Taupānga Hua:
1.Ko te Ethanol he whakarewa pararopi nui, e whakamahia nuitia ana i roto i te rongoa, te peita, nga hua parukore, nga mea whakapaipai, te hinu me te hinu me etahi atu tikanga, e tata ana ki te 50% o te katoa o te kai o te waihano.Ko te Ethanol he rauemi matū tino nui, e whakamahia ana ki te hanga acetaldehyde, ethylene diene, ethylamine, ethyl acetate, waikawa acetic, chloroethane, me etahi atu, ka puta mai i te maha o nga takawaenga o nga rongoa, tae, peita, mea kakara, rapa waihanga, horoi. , pesticides, me etahi atu, neke atu i te 300 momo hua, engari inaianei kei te heke haere te whakamahinga o te ethanol hei takawaenga hua matū, me te maha o nga hua, penei i te acetaldehyde, te acetic acid, te ethyl alcohol, kua kore e whakamahi i te ethanol hei rauemi mata, engari te waipiro ethyl hei rauemi mata.Heoi, kei te heke haere te whakamahinga o te waiwaro hei takawaenga matū, a, he maha nga hua penei i te acetaldehyde, te acetic acid, te ethyl alcohol kua kore e whakamahi i te ethanol hei rauemi mata, engari ka whakakapihia e etahi atu rawa.Ka whakamahia ano te waihano kua oti te para ki te hanga inu.He rite ki te methanol, ka taea te whakamahi i te waihano hei puna hiko.Kua timata etahi whenua ki te whakamahi i te waihano anake hei hinu mo te waka, kua hanumi ranei ki te penehīni (10% neke atu ranei) hei whakaora penehīni.
2.I whakamahia hei whakarewa mo te whakapiri, te peita nitro, te waituhi, te whakapaipai, te waituhi, te peita peita, me etahi atu, me te mea ano he rauemi mata mo te hanga pesticides, rongoa, rapa, kirihou, muka waihanga, horoi, aha atu. , me te rite ki te antifreeze, te wahie, te waipatu me etahi atu.I roto i te ahumahi microelectronics, e whakamahia ana hei kaihoroi me te whakakore, ka taea te whakamahi i te taha o te kaitautoko.
3.I whakamahia hei reagent tātari, penei i te whakarewa.Ka whakamahia ano hoki i roto i te umanga rongoa.
4.I whakamahia i roto i te ahumahi hiko, i whakamahia hei whakakore i te wai me te whakakore i nga kai me te whakakore i nga kai.
5.Used ki te tareka etahi tāpiritanga pararopi electroplating insoluble, whakamahia hoki rite hexavalent chromium whakaiti kaihoko i roto i te matū tātari.
6.I whakamahia i roto i te ahumahi waina, te whakahiato pararopi, te whakakorenga me te whakarewa.
Nga Tuhipoka Rokiroki Hua:
1. Rokiroki i roto i te whare putunga hauhautanga, whai hau.
2.Kia matara atu i te ahi me te puna wera.
3.Ko te pāmahana rokiroki kaua e neke ake i te 37°C.
4. Kia hiritia te ipu.
5.Me penapena motuhake mai i nga oxidants, waikawa, konganuku alkali, amine, me etahi atu, kaua e uru ki te rokiroki.
6.Use rama pahū-tohu me whakaurunga ventilation.
7. Ka aukati i te whakamahi i nga taputapu miihini me nga taputapu ngawari ki te whakaputa korakora.
8.Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere leakage me nga taonga whakaruru tika.
