1.Kuva mu myaka ya za 1960---1963, umuhanga mu bya siyansi w’Umunyamerika Schwartzwalder yavumbuye uburyo bwo gutera ifuro ry’umwimerere. Ifuro ry’ibumba ryabonetse binyuze mu gutera ifuro ry’umwimerere mu gusya ifuro ry’umwimerere no gukuraho ifuro ry’umwimerere ku bushyuhe bwinshi, hashyirwaho ihame ry’ingenzi ryo gutegura ifuro ry’ibumba (ririmo urufatiro rwa alumina), ari na ryo soko y’ubuhanga bw’ifuro ry’ibumba rya alumina.
2.Kuva mu myaka ya za 1970---1978, Mollard FR na Davidson N bo muri Leta Zunze Ubumwe za Amerika bateye imbereakayunguruzo k'ifuro rya alumina ceramicbishobora gukoreshwa mu kuyungurura aloyide hakoreshejwe uburyo bwa organic foam impregnation hamwe na alumina na kaolini nk'ibikoresho by'ibanze, bikongera cyane ireme ry'ibicuruzwa bicukurwamo kandi bigabanya igipimo cy'ibisigazwa, bigaragaza ko utubumbe twa ceramic twa aluminium oxide foam twinjiye ku mugaragaro mu nganda kandi bigateza imbere iterambere ryabyo ku rwego runini.
3.Mu myaka ya za 1980---Uburayi, Leta Zunze Ubumwe za Amerika, Ubuyapani n'ibindi bihugu byahanganye mu bushakashatsi no guteza imbere ibikoresho bitandukanye n'ibipimo byabyo. Umusaruro wazamuwe mu buryo bwo gukoresha imashini no gukora ikoranabuhanga, kandi ibicuruzwa byashyizwe mu byiciro kandi bigenwa mu buryo busanzwe.
Ubushinwa bwatangiye ubushakashatsi ku bumba rya alumina mu ntangiriro z'imyaka ya 1980. Kaminuza ya Harbin y'ikoranabuhanga, ikigo cya Shanghai Institute of Machinery Technical Technical Shanghai n'ibindi bigo byafashe iya mbere mu gukora imirimo ijyanye n'ibyo, buhoro buhoro bigeraho ubwigenge mu ikoranabuhanga no mu iterambere ry'inganda, kandi bigabanya icyuho ku isoko mpuzamahanga.
Uburyo busanzwe ni ugutera ifuro ry’umwimerere kandi intambwe ni izi zikurikira:
1. Gutegura urusenda:Vanga ifu ya alumina, umuyoboro, umusemburo wo gukata, umuti wo gukaraba n'amazi, uvange kugira ngo habeho urusenda rumwe rufite ingano ikomeye kandi rufite ubushyuhe buke.
2. Gutera no kumanika ibinure:Shyiramo ifuro ry’umwimerere ryakozwe mbere (nk’ikimenyetso cya polyurethane) mu gitereko, hanyuma utume igitereko gifata ku rukuta rw’umwobo w’igitereko cy’ifuro ku buryo bungana binyuze mu gusohora no kuzunguruka kugira ngo ukureho igitereko cy’ikirenga.
3. Kumisha no gukosora:Shyira igice cy'ifuro nyuma yo gusya mu ziko ryumutse hanyuma ugishyire ku bushyuhe bwa 80 - 120 ℃ kugira ngo gikomere, wongere imbaraga z'umubiri kandi wirinde kwangirika mu gihe cyo kuvura nyuma.
4. Gukuraho amavuta no gusohora kole:Shyira umubiri w'icyatsi kibisi wumye mu itanura rishyushya hanyuma uwushyushye kuri 400 - 600 ℃ kugira ngo utume imiterere y'ifuro ry'umwimerere n'icyuma gifunga ibintu bibora burundu kandi bihinduke kugira ngo bikore umubiri w'icyatsi kibisi ufite imyenge. Muri iki cyiciro, ni ngombwa kugenzura umuvuduko w'ubushyuhe kugira ngo wirinde ko umubiri w'icyatsi kibisi ucika.
5. Gushyushya ubushyuhe bwinshi:Umubiri w'icyatsi kibisi wakuwemo amavuta ushyushywa kugeza kuri 1400 - 1600 ℃ kugira ngo utwike, bityo uduce twa aluminium oxide tugakora reaction ikomeye, ibinyampeke bikura kandi bihurira hamwe, bigakora skeleton ikomeye cyane ya ceramic, amaherezo bikabona utubumbe twa aluminium oxide foam ceramic.
