Description
Technical field
The utility model belongs to chemical industry detection technique field, is specifically related to a kind of device of measuring the foamed glass foaming temperature.
Background technology
Blowing temperature is a crucial controlling factor during foamglass is produced, and determines that blowing temperature is the gordian technique during foamglass is produced with holding water.Usually adopt orthogonal test and batch is done differential thermal analysis (DTA) (DTA) determine.Determine that with orthogonal test blowing temperature needs the experiment more than three times could determine blowing temperature, experimental period is long, and the raw material consumption is big; Adopt DTA to determine that the blowing temperature of foamglass once can only test a sample, experimental period is long, and must just can find out its blowing temperature according to relevant professional knowledge, and method of testing is not directly perceived.
Aspect the research of determining the foamed glass foaming temperature, adopt temperature gradient furnace to determine that the domestic Guo Hongwei of having only of blowing temperature of foamglass has done certain research to it, he puts into porcelain boat with batch, push then in the temperature gradient furnace that has heated up, after being incubated according to blowing temperature, take out rapidly the cooling back and under reading microscope, measure the size of its bubble diameter, and, find out blowing temperature in conjunction with the temperature gradient curve of thermal gradient furnace.Reported among the CN286435Y with thermal gradient furnace and come board design production to determine the blowing temperature of foamglass that this method can not be observed the behavior of foamglass in foaming process intuitively and change.And real process test specimen large usage quantity.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and measurement result is the foamed glass foaming temperature measuring apparatus accurately.
For achieving the above object, the technical solution adopted in the utility model is: comprise by furnace shell and be arranged on the tubular furnace that the insulation material in the furnace shell is made, in tubular furnace, be provided with the temperature-control heat couple that is connected with temperature controller, one side of tubular furnace is provided with the standard couple that is connected with potential difference meter, the both sides of tubular furnace also have been provided with the transparency silica glass plate of sealing process, and place the lower end of tubular furnace temperature-control heat couple in the transparent quartz glass tube of placing sample.
The combustion chamber of tubular furnace of the present utility model is with being provided with the corundum ceramic pipe, and is wound with platinum wire on corundum ceramic pipe outer wall; The lower end of transparent quartz glass tube also is provided with fire resistive material.
The utility model adopts tubular furnace to determine the blowing temperature of foamglass fast; By record and the volume of analytical sample and the blowing temperature that change of shape is determined foamglass; Not only simple in structure, easy to use, the result is accurate, and can help to formulate rational foamglass firing process system, instructs and produces, and has saved the time for production, has saved the energy.
