99% MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - I-Methylenebis (2-chloroaniline), ebizwa nangokuthi i-MOCA, iyinto esetshenziswa njenge-ejenti yokuxhumanisa / i-chain extender yemikhiqizo ye-polyurethane, ikakhulukazi kuma-elastomer e-polyurethane ahlanganisiwe (i-CPU). Ama-elastomer e-polyurethane aguquguquka futhi anokwakheka okunwebeka njengerabha kodwa anezakhiwo ezibalulekile, ahlanganisa ukuqina okuphezulu kwerabha nokuqina kwepulasitiki. Izici ze-MOCA zinokuqina kombala ekushiseni okuphezulu. Ama-elastomer e-MOCA-base alungele ukuguguleka / umthelela / amakhemikhali / uwoyela / i-ozone kanye nokumelana nokubanda, ukuqina kungakhathalekile ukuthi kunobunzima obuphezulu noma obuphansi (isilinganiso se-Shore A kuya ku-Shore D), amandla aphezulu okudonswa / ukudabuka / ukucindezela, kanye nokumuncwa kokudlidliza. Ngokuphila isikhathi eside kwebhodwe, kulula kakhulu ukuphatha ngayo, ungaphatha ngisho ngesandla esikhundleni semishini. Ngenxa yalezo zakhiwo nezinzuzo zomzimba, i-MOCA iyi-extender evame kakhulu yokuxhumanisa / i-chain extender yama-elastomer e-urethane (uhlelo lwe-TDI). Okwamanje, futhi iyi-ejenti yokwelapha ebanzi yemikhiqizo ye-Epoxy.
Uma kuqhathaniswa ne-DETDA kanye ne-DMTDA, kunezinzuzo ezithile ezisobala ze-MOCA kanje.
1. Umkhiqizo oqediwe unombala okhanyayo.
2. I-MOCA iqinile, ngakho-ke, kulula kakhulu ukuyigcina futhi ingcolisa kancane.
3. Kulula ukuyiphatha. Ihlala isikhathi eside ebhodweni.
4. I-Modulus iphakeme.
5. Intengo ephansi.
I-MOCA iyi-aromatic diamine chain extender noma i-ejenti yokwelapha esetshenziswa kabanzi ekubunjweni kwama-polyurethane elastomers, izinto zokwakha i-elastomeric, izembozo ezingangeni manzi ze-PU, izinamathiselo ze-PU, ama-PU foam, njll.
Ama-elastomer e-PU enwetshiwe nge-MOCA asetshenziswa kabanzi ezindaweni ezifaka phakathi imishini, izakhiwo, izimoto, ezokuthutha, imboni yezimayini, ukufakwa kwezingxenye ze-elekthronikhi kanye nezikhungo zezemidlalo, njll.
I-MOCA ingasetshenziswa futhi ekuphekeni i-epoxy resin.
I-MOCA yethu inezinga eliphezulu lokuhlanzeka, i-MOCA encibilikayo ayinambala kuya kophuzi uketshezi olubonakalayo, kunconywa ukuthi isetshenziswe ezinhlelweni ezifana nesondo le-skateboard, i-polyurethane rice hulling roller, i-scraper, ukukhanya
izembozo ze-PU zombala, njll. ezidinga isici esihle kanye nokubukeka okusobala okungenambala.
I-MOCA iyi-aromatic diamine chain extender noma i-ejenti yokwelapha eyaziwayo ye-casting polyurethane (PU) elastomers. Ama-MOCA-base elastomers anezakhiwo ezinhle kakhulu, asetshenziswa kabanzi ezindaweni ezahlukene okuhlanganisa ukwakhiwa, ukwakha, izimoto, ukumbiwa kwezimayini, i-semi-conductor, i-epoxy, indawo yezemidlalo njalo njalo.
1. I-ejenti yokuhlanganisa imboni kagesi.
2. Izinto ezingangeni manzi/ingubo yokugqoka yemboni yokwakha neyokwakha.
3. Isandisi seketanga sama-elastomer e-PU, okungukuthi i-jaw rubber coupling, i-PU spider.
4. I-ejenti yokwelapha i-epoxy resin.
5. Izingxenye zokusetshenziswa kwezimboni, okungukuthi amabhande okuhambisa, ama-caster, ama-guide rollers, ama-coupling.
6. Ama-shock absorption pads embonini yezimoto.
7. Amarola okuphrinta, ama-drum blades, ama-squeegee blades, ama-cleaning blades, ama-scraper blades embonini yokuphrinta.
8. Izinto zokuvala.
9. Izinto zokuvikela i-Epoxy.
10. Ishidi le-urethane elilwa namagciwane.
11. Isikrini sokuhlukanisa amaminerali.
12. Amapayipi angaphakathi.
Ukupakisha: 25 kg noma 50kg/isigubhu noma isikhwama sefayibha
Ukumuncwa okuncane komswakama; gwema ukuthintana namanzi. Gcina kude nokukhanya kwelanga.
