Menene polyethylenimine ake amfani dashi?

Polyethylenimine (PEI)wani fili ne na polymer mai iya aiki tare da amfani iri-iri, gami da amma ba'a iyakance ga:

1. Maganin ruwa da masana'antar takarda. A matsayin wakili mai ƙarfi jika, ana amfani da ita a cikin takarda mai shayarwa mara nauyi (kamar takardar tacewa, takarda tawada, takarda bayan gida, da sauransu), wanda zai iya inganta rigar takarda da kuma rage lalacewar sarrafa takarda, yayin da take hanzarta aiwatar da aikin. tace ruwa na ɓangaren litattafan almara da kuma sanya filaye masu kyau da sauƙi don flocculate.

2. Wakilin gyara launi. Yana da ƙarfin ɗaure mai ƙarfi don rini na acid kuma ana iya amfani dashi azaman mai gyarawa lokacin rini na acid rini takarda.

3. Fiber gyare-gyare da rini auxiliaries. Don maganin fiber, irin su sulke na jiki, safofin hannu na hana yanke yankan hannu, igiya, da sauransu.

4. Kayan lantarki. A fagen kayan lantarki, ana iya amfani da fim ɗin polyethylene imide azaman mai warewa, kayan rufewa da suturar kayan aikin lantarki, da dai sauransu, tare da kyakkyawan aikin haɓakawa da juriya mai zafi.

5. Kayan abinci. A matsayin kayan abinci na kayan abinci, yana da fa'idodi na tabbatar da danshi, juriya mai kyau na iskar gas, mara guba, mara daɗi, juriya mai zafi, da dai sauransu, kuma ana amfani da shi sosai a cikin marufi na nama, kaji, 'ya'yan itatuwa, kayan marmari, kofi da sauransu. sauran kayayyakin.

6. Kayan aikin likita. Ana iya amfani da Polyvinylimine a cikin na'urorin likita, kayan aikin bincike, marufi na likita, da sauransu, kamar su tufafin likita da fina-finai na likita.

7. M. A matsayin manne mai babban aiki, ana amfani da shi wajen kera sararin samaniya, kayan lantarki, sassan mota da sauransu.

8. Magungunan maganin ruwa da masu rarrabawa. An yadu amfani a papermaking ruwa magani, electroplating bayani, dispersant da sauran filayen. Mai ɗaukar Gene. Polyvinylimide vector ne wanda ba na hoto ba ne don isar da kwayoyin halitta, musamman dacewa da haɗin kai na plasmids da yawa.

Bugu da kari,polyethylenimineHakanan yana da sifofin mannewa mai yawa, yawan talla, cation mai girma, haɓaka aiki da sauransu, kuma ana amfani da shi sosai a fagen fenti, tawada, adhesive, maganin fiber, maganin najasa da sauransu.

Gabaɗaya, polyvinylimide wani nau'in polymer ne mai mahimmanci tare da aikace-aikacen da yawa, kuma ana iya daidaita kaddarorinsa da haɓaka ta hanyar canza nauyin kwayoyin halitta, tsari da aiki.
