MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), i kapa ʻia ʻo MOCA, he mea ia i hoʻohana ʻia ma ke ʻano he crosslinking agent / chain extender no nā huahana polyurethane, ʻoi aku hoʻi no ka cast polyurethane elastomers (CPU). He maʻalahi ka polyurethane elastomers a loaʻa i ke ʻano elasticity e like me ka rubber akā me nā waiwai koʻikoʻi, hoʻohui ia i ka elasticity kiʻekiʻe o ka ʻōpala a me ka paʻakikī o ka plastic. Nā hiʻohiʻona MOCA me ke kūpaʻa kala i ka wela kiʻekiʻe. Maikaʻi nā elastomers MOCA-base no ka abrasion / hopena / kemika / ʻaila / ozone a me ke kū anuanu, elasticity me ka paʻakikī kiʻekiʻe a haʻahaʻa paha (Shore A a i Shore D rating), kiʻekiʻe tensile / waimaka / ikaika hoʻopiʻi, a me ka absorption o ka haʻalulu. Me ka lōʻihi o ke ola o ka ipuhao, he maʻalahi loa ia e hoʻohana me, hiki iā ʻoe ke hana me ka lima ma mua o nā mīkini. Ma muli o kēlā mau waiwai kino a me nā pōmaikaʻi, ʻo MOCA ka mea maʻamau o ka crosslinking / chain extender no nā urethane elastomers (TDI system). Eia nō naʻe, he mea lapaʻau hoʻomalu honua no nā huahana Epoxy.
Ke hoʻohālikelike nei iā DETDA & DMTDA, aia kekahi mau mea maikaʻi o MOCA e like me kēia.
1. ʻOi aku ka māmā o ka hua i hoʻopau ʻia.
2. He ʻano paʻa ʻo MOCA, no laila, ʻoi aku ka maʻalahi o ka mālama ʻana a emi ʻole ka pollution.
3. Maʻalahi e mālama. Ola pot lōʻihi.
4. ʻOi aku ke kiʻekiʻe o Modulus.
5. Kumukuai haahaa.
ʻO MOCA kahi mea hoʻonui kaulahao diamine aromatic kaulana a i ʻole mea hoʻōla no ka hoʻolei ʻana i nā elastomers polyurethane (PU). He mau waiwai maikaʻi loa ka MOCA-base elastomers, hoʻohana nui ʻia i nā wahi like ʻole e like me ke kūkulu ʻana, ke kūkulu hale, nā kaʻa, ka mining, semi-conductor, epoxy, hale haʻuki a pēlā aku.
1. ʻO ka ʻoihana hoʻopili no ka ʻoihana uila.
2. Waiwai / uhi no ke kūkulu 'ana a me ka hana hale.
3. Hoʻonui kaulahao no nā elastomers PU, ʻo ia hoʻi ka hoʻopili ʻana i ka lāʻau ʻāʻī, PU spider.
4. Mea ho'ōla no ka resin epoxy.
5. Nā ʻāpana no ka hoʻohana ʻana i ka ʻoihana, ʻo ia hoʻi nā kāʻei conveyor, casters, alakaʻi wili, hui pū.
6. ʻO nā pads absorption shock no ka ʻoihana kaʻa.
7. Pa'i 'olola, pahu pahu, squeegee blades, ho'oma'ema'e maka, scraper blades no ka pa'i 'oihana.
8. Mea hoʻopaʻa.
9. Epoxy insulation mea.
10. Pepa urethane antibacterial.
11. Pale hoʻokaʻawale mineral.
12. Paipu paipu.
Hoʻopili:25 kg/fiber pahu 200 kg/fiber pahu
