A component (20, 22) and method for a casting process, typically for cold-process casting of concrete wall, floor, ceiling or other panels or element in situ in building construction, leaving embedded in the cast panel a fastening surface (24) which can be adjustable to allow correction of non-uniform cast surfaces. The component may be integrated to conventional form-tie systems which use ties to space removable / reusable forms, holding forms a set distance apart, and can also hold a barrier material (typically expanded foam insulation) against the inner surface of a form(s) while casting is underway; when the forms are removed, leaving a component embedded providing an adjustable surface suitable for attaching material such finishing sheet material. The component can allow adjustment of its mounting surface with respect to the cast surface and to other like components in the cast panel to provide for (substantially) uniform surface for mounting finishing materials and / or fixtures.

The invention discloses a titanium dioxide-hydroxyapatite gradient coating of a medical titanium or titanium alloy surface and a preparation method. The inner layer of the titanium dioxide-hydroxyapatite gradient coating is a composite layer of the titanium dioxide and the hydroxyapatite while the outer layer of the titanium dioxide-hydroxyapatite gradient coating is a hydroxyapatite coating. The preparation method comprises the following steps of: using titanium or titanium alloy as anode and metal stainless steel as cathode; carrying out microarc oxidation on the titanium or titanium alloy by using a direct current pulse power supply; after forming a porous structure containing titanium dioxide and amorphous calcium and phosphorus on the surface of the titanium or titanium alloy, coating the hydroxyapatite on the surface; and finally obtaining the titanium dioxide-hydroxyapatite gradient coating. The porous structure formed after the microarc oxidation is beneficial for improving the bonding strength of a titanium or titanium alloy substrate and the costing; the titanium dioxide layer formed by the microarc oxidation has a transitional effect on the performance so that the residual stress between the substrate and a hydroxyapatite bioactive coating can be reduced. The preparation method has the advantages of simplicity and convenience in operation.

The invention provides a production device of fiber color points and a spinning method of color point yarns, and improves the common cotton spinning machinery, i.e. adding a cotton feeding system on various carding machines, simultaneously being dispensed with a cotton stripping device, installing a stripping and conveying device, configuring all the technological parameters (e.g. transmission rate, cutting die, doffer space and the like) of the carding machines, and being reformed into a device capable of producing various fiber color points. The spinning method utilizes the production device, selects the kind and the dosage of an adhesive suitable for the fiber to produce color points with different size specifications, different tightness and extensive color change according to different fiber types during the production process of the color points.

The invention relates to the technical field of heat treatment quenching, and discloses a quenchant for medium carbon alloy steel abrasion-resistant material. The quenchant comprises, by weight, 6% to 8% of sodium hydroxide, 6% to 8% of zinc chloride, 1% to 5% of sodium chloride, 0.01% to 0.03% of sulfonated castor oil, 0.01% to 0.05% of antifoaming agents, 0.1% to 0.5% of soap, 0.1% to 0.4% of preservative, 0.1% to 0.5% of antirust agents, 0.1% to 0.5% of lubricants, 0.1% to 0.5% of sterilizing agents and the balance water. The quenchant is reasonable in formula, and a quenched piece can have high hardness and is even in hardness. Sodium hydroxide and oxide skin on the surface of the quenched piece can interact with each other to generate hydrogen, so that the oxide skin can be rapidly peeled off, and the surface of the quenched piece can be in a shining silver color. Zinc chloride and sodium hydroxide react to generate strong zinc oxide, and the cooling speed of a high temperature area is higher than the cooling speed of water while the cooling speed of a low temperature area is lower than the cooling speed of water, so that deformation of the quenched piece is small, the quenched piece is not prone to cracking, and the surface of the quenched piece is shining.
