[0004] This application provides a combustion testing device for hair product material testing, including a main frame, a sample fixing and adjustment mechanism, a combustion system, a data acquisition and analysis system, and a control system. The main frame is a cuboid frame with wheels equipped with brakes installed at the bottom. High-temperature resistant transparent glass is installed around the perimeter and top of the main frame. The sample fixing and adjustment mechanism includes a sample holder located in the middle of the main frame, metal clamps fixedly mounted on the sample holder, and a slide rail between the sample holder and the main frame. The sample holder is fixedly mounted on the slide rail. The combustion system includes a ignition source generating device and a combustion environment control component. The data acquisition and analysis system includes multiple flame parameter sensors, smoke sensors, pressure sensors, and gas composition analysis sensors located within the main frame. The control system is located on the main frame and includes an independent touchscreen control panel.

[0005] The main frame of this application adopts a cuboid frame, equipped with wheels with brakes at the bottom for easy movement and fixation of the device; high-temperature resistant transparent glass is installed on all four sides and the top, ensuring that testers can clearly observe the combustion process while effectively insulating against heat and improving operational safety. The sample fixing and adjustment mechanism, with its combination of sample holder, metal clamps, and slide rails, enables stable clamping and precise position adjustment of hair sample products of different shapes and sizes, adapting to diverse testing needs and laying the foundation for accurate detection.

[0006] The combustion system provides the combustion conditions, the data acquisition and analysis system is responsible for data acquisition and processing, and the control system enables convenient operation. These systems work together to effectively control and detect the combustion process of hair products, achieving both accurate detection and convenient operation. Simultaneously, the data acquisition and analysis system can acquire various parameters through flame parameter sensors, smoke sensors, pressure sensors, and gas composition analysis sensors, enabling precise data reading of the combustion process and products, thus ensuring accurate test results.

[0007] In some embodiments of this application, the ignition source generating device includes an adjustable flame gas burner connected to a gas pipeline, on which a flow control valve is installed. During testing, the flame size can be precisely adjusted according to the testing requirements of different hair product materials, such as the flame height can be flexibly varied within a certain range, thereby simulating various combustion environments, improving the pertinence and accuracy of the test, and meeting the requirements for comprehensive and accurate testing of the flame retardant performance and combustion characteristics of hair product materials.

[0008] In some embodiments of this application, the combustion environment control component includes an oxygen concentration sensor, a temperature sensor, and a humidity sensor disposed within the main frame. These sensors can monitor the oxygen concentration, temperature, and humidity parameters inside the device in real time, and can work in conjunction with corresponding external supply and regulation systems to control various environmental parameters within a specific range, ensuring the stability and consistency of the testing environment. Different combustion environments can significantly affect the combustion process of hair products. Precise control of environmental parameters can avoid interference from external factors, making the test results more reliable and comparable, thereby improving the scientific validity and effectiveness of the detection.

[0009] In some embodiments of this application, the data processing and analysis system is connected to a data acquisition card and a computer via a data cable. The computer has dedicated testing software that can display data in real time, plot curves, and automatically calculate key parameters.

[0010] The data acquisition card is connected to a computer via a data cable, and dedicated testing software is used to display data in real time, plot curves, and automatically calculate key parameters.

Simultaneously, the intuitive data display and detailed test report generation facilitate quick and accurate analysis of the flammability of hair products by testing personnel, providing strong data support for material testing and helping to accurately determine the flame retardant properties and combustion characteristics of hair product materials.

[0011] In some embodiments of this application, the gas burner uses propane gas as fuel.

These sensors collect flame-related data in real time from multiple dimensions, providing a comprehensive and detailed reflection of the flame's combustion state. By monitoring and analyzing parameters such as flame temperature, height, and propagation speed, a deeper understanding of the dynamic changes in hair products during combustion can be obtained, providing crucial data for accurately assessing the flame-retardant properties and combustion characteristics of hair product materials, and helping to more accurately determine the quality and safety of hair products.

[0025] As people's demands for the quality and safety of hair products continue to increase, accurately testing the flame retardant properties and combustion characteristics of hair product materials has become crucial. Currently, existing combustion testing devices on the market have many shortcomings. For example, some devices cannot accurately control combustion environment parameters, such as oxygen concentration, temperature, and humidity, resulting in a lack of accuracy and comparability in test results; some devices have limited functionality in sample fixation and adjustment, making it difficult to adapt to hair product samples of different shapes and sizes.

[0029] Please refer to Figure 1 The combustion system may include a fire source generating device 31 and a combustion environment control component 32.

[0030] Please refer to Figure 1 The ignition source generating device 31 can use an adjustable flame size gas burner as the ignition source, using propane gas. It is installed at the bottom center of the device and connected to an external gas tank through a gas pipeline. The precision flow control valve on the gas pipeline can adjust the gas flow rate within the range of 0-5L / min, thereby achieving precise control of the flame height between 10-100mm.

[0034] Please refer to Figure 1 The data processing and analysis system can transmit the data collected by the sensor to the built-in data acquisition card of the device via a data cable, and then to a computer. The data is displayed in real time and curves are plotted through dedicated testing software. It can also automatically calculate key parameters such as combustion speed, flame duration, and smoke generation rate, and generate detailed test reports.

