The invention discloses a waterproof antiseptic wearproof nano paint, a preparation method, a use method and application thereof. The paint has a middle layer, a surface layer or a bottom layer, a middle layer and a surface layer outwards orderly from the contact surface of a metal substrate surface; each layer comprises components by weight percent: the bottom layer comprises 10% to 25% of epoxysolution, 10% to 25% of polyamide solution, 50% to 78% of zinc powder and 2% to 10% of ferrous phosphorus powder; the middle layer comprises 15% to 30% of epoxy solution, 10% to 28% of polyamide solution, 42% to 70% of micaceous iron oxide, 2% to 10% of ferrous phosphorus powder and 2% to 8% of talcum powder; the surface layer comprises 25% to 50% of modified epoxy resin solution, 20% to 44% of polyamide solution, 5% to 20% of carborundum, 0.5% to 3% of nano carborundum and 10% to 25% of alumina and proper defoaming agents are added respectively to each layer of paint. The paint largely enhances the waterproof, antiseptic and wearproof performance of substrate, largely prolongs the service life and has good market prospect and practical popularization value.

The invention relates to a metal surface cleaning solution which is prepared by following raw materials of, by weight percentage, sulfuric acid, hydrochloric acid, a high polymer composite enhanced active agent, sodium dodecyl benzene sulfonate, urotropin, sodium silicate, citric acid, urea, industrial salt, triethanolamine and water. The cleaning solution can completely clean up various greasy dirt, rust and scale cinder attached on a metal surface effectively, and protective film can forms on the metal surface after being cleaned so as to prevent metal from rusting and oxidizing in a certain period. Waste water of a used cleaning solution can be reused after being recovered, precipitated and filtered.

The invention discloses micro-emulsified water-soluble cutting fluid and a preparation method thereof. The micro-emulsified water-soluble cutting fluid comprises the following components in percentage by weight: 6-15 percent of base oil or oiliness agent, 2-5 percent of nonionic surfactant, 5-10 percent of anionic surfactant, 5-8 percent of mixed alkylol amine, 10-15 percent of antirust agent, 0.08-0.1 percent of copper alloy corrosion inhibitor, 0-0.5 percent of ethylenediamine tetraacetic acid tetrasodium salt, 0.1-0.2 percent of antifoaming agent and the balance of water. The micro-emulsified water-soluble cutting fluid prepared by the invention is high in cooling property, antirust property and hard water resistance and hardly deteriorates or stinks, the product can inhibit fungi, bacteria and moulds very well without adding any special bactericide, the service life of the product is prolonged, and harm of the bactericide to skin irritation is avoided. The cutting fluid is reasonable in formula, multiple surfactants and aids are utilized, the provided cutting fluid is diluted with water according to a general ratio of 1:20 before being used, the antirust time of a single product exceeds 180 hours, the use of the product is not influenced even if the tank is not replaced within a year according to customer response, the manpower and material resources needed in the process of replacing the tank are saved, and the cost is saved.

The invention relates to flux core powder for manufacturing a seamless self-shielded welding wire. The skin of the seamless self-shielded welding wire adopts a mild steel strip, and the flux core powder is synchronously added to the mild steel strip on line. 100 parts of flux core powder comprises the ingredients: 35-50 parts of barium lithium fluoride, 3-5 parts of magnesium fluoride, 0-4 parts of sodium fluoride, 1-3 parts of calcium fluoride, 4-12 parts of iron oxide red, 1-3 parts of rare earth fluoride, 4-8 parts of metal manganese, 10-18 parts of aluminium magnesium alloy, 6-10 parts of metal nickel, 0.5-2 parts of metal zirconium, and the balance of iron powder. All the materials are mixed and stirred uniformly according to a customary method, so that the flux core powder is obtained; the mild steel strip is curled to form a linear seamed cylinder by roller molding, and the linear seamed cylinder wraps the flux core powder; the linear seamed cylinder is manufactured into a semi-finished product seamless self-shielded welding wire by using high-frequency induction or contact bond; the semi-finished product seamless self-shielded welding wire is subjected to annealing and reducing, and is subjected to copper plating, and then the seamless self-shielded welding wire is prepared. In order to prevent the flux core power from absorbing moisture, the skin can be subjected to copper plating, and thus, the rust resistance of the seamless self-shielded welding wire is improved.

The invention provides a nanometer zinc phosphate antirust pigment continuous production method and device. Zinc oxide and phosphoric acid are used as raw materials, under the synergistic effect of multiple auxiliaries such as a template agent and a dispersing agent, the contact reaction surface between zinc oxide and phosphoric acid is continuously updated by means of three-level serial grinding, particle shape and size control is conducted, and nanometer zinc phosphate antirust pigments with a uniform particle size are obtained by means of dehydration, spray drying, modification and smashing. Full-automatic control is adopted, production is convenient and fast, the obtained nanometer zinc phosphate antirust pigments are uniform in particle size and stable in product quality, and the antirust performance is improved by 20% compared with existing imported zinc phosphate.
