Description

TECHNICAL FIELD

[0001] The utility model relates to water absorption detection technical field, more exactly relates to water absorption detection equipment for self -insulation block. BACKGROUND

[0002] Water absorption is a basic performance index of self -insulation block, if the water absorption of self -insulation block is too high, can lead to internal moisture increase, thermal conductivity increase, durability deterioration etc. Problem, and then influence its thermal insulation performance and strength, lead to the thermal insulation effect and structural strength of building to drop.

[0003] The water absorption of the existing self -insulation block is detected generally by being completely immersed in water, keeping for a period of time, then taking out and wiping the surface moisture with water absorption paper or cloth, then measuring the mass change of the brick, and calculating the water absorption according to the change, this method is simple and easy to operate, but the detection accuracy is not high, the interference of the moisture content of the self -insulation block before immersion is not eliminated, and it is only suitable for preliminary detection, and needs to be improved. UTILITY MODEL CONTENT

[0004] The utility model discloses a kind of water absorption detection equipment for self -insulation block, reduce the interference of the moisture content of the brick before immersion, make measurement more accurate, it is convenient to more accurately understand product water absorption performance.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] Water absorption detection equipment for self -insulation block, including heating cabinet and cabinet door, the inside bottom of the heating cabinet is installed with weighing tray, and the sidewall of the heating cabinet is inlaid with electric heating wire.

[0007] Further, the weighing tray is provided with multiple groups.

[0008] Further, the heating cabinet is provided with ventilation hole.

[0009] Further, the inside top of the heating cabinet is provided with electric heating lamp, and the outside top of the heating cabinet is installed with electric telescopic rod for driving the electric heating lamp to lift.

[0010] Further, the heating cabinet is installed with temperature sensor, the cabinet door is installed with control display panel, and the weighing tray, electric heating wire, electric heating lamp, electric telescopic rod and temperature sensor are electrically connected with the control display panel.

[0011] Compared with prior art, the utility model has the beneficial effects:

[0012] The brick to be detected is placed on the weighing tray, heated by the electric heating wire, the moisture on the brick is dried, then the brick is immersed in water for a period of time, and then the excess moisture on the surface of the brick is wiped dry, placed on the weighing tray, and dried again by heating, the change in mass of the brick before and after the second drying is measured by the weighing tray, and the water absorption rate of the brick is calculated, which can reduce the interference of the moisture content of the brick before immersion, make the measurement more accurate, and facilitate more accurate understanding of the water absorption performance of the product.
