Comprehensive integral testing equipment for density and thermal shock damage of ceramic

Abstract

The invention discloses comprehensive integral testing equipment for density and thermal shock damage of ceramics. A lower bottom plate of a frame is horizontally placed on a support base; a working platform surface is mounted inside the frame; support screw rods are mounted inside the frame; the frame is encircled by an outer baffle plate; a glass rotating door is arranged in the outer baffle plate; a cover is arranged at the upper part of a lifting basket; an iron block is embedded into the cover; a magnetic sucker is mounted at the front end of a cylinder; the cylinder is hung at the lower end of a rocker arm; the rocker arm is connected with a synchronous motor; heating cylinders are arranged right above auxiliary heaters and magnetic stirrers; the bottoms of cooling cylinders are arranged right above the magnetic stirrers; copper tubes are arranged on the circumferences of the cooling cylinders; the cooling cylinders contact the magnetic stirrings; temperature sensors are arranged inside the heating cylinders and the cooling cylinders; liquid level sensors are arranged inside the heating cylinders. By adopting the comprehensive integral testing equipment, conversion of testing of density and thermal shock can be achieved, testing requirements of different standards and different ceramic products can be met, precise control on temperature and movement can be achieved through the temperature sensors, the liquid level sensors and an industrial control computer, testing automation can be achieved, the workload of operators can be reduced, and testing influence can be reduced.

Description

Technical field

[0001] The invention relates to a testing machine for ceramic compactness and thermal shock damage, especially applicable to domestic and foreign related standards of various ceramics such as building ceramics, daily-use ceramics, sanitary ceramics, etc., while realizing compactness and thermal shock damage detection. Background technique

[0002] The compactness of ceramic products is a key indicator to measure its liquid adsorption and permeability; the ceramic thermal shock resistance index can effectively verify the thermal expansion coefficient difference between the phases of the porcelain body, the adaptability of the glaze, the mechanical strength and the degree of deformation And other performance pros and cons. At present, various testing institutions generally use simple devices such as kitchen steel pots or constant temperature water baths to test the compactness and thermal shock damage of sanitary ceramics. The entire testing process is completely ...
