He iti noa te rerekētanga o te waeine EO, he aha i tino rerekē ai te mahi a te hanganga? — Te mārama ki te kōwhiringa o te Amine Ether ngako me Qixuan TA05

I ngā hui whiriwhiri i ngā matū horoi, ka puta he wero noa: e rua ngā momo ethers polyoxyethylene amine momona, he iti noa te rerekētanga o ngā waeine ethylene oxide (EO) me ngā utu rite, ka taea te whakaputa i ngā hua tino rerekē ina whakauruhia ki roto i ngā hanganga mahi. Ka kitea te rerekētanga o te pumau o te emulsion, te matotoru o te pūnaha, tae atu ki te tae o te hua kua oti. I te mahi ki ngā kiritaki puta noa i te horoi, te mara hinu, te emulsification ahuwhenua, te uku, te tukatuka kohuke me ētahi atu rāngai, ka pātaihia pinepinetia te rōpū hangarau o Shanghai Qixuan Chemical Technology Co., Ltd. ki tētahi pātai matua: me pēhea te whiriwhiri i te tau EO tika?

TA05, arā, ko te tallow amine polyoxyethylene (5) ether, e tuku ana i tētahi otinga māngai mō tēnei pātai. Kāore e whai i te mahi tino nui i runga i tētahi tohu kotahi, engari ka kitea tōna tūranga pono i roto i te whānuitanga o ngā pūnaha tono kanorau.

Ka hangaia te TA05 mā te ethoxylation o te amine tallow tūturu me ngā waeine EO e 5, CAS Nama 61791-26-2. Ko tōna wāhanga hydrophobic he mea whakauru i ngā mekameka alkyl C16–C18 roa, ko te wāhanga hydrophilic he mea whakauru tahi e ngā waeine EO e rima me tētahi rōpū amine protonatable.

Mā tēnei hanganga ahurei ka whakawhiwhia ki a ia ngā āhuatanga mahi takirua. I raro i ngā āhuatanga kūpapa, ka mahi hei matū horoi kore-ionic, e whakatutuki ana i te emulsification me te marara mā te whakamakuku o ngā mekameka EO. I roto i ngā taiao waikawa, ka whakaporotinatia te rōpū amine, ā, ka mau i ngā utu pai, e whakaatu ana i ngā āhuatanga matū horoi cationic me te kaha o te adsorption ki ngā papa kua utua kinotia tae atu ki ngā mata whakarewa, ngā kohuke, ngā muka me ngā matūriki uku. Mā tēnei tikanga mahi takirua i roto i te ngota kotahi e whakatakoto te take matua e whakamahia tonutia ai a TA05 puta noa i ngā ahumahi maha.

Mō ngā āhuatanga ā-tinana, ka puta te TA05 hei wai matotoru mai i te kōwhai mā ki te parauri i te 25°C. He kawakore tōna wairewa 1% me te pH mai i te 9 ki te 11. Ko te uara amine katoa e whakahaerehia ana i waenga i te 110–120 mgKOH/g, te makuku ≤1.0%, te tae Gardner ≤10, ā, ko te uara HLB tata ki te 9. Kei te rohe tonu tēnei HLB i waenga i te hydrophilicity me te lipophilicity, e āhei ai te wairewa pai i roto i ngā āhua hinu i te wā e heke ana ki ngā hononga hinu-wai. Nō reira, he pai mō te emulsification W/O, te co-emulsification me te makuku interfacial, kaua ki te mahi hei emulsifier hinu-i-roto-i-te-wai noa iho.

Ka taea te whakaetoxylate i tētahi rauemi amine matotoru kotahi ki ngā taumata raupapa me ngā wae EO e 2, 5, 10, 15, ka puta he āhuatanga rerekē haere. Mā te iti o ngā tau EO ka kaha ake te lipophilicity, ka nui ake te uara amine me te ngoikore o te wairewatanga wai; mā te nui ake o ngā ihirangi EO ka pai ake te wairewatanga wai, ka neke ake te hiahia ki te emulsifying ki ngā pūnaha O/W.

