Daim Ntawv Thov Pigment Carbon Black

Kev thov tiv thaiv UV

Ib qho ntawm kev siv cov pa roj carbon dub hauv kev lag luam yas yog txhawm rau tiv thaiv ultraviolet teeb lub hnub nyoog. Vim tias cov pa roj carbon dub muaj lub teeb pom kev zoo, nws tuaj yeem tiv thaiv tau cov yas los ntawm kev tshav ntuj los tsim cov duab-oxidative kev puas tsuaj. Lub luag haujlwm ntawm cov pa roj carbon dub ua UV ruaj khov hauv cov yas suav nrog: hloov lub zog hluav taws xob ua cua sov; tiv thaiv cov yas nto los ntawm hluav taws xob ntawm qee qhov nthwv dej; cuam ​​tshuam cov pab pawg atomic los tsim cov tshuaj tiv thaiv kev laus, yog li tiv thaiv kev puas tsuaj catalytic. Ultraviolet rays tshwj xeeb yog teeb meem rau polyolefins. Kev ntsuam xyuas tau pom tias thaum lub siab ntawm qhov ua tau zoo ntawm cov pa roj carbon dub yog 2%, kev ua kom zoo UV tiv thaiv tuaj yeem ua tiav.

Kev tiv thaiv cov pa roj carbon dub ntawm UV kev laus ntawm cov yas yog nyob ntawm qhov loj me me, cov qauv thiab cov tshuaj lom neeg ntawm cov pa roj carbon dub.

Thaum qhov loj me ntawm cov pa roj carbon dub me me, vim thaj chaw nce ntxiv, nws lub peev xwm nqus tau lub teeb lossis ntxoov ntxoo nce ntxiv, yog li UV tiv thaiv kev ua kom zoo dua qub, tab sis qhov loj me me tsawg dua 20nm, thiab nws qhov kev tiv thaiv zoo li ua rau tib qib. Qhov laj thawj yog tias thaum qhov loj me me dhau, thim rov qab Cov tawg tawg tau raug txo, thiab lub teeb uas txuas mus tom ntej cuam tshuam rau kev ruaj ntseg ntawm cov polymer.

Cov qauv qis dua, uas yog, thaum qhov loj me ntawm qhov sib sau ua ke me me, vim tias qhov ntim ntawm qhov sib npaug ntawm qhov sib txuam me dua, qhov kev tiv thaiv ntawm cov polymer yuav ua kom zoo dua. Qhov no kuj yog qhov laj thawj vim li cas cov pa roj carbon dub nrog cov qauv qis dua yog qhov tsaus dua.

Cov pa roj carbon dub muaj ntau cov pa muaj cov pa nyob saum nplaim dej, uas yog, thaum cov ntsiab lus hloov pauv tau siab dua, nws tuaj yeem tshem tawm cov noob tsim thaum lub polymer tawg, yog li kev tiv thaiv kuj tseem txhim kho.

Txhaj tshuaj masterbatch tau muab faib ua qib siab thiab zoo tib yam

Cov qib qib masterbatch feem ntau yog siv hauv cov thawv ntim cov tshuaj pleev ib ce, ABS rau cov tsheb, cov khoom siv tawv PVC qib siab, cov khoom siv hauv tsev thiab lwm yam khoom lag luam qib siab. Nws xav tau cov xim masterbatch los siv cov xim kom sib npaug sib npaug, tshwj xeeb tshaj yog rau cov khoom lag luam xim yam tsis muaj xim me me thiab xim. Cov pa roj carbon dub yuav tsum yog cov xim dub nrog cov xim me me thiab cov qauv qis, vim tias qhov dub feem ntau yog ua raws qhov nqus ntawm lub teeb, qhov me me qhov me me, siab dua lub teeb nqus, ua rau lub teeb qis dua, siab dua qhov dub, thiab cov khoom feem ntau yog xim dub. kaj.

Ordinary masterbatch feem ntau yog siv rau PE hnab khib nyiab, txuas, kav dej thiab lwm yam khoom lag luam. Cov yeeb yaj kiab qib siab xav tau cov xim me me thiab kev faib ua ke. Yuav tsum tsis txhob muaj xim taw tes ntau dua 0.6mm ntawm zaj duab xis. Cov yeeb yaj kiab uas siv tau tuaj yeem siv nrog qhov loj me me. , Ordinary pigment carbon black nrog cov qauv siab dua, nruab nrab dub thiab siv tau zoo dua tuaj yeem siv tau.

Fiber ntau masterbatch feem ntau muab faib ua polypropylene thiab polyester. Feem ntau siv cov tshuaj fiber ntau cov ntaub plaub, cov ntaub pua tsev, cov ntaub tsis-ntaub, thiab lwm yam. Cov pa roj carbon dub yuav tsum muaj kom muaj kev huv siab, muaj kev sib kis tau zoo, muaj lub zog tinting siab, tsis muaj impurities, thiab cov xim muaj xim tsawg dua 1um.
