3/ h(25 DEG C of water at low temperature) carry out heat exchange, to take away the heat in tread-rubber sheet.Along with the sweltering heat of weather, the raising of production efficiency, must must extend tank, strengthen the internal circulating load of water at low temperature to meet technological requirement.Just need to change after water simultaneously in tank uses January approximately continuously, due to the rubber of this water long period of soaking high temperature, some organic compounds in rubber are useful to be gone out to pollute water, and this water can not continue to use, must periodic exhaustion process.
Tank soaks cooling and there is following shortcoming: the main variations in temperature by WATER AS FLOW MEDIUM of cooling is to take away heat, and cooling rate is slow, and water demand is large, cause power consumption large, need periodic exhaustion sewage, factory building to take up an area large etc. shortcoming.
In order to adapt to the development of rubber for tire processing industry, the cool-down method of energy-conserving and environment-protective and technology are the directions of development.So the research of this respect, test, innovation must go out new results.
Summary of the invention
