I-Henan Sinmat Chemical Co., Ltd. yenye yezona zinto zithembekileyo zabakhiqizi kunye nabanikezeli bohlobo lwejeli ye-silica e-China. Ngamava amaninzi, siyakwamkela ngokufudumeleyo ukuba uthenge ijeli ye-silica ekumgangatho ophezulu ethengiswa apha kumzi-mveliso wethu. Qhagamshelana nathi ngesampuli yasimahla.
Intshayelelo
C uhlobo lwejeli yesilica okanye ijeli yesilica C, yi amorphous, imathiriyeli esebenzayo kakhulu ye adsorbent enesakhiwo esirhabaxa- se pore, kwaye ibonakala njengegranular emhlophe ebisi. I-silica gel C ine-avareji yobukhulu bepore ye-8-10 nm, eluhlobo lwe-mesoporous silica gel. Ijeli yodidi lwe-C ye-silica inosasazo oluthe ngqo lwepore, ebonisa ukusebenza okugqwesileyo phakathi-ukuya{6}i-adsorption ephezulu yokufuma kunye ne-adsorption yolwelo izicelo.
Inxalenye ephambili yohlobo lwe-C silica gel nayo i-silicon dioxide, equkethe amanzi e-crystalline. Ayinyibiliki emanzini nakwizinyibilikisi zendalo kwaye ayinayo{1}}ityhefu, ayinavumba, ukuxhathisa kwiiasidi ezinamandla (ngaphandle kwe-hydrofluoric acid), kunye nokumelana nobushushu obuphezulu (ukuya kuma-300 degree). Ngenxa yobukhulu bayo bepore, uhlobo lwejeli ye-silica ye-C inomthamo omkhulu wepore, isantya se-adsorption esikhawulezayo, kunye noxinzelelo olusezantsi lwe-capillary condensation, iyenza ilungele ngakumbi ukuthengisa iimolekyuli ezinkulu.
Isishwankathelo, chwetheza ijeli ye-silica ye-C igqwesile kwi-adsorption kwindawo yokufuma okuphezulu kunye nokubhengeza iimolekyuli ezinkulu zezinto eziphilayo. Ngokuyinhloko isetyenziselwa ukomisa umoya woshishino, okanye njenge-package ye-desiccant ekuhlanjululeni amayeza kunye nokwahlula, ukuhlukana kweekhemikhali, ukubuyiswa kwe-solvent, kunye nokunyangwa kwegesi ephezulu yokufuma njl.
