Chinhu chikuru chakagadzirwa nealumina desiccant ivhu remhando yepamusoro realuminium hydroxide, iro riri rudzi rwe oxide yekutanga ine mvura inosvika 3-5%, uye kupiswa kwealumina hydroxide pa900-1100℃ i34.5%.
Maitiro ekugadzira activated alumina desiccant ndeaya anotevera:
Aluminium hydroxide – kuomesa – chigayo kusvika pa600 mesh, aluminum hydroxide 300 ℃ nekukurumidza kupera mvura mumuviri – kuumba madhisiki – kurapwa kwekubatidza muviri kwemaawa gumi nemaviri – kuburikidza neshaft kiln 550 ℃ sintering.
1. Upfu hwearuminiyamu hydroxide hweindasitiri, hune hunyoro hwe3-5%, hunoomeswa pa120℃ nemidziyo mikuru yekuomesa.
2. Mushure mekuomeswa, upfu hwearuminiyamu hydroxide hunopinda mukugaya kukuru uye hunopwanywa kusvika pamameshes mazana matanhatu. Kana hutete hwacho hwakanyanya kunaka, hunonyanya kunaka kuti hugadzirwe kuita bhora. Zvidimbu zvakaumbwa hazvina upfu uye zvine simba guru.
3, upfu hwearuminiyamu hydroxide, hunopinda musystem yekubvisa gasification nekukurumidza kuti itange kupiswa, upfu hwakatsetseka hwearuminiyamu hydroxide mumhepo inopisa ine mhepo inoyerera zvakanyanya hunogara 0.10s, musimboti wekugadzira ndewekuti: aruminiyamu hydroxide nekukangwa nekukurumidza, uye kutonhora nekukurumidza.
4, uchishandisa musimboti webhora rechando, kugadzirwa kwebhora reactivated alumina, maitiro aya anogona kugadzirwa nedhayamita dzakasiyana dzeactivated alumina desiccant uye carrier.
5, bhora rezvimedu zvealumina zvakashanda rinomira kwemaawa gumi nemaviri, kupisa kwaro nemvura kuti zvishande.
6. Pakupedzisira, alumina inoshandiswa inopiswa muchoto chakamira, uye tembiricha yekugocha ndeye 550-700℃.
