FNG耐水硅膠為白色或灰白色多微孔顆粒，主要成分為SiO2·nH2O，不溶于水和無(wú)機(jī)酸，溶于氫氟酸和濃苛性堿溶液，機(jī)械強(qiáng)度高。該產(chǎn)品是以通用硅膠為原料經(jīng)過(guò)進(jìn)一步加工制成的非均質(zhì)成形硅膠，它在具有普通均質(zhì)硅膠的孔隙結(jié)構(gòu)和吸附性能的同時(shí)還具有良好的耐水性，即在水中不炸裂，因而擴(kuò)大了硅膠的應(yīng)用領(lǐng)域。

FNG water-resistant silica gel is white or off-white multi-microporous particles, the main component is SiO2·nH2O,  Insoluble in water and inorganic acids, soluble in hydrofluoric acid and concentrated caustic soda solutions. High mechanical strength. The product is made of general silica gel as raw material after further processing of heterogeneous shaped silica gel, it has the pore structure and adsorption properties of ordinary homogeneous silica gel at the same time also has good water resistance, that is, it does not burst in water, thus expanding the application field of silica gel.

本品主要用于壓縮空氣的干燥凈化、空分行業(yè)用做乙炔、二氧化碳的吸附劑；工業(yè)催化劑載體；工業(yè)氣體的干燥、水質(zhì)凈化等方面。

The product is mainly used for the dry purification of compressed air, air separation industry used as acetylene, carbon dioxide adsorbent; Industrial catalyst carrier; Industrial gas drying, water purification and other aspects.
