The invention relates to a method for preparing tungsten carbide abrasion resistant composite coating by a penetration brazing method, belonging to the field of coating preparation in materials processing engineering. The invention comprises the following steps: (1) pasting coating metal powder cloth containing tungsten carbide-cobalt (WC-Co), nickle (Ni) and chromium (Cr) mixed powder on a metalsubstrate by using epoxy resin bonding agent; (2) preparing welding material metal powder cloth from BNi-2 brazing material and pasting the welding material metal powder cloth on the coating metal powder cloth obtained in the step (1); and (3) carrying out penetration brazing in a vacuum furnace to form a metallurgical bonded interface. The tungsten carbide abrasion resistant composite coating can be applicable to protection of mechanical elements in the field of generating plant, petroleum, aviation, food, plastics and the like.

The invention relates to a special metal flexible cloth for the preparation of a coating with high temperature and corrosion resisting and a preparation method thereof. The metal flexible cloth can be used for the protection of mechanical parts in fields, i.e. a power station, petroleum, aviation, food, plastic, and the like. The metal powder cloth is prepared by adding a forming agent and a bonding agent into the mixed power of metals, i.e. WC-Co, Ni, Cr, and the like, and the cloth patch can be bonded on a metal base body by an organic bonding agent to form a thicker protective layer with abrasion resistance, high temperature resistance and corrosion resistances by being metallurgically combined with the metal base body in a penetration brazing way. The coating has good heat conductivity, corrosion resistances and impact resistance, and wrapped parts can recover the original mechanical property of base materials through heat processing, thereby, the costing can be suitable for the recovery of pieces with heterogeneous surfaces and especially suitable for the recovery of a curved surface, a folded surface, a helical surface, and the like. The invention an solve the problems of the high temperature corrosion and the abrasion of parts with serious abrasion and heat resistance in mechanical equipment and power station equipment, decreases the times of stopping production for overhauling and enhances the economic benefits.

Disclosed is a paper printing method for fibrous and leather materials characterized by having: a step wherein printing paper is obtained by applying a mixed paste comprising a water-soluble synthetic binder, a natural adhesive, and an auxiliary agent to base paper, which is then dried to obtain paper for printing, onto which a dye ink is printed; a step wherein the printing paper is bonded to a fibrous or leather material and fixed using pressure / heat; and a step wherein the printing paper is removed after a dye fixing process is carried out while the printing paper is fixed to the fibrous or leather material. Further disclosed are the paper for printing and the printing paper used in the paper printing process, and the fibrous and leather materials characterized by being printed on in the paper printing process.

The invention discloses a static even-color painting method comprising the following steps of: setting a painting chamber control unit for controlling air speed in a painting chamber; setting a static automatic painting unit for controlling the working state of a static automatic painting gun to ensure that the static automatic painting gun achieves a set painting effect; setting an automatic hanger unit to ensure that workpiece hangers to be painted are reasonably arranged at intervals and the velocity of conveying chains for suspending the hangers are reasonable; and painting workpieces to be painted, hung on the hangers in the painting chamber by using the static automatic painting gun so that paints are attached to the workpieces well by a static effect. The static even-color paintingmethod has the advantages that (1) a paint film has the characteristic of evenness, good leveling property and obviously improved orange-peel phenomenon; (2) the distinctness of image (DOI) and glossiness of the paint film are improved, and a PGD (a unit of the DOI) value can be improved by 0.1-0.3; (3) by adopting static automatic painting, the emission of a volatile organic solvent is effectively reduced to relieve environmental pollution of painting; and (4) the painting efficiency is improved and paint is saved.

The invention discloses a plastic container, a long flow member and a coating apparatus, being able to avoid the harmful condition that the flow path of the viscous liquid is closed when the plastic container body is shriveled, and to eliminate the condition that the viscous construction member adhered to the pipe when the pipe is repeatedly used so as to pollute the surrounding. The plastic container comprises a plastic container body which is provided with an opening and is filled with the viscous liquid and has flexibility so as to help the viscous liquid ejected from the opening when the container is shriveled by compression, a long flow member which extends to the inside of the plastic container body and arranged at the opening, wherein the ejection flow path at least beginning with the side surface formed when the viscous liquid is ejected is taken as the ejection flow path of the viscous liquid; and when the plastic container body is shriveled by compression, the shriveled plastic container and the long flow member can be deprecated together.

A stabilized fluorine-containing polymer powder having an average particle size of 5 to 100 μm is prepared by contacting a fluorine-containing polymer powder, which is prepared by milling the fluorine-containing polymer and removing fine particles, fibrous particles and coarse particles by classification, with a fluorinating agent so that the total number of unstable terminal groups is decreased to 7 to 50 per 106 carbon atoms. This is a fluorine-containing polymer powder achieved a high coating efficiency in an electrostatic coating method and provides a film having good properties such as heat resistance, non-tackiness, low frictional property, chemical resistance, etc.
