Abstract

A disclosed hot-air ageing test box for rubber comprises a box body, a box door and a controller at one side of the box body, and is characterized in that the box body inside comprises a test chamber, the exterior of the test chamber is coated by a heat-insulation layer, and the test chamber and the heat-insulation layer are provided with communicated air holes; a hot-air channel is arranged between the heat-insulation layer and the box body, positions, at two sides of the heat-insulation layer, of the hot-air channel are both provided with a heating pipe, and one end, opposite to the heating pipe, in the hot-air pipe is provided with a blower fan; the medial-axis position in the test chamber is provided with two rotary shafts; the periphery of each rotary shaft is uniformly provided with a group of rubber clamping plates, and each rubber clamping plate is provided with a clamping part; and the rotary shafts are connected an motor. The hot-air ageing test box for rubber is uniform in ageing temperature and capable of precisely realizing heat treatment of a stretched sample band.

Description

technical field [0001] The invention belongs to the technical field of rubber detection equipment, and in particular relates to a rubber hot air aging test chamber. Background technique [0002] Existing aging test chambers for materials such as rubber, plastics, PVC, etc., have a structure comprising a casing with an insulating layer, an air inlet arranged on the side wall of the casing, and a A fan sent into the box from the air inlet, a heating pipe that can heat the air entering the box to the temperature of the aging test, and a turntable installed in the box driven by a motor through a mechanical transmission mechanism. The method of using this aging test box First, put the material to be tested on the turntable, and then start the fan and motor; at this time, the outside air enters the box from the air inlet, and is heated by the heating tube to reach the temperature required for the material aging test; at the same time, the turntable Through the slow rotation of th...
