Loss on ignition and the ignition loss of the meaning of the actual significance of desiccant, the initial focus is to control the water content of desiccant, molecular sieve, but also can ensure a relatively inert characteristics of desiccant, desiccant initial water content is too high, meaning that the desiccant It may have been excessive water absorption, then the dew point control desiccants greatly reduced, loading the initial dew point of this desiccant hollow glass will rise, which will reduce the life of the respective hollow glass; in addition, the loss on ignition too also may be another problem, Lishui molecular sieve is the desiccant may contain inorganic chloride or easily decomposed, such as nitrite, acids, bases or substance containing labile organic matter, so too the loss on ignition , there is too unstable chemical substances containing such substances is corrosive, Yongkang molecular sieves, seriously affecting the life of insulating glass, Wenling molecular sieves, before the first chapter has been analyzed. The pretreated zeolite is placed after the waste muffle calcined at 180 ℃ 2h, then allowed to warm to continue calcined at 500 ℃ 4h, to obtain a modified molecular sieve adsorbent waste. 1.2.2 Evaluation adsorption method (1) simulated water sample preparation method. Formulation containing Ca2 + standard solution of calcium chloride dihydrate (analytical). According to the experimental diluted to different needs of different concentrations. Zeolite | new molecular sieve | Yiwu new zeolite molecular sieves by the Shanghai Limited. Zeolite | new molecular sieve | Yiwu new zeolite molecular sieves are Shanghai Co., Ltd. (www.molsionms.com) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, for the latest information Contact: Mr. Pan.
