Summer and early autumn are the active seasons for mosquitoes. After a mosquito bite, it is not only difficult to itch, but mosquito bites can spread diseases and have potential health risks. Mosquito-antimony liquid is a new type of anti-mosquito that appears after mosquito spray and mosquito-repellent incense. Its main components are pyrethrins, solvents, stabilizers, and flavors. Pyrethrin is the main active ingredient of mosquito liquid, which can paralyze the nerves of mosquitoes and achieve the purpose of removing mosquitoes, but it is less harmful to the human body and can be excreted with metabolism after entering the human body. Therefore, mosquito liquid is very popular.

Test significance:
Mosquito-fluxing liquids are generally used in combination with electric heating plates, namely electric repellent liquids, which can evenly disperse the active ingredients of insect repellent liquids in space at a certain temperature, and can be used continuously for a long time. A bottle of insect repellent liquid can be used. 20 to 40 days, very convenient. At the same time, electrothermal mosquito-repellent incense liquid also put forward higher requirements for its packaging design, material and package sealing. Leakage is one of the most common problems in the common problems of mosquito liquids. During the storage and transportation process, the liquid of mosquito coils will inevitably lead to inversions and bumps, which will lead to leakage of the package. Even changes in temperature and pressure that occur in cities with low temperatures such as high temperatures or from the plains to the plateau will lead to package leakage. Leakage rate increase.
test instrument:
Labthink PARAM MFY-01 seal test instrument is specialized for food, pharmaceuticals, medical devices, chemical, automotive, electronic components, stationery and other industries bags, bottles, tubes, sealing test cans, boxes and other equipment, The sealing performance test of the test piece after the drop and pressure test can also be performed. The instrument adopts digital preset test vacuum degree and vacuum holding time to ensure the accuracy of the test data; automatic constant pressure replenishment is adopted to ensure that the test can be performed under preset vacuum conditions; automatic feedback unloading and automatic end test are supported. Ensure the smooth progress of the test process.
The test principle of the instrument is to determine the sealing performance of the sample by measuring the internal and external pressure difference of the sample immersed in water by evacuating the vacuum chamber so as to determine the sealing performance of the sample; by vacuuming the vacuum chamber, The internal and external pressure difference of the sample is generated, and the sealing performance of the sample is determined by observing the expansion of the sample and releasing the shape of the sample after releasing the vacuum. The instrument meets many national and international standards such as GB/T 15171 and ASTM D3078 .
Testing process:
The tank seal Tester MFY-01 into the amount of distilled water, the test sample is placed in water, covered with the sealing cap of the vacuum chamber, the maximum set pressure value is -90 KPa, the vacuum pump starts evacuation of the vacuum chamber The beginning of the test, pay close attention to the observation of the sample, observe whether there is a continuous bubble overflow or leakage of liquid, if this does not happen, then set the pressure value for 30 s , continue to observe. If there is no open air bubble or no liquid spill, then the sample seal is good.

to sum up:
By testing the sealing performance of the mosquito liquid package, it is possible to prevent and control the leakage of mosquito liquid. Use of Labthink MFY-01 seal test apparatus can detect mosquito liquid sealing performance of the package, the package quality can effectively visually determine the mosquito liquid. Mosquito-fluxing liquid is only a typical representative of daily-use packaging containers, and other plastic packaging containers and other sealing performance tests can follow this test method. Labthink has been committed to providing professional testing services and equipment for customers around the world. Over the years, it has provided professional sealing performance testing services to customers worldwide, providing customers with reliable technical support. Customers are welcome to log on Jinan Languang's website for detailed information or to call us . Labthink hopes to enhance the technical exchanges and cooperation with enterprises and institutions in the industry.
