Polyethylenimine (PEI)bụ polymer-soluble mmiri. Ntinye uche na mmiri nke ngwaahịa azụmaahịa na-abụkarị 20% ruo 50%. PEI bụ polymerized site na ethylene imide monomer. Ọ bụ polymer cationic nke na-apụtakarị dị ka mmiri na-enweghị agba na-acha odo odo ma ọ bụ nke siri ike nwere ụdị arọ dị iche iche na ụdị nhazi.

Gịnị bụpolyethyleneimineọrụ?

1. High adhesion, elu absorption amino otu nwere ike meghachi omume na hydroxyl otu na-etolite hydrogen bond, amine otu nwere ike meghachi omume na carboxyl otu na-etolite ionic bond, amine otu nwekwara ike meghachi omume na carbon acyl otu na-etolite covalent bond. N'otu oge ahụ, n'ihi otu polar ya (amine) na hydrophobic group (vinyl), enwere ike ijikọta ya na ihe dị iche iche. Site na ike njikọ ndị a zuru oke, enwere ike iji ya mee ihe n'ọtụtụ ebe n'ọhịa nke akara, ink, agba, ihe nkedo na ihe ndị ọzọ.

2. Akwa-cationic polyvinyl imide dị n'ụdị polycation na mmiri, nke nwere ike imebi na adsorb niile anionic bekee. Ọ na-emekwa ka ion metal dị arọ. Site na njirimara cationic ya dị elu, enwere ike iji ya na-ede akwụkwọ, ọgwụgwọ mmiri, ngwọta plating, dispersant na ubi ndị ọzọ.

3. Ukwuu reactive polyethylenimine n'ihi ukwuu reactive isi na nke abụọ amines, n'ihi ya, ọ nwere ike mfe meghachi omume na epoxy, acids, isocynate ogige na acid gases. N'iji ihe onwunwe a, enwere ike iji ya dị ka ihe na-emeghachi ihe epoxy, adsorbent aldehyde na onye na-edozi agba.

Kedu ihe a na-eji polyethylenimine eme ihe?

Polyethylenimine (PEI)bụ ngwakọta polymer bara ụba nwere ọtụtụ ojiji, gụnyere mana ọnweghị oke na:

1. Ọgwụgwọ mmiri na ụlọ ọrụ akwụkwọ. Dị ka onye na-ahụ maka mmiri mmiri, a na-eji ya na mpempe akwụkwọ na-adịghị anabata (dị ka akwụkwọ nzacha, akwụkwọ nzacha ink, akwụkwọ mposi, wdg), nke nwere ike ime ka ike mmiri dịkwuo mma ma belata mmebi nke nhazi akwụkwọ, ebe ọ na-eme ngwa ngwa. nzacha mmiri nke pulp na ime ka eriri dị mma dị mfe ịgbagharị.

2. Onye na-edozi agba. Ọ nwere ike njikọ siri ike maka ịcha mmiri acid na enwere ike iji ya dị ka onye na-edozi ihe mgbe ọ na-esiji akwụkwọ acid.

3. Mgbanwe eriri na ihe inyeaka agbaji. Maka ọgwụgwọ eriri, dị ka ihe agha ahụ, mgbochi ịkpụ gloves, eriri, wdg.

4. Ngwa eletrọnịkị. N'ebe a na-ahụ maka ngwá electronic, a pụrụ iji ihe nkiri polyethylene imide mee ihe dị ka oyi akwa dịpụrụ adịpụ, ihe mkpuchi na mkpuchi mkpuchi nke ihe ndị dị na kọmputa, wdg, na-arụ ọrụ mkpuchi dị mma na oke okpomọkụ.

5. Nkwakọ ngwaahịa nri. Dị ka ihe oriri nkwakọ ngwaahịa, ọ nwere uru nke mmiri-àmà, ezigbo gas na-eguzogide, na-adịghị egbu egbu, enweghị mmasị, elu okpomọkụ na-eguzogide, wdg, na ọtụtụ-eji na nkwakọ nke anụ, anụ ọkụkọ, mkpụrụ osisi, akwụkwọ nri, kọfị na ngwaahịa ndị ọzọ.

6. Ngwa ahụike. Enwere ike iji Polyvinylimine na ngwaọrụ ahụike, ngwaọrụ nyocha, nkwakọ ngwaahịa ahụike, wdg, dị ka akwa mkpuchi ahụike na ihe nkiri doro anya ọgwụ.

7. Nrapado. Dị ka ihe ntanye na-arụ ọrụ dị elu, a na-eji ya eme ihe na-emepụta ikuku, ihe eletriki eletrik, akụkụ ụgbọ ala na ihe ndị ọzọ.

8. Ndị na-ahụ maka ọgwụgwọ mmiri na ndị na-ekesa. A na-ejikarị ya eme ihe na ọgwụgwọ mmiri, ngwọta electroplating, dispersant na ubi ndị ọzọ. Onye na-ebu mkpụrụ ndụ ihe nketa. Polyvinylimide bụ vector na-abụghị nke nje maka nnyefe mkpụrụ ndụ ihe nketa, ọkachasị dabara adaba maka mbufe ọtụtụ plasmids.

Na mgbakwunye,polyethyleniminenwekwara ihe e ji mara elu adhesion, elu adsorption, high cation, high reactivity, etc., a na-ejikarị ya eme ihe n'ubi agba, ink, nrapado, eriri eriri, ọgwụgwọ nsị na ihe ndị ọzọ.

N'ozuzu, polyvinylimide bụ polymer vasatail nwere ọtụtụ ngwa ngwa, na ihe onwunwe ya nwere ike gbanwee ma kwalite ya site n'ịgbanwe ịdị arọ molecular, nhazi na ịrụ ọrụ.
