1. Ibintu byiza
(1) Inkunga ya politiki
Nka bio-ishingiye kubintu bishya hamwe nicyatsi kandi cyangiza ibidukikije, uburyo bwagutse bwoselile ethermurwego rwinganda ninzira yiterambere yo kubaka ibidukikije bitangiza ibidukikije kandi bizigama umutungo mugihe kizaza. Iterambere ry’inganda rijyanye n’intego y’igihugu cyanjye yo kugera ku iterambere rirambye ry’ubukungu. Guverinoma y'Ubushinwa yagiye itanga politiki n'ingamba nka “Gahunda yo Guteza Imbere Ubumenyi n'Ikoranabuhanga mu gihe kirekire (2006-2020)” na “Inganda zubaka“ Gahunda ya cumi na kabiri y'imyaka itanu ”Gahunda y'iterambere” kugira ngo ishyigikire inganda za selile.
Nk’uko byatangajwe na “2014-2019 Ubushinwa Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Report Prospect Analysis Report” bwashyizwe ahagaragara n’urusobe rw’amakuru y’inganda mu Bushinwa, iki gihugu cyashyizeho kandi amahame akomeye yo kurengera ibidukikije, ibyo bikaba byibanze ku bibazo byo kurengera ibidukikije ku buryo bushya urwego. Ibihano binini ku ihumana ry’ibidukikije byagize uruhare runini mu gukemura ibibazo nk’irushanwa ridahwitse mu nganda za selulose ether no guhuza ubushobozi bw’inganda.
(2) Ibyiringiro byo kumurongo wo hasi biragutse kandi ibyifuzo biriyongera
Cellulose ether izwi nka "inganda monosodium glutamate" kandi irashobora gukoreshwa mubice bitandukanye byubukungu bwigihugu. Iterambere ryubukungu byanze bikunze rizamura iterambere ryinganda za selile. Hamwe n’iterambere ry’iterambere ry’imijyi y’igihugu cyanjye hamwe n’ishoramari rikomeye rya guverinoma mu mutungo utimukanwa ndetse n’amazu ahendutse, inganda z’ubwubatsi n’ubwubatsi zizongera cyane icyifuzo cya selile. Mu rwego rw'ubuvuzi n'ibiribwa, imyumvire y'abantu ku buzima no kurengera ibidukikije iragenda yiyongera. Physiologique itagira ingaruka kandi idahumanya selile ya ether nka HPMC izagenda isimbuza buhoro buhoro ibindi bikoresho bihari kandi bitere imbere byihuse. Byongeye kandi, ikoreshwa rya selile ya selile mu gutwikira, ububumbyi, kwisiga, uruhu, impapuro, reberi, imiti ya buri munsi n’inganda zigenda ziyongera.
(3) Iterambere ry'ikoranabuhanga ritera iterambere ry'inganda
Mubyiciro byambere byiterambere ryinganda za selile yigihugu cyanjye, ionic carboxymethyl selulose ether (CMC) nicyo gicuruzwa nyamukuru. Hamwe nogukora ionic selulose ether ihagarariwe na PAC hamwe na ether ionic selulose ether ihagarariwe na HPMC Hamwe niterambere no gukura mubikorwa, umurima wo gukoresha selile ya selile waguwe. Ikoranabuhanga rishya nibicuruzwa bishya bizasimbuza byihuse ibicuruzwa gakondo bya selile ya ether kera kandi biteze imbere iterambere ryinganda.
2. Impamvu zitari nziza
(1) Irushanwa ridahwitse ku isoko
Ugereranije nindi mishinga yimiti, igihe cyo kubaka umushinga wa selulose ether ni mugufi kandi nibicuruzwa bikoreshwa cyane, kuburyo hariho ikibazo cyo kwaguka nabi muruganda. Byongeye kandi, kubera kutagira amahame yinganda n’amahame y’isoko yashyizweho na leta, hari ibigo bito bito bifite urwego ruto rwa tekiniki ndetse n’ishoramari rito mu nganda; bamwe muribo bafite ibibazo byangiza ibidukikije kuburyo butandukanye mubikorwa byumusaruro, kandi bagakoresha ubuziranenge, Igiciro gito nigiciro gito cyazanywe nishoramari rike ryo kurengera ibidukikije ryagize ingaruka kumasoko ya selile ya ether, bigatuma habaho ihiganwa ridahwitse kumasoko. . Nyuma yo kwinjiza ikoranabuhanga rishya nibicuruzwa bishya, uburyo bwo kurandura isoko buzamura imiterere ihari yo guhatanira imidugararo.
(2) Ubuhanga buhanitse kandi bwongerewe agaciro ibicuruzwa bigenzurwa n’amahanga
Inganda za selile zo mu mahanga zatangiye kare, kandi inganda zitanga umusaruro zihagarariwe na Dow Chemical na Hercules Group muri Amerika ziri ku mwanya wa mbere rwose mu bijyanye n’umusaruro n’ikoranabuhanga. Bibujijwe n'ikoranabuhanga, amasosiyete yo mu bwoko bwa selulose yo mu gihugu akora cyane cyane ibicuruzwa byongerewe agaciro gake hamwe n'inzira zoroheje zoroheje kandi ugereranije no kuba ibicuruzwa bitanduye, mu gihe amasosiyete yo mu mahanga yihariye isoko ry’ibicuruzwa byongerewe agaciro bya selile yifashishije inyungu z’ikoranabuhanga; Kubwibyo, Mu isoko rya selile yo mu gihugu imbere, ibicuruzwa byo mu rwego rwo hejuru bigomba gutumizwa mu mahanga kandi ibicuruzwa byo mu rwego rwo hasi bifite inzira zo kohereza ibicuruzwa hanze. Nubwo ubushobozi bwo gukora inganda zo mu bwoko bwa selulose ether bwiyongereye vuba, guhangana kwayo ku isoko mpuzamahanga birakomeye. Hamwe niterambere ryinganda za selulose ether, inyungu yinyungu yibicuruzwa byongerewe agaciro bizakomeza kugabanuka, kandi ibigo byimbere mu gihugu bigomba gushakisha iterambere ryikoranabuhanga kugirango biveho monopole yibigo byamahanga mumasoko yo murwego rwohejuru.
(3) Imihindagurikire y'ibiciro fatizo
Ipamba itunganijwe, ibikoresho nyamukuru byaselile ether, ni umusaruro w'ubuhinzi. Bitewe nimpinduka mubidukikije, umusaruro nigiciro bizahinduka, bizazana ingorane mugutegura ibikoresho fatizo no kugenzura ibiciro byinganda zo hasi.
Byongeye kandi, ibikomoka kuri peteroli nka okiside ya propylene na methyl chloride na byo ni ibikoresho by’ibanze byo gukora ether ya selile, kandi ibiciro byayo bigira ingaruka cyane ku ihindagurika ry’isoko rya peteroli. Imihindagurikire y’ibihe bya politiki mpuzamahanga akenshi igira ingaruka ku biciro bya peteroli, bityo rero uruganda rukora etherulose rukeneye guhangana n’ingaruka mbi z’imihindagurikire y’ibiciro bya peteroli ku musaruro n’imikorere.
