METHODS OF PRODUCTION OF A HEAT-RESISTANT FILTER ELEMENT |
摘要 |
<p>A subject for the invention is to provide a low-cost heat-resistant filter element produced from polyethylene particles which is for use in separating and collecting particles from a dust gas, can be continuously used even in a high-temperature environment of about from 70 DEG C to 130 DEG C, especially from 90 DEG C to 110 DEG C, is excellent in chemical resistance, and has flexibility and excellent suitability for mass production. Another subject is to provide processes by which the heat-resistant filter element can be produced at a reduced equipment cost while taking care of the environment. <??>In the invention, a coating layer of a fluororesin was formed on a surface of a permeable porous molding obtained from particles of a resin composition containing a polyethylene as a main component of a resin ingredient and from 0.1 to 3 parts by weight of an antioxidant per 100 parts by weight of the resin ingredient by fusion-bonding the particles to one another at the surface thereof. <IMAGE></p> |
