Nigute ushobora gukora silika gel?

Silica gel ni ubwoko bwibikoresho bikora cyane.
Nibintu bya amorphous kandi formulaire yimiti ni mSiO2.nH2O. Yujuje ubushinwa bwa shimi HG / T2765-2005. Nibikoresho byangiza byemewe na FDA bishobora guhura neza nibiryo nibiyobyabwenge. Gelika ya Silica ifite ubushobozi bukomeye bwa hygroscopique, imikorere ikomeye ya adsorption, nubwo desiccant ya silika gel iba yuzuye mumazi, ntabwo yoroshye cyangwa ngo isukure. Ifite ibiranga uburozi, uburyohe, kutangirika no kutanduza, bityo birashobora guhura muburyo butaziguye nikintu icyo aricyo cyose. Ibikoresho fatizo bigomba gutegurwa kugirango habeho umusaruro wa silika ni: sodium silike (paucine, ikirahuri cyamazi), aside sulfurike.

Ubwa mbere, alkali na aside byateguwe hakiri kare, hanyuma silikatike ya sodium ikomeye irashonga ku bushyuhe bwinshi hanyuma ikayungurura kugirango hategurwe urugero runaka rwamazi, hanyuma aside sulfurike irategurwa kugeza kumurongo runaka wamazi, kwibumbira hamwe kwa sulfurique aside ni 20%.

Icya kabiri, intambwe ya kabiri nugukora kole (gel granulation), iyi ntambwe niyo ikomeye cyane, ibisubizo byateguwe mbere ya bubble lye hamwe na acide sulfurike ya acide mugihe cyihariye, kugirango bibe igisubizo cya gel gishonga, nyuma yo kugera kubitekerezo bikwiye guhinduka gel. Imiterere nubunini bwibice bishobora kugenwa rwose ukurikije ibyo ukoresha nubushobozi bwo gukora. Uburyo busanzwe bwa gel granulation ni granulation yo mu kirere, kandi igipimo cya aside-fatizo, igiteranyo, ubushyuhe hamwe nigihe cya granulation ikoreshwa muburyo bwa tekinoroji ya gel ni ibipimo byihariye byikoranabuhanga.

Icya gatatu, geli ishaje igomba kunyura mugihe runaka nubushyuhe, kimwe nagaciro ka PH kumyaka, bigatuma skeleton ya gel ikomera, korohereza kole hagati yibice mugihe cyo gusaza kugirango ube umubano wa Si-O-Si, utezimbere imbaraga za skeleton, ibice byegeranye, bigabanya umwanya muburyo bwa gride, namazi arimo arimo arasohoka.

Gutoragura, gukaraba, gukaraba kole Gutoragura, gukaraba, gukaraba kole nabyo ni intambwe ikomeye mubikorwa, kuko Na2SO4 yakozwe na gel granular yogejwe. Igenzura buri anion murwego rusabwa nibikorwa. Turashobora kuvuga ko igice kinini cyibintu biranga pore biranga gelika ya silika yarangiye bigenwa nubusaza bwibikorwa byo gukaraba, kandi gusaza kurwego rwibikorwa biterwa nigikorwa cyo gutoragura, gukaraba, no gukaraba.

Icya gatanu, kumisha, hydrogel yateguwe (nyuma yo gukaraba) mucyumba cyo kumisha, mubihe byihariye kugirango igabanye amazi ya gel ubwayo yumye kugeza kurwego rusabwa. Ubushyuhe bwo hejuru bwumutse, niko igipimo cyo guteranya ibice byibanze hamwe nubunini bwa aperture.

Gatandatu, kwerekana, imashini itoranya imipira izumishwa nyuma ya silicone binyuze muri ecran ya aperture zitandukanye ukurikije ingano nini yagenzuwe, kandi icyarimwe izavunika silika gel yerekanwe hanze.

Birindwi, gutoragura kole: gelika ya silika mumupira wa heterochromatique, umwanda uratora hanyuma ugakoresha impapuro zikomatanya ukurikije ibisabwa mubipfunyika, nyuma yo gufunga. Nyuma yintambwe yavuzwe haruguru, ibicuruzwa bya silicone birakorwa.
