Nā noi o PACM
Hiki ke hoʻohana ʻia ka EPOXY RESIN CURING AGENT PACM no ka hoʻoponopono ʻana i nā ʻano ʻano like ʻole o ka polyurethane coatings a me nā mea hoʻopili me ka ʻike maikaʻi a me ka pale melemele. ʻO ka epoxy resin i ho'ōlaʻia e EPOXY RESIN CURING AGENT PACM i loaʻa i ka Chemicalbook's maikaʻi wela wela, dielectric properties, solvent resistance, mechanical properties, a me ka maikaʻi o ka optical properties, weather resistance, a hiki ke hoʻohanaʻia i nā mea hoʻoheheʻe, nā mea optical, nā uhi, Engineering plastics, adhesives a me nā māla'ē aʻe.
- ʻO 4,4'-Methylenebis(cyclohexylamine) he mea hiki ke pale i ka shale kiʻekiʻe.
- E hoʻohana ʻia ʻo 4,4'-Diaminodicyclohexyl methane e like me nā mea waena a me nā mea hoʻōla epoxy.
- Hoʻohana ʻia ʻo 4,4'-Diaminodicyclohexylmethane e like me ka epoxy curing agents. He mea koʻikoʻi ia no ka hana ʻana i ka ʻili, nā huahana pāpaʻi, nā plastics, nā kala, a me nā polymers pili kiʻi. Hoʻohana ʻia ia i ka hana ʻana i nā diisocyanates a me nā polyamides. Hoʻohana ʻia ia e like me ka lubricant additive e like me ka corrosion inhibitor.
Hoʻomākaukau: Hoʻololi i ka pauka 1g titanium dioxide i loko o 40ml o ka wai a me ka hui methanol (ka wai i kahi ratio methanol volume o 9: 1), e hoʻoulu maikaʻi ma hope o ka hui like ʻana, e hoʻohui i 60 μmol/ml RUCL3 · XH2O ʻeleʻele ʻeleʻele wai wai e hoʻomalu i ka nui o ka titanium dioxide i ka titanium diWoxide ʻO ka %. Ma hope o 3 mau hola o ka hoʻopaʻa ʻana i ka sila wela o ka lumi a me ka hoʻoulu ʻana no 3 mau hola, e hoʻohui i ka 1m sodium hydroxide solution a hiki i ka PH10.5 e hoʻomau i ka sila a hoʻoulu ʻia no 20 mau hola. Ma hope o ka centrifugation a me ka wai a me ka hui ethanol ua holoiʻia me ka wai a me ka ethanol no 3-5 manawa, 60 ° C. catalyst. Hoʻokomo ʻia nā catalysts hou i hoʻomākaukau ʻia i loko o ka reactor, ua hoʻohui ʻia kekahi leo o nā solvents, a ua hoʻohui ʻia kahi nui kūpono o 4,4'- ʻelua Chemicalbook aminomyl methane (MDA). Ma hope o 10 mau manawa, holoi ʻia ka reactor i pani ʻia me ka ipu hao hydrogen reaction a 150 ° C e hoʻomaka ai i ka hopena. ʻAʻole i emi iho ka lākiō Moore o ka hydrogen a me MDA ma mua o 80, a ʻo ke kaomi hydrogen ʻo 1 a 5MPa, a ua lawe ʻia ka hopena hopena a me ka helu hoʻololi i ka manawa maoli. Hiki i ke apo benzene ma MDA ke lilo koke i hydrogen e hana i hoʻokahi huahana hydrogenation apo benzene (+6H) a me ka hydrogenation o ka hydrogenation o bisopyzhenbenzhenyl. Pono e ʻōlelo ʻia ʻo ka 4,4'-dihydrophill methal methane he hui maka o kahi nylon kūikawā.
