Ngā Tohu Hua

Whakamahinga:Ko te Dimethylamide (DMF) he rauemi mata matū nui me te whakarewa mahi-teitei, e whakamahia ana i roto i ngā ahumahi pēnei i te polyurethane, te acrylic, ngā rongoā, ngā patupatu, ngā tae, ngā hikohiko, me ētahi atu. Hei horoi me te whakamaroke i roto i te ahumahi polyurethane, e whakamahia ana i roto i te hanga hiako hangai maku; Hei takawaenga rongoā hangai i roto i te ahumahi rongoā, e whakamahia whānuitia ana i roto i te hanga o te doxycycline, cortisone, me ngā rongoā sulfonamide; Hei whakarewa i roto i te ahumahi muka acrylic, e whakamahia ana i roto i te hanga miro maroke o ngā muka acrylic; Whakamahia i roto i te ahumahi patupatu hei hanga i ngā patupatu patupatu patupatu whai hua me te iti te paitini; Whakamahia hei whakarewa tae i roto i te ahumahi tae; Te tinei i ngā wāhanga kēne me te horoi i ngā papa ara iahiko i roto i te ahumahi hikohiko; Ko ētahi atu ahumahi ko ngā kaikawe o ngā hau kino, ngā whakarewa mō te tioata rongoā, ngā piripiri, me ētahi atu.

Ingoa matū: N, N-dimethylacetamide

He whakarewa kaha te Dimethylacetamide, kāore i te porotinitia, ka taea te whakarewa i ngā momo matū, ā, ka taea te whakaranu ki te wai, ki ngā ether, ki ngā ketone, ki ngā ester, me ētahi atu. He tino pumau te pāmahana, he iti te ātete ki te waikura, he iti te waikura, ā, he iti te paitini. He pai te wairewa mō ngā momo kapia, inā koa te kapia polyurethane me te kapia polyimide, ā, ka taea te whakamahi hei whakarewa mō ngā muka hangai ātete-wera, ngā kiriata kirihou, ngā paninga, ngā rongoā, me te miro acrylonitrile. Ko te Dimethylacetamide, he iti te paitini, he teitei te kohua, he teitei te porotini, he whakarewa kore-porotini me te takawaenga matū, e whakamahia whānuitia ana i roto i ngā mara pēnei i ngā rauemi hangai, ngā rongoā, ngā patupatu pepeke, ngā muka matū, te tukatuka hinu, me ngā tae waro.

He aha ngā whakamahinga matua o te dimethyl formamide?

01whakamahia hei matū tātari me te whakarewa mō te kapia ethylene me te acetylene

02He whakarewa rauropi pai rawa atu e whakamahia ana hei whakarewa mō te polyurethane, te polyacrylonitrile, me te polyvinyl chloride, me te mea hoki hei rauemi mata mō ngā tangohanga, ngā rongoā, me ngā patupatu pēnei i te imidacloprid

03Ehara i te mea he rauemi matū whānui te Dimethylformamide, engari he whakarewa pai hoki mō ngā whakamahinga maha. He whakarewa pai te Dimethylformamide mō ngā momo polymer teitei pērā i te polyethylene, te polyvinyl chloride, te polyacrylonitrile, te polyamide, me ētahi atu. Ka taea te whakamahi mō te miro mākū o ngā muka hangai pērā i ngā muka polyacrylonitrile me te hanga polyurethane; Whakamahia mō te hanga kiriata kirihou; Ka taea hoki te whakamahi hei tango peita mō te tango peita; Ka taea hoki e ia te whakarewa i ētahi tae wairewa iti, ka hoatu ki a rātou ngā āhuatanga o ngā tae. Ka whakamahia te Dimethylformamide mō te tango hauwai kakara, me te wehe me te whakaora i te butadiene mai i te wāhanga C4 me te isoprene mai i te wāhanga C5. Ka taea hoki te whakamahi hei matū whai hua mō te wehe i ngā wāhanga kore-hauwai mai i te paraffin. He pai te whiriwhiri mō te wairewa o te waikawa isophthalic me te waikawa terephthalic: he nui ake te wairewa o te waikawa isophthalic i roto i te dimethylformamide i tērā i roto i te waikawa terephthalic. Ka taea e te tango whakarewa, te whakatiotanga wāhanga rānei i roto i te dimethylformamide te wehewehe i ngā mea e rua. I roto i te umanga matū hinu, ka taea te whakamahi i te dimethylformamide hei ngongo hau mō te wehewehe me te whakamahine i ngā hau. I roto i ngā tauhohenga rauropi, ehara i te mea he whakarewa noa te dimethylformamide, engari he takawaenga nui hoki i roto i te hanga rauropi. Ka taea te whakamahi hei whakaputa chlorpyrifos i roto i te umanga patu pepeke; I roto i te umanga rongoā, ka taea te whakamahi hei hanga pyrimidine iodide, doxycycline, cortisone, huaora B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfuracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, me ētahi atu. Ka whai wāhi te Dimethylformamide ki ngā tauhohenga hydrogenation, dehydrogenation, dehydration, me te dehalogenation, ka whakaiti i te pāmahana tauhohenga me te whakapai ake i te parakore o te hua.

04Te matū titration kore-wai, te whakarewa mō te kapia ethylene me te acetylene, te hanga rauropi, te whakaahua, te chromatography hau i te wāhanga tūmau (te pāmahana whakahaere mōrahi 50 ℃, te whakarewa methanol), te wehenga me te tātari i ngā warowaihā C2-C5, me te kaha ki te wehe i te noa, te isobutene, te cis, me te trans butene. Te tātari toenga pesticide. Te hanga rauropi. Te hanga peptide. Whakamahia i roto i te umanga whakaahua.
