Bubble amount.In sintering process, due to oxygen deficiency when silicon carbide foams, carbon monoxide may be will produce.Carbon monoxide has also
Originality can restore the colorants powder such as spinelle in green body, glaze or ink, weaken the color development of colorant, ink etc., influence color
The usage amount of material etc..Carbon monoxide and manganese dioxide generate redox reaction, and Oxidation of Carbon Monoxide becomes carbon dioxide, to
Carbon monoxide reduction is inhibited, and generates the gas needed for more foaming, does not influence the amount of application of colorant；
5, the sand, mud and mountain flour that multiple places of production are contained in the raw material of foaming layer, can not only reduce production cost, may be used also
To reduce the firing temperature of green body, steady production；
6, aging and feed bin is old using stock tank in the preparation method of the composite foamed entire body dalle of once-firing multi-density
Rotten process aging twice, can not only be such that the organic matter in green body material fully decomposes, and reduce organic matter in sintering process to base
The influence of body can also improve the uniformity of moisture in green body material, convenient for molding.