[0035] Please refer to Figure 1 The device can be designed to be fireproof and explosion-proof, meaning that the entire device is made of fireproof materials, has fireproof partitions inside, an explosion-proof pressure relief valve is installed on the top, and is equipped with an automatic fire extinguishing system to ensure the safe operation of the device.

[0036] Please refer to Figure 1 The rear of the device can be connected to a hazardous gas treatment device 6, which filters, adsorbs and neutralizes the hazardous gases produced by combustion before they are discharged in compliance with standards.

[0037] Safety warning signs are placed on the outside of the device, and protective railings are installed around it. Operators must wear protective equipment to ensure personal safety.

[0038] The combustion testing device for hair product material testing can be equipped with an independent touch screen control panel, which can set combustion test parameters, view the device's operating status and test data in real time, and also supports remote control function, enabling remote operation and monitoring via network.

[0043] Please refer to Figure 1 Example 1: Combustion performance test of ordinary synthetic fiber hair products.

[0044] Preparation: Move the device to a suitable test position using the bottom wheels 11, and lock the brake fixing device.

[0045] Open the control panel of the device and set the combustion environment parameters. Set the oxygen concentration to 21% (simulating a normal atmospheric environment), the temperature to 25℃, and the humidity to 50%RH. Adjust the flame height of the gas burner to 50mm by adjusting the gas flow control valve.

[0046] Select a cylindrical piece of ordinary synthetic hair product with a length of 20cm and a diameter of about 1cm, and fix it in place using the metal clamp 22 on the sample holder 21. Adjust the position of the sample by sliding the rail so that the vertical distance between the sample and the tip of the burner flame is 30mm, and adjust the angle of the sample holder 21 to 0 degrees (horizontal placement).

[0047] Combustion test process.

[0048] Click the electronic ignition button on the control panel to ignite the gas burner.

[0049] The combustion phenomenon of the hair product is observed and recorded, while various sensors within the device begin to operate. Flame temperature, flame height, and flame propagation speed sensors collect flame-related data in real time at a sampling frequency of 100Hz; smoke concentration and smoke composition analysis sensors monitor smoke generation; and pressure and gas composition analysis sensors record internal pressure changes and the concentration of harmful gas components.

[0050] The entire combustion process continues until the hair product is completely burned. During this time, the testing software displays various data curves in real time, such as the curve of flame temperature change over time and the curve of smoke concentration increase.

[0051] Data processing and analysis.

[0052] After the combustion test, the testing software automatically calculates key parameters of the hair product, such as the burning rate, flame duration, and smoke generation rate. For example, the calculation shows that the burning rate of this synthetic fiber hair product is 5 mm / min, the flame duration is 120 s, and the smoke generation rate is 3 mg / s.

[0053] Based on the calculation results and the combustion phenomena and data curves recorded during the test, combined with relevant hair product material testing standards, the flame retardant performance and combustion characteristics of this ordinary chemical fiber hair product are evaluated, and a detailed test report is generated.

[0054] Please refer to Figure 1 Example 2: Comparative combustion test of natural hair products and synthetic fiber blended hair products.

[0055] Preparation.

[0056] First, fix the device and set the combustion environment parameters. Set the oxygen concentration to 18% to simulate a relatively low oxygen environment; set the temperature to 30℃ and the humidity to 60%RH; adjust the flame height of the gas burner to 30mm.

[0057] Select a section of natural hair product of the same specifications as in Example 1 and a section of hair product made by mixing natural hair and synthetic fibers in a 1:1 ratio. Fix the natural hair product on the sample holder 21 and adjust its position so that the vertical distance from the flame tip is 25mm and the angle is 15 degrees. After fixing the mixed hair product, adjust its position so that the vertical distance from the flame tip is 25mm and the angle is also 15 degrees.

[0058] Combustion test process.

[0059] Ignition and combustion tests were conducted on natural hair products and blended hair products in sequence. During the tests, various sensors collected data in real time and recorded data such as combustion phenomena, flame parameters, smoke parameters, pressure changes and gas composition of the two types of hair products under the same combustion environment.

[0060] It was observed that natural hair products burned with a gentler flame and produced relatively less smoke; while blended hair products burned with a more intense flame and produced significantly more smoke.

[0061] Data processing and analysis.

[0062] The testing software calculated various combustion parameters for the two types of hair products. For example, the combustion speed of the natural hair product was 3 mm / min, the flame duration was 90 s, and the smoke generation rate was 2 mg / s; the combustion speed of the mixed hair product was 6 mm / min, the flame duration was 150 s, and the smoke generation rate was 4 mg / s.

[0063] By comparing the combustion parameters and test phenomena of two types of hair products, the differences in their flame retardant properties and combustion characteristics are analyzed, and a test report containing the comparison results is generated, providing a basis for the quality assessment and performance improvement of hair product materials.

[0064] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.

Therefore, the scope of protection of this application should be determined by the scope of the claims.
