Imikoreshereze ya PACM
EPOXY RESIN CURING AGENT PACM ishobora gukoreshwa mu gutunganya ubwoko butandukanye bw'imyenda ya polyurethane n'amakoride atagira ingaruka ku bidukikije, abonerana neza kandi agakomera umuhondo. Resine ya epoxy ivuwe na EPOXY RESIN CURING AGENT PACM ifite ubushobozi bwo kurwanya ubushyuhe, imiterere ya dielectric, ubushobozi bwo kurwanya solvent, imiterere ya mekanike, ndetse n'imiterere myiza y'amatara, ubushobozi bwo kurwanya ikirere, kandi ishobora gukoreshwa mu bikoresho bigabanya ubushyuhe, ibikoresho by'amatara, amatara, pulasitiki y'ubuhanga, amakoride n'ibindi.
- Methylenebis ya 4,4' (cyclohexylamine) ni umuti ushobora gukumira cyane kandi urwanya ubushyuhe bwinshi.
- Methane ya 4,4'-Diaminodicyclohexyl ikoreshwa nk'ibintu bifasha mu kuvura ibidukikije n'ibintu bitanga uburozi bwa epoxy.
- 4,4'-Diaminodicyclohexylmethane ikoreshwa nk'ibikoresho bivura epoxy. Ni igikoresho gikoreshwa mu gukora uruhu, ibikoresho bya kabutura, plastiki, amarangi, na polymeri zishobora kwitabwaho n'amafoto. Ikoreshwa mu gukora diisocyanates na polyamides. Ikoreshwa kandi nk'inyongeramusaruro z'amavuta nk'uko bikoreshwa mu kugabanya ubushyuhe n'ingufu.
Uburyo bwo gutegura: Shyira garama 1 y'ifu ya titaniyumu dioxide muri 40ml y'amazi n'uruvange rwa methanol (amazi kugeza ku gipimo cy'ingano ya methanol cya 9: 1), kangura neza nyuma yo kuvanga neza, ongeramo 60 μmol/ml RUCL3 · XH2O umuti w'amazi w'umukara wijimye kugira ngo ugenzure ingano ya titaniyumu dioxide muri titaniyumu dioxide. Umutwaro ni 5WT%. Nyuma y'amasaha 3 ufunze, shyiramo umuti wa sodium hydroxide wa 1m kugeza igihe PH10.5 ikomeje gufunga hanyuma uvange amasaha 20. Nyuma yo gukaraba no kuvanga amazi n'uruvange rwa ethanol wogejwe n'amazi na ethanol inshuro 3-5, 60 ° C. catalyst. Catalyst nshya zateguwe zishyirwa muri reactor, hongerwamo ingano runaka y'ibintu bishongesha, hanyuma hongerwamo ingano ikwiye ya 4,4'- Chemicalbook amin aminomyl methane (MDA) ebyiri. Nyuma y'inshuro 10, reactor ifunze yogejwe n'ikigega cya hydrogen reaction kugeza kuri 150 ° C kugira ngo itangire reaction. Igipimo cya Moore cya hydrogen na MDA cyari kitari munsi ya 80, kandi igitutu cya hydrogen cyari hagati ya 1 na 5MPa, kandi umusaruro w'impinduka n'igipimo cyo guhindura byafashwe mu gihe nyacyo. Impeta ya benzene muri MDA ishobora kuba hydrogen vuba kugira ngo ikore umusaruro umwe wa hydrogenation wa benzene (+6H) hamwe na hydrogenation ya hydrogenation ya bisopyzhenbenzhenyl. Ni ngombwa kuvuga ko 4,4'-dihydrophill metal methane ari ikintu kivangwa na nylon yihariye.
