Nk'uburyo bwo kuvanga bukora neza, eteri ya cellulose yo mu rwego rwo hejuru ishobora kunoza uburyo ibikoresho by'ubwubatsi bigumana amazi kandi bigakomera, kandi ikanoza ubushobozi bwo gukora. Ikoreshwa cyane mu kunoza no kunoza harimo sima y'amabuye, sima y'ubushyuhe, sima y'amatafari, sima yigenga, ndetse n'imikorere y'ibikoresho by'ubwubatsi birimo gukora resin ya PVC, irangi rya latex, putty idakira amazi, nibindi, bituma ihura n'ibisabwa mu kuzigama ingufu no kurengera ibidukikije, kunoza imikorere y'ubwubatsi n'imitako, kandi ikoreshwa mu buryo butaziguye mu mishinga itandukanye y'ubwubatsi. Kubaka ubutare n'ubusitani, imitako y'imbere n'inyuma y'inkuta bihuye n'icyerekezo cy'iterambere rya politiki y'igihugu y'inganda ku kuzigama ingufu no kurengera ibidukikije ibikoresho bishya by'ubwubatsi. Eteri ya cellulose yo mu rwego rwo hejuru y'ibikoresho by'ubwubatsi yo mu rwego rwo hejuru ya HPMC, kandi imirima yayo y'ingenzi irimo sima y'ubushyuhe, kole y'amatafari, kole yigenga, kole y'urukuta n'indi mirima y'imyuka ivanze, ndetse na polyvinyl chloride (PVC), slurry ya elegitoroniki n'indi mirima; Hari kandi n'ibindi bicuruzwa bisanzwe, bikoreshwa cyane cyane mu ibumba ryateguwe kuvanga, ibumba risanzwe na putty yo gukata inkuta.
Bitewe n'ishoramari rinini mu bijyanye n'ubwubatsi, isoko rinini ndetse n'ubukene bwinshi, ubukene rusange bw'ibikoresho byo kubaka bya eteri ya cellulose yo mu rwego rwa grade d'instruction ni bwinshi cyane kurusha ubukene bwa eteri ya cellulose yo mu zindi nzego. Ikoreshwa cyane cyane mu bikoresho bya mortier, bonding agent, PVC, putty, n'ibindi. Muri iki gihe, ubukene bw'igihugu cyanjye bwa eteri ya cellulose yo mu rwego rwa grade d'instruction (harimo ubwubatsi, PVC n'amabara yo gusiga) bungana na 90% by'ubukene bwa eteri ya cellulose yo mu rwego rwa grade d'instruction.
Ariko ukurikije uko isi ibibona, hafi 52% bya eteri za cellulose zitari ionic zikoreshwa mu bijyanye n'ibikoresho by'ubwubatsi, ibyo bikaba biri munsi cyane y'urwego rw'imbere mu gihugu. Impamvu nyamukuru ni uko, ku ruhande rumwe, igipimo cy'ishoramari mu bijyanye n'ubwubatsi mu gihugu cyanjye ari kinini kandi kigenda gikura. Nubwo umuvuduko w'iterambere ugenda ugabanuka, ingano ni nini; Kubwibyo, eteri ya cellulose yo mu rwego rw'ibikoresho by'ubwubatsi mu gihugu cyanjye ifite imiterere y'uburyo bwinshi bwo kuyikoresha, isoko rinini rikenewe, n'abakiriya batatanye. Hashingiwe kuri toni 220.000 za eteri ya cellulose yo mu rwego rw'ibikoresho by'ubwubatsi yasabwaga ku isoko ry'imbere mu gihugu mu 2018 n'igiciro mpuzandengo cya yuan 25.000 kuri toni, ingano y'isoko rya eteri ya cellulose yo mu rwego rw'ibikoresho by'ubwubatsi mu gihugu ni miliyari 5.5 z'amayuan.
Ku bijyanye na ether ya cellulose idafite ionic yo mu rwego rw'ibikoresho by'ubwubatsi, hari ibintu bibiri biranga. Mbere na mbere, igirwaho ingaruka cyane n'inganda ziri inyuma y'amazi nk'ubwubatsi, ubucuruzi bw'amazu n'imitako. Mu myaka ya vuba aha, nubwo ishoramari ry'ubutaka n'ubwubatsi mu gihugu cyanjye mu bigo biteza imbere ubucuruzi bw'amazu byariyongereye buri mwaka, igipimo cy'ubwiyongere cyaragabanutse cyane. Mu buryo nk'ubwo, igipimo cy'ubwiyongere bw'umusaruro w'ibirungo n'amabara byavanzwe ku rwego rw'igihugu cyaragabanutse.
Ikindi kintu kigaragara ni uko iyi politiki iyobora iterambere ry’inyubako zirinda ibidukikije, zibungabunga ingufu kandi zitangiza ibidukikije ndetse no kohereza icyifuzo cy’abakiriya mu Bushinwa mu mahanga, ibi bigabanya ingaruka zo kugabanuka k’ubwiyongere bw’ubutaka mu gihugu. “Gahunda ya cumi n’itatu y’imyaka itanu yo kubungabunga ingufu no guteza imbere inyubako zirinda ibidukikije” ishyira imbere intego. Mu 2020, urwego rw’ingufu z’inyubako nshya zo mu mijyi ruziyongeraho 20% ugereranije no mu 2015; igipimo cy’ubuso bw’inyubako zirinda ibidukikije mu nyubako nshya zo mu mijyi kizarenga 50%, naho igipimo cy’ibikoresho by’ubwubatsi birinda ibidukikije bizakoreshwa birenga 40%; ubuso bwo kuvugurura inyubako zisanzwe zirinda ibidukikije burenga metero kare miliyoni 500, naho kuvugurura inyubako za leta zirinda ibidukikije bungana na metero kare miliyoni 100. Igipimo cy’inyubako zirinda amashanyarazi mu nyubako zisanzwe zo mu mijyi n’imijyi hirya no hino mu gihugu kirenga 60%. Iterambere rya cellulose ether ritanga inkunga ya politiki. Nyuma y’ikibazo cy’imyenda mu Burayi mu 2012, abakiriya bo mu bihugu bimwe na bimwe bongereye ibyo baguraga mu Bushinwa no mu bindi bihugu biri mu nzira y’amajyambere kugira ngo bahangane n’icyo kibazo kandi bagabanye ikiguzi.
