Problems solved by technology

[0004] In order to reduce the joints connecting engineering pipelines, the transmission pipeline has to meet the specification requirements of a certain length, but the existing technology and equipment for preparing laminated flat glass have strict restrictions on the length of the prepared products, which is not suitable for the production of interlayer transmission pipelines
[0005] In addition, the existing method of producing laminated flat glass adopts the operation of edge sealing and swing method or vacuum kettle method to remove the air bubbles in the middle layer. The operation of air removal is not only cumbersome, inefficient, but also unstable in quality
The swing method is to use the buoyancy of the bubbles in the prepolymer and the centrifugal force that rises with the swing of the entire flat glass to be eliminated. It is not easy to get rid of the viscous slurry; the vacuum kettle method not only vacuumizes the middle layer, but also requires the entire space in the vacuum kettle to reach a certain degree of vacuum, so it takes a long time for vacuuming and consumes a lot of energy.
[0006] The process and equipment for preparing laminated flat glass by the existing method cannot eliminate the curing exotherm or heat the curing in time, and the curing of the prepolymer requires a strict "temperature-time" system to improve the curing quality of the intermediate layer

Abstract

The invention discloses a laminated inorganic pipeline and belongs to the technical field of pipeline transportation. The laminated inorganic pipeline comprises a first-diameter pipeline body and a second-diameter pipeline body with different diameters. The first-diameter pipeline body is sleeved with the second-diameter pipeline body to form the laminated inorganic pipeline. A central hole is formed in the first-diameter pipeline body. An interlayer is formed between the first-diameter pipeline body and the second-diameter pipeline body. The interlayer is filled with slurry, and the slurry solidifies to form a polymer middle layer. The slurry comprises a prepolymer and inorganic modified powder. The mass ratio of the prepolymer to the inorganic modified powder is 1:(0.01-3.0). The invention further discloses a preparation method for the laminated inorganic pipeline. According to the laminated inorganic pipeline, the inorganic modified powder is added into the prepolymer, and the mechanical property is remarkably improved; the prepolymer can aggregate and solidify in a more accurate and more stable environment, and the solidification quality is improved; and the preparation method provided by the invention is simple in process, easy to apply and popularize, and quite good in practicability.

Description

technical field [0001] The invention belongs to the technical field of pipeline transportation, and in particular relates to a sandwich inorganic pipeline and a preparation method thereof. Background technique [0002] Metal pipelines are widely used in the field of transportation technology, but the corrosion resistance of metal pipelines is not as good as that of inorganic materials, especially in the occasions of transporting highly corrosive liquids, gases and powders, while inorganic material pipelines can transport hydrofluoric acid and Any corrosive substances other than hot phosphoric acid; some metal pipes containing heavy metals will also pollute the conveying objects, while inorganic material pipes will not; however, inorganic materials are brittle, such as glass pipes are well-known representatives of typical brittle materials, The impact resistance is poor, and the medium pressure resistance does not exceed 0.6MPa, which limits its application in the pipeline tr...
