Abstract

The invention discloses a composite resin filter-pressing plate. The composite resin filter-pressing plate is prepared from the following raw materials of, by weight, 150-250 parts of polyolefin high polymer materials, 3-8 parts of thermoplastic elastomer SBS, 30-40 parts of glass fibers, 3-8 parts of a titanate coupling agent, 50-60 parts of calcium carbonate, 10-20 parts of modified zeolite, 30-40 parts of hollow glass beads, and 1-3 parts of an antioxidant. The invention further provides a preparation method of the composite resin filter-pressing plate. Since the manufacturing materials and the manufacturing method are changed, the filtering efficiency of the manufactured filter-pressing plate is greatly improved, the compressive strength of the filter-pressing plate pressed at a high temperature and under high pressure reaches 360 kg / cm<2>, and the shock resistance and the compressive strength performance of the filter-pressing plate are good.

Description

technical field [0001] The invention relates to the technical field of filter plates of filter machines, in particular to a composite resin press filter plate and a preparation method thereof. Background technique [0002] Ceramic filter is a kind of equipment for solid-liquid separation, because the medium for solid-liquid separation is ceramic filter press plate, the core component of which is ceramic filter press plate, which is a porous ceramic containing tiny capillaries. The principle of solid-liquid separation is capillary theory. According to Kelvin's law, as long as the capillary diameter is controlled within a certain range, the required capillary force can be achieved. At this time, the filter plate is filled with liquid, but the air cannot pass through. Under the action of a small vacuum, the vacuum inside the filter plate keeps rising, making the filter cake sucked and hung outside the filter plate thicker and thicker, and the liquid flowing into the filter plat...
