Ngā āhuatanga matū
He wai hinuhinu kore tae me te kakara o te amine.Ka taea te whakauru ki te wai, te waipiro, te etera, te ester, te ketone, te hauwai hauhau, te hauwai kakara.
tirohanga whānui
N-methyl pyrrolidinone mō te tātai rāpoi poto: C5H9NO, Ingarihi: 1-methyl-2-PyrrolidinOne, he kore tae te ahua ki te kowhai marama te wai maramara, me te haunga haukini iti, ka uru ki te wai ahakoa te rahi, ka whakarewahia ki te etera, acetone me hākawa, hauwai hauhā, hauwai kakara me etahi atu whakarewa pararopi, Tata rawa te konatunatua ki nga whakarewa katoa Puka matū, ira koropuputanga 204 ℃, ira flash 91 ℃, hygroscopic, āhuatanga matū pūmau, kahore he waikura ki te waro maitai, konumohe, paku waikura ki te parahi.Kei a ia nga painga o te iti pokey, pai matū me te waiariki pūmautanga, teitei polarity, iti pähekeheke, miscibility mure ore ki te wai me te maha whakarewa organic, me ētahi atu Ko tenei hua he tarukino moroiti, te kukū rohe whakaaetia i roto i te rangi ko 100PP.
Nga whakamahinga matua
(1.) Koeke Ahumahi:
Te whakahinu hinu para, te hinu whakahinuhinu antifreeze kaihoko, syngas desulfurization, rauemi whakamatao hiko, otaota ahuwhenua, taapiri pesticide, whakaora hau hiku PVC, paninga teitei, mangumangu, hanga whakangao o nga taapiri me nga marara.Hei tauira, whakamahia ki te tango i nga mea kakara i roto i te hinu whakahinuhinu ki te whakatutuki i te kaupapa o te para o te hinu whakahinuhinu;Na te nui ake o te whakarewatanga o te kapia NMP, hei whakarewa mo te tukatuka kapia ka taea te whakamahi motuhake i roto i te hanga o te paninga, te peita o te papa, te parani, te kiriata whakakikorua hiato, nga taputapu whakauru waea enameled, nga papanga muka me nga taapiri me etahi atu hua.
(2. ) Taumata noa:
Te tangohanga me te whakaora i nga rawa pararopi taketake, penei i te tangohanga acetylene me te butadiene, isoprene, aromatics me etahi atu tangohanga.Ka taea te whakamahi hei whakarewa ki te whakaora i te acetylene mai i te hau maori, te hau naphtha pyrolysis marama ranei.Hei tangohanga mo te wehe me te whakaora i te butadiene tino parakore mai i te pakaru C4 waiwaro, ko te tere whakaora he 97%, a ko te ma o te butadiene kua whakahokia ko 99.7%.Hei tangohanga mo te whakaora i te isoprene tino parakore mai i te pakaru C5 waiwaro, ko te 99%.Na te nui o te whakarewatanga me te iti o te pehanga mamaoa mo nga mea kakara, he iti te terenga mate o te kaihoko tangohanga, he tiketike hoki te tere whakaora o nga mea kakara.
(3.) Reagent taumata:
Ko te ara iahiko whakauru, te kopae pakeke me etahi atu whakaritenga mo te tino whakahaere i nga katote whakarewa me nga matūriki o te ahumahi o te whakaheke, te whakaheke, te atuaxing, te whakakoi, te aukati waikura, te peita, penei i te wai tango photoresist, IC semiconductor ahumahi taputapu pū, LCD wai karaihe rauemi, PCB taia ia iahiko poari, horoi kōpae mārō;I tua atu i te wai kirikiri mahi a te whatukuhu, te wai kirikiri whakamaoritanga o te moana me etahi atu whakarewa i hangaia e te umanga rongoa.
