Several methods for inspecting quality of glass bricks

Number of visits: Date:2013-09-25 16:54

Inspection of glass plates: as for appearance quality, mainly inspect flatness and observe whether there are bubbles, sundries, scratches, drawing lines, and fog spots. Glass with such defects may deform, and glass’ transparency, mechanical strength, and heat stability may reduce, so that they are not appropriated to be used in engineering. Glass is transparent object, so that quality can be basically identified through visual inspection.

Inspection of glass processing products: they shall be inspected according to requirements of plate glass, and it is necessary to inspect their processing quality and to detect whether specification and dimension are standard and whether machining accuracy and patterns’ definition meet requirements or not. And at the same time, fragments are not allowed.

There shall not be cracks on appearance of hollow glass bricks, without non-transparent objects in gobs and bad welding and cementing between two glass bodies. Through visual inspection, there shall not be layered stripes generated by non-uniform materials in gobs. Internal hollow on outside surface of glass bricks shall be less than 1mm, while outset of glass bricks shall be less than 2mm, whose weight shall meet quality standards, without such quality defects as warping, gap, and blur, and their angle shall be square.

Hollow glass bricks have such advantages as transmitting, thermal insulation, sound insulation, and moisture proof, which are most appropriately used in places with weak lights. With convenient construction of glass bricks, walls of two sides can be completed for one construction. As for supporting materials, only cement is needed.
