99% MOCA 4,4′-Methylenebis (2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), nanone yitwa MOCA, ni ikintu gikoreshwa nk'ikintu gihuza imiyoboro / umuyoboro w'insinga ku bicuruzwa bya polyurethane, cyane cyane kuri elastomer za polyurethane zikozwe mu cyuma (CPU). Elastomer za polyurethane zirahindagurika kandi zifite imiterere yoroshye nk'umugozi ariko zifite imiterere ikomeye, zihuza ubushyuhe bwinshi bwa rubber n'ubukonje bwa pulasitiki. MOCA ifite ubushobozi bwo kudahinduka kw'amabara mu bushyuhe bwinshi. Elastomer za MOCA-base ni nziza mu gushwanyagurika / ingaruka / imiti / amavuta / ozone no kurwanya ubukonje, ubushyuhe bwinshi nubwo bwaba buri hejuru cyangwa buke (Shore A to Shore D rating), imbaraga nyinshi zo gukurura / gucika / gukanda, no kwinjiza umwuka uhindagurika. Kubera ko imara igihe kirekire, biroroshye cyane kuyikoresha, ushobora no kuyikoresha n'intoki aho kuyikoresha imashini. Bitewe n'iyo miterere n'ibyiza nyabyo, MOCA niyo ikoreshwa cyane mu gushwanyagurika / umuyoboro w'insinga kuri elastomer za urethane (TDI system). Hagati aho, ni ikintu gikoreshwa mu gushwanyagurika ku bicuruzwa bya Epoxy.
Ugereranyije na DETDA na DMTDA, hari ibyiza bimwe na bimwe bigaragara bya MOCA nk'ibi bikurikira.
1. Igicuruzwa cyarangiye gifite ibara ryoroheje.
2. MOCA ni ubwoko bukomeye, bityo, biroroshye cyane kuyibika kandi igabanya umwanda.
3. Byoroshye gufata. Biramba mu nkono.
4. Modulus iri hejuru.
5. Igiciro gito.
MOCA ni aromatic diamine chain extender cyangwa agent ivura ikoreshwa cyane mu gucukura elastomers za polyurethane, ibikoresho byo mu muhanda bya elastomeric, irangi ritazimira PU, kole za PU, ifuro rya PU, nibindi.
Elastomer za MOCA-extended PU zikoreshwa cyane mu bice birimo imashini, inyubako, ibinyabiziga, ubwikorezi, inganda z'ubucukuzi bw'amabuye y'agaciro, ibikoresho by'ikoranabuhanga n'ibigo bya siporo, n'ibindi.
MOCA ishobora kandi gukoreshwa mu gukaraba epoxy resin.
MOCA yacu ni nziza cyane, MOCA ishongeshejwe nta ibara cyangwa umuhondo ibonerana, ni byiza kuyikoresha mu buryo nk'ipine rya skateboard, icyuma gifunga umuceri cya polyurethane, icyuma gifunga umuceri, n'urumuri rworoheje.
irangi rya PU, nibindi bisaba imiterere myiza kandi bigaragara neza nta ibara.
MOCA ni uburyo buzwi cyane bwo kongerera ingufu diyamine cyangwa uburyo bwo gukaraba ibyuma bya polyurethane (PU) elastomers. Elastomers za MOCA zifite imiterere myiza, zikoreshwa cyane mu nzego zitandukanye harimo ubwubatsi, inyubako, imodoka, ubucukuzi bw'amabuye y'agaciro, semi-conductor, epoxy, imikino n'ibindi.
1. Umuhuza w’inganda zikora ibikoresho by’ikoranabuhanga.
2. Ibikoresho bidapfa amazi / gusiga irangi mu nganda z'ubwubatsi n'ubwubatsi.
3. Umunyururu wongeraho elastomer za PU, ni ukuvuga umunwa w'urukiramende, igitambaro cya PU.
4. Umuti uvura epoxy resin.
5. Ibikoresho bikoreshwa mu nganda, ni ukuvuga imikandara yo gutwara ibintu, imikandara, imigozi iyobora ibintu, imigozi ihuza ibintu.
6. Udupapuro two gufata impanuka mu nganda z'imodoka.
7. Imigozi yo gucapa, ibyuma by'ingoma, ibyuma byo gukaraba, ibyuma byo gusukura, ibyuma byo gukaraba byo mu nganda z'icapiro.
8. Ibikoresho byo gufunga.
9. Ibikoresho byo gukingira ibyuma bivamo epoxy.
10. Urupapuro rwa urethane rurwanya bagiteri.
11. Ikirahuri cyo gutandukanya amabuye y'agaciro.
12. Imiyoboro y'amazi.
