Modern military and national defense fields have high requirements on the mobility of pyrotechnic aircraft. The better the mechanical properties of the pyrotechnic product, the higher the overall strength requirements and the stronger the ability to withstand motor overload. Therefore, pyrotechnics can use the...
For VOC sampling of wall coatings, a VOC discharge box is required. The standard VOC discharge boxes are 60L, 80L, 1000L, etc. Let's talk about the sampling requirements for using a 60L VOC discharge box as a wall paint VOC according to the GB/T 37884-2019 standard. According to the...
The paint voc release chamber is made of inert material, which is very particular about material selection because the inert material will not release or release a small amount of gaseous pollutants that affect the test. Secondly, the stability of the temperature and humidity in the box is also very important....
The voc discharge box can be used to test the release of volatile organic compounds from coatings. Common voc exhaust boxes are made of inert materials. Other components include air pump, air filter, voc filter, etc. Below, the editor of Ring Instrument will take you to understand the overall structure of the...
To measure the VOC release of paint, we will use the VOC discharge chamber. Next, the editor of the huanyi instrument will briefly introduce how to use the voc discharge tank to measure the VOC release of the paint. The test process of the VOC release amount of the...
In the determination of the VOC release of the coating, the VOC discharge chamber is often used. Then, what principle is used in the process of measuring the VOC of the coating? Let's find out. Determination principle of paint VOC release: 1. Use a Tenax-TA adsorption tube...
Before testing the VOC release amount of the paint, the VOC emission chamber needs to measure the background concentration of the VOC discharge cabin. Follow the steps below to measure the background dripping of the VOC discharge cabin. 1. After cleaning, the door of the environmental test...
According to national standards, the volatile harmful substances in the car need to pass the test. The following editors of the ring instrument have prepared a sampling method for in-vehicle VOC sampling through the vehicle voc environment chamber for your reference. A. Preparation before...
1.Overview of VOC Emissions Testing ASTM D5116 and ASTM D6670 guidelines are considered best practices in the industry and can be used for a variety of applications. The ASTM D5116 guidelines apply to testing representative samples in a small chamber, typically about 90 liters, and ASTM D6670 applies to...
