Umutekano w'inkongi ni ikibazo gikomeye mu nganda z'ubwubatsi, bituma hakenerwa ibikoresho birwanya inkongi cyane bishobora kwihanganira ubushyuhe bwinshi, gukwirakwira buhoro k'umuriro, no kugabanya ubushyuhe. Udupira twa mica tudashobora gushya, dufite ubushyuhe budasanzwe (bushobora kwihanganira ubushyuhe bugera kuri 1200°C), ubushobozi buke bwo gutwara ubushyuhe, n'ubushobozi budashya, byagaragaye nk'inyongeramusaruro y'ingenzi mu bwubatsi bw'ibikoresho bidashobora gushya. Bitandukanye n'ibintu bigabanya inkongi bishobora kurekura imyuka ihumanya iyo byatwitswe, udupira twa mica ni karemano, ntabwo ari uburozi, kandi bigumana imiterere yabyo ndetse no mu bushyuhe bwinshi, bigatuma biba byiza ku nzugi z'umuriro, amarido y'umuriro, n'ibikoresho byo gukingira inkuta.

Mu gukora inzugi z'inkongi y'umuriro, uduce twa mica tuvangwa n'udupira tw'ibiti cyangwa fibre y'ubutare kugira ngo hakorwe ibikoresho by'ibanze bidashobora gushya. Iyo 20%-30% by'uduce twa mica tudashobora gushya (ingano y'uduce 40-80 μm) twongewe ku bikoresho by'ibanze, igipimo cy'ubudahangarwa bw'umuriro bw'urugi rw'umuriro gishobora kongerwa kuva ku minota 30 kikagera ku minota 90-120. Ibi biterwa nuko uduce twa mica dukora urwego runini, rurinda ubushyuhe iyo ruhuye n'umuriro, rubuza ko ubushyuhe bwimuka kandi rukarinda urugi gushya cyangwa gusenyuka. Uruganda rukora ibikoresho by'ubwubatsi mu Bwongereza rwagerageje inzugi zacu z'inkongi y'umuriro zikoreshwa na mica mu buryo busanzwe bw'umuriro (ISO 834): inzugi zakomeje kuba nziza mu gihe cy'iminota 110, ubushyuhe bw'inyuma bugakomeza kuba munsi ya 140°C (urugero rwo gukwirakwira kw'umuriro), rurenze ibisabwa ku nzugi z'inkongi y'umuriro zo mu cyiciro cya B.

Byongeye kandi, inzugi z'umuriro zifite uduce twa mica zagaragaje imikorere myiza mu nkongi z'umuriro zibera mu isi. Mu nkongi y'umuriro y'inyubako y'amagorofa menshi muri Ositaraliya, inzugi z'umuriro zirimo uduce twa mica zatinze gukwirakwira kw'inkongi n'umwotsi, bituma abaturage babona umwanya wo kuva mu mutekano. Nyuma y'inkongi, byagaragaye ko izi nzugi zagumanye igice kinini cy'imiterere yazo, byafashije kugabanya ibyangiritse muri rusange by'inyubako.

Byongeye kandi, uduce twa mica twongera imbaraga za mekanike z'imizingi y'inzugi z'umuriro, bigabanya guhindagurika no kwangirika mu gihe cyo gushyiraho no gukoresha. Imiterere ifatanye igizwe n'uduce twa mica mu bikoresho by'ibanze ikora nk'umuyoboro w'imbaraga, itanga inkunga n'ubudahangarwa. Ibi ntibyongerera gusa ubushobozi bwo kwirinda inkongi y'umuriro ahubwo binatuma igihe cyo gukora cy'inzugi z'umuriro kirushaho kuba cyiza.

Ku bijyanye n'amarido y'umuriro—imigozi yoroshye ikoreshwa mu gufunga ahantu hashobora gushya mu nyubako z'ubucuruzi—udupira twa mica dushyirwa ku myenda idashobora gushya cyane nka fibre y'ikirahure cyangwa fibre ya aramid. Igitambaro cya mica (kirimo udupira twa mica 50%-60%) gikora nk'ubushyuhe, kigaragaza ubushyuhe bugera kuri 85% kandi kikarinda umwenda gushonga. Isoko rikuru ryo muri Esipanye ryashyizeho amarido y'umuriro yavuwe n'udupira twa mica tudashobora gushya: mu gihe cyo gupima umuriro, amarido yahagaritse gukwirakwira kw'umuriro mu gihe cy'iminota 80, atanga umwanya uhagije wo kwimura no guhagarika inkongi.

Byongeye kandi, ubushakashatsi bwagaragaje ko icyerekezo cy'udupira twa mica mu gipfundikizo gishobora kugira ingaruka zikomeye ku mikorere y'udupira tw'umuriro. Iyo udupira twa mica duhuye neza mu gihe cyo gupfundikizo, dushobora gukora uruzitiro rwiza rwo kwirinda ubushyuhe n'inkongi z'umuriro. Itsinda ryacu ry'ubushakashatsi n'iterambere ryateguye uburyo bwihariye bwo gupfundikizo butuma udupira tw'umuriro tuba twinshi, bigatuma udupira twinshi tudashya.

Bitandukanye n'amakarito asanzwe akoreshwa mu muriro agabanuka nyuma yo gukoreshwa kenshi, amakarito ashingiye kuri mica aramba neza, agumana ubushobozi bwayo bwo kwirinda umuriro mu gihe cy'imyaka 10 ariko nta kuyitaho cyane. Ubu buzima burambye butuma amakarito akoreshwa muri mica aba igisubizo gihendutse ku nyubako z'ubucuruzi, bigabanya gukenera gusimburwa kenshi n'amafaranga ajyanye no kuyasana.

