Method for grading quartz sand by clamping quartz sand with glass-fiber reinforced plastic quartz-sand clamping tube through adopting wet process

Abstract

The invention discloses a method for grading quartz sand by clamping the quartz sand with a glass-fiber reinforced plastic quartz-sand clamping tube through adopting the wet process. The method comprises the following steps of: taking 15 parts by weight of accessory in a first group, wherein the accessory in the first group is quartz sand with the particle size of 0.6-0.9mm; taking 29 parts by weight of accessory in a second group, wherein the accessory in the second group is quartz sand with the particle size of 0.5-0.56mm; taking 25 parts by weight of accessory in a third group, wherein the accessory in the third group is quartz sand with the particle size of 0.45mm; taking 21 parts by weight of accessory in a fourth group, wherein the accessory in the fourth group is quartz sand with the particle size of 0.355mm; taking 8 parts by weight of accessory in a fifth group, wherein the accessory in the fifth group is quartz sand with the particle size of 0.3mm; taking 2 parts by weight of accessory in a sixth group, wherein the accessory in the sixth group is quartz sand with the particle size of 0.25mm; and mixing the six groups of accessories uniformly according to the corresponding parts. The quartz-sand clamping layer of a product has low content of resin and is highly compact, thus the stable quality of the product is guaranteed, and the cost of the product is lowered.

Description

technical field [0001] The invention relates to a quartz sand grading method, in particular to a quartz sand grading method for wet-process sand inclusion in glass fiber reinforced plastic sand inclusion pipes, which is suitable for the manufacturing process of glass fiber reinforced plastic sand inclusion pipes. Background technique [0002] At present, the quartz sand grading method used in the glass fiber reinforced plastic sand pipe industry can no longer meet the various technical indicators of the pipeline itself, and has an adverse effect on the various technical indicators of the pipeline itself. The existing quartz sand grading method has defects such as high resin content in the sand inclusion process, insufficient compactness of the sand inclusion layer, unstable product quality, and large consumption of raw materials.
