SF YaDifferential pressure micro moisture analyzerThe moisture content of polyester chips is one of the important indicators for controlling the drying quality of chips in polyester production. The moisture content will directly affect the physical and mechanical properties of the spun fibers. Even if dry slices contain trace amounts of water, the hydrolysis of ester bonds in the high-temperature melting process will still promote the breakage of molecular chains and a decrease in molecular weight. Therefore, controlling the moisture content of dry slices is very important. Usually, the moisture content of the slices used for spinning short fibers in production needs to be controlled between 0.007-0.01 percent; The control range for ordinary filament is 0.005-0.008%; The control for high-speed spinning of filament is less than 0.005%, preferably less than 0.003%. The SF differential pressure micro moisture analyzer is an industrialized scientific research product developed by Shanghai Chengya Chemical Fiber Co., Ltd. It is suitable for measuring the moisture content of polyester cutting, nylon slicing, and plastic particles in the textile industry. The range of moisture content is 5~5000PPm. The vacuum degree can reach within 5Pa. The temperature range is from room temperature to 300 degrees Celsius.
