Ungakuvimbela kanjani unamathisela u-aluminium kusuka ku-oxidizing?
Kumiswa ukuhlanganiswa okuqinile futhi okuzinzile ebusweni be-aluminium powder, ngaleyo ndlela kuvinjelwe i-oxidation ye-aluminium powder. I-aluminium alluble aluminium paste isebenzisa uphethiloli njengokugaya okuphakathi futhi ingeza ifilimu evikela i-hydrophilic (efana nePingpingJia, njll.) Ngokugaya. Ifilimu evikela i-Hydrophilic yakha isendlalelo sedwa ebusweni be-aluminium powder, engavimbi nje kuphela i-oxidation kodwa futhi igcina ukucaciswa okuphezulu kwe-aluminium. Kunganciphisa futhi ukungezwani kwe-aluminium powder kwamanzi, ukufeza inhloso yokuhlakazeka kwama-electrolyte aqinile. Lolu hlobo lwefilimu evikelayo luphinde lwenze i-aluminium paste emulsion, engasetshenziswa ngqo futhi kalula noma uphethiloli usetshenziswa njengemiphakathi egayayo. Ukuvela kwalolu hlobo lwe-aluminium paste kuma-granule athambile amnyama amnyama anephunga likaphethiloli omncane. Ubuningi obusezingeni eliphakeme bumayelana ne-∥cm3. Kuzinzile emoyeni owomile futhi kunokuqina okubuthakathaka. Ama-flash flakes anama-adhesion, kepha awonakali kakhulu ukugeza ngamanzi abandayo. Bahlakazeka ngemuva kokuhlangana namanzi futhi kulula ukusabela ngama-acid aqinile kanye ne-alkalis. Izici eziyinhloko ze-aluminium paste:
1. Okuqukethwe okuqinile kungama-65%, kanye nokuqukethwe okusebenzayo kwe-aluminium kokuqukethwe okuqinile akunasilinganiso esingaphansi kwama-85%.
2. I-aluminium powder ibonwa, ngemibimbi futhi igoba ebusweni, futhi imiphetho iyachotshozwa. Inendawo enkulu, futhi indawo yayo yokumboza amanzi ingaphezulu kuka-4000cm3 / g. Ubukhulu bezinhlayiya buhlolwe ku-701xm (ama-mesh angama-200), kanye nezinga lokungena nge-98%. Ukwakheka kwalo okuyizinhlayiyana yile: 10-15¨m ama-akhawunti we-15-10%, ama-20-25izm ama-akhawunti angu-10%, nangaphezulu kwe-10%.
3. Ine-permeability yamanzi enhle futhi yakha ngokushesha uketshezi oluhlanganisiwe oluhlanganisiwe ngaphansi kwamandla angaphandle avusa. Lapho ibekwa namanje, i-aluminium powder izocima kancane kancane, kepha kulula kakhulu ukuvusa futhi, ngaphandle kwe-agglomeration noma isikhutha.
4. Ingagcinwa esimweni esivalwe cishe izinyanga eziyi-6, futhi ukucaciswa kwayo nokuvumela ngeke kushintshe.
