug. Nws yog ib qho teeb meem nyuaj rau cov calcium-zinc stabilizers los cuam tshuam nrog kev hloov cov ntsev ntsev.
Yuav ua li cas txhim kho lub wettability ntawm calcium-zinc stabilizer thiab nce tus nqi extrusion raws li kev txhim kho lubricant
Lub lubricant dav siv nyob rau hauv lub teb los yog waxes uas tsis tshua muaj molecular qauv thiab polyethers yog dominant, thiab qhov zoo dua yog cov moisturizing nyhuv yog zoo heev, uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm feem ntau cov teb, tab sis rau cov rooj tog uas nyob rau hauv kev sib cuag nrog lub lub cev, xws li cov xim tsis muaj xim board ntug banding, thiab lwm yam, yuav muaj nag lossis daus tom qab lub sijhawm ntev, ua rau qias neeg thiab nplaum, uas ua rau muaj kev phom sij rau cov khoom siv thiab kov ntawm cov khoom, thiab cov roj nplua nyeem nrog cov qauv molecular tsawg yog txwv los ntawm tus nqi ntxiv, thiab ntau nws yog precipitated, yog li ntawd peb tau tsim thiab tsim ib tug high-efficiency lubricant silicone wax khoom uas tsis tshua muaj melting point, zoo wettability, tsis muaj nag lossis daus, thiab yuav tsis raug txwv los ntawm tus nqi ntxiv, thiab qhov tseeb. cov nyhuv ntawm cov quav ciab dav dav tuaj yeem ua tiav nrog qhov me me ntawm qhov sib ntxiv, thiab qhov zoo dua yog tias nws tsis ua kom dej nag, thiab cov khoom zoo tuaj yeem txhim kho thaum txhim kho kev tsim khoom thiab kev ua haujlwm thiab txhim kho cov khoom tsim tau.
