I-Polyethyleneimine CAS 9002-98-6 ene-NW 600-20000000
I-Polyethyleneimine (efushaniswe ngokuthi i-PEI) iwuketshezi olungenambala noma oluphuzi olunobuthi obukhulu. Inombolo ye-CAS 9002-98-6. Incibilika emanzini, i-ethanol, i-hygroscopic, ayincibiliki ku-benzene kanye ne-acetone. Ukuna kwemvula kuzokwenzeka lapho isixazululo se-polyethyleneimine sihlangana ne-sulfuric acid enenani le-pH elingaphansi kuka-2.4. Isixazululo samanzi sishajwa kahle, futhi ukungezwa kwe-formaldehyde kukhiqiza ukujiya. I-Polyethyleneimine PEI isetshenziswa njenge-ejenti yamandla emanzi yephepha lokuphefumula elingalingani, futhi i-ejenti yokugcina kanye ne-ejenti yokushaya enkambisweni yokwenza iphepha kunganciphisa izinga lokushaya kwe-pulp. Thuthukisa amandla okususa amanzi ephepha. Ukoma kwephepha kukhushulwa ngo-1% - 4%. Amandla okukhiqiza akhushulwa ngo-5% - 20%.

1. I-Polyethyleneimine PEI esetshenziswa njenge-ejenti enamandla emanzi yephepha elingaphefumuli ngobukhulu, i-ejenti yokugcina kanye ne-ejenti yokushaya enkambisweni yokwenza iphepha, i-PEI inganciphisa izinga lokushaya kwe-pulp. Thuthukisa amandla okususa amanzi ephepha. Ukoma kwephepha kukhushulwa ngo-1% - 4%. Amandla okukhiqiza akhushulwa ngo-5% - 20%.
2. Isixazululo se-polyethyleneimine sisetshenziswa kabanzi emikhakheni yokunyathelisa i-inki, ukumboza, ukunamathela njalo njalo.
3. I-PEI esetshenziswa ekwenzeni amaphepha ekwelapheni amanzi, isixazululo se-electroplating kanye ne-dispersant.
4. I-Polyethyleneimine esetshenziswa njenge-epoxy resin reagent, i-aldehyde adsorbent kanye ne-dye fixative.
1. Okuvelele Kohlelo Lokusebenza
Ukwenziwa Kwephepha Ukuhlanzwa Kwamanzi Amhlophe: Kuthatha indawo kasawoti we-aluminium wendabuko, kuthuthukisa ukucaca kwamanzi, futhi kunciphisa i-COD.
Ukwelashwa Kwamanzi Angcolile Nge-Electroplating: Kubamba i-Cu²⁺, i-Ni²⁺, kanye ne-Cr⁶⁺ ngesikhathi esisodwa, okuqinisekisa ukuthi ukukhishwa kwamanzi kuyahlangabezana nezindinganiso.
Amanzi Angcolile Adayiwe: Izinga lokushintsha umbala libe ngaphezulu kuka-95%, kunciphisa izindleko zokusebenza ngo-30%.
2. I-PEI inikeza ububanzi obukhulu besisindo sama-molecule angu-500–750,000 futhi ingafakwa i-acetylated, i-carboxylated, i-PEGylated, futhi ilebula nge-fluorescent ukuze kufezwe ukwakheka kokuncibilika kwamanzi, ukuncibilika kwamafutha, kanye nokuqondiswa lapho kudingeka.
3. Iqhathaniswa ne-BASF, i-Catalyst kanye neminye imikhiqizo. Imininingwane efanayo inamanani ancintisana kakhulu.
4. Nikeza ulwazi lobuchwepheshe lomuntu ngamunye. Faka imininingwane ethile ngokwezinhlelo zokusebenza zomkhiqizo wamakhasimende.
