Ibiryo byumye bishyirwa mu byiciro bibiri: bidafatana n'ibikomeye. Ibintu bidafatana byoroshye gutera zumye, imiterere yoroheje y'umuti wo kohereza kandi ifu ya nyuma itembera neza. Ingero z'ibikoresho bidafatana zirimo ifu y'igi, ifu y'amata, ibisubizo n'izindi maltodextrin, ishinya na poroteyine. Ku bijyanye n'ibiryo bifashe, hari ikibazo cyo kuma mu gihe cy'uburyo busanzwe bwo kuma. Ibiryo bifashena akenshi biguma ku rukuta rw'umuti wo kohereza, cyangwa bikaba ibiryo bifashena bitagira umumaro mu byumba byuma no mu buryo bwo gutwara, hamwe n'ibibazo bike mu mikorere n'umusaruro w'ibicuruzwa. Ingero zisanzwe z'ibiryo by'isukari na aside.

Viscos ni ikintu kigaragara mu buryo bwo kumisha ibiryo bikungahaye kuri aside glycolic. Viscos y'ifu ni ubwoko bw'imikorere yo gufatana. Ishobora gusobanura viscos y'uduce duto n'uduce duto (guhuza) n'iy'urukuta rw'uduce duto (guhuza). Igipimo cy'imbaraga zo gufatana n'uduce duto tw'ifu giterwa n'imiterere yabyo y'imbere yitwa cohesion, ikora ibintu byinshi mu gisenge cy'ifu. Kubwibyo, imbaraga zigomba guca mu gice cy'ifu zigomba kuba nini kuruta cohesion. Gufatana ni imikorere yo guhuza, kandi uduce duto tw'ifu dukurikiza icyerekezo cy'ibikoresho byo kumisha. Gufatana no gufatana ni ibipimo by'ingenzi mu gushushanya imiterere yo kumisha no kumisha. Imiterere y'ubuso bw'uduce duto tw'ifu ni yo ahanini ituma ibintu bikomera. Gufatana no gufatana kw'uduce duto tw'ifu biratandukanye. Kubera ko kumisha bisaba ingano nini y'umunyu kugira ngo wimurwe ku buso bw'uduce duto, ni mu bwinshi. Imiterere ibiri y'umunyu (gufatanya no gufatana) ishobora kuba hamwe mu bikoresho by'ibiribwa bikungahaye ku isukari ikoreshwa mu guterana. Viscos y'uduce ni ukurema ibiraro by'amazi bidahinduka, ibiraro by'amazi bigenda, iminyururu ya mekanike hagati y'uduce, n'uburemere bw'amashanyarazi n'ibiraro bikomeye. Impamvu nyamukuru ituma uduce tw’ifu yo ku rukuta dufatana mu cyumba cyo kumisha ni ukubura kw’ibikoresho mu isukari yumisha ikoreshwa mu gusukura no mu biribwa bikungahaye kuri aside. Iyo ifu ibitswe igihe kirekire, izumira ku rukuta.

Bijyana ku gucurama

SIkoranabuhanga ryo kumisha ifu yumisha ibiryo ikungahaye ku busabe bwo kongera gukoresha ifu yumisha. Isukari nkeya iragoye cyane (glucose, fructose) na aside organic (aside citric, aside malic, aside tartaric). Ibintu bito bya molekile nko kwinjiza amazi menshi, ubushyuhe bukabije n'ubushyuhe buke bwo guhindura vitrification (Tg) bigira uruhare mu bibazo by'ubushyuhe. Ubushyuhe bwo kumisha ifu buruta Tg20°C. Ibyinshi muri ibi bice bikora uduce tworoshye ku buso butose, bigatera ubushyuhe bw'ifu, amaherezo bigahinduka ifu. Ubushobozi bwinshi bwo kugenda kw'iyi molekile buterwa n'ubushyuhe bwayo bwo guhindura vitrification (Tg), bigatera ibibazo by'ubushyuhe mu byuma byumisha amavuta bikunze kumenyekana mu bushyuhe. Ibiranga ubushyuhe bw'ikirahure n'ubushyuhe bwo guhindura icyiciro kidahinduka. Impinduka y'ikirahure yabaye mu isukari ikomeye, idahinduka, yahindutse icyiciro cy'amazi yoroshye ya rubber. Ingufu zo hejuru n'ikirahure gikomeye bifite ingufu nke ku buso kandi ntibifata ku buso buto budafite ingufu nke. Bitewe n'imiterere y'ikirahure n'ifi ya rubber (cyangwa amazi), ubuso bw'ibikoresho bushobora kuzamurwa, kandi imikoranire hagati ya molekile n'ubuso buto bushobora gutangira. Mu bikorwa byo kumisha ibiribwa, ibicuruzwa biba biri mu imiterere y'amazi cyangwa kole, kandi ibiryo by'amazi/kole bikuraho pulasitiki (amazi) biba ikirahure. Niba ibikoresho fatizo by'ibiribwa bidahindutse kuva ku bushyuhe bwinshi bwo kumisha kuruta ubushyuhe bw'ikirahure, ibicuruzwa bizakomeza kuba bito cyane. Niba ubwoko bw'ibiryo bukozweho n'ubuso buto bukoresha ingufu nyinshi, buzabufata cyangwa bugafata.

Kugenzura ubukana bw'umubiri 

Hari ubumenyi bwinshi bw'ibikoresho n'uburyo bushingiye ku mikorere kugira ngo bigabanye ubushyuhe. Uburyo bw'ibanze bw'ubumenyi bw'ibikoresho burimo ibikoresho bifite ibirungo byinshi byo kumisha amazi kugira ngo byongere ubushyuhe bwo guhindura ubushyuhe hanze y'ingufu, naho uburyo bushingiye ku mikorere burimo inkuta n'ubuso bw'icyumba cy'imashini.
