Tester for compressive strength of hollow glass beads

Abstract

The invention discloses a tester for the compressive strength of hollow glass beads. The tester is formed by combining a pressurized part and a high pressure testing part, wherein the pressurized part consists of an air compressor (1), a compressed air control valve (3), a compressed air pressure gauge (4), a booster pump (5), a nitrogen cylinder (13), a nitrogen pressure gauge (12) and a nitrogen control valve (11); the high pressure testing part comprises high pressure chambers (7); the high pressure chambers (7) are arranged in an explosion-proof barrel; the high pressure chambers (7) consist of high-pressure hexagonal tanks, high-pressure hollow bolts, high-pressure bolts and sample chambers; the sample chambers consist of transparent glass tubes and micropore plugs; the high-pressure chambers (7) are connected with a pressure relief and air leakage device consisting of a pressure relief valve (9) and an air leakage safety cap (10); and the compressed air pressure gauge (4), a high-pressure nitrogen pressure gauge (6), the nitrogen pressure gauge (12), the compressed air control valve (3), the nitrogen control valve (11) and the pressure relief valve (9) are mounted on an operating instrument panel. The tester is simple in structure, accurate and convenient to operate, and visual and detailed in data display.

Description

technical field [0001] The invention relates to a particle strength measuring device, in particular to a measuring device for the compressive strength of hollow glass microspheres, which can be used for testing the strength of various hollow powder inorganic materials. Background technique [0002] Hollow glass microspheres are more and more widely used in many fields such as composite materials, paints, and oil exploration due to their small particle size, light weight, thermal insulation, small dielectric constant, and flame retardancy. [0003] It exhibits better performance than general inorganic materials, mainly due to its closed hollow structure. If the airtight hollow of the hollow glass microsphere is broken down by an external force, the excellent performance of the hollow glass microsphere will be lost. Therefore, the maximum pressure that the hollow glass microsphere can withstand when its internal hollow structure is broken down becomes one of the most importan...
