Meltblown nonwoven in the price is moderate, while the performance of excellent resistance to hydrolysis and acid and alkali corrosion, mainly used in the temperature requirements are not high, the moisture content is large working conditions.
Generally, the temperature resistance of polyester fiber is between 130℃ and 150℃. In order to overcome the shrinkage phenomenon of ordinary polyester needle-punched felt which has a temperature resistance of over 130℃ for a long time, the new filter felt with a working temperature of 150℃~170℃ is developed, so as to avoid the waste caused by using high-temperature filter material under some working conditions.
The needled felt improves the filtration accuracy of polyester fiber filter material and reduces the pressure drop, and it has the surface filtration effect of the coated filter material. In the series of medium and normal temperature filters, the polypropylene needled felt has the lowest temperature resistance, low running resistance and saves energy.In addition to the advantages of ordinary felt filter, and wear resistance is very good, with a high cost ratio and become the largest amount of felt filter species.
Acrylic fiber acupuncture filter felt temperature of 140~160 degrees Celsius, the use of imported fiber manufacturing, it is the best resistance to acid, alkali and hydrolysis resistance medium temperature filter material.
