MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), eo hape e bitsoang MOCA, ke ntho e sebelisoang e le "crosslinking agent / chain extender" bakeng sa lihlahisoa tsa polyurethane, haholo-holo bakeng sa li-cast polyurethane elastomers (CPU). Li-elastomer tsa polyurethane lia tenyetseha 'me li na le tlhaho ea elasticity joalo ka rabara empa li na le thepa ea bohlokoa, li kopanya elasticity e phahameng ea rabara le ho tiea ha polasetiki. Likarolo tsa MOCA tse nang le botsitso ba mebala ka mocheso o phahameng. Li-elastomers tsa MOCA-base li molemo bakeng sa abrasion / impact / chemical / oil / ozone le serame se batang, elasticity ho sa tsotellehe hore na ho na le boima bo phahameng kapa bo tlaase (Shore A to Shore D rating), matla a phahameng a tensile / tabo / compression, le ho kenngoa ha vibration. Ka bophelo bo bolelele ba pitsa, ho bonolo haholo ho sebetsana le eona, o ka khona ho sebetsana le eona ka letsoho ho fapana le mechini. Ka lebaka la thepa eo ea 'mele le melemo, MOCA ke eona e atileng ka ho fetesisa ea ho tšela / ketane bakeng sa urethane elastomers (TDI system). Ho sa le joalo, e boetse ke pheko ea bokahohle bakeng sa lihlahisoa tsa Epoxy.
Ha ho bapisoa le DETDA & DMTDA, ho na le melemo e meng e hlakileng ea MOCA ka tsela e latelang.
1. Sehlahisoa se phethiloeng se bobebe ka 'mala.
2. MOCA ke mofuta o tiileng, kahoo, ho bonolo haholo ho boloka le ho fokotsa tšilafalo.
3. Ho bonolo ho sebetsana le eona. Bophelo bo bolelele ba pitsa.
4. Modulus e phahame.
5. Theko e tlaase.
MOCA ke sesebediswa se tsebahalang sa diamine chain extender kapa se alafa bakeng sa ho lahla polyurethane (PU) elastomers. Li-elastomers tsa MOCA-base li na le thepa e ntle haholo, li sebelisoa haholo libakeng tse fapaneng ho kenyelletsa kaho, meaho, likoloi, merafo, semi-conductor, epoxy, setsi sa lipapali joalo-joalo.
1. Moemeli oa borokho bakeng sa indasteri ea elektroniki.
2. Lintho tse sa keneleng metsi / koae bakeng sa indasteri ea kaho le ea meralo.
3. Chain extender bakeng sa PU elastomers, ke hore, ho kopanya rabara ea mohlahare, sekho sa PU.
4. Moemeli oa pheko bakeng sa resin ea epoxy.
5. Likarolo tsa tšebeliso ea indasteri, ke hore mabanta a conveyor, li-caster, li-roller, li-couplings.
6. Lipampiri tsa ho monya ho ts'osoang bakeng sa indasteri ea likoloi.
7. Lirolara tsa khatiso, li-drum blades, li-squeegee blades, li-blades tsa ho hloekisa, li-scraper blades bakeng sa indasteri ea khatiso.
8. Thepa ea ho tiisa.
9. Epoxy insulation material.
10. Letlapa la antibacterial urethane.
11. Skrine ea karohano ea liminerale.
12. Lithako tsa liphaephe.
Ho paka:25 lik'hilograma / moropa oa fiber 200 kg / moropa oa fiber
Ho monya ha mongobo hanyenyane; qoba ho kopana le metsi. E-ba hōle le khanya ea letsatsi.
