Kore tae mārama 99.5% wai Ethyl Acetate mō te tohu ahumahi
Whakamahinga
He whakarewa ahumahi pai rawa atu te Ethyl acetate, ā, ka taea te whakamahi i roto i te muka nitrate, te muka ethyl, te rapa chlorinated me te vinyl resin, te cellulose acetate, te cellulose butyl acetate me te rapa hangai, tae atu ki ngā waituhi muka nitro wai mō ngā mīhini tārua. Ka taea te whakamahi hei whakarewa piri, hei whakarewa peita. Ka whakamahia hei matū tātari, hei matū paerewa me te whakarewa mō te tātari chromatography. I roto i te umanga kakahu ka taea te whakamahi hei kaihoko horoi, i roto i te umanga kai ka taea te whakamahi hei kaihoko tango kakara waipiro whakarerekē motuhake, engari ka whakamahia hoki hei tukanga rongoā me te kaihoko tango waikawa waro. Ka whakamahia hoki te Ethyl acetate ki te hanga tae, rongoā me ngā mea kakara.
Me rongoa i te pāmahana rūma, ā, me pupuri kia maroke, kia hauhautanga hoki, kia kore ai e pāngia e te rā me te haumākū. Ka taea te poke i te ethyl acetate e ngā mea mura, ngā waikura, ngā waikawa kaha me ngā kawakore, nō reira me wehe atu i ēnei matū ina rongoatia, ina whakamahia hoki hei karo i ngā tūponotanga.
Ngā horopaki tono
He whānuitia ngā whakamahinga o te ethyl acetate. Ko ētahi o ngā wāhi whakaputa me ngā whakamahinga nui ko:
1. Te whakaputa i ngā wāhanga pēnei i te whakapaipai, te tiaki whaiaro me ngā hinu kakara.
2. Te hanga tae, kapia, paninga me ngā waituhi, hei whakarewa.
3. I roto i te umanga rongoā, ka taea te whakamahi hei whakarewa me te tango.
4. He whānuitia te whakamahinga i roto i te umanga kai me te inu, i roto i te pia, te waina, ngā inu, ngā mea kakara, ngā wai hua me ētahi atu mara hei kaihoko kakara.
5. He maha ngā wā e whakamahia ana hei whakarewa i roto i ngā taiwhanga me ngā mahi hanga.
