Ifunze yerekeza ku gikoresho cyo gufunga gihinduka bitewe n'imiterere y'ubuso bwo gufunga, kidapfa gutemba neza, kandi gifite uburyo runaka bwo gufatana.
Ni kole ikoreshwa mu kuzuza icyuho cyo gufunga. Ifite inshingano zo kurwanya amazi, kudapfa amazi, kurwanya kuzungazunga, gukumira urusaku no kwirinda ubushyuhe. Ubusanzwe, ibikoresho byumye cyangwa bidashyushye nk'ibice by'ibanze bikoreshwa nk'ibikoresho by'ibanze, kandi hiyongereyeho ibintu bidafite imbaraga nka talc, ibumba, umukara wa karuboni, dioxyde de titanium na asbestos. Ikoreshwa mu gufunga, gushonga, imiti ivura, accelerators, nibindi. Ishobora kugabanywamo ibice bitatu: elastic sealant, liquid sealing gasket na sealing putty. Ikoreshwa cyane mu gufunga ubwubatsi, gutwara, ibikoresho by'ikoranabuhanga n'ibice byabyo.
Hari ubwoko bwinshi bw'ibifunga: Ibifunga bya silikoni, ibifunga bya polyurethane, ibifunga bya polysulfide, ibifunga bya acrylic, ibifunga bya anaerobic, ibifunga bya epoxy, ibifunga bya butyl, ibifunga bya neoprene, ibifunga bya PVC, n'ibifunga bya asphalt.
Imiterere y'ingenzi ya sealant
(1) Isura: Isura y'icyuma gifunga iterwa ahanini n'uko icyuma gifunga gikwirakwira mu gice cyo hasi. Icyuma gifunga ni ifu ikomeye. Nyuma yo gukwirakwira hakoreshejwe icyuma gisya, icyuma gisya n'imashini ikoresha imibumbe, gishobora gukwirakwira neza mu cyuma cyo hasi kugira ngo gikore ifu nziza. Uduce duto tw'uduce cyangwa umucanga ni ibintu bisanzwe kandi bizwi. Iyo icyuma gifunga kidakwirakwira neza, hagaragara uduce twinshi tw'udusimba. Uretse gukwirakwira kw'ibikoresho, hari n'ibindi bintu bigira ingaruka ku isura y'umusaruro, nko kuvanga imyanda y'uduce, gushwanyagurika, nibindi. Ibi bifatwa nk'ibikomeye mu isura.
(2) Ubukomere
(3) Imbaraga zo gukurura
(4) Uburebure
(5) Uburyo bwo gukurura no kwimura
(6) Gufata ku butaka
(7) Gusohora: Iyi ni imikorere y'iyubakwa ry'ibumba. Ikintu gikoreshwa mu kugaragaza ingorane z'ibumba iyo gikoreshejwe. Kole nini cyane ntishobora gusohora neza, kandi bizagorana cyane kuyishyiramo kole iyo ikoreshejwe. Ariko, niba kole yakozwe nto cyane ukurikije gusa ubushobozi bwo gusohora, bizagira ingaruka ku buhanga bwa thixotropy bw'ibumba. Ububasha bwo gusohora bushobora gupimwa hakoreshejwe uburyo bwavuzwe mu gipimo cy'igihugu.
(8) Thixotropy: Iki ni ikindi kintu cy’imikorere y’icyuma gifunga. Thixotropy ni ikinyuranyo cyo guhindagurika kw’amazi, bivuze ko icyuma gifunga gishobora guhindura imiterere yacyo gusa bitewe n’igitutu runaka, kandi gishobora kugumana imiterere yacyo iyo nta mbaraga zo hanze zihari. Igenwa ry’igabanuka ryagenwe n’amahame y’igihugu ni ugusuzuma thixotropy y’icyuma gifunga.
