The function and composition of pre drying primer 1、 Function of gas infrared pre drying and priming machine Before drying, the dyed fabric needs to remove part of the moisture quickly, otherwise, the dye molecules will migrate and lead to uneven color. The process of rapid moisture removal is pre drying and priming process, which usually uses electric infrared heating. The electric infrared heating system not only has high energy cost, but also has severe decline of heating elements and short service life. The more moisture removed in the pre drying process, the more uniform the color and better the quality of the finished fabric, and the less energy consumed in the subsequent drying process. 2、 Composition of gas infrared pre drying primer 1. Gas infrared burner Combined burner is adopted, which is fast and convenient to replace; High infrared radiation efficiency: the heat generated by gas combustion is mainly radiated to the cloth in the form of infrared, heating quickly; Uniform burning: uniform burning along the width direction of the cloth can ensure uniform drying of the cloth; Not easy to temper: the special burner structure solves the problem of easy tempering of fully premixed burner; Small thermal inertia: after shutdown, the burning surface can be reduced from the high temperature of working state to the normal temperature that can be touched directly in a few seconds. Once power failure is caused by accident, the waste heat of burning surface will not cause fire, which is very important for safety production. 2. Combustion control system With gas leak detection function: before starting the system, check the leakage of the valve group, if there is gas leakage, the system will be locked automatically; It has the functions of pre purge, automatic ignition, flame detection, flameout protection, gas pressure protection, air pressure protection, unexpected shutdown alarm, etc; 3. Gas system Equipped with gas filtration and pressure stabilization system; 4. Air supply and filtration system The combustion air is filtered before entering the burner, otherwise it may cause foreign matters to block the pipeline or burner; 5. Air and humidity exhaust system According to the humidity, the exhaust air volume is controlled accurately;
