Ikoti rya Skim ni iki?

Ikoti rya skim ni igicucu cyibikoresho byashyizwe kurukuta cyangwa hejuru kugirango bikosore ubusembwa kandi bigire ubuso bunini bwo gushushanya cyangwa gushushanya. Ibikoresho bikoreshwa mugutwikisha skim mubusanzwe ni uruvange rwamazi, sima, nibindi byongerwaho nka selile ya ether.

Cellulose ether ni polymer-eruber polymer ikomoka kuri selile naturel. Ikoreshwa cyane mubikorwa byubwubatsi nkibibyimbye, stabilisateur, binder, hamwe nogukoresha amazi. Kubijyanye na skim coat, selulose ether yongewe kumvange kugirango itange imikorere myiza hamwe nuburyo bwo gufata amazi.

Imwe mu nshingano zingenzi za selile ether muri skim ikoti nubushobozi bwayo bwo kubyimba imvange. Ikoti ya skim igomba kuba yoroheje bihagije kugirango ikwirakwize hejuru hejuru ariko ikabyimbye bihagije kugirango yuzuze icyuho cyose cyangwa ubusembwa. Cellulose ether ifasha mukugera kumurongo ukwiye mubyimbye bivanze, byoroshye gukwirakwira neza hejuru.

Ikindi gikorwa cyingenzi cya selulose ether muri skim coat nubushobozi bwayo bwo kugumana amazi. Ikoti rya skim rigomba kuguma rifite igihe runaka mugihe runaka kugirango ryemeze neza kandi ririnde gucika cyangwa kugabanuka. Ether ya selile ifasha mukugumana amazi muruvange, itinda inzira yo kumisha kandi ikemeza ko ikoti rya skim ryashizweho neza.

Cellulose ether nayo ikora nka binder mu ikoti rya skim, ifasha guhuza imvange hamwe no kunoza imiterere yayo hejuru. Ibi byemeza ko ikote rya skim rigira umurunga ukomeye hamwe nubuso, bikarema neza ndetse nubuso bwo gushushanya cyangwa gushushanya.

Ubwiza n'imikorere ya skim ikoti byatewe cyane nubwoko nubunini bwa selile ya ether yakoreshejwe. Hariho ubwoko butandukanye bwa selile ether iboneka kumasoko, nka hydroxyethyl selulose (HEC), methyl selulose (MC), na carboxymethyl selulose (CMC). Buri bwoko bugira imiterere itandukanye nibiranga, kandi guhitamo ubwoko bukwiye nubunini nibyingenzi muguhitamo ubwiza bwikoti rya skim.

Muri make, selulose ether igira uruhare runini mugukora ikoti rya skim. Itanga ibyangombwa nkenerwa byo kubyimba, guhambira, hamwe no kubika amazi kubivangavanze, byemeza imikorere yabyo, bigahindura neza, kandi bikarinda gucika cyangwa kugabanuka. Guhitamo ubwoko bukwiye nubunini bwa selulose ether nibyingenzi mugukora ikote ryiza cyane ryujuje ubuziranenge bwujuje ubuziranenge bwinganda zubaka.
