I-Henan Sinmat Chemical Co., Ltd. yenye yezona zinto zithembekileyo eziveliswayo kunye nabanikezeli bohlobo lwe-b silica gel e-China. Ngamava amaninzi, siyakwamkela ngokufudumeleyo ukuba uthenge ijeli ye-silica ekumgangatho ophezulu ethengiswa apha kumzi-mveliso wethu. Qhagamshelana nathi ngesampuli yasimahla.
Intshayelelo
Uhlobo lwe-B lwe-silica gel okanye i-silica gel B, i-amorphous, i-adsorbent esebenzayo kakhulu yezinto eziphathekayo kunye nokusabalalisa ubungakanani bepore. Ubungakanani bayo bepore buphakathi kohlobo lwejeli ye-silica kunye nohlobo lwejeli ye-silica engu-C, enobungakanani bepore obumalunga ne-4~7 nm, oluphawu lwejeli ye-silica e-mesoporous. Umbindi-we pore ye-silica gel B iphunyezwa ngolawulo oluthile lobushushu obugugayo kunye nobude.
Uhlobo lwe-B ijeli ye-silica inezinga lokufunxa elicothayo kunye nomthamo ophantsi wokufunxa xa kuthelekiswa nohlobo lwejeli ye-silica ephantsi kweemeko zokufuma okuphantsi. Ifanelene ngakumbi nemekobume yokufuma okuphezulu ngenxa yomthamo wayo owomeleleyo we-adsorption, kwaye inegunya lokufuma{1}}lokulawula.
Uhlobo B ijeli ye-silica isetyenziswa ikakhulu ukugcina ukufuma-izinto ezinobuzaza (iintsalela zenkcubeko, oovimba, ifenitshala, izixhobo, iimbewu, njl.njl.), okanye njengepakethe ye-desiccant yokutya kunye namayeza, kunye nezinto zokuthwala iziqholo kunye nezinto zokuvuselela. Ijeli yodidi lwe-B ye-silica yijeli eguquguqukayo efunxa ukufuma kunye nokusebenza okulinganayo ngokubanzi, ilungele uninzi lweemeko zokufuma eziqhelekileyo -nobungqina, kwaye inezicelo ezininzi kwimizi-mveliso kunye neendawo zokupakisha.
