How to Detect the Volatile Substance Content of Car Seat Leather

This article describes the process of testing the atomization performance of car seat leather using the SCHAP Super Atomization Tester Hart and presents the detection of volatile substances. in car interior accessories and accessories. volatile matter content method and details the parameters, scope of application and other information of the atomization tester, thereby providing a reference for companies to monitor the volatile matter content in automobile interior materials

Everything in the automobile The volatile content of jewelry and accessories has a great impact on the air quality inside the car, the visibility on the windshield and the safety of conduct. This article describes the process of testing the atomization performance of car seat leather using the Labthink FT-F1 Atomization Tester and more.discusses the method for detecting volatile content in automobile interior accessories and accessories, and details the parameters of the atomization tester. Scope of application and other information, thereby providing a reference for companies to monitor the volatile content of automobile interior materials.

The content of volatile substances in the passenger compartment of a car is an important factor affecting the internal environment of the car and driving visibility. In the process of production and functional improvement of automobile interior products, small molecular substances are likely to be introduced into them, and these introduced substances are volatile, especially when the internal temperature of the car is high, these substances are more volatile. Small molecular substances emitted from the interior of the car can float in the air, pollute the ambient air inside the car, endangerharm human health when inhaled or condense on car windows, negatively affect driving visibility and threaten driving safety. . Therefore, how to test the content of volatile substances in automobile interior parts is a common concern in the automobile industry.

The content of volatile substances in automobile interior parts is characterized by atomization performance and verified by atomization testing, which mainly includes three testing methods: atomization method shine, mist method and weighing. The first two methods focus on assessing the impact of volatile substances on driving visibility, while the latter focuses on testing the content of volatile substances in the sample. Currently, among the three methods, the weighing method and the gloss method are widely used.

TheReference standards for atomization testing include QB/T 2728-2005 \"Determination of atomization performance of physical and mechanical tests of leather\", DIN 75201-1992 \"Automotive interior materials\" Determination of fogging properties\", BS EN 14288-2003 \"Determination of fogging properties of leather for physical and mechanical tests\", etc.

3. Test sample

This article mainly uses the weighing method to test the atomization performance of leather for a certain car seat.

4.Testing Equipment

This item uses the SCHAP Super Hart atomization tester independently developed by qisnun Co., Ltd. to test the samples. Tests capable of atomization.

4.1 Principle of the test

The test is done by increasing The temperature accelerates the volatilization of small molecular substances in automobile interior parts to rshorten the volatilization time. During the test, the sample is placed in the misting cup and an aluminum foil or glass plate is placed on top of the misting cup. The misting cup is placed in the heating tank of the misting tester for heating, and the aluminum foil or glass plate above passes through the cooling device. Let cool. The gas volatilized in the sample will condense on the surface of the cooled aluminum foil or glass plate. By testing the optical properties of the SS glaplate or the weight change of the aluminum foil before and after condensation, the atomization performance of the sample can be obtained.

4.2 Scope of application

(1) Suitable for interior materials such as automobiles and aircraft, such as the interior plastic of automobile parts It can also be used to evaluateprevent the evaporation of volatile components from polyurethane, textiles, leather, adhesives, non-woven fabrics and other materials at high temperatures. It can also be used to measure the high temperature fogging phenomenon of xenon lamps in front of cars.

(2) Suitable for high temperature volatile component testing of plastic raw material particles.

(3) It can be extended to the volatility testing of carpets, leather, sponges, rubber and other products under high temperature conditions.

(4) Can meet multiple national and international standards, such as ISO 6452, DIN 75201, SAE J1756, QB/T 2728, BS EN14288, PV 3920,NES M0161 , TSM 0503G etc.

4.3 Equipment parameters

l The temperature control range of the high temperature tank is ambient temperature ~ 150 ℃ and the temperature control accuracy is ±0.1℃.

l The temperature control range of the low temperature tank is 0~100℃, and the temperature control accuracy is ±0.1℃.

l 6 test position designs, sample tests and blank tests can be carried out at the same time.

l The equipment works stably and provides users with accurate and reliable detection data.

5. Testing Process

(1) Open the atomization tester and adjust the temperature parameters so that the high temperature tank temperature controls at 100℃.

(2) Cut 3 samples with a diameter of 80 mm from the sample surface and place them in a desiccator to dry for at least 2 seconds under the environmental conditions of 23±2℃. sky.

(3) Clean the fog light cup thoroughly and dry it completely.

(4) Weigh accuratelytake the weight of the aluminum foil and record it.

(5) Place the samples in three misting cups respectively, take another misting cup and add 10 ± 0.1 g of the standard substance dioctyl phthalate Perform a control test with ester (DOP). Place the sealing rings, weighed aluminum foil sheets, glass sheets and filter paper on top of the misting cup in order.

(6) Place the misting cup into the high temperature tank of the atomization tester which has been constant temperature at 100℃, place the cooling plate on the paper filter and the cooling water temperature is 21℃. Heat for 16 hours.

(7) Remove the aluminum foil, place it in a desiccator with the spray side up, dry it for 3.5-4 hours and weigh - it with precision. The difference in weight of the fealuminum oil before and after the test corresponds to the atomization value of the sample.

6. Test Results

The masses of the components condensed on the aluminum foil surface of the three samples were 2.31 mg and 2.25 mg, respectively. , 2.29 mg. The atomization value of the DOP standard substance in this test was 4.93 mg. The atomization value of DOP standard substance is 4.90 ± 0.25 mg, which means that the test conditions are not abnormal and the test results are valid. Therefore, the atomization value of the sample tested in this article is 2.28 mg (the average of the test results of the three samples).
