Embodiment Construction

[0026] In order to further describe the present invention, it is further described below in conjunction with embodiment.

[0027] Such as Figure 1-2 As shown, the present invention discloses a test device for simplifying the volume expansion rate of rubber, which includes a balance and a water tank 2, and the water tank 2 is located below the balance. The balance includes a balance body 11, a tray, and a hook. A partition 21 is arranged in the water tank 2. The partition 21 divides the water tank 2 into several sub-water tanks 22. The corresponding sub-water tanks 22 of the hook are arranged under the balance body 11. , the tray is arranged above the balance body 11.

[0028] In some embodiments: the tray includes a weighing tray 121 and a weight tray 122 . The hooks include weighing hooks 131 . The weighing tray 121 and the weight tray 122 are symmetrically arranged on the left end and the right end of the balance body 11 respectively. A weighing hook 131 is provided bel...

Abstract

The invention discloses a testing device capable of simplifying volume expansion rate of rubber. The testing device comprises a balance and a water tank, wherein the water tank is positioned below the balance; the balance consists of a balance body, a tray and hooks, partition plates are arranged in the water tank and divide the water tank into a plurality of sub water tank bodies, hooks are arranged below the balance body corresponding to the sub water tank bodies, and the tray is arranged above the balance body. The invention further discloses a method for testing the volume expansion rate of rubber by utilizing the testing device capable of simplifying volume expansion rate of rubber. The testing device and testing method have the advantages of being simple and convenient for testing procedures, simplified in testing equipment, and high in testing precision.

Description

technical field [0001] The invention relates to the technical field of expansion rate test, in particular to a test device and a test method for simplifying the volume expansion rate of rubber. Background technique [0002] At present, the volume expansion rate test of rubber needs to use a tray balance and a hydrostatic balance at the same time. The specific calculation method is: (1) First, weigh the mass m of the sample in a dry state on a tray balance 1 , and then test the mass m of the sample when immersed in water by hydrostatic balance 2 , according to F 浮 =ρ 液 wxya 排 = (m 1 -m 2 ) g to get the volume V of the sample 1 ; (2) After the sample is soaked in water for a period of time, the mass of the test sample m 3 , and then take out the sample, wipe the moisture on the surface, and weigh the mass m of the sample in the dry state on a tray balance 4 , again through the principle of Archimedes buoyancy, test the volume V of the sample at this time 2 , to obtain...
