Yihoo Uv571 yog 100% sib npaug khoom ntawm qhov ntawd los ntawm cov tuam txhab, nrog ruaj khov thiab lub teeb xim. Piv nrog cov khoom siv tib yam, cov xim ntawm cov khoom tsuas muaj qhov sib txawv me me tsis pub dhau rau lub hlis.
UV571 yog lub teeb pom kev daj ua kua, tsuas yog nqus 300nm-350nm spectrum. Raws li cov kev thov ua tiav tiag tiag, Yihoo UV571 tau siv nyob rau hauv cov liaj zoo li pU mos foaming, PU txheej thiab txheej ua rau muaj teeb meem kev laus. Nws tau pom zoo tias Yihoo UV571 tuaj yeem yog qhov hloov pauv zoo tshaj plaws rau cov khoom lag luam los ntawm cov tuam txhab. Kev nqus cov spectra ntawm UV571 yog raws li ua raws:
Los ntawm nws qhov kev ua tau zoo, UV 571 yog qhov tsim nyog rau:
1. Tswvyim Polyurethane, txheej thiab tus kheej-peeling pvc, pvdc, thermoh, PA, Pur, Pur Cast tiav. Nws kuj yog qhov haum rau looj, cov nplaum, cov nplaum, homopolymer / copolymer styrene, elastomer thiab polyolefin.
2.Txhua kom yaj nyob rau ntau yam ntawm cov kuab tshuaj, monomers thiab intermediates, yooj yim rau emulsify hauv dej-raws cov nplaum; Nws kuj tseem siv tau rau polymerization thiab PVC ntawv.
3.UV571 muaj kev sib haum zoo nrog cov ntaub ntawv feem ntau, thiab nws cov khoom siv tsis tau muaj peev xwm tsawg, yog li ua UV571 kev tiv thaiv zoo heev rau cov khoom siv hluav taws xob.
4.Can siv nrog lwm cov kev sib ntxiv, xws li phenolic antioxidants (piv txwv li sulfide, phosphat, sulfide, phev. LS1135) kom ua tiav cov nyhuv zoo dua.
Qhov sib piv ntau ntawm UV571, nyob ntawm seb hom khoom siv hauv paus thiab kev ua tau zoo ntawm cov khoom kawg, yog li ntawm 0.2% thiab 5.0%:
Rau PU, raws li kev ua haujlwm thiab ntev lub teeb ruaj khov yuav tsum tau, UV571 tuaj yeem ntxiv ntawm 0.2% thiab 0.5%;
Rau PVC, UV571 tuaj yeem ntxiv ntawm 0.3% thiab 0.5%. Cov piv txwv ntxiv rau Co-Extruded PVC tuaj yeem nce li 5%.
