Gel wofiira wa silika
Chogulitsachi chili ndi tinthu tozungulira kapena tosakhazikika. Chimawoneka ngati chofiirira chofiira kapena lalanje chofiira chokhala ndi chinyezi. Kapangidwe kake kakakulu ndi silicon dioxide ndipo mtundu wake umasintha ndi chinyezi chosiyana. Kupatulapo mawonekedwe ngati abuluusilika gel, ilibe cobalt chloride ndipo siili ndi poizoni, siivulaza.

Alumino silica gel–AN
Mawonekedwe a aluminiyamusilika gelNdi yachikasu pang'ono kapena yoyera yowonekera bwino yokhala ndi formula ya molekyulu ya mankhwala mSiO2 • nAl2O3.xH2O. Makhalidwe okhazikika a mankhwala. Osayaka, osasungunuka mu chosungunulira chilichonse kupatula maziko olimba ndi hydrofluoric acid. Poyerekeza ndi silica gel yosalala yokhala ndi porous, mphamvu ya adsorption ya chinyezi chochepa ndi yofanana (monga RH = 10%, RH = 20%), koma mphamvu ya adsorption ya chinyezi chambiri (monga RH = 80%, RH = 90%) ndi yokwera ndi 6-10% kuposa ya silica gel yosalala yokhala ndi porous, ndipo kukhazikika kwa kutentha (350℃) ndi 150 ℃ kuposa silica gel yosalala yokhala ndi porous. Chifukwa chake ndi yoyenera kugwiritsidwa ntchito ngati chosinthira kutentha kwa adsorption ndi separation agent.

Gel ya silica ya Alumino - AW
Izi ndi mtundu wa aluminiyamu wofewa komanso wothira madzisilika gelKawirikawiri imagwiritsidwa ntchito ngati gawo loteteza la silica gel yosalala yokhala ndi pobowola pang'ono komanso aluminiyamu silica gel yosalala yokhala ndi pobowola pang'ono. Ingagwiritsidwe ntchito yokha ngati madzi aulere ali ndi madzi ambiri. Ngati makina ogwiritsira ntchito ali ndi madzi amadzimadzi, mame ochepa amatha kupezeka ndi mankhwalawa.

Chikwama chaching'ono cha desiccant
Silica gel desiccant ndi mtundu wa zinthu zopanda fungo, zokometsera, zopanda poizoni, zomwe zimayamwa kwambiri komanso zimatha kulowetsedwa bwino. Ili ndi mphamvu yokhazikika ya mankhwala ndipo sichitapo kanthu ndi zinthu zina kupatula Alkai ndi Hydrofluoric acid, zomwe ndi zotetezeka kugwiritsidwa ntchito ndi zakudya ndi mankhwala. Silica gel descicant imachotsa chinyezi kuti ipange mpweya wouma kuti usungidwe bwino. Matumba a silica gel awa amabwera mumitundu yosiyanasiyana kuyambira 1g mpaka 1000g - kuti ikupatseni magwiridwe antchito abwino kwambiri.

Gel Woyera wa Silika
Silica gel desiccant ndi chinthu chogwira ntchito kwambiri cholowetsa madzi, chomwe nthawi zambiri chimakonzedwa pophatikiza sodium silicate ndi sulfuric acid, ukalamba, acid bubble ndi njira zingapo pambuyo pa chithandizo. Silica gel ndi chinthu chosasinthika, ndipo njira yake ya mankhwala ndi mSiO2. nH2O. Sisungunuka m'madzi ndi zosungunulira zilizonse, sizowopsa komanso zopanda kukoma, zokhala ndi mankhwala okhazikika, ndipo sizimayanjana ndi chinthu chilichonse kupatula maziko olimba ndi hydrofluoric acid. Kapangidwe ka mankhwala ndi kapangidwe ka thupi ka silica gel kumatsimikizira kuti ili ndi makhalidwe omwe zinthu zina zambiri zofanana zimakhala zovuta kuzisintha. Silica gel desiccant ili ndi mphamvu yayikulu yolowetsa madzi, kukhazikika kwa kutentha, mphamvu yokhazikika ya mankhwala, mphamvu yayikulu yamakina, ndi zina zotero.

Gel ya Silika ya Buluu
Chogulitsachi chili ndi mphamvu yoletsa chinyezi komanso kusanyowa ngati silika gel yokhala ndi mabowo abwino, zomwe zimadziwika kuti ikayamba kuyamwa chinyezi, imatha kukhala yofiirira ndi kuwonjezeka kwa kuyamwa kwa chinyezi, ndipo pamapeto pake imakhala yofiira pang'ono. Sizingowonetsa chinyezi cha chilengedwe, komanso zimawonetsa ngati zikufunika kusinthidwa ndi desiccant yatsopano. Itha kugwiritsidwa ntchito yokha ngati desiccant, kapena ingagwiritsidwe ntchito limodzi ndi silika gel yokhala ndi mabowo abwino.
Gulu: chizindikiro cha guluu wabuluu, guluu wabuluu wosintha mtundu umagawidwa m'mitundu iwiri: tinthu tozungulira ndi tinthu ta block.

Gel ya Silika ya Orange
Kafukufuku ndi chitukuko cha mankhwalawa chachokera pa silika gel yabuluu yosintha mtundu, yomwe ndi silika gel yosintha mtundu wa lalanje yomwe imapezeka poika silika gel yokhala ndi mabowo abwino ndi chisakanizo cha mchere wosakanizidwa. Chogulitsachi chakhala mbadwo watsopano wa zinthu zosamalira chilengedwe zomwe zili ndi mikhalidwe yake yoyambirira yaukadaulo komanso magwiridwe antchito abwino oletsa kuzizira.
Chogulitsachi chimagwiritsidwa ntchito makamaka pa desiccant ndipo chimasonyeza kuchuluka kwa desiccant ndi chinyezi cha phukusi lotsekedwa, zida zolondola ndi zoyezera, komanso kukana chinyezi cha phukusi ndi zida zina zonse.
Kuwonjezera pa makhalidwe a guluu wabuluu, guluu wa lalanje ulinso ndi ubwino wosakhala ndi cobalt chloride, wosakhala ndi poizoni komanso wosavulaza. Pogwiritsa ntchito pamodzi, amagwiritsidwa ntchito kusonyeza kuchuluka kwa chinyezi chomwe chimayamwa mu desiccant, kuti adziwe chinyezi cha chilengedwe. Amagwiritsidwa ntchito kwambiri mu zida zolondola, mankhwala, petrochemical, chakudya, zovala, zikopa, zipangizo zapakhomo ndi mpweya wina wa mafakitale.
