Ngā āhuatanga ā-tinana me te matū
Ethylene glycol tertiary butyl ether (ETB): He matū matū pararopi, wai kore tae me te maramara muramura me te hā o te mint. Wairewa i roto i te nuinga whakarewa organic, ka tareka ia amino, nitro, alkyd, kiriaku me etahi atu resins. I te pāmahana rūma (25 ° C), ka taea te whakauru ki te wai, he iti te paitini, he iti te riri. Na tona ahuatanga motuhake o te hydrophilic me te kaha ki te whakakore i te whakakotahitanga, na te mea he whanui te whanaketanga i roto i te waahi o nga paninga tiaki taiao me te kaha hou.

Whakamahinga:Ethylene glycol tertiary butyl ether, te tino rereke ki te ethylene glycol butyl ether, he rerekee, he iti rawa te kakara, he iti te paitini, he iti te hohenga whakaahua matū, me etahi atu, he ngawari ki te mamae kiri, me te hototahitanga wai, te taherapa peita marara te pumau He pai te hototahi ki te te nuinga o nga kapia me nga whakarewa pararopi, me te pai o te hydrophilicity. Ka taea te whakamahi whanui i roto i te maha o nga mara penei i te paninga, te mangumangu, te horoi horoi, te muka makuku, te plasticizer, te takawaenga whakahiato waro me te tango peita. Ko ona whakamahinga matua e whai ake nei:
1. Awhakarewa paninga queous: matua mo nga punaha wai whakarewa, peera ahumahi peita taherapa wai. Na te mea ko te uara HLB o te ETB he tata ki te 9.0, ko tana mahi i roto i te punaha whakamararatanga he mahi hei dispersant, emulsifier, rheological agent and cosolvent. He pai te mahi mo te peita taherapa, te paninga marara colloidal me te whakakore i te paninga kapia wai i roto i nga paninga wai. , Mo te peita o roto me waho i roto i nga whare, te tuatahi o nga motuka, te peera tae me etahi atu mara.
2. Pkaore he whakarewa
2.1Hei whakamarara. Ko te hanga o te peita kiriaku pango pango me te pango motuhake, te peita kiriaku te tikanga me nui te wa ki te huri i te waro waro pango ki te whakatutuki i tetahi tino pai, me te whakamahi i te ETB kua whakamakukuhia te waro waro pango, ka taea te whakaiti i te wa huri. neke atu i te haurua, a, i muri i te whakaoti Ko te ahua o te peita he maeneene me te maeneene.
2.2Ka rite ki te kaiwhakatairitenga kaihoko defoamers, whakapai ake i te wai marara peita tere whakamaroke, maeneene, kanapa, adhesion nohopuku. Na tona hanganga tert-butyl, he nui te pumau o te whakaahua matū me te haumaru, ka taea te whakakore i nga pene kiriata peita, nga matūriki iti me nga mirumiru. Ko nga whakakikorua wai i hangaia me te ETB he pai te pupuri, ina koa i raro i te iti o te pāmahana i te takurua.
2.3Whakapai ake te kanapa. ETB whakamahia i roto i te peita amino, peita nitro, ki te aukati i te hanga o "kiri karaka" -rite tohu, peita kiriata mōhinuhinu piki 2% ki te 6%.
3. Ink mararaKo te ETB i whakamahia hei whakarewa waituhi i hangaia, hei whakamararatanga waimeha ranei e whakamahia ana i roto i nga waituhi ta, ka taea e koe te whakapai ake i te rheology waituhi, te whakapai ake i te kounga o te tere tere me te kanapa, te piri.
4. Fkaihoko tango iberUS Alied-Signal Company ki te 76% o te hinu kohuke kei roto nga muka polyethylene me te tangohanga ETB, i muri i te tangohanga o te hinu kohuke ka heke 0.15%.
5. Waikano phthalocyanine Titanium DioxideKo te kamupene Japanese Canon ki Ti (OBu) 4-amino-1,3-isoindoline o te otinga ETB i oho i te 130 ℃ 3h, ka whiwhi 87% parakore titanium Phthalocyanine tae. A ko te tioata oxytitanium phthalocyanine i hangaia mai i te porous titanium oxide phthalocyanine me te ETB ka taea te whakamahi hei whakaahua whakaahua whakaahua e tino aro ana ki te rama roa-roa.
6. Kaihoroi whare paiI tukinotia a Asahi Denko ki te propylene oxide me te hua tauhohenga kei roto KOH ETB ka whiwhi i te poly propylene oxide mono-t-butyl ether, he mea pai, he pai te horoi whare.
7. Te peita anti-corrosion hauwaiNippon Paint Company me te diethyl ether, te kapia kiriaku, ETB, butanol, TiO2, cyclohexyl ammonium carbonate, he maatete aukati pahuka ki te whakarite i te peita waikura waikore ka rehu.
8. waro kiriata parenga o nga waahanga reo irirangime te ETB hei parenga waro waro kiriata parenga, he maeneene te mata, ka taea te whakakore i te kohao me te whakaraerae o nga ahuatanga kino me te whakapai ake i nga mahi o nga waahanga hiko.
9. Tautoko wahie
Ka taea te whakamahi i te ETB hei whakarewa tahi me te whakarereke i roto i nga kora hou, ehara i te mea ko te whakapai ake i te pai o te wera, engari ano hoki te whakaiti i nga tukunga, hei puna kaha hou mo nga kohua me nga miihini miihini moana nui, kei reira nga whakaritenga pakari o te taiao me nga painga o te tohatoha kaupapa here.
