1. Uses
The agent is an inorganic binder used in solid-liquid dispensing made of phosphoric acid solution and special copper oxide powder. It is mainly used for the bonding of tools and gauges, repair of shafts, and plugging of castings and trachoma.
The agent has the characteristics of convenient operation, saving equipment, saving time and saving time.
2. Raw materials
( 1 ) Copper oxide: black powder, specially made, particle size of 200 mesh, acid and alkali materials shall not exceed 0.01% . It is made from copper sulfate and sodium hydroxide. It is one of the main raw materials of this agent, and it selects industrial products.
( 2 ) Phosphoric acid: Pure product is a colorless liquid, and the industrial product is a viscous liquid with a content of 83 to 98% . Soluble in water and ethanol. Corrosive to the skin. Can absorb the moisture in the air. Widely used, such as phosphate, glycerol phosphate, ammonium phosphate fertilizers. It is one of the main raw materials of this agent. Use industrial products.
( 3 ) Aluminum hydroxide: White monoclinic crystal. Typical amphoteric compounds. Insoluble in water and ethanol, soluble in hot hydrochloric acid, sulfuric acid and alkalis. Used for making waterproof fabrics, glassware, etc. Used as a buffer in this agent. To extend the life of the adhesive. Use reagent grade products.

4. Preparation method
(1) phosphate Chang Liao Gui wholesale  hollow brown ticket blessing? / P>
Was added in a container with 100ml phosphate, added 5 to 8 grams aluminum hydroxide, was heated to 220 deg.] C, stirring and mixing phosphoric acid Chang Liao Gui fans  hollow skeleton? / P>
( 2 ) Phosphorus phosphate Che Xia Lin Fu / P>
Take a certain amount of copper oxide powder and a certain volume of ( 1 ) solution, stir and mix and serve. The copper oxide powder and the phosphoric acid lanthanum lanthanum have a thickness of 5 to 5:1 , and the modulation is preferably performed on a copper plate with excellent heat dissipation. Care should be taken when preparing the filaments.
The agent is solid-liquid dispensing and is sold as an accessory.
5. How to use
( 1 ) Decontaminate and roughen the adherend surface.
( 2 ) With the use of adhesives.
( 3 ) Adhesion: Adhesive is applied to the adherend for bonding.
(4) Drying: After placing an adhesive into the oven for about 2 hours 60 ~ 80 ℃ bake for 2 hours before use and then after 36 hours curing.
