Lub luag haujlwm ntawm calcium zinc stabilizer hauv cov khoom pvc yog dab tsi?

Calcium thiab zinc stabilizer yog synthesized los ntawm cov txheej txheem sib xyaw tshwj xeeb nrog calcium ntsev, zinc, roj nplua nyeem thiab antioxidant ua cov khoom tseem ceeb. Nws tsis tsuas yog hloov cov ntsev ntawm cov hlau lead thiab cadmium thiab cov tshuaj lom neeg stabilizers xws li organotin, tab sis kuj muaj kev ruaj khov thermal zoo, lub teeb ruaj khov thiab pob tshab nrog rau xim muaj zog. Kev xyaum Ca-Zn stabilizer tau ua pov thawj tias hauv cov khoom PVC resin, kev ua haujlwm ua tiav thiab kev ruaj khov thermal yog sib npaug rau cov hlau lead ntsev stabilizer, uas yog cov tshuaj zoo tsis muaj tshuaj lom.

Cov tsos ntawm calcium zinc stabilizer yog feem ntau yog hmoov dawb, flake, muab tshuaj txhuam.

Calcium zinc stabilizer yog siv dav hauv kev ua thiab tsim cov khoom pvc, thiab cov khoom pvc tsim tawm muaj ntau yam khoom zoo heev. Cov hauv qab no piav qhia txog lub luag haujlwm tshwj xeeb ntawm calcium thiab zinc stabilizers:

1, tuaj yeem hloov cov organotin stabilizer thiab cov ntsev ua kom cov ntsev ruaj khov, kom ua tau raws li cov kev cai tsis muaj tshuaj lom rau kev noj qab haus huv ntawm cov hlau thiab cable;

2, nrog rau qhov pib zoo heev thiab thermal stability, anti-sulfide pollution;

3, calcium zinc stabilizer muaj lubricity zoo thiab cov nyhuv sib txuas tshwj xeeb, yog li ntawd cov khoom muab tub lim muaj kev sib kis zoo, txhim kho cov ntim khoom resin, txhim kho kev ua haujlwm ntawm cov khoom, txo cov khoom siv kho tshuab, thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv;

4, ob qho tib si toughening thiab txhawb nqa lub luag haujlwm ntawm melting, plasticizing fluidity yog qhov zoo;

5, tuaj yeem ua rau cov khoom sib xyaw PVC muaj cov yas zoo sib xws thiab cov dej ntws ceev ceev, yog li ntawd cov khoom nto du.

Zinc stabilizer yog ib qho khoom siv ua kua calcium zinc compound thermal stabilizer uas zoo rau ib puag ncig thiab ua haujlwm tau zoo. Kev ruaj khov thermal zoo heev thiab pob tshab, tsis muaj qhov tshwm sim ntawm cov dej nag thiab kev tsiv teb tsaws chaw rau cov khoom PVC, thiab zoo dua nrog cov roj tiv taus cua sov, epoxy methyl ester, calcium zinc stabilizer thiab epoxy soybean roj. Haum rau kev ua cov tshuaj nplaum PVC, siv dav hauv slush, yas, yas thiab lwm yam thev naus laus zis PVC.

Calcium zinc stabilizer tsis yog tsuas yog muaj kev sib raug zoo thiab kev tswj viscosity zoo, tab sis kuj muaj xim pib zoo thiab khaws xim.

Cov khoom no tau ua pov thawj tias yog ib qho khoom siv tiv thaiv cua sov zoo heev. Kev sib raug zoo, kev hloov pauv tsawg, kev ntws tsawg, kev tiv taus lub teeb zoo, tsim nyog rau cov yeeb nkab, cov khoom ua si, cov khoom siv thauj khoom, cov ntaub tshaj tawm, cov ntawv ntsa thiab lwm yam khoom lag luam PVC.
