Ukubhala impendulo ye-aluminium powder
Ubuninzi obuthile be-aluminium yi-2.7 kuphela. Phantsi kweemeko ezisemgangathweni, 1.24 L ye-hydrogen iveliswa yonke i-1 g ye-aluminium. Ke ngoko, isixa esisetyenzisiweyo sincinci kwaye iindleko ziphantsi. Iziphumo ze-aluminium zinkulu kwaye umthombo ulubanzi kakhulu. Isetyenziselwa ukuveliswa kwekhonkrithi ye-aepered kwaye kulula ukulawula ngokwemigaqo yenkqubo. Yeyona nto isetyenziswayo isetyenziswayo ekufumaneni. I-aluminium yintsimbi esebenzayo kakhulu. Inokusabela nge-acid yokutshintsha i-hydrogen kwi-acid, kwaye inokusabela ngeAlkali ukuba isebenze. I-Alumuminum yentsimbi ilula i-oxidod ukwenza i-aluminium oxide emoyeni. Ifomula yokuphendula yile ilandelayo:
4Al 3o2 2o3o3
I-Aluminium Oxide ihleli emoyeni kunye namanzi. Iimveliso ze-aluminium esiyisebenzisayo kubomi bethu bemihla ngemihla zinefilimu yokukhusela i-almininum oxide, ethintela i-oxination yentsimbi yentsimbi. Nangona kunjalo, ialuminium oxide inokusabela nge-acid okanye i-alkali kwindalo ye-acidic okanye ialkaline ukwenza iityuwa ezintsha, ukutshabalalisa umaleko okhuselayo.
Al2o3 6h = 2h2o 3h2o
Al2o3 20h- = 2 i12o3 h2o
I-Alumic Aluminiyam iphikisana namanzi, ukubonakalisa i-hydrogen emanzini nasekuveliseni i-Aluminium hydroxide.
2l 6h2o = 2al (oh) 3 3h2 ↑
Ukuvelisa i-Aluminium ye-Aluminum ye-Aluminium esiyisebenzisayo ihlala inayo i-subrecle subleres, eyenza ifilimu ye-aluminium oxide oxies exineneyo ethintela i-aluminium ekunxibelelaneni namanzi onxibelelana namanzi onxibelelana. Kuphela kusemva kwefilimu ye-oxide isuswe yi-Aleminium powder iphendule kwaye ikhuphe i-hydrogen emanzini. Ke ngoko, sithi i-Aluminium powder, njengearhente yokuvelisa igesi, inokusebenza kuphela kwi-Alkaline evelisa kwindawo yeAlkaline.
I-al (oh) i-3 eveliswe yi-Aluminiyam kunye namanzi yinto efana nejeli, enokuthi ithintele ngakumbi i-genin kunye ne-aluminium, kodwa i-A1 (O) ikwanokunyibilikisa isisombululo seAlkaline ukuvelisa i-Alkaline:
Al (oh) 3 oh- = i-A1o2- 2h2o
Ngale ndlela, kwindawo ye-alkaline, i-aluminium inokuphinda iphendule ngamanzi ukuvelisa i-hydrogen kude kube kuchithwa i-alminum yentsimbi.
Kwikhonkrithi yekhonkrithi yekhonkrithi, into ye-alkaline yi-CA (O) 2. Ke ngoko, impendulo ye-Aluminium powder kunye namanzi inokubhalwa njenge:
I-2al 3ca (oh) 2 6h2o = 3cao? I-al23? 6h2o 3h2 ↑
I-JiangSU Jiai yeTekhnoloji yeTekhnoloji Co., Ltd.is umzi-mveliso waseSuqian, China. Ikhethekileyo ekuveliseni i-Aluminium Paste, efana ne-aluminium Passing yekhonkrithi, i-Aluminium Passing Brick, iAluminium Paste yeBhodi ye-ALC, njl.
