Problems solved by technology

[0003] When the wind power blades reach the end of their service life, they need to be crushed. The crushed wind power blades will produce a large number of glass fibers of different thicknesses. Due to the strong heat resistance and corrosion resistance of glass fibers, they cannot be simply landfilled. These fibers are treated and prior art Portland cement siding does not perform well

Abstract

The invention discloses a glass fiber reinforced plastic fiber reinforced silicate cement wallboard manufacturing process, and relates to the technical field of cement wallboards. The purpose of improving the performance of the silicate cement wallboard through recycled fibers is achieved. The method specifically comprises the following steps: recycling glass fiber reinforced plastic fibers; preparing raw materials for manufacturing the silicate cement wallboard; the preparation method comprises the following steps: putting the recycled fibers and the preparation raw materials into a stirring pot according to the weight parts, slowly pouring a certain proportion of water into the stirring pot, and stirring for 1-3 minutes in an environment of 48n / min to obtain slurry; cleaning the mold, and spraying a layer of release agent on the working surface of the mold; pouring the slurry into a mold, and mechanically vibrating the slurry on a vibrating table for 3-8 minutes to compact the slurry; after the surface of the mold is flattened, the mold is put into a curing chamber, and initial curing is conducted for 1 d at the temperature of 20-35 DEG C until the mold is solidified; and demolding. When the wallboard is manufactured, the glass fiber reinforced plastic fibers are added, so that the ductility (bending resistance) of the Portland cement can be improved, and the service life of the Portland cement is prolonged.

Description

technical field [0001] The invention relates to the technical field of cement wallboards, in particular to a manufacturing process for fiberglass reinforced Portland cement wallboards. Background technique [0002] Current wind turbine blades are made of thermosetting resin-based composites reinforced with glass fibers (GF), carbon fibers (CF) or GF / CF blends. With the advent of the service life cycle of wind power blades, there will be more and more discarded wind power blades, and the pressure to save resources and protect the environment will become more and more serious. The recycling and reuse of thermosetting composite wind power blades has become a major key technology in the development of wind power. problem. [0003] When the wind power blades reach the end of their service life, they need to be crushed. The crushed wind power blades will produce a large number of glass fibers of different thicknesses. Due to the strong heat resistance and corrosion resistance of ...
