Nws yog ib hom siab molecular hnyav hindered phenolic antioxidant, nrog zoo compatibility nrog resin, extraction kuj, tsis tshua muaj volatilization, siab oxygen kuj efficiency thiab zoo hluav taws xob rwb thaiv tsev. Nws yog qhov tsim nyog rau kev ruaj ntseg ntawm cov pa oxygen ntawm ntau yam polymers thiab cov ntaub ntawv organic, tshwj xeeb tshaj yog nrog phosphite, thioester, benzofuranone, carbon radical capture agent thiab lwm yam auxiliary antioxidant. Nyob rau hauv high kub ua thiab siab extraction kuj daim ntaub ntawv los muab cov khoom zoo heev ua stability thiab zoo kav ntev stability.
Daim ntawv thov teb suav nrog polyolefin, PET thiab lwm yam thermoplastic polyester thiab PBT, polyamide, styrene resin thiab elastomer cov ntaub ntawv xws li polyurethane thiab roj hmab ntuj. Tshwj xeeb tshaj yog tsim rau high-temperature processing ntawm polyolefin (xws li PP, PE, thiab lwm yam) yeeb nkab, txhaj tshuaj molding khoom, hlau thiab cable thiab lwm yam khoom ua teb. Tsis tas li ntawd, vim nws tsis muaj tshuaj lom, tsis muaj kuab paug, tuaj yeem tswj tau cov xim zoo ntawm cov yas, yog li nws tuaj yeem siv rau hauv kev sib cuag nrog cov khoom ntim khoom noj.
Ntxiv tus nqi: feem ntau 0.05% -1.0%, qhov tshwj xeeb ntxiv tus nqi txiav txim siab raws li tus neeg siv khoom thov kev xeem.
Ntim hauv 20 Kg / 25 Kg kraft ntawv hnab lossis thawv.
Khaws kom tsim nyog hauv qhov chaw qhuav, qhov cua zoo hauv qab 25 C kom tsis txhob muaj kev sib cuag nrog cov khoom siv hluav taws xob. Lub neej txee yog ob xyoos
