Ishobora Gutembanwa mu buryo bwa Refractory
Ibisobanuro by'igicuruzwa
Ibikoresho byo gukanda birekuyeni uruvange rw'ibintu birwanya imyuka, ifu n'ibindi bifunga. Nyuma yo kongeramo amazi cyangwa ibindi bintu bivangwa, birakwiriye mu bwubatsi hakoreshejwe uburyo bwo gusuka no guhindagura. Bishobora kandi gutegurwa mu bice byateguwe bifite imiterere n'ingano byagenwe byo kubaka imiyoboro y'amatanura yo mu nganda. Kugira ngo hongerwe imiterere ifatika n'iya chimique n'imikorere y'ubwubatsi bw'ibikoresho birwanya imyuka, akenshi hongerwamo ibintu bivangwa, nka plasticizers, dispersants, accelerators, retarders, expansion agents, debonding-gelling agents, nibindi. Byongeye kandi, ku bikoresho birwanya imyuka bikoreshwa ahantu hari imbaraga nyinshi za mekanike cyangwa shock ikomeye y'ubushyuhe, iyo hongewemo ingano ikwiye ya fibre ya stainless steel, gukomera kw'ibikoresho biziyongera cyane. Mu bikoresho birwanya imyuka, iyo hongewemo fibre inorganic, ntibishobora kongera ubukomere gusa, ahubwo binafasha mu kunoza imiterere yabyo yo gukingira ubushyuhe. Kubera ko imiterere y'ibanze y'ibikoresho bikoreshwa mu gukaraba (nk'ibiteranyo n'ifu, ibivange, ibifunga n'ibivange), uburyo bwo gufunga no gukomera, uburyo bwo kubaka, n'ibindi, bisa na beto mu ikoranabuhanga rya sivili, yigeze kwitwabeto ikora nk'ingufu.
