Ifektri ye-adipic dihydrazide (ADH) efektri

I-Adipic Dihydrazide (ADH) iyingxenye esetshenziswayo esetshenziswa kabanzi njenge-ejenti exhumanisa ngokuwela kuma-polymers, embonweni, kanye nokunamathela. Amandla awo okuphendula nge-ketone noma ngamaqembu e-Aldehyde, akha ukuxhumana okuzinzile kwe-hydrazone, kwenza kube yinto ebaluleke kakhulu kuzicelo ezidinga izibopho eziqinile zamakhemikhali kanye nokuqina okushisayo. I-ADH futhi isebenza njengesengezo sokwenza ngcono izakhiwo zemishini kanye nokumelana kwemvelo kwezinto zokwakha.

Izici zamakhemikhali ze-ADH

Amaqembu asemqoka asebenzayo

  1. Amaqembu e-Hydrazide (-nH-NH2):Thatha kalula ngama-ketones nama-aldehydes ukwakha izibopho ze-hydrazone.
  2. I-adipic acid backbone:Inikeza ukuqina kwesakhiwo kanye nokuvumelana nezimo ezinhlelweni ezixhumene kakhulu.

Izicelo ze-ADH

1. Umenzeli oxhumanisayo

  • Indima:I-ADH isetshenziswa kabanzi ama-polymers wesixhumanisi ngokuphendula ngama-ketones noma ama-aldehydes, adala ukuxhumana okuqinile kwe-hydrazone.
  • Izibonelo:
    • Ama-hydrogels axhumeke ngokuqondile wokusebenzisa i-biomedical.
    • Ukuhlukaniswa kwe-polyurene polyurethane ezimbobeni zezimboni.

2. Ukumboza

  • Indima:Izenzo njenge-hardener ne-cross-linerer ukuze uthuthukise ukunamathela, ukuqina, kanye nokumelana kwamanzi kupende kanye nokumboza.

  • Isibonelo:Ama-hydrogels axhumeke ngokunqamula kwemithi ekhishwa ngemikhumbi.

5. Ukwelashwa kwamanzi

  • Indima:Usebenza njenge-ejenti yokupheqa amasistimu we-waterne, enikeza ukuphendula okuphezulu ekushiseni kwegumbi.

6. I-Chemical Indermite

  • Indima:IMISEBENZI Njengomphakathi oyisihluthulelo ekuhumushweni kwamakhemikhali akhethekile namanethiwekhi we-polymer.
  • Isibonelo:Ama-poldloobic noma ama-hydrophilic actionmers asebenza.

Indlela Yokuphendula

Ukuhlelwa kwe-Hydrazone Bond

I-ADH isabela nge-ketone noma amaqembu ama-Aldehyde ukwakha ama-hydrazone bond ngokusebenzisa ukusabela okuvuthayo, okubonakaliswa yi:

  1. Ukususwa kwamanzi njengokukhipha.
  2. Ukwakheka kokuxhumana okuzinzile okuqinile.

Ukusabela:

 

Lokhu kusabela kubalulekile ekwakheni izinto zokwakha ezinokumelana okuphezulu ekucindezelweni ngomshini, okushisayo, kanye nemvelo.

Izinzuzo zokusebenzisa i-ADH

  1. Ukuqina kwamakhemikhali:Amabhondi e-Hydrazine akhiwa yi-ADH amelana kakhulu ne-hydrolysis kanye nokonakaliswa.
  2. Ukumelana nokushisa:Kuthuthukisa ukuqina okushisayo kwezinto zokwakha.
  3. Ubuthi obuphansi:Kuphephile uma kuqhathaniswa nezinye izixhumanisi ezingemthetho.
  4. Ukuvumelana kwamanzi:I-Solubity emanzini yenza ukuthi ilungele ukwakheka kwe-eco-friendly, amanzi.
  5. Okuhlukahlukene:Ihambisana nezinhlobonhlobo zama-polymer matric namaqembu asebenzayo.

Ukucaciswa kobuchwepheshe

  • Ukumsulwa:Imvamisa iyatholakala ngamazinga wokuhlanzana we-98-99%.
  • Okuqukethwe umswakama:Ngaphansi kuka-0.5% ukuqinisekisa ukuvumelanisa okungaguquki.
  • Usayizi wezinhlayiyana:I-powder ecolekile, lula ukusakazwa okulula nokuxuba.
  • Izimo Zokugcina:Gcina endaweni epholile, eyomile, futhi enomoya omuhle, ukugwema ukubonwa okuqondile kwelanga kanye nomswakama.

Izitayela zemakethe kanye nezimboni

1. Ukugxila kokuqina

Ngokushintshwa kwemikhiqizo enobungane bemvelo, iqhaza le-ADH ekusungulweni kwamanzi kanye nokwakheka okuphansi kwe-voc kuye kwagqama. Isiza ekuhlangabezaneni nemigomo yemvelo eqinile ngenkathi ihambisa ukusebenza okuphezulu.

2. Ukukhula kwe-biomedical

Amandla ka-Adh okwakha ahambisane ahambisanayo futhi ahlehlise ama-hydrogels abeka phambili ukwandisa izindima ekunikezelweni kwezidakamizwa, ubunjiniyela bezicubu kanye nakuzokwelashwa.

3. Isidingo Zomkhakha Wezokwakha

Ukusetshenziswa kuka-Adh ku-sealants esebenza kakhulu kanye nokunamathelayo kuqondanisa nesidingo esikhulayo sezinto zokwakha ezihlala isikhathi eside, ezivimbela isimo sezulu.

4. R & D nge-nanotechnology

Ucwaningo Olusafufusa luhlola i-ADH ngokuxhumeka kwesiphambano ezintweni zokwenziwa kwama-nanosktured, ukuthuthukisa izakhiwo zemishini nele-thermal zezinhlelo eziyinhlanganisela.

Ukuphatha nokuphepha

  • Izindlela zokuzivikela:Gqoka amagilavu, ama-goggles, kanye nemaski lapho uphatha ukugwema ukucasuka noma ukuphefumula.
  • Izindlela zosizo lokuqala:
    • Ukuphefumula: Thuthukela emoyeni omusha bese ufuna ukunakekelwa kwezokwelashwa uma kuqhubeka izimpawu.
    • Ukuxhumana kwesikhumba: Geza kahle ngensipho nangamanzi.
  • Ukuchitheka:Qoqa usebenzisa impahla yokumunca i-inert bese ulahla ngokuya ngemithetho yendawo.

Ifektri ye-HEC

I-Adipic Dihydrazide (ADH) i-ejenti enamandla exhumanisa nesiphambano esinamandla futhi esiphakathi nezicelo ezibanzi kuyo yonke imboni. Ukuqina kwayo kwamakhemikhali, ukusebenziseka, kanye nokuhambisana nezidingo zesimanje zokusimama kwenza kube yingxenye ebucayi ekunamatheleni, embonweni, izinto zokufunda, nangale kwalokho. Njengoba ubuchwepheshe buvela, ukuhambisana kuka-Adh ekuthuthukiseni izinto ezisezingeni eliphezulu kuyaqhubeka ukwandisa, kugcizelela ukubaluleka kwaso kuzo zombili izimakethe zamanje nezivela.
