Kev Siv
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) yog ib qho organic compound, thiab nws cov kev siv tseem ceeb yog raws li nram no:
- Kev Tsim Cov Khoom Siv Polyurethane: MOCA yog ib qho tseem ceeb rau cov saw hlau polyurethane elastomers. Hauv kev tsim cov polyurethane, isocyanate prepolymers yuav tsum tau ua haujlwm nrog cov saw hlau extenders los tsim cov polyurethane polymers uas muaj molecular hnyav. MOCA muaj kev ua haujlwm siab nrog isocyanates, uas tuaj yeem ua kom cov saw hlau polyurethane molecular ntev dua thiab txhim kho qhov nyuaj, lub zog, kev hnav tsis kam, kev tsim kua muag tsis kam thiab lwm yam khoom ntawm cov khoom. Nws feem ntau siv rau hauv kev tsim cov khoom polyurethane elastomer uas muaj kev thauj khoom siab, xws li cov phaj sieve, cov menyuam roj hmab, cov ntsaws ruaj ruaj, thiab lwm yam siv hauv kev lag luam xws li kev khawb av, metallurgy, thiab roj av. Cov khoom no yuav tsum muaj kev hnav tsis kam zoo thiab cov khoom siv kho tshuab.
- Tus Neeg Sawv Cev Kho Rau Epoxy Resins: MOCA siv tau ua tus neeg sawv cev kho rau epoxy resins. Nws dhau los ntawm kev sib txuas lus nrog epoxy resins los tsim cov qauv network peb-seem, yog li kho cov epoxy resins. Cov epoxy resins kho tau muaj cov khoom siv kho tshuab zoo, tiv taus kev xeb tshuaj lom neeg, thiab tiv taus cua sov. Nws feem ntau siv rau hauv kev tsim qee cov epoxy composites nrog cov kev xav tau kev ua haujlwm siab, xws li hauv cov teb ntawm cov khoom siv hluav taws xob potting thiab cov txheej hauv pem teb. Cov khoom siv hluav taws xob potting yuav tsum tiv thaiv cov khoom siv hluav taws xob sab hauv los ntawm ib puag ncig sab nraud. Cov epoxy resin kho nrog kev koom tes ntawm MOCA tuaj yeem muab kev sib khi zoo thiab kev tiv thaiv tshuab. Cov txheej hauv pem teb epoxy yuav tsum muaj cov khoom xws li kev tiv taus hnav thiab tiv taus xeb kom tau raws li qhov xav tau ntawm kev siv ntawm cov chaw xws li cov chaw ua haujlwm hauv kev lag luam thiab chaw nres tsheb.
Ntim thiab Xa Khoom
25KG/hnab los yog raws li cov neeg siv khoom xav tau.
Kev xa khoom: 6.1 hom khoom txaus ntshai thiab tuaj yeem xa los ntawm dej hiav txwv.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
