Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fire resistance performance detection of glass products, and relates to a fireproof glass fire resistance performance testing device and a use method thereof. BACKGROUND

[0002] The ability of glass material to continuously contact a flame for a long time without being damaged is referred to as fire resistance performance. The fire resistance performance is an important performance of fireproof glass. When a material is continuously subjected to flame roasting for a long time, thermal stress is generated due to mutual restriction of deformations of parts of the material, and when the thermal stress exceeds the ultimate strength of the material, the material is damaged in the form of collapse, peeling and fracture. The fire resistance performance of the material is mainly determined by the thermal expansion coefficient, thermal conductivity, fracture toughness, specific heat, strength and the like of the material, and is also related to the organizational structure, shape and size of the material.

[0003] The fireproof glass is applied to building materials such as glass curtain walls and daylighting roofs, and has high requirements for the fire resistance performance thereof. In order to ensure that the fireproof glass has fire resistance integrity when used and personnel safety evacuation in the event of a fire or the like, the fire resistance performance of the material is often tested during the research of the material.

[0004] At present, there are few devices specially used for fire resistance experiments. The traditional method is to fix the sample to be tested on a platform and use a flame spray gun to test the sample by flame spraying. However, an operator needs to use a stopwatch to stay near the test platform throughout the test, and record the time when the glass breaks. Since the fireproof glass has excellent fireproof performance, the single test time is too long, which greatly reduces the work efficiency of the operator. In addition, the temperature near the test instrument is high, and the use of flammable gas in the flame spray gun is dangerous. When the glass explodes, the broken glass pieces may injure the operator. The speed of each experimenter is different, and the test repeatability is poor. Therefore, the accuracy of the experimental results obtained by the traditional method is not high, and the danger is great. SUMMARY

[0005] The application aims to solve the problems of low efficiency and great danger of the existing glass fire resistance performance test method, and provides a fireproof glass fire resistance performance testing device and a use method thereof.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the application is as follows:

[0007] A kind of fireproof glass fire resistance testing device, it is characterized in that including the following equipment: fuel storage tank (10) is connected to test equipment (0) by fuel pipeline (9), wherein in test equipment (0) fuel pipeline (9) is connected with flame spray gun (4), the lower part of flame spray gun (4) is equipped with flame spray gun table (6), flame spray gun table (6) is arranged on sliding rail (7), and baffle (5) is arranged at the end of sliding rail (7);Flame spray gun (4) is correspondingly provided with the sample table (2) to be measured at the nozzle, and gravity sensor (3) is arranged on the sample table (2) to be measured, and the upper part of gravity sensor (3) is equipped with the fixture (1) of fixed glass sample.

[0008] Further, the test equipment (0) is provided with an electronic watch (8), which is connected with the gravity sensor (3), so as to ensure that the electronic watch is paused when the weight of the glass sample changes for the first time.

[0009] Further, the distance between the nozzle of the flame spray gun (4) and the surface of the glass sample to be measured is 10 mm, and the flame is sprayed at the center position of the glass sample.

[0010] Further, the fixed glass sample fixture (1) can fix the glass sample to be measured with a length of 100-150 mm.

[0011] Further, the height of the flame spray gun (4) can be adjusted to meet the testing needs of glass samples of different sizes.

[0012] Further, the flame spray gun table (6) can move left and right.

[0013] Further, the fuel pipeline (9) is made of rubber hose.

[0014] Further, the fuel in the fuel storage tank (10) is any one of butane and acetylene.

[0015] Further, the glass sample is made of raw materials with the following weight percentages: SiO2: 75-80%, B2O3: 8-12%, Y2O3: 1-4%, ZrO2: 0.1-2%, Na2O: 1-8%, NaCl: 0.1-1.5%.

[0016] The addition of Y2O3 in the glass sample reduces the number of non-bridge oxygen in the glass network structure, re-aggregates the isolated island-shaped network units, enhances the network structure of the glass, and thus makes the atomic arrangement in the glass structure more compact, thereby reducing the thermal expansion coefficient of the glass; ZrO2 is an intermediate oxide that can reduce the thermal expansion coefficient of the glass, but a high content of ZrO2 will increase the viscosity of the glass, making it difficult to process the glass, therefore, the amount of ZrO2 is controlled in the present application to be 0.1-2%.

[0017] A method for using a fireproof glass fire resistance testing device, characterized in that it comprises the following steps:

[0018] S1: first, fix the glass sample to be tested on the sample table (2) through the glass sample clamp (1), adjust the position of the flame spray gun table (6) and the flame spray gun (4) so that the head of the flame spray gun is 10 mm away from the surface of the glass sample, and the sprayed flame is at the center of the glass sample;

[0019] S2: open the valve of the fuel storage tank (10), ignite, adjust the flame to be blue, and start the electronic watch (8) to automatically time;

[0020] S3: when the glass cracks due to continuous heating, the gravity sensor (3) in the sample table (2) senses and transmits a signal to the electronic watch (8), the electronic watch (8) stops timing, the operator records the time, puts in a new glass sample to be tested, and repeats the above test.

[0021] The beneficial effects of the present application are:

[0022] 1. The device has a simple structure, a sliding rail is arranged below the flame spray gun table, the flame spray gun table can move left and right, the height of the flame spray gun can be adjusted to meet the testing needs of glass samples of different sizes, and the test device is simple to operate, which can effectively avoid the problem of glass fragments injuring people when the glass cracks due to heating.

[0023] 2. When the device is used to test the heat resistance of glass products, the weight sensor below the glass senses and stops the electronic time recording watch from recording time when the glass cracks or explodes due to heating, thereby avoiding errors caused by human factors. The device can also effectively improve the work efficiency of the operator, so that the operator does not need to stay near the equipment for a long time. BRIEF DESCRIPTION OF DRAWINGS
