    • System and method for production of membrane having high strength, enhanced thermal stability and chemical resistance comprising of at least two furnace plates, at least one heating coils encased in ceramic disc housing, metal sheet and base. Perforated ceramic discs of the invention are mounted on a movable stand and equipped with heating mantle, insulation and is encased in a metallic cover. The pores present on ceramic disc not only helps in dissipation of gases emanating from heating of wet metal oxide gel diaphragms but also conducts the heat from heating coil to it. The pores in the ceramic disc plays dual role i.e. exit of trapped water and other organic matter as well as entry of heat towards the wet gel films for faster drying. On the other hand the perforated ceramic disc has a major role to play in preventing the deformation likely to occur during sintering of semidried metal oxide gel diaphragms by putting a vertical pressure and controlling its morphology as the heating progresses towards high temperature in controlled manner. By means of this setup the semidried gel diaphragms are calcined at high temperatures to get the desired flawless plain porous ceramic membranes and all operations are done smoothly.
    • 用于制造具有高强度,增强的热稳定性和耐化学性的膜的系统和方法,包括至少两个炉板,至少一个加热线圈,其包裹在陶瓷盘壳体,金属片和基座中。 本发明的穿孔陶瓷盘安装在可移动的支架上,并配有加热套,绝缘层,并被封装在金属盖中。 陶瓷盘上存在的孔不仅有助于散发从湿金属氧化物凝胶膜片加热产生的气体,而且还将加热线圈的热量传导到其上。 陶瓷盘中的孔具有双重作用,即捕获的水和其它有机物质的出口以及向湿凝胶膜进入热量以加速干燥。 另一方面,穿孔陶瓷盘在防止半干式金属氧化物凝胶膜片烧结过程中出现的变形中起主要作用,通过放置垂直压力并控制其形态,随着加热以受控的方式朝向高温进行。 通过该设置,半干凝胶膜在高温下煅烧,得到所需的无瑕疵的普通多孔陶瓷膜,所有操作都顺利进行。
