Urukuta ni iki

Urukuta rushyizweho ni ubwoko bwibikoresho bikoreshwa mu koroshya ubuso bwurukuta kuzuza icyuho no kuringaniza. Nifu ya sima ivanze namazi kugirango ikore paste imeze nkibishobora gukoreshwa kurukuta. Kimwe mu bintu byingenzi bigize urukuta ni selulose ether.

Cellulose ether ni polymer-eruber polymer ikomoka kuri selile naturel. Ikorwa no guhindura imiti ya selile, ni polymer isanzwe iboneka murukuta rw'ibimera. Ether ya selile ikoreshwa cyane mubikorwa byubwubatsi nkibibyimbye, stabilisateur, binder, hamwe nogukoresha amazi. Ikoreshwa kandi mu gukora ibicuruzwa bitandukanye byabaguzi, nkibiryo, amavuta yo kwisiga, hamwe n’imiti.

Kubireba urukuta rushyizweho, selile ether ikora nkibyimbye kandi bihuza. Iyo selulose ether yongewe kurukuta rwa putty ivanze, itezimbere imikorere yayo itanga umurongo uhamye. Ibi byoroshe gushira putty kurukuta kandi ikemeza ko ifashe neza hejuru. Ether ya selile nayo ifasha mukurinda kugabanuka no guturika kurukuta rumaze gukama.

Urundi ruhare rwingenzi rwa selile ya ether muri putty ni ubushobozi bwayo bwo kugumana amazi. Urukuta rugomba kuguma rufite igihe runaka mugihe runaka nyuma yo kubisaba kugirango rwume neza kandi rukora umurunga ukomeye hamwe nurukuta. Ether ya selile ifasha mukugumana amazi muruvange rwa putty, itinda inzira yo kumisha kandi ikemeza ko ibishishwa byashyizweho neza.

Ubwiza nibikorwa byurukuta rushyizweho cyane nubwoko nubunini bwa selile ether yakoreshejwe. Hariho ubwoko butandukanye bwa selile ether iboneka kumasoko, nka hydroxyethyl selulose (HEC), methyl selulose (MC), na carboxymethyl selulose (CMC). Buri bwoko bugira ibintu bitandukanye nibiranga, kandi guhitamo ubwoko bukwiye nubunini nibyingenzi muguhitamo ubwiza bwurukuta.

Muncamake, selile ether igira uruhare runini mukubyara inkuta. Itanga uburyo bukenewe bwo kubyimba, guhambira, no kubika amazi kumvange ya putty, ituma ikora neza, ikarinda kugabanuka no gucika, kandi ikanuma neza kandi igahuza hejuru yurukuta. Guhitamo ubwoko bukwiye nubunini bwa selulose ether nibyingenzi mugukora urukuta rwiza rwo hejuru rwujuje ubuziranenge bwifuzwa mubikorwa byubwubatsi.
