Introduction: After drying, micro moisture such as polyester chips and nylon 6 particles directly affects the spinning quality. At present, there are mainly differential pressure method, electrolysis method, Karl Fischer method and so on. The differential pressure method is fast, accurate, convenient, low cost and suitable for factories and enterprises. SF-1 differential pressure method micro moisture meter is mainly used for the determination of micro moisture after drying of polyester chips and nylon 6 particles in chemical fiber and plastic industry before melt spinning. It is in accordance with iso6188-1980 "plastics - Determination of moisture content in polyethylene terephthalate granules". The advantages of our own equipment are solved by self-assembly, which is convenient to use in the laboratory. characteristic:
1. Structure The instrument is mainly composed of differential pressure glass instrument, heater, automatic centering lifting device, temperature control instrument, vacuum gauge, vacuum pump, etc., and has been equipped with sodium molybdate reagent, vacuum grease, silicone oil, vacuum hose, mercury, syringe, vacuum pump interface and other spare parts. 2. Operation Turn on the power supply, set the required temperature of the temperature controller, raise the temperature and keep constant temperature; pour the sample to be measured into the test tube, and insert the test tube upward with the test tube interface of the differential pressure glass instrument; shake the right handle, and the heater rises to connect with the test tube, then the test can be carried out according to the standard operating procedures. Technical parameters: Temperature control range: room temperature ~ 250 ℃ Temperature fluctuation: & plusmn; 2.0 ℃ Vacuum: & le; 100Pa Determination range: 5-3000ppm (the corresponding sample volume is 3-0.5g, and the sample volume can reach about 10g) Power supply: 220 V 2A
