A heating tube in the heater, the calorimeter and the specimen holder are arranged on the both sides of the board insulation, and are parallel with the board insulation. The design of the board insulation is reasonable, the structure of the instrument and the measuring method are not easy to produce error, the measuring accuracy is high, and the data is accurate and visual.
Description
The utility model belongs to the instrument of measuring flame retardant textiles heat-insulating, fire-preventing performance, particularly a kind of fabric heat-radiating properties analyzer of being made up of heating furnace, thermal insulation board, sample holder, calorimeter, microcomputer automatic control, monitoring and data handling system, operation keyboard, display and support.
At present, comparatively advanced in the world fabric heat radiation testing tool is the TPP instrument of du pont company, and its heating tube horizontal parallel is arranged, sample places the thermal source top, like this, and at the trial except that heat radiation, also can produce heat conduction and thermal convection, thereby cause error, data are inaccurate.Its thermal insulation board is a monoblock type, thereby thermal radiation range is big, has increased test error.The calorimeter that the TPP instrument of du pont company adopts is tens grams only, and thermal capacitance is very little, differs greatly with the human body thermal capacitance, can not directly reflect the heat-proof quality of heat-barrier material to human body.
The purpose of this utility model is to provide a kind of improved vertical thing heat-radiating properties analyzer at the deficiencies in the prior art.Its thermal insulation board reasonable in design, heating, test mode are difficult for producing error, measuring accuracy height, data accurately, intuitively.
The purpose of this utility model is achieved through the following technical measures.
Constitute fabric heat-radiating properties analyzer by heating furnace, thermal insulation board, sample holder, calorimeter, microcomputer automatic control, monitoring and data handling system, operation keyboard, display and support.Be characterized in: thermal insulation board is a double-body bike, fixedly thermal insulation board is vertically mounted on the support, the centre has a hole, there is chute the top, hole, movable thermal insulation board is housed in the chute, active clapboard can slide along chute under the gear train of automatic controlling system drives, and opens or close the fixedly center pit of thermal insulation board.When heating furnace began to heat, fixedly the thermal insulation board center pit was closed, and heat can not be radiated on the sample.Be heated to test when temperature required, open center pit.Because center pit is less, the concentrated area helps to improve measuring accuracy to the sample radiation heat relatively.
Further technical measures of the present utility model are: for improving the effect of heat insulation of thermal insulation board, fixedly thermal insulation board and movable thermal insulation board are composited by multilayer material, it is the copper radiating tube of carrying chilled water that there is one deck the centre, and the copper radiating tube is connected with water pump by inlet pipeline.Calorimeter and sample holder all are contained on the same horizontal guide rail and slide, so that the distance of adjusting and heating furnace.Heating tube in calorimeter and sample holder and the heating furnace is in the both sides of thermal insulation board, and parallel with it.Like this, can reduce the error that causes owing to heat conduction and thermal convection during test.According to the thermal capacitance of tissue, the calorimeter thermal capacitance is 500～600J, has filled the high silica fiber of good heat-insulation effect around it, can make test data accurate, and is directly perceived.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to accompanying drawing, there is a horizontal guide rail (2) on the left side above the main frame support (1), and calorimeter (3) and sample holder (4) place on the guide rail (2) and can slide, and what support (1) was gone up the right is heating furnace (9), and heating furnace (9) thermal source adopts Globar.What install in the middle of the support (1) is fixedly thermal insulation board (8) and movable thermal insulation board (7) thereof, fixedly thermal insulation board (8) and movable thermal insulation board (7) are by the fine copper plate, the copper radiating tube, high silica fiber heat-insulation layer and stainless steel protective shield are composited for four layers, fine copper plate face is near radiation source, fixedly the square hole of the length of side 50～70mm is left in thermal insulation board (8) center, there is a chute top in hole, movable thermal insulation board (7) is housed in the chute, movable thermal insulation board (7) can be up and down under the gear train (6) of automatic controlling system drives, to close or to open fixedly thermal insulation board (8) center square hole.Two thermal insulation boards (7,8) are connected with chilled water when test, heat radiation can be cut off effectively.Reach at thermal source under the situation of testing setup temperature, apart from thermal insulation board (7, the 8) back side of thermal source 6cm, temperature rise is no more than 2 ℃.
During use, earlier computer power is opened, opened display power supply again, microsystem begins self check, and as no abnormal, display shows the test master menu, activates with Genius mouse to start button, does test and prepares.
Connect the backup system power supply, the water circulating pump running, air compressor machine starts, water proper flow to be recycled, tensimeter is indicated greater than behind the 0.1MPa, could connect host power supply, otherwise answer shutdown inspection.
Connect host power supply, furnace temperature is transferred to temperature required, as 815 ℃.Take off calorimeter (3), sample (5) is fixed on calorimeter (3) front end with sample folder (4), then, calorimeter (3) and sample (5) are placed on the horizontal guide rail (2), adjust the distance of it and thermal insulation board (7,8).Observe heating furnace (9) temperature control display (11), stove to be heated (9) temperature rise is to the temperature that sets, and with the detection dish collection of mouse activation test menu, beginning detects automatically.
During test, movable thermal insulation board (7) is opened fixedly thermal insulation board (8) center square hole automatically, and thermal source will be radiated on the sample (5), and pass to calorimeter (3), and when waiting to heat up greater than 10 ℃, movable thermal insulation board (7) can be closed fixedly thermal insulation board (8) center square hole automatically.After 5 minutes, microcomputer begins deal with data, and the result is presented on the screen.Can draw hot transmission factor HTI and correlation parameter.
