Abstract
The utility model provides a remain charcoal layer strength test device after burning of toper calorimeter sample, including spherical briquetting, on the slider of following vertical slip setting was fixed in to the upper end of spherical briquetting, the upper end of spherical briquetting was provided with the forced induction piece. In order solving on current phase, there is not the problem of corresponding effectual intensity measurement device to adding behind the fire retardant the fine material of glass. The utility model belongs to the materials flame retardant performance research field.
Description
Technical field
The utility model relates to a kind of strength testing device, belongs to glass performance study field.
Background technology
The development of fire-retardant science and technology, proposes more and more higher requirement to the assessment of fire proofing burning behavior, means of testing.Traditional method of testing (oxygen index method, vertical combustion, horizontal firing method) is although have the features such as simple to operate, quick, reproducible, still widely use in many combustion testing laboratories, but these method ubiquity test parameters are single, test result can not the shortcoming such as quantification, be difficult to be associated with the burning behavior of material in the true condition of a fire, sometimes to the assessment of commaterial, different experimental techniques is adopted to obtain conflicting result.Therefore, along with developing rapidly of fire-retardant science and technology, occurred various new means of testing, wherein most is representational is cone calorimetry.
To add the glass fiber material after fire retardant, when testing its fire resistance, utilize cone calorimetry can obtain the multinomial combustion parameter of glass fiber material, to study its fire resistance, but existing method cannot be measured for the intensity of layer of charcoal residual after burning, existing method is only by its compactness of scanning electron microscopic observation, but this method can only probably infer its intensity, and often there is deviation, intensity data really and accurately cannot be obtained, affect the research of anti-fire resistance to glass fiber material etc. and other correlated performances.
Summary of the invention
The purpose of this utility model is: residual layer of charcoal strength testing device after providing a kind of cone calorimetry sample to burn, to solve present stage, there is no corresponding effective strength meter for layer of charcoal residual after the burning of cone calorimetry sample, affect the problem to the anti-fire resistance of glass fiber material etc. and the research of other correlated performances.
For solving the problem, plan remains layer of charcoal strength testing device after adopting so a kind of cone calorimetry sample burning, and comprise spherical briquetting, the upper end of spherical briquetting is fixed on and is vertically slided on the slide block of setting, and the upper end of spherical briquetting is provided with pressure sensitive sheet.
Putting for the ease of sample, is provided with sample stage immediately below spherical briquetting;
In order to utilize existing experimental facilities, simplify installation and the project organization of this device, this device is arranged on universal testing machine, and described slide block is fixed on the moving beam of universal testing machine;
This device in use, layer of charcoal residual after the burning of cone calorimetry sample is placed in immediately below spherical briquetting, moving slider downwards, spherical briquetting is pressed in layer of charcoal until the spherical briquetting volume submerged in layer of charcoal exceedes over half, and slide block not with layer of charcoal joint, because pressure equals acting force divided by active area, the active area of spherical briquetting is the half of its spherical watch area, and acting force can obtain according to the gravity of pressure sensitive sheet and spherical briquetting, the intensity data of residual layer of charcoal after the burning of cone calorimetry sample can be calculated thus.
The utility model compared with prior art, major advantage is that this apparatus structure is very simple, change a little can realize for universal testing machine in the lab, and it is easy to operate, the intensity data of residual layer of charcoal after can measuring the burning of cone calorimetry sample quickly and accurately, the performance study tool of the materials such as the glass being added with fire retardant is of great significance, is suitable for being applied in experimental study field.
