Abstract: A pipeline demagnetization device based on a permanent magnet structure includes a central piece and permanent magnets distributed on the central piece. A magnetic field with alternating directions is formed in a wall of a pipeline in an axial direction from front to back, and strength of the magnetic field gradually decreases. The pipeline demagnetization device can be applied to the pipeline demagnetization using a built-in structure or an externally-built structure. The pipeline demagnetization device spatially constructs a set of stable alternately-decayed magnetic fields, so that the wall of the pipeline experiences the set of alternately-decayed magnetic fields when the pipeline that is magnetized spatially displaces relative to the set of alternately-decayed magnetic fields, thereby realizing demagnetization.

Abstract: The present invention provides a coalescing agent for aqueous coatings, a coalescing agent composition, and an aqueous coating. The coalescing agent for aqueous coatings is obtained by esterification reaction of fatty acids and glycol ethers. The coalescing agent prepared by the present invention has a boiling point as high as 330° C., has no irritant odor, and is environmental friendly and safe. It overcomes shortcomings of conventional coalescing agents, which is suitable for various polymer emulsion systems, and can significantly reduce the film-forming temperature of aqueous emulsion coatings and optimize the film-forming performance.

Abstract: Disclosed is a method of rearrangement of the molecular structure of isomers of TEXANOL, characterized in that two isomers in TEXANOL is subjected to rearrangement of the molecular structure at a certain temperature and pressure, and 2,2,4-trimethyl-1,3-pentanediol-3-isobutyrate and 2,2,4-trimethyl-1,3-pentanediol-1-isobutyrate in TEXANOL following the rearrangement are in a mass ratio of 31.81-38.65:60.80-67.65.

Abstract: An oriented bamboo strand board and method for manufacturing the same are provided. The method includes: (a) cutting a bamboo stalk (4) into sections (6), and splitting each section (6) into 3-12 arc bamboo blanks (8) in the radial direction; (b) removing a outer surface part (10) and inner surface part (11) of the arc bamboo blank (8) by a thicknesser; (c) flaking the bamboo blank after removal of the outer surface part (10) and inner surface part (11) into bamboo flakes (14) with a thickness of 0.1-0.3 mm in the chordwise or substantially chordwise direction; (d) applying glue to the bamboo flakes (14) after drying, and orientedly spreading. The bamboo flakes have large width, break-resistance, good flatten characteristic and easy glue application, and the mechanical strength of produced oriented bamboo strand board is 1.5-1.6 times as much as that of the oriented bamboo strand board manufactured by radial flaking.
