MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4 '- Methylenebis (2-chloroaniline), ti a tun pe ni MOCA, jẹ nkan ti a lo bi oluranlọwọ crosslinking / pq extender fun awọn ọja polyurethane, paapaa fun awọn elastomer polyurethane simẹnti (CPU). Polyurethane elastomers jẹ rọ ati posse elasticity iseda bi roba ṣugbọn pẹlu awọn ohun-ini pataki, o daapọ rirọ giga ti roba ati rigidity ti ṣiṣu. Awọn ẹya MOCA pẹlu iduroṣinṣin awọ ni iwọn otutu giga. MOCA-base elastomers dara fun abrasion / ikolu / kemikali / epo / ozone ati resistance otutu, rirọ laibikita pẹlu giga tabi lile lile (Idiwọn Shore A si Shore D), fifẹ giga / yiya / agbara funmorawon, ati gbigba gbigbọn. Pẹlu igbesi aye ikoko gigun, o rọrun pupọ lati mu pẹlu, o le paapaa mu pẹlu ọwọ dipo awọn ẹrọ. Abajade lati awọn ohun-ini ati awọn anfani ti ara wọnyẹn, MOCA jẹ ọna asopọ ọna asopọ / pq ti o wọpọ julọ fun awọn elastomers urethane (eto TDI). Nibayi, o tun jẹ aṣoju imularada gbogbo agbaye fun awọn ọja Epoxy.
Ni afiwe si DETDA & DMTDA, awọn anfani ti o han gbangba wa ti MOCA bi atẹle.
1. Ọja ti pari jẹ fẹẹrẹfẹ ni awọ.
2. MOCA jẹ iru ti o lagbara, nitorinaa, o rọrun pupọ lati tọju ati dinku idoti.
3. Rọrun lati mu. Igbesi aye ikoko gigun.
4. Modulu ga ju.
5. Iye owo kekere.
MOCA jẹ olutọpa ẹwọn diamin aromatic ti a mọ daradara tabi aṣoju imularada fun simẹnti polyurethane (PU) elastomer. MOCA-base elastomers ni awọn ohun-ini ti o dara julọ, ni lilo pupọ ni awọn agbegbe pupọ pẹlu ikole, ile, awọn ọkọ ayọkẹlẹ, iwakusa, adaorin ologbele, iposii, ohun elo ere idaraya ati bẹbẹ lọ.
1. Bridging oluranlowo fun itanna ile ise.
2. Ohun elo ti ko ni omi / ibora fun ikole & ile-iṣẹ ayaworan.
3. Pq extender fun PU elastomers, ie bakan roba coupling, PU Spider.
4. Curing oluranlowo fun iposii resini.
5. Awọn paati fun lilo ile-iṣẹ, ie awọn beliti gbigbe, casters, rollers guide, couplings.
6. Awọn paadi gbigba mọnamọna fun ile-iṣẹ adaṣe.
7. Awọn rollers titẹ sita, awọn abẹfẹlẹ ilu, awọn abẹfẹlẹ squeegee, awọn abẹfẹ mimọ, awọn abẹfẹlẹ scraper fun ile-iṣẹ titẹ sita.
8. Ohun elo lilẹ.
9. Awọn ohun elo idabobo iposii.
10. Antibacterial urethane dì.
11. Iboju Iyapa erupe.
12. Pipe lining.
