 1. Corrosion resistance: Polypropylene has excellent chemical resistance, for inorganic compounds, regardless of acid, alkali, salt solutions, in addition to strong oxidizing materials, almost all of its 100 ℃ until no detrimental effect on almost all solvents at room temperature By not dissolved, a general alkyl, diameter, alcohols, phenols, aldehydes, ketones and other media can be used. 2. Temperature Resistance: Polypropylene plastic melting point of 164-174 ℃, so the general use temperature up to 110-125 ℃. 3. Non-toxic: does not scale, do not pollute the media, it can also be used in the food industry. 4. Light weight: for equipment installation and maintenance is very convenient.
Third, the tube heat exchanger applications:
This device is suitable for use in a variety of make chemicals, light industry, metallurgy, pharmaceutical, food, chemical and other industrial heat transfer equipment, particularly appropriate as a condenser, instead of the original stainless steel, enamel, graphite, glass condenser.
