ʻO ke kumukūʻai maikaʻi loa ʻo Desmodur RE no nā mea hoʻopili CAS 2422-91-5 Triphenylmethane -4,4`,4“-triisocyanate/ Methylidintri-p-phenylene triisocyanate
He mea hoʻopili ʻoi loa kā mākou RE, Hoʻohana ʻia i loko o nā mea hoʻopili i hana ʻia e ka polyurethane hydroxyl, ka rubber kūlohelohe a i ʻole synthetic, he ikaika hoʻopili maikaʻi loa ia i ka rubber a hiki ke hoʻohana ʻia i loko o ka resin, antioxidant, plasticizing agent, pressure-sensitive etc. Hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o BAYER's Desmodur RE.
Nā kikoʻī huahana:
Inoa Kemika: Triphenylmethane-4,4',4''-triisocyanate
Formula Molekala: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
ʻAno: mea hana
ʻAno hoʻonohonoho: HC[NCO]3
Ka nui o ke kaumaha: 1.0g/c m3, 20℃
Kiko heheʻe: 89 ℃
ʻO kā mākou RE, i kapa ʻia hoʻi ʻo TTI, he hopena ia e loaʻa ana he 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate a me 72.5% ethyl acetate. He mea hoʻōla honua / crosslinker no ka mea hoʻopili e pili ana i ka hydroxyl polyurethane, nā ʻōpala kūlohelohe a me nā synthetic, maikaʻi loa no ka hoʻopili ʻana i nā mea ʻōpala. Hoʻohana nui ʻia no ka hoʻopili ʻana i nā metala me ka ʻōpala. Eia kekahi, hiki ke hoʻopili ʻia ʻo RE ma ka resin, antioxidant, plasticizer, a pēlā aku. Ma ke kahua hoʻopili, hoʻopili ʻia ʻo RE ma ke ʻano he mea hoʻopili ma ka neoprene adhesive a/a i ʻole p hydroxyl polyurethane adhesive ma nā wahi kāmaʻa. Ma ke ʻano laulā, no ka hoʻōla ʻana i ka mea hoʻopili o 100 mau ʻāpana ma ke kaumaha (pbw) e pili ana i ka nui i ʻōlelo ʻia o 4-7 pbw RE. ʻO ke ola ipu o ka mea hoʻopili i hui ʻia ma kahi o nā hola.
Pono e hoʻohana ʻia ka mea hoʻopili ʻelua ʻāpana i loko o ka manawa kūpono ma hope o ke kau ʻana iā RE. ʻAʻole pili wale ka lōʻihi o ka manawa kūpono i ka nui o ka polymer o ka mea hoʻopili, akā ʻo nā ʻāpana pili ʻē aʻe (e like me ka resin, antioxygen, plasticizer, solvent, etc. Ke kokoke i ka manawa kūpono, maʻamau he mau hola a i ʻole hoʻokahi lā hana, lilo ka mea hoʻopili i mea paʻakikī ke hana, a piʻi koke ka viscosity. ʻO ka hope loa, lilo ia i jelly hiki ʻole ke hoʻihoʻi ʻia. 100 ka mea hoʻopili maikaʻi, Hydroxyl polyurethane (ʻO ka Polyurethane account no kahi o 20%), RE dose 4-7. Chloroprene rubber (ʻO ka Rubber account no kahi o 20%), Hana kā mākou RE i 4-7.
Hoʻopili ʻana:
750g/ʻōmole, 20 ʻōmole i loko o hoʻokahi pahu, 24 a i ʻole 30 mau pahu i loko o hoʻokahi pallet;
20kg/pahu, 18 pahu a i ʻole 27 pahu i loko o hoʻokahi pallet;
55kg/pahu, 8 a i ʻole 12 mau pahu i loko o hoʻokahi pallet;
180kg/pahu, 4 pahu i loko o hoʻokahi pallet
Ka Waihona:
E mālama ʻia i loko o ka ipu paʻa mua ma lalo o 23℃, hiki ke mālama ʻia nā huahana no 12 mau mahina. He mea maʻalahi loa ia i ka ʻili; e hoʻopuka ʻia ka carbon dioxide a me ka urea hiki ʻole ke hoʻoheheʻe ʻia i ka wā e hana ai me ka wai. Inā ʻike ʻia i ka ea a i ʻole ka mālamalama, e wikiwiki ia i nā loli kala, akā ʻaʻole e hoʻopilikia ʻia ka hana pono.
