Talosaga o Mea:
1. Ethanol o se solvent organic taua, faʻaaogaina lautele i vailaʻau, vali, mea mama, mea teuteu, suauu ma gaʻo ma isi metotia, faʻamaumauga mo le 50% o le aofaʻi o le faʻaaogaina o le ethanol. O le ethanol o se mea fa'ameamea taua, fa'aaogaina i le gaosiga o le acetaldehyde, ethylene diene, ethylamine, ethyl acetate, acetic acid, chloroethane, ma isi, ma e maua mai i le tele o vaila'au, vali, vali, mea manogi, pa'u synthetic, detergents. , vailaʻau faʻamaʻi, ma isi, faʻatasi ma le sili atu ma le 300 ituaiga o oloa, ae o le taimi nei o le faʻaaogaina o le ethanol e avea o se vailaʻau vailaʻau faʻasolosolo ua faʻaitiitia, ma o le tele o oloa, e pei o le acetaldehyde, acetic acid, ethyl alcohol, ua le toe faʻaogaina le ethanol e avea o se mea mata, ae o le ethyl alcohol o se mea mata. Ae ui i lea, o le faʻaaogaina o le ethanol e fai ma vailaʻau faʻasolosolo ua faasolosolo malie ona faʻaitiitia, ma o le tele o oloa e pei o le acetaldehyde, acetic acid, ethyl alcohol ua le toe faʻaaogaina le ethanol e fai ma mea mata, ae ua suia i isi mea mata. O lo'o fa'aogaina fo'i le ethanol fa'apitoa i le gaosiga o meainu. E tutusa ma le methanol, e mafai ona fa'aogaina le ethanol e fai ma puna o le malosi. O nisi atunuu ua amata ona faaaoga na o le ethanol e fai ma suauu ta'avale pe fa'afefiloi i le penisini (10% pe sili atu) e sefe ai le penisini.
2. Faʻaaogaina e avea o se solvent mo faʻapipiʻi, nitro spray paints, varnishes, cosmetics, inks, paint strippers, ma isi, faʻapea foʻi ma se mea mataʻutia mo le gaosiga o vailaau faʻasaina, vailaʻau, paʻu, palasitika, fibre synthetic, detergents, ma isi. , ma pei o le anti'aisa, suauu, fa'ama'i ma isi. I totonu o le microelectronics alamanuia, faʻaaogaina e avea o se faʻamaʻi ma faʻamalo, e mafai ona faʻaogaina faʻatasi ma le faʻamalo.
3. Faʻaaogaina e fai ma suʻesuʻega suʻesuʻe, e pei o le solvent. Faʻaaogaina foi i fale gaosi oloa.
4. Faʻaaogaina i pisinisi faʻaeletoroni, faʻaaogaina e pei o le dewatering ma le decontamination agent ma le degreasing agent mea.
5. Faʻaaogaina e faʻamavae ai nisi mea faʻapipiʻi faʻapipiʻi eletise eletise, faʻaaogaina foi e avea ma sui faʻaitiitia chromium hexavalent i kemisi suʻesuʻe.
6.Used i le uaina alamanuia, organic synthesis, disinfection ma avea o se solvent.
Oloa Teuina Faamatalaga:
1. Teu i totonu ose faleteuoloa malulu, fa'aalili.
2. Taofi ese mai le afi ma le vevela.
3. E le tatau ona sili atu i le 37°C le vevela o le teuina.
4. Faamaufaailoga le koneteina.
5.E tatau ona teuina eseese mai oxidants, acids, alkali metals, amines, ma isi, aua le faʻafefiloi le teuina.
6. Fa'aaogā moli fa'amalama ma mea e fa'afefe ai le pa.
7. Faʻasaina le faʻaogaina o masini masini ma mea faigaluega e faigofie ona gaosia ai aloiafi.
8.O le nofoaga e teu ai e tatau ona faʻapipiʻiina i le leakage faʻalavelave faʻafuaseʻi meafaigaluega togafitiga ma mea talafeagai malutaga.
