Polyethyleneimine (PEI) Cas 9002-98-6He whānuitia ngā whakamahinga i roto i te umanga kakahu, ā, he rauemi pūmua mahi nui. Ko tōna uara matua kei roto i te nui o ngā kationa utu pai me te kaha tauhohenga teitei, e āhei ai te whakakotahi me ngā muka utu kino, ngā tae, me ngā momo tauhohenga mahi, ā, nā reira ka whakawhiwhia ki ngā kakahu he āhuatanga hou, he āhuatanga whakarei ake rānei.
Ko ngā tono me ngā uara matua e whai ake neiPEIi roto i te umanga kakahu:
Ⅰ. Te Tae me te Tā: Te Whakapai Ake i te Mahi Tae me te Ataahua ki te Taiao
PEIka whakapai ake i ngā pānga tae me te tā o ngā kakahu mā te herea i ōna wāhanga tae cationic me anionic, me te whakaiti i te parahanga.
1. Te Whakanuia o te Hōhonutanga Tae (Uara K/S) me te Pumautanga Tae:
Ko ngā papanga kua tukatukahia ki te PEI pērā i te miro me te huruhuru hipi he nui ake te mimiti o te tae, ka hua ake he tae hohonu ake, he tae kanapa ake. I te wā kotahi, ka tino pai ake ngā āhuatanga pumau o ngā papanga kua taehia me ngā papanga kua tāia (pērā i te ātete ki te horoi me te ātete ki te mirimiri). Hei tauira, i whakaatuhia e tētahi rangahau i te tau 2025 he pikinga ōrau nui o te kaha o te tae (uara K/S) o ngā papanga kua tukatukahia ki te PEI.
2. Te Whakatutuki i te Tānga Waituhi Kore-Maimoatanga/Kore-Horoi:
Te whakamahi i te peka nuipolyethyleneimine (PEI)Mō ngā waituhi tae kua whakarerekētia (pēnei i te waituhi PEI-R218), ka taea te tā tika mā te waituhi waituhi ki runga i ngā papanga kāore i rongoatia, ka eke ki te tere piri tae neke atu i te 98.7%. Mā tēnei ka whakakorehia ngā tukanga horoi rahi i mua i te tānga me muri i te tānga, ka tino whakaitihia te whakapaunga o ngā matū, te wai, me te pūngao.
3. Te whakatairanga i te whakamahinga o ngā tae taiao:
Ka taea e ngā papanga hiraka kua whakarerekētia e PEI te whakapai ake i te tere tae me te pānga tae o ngā tae taiao pēnei i te curcumin, e whakatairanga ana i ngā tukanga tae e pai ake ana ki te taiao.
II. Te whakaotinga mahi: Te hoatu i ngā "mana nui" ki ngā kakahu
PEIhe tāpiri matua i roto i te hanga kakahu whai hua, he tino pai ki te ātete mura.
1. Te ātete mura teitei-pai
He nui te hauota,PEIe whakamahia ana hei pūtake waro, hei pūtake hau rānei i roto i ngā pūnaha aukati mura intumescent, e mahi tahi ana me ētahi atu aukati mura kei roto he phosphorus me he silicon.
Ngā papanga miro: Ina honoa ki ngā mea ārai mura e ahu mai ana i te koiora pērā i te waikawa phytic (PA), mā te whakawhiti katote, te tāpiri rānei ki ngā mea honohono, ka taea te hanga paninga ārai mura tino whai hua.
2. Ngā papanga viscose
Hei ārai mura, ka taea e te Phosphate-esterified PEI te whakanui ake i te taupū hāora whakawhāiti (LOI) o ngā kakahu ki te 28.9%, ka tutuki ai te tineia-ā-unoa ina tangohia te mura.
