A kind of manufacturing method of pure glass fiber reinforced plastic fan

Abstract

The invention relates to a method for manufacturing a pure glass fiber reinforced plastic fan. It is characterized in that: after resin is impregnated with felt, platinum fiber cloth and steel wire cloth, the outermost layer is used as felt, and then platinum fiber cloth and felt are pasted alternately inside. Among them, two layers of symmetrically arranged platinum fiber cloth are replaced by steel wire cloth. When the felt, platinum fiber cloth, and steel wire cloth are pasted on adjacent layers, the fiber lines are cross-distributed. The resin content of the felt is 50-75% of the weight of the felt, the resin content of the steel cloth is 35-50% of the weight of the steel cloth, and the resin content of the platinum fiber cloth is 25-50% of the weight of the platinum fiber cloth. —40%. The resin content of the felt is 65% of the weight of the felt, the resin content of the steel wire cloth is 45% of the weight of the steel wire cloth, and the resin content of the platinum fiber cloth is 35% of the weight of the platinum fiber cloth. The curing time of the resin is 15-50 minutes. The demoulding time after pasting is at least 10 hours. The invention has the advantage that the front and rear discs and fan blades of the manufactured fan have strong tensile strength and impact toughness, which meets the needs of the chemical industry for corrosion-resistant fans.

Description

technical field [0001] The invention relates to a method for manufacturing a pure glass fiber reinforced plastic fan. Background technique [0002] At present, with the rapid development of the domestic chemical industry, people are paying more and more attention to the impact on the environment and ecology during the production process. Therefore, various fans are needed in the production process to deal with the discharge of various corrosive gases. Corrosion resistance is poor, so corrosion-resistant equipment is needed in the chemical industry, and some need to use expensive stainless steel, fluororubber, etc., resulting in a substantial increase in equipment costs, so people began to turn their attention to corrosion-resistant FRP In fact, because the pure FRP fan cannot withstand the tensile strength and impact toughness of the centrifugal fan, a composite FRP corrosion-resistant fan was developed, which is made of FRP fiber on the inner surface of the iron fan. Due to...
