Kimwe mu bitandukanya cyane hagati y’uruvange rw’ibintu byumye n’uruvange rusanzwe ni uko uruvange rw’ibintu byumye ruhindurwa hakoreshejwe inyongera nke z’ibinyabutabire. Kongeramo ubwoko bumwe bw’inyongera ku ruvange rw’ibintu byumye byitwa ihinduka ry’ibanze, kongeramo inyongera ebyiri cyangwa nyinshi ni ihinduka ry’inyongera. Ubwiza bwa ruvange rw’ibintu byumye buterwa n’ihitamo ryiza ry’ibice n’imikoranire n’ibice bitandukanye. Inyongera z’ibintu by’imiti zirahenze kandi zigira ingaruka zikomeye ku miterere ya ruvange rw’ibintu byumye. Kubwibyo, mu guhitamo inyongera, ingano y’inyongera igomba kuba iya mbere. Ibi bikurikira ni incamake y’ihitamo ry’inyongera z’ibinyabutabire za cellulose ether.
Cellulose ether izwi kandi nka rheological modifier ubwoko bw'imvange ikoreshwa mu guhindura imiterere ya rheological ya mortilage nshya ivanze, hafi ya yose ikoreshwa muri mortilage yose. Imiterere ikurikira igomba kwitabwaho mu guhitamo ubwoko n'ingano y'inyongera:
(1) Kubika amazi mu bushyuhe butandukanye;
(2) ubunini, ubushyuhe;
(3) Isano iri hagati y’ubushyuhe n’ihindagurika ry’ikirere, n’ingaruka ku bushyuhe bw’ikirere iyo hari electrolyte;
(4) imiterere n'urwego rwa etherification;
(5) kunoza ubushobozi bwa thixotropy no gushyira ibintu mu mwanya wa morti (ibi bikaba ari ngombwa kugira ngo morti ipfundikwe ku buso buhagaze);
(6) Igipimo cy'iseswa, imiterere n'uko iseswa ryuzuye.
Uretse kongeramo eteri ya selulosi muri mortila yumye (nk'iya methyl cellulose ether), ishobora no kongeramo eteri ya aside ya vinyl polyvinyl, ni ukuvuga impinduka ya kabiri. Ifata ry’ibintu mu mortila (simenti, gypsum) rishobora kwemeza imbaraga nyinshi zo gukanda, ariko rigira ingaruka nke ku mbaraga zo gukurura no gukomera kw’ipfundo. Eteri ya vinyl polyvinyl yubaka firime irabagirana mu mwobo w’amabuye ya sima, ikora mortila ishobora kwihanganira uburemere bwinshi bwo kwangirika, yongera ubushobozi bwo kudashira. Byagaragaye ko mu myitozo yo kongeramo ingano zitandukanye za eteri ya methyl cellulose na eteri ya vinyl polyvinyl muri mortila yumye, mortila yo gufatanya plate yoroshye, mortila yo gusigwa, mortila yo gusigwa, mortila yo gusigwa, mortila yo gusigwa ya beto irimo umwuka n’mortila yo gusuka hasi ishobora gutegurwa. Kuvanga byombi ntibishobora kongera ubwiza bwa mortila gusa, ahubwo binanongera cyane imikorere y’ubwubatsi.
Mu buryo bufatika, kugira ngo kunoze imikorere yuzuye, ni ngombwa gukoresha ibintu byinshi bivanze. Uburyo bwiza bwo guhuza igipimo cy’inyongera, urugero rw’ingano ikwiye, igipimo, bishobora kugira ingaruka zitandukanye mu kunoza imikorere ya morti, ariko ingaruka zayo zo guhindura morti iyo ikoreshejwe yonyine ni nke, rimwe na rimwe zigira ingaruka mbi, nko kongera fibre imwe, kongera uburyo bwo gufatana kwa morti, kugabanya urugero rwo gutandukanya amazi icyarimwe. Ariko, ikoreshwa ry’amazi ya morti ririyongera cyane kandi ribikwa mu gishanga, bigatuma imbaraga zo gukanda zigabanuka. Iyo hongeweho igikoresho cyo gukurura umwuka, urugero rwo gukanda rwa morti n’amazi bishobora kugabanuka cyane, ariko imbaraga zo gukanda za morti zizagabanuka bitewe n’utubuto twinshi. Kunoza sima y'amabuye kugira ngo ikore neza cyane, ariko wirinde kwangiza indi mitungo, imbaraga za sima y'amabuye, urwego rw'imiterere yayo kandi wuzuze ibisabwa mu buhanga n'amabwiriza agenga imiterere ya tekiniki, ariko kandi ntugakoreshe lime putty, urinda sima, kurengera ibidukikije, nibindi, bitewe no kugabanya amazi, ubukana, ububyimbirwe bw'amazi no gushyira pulasitiki mu mwuka, Ni ngombwa gufata ingamba zihamye zo guteza imbere no gukoresha ibintu bivanze.
