Polyethylenemine (PEI)ipolymer inonyungudika mumvura. Kuwanda kwemvura muzvigadzirwa zvekutengesa kunowanzova 20% kusvika 50%. PEI inoumbwa nepolymer kubva ku ethylene imide monomer. Ipolymer yecationic inowanzoonekwa semvura isina ruvara kusvika yero kana yakasimba ine huremu hwakasiyana-siyana hwemamorekuru uye mhando dzemaumbirwo.

Chiipolyethyleneiminebasa?

1. Kubatana kwakanyanya, boka remaamino rinonyudzwa zvakanyanya rinogona kuita neboka rehydroxyl kuumba hydrogen bond, boka reamine rinogona kuita neboka recarboxyl kuumba ionic bond, boka reamine rinogonawo kuita neboka recarbon acyl kuumba covalent bond. Panguva imwe chete, nekuda kwechimiro cheboka rayo repolar (amine) neboka rehydrophobic (vinyl), rinogona kusanganiswa nezvinhu zvakasiyana. Nesimba iri rakazara rekubatanidza, rinogona kushandiswa zvakanyanya muminda yekuvhara, inki, pendi, binder nezvimwewo.

2. Polyvinyl imide ine cationic yakawanda inowanikwa mumvura, iyo inogona kudzima nekunyudza zvinhu zvese zveanionic. Inobatsirawo kubvisa maion esimbi inorema. Nehunhu hwayo hwe cationic hwakawanda, inogona kushandiswa mukugadzira mapepa, kugadzirisa mvura, plating solution, dispersant nedzimwe nzvimbo.

3. Polyethylenimine ine simba guru rekuita zvinhu nekuda kwemaamine ekutanga neechipiri ane simba guru rekuita zvinhu, saka inogona kuita zvinhu zviri nyore ne epoxy, acids, isocyanate compounds uye magasi eacid. Ichishandisa hunhu uhwu, inogona kushandiswa se epoxy reactant, aldehyde adsorbent uye color fixing agent.

Polyethylenimine inoshandiswa pai?

Polyethylenemine (PEI)imusanganiswa wepolymer unoshandiswa zvakasiyana-siyana, kusanganisira asi kwete kungogumira pane:

1. Kurapa nemvura uye kugadzira mapepa. Senzira yekunyorovesa, inoshandiswa mumapepa asinganyorovese (akadai sepepa rekusefa, bepa rinodzima inki, bepa rechimbuzi, nezvimwewo), izvo zvinogona kuvandudza kunyorova kwemapepa uye kuderedza kukuvara kwekugadzirwa kwemapepa, ukuwo zvichikurumidzisa kusefa kwemvura mu pulp uye kuita kuti shinda diki dzive nyore kudhonzeka.

2. Mushonga wekugadzirisa mavara. Une simba guru rekubatanidza madhayi ane acid uye unogona kushandiswa semushonga wekugadzirisa kana madhayi ane acid achiisa dhayi papepa.

3. Kugadzirisa uye kudhaya fiber. Kurapa fiber, zvakaita sekudzivirira muviri, magirovhosi anodzivirira kucheka, tambo, nezvimwewo.

4. Zvinhu zvemagetsi. Munyaya yemagetsi, firimu re polyethylene imide rinogona kushandiswa sechikamu chekuparadzanisa, chinhu chinodzivirira kupisa uye chikamu chinofukidza zvikamu zvemagetsi, nezvimwewo, nekushanda zvakanaka kwekudzivirira kupisa uye kudzivirira kupisa kwakanyanya.

5. Kurongedza chikafu. Sechigadzirwa chekurongedza chikafu, chine zvakanakira zvekuti hachipindi hunyoro, hachipindi gasi zvakanaka, hachina chepfu, hachina kunaka, hachipindi tembiricha yepamusoro, nezvimwewo, uye chinoshandiswa zvakanyanya mukurongedza nyama, huku, michero, miriwo, kofi nezvimwe zvigadzirwa.

6. Zvinhu zvekurapa. Polyvinylimine inogona kushandiswa muzvishandiso zvekurapa, zvishandiso zvekuongorora, kurongedza kwekurapa, nezvimwewo, zvakaita semadressing ekurapa uye mafirimu ekurapa akajeka.

7. Kunamira. Sekunamatira kunoshanda zvakanyanya, kunoshandiswa mukugadzira zvinhu zvemuchadenga, zvikamu zvemagetsi, zvikamu zvemotokari nezvimwewo.

8. Mishonga yekurapa nemvura uye mishonga inoparadzira mvura. Inoshandiswa zvakanyanya mukugadzira mapepa ekurapa mvura, electroplating solution, dispersant nedzimwe nzvimbo. Gene carrier. Polyvinylimide inodzivirira utachiona pakuendesa majini, kunyanya yakakodzera kubatanidza maplasmid akawanda.

Pamusoro pe,polyethylenimineine hunhu hwekunamatira kwakanyanya, kunyungudika kwakanyanya, cation yakawanda, reactivity yakawanda, nezvimwewo, uye inoshandiswawo zvakanyanya muminda yependi, inki, namira, kurapwa kwefiber, kurapwa kwetsvina nezvimwewo.

Kazhinji, polyvinyllimide ipolymer inoshandiswa zvakasiyana-siyana ine mashandisirwo akasiyana-siyana, uye hunhu hwayo hunogona kugadziriswa nekugadziriswa nekuchinja huremu hwemamorekuru, chimiro uye mashandiro ayo.
