  • Isibonelo:Sebenzisa ekuqedeni okungeyona i-iron ezindwangu.

4. Ama-Hydrogel kanye nezicelo ze-Biomedical

  • Iqhaza le-DAAM:Inomthelela ekwakhiweni kwama-hydrogel ahambisanayo.
  • Isibonelo:Amasistimu okulethwa kwezidakamizwa alawulwayo.

5. Iphepha nokupakisha

  • Iqhaza le-DAAM:Inikeza amandla athuthukisiwe kanye nezakhiwo zokuvimbela umswakama.
  • Isibonelo:Izingubo zephepha ezikhethekile zokupakisha ukudla nesiphuzo.

6. Ama-sealants

  • Iqhaza le-DAAM:Ithuthukisa ukuguquguquka nokumelana nokuqhekeka ngaphansi kwengcindezi.
  • Isibonelo:Ama-sealant ashintshwe nge-silicone okwakhiwa kanye nezicelo zezimoto.

Izinzuzo Zokusebenzisa i-DAAM

  1. Amandla Okuxhumanisa Okuhlukahlukene:Yakha amanethiwekhi aqinile anama-cross-linkers asuselwa ku-hydrazide njenge-ADH.
  2. Ukuqina Kokushisa:Iqinisekisa ubuqotho ngaphansi kwezimo zokushisa eziphezulu.
  3. Ukumelana Nomswakama:Idala amafilimu nezakhiwo ezixosha amanzi.
  4. Ubuthi obuphansi:Kuphephile ukusebenzisa uma kuqhathaniswa namanye ama-monomers.
  5. Ukuhambisana Okubanzi:Isebenza ngamasu ahlukahlukene we-polymerization, kufaka phakathi i-emulsion, ukumiswa, nezinqubo zesixazululo.

Ukuhambisana ne-Adipic Dihydrazide (ADH)

Inhlanganisela ye-DAAM ne-ADH isetshenziswa kakhulu ezinhlelweni ze-polymer ezixhumene. Ukusabela phakathi kweqembu le-ketone le-DAAM neqembu le-hydrazide ku-ADH kuphumela ekuxhumekeni okuhlala isikhathi eside kwe-hydrazone, okuvumela:

  • Amandla emishini athuthukisiwe.
  • Ukumelana nokushisa okuphezulu.
  • Ukuvumelana nezimo kuye ngezidingo zokwakheka.

Indlela yokusabela:

  1. Ukusebenzisana kweKetone-Hydrazide:I-DAAM + ADH → I-Hydrazone Bond
  2. Izicelo:Izembatho ze-polyurethane ezitholakala emanzini, izinto zokuziphilisa, nokunye.
