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.

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.

Concrete crack treatment, refers to the scientific approach to the repair of concrete cracks in the technology. Concrete cracks generally have three states: static cracks, active cracks, is developing cracks. The choice of concrete crack treatment methods generally to consider the factors: to determine whether the cracks are active or static; repair the main purpose of what? Is to reduce the excessive leakage, so that the cracks at the complete water; whether the need for reinforcement treatment; crack the main reason is what; cracks in the future changes (value and direction) how. - 13 common methods of concrete crack treatment: 1. resin infusion method; 2. surface sealing method; 3. drilling insert method; 4. flexible sealing method; 5. surface additional reinforcement method; 6. grouting method; . Dry insert method; 8. nail method; 9. polymer immersion method (gravity infiltration and vacuum infiltration); 10. Die surface layer and surface treatment method and so on.
Q:Zhuang Code paint is China's top ten paint brand?
Hello, if you want to do paint agent, I suggest you choose China cherry, cherry paint is a first-line paint brand. From the environmental health index, cherry paint is a high-tech processing and produced a new type of environmentally friendly paint, the use of natural orange oil, linseed oil, tung oil and other vegetable oil as the main raw material, it does not contain benzene, Xylene and heavy metals, and toxic petrochemical raw materials as the main component of the paint composition is completely different!
Q:The 18th China International Adhesive and Sealant Exhibition published papers how to find
It is also an important step in the process of writing the essay, which can be said to have entered the formal writing stage. First of all, to the basic types of academic papers (common format) have a general understanding, and according to their own information to consider the composition of the paper form. For the beginner thesis writers can refer to the type of paper published in the magazine, to be aware of; secondly, to master the information to do further research, taking into account the choice of many materials and use, so that the argument is outstanding, reliable argument, , The various parts of the convergence of appropriate. Third, we should consider the outline of the outline of the outline. The outline of the thesis can be divided into two types: rough and sketch. The former only reminds the main points of each part, and does not involve the development of materials and papers. For experienced authors can be used. But for beginner thesis writers, it is best to propose a more detailed writing outline, not only put forward the various points of the paper, but also the material and materials involved in the detailed arrangements and the relationship between the various parts are Reflected, writing can be handy.

Q:Easily soluble in water
Alginate is slightly soluble in water and insoluble in most organic solvents. It is dissolved in alkaline solution, so that the solution is viscous. Sodium alginate alginate is hygroscopic and the amount of moisture contained in the equilibrium depends on the relative humidity. The dried sodium alginate is stored fairly stable in a well-sealed container at 25 ° C and below. Sodium alginate solution is stable at pH 5 to 9. The degree of polymerization (DP) and the molecular weight are directly related to the viscosity of the sodium alginate solution, and the decrease in viscosity during storage can be used to estimate the degree of sodium alginate de-polymerization. High degree of polymerization of sodium alginate stability is less than the degree of polymerization of sodium alginate. It is reported that sodium alginate can be catalyzed by proton hydrolysis, which depends on time, pH and temperature. The propylene glycol alginate solution is stable at room temperature at pH 3 to 4; when the pH is less than 2 or greater than 6, the viscosity will decrease even at room temperature. The sodium powder is wet with water and the hydration of the particles makes the surface sticky. The particles are then quickly bonded together to form clumps, and the agglomerates are slowly and completely hydrated and dissolved. Alginate is more difficult to dissolve in water if it contains other compounds that compete with alginate for hydration. Water in the sugar, starch or protein will reduce the rate of sodium alginate hydration, mixing time necessary to extend. A monovalent cation (such as NaCl) also has a similar effect at concentrations above 0.5%. The pH of sodium alginate in 1% distilled water was about 7.2....

Q:What is meat adhesive?
In simple terms, it is a food additive that binds meat. Used to bind meat or pieces of meat. A lot of beef and mutton manufacturers in the cutting of meat will have a lot of beef and mutton meat or some scrap, with meat adhesive can be the next sub-material into the whole piece of meat and then take the split, Lamb chops or beef slices lamb slices shabu hot pot and so on. Generally the whole piece of sticky meat does not have adhesive traces, and the heating generally does not crack.
