查询词典 air time

This technique has two prominent problems: titanium"s burning loss and high temperature melt treatment (up 1873K). The author puts forward melting protective cover used by plant ash which can insulate air and enhance effect of heat preservation effectively. At the same time, the author chooses alkalinous magnesite for furnace lining which can avoid redox reaction between silicon oxide (SiO2) and titanium, improve fireproofness of furnace lining and decrease titanium"s burning loss ratio.

Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.
