The Brief Introduction Of Glass Fiber Extraction Thimbles
Classically, the glass fiber extraction thimbles without rubber are made of 100% alkali-free glass fiber and are produced at high temperatures. There is no adhesive, and it’s chemically inert. The glass fiber extraction thimbles are used to collect fine and submicron particles, which is an efficient and high-quality filtration device for catching pollution source particles, acid mist, aerosol, beryllium compounds, etc.
It has the advantages of high-temperature resistance, low weight loss, high capture efficiency, and high strength, and can be widely used in the sample collection of pollution source particles, metal compounds and so on.
For example, in the monitoring of air pollution, the monitoring of smoke emission concentration has become more conventional and mature. There are clear requirements for quality control and management specifications. In daily monitoring, the sampling collection is mainly by glass fiber extraction thimbles. The key to the success of the experiment is the stability of the weight of extraction thimbles when sampling atmospheric particles.
No cracking is found in the base pressed after the glass fiber sleeve is added. Although the weld line is still visible on the part, there is no crack in the part. A simple test method is to apply the red or blue ink to the weld line of the shape of the part, to see if the ink is leaking out of the internal thread hole, and if the ink leaks out, it indicates that there is a crack there. The perfect shape is pursued in our production process.
