Abstract

The invention provides a hybrid fiber grid fabric reinforced polypropylene compound filtering plate and a preparation method thereof. A complex fiber reinforced polypropylene, which is formed by weaving inorganic fiber with organic fiber, is taken as a main material of the filtering plate. The filtering plate is prepared from the following components in parts by weight in the manner of die-cast formation: polypropylene resin, inorganic mineral powder, continuous inorganic fiber, continuous organic fiber, coupling agent, antioxidant and lubricating oil. According to the preparation method provided by the invention, due to the compound components and structure characteristics of gridding cloth, the whole structure and mechanical properties of the filtering plate are isotropic. A molding method of gradually increasing pressure and temperature and maintaining pressure and temperature is adopted and pressing molding under room temperature is performed, so that the internal stress of the filtering plate is relieved and the compactness, density and size of the filtering plate are stable and uniform.

Description

Technical field [0001] The invention relates to the field of filter presses of filtration equipment, in particular to a hybrid fiber mesh fabric reinforced polypropylene composite filter plate and a preparation method thereof. Background technique [0002] Filter press is a commonly used solid-liquid separation equipment. The filter mechanism is the core component of the filter press, and the filter plate is the key element of the filter mechanism. Its material and performance play a vital role in material filtration and directly determine Whether the filter mechanism can operate normally or not is related to the service life and filtering effect of the filter press. The material to be filtered enters each filter chamber from the feed hole on the thrust plate of the filter press, and the filter cloth is compressed by the pressure between the plate and frame. The solid particles are trapped in the filter chamber because the particle size is larger than the pore size of the filter ...
