Anti-scaling mining pipe and preparation method thereof

Abstract

The invention discloses an anti-scaling mining pipe and a preparation method thereof, and belongs to the technical field of mining pipes. In the prior art, a fluorine-containing polyolefin material is mostly attached to the inner wall of a water supply pipeline so as to reduce the adsorbability of the inner wall to sediments and further reduce the possibility of blockage, but the technical defect is that the inner wall is extremely easy to wear due to the fact that the inner wall bears the circulation of liquid containing solid sediments for a long time, and the anti-scaling function is lost. The invention provides an anti-scaling mining pipe. The anti-scaling mining pipe is prepared from components in parts by weight as follows: 65-85 parts of polyolefin, 1-2 parts of an antioxidant, 5-30 parts of fluororesin, 0.5-1 part of a compatilizer and 0-3 parts of an anti-hydrolysis agent. The polyolefin, the fluororesin and the compatilizer are matched, so that the wear resistance of the pipe is remarkably improved, the free energy and the friction coefficient are reduced, scaling is prevented, and the flow resistance is reduced.

Description

technical field [0001] An anti-scaling mine pipe and a preparation method thereof belong to the technical field of mine pipes. Background technique [0002] Mine beneficiation water contains a large amount of metal cations, non-metal anions and solid particles, as well as flotation agents, flocculants and other agents, which are easily combined with each other during the transportation process to produce insoluble precipitates, which are easily adsorbed on the inner wall of the pipeline , resulting in an increase in the pressure of liquid delivery, because it is easier to attract new sediment at the place where scaling occurs, and over time, it will cause serious blockage of the pipeline. [0003] In the prior art, fluorine-containing polyolefin materials are often used to attach fluorine-containing polyolefin materials to the inner wall of the water delivery pipe to reduce the adsorption of the inner wall to the sediment and further reduce the possibility of clogging.

Over time, it will cause serious blockage of the pipeline

[0003] In the existing technology, fluorine-containing polyolefin materials are often attached to the inner wall of the water delivery pipe to reduce the adsorption of the inner wall to the sediment and further reduce the possibility of clogging. Very easy to wear, resulting in loss of anti-fouling function
