Abstract

PURPOSE:The captioned strainer of improved strength at high temperature by using synthetic layer-form minerals as the covering material for the strainer core material. CONSTITUTION:The covering C composed of the synthetic mica 1 mixed with inorganic binders 2 is formed to the strainer core material (b) made of glass cloth having multiple coarse mesh holes (a). If desired, it is possible to use a net made of metal as well, as the strainer core material. A dipping method is desirable for forming the covering on the strainer core material (b). The synthetic layer form minerals in this constitution comprise synthetic minerals such as synthetic mica as basic type and those in whose interlayer ions are substituted by other alkali metals or alkaline earth metals are contained therein. It is also possible to use the synthetic layer-form minerals by substituting part thereof with other refractory fine powders, e.g., Al2O3, ZrO2, MgO, etc.
