Description

Technical Field

[0001] The invention relates to the technical field of fireproof board core paper performance detection, in particular to a fireproof board core paper performance detection device. Background Art

[0002] Fireproof board is a fire-resistant building material for surface decoration. Fireproof board is made of base paper through the impregnation process of melamine and phenolic resin and then through high temperature and high pressure environment. Fireproof board has stable performance and there is no limit on its processing size. Therefore, fireproof board is widely used. The performance characteristics of fireproof board mainly include: fire resistance, water resistance and mechanical strength. The quality of these three properties determines the excellent quality of fireproof board.

[0003] After the processing of the fireproof board is completed, its performance needs to be tested to determine whether its performance is qualified. The traditional fireproof performance testing method is to hold the fireproof board, make the corner of the fireproof board contact with the flame sprayed by the flamethrower for a period of time, and observe the burning marks on the surface of the fireproof board. The water resistance testing method is to directly immerse the fireproof board in water for a period of time, and observe whether it is deformed and cracked after taking it out. The mechanical strength test is to directly pressurize the fireproof board to observe whether the fireproof board after pressure is bent and deformed. The three testing methods require the use of at least three fireproof boards, and at least one device and manual long-term holding of the fireproof board for testing. The water resistance test of the fireproof board is only performed on the fireproof board with a complete surface. However, in actual use, the fireproof board generally comes into contact with water when a fire occurs and is extinguished. At this time, the surface of the fireproof board may have been damaged to a certain extent due to the burning of the flame, and when extinguishing the fire, the surface of the fireproof board may be damaged by the impact of the high-pressure water gun. Therefore, the traditional testing method does not conform to the actual application scenario and cannot obtain a more accurate test result. Summary of the invention

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 A fireproof board core paper performance detection device comprises a positioning unit 1 and a detection unit 2. The detection unit 2 is arranged on the positioning unit 1 for detecting the fireproof performance and water resistance of the fireproof board core paper. The positioning unit 1 detects the mechanical strength of the fireproof board core paper while positioning the fireproof board core paper. The positioning unit 1 comprises a fixed base 11.

A clamping member 14 is arranged at the left end of the rotating frame 13. A supporting member 15 is arranged on the clamping member 14. A pressure-applying member is arranged at the upper end of the clamping member 14. Component 16; the detection unit 2 includes a distance control cylinder 21, a distance control cylinder 21 is fixedly installed on the upper end of the fixed base 11, a detection box 22 is fixedly installed on the telescopic end of the distance control cylinder 21, and the detection box 22 is symmetrically provided with detection slots 23, a flame spray component 24 is arranged on the right side of the upper end of the fixed base 11 and in front of the detection box 22, a water spray component 25 is arranged on the left side of the upper end of the fixed base 11 and in front of the detection box 22, a recovery component 26 is arranged between the water spray component 25 and the detection slot 23 on the left, and a recovery component 27 is arranged between the water spray component 25 and the detection slot 23 on the right.

[0030] First, place two square pieces of fireproof board core paper cut off in the clamping member 14, and support the front bottom of the fireproof board core paper through the support member 15. At this time, the fireproof board core paper is clamped and fixed by the clamping member 14, thereby driving the support member 15 to rotate, and no longer supporting the front bottom of the fireproof board core paper. Apply fixed pressure to the surface of the fireproof board core paper through the pressure member 16, and observe whether the fireproof board core paper is deformed. If the fireproof board core paper is deformed, the quality of the fireproof board core paper does not meet the requirements, and no subsequent testing is required. If the fireproof board is not deformed, the clamping member 14 is driven to rotate downward by the rotating frame 13, so that the fireproof board core paper is vertically downward. Then, the detection box 22 is driven upward by the distance control cylinder 21 until the two fireproof board core papers extend into the detection groove 23, and water is sprayed onto the surface of the fireproof board core paper through the water spray component 25. After a period of time, the water that is not absorbed by the fireproof board core paper gathers in the detection groove 23 on the left side to soak the fireproof board core paper. Finally, the water is sent back to the water spray component 25 through the recovery component 26, and the water level difference is calculated. The volume of water absorbed by the fireproof board core paper is calculated according to the change in water volume, and the water absorption rate is calculated using the weight change of the fireproof board core paper before and after absorbing water. By comparing it with the water absorption rate required for the fireproof board core paper of qualified quality, it is determined whether the fireproof board core paper meets the quality requirements.

[0031] The fire-spraying component 24 is used to spray fire on the corners, side edges and surface of the fireproof board core paper on the right side. After a period of time, the fire-spraying is stopped and the burning marks on the surface of the fireproof board core paper are observed. The more obvious the marks are, the worse the fireproofness of the fireproof board core paper is. Conversely, the better. Then water is sprayed onto the surface of the fireproof board core paper on the right side through the recovery component 27 to simulate the impact force of high-pressure water on the fireproof board core paper during fire extinguishing. After a period of time, the degree of damage to the fireproof board core paper is observed, and the water in the right detection slot 23 is sent back to the water-spraying component 25 through the recovery component 27 to compare the water level changes. As mentioned above, by comparing with the water absorption rate required for the fireproof board core paper of qualified quality, it is determined whether the fireproof board core paper meets the quality requirements.

