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.
