Introduction of Extraction Thimbles
1.Classification of extraction thimbles
The extraction thimble, as its name implies, is a cylindrical element used for extracting. According to the material, it can be divided into three categories: cellulose exaction thimbles, glass fiber exaction thimbles, and quartz fiber exaction thimbles. As quartz fiber exaction thimbles cannot be produced in China at present, our company is mainly the first two products. In addition, the material and function of the filter cartridge and filter paper are similar.
2.Application of the difference between extraction thimbles
Cellulose exaction thimbles
The filter cartridge is suitable for general cable extraction. It is mainly used for indoor dust control and extraction of indoor toxic substances (terephthalic acid).
Glass fiber exaction thimbles
Glass fiber filter cartridge is suitable for Soxhlet extraction when cellulose filter cartridge temperature is higher than 120 C and strong acid is not available for trial use.
In addition, there are fixed pollution sources of flue gas, smoke and dust detection, such as cadmium, nickel, tin, fluoride and so on, as well as fixed pollution sources of waste gas benzo ratio, lead, asphalt smoke, sulfuric acid fog, environmental air and waste gas arsenic, dioxins and so on.
