Ni gute wakora gel ya silica?

Gel ya silica ni ubwoko bw'ibikoresho bikora cyane mu kunyuzamo amazi.
Ni ikintu kidahinduka kandi formula yacyo ya shimi ni mSiO2.nH2O. Yujuje ubuziranenge bwa shimi bw’Abashinwa bwa HG/T2765-2005. Ni ibikoresho fatizo bya desiccant byemewe na FDA bishobora gukorana n’ibiribwa n’imiti. Geli ya silica ifite ubushobozi bwo kuyungurura cyane, ubushobozi bwo kuyishyiramo neza, nubwo desiccant ya silica gel yaba yuzuye mu mazi, ntabwo yoroha cyangwa ngo ihinduke. Ifite imiterere yo kudahumanya, kudahindura uburyohe, kudahindura imiterere kandi kudahumanya, bityo ishobora gukorana n’ikintu icyo ari cyo cyose. Ibikoresho fatizo bigomba gutegurwa kugira ngo gel ya silica ikoreshwe ni: sodium silicate (paucine, ikirahuri cy’amazi), aside sulfure.

Ubwa mbere, alkali na aside bitegurwa mbere y'igihe, hanyuma sodium silicate ikomeye ishongeshwa ku bushyuhe bwinshi igashungurwa kugira ngo hategurwe urugero runaka rw'amazi, hanyuma aside sulfurike igategurwa ku rugero runaka rw'amazi, urugero rwa aside sulfurike ni 20%.

Icya kabiri, intambwe ya kabiri ni ugukora kole (gel granulation), iyi ntambwe ni yo y'ingenzi cyane, isukari ya bubble lye na aside sulfurike byakozwe mbere mu bihe runaka, kugira ngo habeho isukari ya gel ishongesha, nyuma yo kugera ku gipimo gikwiye hazahinduka uduce twa gel. Imiterere n'ingano y'uduce bishobora kugenwa neza hakurikijwe ibyo umukoresha akeneye n'ubushobozi bwe bwo gukora. Uburyo busanzwe bwo gucukura gel ni ugucukura umwuka, kandi igipimo cya aside-base, igipimo, ubushyuhe n'igihe cyo gucukura gel bikoreshwa mu gikorwa cyo gucukura gel ni ibipimo byihariye by'ikoranabuhanga.

Icya gatatu, jeli ishaje igomba kunyura mu gihe runaka n'ubushyuhe, ndetse n'agaciro ka PH ku gihe ishaje, bigatuma igishishwa cya jeli gikomera, kole iri hagati y'uduce mu gihe cyo gusaza igakora imigozi ya Si-O-Si, yongera imbaraga z'igishishwa, uduce tuba twegeranye, ikagabanya umwanya mu miterere y'urukuta, kandi amazi arimo agakurwamo.

Gusuka, gukaraba, gukaraba kole Gusuka, gukaraba, gukaraba kole nabyo ni intambwe y'ingenzi cyane muri iki gikorwa, kuko Na2SO4 ikorwa na gel y'ibice bito irasukurwa. Genzura buri anion iri mu rugero rusabwa n'iki gikorwa. Bishobora kuvugwa ko igice kinini cy'imirongo y'imashini ya silica irangiye igenwa n'uko imashini ishaje, kandi urwego rwo gusaza rw'iki gikorwa ruterwa n'imikorere mu gikorwa cyo gusuka, gukaraba, no gukaraba kole.

Icya gatanu, gukamisha, hydrogel yateguwe (nyuma yo gukaraba) mu cyumba cyo kumisha, mu bihe byihariye kugira ngo igabanye amazi ya gel ubwayo yumuke kugeza ku rugero rukenewe. Uko ubushyuhe bwo kumisha burushaho kuba bwinshi, ni ko umuvuduko w'ibice by'ibanze byo kwibumbira hamwe n'umwobo munini.

Imashini ipima umupira izamurwa nyuma yo gupima silicone binyuze mu mwenge utandukanye hakurikijwe ingano y'uduce runaka, kandi icyarimwe izacukurwaho gel ya silica yamenetse.

Icya karindwi, gukusanya kole: gel ya silica iri mu mupira wa heterochromatic, imyanda ikurwamo hanyuma ugakoresha impapuro zivanze hakurikijwe ibisabwa mu ipaki, nyuma yo gufunga. Nyuma y'intambwe zavuzwe haruguru, ibicuruzwa bya silica birakorwa.
