Imiphi imiphumela ye-aluminium powder ekukhiqizweni kokhonkolo okuhleliwe?
Okuqukethwe kwe-aluminium ye-aluminium powder ngokuvamile kuyadingeka ukuba kungabi ngaphansi kwama-98%, futhi okuqukethwe okusebenzayo kwe-aluminium akusekho ngaphansi kwama-89%. Enqubweni yokukhiqiza yemikhiqizo ekhonkolo ebekiwe, izici eziningi ze-aluminium powder kwinqubo yokukhiqiza zithinta ikhwalithi yemikhiqizo ekhonkolo ebekiwe. Ngoba i-aluminium powder ingasabela ngamanzi, isusa i-hydrogen emanzini futhi ikhiqize i-aluminium oxide eqinile, ingaphezulu le-aluminium oxygen emoyeni ngenxa yokuvezwa komoya ngenxa yokuvezwa kwe-aluminium ekuxhumaneni kwamanzi .
Kunenani elithile lezinto ze-alkaline ezinjenge-calcium hydroxide ku-slurry ekhonkolo evuthayo, futhi i-aluminium oxide ingachithwa kwikhambi le-alkaline ukwenza i-metaaluminate. Lapho ifilimu ye-oxide ebusweni be-aluminium powder iyachithwa, i-aluminium yensimbi iphendula ngamanzi, ikhipha i-hydrogen emanzini, futhi ikhiqiza i-aluminium hydroxide. Kodwa-ke, njenge-aluminium oxide, futhi kuvimbela ukuxhumana phakathi kwamanzi kanye nobuso be-aluminium yensimbi, ukuze ukusabela kungakwazi ukuqhubeka. Kodwa-ke, i-aluminium hydroxide nayo ingachithwa kwikhambi le-alkali ukuze wakhe i-metaaluminate. Ngale ndlela, kwikhambi le-alkali, i-aluminium powder ingaqhubeka nokuphendula ngamanzi ukukhiqiza i-hydrogen kuze kuqedwe i-aluminium yensimbi. I-hydrogen isatshalaliswa ngokulinganayo ku-slurry ngesimo sama-bubble acishe abe yi-spherical, ebangela ukuba ivolumu ye-slurry ikhulise futhi yakha umkhiqizo we-porous silingle ngemuva kokuqina. Inani le-aluminium powder esetshenziswe kukhonkolo olwenziwe kahle linqunywa ngenani le-aluminium esetshenzisiwe. Inani le-aluminium powder esetshenzisiwe libhekisela kwivolumu ye-hydrogen ekhiqizwa ukusabela okugcwele kwe-aluminium powder ngeyunithi ngayinye ngamanzi ngaphansi kwezimo ezijwayelekile. Isizukulwane segesi se-Theoretical of 1g se-aluminium yensimbi ngaphansi kwezimo ezijwayelekile yi-1.24l. Kodwa-ke, i-aluminial aluminium powder ihlala inenani elincane lokungcola, futhi i-aluminium ethile i-oxidised ukwakha i-aluminium oxide, eyenza isizukulwane sangempela segesi ye-aluminium powder ephansi kunenani le-aluminium liphansi kunenani le-aluminium liphansi kunenani le-aluminium liphansi. Ngokusobala, okuqukethwe kwensimbi ye-aluminimumu ngokwengeziwe e-aluminium powder, okukhulu kakhulu igesi. Ku-slurry ekhonkolo evulekile Ngakho-ke, i-aluminium powder esetshenzisiwe kukhonkolo ohleliwe ivame ukukhiqizwa nge-aluminium ebuhlungu kakhulu.
UJiangsu Jiali Technology Technology Co, Ltd.is Ifektri etholakala eScaquan, China. Okukhethekile ekukhiqizeni i-aluminium paste, njengokunamathisela kwe-aluminium ngokhonkolo ohleliwe, i-aluminium paste ye-aerated brick, i-aluminium paste ye-ALC Board, njll.