3. PA56, PAN, me ētahi atu muka hangai
Mā te hangarau honohono, mā te hangarau whakakotahi-ā-paparanga rānei, ka taea te hanga whatunga honohono, ka tutuki ai te ātete mura roa. Hei tauira, ko te papanga PAN i rongoatia ki te PA/PEI/APTES e whakaatu ana i te pikinga o te taupū hāora whakawhāiti (LOI) mai i te 17.4% ki te 27.5%, ā, he tino pai ngā āhuatanga pehi paowa.
4. Ngā āhuatanga ārai huakita me te ārai mate
He āhuatanga patu huakita kei roto i te PEI me ōna matū honohono whakarewa (pērā i te PEI-Cu). Ko ngā papanga miro i rongoatia ki te PEI i whakaatu i te 83.33% te auau patu huakita me te 74.2% ngā āhuatanga ārai mate i roto i ngā tono triboelectric nanogenerator (T-TENG).
5. Te Whakarei Ahu me ngā Āhuatanga Ārai-Patū:
Parenga Hikohiko: Ka whakakaha ake te miro polyamide (PA) kua whakarerekētia e PEI i te piri o te paninga graphene oxide (GO). Ka mau tonu te kawe hiko teitei o te miro kawe hiko hua o te 4.7 × 10³ S/m i muri i te 10,000 piko, ka tutuki ai te whai huatanga parenga hikohiko tae atu ki te 66.7 dB.
6. Ngā Āhuatanga Ārai-Patū
PEIka whakanui ake i te wai-aro o ngā kakahu, ka whakaiti i te hanga hiko pateko.
7. Te Whakakore-huruhuru
He tukanga whakaoti ārai-whakapiripiri tonu mā te whakamahi i te pāhare pākawa waro (PMS)-PEI i roto i tētahi tukanga e rua-taahiraa. Kāore he hauwaiora, he tukanga pai hoki mō te taiao.
8. Te Whakapai Ake i te Makuku me te Wai-whakapaipai
PEIMā te maimoatanga ka tino whakapai ake i te mākū o ngā muka wai-arohaiti pērā i te huruhuru hipi, ā, ka pai ake ngā hua o te PEI taumaha-ngota teitei ake.
III. Te whakarerekētanga o te mata: Te hanga i tētahi "piriti" whai hua
PEIka taea te whakamahi hei "paparanga piriti" hei "kaihoko punga" rānei mō te whakarerekētanga muka hōhonu.
1. Te Whakapai Ake i te Kaha o te Paninga
Hei paninga turanga, ka taea e te PEI te whakapai ake i te kaha o te uta me te here o ngā rauemi mahi (pērā i te MXene (Ti₃C₂Tₓ) me te graphene oxide (GO)) i runga i te mata muka.
2. Te Whakarite i ngā Pūhui Mahi
Ka taea te whakamahi hei whakarite i ngā mea hiato pēnei i ngā aerogels PEI@PLA mō ngā tono pēnei i te mimiti tae.
3. Whakatakotoranga Matū Whakakorikori
Hei kaihopu cationizing, ka taea te whakamahi hei rongoā i ngā muka miro, kia taea ai te whakakikorua matū catalytic o te parahi sulfide (CuS) ki runga i tōna mata, kia tutuki ai te kawe hiko.
Whakarāpopototanga
Polyethyleneimine (PEI)He mea nui tēnei i roto i te umanga kakahu puta noa i ngā wāhanga katoa, mai i te tae me te whakaoti mahi ki te whakarite i ngā rauemi hiato mahi-teitei. Ehara i te mea he "whakatairanga" noa iho hei whakapai ake i te mahi me te atawhai taiao o ngā kakahu tuku iho (miro, huruhuru hipi, hiraka), engari he rauemi matua anō hoki mō te whakawhanake i ngā kakahu hou, atamai, tiaki, me te mahi-teitei.
Me mōhio ko te pānga o te tono oPEIe pā tata ana ki ōna tawhā hanganga pērā i te taumaha ngota me te taumata o te peka. I roto i ngā tono mahi, me tīpako me te arotau kia rite ki te tukanga motuhake.