He tino wairewa te karaehe EO 2 ki te hinu, e hiahia ana kia whakaranua te whakarewa, kia whakamahanatia rānei hei whakamarara i roto i ngā whakatakotoranga maha. Ko ngā karaehe me te 10, neke atu rānei ngā wae EO e whakaatu ana i te wairewatanga wai pai ake, engari he ngoikore te hononga ā-mata i roto i ngā pūnaha hinu nui, totoka nui. E rima ngā wae EO e tutuki ana i te ara waenga taurite: e pupuri ana i ngā wāhanga lipophilic rawaka hei punga ki runga i te hinu, te uku me ngā mata kohuke, i te wā e mau ana te kaha hydrophilic taketake mō te horapa i roto i ngā pāpāho wai. Mō ngā tono e hiahia ana kia rua te emulsification me te adsorption, te whakataurite i te lipophilicity me te mararatanga wai, he maha ngā wā ka eke ake tēnei karaehe i ngā karaehe i ngā pito e rua o te whānuitanga EO.

Koia anō te take e kiia whānuitia ai a TA05 hei "hononga whakatakotoranga". Ka taea te whakarite i tōna wairewatanga wai me tōna pūwāhi kapua mā te whakaranu ki ngā momo EO teitei ake, ā, ka taea te whakanui ake i te mahi lipophilic mā te whakakotahi ki ngā momo EO iti. I roto i ngā pūnaha matū, ka mahi hei poraka hanga ngāwari mō te whakatikatika whakatakotoranga, he maha ngā wā he nui ake te uara hei wāhanga tahi i te kaihoko tuatahi takitahi.

Haunga ngā rāngai o runga ake nei, ka taea te whakamahi hei tāpiri ārai-pūmau me te whakangawari i roto i te tukatuka kakahu mā te mimiti ki runga i ngā mata muka mā roto i ngā rōpū amine kua whakapūmautia. I roto i te whakapūmautanga kohuke, ka mahi hei kaikohi tāpiri, hei kaiwhakamarara rānei, e whakawhirinaki ana ki te mimiti cationic aronga ki runga i ngā mata kohuke.

Mō ngā amine ethoxylates momona, ko te tutuki i ngā paepae whakaritenga te whakaritenga whakauru anake. Ko te mea e whakahaere ana i te pumau o te hanganga mō ngā kiritaki whakamutunga ko te tohatoha EO whaiti, te ihirangi PEG kore utu me te EO kore utu e whakahaeretia ana, me te tae pumau i roto i te rokiroki. Mā te tohatoha EO whānui ka hua ake he kaha emulsifying me te wairewa wai ahakoa he ōrite ngā uara amine. Ko ngā hanganga kua arotauhia i te tauine taiwhanga ka rahua i te wā whakamātautau, i te tauine whakaputa katoa rānei.

I Qixuan, ko ngā tohu whakahaere matua mō TA05 e kapi ana i te uara amine, te makuku, te pH me te tae, me te whakamātautau puranga katoa me te pupuri tauira kia taea ai te whai. Ko te takai paerewa he 180 kg ia pahu, ko te putea IBC me te takai OEM ritenga e wātea ana ina tonoa.

• [1] Tautuhia te matapihi pH i mua i te aromatawai hototahi:He rite te mahi a TA05 ki te cationic i raro i ngā āhuatanga waikawa, ā, he rite hoki ki te non-ionic i raro i ngā āhuatanga kawakore. He rerekē rawa ngā hoa hototahi, te raupapatanga whāngai me te horopeta kua tūtohutia i waenga i ēnei taiao e rua.
• [2] Āta karohia te whakaranu tika ki ngā matū horoi anionic:Ina hangaia ngātahitia me ngā momo anionic, ka tūtohutia kia whakamahia ngā matū takawaenga kore-ionic, ngā raupapatanga whāngai motuhake rānei hei ārai i te kukū tiketike ā-rohe me te hanganga o ngā matūriki.
• [3] Whakahaere pāmahana whāngai:He tino matotoru te TA05, inā koa i raro i ngā āhuatanga hotoke iti te pāmahana. Mā te whakamahana ki te 60°C i mua i te horopeta ka māmā ake te ine tika, ā, ka ārai i te whakapūtanga ā-rohe kāore i te ōrite.

Ko te kōwhiringa o te matū horoi (surfactant) ko te kimi i te pūwāhi tino pai i runga i te pihi whakahāngai EO tonu. Ko te painga o TA05 ehara i te mea kei roto i te mahi tino pai i runga i te āhuatanga kotahi, engari kei roto i taua rohe waenga e warewarehia ana, e whakataurite ana i te lipophilicity me te hydrophilicity me ngā tono nui o te mākete.

E whakarato ana a Shanghai Qixuan Chemical Technology Co., Ltd. i tētahi raupapa katoa o ngā momo tallow amine polyoxyethylene ether. Kei te rite mātou ki te whakarato i ngā momo EO kua whakaritea me te tautoko hangarau tono ngaio e rite ana ki ō whakaritenga whakatakotoranga motuhake.
