| This paper analysed the main material desulphurization gypsum, which blended three different types of foaming agents, the retarders, water-reducing agents so as to develop one kind of light quality heat wall material.Through the unceasingly optimized adjustment of allocated proportion of raw material ,the goal is to make a shallow analyses and discussion on each kind of influencing factor on the change of the newly mixing-hydromass or hardened body,in order to provide some important referenceing on the following research in the desulphurization building gypsum material industrily using in the cast-in-place craft . This paper also analysed the scanning electron microscope observation on the desulphurization gypsum hardening body which use the foaming agent , from a microscopic angle further proving the foaming agent has affected the hole structure of the desulphurization gypsum. Macroscopically performancing the change of intensity and thermal conductivity .The retarder can adjust the setting time of the newly mixing- hydromass . The water- reducing agent may enable the hydromass to have big fluid at the same time obtaining a higher intensity.the using of foaming agent can not only enable the desulphurization gypsum to have a good hot working performance, but also remarkably improve the workability of hydromass, maintaining the shui gao bi in a invariable situation.The result indicated that the system which contained the alkyl sulonic acid sodium had the biggest degree of foaming power, next was the rosin , the system which contained alkyl oxide had the least degree of foaming power;On the setting time of Desulphurization building gypsum, Sodium tripolyphosphate had the most efficiency;The result also indicated that the system which contained Sodium tripolyphosphate,Gathers the carboxylic acid water reducing agent and Alkyl sulfonic acid sodium had the best performances.The study represented that the heat conduction performance and the mechanical properties of Desulphurization building gypsum hardening body not only have relation with the foaming agent, but also concern with the pole structure. |
