Water-soluble aluminum flux can be used together with the aluminum based brazing filler materials to braze aluminum and aluminum

Aluminium welding flux powder:

Availability	Water-soluble aluminum flux can be used together with the aluminum based brazing filler materials to braze aluminum and aluminum alloy, using manual torch brazing and automatic torch brazing
Physical description	White powder, granularity ≤ 150 um, density: 1.3-1.4 g/cm3.
Components	Alkali metals, alkaline-earth metal chlorides, fluoride, and active agent.
Standard	JB/T6045-92, Fluxes for Brazing, Zhuang, Hongshou
Packaging	500 g/box, 20 kg/carton, 500 g/bag, 40 kg/carton, 30 kg/drum, 250 g/box, 20 kg/carton.
Operation	In advance, properly place the brazing filler metal on the brazing joint which will be heated together with the work pieces. In the process of manual torch brazing, firstly, the brazing wire needs to be tipped with the flux Then, after the work pieces are heated to the brazingtemperature,the brazing wire is manually handled to keep close to the brazing joint. The wires are evenly heated by the outer flame from the Multiple-holesbrazing torch, To protect the metallic materials, the flame should be placed at the proper distance away from the wires to avoid the oxidation of the work pieces, producing high-quality brazing seams.
Preparation	In advance, properly place the brazing filler metal on the brazing joint which will be heated together with the workpieces. In the process of manual torch brazing, firstly, the brazing wire needs to be tipped with the flux. Then, after the work pieces are heated to the brazing temperature, the brazing wire is manually handled to keep close to the brazing joint. The wires are evenly heated by the outer flame from the Multiple-holes brazing torch, To protect the metallic materials, the flame should be placed at the proper distance away from the wires to avoid the oxidation of the work pieces, producing high-quality brazing seams.
Post treatment	The residue of the Water-soluble Aluminum Flux attached on the work pieces is corrosive which should be cleaned timely.
Several methods of post treatment
1. Scrub the joint in the water with 50-60C. 2. Complicated work pieces can be merged into cold water after the solidification of the filler metal. The residue can fall off the surfaces because of thesudden boiling of water. Partial component in the residue can be dissolved into the water. In this method, the temperature difference between the cold water and the work pieces should be cautiously controlled to prevent the shaping and cracking of the work pieces. 3. Use 30 g/l concentrated oxalic acid, 15 g/l concentrated sodium fluoride, and 30 g/l concentrated #601 detergent water solution washing. Keep the temperature to be 70-80C. 4. Use phosphoric acid with volumetric fraction of 5%, and chromic anhydride water solution with 1% mass concentration to wash at 82C. 5. After being dipped in hot water, merge the work pieces in to the nitric acid with volumetric fraction of 10% and hydrofluoric acid with volumetric fraction of 0.25% for 2-3 min.

Q:How does ethyl cellulose act as a large particle binder: Ethylcellulose (DS: 2.3-2.6) The most commonly used mixed solvents are aromatic hydrocarbons and alcohols. Aromatic hydrocarbons can be benzene, toluene, ethylbenzene, xylene, the amount of 60-80%; alcohol available methanol, ethanol, the amount of 20-40%.

Q:Motorcycle cover rotten, I want to stick back, to be fixed in the car, twisted screw, what glue can be completely sticky tight? I used 502 with a few days and rot: China City Ruite Adhesive Co., Ltd. is specialized in the adhesive industry, is set research and development, production, sales and service in one of the professional adhesive company. And customers in the production of bonding problems encountered in the application of electronic and chemical problems to provide a reasonable solution, according to customer needs to provide a variety of suitable for the production process of the program, adhesives and adhesives products. Is a professional research and development, production, sales of adhesives, sealants and other adhesive products company.

Q:Adhesive 252 on the human body what harm: The main hazards of formaldehyde is the stimulation of the skin and mucous membranes, formaldehyde is the raw material, can be combined with the protein, high concentrations of inhalation occurs when the respiratory tract irritation and edema, eye irritation, headache.

Q:Preparation of white latex formula and production process: White latex is a water-soluble adhesive, is a vinyl acetate monomer in the initiator under the action of polymerization and made a thermoplastic adhesive. Usually add titanium dioxide (low-grade on the addition of calcium, talc, powder) .After the emulsion polymerization made of milky white thick liquid.

Q:Characteristics and Uses of General Purpose AB Adhesive: The market are generally acrylic type, in fact, many glue can be ab glue, such as epoxy, polyurethane, silicone and so on.

Q:The basic properties of sealant: And other media low penetration;

Q:What is the difference between paint and adhesive? Paint and adhesive test questions die ,,, worship.: Hard, I am looking for, tomorrow's exam. The

Q:I can not tell - Adhesive Adhesive Sealant Coatings and other chemicals, what are the same and different?: Paint, also known as paint. Refers to the surface of the object under certain conditions can form a film and protect, decorate or other special features (insulation, rust, mildew, heat, etc.) substances. There are three main points: the protection, decoration, and cover up the product defects, enhance the value of the product

Q:Polyurethane sealant: , One-component polyurethane sealant (paste) is a solvent-free one-component room temperature curing sealant. The sealant is creamy and can be extruded or applied. There is anti-drooping, embedded vertical joints and the top seam is not flowing. The cured layer is rubbery and elastic. Of the metal, rubber, wood, cement components, ceramics, glass and other adhesives. Sealant is used to fill the gap (holes, joints, joints, etc.) of the material, both the bonding and sealing two functions.

Q:New feed additives is not only a unit or individual declaration, they declared other units can not be declared after the declaration?
