Uburyo bwo gutegura aluminium

Bitewe nuburyo butandukanye bwo gutegura, ifuro ya aluminiyumu irashobora gushyirwa mubice bifunze-selile ya aluminiyumu, igice-gufunga-selile aluminium ifuro, no gufungura-selile aluminium ifuro ukurikije uko imyobo ihujwe. Uburyo bwo gutegura ifuro ya aluminiyumu irashobora gushyirwa mubice bitatu: icyiciro cyamazi, icyiciro gikomeye, no kubitsa.

(1) Uburyo bwicyiciro cyamazi

Uburyo bwa feri-feri nuburyo bukuze bwo gutegura bwa aluminiyumu, hamwe nubushakashatsi bwagutse hamwe nibyifuzo byo gukoresha, cyane cyane gaze ihumeka muburyo bwamazi yicyuma, uburyo bwo gutumura ibyuma byuma, uburyo bwo gushora imari, hamwe nuburyo bwo guta amazi.

Gazi ihumeka muburyo bwamazi yicyuma: mumashanyarazi ya aluminiyumu yashongeshejwe wongeramo ibice byibyimbye, kugirango urusheho kwiyegeranya gushonga, ibisanzwe bikoreshwa cyane bifite karubone ya silicon, oxyde ya alumina magnesium, nibindi, hanyuma, mubyuma byashongeshejwe mukirere, azote , hydrogène, cyangwa imvange ya gaze, kandi bigahora bikurura, icyuma gishongeshejwe gishobora kuboneka nyuma yo gukonjesha ububobere bwa 80% ~ 97.5% bya aluminiyumu, nkuko bigaragara ku gishushanyo 1.

. % ya porosity ya aluminiyumu. Umukozi wo kubira ifuro ukoreshwa mu gukoraaluminiumTiH2, ZrH2, na CaH2, nibindi.

. uku guta, gukonjesha no gukomera kugirango ukureho ibikoresho bivunika, urashobora kubona porosity ya 80% ~ 97% ya aluminiyumu.

. Cyangwa ialuminium. Ibisanzwe byuzuza ni umunyu ushonga, imipira ya ceramic idashobora gukemuka, imipira ya corundum yuzuye, karuboni ya furo, nibindi. Ubu buryo bushobora kugabanywamo ubwoko bubiri: uburyo bwo gutera hejuru-igitutu cya percolation hamwe nuburyo bwo guta igitutu bubi.

2. Uburyo bukomeye

. byongeye gutunganywa, nko kuzunguruka, guhimba, nibindi, hanyuma iki gicuruzwa kirangiye gishyirwa mubyuma bisabwa, bigashyuha mubushyuhe runaka kuburyo umukozi uhuha yangirika kugirango akore ibibyimba kandi abone aluminium ifuro. Ubu buryo buragoye, ariko ubwiza bwibicuruzwa buri hejuru kandi imikorere irahagaze, bityo itera imbere byihuse, ariko ubu buryo ntibushobora kubyazwa umusaruro bitewe nigiciro kinini cyibikoresho fatizo.

. Ubushyuhe bwumuriro bwibikoresho bya polymer, ibikoresho bya spongy muburyo bwo kubora kugirango bigire uruhare rwigihe gito, hanyuma ifu ya aluminiyumu iracumizwa hamwe, hanyuma ikonjeshwa kugirango ibone porosity ya 70% kugeza 90% ya Aluminium ifuro.

. komeza kubyutsa no gukonjesha kuburyo buhagije, hanyuma utere icyitegererezo kugirango ubone ibyuma-umupira wibikoresho. Iyo ibikoresho byongeweho umupira nibintu byoroshye, uburyo bwo koza kwibiza burashobora gukoreshwa mugushonga ibikoresho byumupira, kugirango unyuze mu mwobo wo mu bwoko bwa aluminium.

3. Uburyo bwa electrodeposition

Ifuro nuburyo bwo kuyobora nkibikoresho bya cathode, isahani yuzuye ya aluminiyumu yinganda kubikoresho bya anode, mu isahani ya alkyl aluminium, ku buryo aluminiyumu yashyizwe hejuru y’ifuro, nyuma yo gukama ku bushyuhe runaka bwangirika, kubora ubushyuhe bwa ifuro,aluminium. Ubu buryo buragoye kandi bukeneye guhindura ibihinduka, ariko imiterere ya furo irasa. Imiterere ya fumu ya aluminium yateguwe nuburyo bwa electrodeposition irerekanwa mumashusho 2.
