Abstract

The invention discloses a ceramics particle strengthened composite material lining metal tube and a manufacturing method thereof, belonging to the field of composite wear-resistant tubes. 4,4-Diphenylmethane diisocyanate (MDI), polyester glycol, 1,4-butanediol (BD), ceramics particles and the like serve as raw materials to prepare composite material liquid castables, and a centrifugal casting technology is adopted to cast polyurethane base ceramics particle strengthened composite material lining layers on the inner wall of an outer thimble. The invention has the beneficial effect that the prepared ceramics particle strengthened composite material lining metal tube has excellent abrasive resistance and corrosion-resistance and greatly improves service life. The raw materials of the invention are easy to be obtained, manufacturing technology is simple, cost is low and economic benefit is obvious and practical application and mass production are beneficial for factories.

Description

technical field [0001] The invention relates to a composite wear-resistant pipe. Specifically, the invention relates to a ceramic particle reinforced composite material-lined metal pipe and a manufacturing method thereof. In particular, it relates to the manufacturing process of the metal pipe with the polyurethane-based ceramic particle composite material as the inner liner. Background technique [0002] In various industries such as mining and metallurgy, there are many processes such as pit backfilling, mineral transportation, waste treatment, sand excavation, ore cleaning, coal ash transportation, etc., which require long-distance transportation of large amounts of solid materials or mixed solid-liquid slurries , These materials or slurries contain a large amount of high-hardness lumpy or granular solids, so the corresponding conveying pipelines are facing serious wear problems. In these industrial applications, not only the strength and toughness of the pipeline are r...