[0040] The working principle of the present invention: First, place the two cut square fireproof board core papers in the triangular groove 146 on the rectangular flat plate 141, and support the front bottom through the support plate 153 on the inverted C-shaped bracket 152. At this time, drive the threaded rod 144 to rotate through the motor one 133, thereby driving the pressing plate 145 to move downward until the hemispherical block 159 at the lower end of the pressing plate 145 contacts the traction rope 158 in the hemispherical groove 157. The traction rope 158 in the hemispherical groove 157 is squeezed. Under the limiting and guiding of the guiding column one 155 and the guiding column two 156, the cylindrical block 151 is pulled to rotate, thereby driving the inverted C-shaped bracket 152 and the support plate 153 to rotate until the support plate 153 no longer supports the front bottom of the fireproof board core paper. At the same time, the pressing plate 145 moves downward until it is in close contact with the rectangular flat plate 141 to fixedly clamp the rear side of the fireproof board core paper.

[0041] Then, the rectangular plate 164 is pressed down by the distance control cylinder 162, and the pressure plate 165 is moved downward to apply pressure to the surface of the fireproof board core paper. The pressure data applied by the distance control cylinder 162 is observed and recorded by the pressure sensor 163. After a period of time, it is observed whether the upper and lower end surfaces of the fireproof board core paper are parallel to the upper and lower end surfaces of the comparison plate 166 on the upper and lower sides, so as to judge whether the fireproof board core paper is deformed. If the fireproof board core paper is deformed, the quality of the fireproof board core paper does not meet the requirements and no subsequent inspection is required. If the fireproof board is not deformed, the bevel gear 134 is driven to rotate by the motor 133, thereby driving the rotating circular plate 132 and the connecting cylinder 137 to rotate downward, and the rectangular flat plate 141 rotates downward with the connecting cylinder 137, so that the fireproof board core paper is vertically downward.

[0042] At this time, the detection box 22 is driven to move upward by the distance control cylinder 21 until the two fireproof board core papers extend into the detection groove 23, and the initial water level in the water storage cylinder 251 is recorded by the water level measuring instrument 252, recorded as height 1, and the water in the water storage cylinder 251 is sprayed onto the surface of the fireproof board core paper through the booster water gun 254 through the water pump 1 253. After a period of time, the water not absorbed by the fireproof board core paper gathers in the detection groove 23 on the left side. At this time, the upper end of the limit tube 261 is flush with the horizontal diagonal line of the fireproof board core paper, so that the lower half of the fireproof board core paper is immersed in water, and the limit tube 261 is used to prevent the fireproof board core paper from being absorbed by the fireproof board core paper. Ensure that the water level in the detection tank 23 does not exceed the height of the limit tube 261. After a period of time, open the electric valve to allow the water in the detection tank 23 on the left to be transported to the water storage cylinder 251 through the drain pipe 2 266. At this time, by observing the surface of the fireproof board core paper on the left, it is determined whether it is damaged by the high-pressure impact. At the same time, the water level in the water storage cylinder 251 is measured by the water level measuring instrument 252 and recorded as height 1. The height 1 is compared with the height 2. The difference is the amount of water absorbed by the fireproof board core paper. According to the water absorption calculation formula, the water absorption rate of the fireproof board core paper is calculated. , by comparing the water absorption rate with the required water absorption rate of the fireproof board core paper of qualified quality, it is judged whether the fireproof board core paper meets the quality requirements. At this time, the fire spray nozzle 242 is used to spray fire to the corner, side and surface of the fireproof board core paper on the right side. After a period of time, the fire spraying is stopped, and the burning marks on the surface of the fireproof board core paper are observed. The more obvious the marks are, the worse the fireproof property of the fireproof board core paper is. On the contrary, the better, then the water in the water storage cylinder 251 is sprayed to the surface of the fireproof board core paper on the right side through the water pump 276 through the booster water gun 271, simulating the impact of water on the fireproof board core paper during fire extinguishing. Impact force, after a period of time, observe the degree of damage of the fireproof board core paper, open the electric valve 275, and let the water in the detection tank 23 on the right enter the water storage cylinder 251 through the drain pipe 3 273, and continue to measure the water level in the water storage cylinder 251 through the water level measuring instrument 252, and record it as height 3. The height 3 is compared with the height 2, and the difference is the amount of water absorbed by the fireproof board core paper. According to the water absorption rate calculation formula, the water absorption rate of the fireproof board core paper is calculated, and by comparing it with the water absorption rate required for the fireproof board core paper of qualified quality, it is determined whether the fireproof board core paper meets the quality requirements.