6. Gutunganya nyuma yo gukora:Kata, sukura, kandi usukure hakurikijwe ibisabwa kugira ngo ubone ibicuruzwa byarangiye bifite ingano n'ubuhanga bwagenwe.
1. Ubwinshi bw'imyenge:Ubusanzwe imyenge iri hagati ya 60% na 90%, kandi ingano y'imyenge ishobora guhindurwa (kuva kuri mikorometero icumi kugeza kuri milimetero nke), hamwe n'imyenge ifatanye.
2. Ubucucike buke:Ubucucike bw'ibice byinshi ni 0.3-1.2 g/cm³ gusa, buri hasi cyane ugereranije n'ubw'ibice by'icyuma bya alumina (hafi 3.95 g/cm³).
3. Ubudahangarwa bw'ubushyuhe bwinshi:Ubushyuhe bwo gukoreshwa mu gihe kirekire bushobora kugera kuri 1200-1600 ℃, igihe gito gishobora kwihanganira ubushyuhe bwinshi bwa 1800 ℃, kidashonga cyangwa ngo cyoroshye.
4. Ubudahangarwa ku ngaruka:Ubudahangarwa bw'aside na alkali (usibye ibyuma bikomeye bya alkali), ubudahangarwa bw'imiti, kurusha ibikoresho bifite imyenge y'icyuma.
5. Imikorere myiza yo kuyungurura:Imiterere y'umwobo uhujwe ishobora gufata neza uduce duto tw’amazi mu mazi dufite ubushobozi buke bwo guhangana n’amazi.
6. Gukingira ubushyuhe:Ubwinshi bw'imyenge bubangamira uburyo ubushyuhe butwara n'uburyo bunyuramo, bigatuma iba ibikoresho byiza cyane byo gukingira ubushyuhe bwinshi.
7. Ingufu ziciriritse za mekanike:Imbaraga zo gukanda no gukomera kw'ingufu byujuje ibisabwa mu nganda, kandi bifite ubukana runaka, butoroshye kwangirika.
8. Uburyo bwo guhindura ibintu mu buryo bukomeye:Ingano zitandukanye, imiterere na PPI bishobora guhindurwa bityo bigashobora guhaza ibyifuzo by'ibikoresho bitandukanye.
- Ahantu ho kuyungurura ubushyuhe bwinshi
1. Gutunganya icyuma gishonga:Iyo ikora ibyuma bidafite feri nka aluminiyumu, umuringa, zinki, nibindi, iyungurura ibintu birimo okiside n'uduce tw'imyanda mu gushonga kugira ngo yongere ubuziranenge bw'icyuma gikozwemo.
2. Gusukura imyuka ikoresha ubushyuhe bwinshi:ikoreshwa mu gukuraho imyuka ishyushye cyane mu nganda nko mu byuma, mu buhanga mu by'ubutabire, no gutwika imyanda, gukumira uduce tw'umukungugu no gusukura imyuka.
- Ahantu ho gukingira ubushyuhe
1. Ifuru y'inganda:Uburyo bwo gukingira umuriro mu itanura rya keramike, amatanura akoresha ibyuma, n'amatanura y'ibirahure kugira ngo bigabanye ubushyuhe no kuzigama ingufu.
2. Ibice by'ikirere:Nk'ibikoresho byo gukingira ibyogajuru na moteri, bishobora kwihanganira ubushyuhe bwinshi.
- Ikibuga cy'imodoka zitwara ibikoresho bya katalisiti
1. Gutunganya imyotsi iva mu modoka:Ishobora gushyirwamo katalisiti kugira ngo isimbure bimwe mu byuma bitwara ibintu, bikoreshwa mu guhindura ibintu byangiza mu mashini zisohora umwuka.
2. Katalisiyumu y'ibinyabutabire:Nk'ikintu gitwara ingufu mu gukora ibikorwa bya shimi, byongera aho ibikorwa bihurira kandi bikongera imikorere myiza ya catalytic.
- Izindi nganda
1. Kugabanya urusaku no kwinjiza amajwi:Ikoreshwa nk'ibikoresho bikurura amajwi mu bidukikije birimo ubushyuhe bwinshi n'ubukonje, nk'ibice bya moteri n'ibice by'ubushyuhe mu nganda.
2. Ubuvuzi bw'ibinyabuzima:Ibumba rya alumina rya foam rifite isuku nyinshi rishobora gukoreshwa nk'inkingi z'ubwubatsi bw'amagufwa, kandi rishobora guhuza neza n'ibinyabuzima.
