Ibikomoka kuri vitamine byose bikomoka ku ipamba cyangwa ku giti, bikorerwa binyuze mu gushonga. Ibikomoka kuri selulosi bitandukanye bikoresha ibintu bitandukanye bitanga ubushyuhe. Ikintu gitanga ubushyuhe gikoreshwa muri hydroxyethyl cellulose (HEC) ni ethylene oxide, naho ikintu gitanga ubushyuhe gikoreshwa muri hydroxypropyl methylcellulose (HPMC) ni ubundi bwoko bw'ibintu bitanga ubushyuhe. (chloromethane na propylene oxide).
Mu irangi rya szone nyaryo na latex, hydroxyethyl cellulose ishobora gukoreshwa nk'ingufu zo gukurura.
Irangi nyaryo ry'amabuye ryoroshye kuringiza kubera ubwinshi bwaryo hamwe n'uburyo rinini. Ni ngombwa kongeramo imashini igabanya ubukana bwaryo kugira ngo rihuze n'ubukana bukenewe mu gihe cyo kuritera, rirusheho kuguma neza mu bubiko, kandi rigere ku mbaraga runaka.
Niba ushaka ko irangi ry’amabuye nyaryo rigira imbaraga nziza, ridashobora kugwa mu mazi neza kandi ridashobora kugwa mu kirere, guhitamo ibikoresho fatizo n’igishushanyo mbonera cy’imvange ni ingenzi cyane.
Mu bihe bisanzwe, ingano ya emulsion ikoreshwa mu irangi ry’amabuye nyayo ryiza izaba iri hejuru ugereranyije.
Urugero, mu irangi ry’amabuye nyaryo, hashobora kuba hari ibiro 300 bya emulsion ya acrylic yonyine na ibiro 650 by’umucanga w’amabuye w’umwimerere. Iyo ingano ikomeye ya emulsion ari 50%, ingano ya kilogarama 300 za emulsion nyuma yo kumisha ni litiro 150, naho ingano ya kilogarama 650 z’umucanga ni litiro 228. Ni ukuvuga ko PVC (ingano y’ibara ry’amabara) y’irangi ry’amabuye nyaryo ni 60% muri iki gihe, kuko uduce tw’umucanga w’amabara ari tunini kandi tudahuje imiterere, kandi iyo habayeho ingano runaka y’uduce, irangi ry’amabuye ryumye rishobora kuba riri muri CPVC (ingano y’ubunini bw’ingenzi). Ingano y’ingano y’amabara) hafi. Ku bijyanye n’ingufu, niba uhisemo cellulose ifite ubukana bukwiye, irangi ry’amabuye nyaryo rishobora gukora firime yuzuye kandi yuzuye kugira ngo ihuze n’ibisabwa bitatu by’ingenzi by’irangi ry’amabuye nyaryo. Niba ingano y'irangi nyaryo ry'amabuye ari nke, ni byiza gukoresha selulose ifite ubukana bwinshi nk'ikintu gikomeza ubukana (nk'ubukana 100.000), cyane cyane nyuma y'uko igiciro cya selulose cyiyongereye, bishobora kugabanya ingano ya selulose ikoreshwa bigatuma ibuye nyaryo riba ibuye nyaryo. Imikorere y'irangi iba myiza kurushaho.
Bamwe mu bakora amarangi y’amabuye ahendutse bakoresha hydroxypropyl methylcellulose aho gukoresha hydroxyethyl cellulose kubera ikiguzi n’ibindi bintu.
Ugereranyije n'ubwoko bubiri bwa selulose, selulose ya hydroxyethyl ifite ubushobozi bwo kubika amazi neza, ntizatakaza amazi bitewe na gelatin ku bushyuhe bwinshi, kandi ifite ubushobozi bwo kurwanya indwara ya mildew. Kugira ngo urebe imikorere, ni byiza gukoresha selulose ya hydroxyethyl ifite ubukana bwa 100.000 nk'umuti wo gukurura irangi nyaryo ry'amabuye.
