Guca umucanga: Guca umucanga bikunze gukoreshwa mu nganda z'amavali bishobora kandi kugabanywamo ubwoko butandukanye bw'umucanga nkaumucanga utose, umucanga wumye, umucanga w'ibirahuri by'amazi n'umucanga wa furan resin udatekahakurikijwe uburyo butandukanye bwo gufunga.
(1) Umucanga w'icyatsi ni uburyo bwo gushushanya aho bentonite ikoreshwa nk'icyuma gifunga mu kazi. Ibiranga ni ibi: ibumba ry'umucanga rirangiye ntirigomba kumywa cyangwa ngo rikoreshwe mu buryo bwihariye bwo gukomera, ibumba ry'umucanga rifite imbaraga runaka zo gutose, kandi igice cy'umucanga n'igishishwa bifite ubushobozi bwo gusukura no kugwa kw'umucanga. Ubushobozi bwo gukora ibumba ni bwinshi, igihe cyo gukora ni gito, kandi ikiguzi cy'ibikoresho nacyo ni gito, byoroshye gutegura ikorwa ry'umurongo w'iteraniro. Ingaruka mbi zabyo ni izi: ibumba rikunze kugira inenge nk'imyenge, imicanga ivanze, n'umucanga ufatana, kandi ubwiza bw'ibumba, cyane cyane ubwiza bw'imbere, ntabwo buhagije.
(2) Umucanga wumye ni uburyo bwo gukora icyitegererezo hakoreshejwe ibumba nk'icyuma gifunga, kandi bentonite ntoya ishobora kongera imbaraga zayo z'ubutose. Ibiranga ni ibi: ifu y'umucanga igomba kumyuka, ifite umwuka mwiza wo kwinjira no gukwirakwira mu kirere, ntibyoroshye gutanga inenge nko gukaraba umucanga, gufata umucanga, n'imyenge, kandi ubwiza bw'imbere bw'icyuma nabwo ni bwiza. Ingaruka mbi ni izi: ibikoresho byo kumisha umucanga birakenewe, kandi ukwezi gukora ni kure.
(3) Umucanga wa sodium silicate ni uburyo bwo gushushanya hakoreshejwe ikirahuri cy'amazi nk'icyuma gifunga. Ibiranga ni ibi: ikirahuri cy'amazi gifite inshingano yo gukomera mu buryo bwikora nyuma yo guhura na CO2, kandi gishobora kugira ibyiza bitandukanye byo gushushanya imiterere yo gukomera kwa gaze no gukora igice cy'imbere. Ariko, hari ibibi nko kudakora neza kw'ibishishwa, kugorwa no gusukura umucanga ku bicukurwa, ndetse n'umuvuduko muto wo kongera gukoresha umucanga wakoreshejwe.
(4) Gutunganya umucanga wa Furan resin no-bake ni uburyo bwo gucukura hakoreshejwe furan resin nk'icyuma gifunga. Mu bushyuhe bw'icyumba, umucanga wo gucukura urakira bitewe n'uburyo igifunga kibikoramo hakoreshejwe uburyo bwo gucukura. Ibiranga ni ibi: ikimera cy'umucanga ntigikeneye kuma, bigabanya cyane ukwezi k'umusaruro kandi bikagabanya ingufu. Umucanga wo gucukura resin woroshye kuwutsindagira kandi ushobora gushonga neza, kandi umucanga wo gucukura w'ibice bicukura nawo ushobora gusukurwa byoroshye, imiterere y'ibice bicukura ni myinshi, kandi ubuso bumeze neza, bishobora kunoza cyane ubwiza bw'ibice bicukura. Ingaruka mbi zabyo ni izi: ubwiza bw'umucanga mubi nabwo buri hejuru, aho ukorerwa hari impumuro mbi gato, kandi igiciro cya resin nacyo kiri hejuru. Uburyo bwo kuvanga umucanga wo gucukura resin: Umucanga wo gucukura resin ubwawo ni byiza gukorwa n'umucanga ukomeza kuvanga, wongeramo umucanga mubi, resin, umuti, nibindi, hanyuma ukabivanga vuba. Vanga kandi ukoreshe igihe icyo ari cyo cyose. Uburyo bwo kongeramo ibikoresho fatizo bitandukanye mu kuvanga umucanga wa resin ni ubu bukurikira: umucanga w'umwimerere + umuti uvura (umuti w'amazi wa p-toluenesulfonic) – (120-180S) – resin + silane – (60-90S) – umucanga (5) Ubwoko busanzwe bw'umucanga Uburyo bwo gucukura: gucukura neza.
