Glazing and sanding process of rod-shaped porcelain insulator

The invention relates to the technical field of rod-shaped porcelain insulator treatment, in particular to a glazing and sanding process of a rod-shaped porcelain insulator. The process comprises thefollowing steps of baking inspection, blank pretreatment, glazing and sanding wherein the glazing comprises the steps of preparing glaze slip, rotating the blank at a constant speed; stably submergingthe rotating blank into the glaze slip; stably lifting out the glazed blank to complete the glazing; the sanding comprises the steps of preparing sand adhering glue; determining a sanding part afterthe glazed blank is stably placed, and making a mark; rotating the blank at a constant speed; evenly smearing a layer of sand adhering glue on the sanding part where the mark is made; uniformly spraying a layer of sand grains after the sand adhering glue is smeared to form a sand surface; uniformly spraying a layer of sand-coated glaze on the sand surface so as to complete the sanding. The whole surface glaze layer of a sin
