99% MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), tseem hu ua MOCA, yog ib yam khoom siv ua tus neeg sawv cev hla / saw txuas rau cov khoom polyurethane, tshwj xeeb tshaj yog rau cov polyurethane elastomers (CPU). Polyurethane elastomers muaj kev ywj pheej thiab muaj qhov elasticity zoo li roj hmab tab sis muaj cov yam ntxwv tseem ceeb, nws ua ke qhov elasticity siab ntawm roj hmab thiab kev ruaj khov ntawm yas. MOCA nta nrog kev ruaj khov xim hauv qhov kub siab. MOCA-base elastomers zoo rau kev puas tsuaj / kev cuam tshuam / tshuaj / roj / ozone thiab kev tiv taus txias, elasticity tsis muaj teeb meem nrog qhov nyuaj siab lossis qis (Shore A rau Shore D rating), siab tensile / tear / compression zog, thiab kev nqus ntawm kev co. Nrog lub sijhawm ntev, nws yooj yim heev rau kev tuav nrog, koj tuaj yeem tuav tes es tsis txhob siv tshuab. Los ntawm cov khoom siv lub cev thiab cov txiaj ntsig, MOCA yog qhov feem ntau crosslinking / saw txuas rau urethane elastomers (TDI system). Lub caij no, nws kuj yog tus neeg sawv cev kho rau cov khoom Epoxy.
Piv rau DETDA & DMTDA, muaj qee qhov zoo ntawm MOCA raws li hauv qab no.
1. Cov khoom tiav lawm yog xim sib dua.
2. MOCA yog hom khoom khov, yog li, nws yooj yim dua rau kev khaws cia thiab tsawg dua kev ua qias tuaj.
3. Yooj yim rau kev tuav. Lub lauj kaub siv tau ntev.
4. Modulus siab dua.
5. Tus nqi qis dua.
MOCA yog ib qho aromatic diamine saw extender lossis curing agent uas siv dav hauv casting polyurethane elastomers, elastomeric pavement cov ntaub ntawv, PU waterproof coatings, PU adhesives, PU foams, thiab lwm yam.
Cov MOCA-saw-extended PU elastomers siv dav hauv cov chaw suav nrog tshuab, tsev, tsheb, kev thauj mus los, kev lag luam mining, cov khoom siv hluav taws xob encapsulation thiab chaw ua si nawv, thiab lwm yam.
MOCA kuj tseem siv tau rau hauv kev kho epoxy resin.
Peb cov MOCA yog qib purity siab, cov kua MOCA yaj yog xim tsis muaj xim rau cov kua daj pob tshab, nws raug pom zoo kom siv rau hauv cov ntawv thov xws li lub log skateboard, polyurethane mov hulling roller, scraper, lub teeb
xim PU coatings, thiab lwm yam uas xav tau cov khoom zoo thiab yuav luag tsis muaj xim pob tshab hauv qhov tsos.
MOCA yog ib qho tshuaj txuas ntxiv lossis tus neeg sawv cev kho kom zoo rau kev casting polyurethane (PU) elastomers. MOCA-base elastomers muaj cov yam ntxwv zoo heev, siv dav hauv ntau qhov chaw suav nrog kev tsim kho, kev tsim kho, tsheb, kev khawb av, semi-conductor, epoxy, chaw ua si thiab lwm yam.
1. Tus neeg sawv cev txuas rau kev lag luam hluav taws xob.
2. Cov khoom siv tiv thaiv dej / txheej rau kev tsim kho thiab kev lag luam vaj tsev.
3. Cov saw hlau txuas rau PU elastomers, piv txwv li lub puab tsaig roj hmab txuas, PU kab laug sab.
4. Tus neeg sawv cev kho rau epoxy resin.
5. Cov khoom siv rau kev siv hauv kev lag luam, piv txwv li cov siv txoj siv conveyor, cov casters, cov menyuam qhia kev, thiab cov couplings.
6. Cov ntaub thaiv kev poob siab rau kev lag luam tsheb.
7. Cov menyuam luam ntawv, cov hniav nruas, cov hniav squeegee, cov hniav ntxuav, cov hniav scraper rau kev lag luam luam ntawv.
8. Cov khoom siv kaw.
9. Cov khoom siv rwb thaiv tsev epoxy.
10. Daim ntawv urethane tua kab mob.
11. Lub vijtsam sib cais cov zaub mov.
12. Cov yeeb nkab.
