Product Overview:

RJ-V5The concrete rapid freeze-thaw testing machine adopts the water freeze-thaw method, which meets the appearance requirements100*100*400The freeze-thaw resistance test of concrete specimens can be placed once5Group（16The piece contains a central specimen. During the experiment, the test piece is placed in a test rubber cylinder, which is filled with water. The rubber cylinder is then placed in a test piece box containing antifreeze, and the unit's cooling or heating of the antifreeze is used to freeze or melt the test piece in the rubber cylinder, thus completing the freeze-thaw test.

The device operates fully automatically throughout the entire process, without the need for human intervention. When the experiment is completed to the set point (default)50After a certain number of times, the machine will automatically stop and emit a prompt sound to indicate the completion of the test. If the test needs to continue, the set number of times can be accumulated and the machine will continue to run.

characteristic:

characteristic1The compressor has low power,3PImported compression refrigeration. Whether placed indoors or not Still outdoors, with low noise.

2Heating does not use heating tubes and has low power. The heating tube is soaked in antifreeze for a long time, which is prone to conductivity and other phenomena, affecting the heating life.

3Integrated machine, easy to move in the laboratory.

4environment protection Low noise and energy-saving. The body is compact and does not take up much space.

Experimental parameters:

Freeze thaw cycle period 2.5~4Hours, melting time not less than1/4Freeze thaw cycle, center temperature of the specimen at the end of freezing-18±2℃Melting, the center temperature of the specimen at the end of melting5±2℃Cooling time1.5-2.5Hour, heating time1.0-1.5Hour, the temperature difference between the center and surface of the specimen is less than28℃The standard for the number of cycles is300Multiple times.
