Abstract
The invention relates to a preparation method of a compression resistant and wear resistant composite tube for conveying mortar and stone slurry. The method comprises the following steps: uniformly mixing 100 parts of quartz sand particles, 0-30 parts of calcium carbonate particles and 15-25 parts of resin adhesive to prepare a wear resistant inner material and then evenly coating the wear resistant inner material on the inner wall of a high-density polyethylene base tube. The inner wall material of the composite tube using quartz sand and calcium carbonate particles as main materials has better wear resistance; and after the composite tube is used for a while, the inner wall of the composite tube become more smooth so that the coefficient of friction with materials is smaller, the flow resistance of materials is lower and the friction of material with the inner wall of the composite tube is lower. The inner wall of the composite tube is fine and smooth and has no damages after being continuously used in the slurry pump section.
Description
(1), technical field the present invention relates to a kind of manufacture method of liquid delivery tube.Be particularly related to a kind of manufacture method of composite pipe that is used to carry sandstone slurries with resistance to compression, wear-resisting characteristics.Described composite pipe is mainly used in liquid materials such as transfer ore pulp, concrete slurry and mortar.
(2), the existing pipeline that is used for transfer ore pulp, concrete slurry and mortar of background technique generally is divided into metal tube and polyethylene pipe two big classes.Wherein, metal tube has good rigidly, and the characteristics that compression resistance is good, but corrosion-resistant are easily got rusty, than great, and installation cost height.
Though polyethylene pipe proportion is little, the low and good corrosion resistance of installation cost, the ubiquity rigidity is bad, the shortcoming of compression resistance difference.Especially, owing to contain a large amount of granular ores, sandstone, ore pulp, concrete slurry and mortar are very serious for the wearing and tearing of polyethylene pipe inwall, cause existing polyethylene pipe wear resistance can not meet the demands far away.Three big state-owned gold mine tests show that when common polyethylene pipe was used to carry the gold mine ore pulp, the pipeline that close ore pulp pump is a section had only about 80 days working life in Laizhou City, Shandong Province.
(3), summary of the invention the present invention aims to provide a kind of manufacture method of compression resistant and wear resistant composite tube for conveying mortar and stone slurry, prepared composite pipe is used to overcome that existing polyethylene pipe wears no resistance and the defective of poor rigidity.Technical problem to be solved is, first, increase substantially the wear-resisting property of inner tube wall, and make the conveying of its suitable ore pulp, concrete slurry and mortar and have long working life.The second, increase substantially the rigidity and the bearing capacity of composite pipe.
The present invention is that to solve the problems of the technologies described above the technological scheme that is adopted as follows:
A kind of manufacture method of compression resistant and wear resistant composite tube for conveying mortar and stone slurry is characterized in that:
1), prepares the wear resistant inner layer material: 50~100 purpose quartz sand particles that with weight portion are 100 parts, weight portion is 0~30 part 50~100 purpose calcium carbonate granules, weight portion is that 15~25 parts resin binder mixes, and stirs, and makes the wear resistant inner layer material;
2), with the wear resistant inner layer coated materials in high density polyethylene (HDPE) basis inner tube wall: an end is sealed, charging aperture is left at the other end center, the high density polyethylene (HDPE) basis pipe level of wall thickness 1~2cm places on the equipment that drives this high density polyethylene (HDPE) basis pipe rotation, driving this high density polyethylene (HDPE) basis pipe when described charging aperture adds the wear resistant inner layer material rotates around the tube hub axle, more than the rotating speed 2500rpm, be coated on the thickness 0.5~1.5cm of high density polyethylene (HDPE) basis inner tube wall equably up to the wear resistant inner layer material; Common process solidifies.
Good effect of the present invention is: (1), be that the composite pipe inner-wall material of major ingredient has wear-resisting property preferably with silica sand and calcium carbonate granule, and after using after a while, the composite pipe inwall is Paint Gloss, diminish with the friction factor of storeroom, the Flow of Goods and Materials resistance is littler, and is littler to composite pipe inwall frictional force.In the burnt tame gold mine transfer ore pulp test of Shandong gold group, use the composite pipe 15 months that the present invention prepares, composite pipe inner wall smooth, careful, not damaged continuously in ore pulp pump section.(2), increased the wear resistant inner layer material, particularly increased seamless steel pipe after, composite pipe rigidity of the present invention, compressive strength increase substantially.
