Desmodur RE / Isocyanate RE no nā mea hoʻopili CAS 2422-91-5
Hiki ke hoʻololi i ka lina pono Isocyanate RE i DESMODURE RE
Nā kikoʻī huahana:
Inoa Kemika: Triphenylmethane-4,4 ', 4' '- triisocyanate
Palapala Molecular: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Kaha: mea hana
Kūlana hana: HC [NCO] 3
Ka nui: 1.0g / c m3, 20 ℃
Kuhi hoʻoheheʻe: 89 ℃
ʻO kā mākou RE kahi mea hana loulou e pili ana i ke keʻa, hoʻohana ʻia i nā mea hoʻopili i hana ʻia e hydroxyl polyurethane, ʻāpana kūlohelohe a synthetic paha, he ikaika paʻa paʻa loa ia i ka pākeke a me ka cab e hoʻohana ʻia ai i ka resin, antioxidant, plasticizing agents, pressure-sensitive etc. hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o BAYER's Desmodur RE.
Pono e hoʻohana i ka lina ʻelua mau mea i loko o ka wā applicaable ma hope o ke kau ʻana iā RE. ʻAʻole pili ka lōʻihi o ka manawa pili i ka ʻike polymer o ka lina, akā ʻo nā mea ʻē aʻe e pili ana (e like me ke kēpau, antioxygen, plasticizer, solvent, a pēlā aku. Ke kokoke i ka wā kūpono, maʻamau i kekahi mau hola a i hoʻokahi lā hana, lina lilo i mea paʻakikī i ka hana, a piʻi koke ka viscosity. ʻO ka hope loa, lilo ia i jelly hiki ʻole ke hoʻololi ʻia. 100 lina kūpono, Hydroxyl polyurethane (helu Polyurethane ma kahi o 20%), RE mahele lāʻau 4-7. Chloroprene rubber (Rubber account ma kahi o 20%) , Ko mākou RE hana 4-7.
Waihona:
E ʻoluʻolu e mālama i loko o ka hue i hoʻopaʻa ʻia ma lalo o 23 ℃, hiki ke mālama paʻa ʻia nā huahana no 12 mau mahina. Hoʻomaʻamaʻa loa ia i ka hānai; e hoʻopuka ia i carbon dioxide a me urea insoluble i ka hopena me ka wai. Inā kū i ka ea teh a i ʻole ka malamalama, e hoʻonui ia i nā loli kala, akā ʻaʻole e hoʻopili ʻia ka hana kūpono.