Mu bikoresho byo gukingira inkuta, uduce twa mica dushyirwa mu bikoresho byo gukingira inkuta bishingiye kuri gypsum cyangwa sima kugira ngo twongere ubushyuhe n'ubudahangarwa bw'inkongi. Kongeramo 15%-25% bya uduce twa mica ku duce two gukingira inkongi twa gypsum bigabanya ubushyuhe kuva kuri 0.17 W/(m·K) kugera kuri 0.12 W/(m·K), bikongera ubushobozi bwo gukoresha ingufu ku kigero cya 25%-30%. Muri icyo gihe, ubudahangarwa bw'inkongi bw'inkongi bw'inkongi bwiyongereye cyane—ntibucana cyangwa ngo burekure umwotsi w'uburozi iyo bushyizwe mu muriro ufunguye, byujuje amahame akomeye y'umutekano w'inkongi y'Umuryango w'Ubumwe bw'u Burayi (EN 13501-1) na Leta Zunze Ubumwe za Amerika (ASTM E84).

Uretse kunoza ubushobozi bwo kwirinda inkongi no gukingira ubushyuhe, uduce twa mica tunagira uruhare mu mikorere y’amajwi y’uduce twa mica. Imiterere ya mica idafite aho ihuriye n’amajwi ifasha mu gukurura no kugabanya urusaku, bigagabanya urusaku hagati y’ibyumba. Ibi bituma uduce twa mica dukoresha insulation tuba amahitamo meza ku nyubako aho insulation idafite amajwi ari yo ishyirwa imbere, nko mu mahoteli, amashuri n’ibitaro.

Umushinga w’inyubako zo guturamo mu Budage wakoresheje izi paneli zo gukingira zifashishwa mica: inyubako zageze ku gipimo cyiza cya BREEAM mu gukoresha ingufu neza, kandi ibizamini by’umutekano mu nkongi byemeje ko izi paneli zagize uruhare mu kugabanya ibyago byo gukwirakwira kw’inkongi ku kigero cya 40% ugereranije n’izisanzwe zo gukingira. Intsinzi y’uyu mushinga yatumye abantu benshi bashishikazwa no gukingira izi paneli zo gukingira zifashishwa mica mu Burayi, aho abakora imishinga myinshi n’abayikorera bagaragaje ko ari bo bazikoresha mu mishinga yabo.

Udupira twacu twa mica tudashya tuboneka mu byiciro bibiri: udupira twa muscovite mica tudashya cyane (dufite ubushyuhe bugera kuri 750°C) n'udupira twa phlogopite mica dufite ubushyuhe buhanitse cyane (dufite ubushyuhe bugera kuri 1200°C). Ibipimo by'ingenzi bya tekiniki birimo: ubushuhe ≤0.3%, ivu ≤0.5%, ubwiyongere bw'ubushyuhe ≤0.08 W/(m·K), n'igipimo cyo kudashya (UL94) V-0. Ibicuruzwa byose bikorerwa isuzuma rikomeye, harimo isuzuma ry'ubushyuhe (mu itanura rifunguye), isuzuma ry'umuriro (rikoresheje kalorimetero y'ibuye), n'isuzuma ry'imyuka ihumanya (hakurikijwe ISO 19702), kugenzura ko amategeko agenga umutekano w'inkongi yubahirizwa ku isi.

Kugira ngo twizere ko imiterere n'ubuziranenge bya mica flakes zacu bihoraho, twashyizeho uburyo buhamye bwo kugenzura ubuziranenge muri buri cyiciro cy'umusaruro. Kuva ku gushakisha ibikoresho fatizo kugeza ku gupakira kwa nyuma, buri gice cya mica flakes kirasuzumwa neza kandi kigapimwa.

Dutanga ubufasha bwihariye ku bakora ibikoresho by'ubwubatsi. Ku bakora inzugi z'umuriro, turasaba gukoresha uduce twa phlogopite mica flakes mu gukoresha ubushyuhe bwinshi kandi tugafasha mu kunoza ikigereranyo cyo kuvanga kugira ngo tungane n'umuriro n'ikiguzi. Ku bikoresho byo kwambara imyenda y'umuriro, dutanga uduce twa mica flakes twa mikroni (ingano y'uduce 10-20 μm) dukora irangi ryoroshye kandi ringana ritagira ingaruka ku bukonje bw'imyenda. Itsinda ryacu rya tekiniki rinatanga amahugurwa aho bakorera ku bijyanye no gukwirakwiza uduce twa mica flakes, rigenzura ko ibikoresho bikwirakwira neza kugira ngo hirindwe ahantu hadakomeye mu bukonje.

Uretse ubufasha bwa tekiniki, tunatanga serivisi zo guteza imbere ibicuruzwa byihariye. Niba abakiriya bafite ibisabwa byihariye ku miterere ya mica flake, nko gukwirakwiza ingano y'uduce, gutunganya ubuso, cyangwa ibara, itsinda ryacu ry’ubushakashatsi n’iterambere rishobora gukorana nabo bya hafi kugira ngo bategure igisubizo cyihariye. Ubu buryo bworoshye butuma duhura n’ibyo abakiriya bacu bakeneye mu nganda z’ibikoresho by’ubwubatsi bakeneye.

Mu bijyanye n'ibikoresho, dukoresha ipaki ifunze neza kandi idashyuha (25 kg/umufuka) kugira ngo wirinde ko uduce twa mica twakwinjiriramo ubushuhe, ibyo bikaba byagabanya imikorere yabyo idashya. Dufatanya n'ibigo by'ubwikorezi byihariye mu bikoresho by'ubwubatsi, tukageza ibicuruzwa i Burayi, muri Amerika ya Ruguru, no mu Burasirazuba bwo Hagati mu minsi 20-35.
