example 1
[0008] Take 80kg of 320-800mesh fly ash, 80kg of wollastonite, 28kg of polyvinyl chloride resin, carbon black, zinc borate, 4kg of compound modification additives, etc., and dry them with a high-speed shear mixer at 110-150°C for 1-1.5 hours for fully coupled cross-linking. Put the uniformly mixed material into a high-temperature extrusion granulator for granulation. The particle size is 3-5mm, and the particle length is 0.5-1.5cm. Extrude the pellets through a single-screw or conical twin-screw extruder equipped with a special mold at 120-240°C, then press out three-dimensional patterns on the surface, and cool with water to form a calcium-wood composite board substrate. The board-shaped substrate is based on Use occasions and size requirements Use an infrared control cutting machine to cut to the required size, and pack it into the warehouse after passing the inspection.
