First, aluminum silver paste introduction:
Aluminum silver paste belongs to category 33646: paints, auxiliary materials and coatings containing secondary flammable solvents
The aluminum silver paste is mainly composed of aluminum powder, solvent and auxiliary agent.
Aluminium silver paste is a kind of pigment. It is specially processed and surface treated, so that the surface of the aluminum sheet is smooth and smooth, the edges are neat, the shape is regular, the particle size distribution is concentrated, and the matching with the coating system is excellent.
Aluminum silver paste can be divided into two types: floating type and non-floating type.
The shape of the aluminum sheet is divided into: snowflake shape, fish scale shape and silver dollar shape.
The first type: floating silver paste floats on the surface of the coating film due to its low surface tension, and has extremely high light reflectivity and plating effect, but the aluminum sheet is easy to fall off from the surface of the paint film, causing difficulty in recoating, and is applied to anticorrosion and roofing. , tanks and other occasions;
The second category: non-floating silver paste can be completely wetted by the coating, evenly distributed throughout the paint film, and has a tendency to sink. The film is solid and stable, and can be recoated with a large amount of light. Furniture, electronics, coils, etc.
Second, the use of aluminum silver paste:
Aluminum silver paste is widely used in: automotive paint, motorcycle paint, bicycle paint, plastic paint, architectural paint, ink, mobile phone casing and buttons, electromechanical casing, electric casing, metal paint, and many other fields, but insoluble in water-based paints. Silver paste is a solvent type.
Aluminum silver paste is mainly used in: automotive coatings, weak electrical plastic coatings, metal industrial coatings, marine coatings, heat-resistant coatings, roof coatings, etc.
Third, screening mesh and configuration:
1. Screening mesh: 150 mesh, 200 mesh, 325 mesh, 400 mesh, 500 mesh
2. Material characteristics: flammable and explosive (dangerous goods)
3. Screening purposes: mainly grading; equipment is generally one layer, one mixing tank is equipped with 3 sieving machines, the relative screening requirements are relatively high, and the requirements for screens are very strict (uniform aperture, silk).
4. Model and configuration:
M800 vibrating screen 1S-Q235A is galvanized,
4.1. The grid is adopted: solid mother grid; screen: military 540 factory
4.2. Seals, marbles material: polytetrafluoroethylene; block ball material: nylon
4.3. At present, more carbon steel is used for galvanizing (the purpose is to prevent the surface of the painted paint from falling off after encountering 200# solvent oil to prevent the pollutant material), but now the benchmarking enterprise has adopted the contact material stainless steel material (convenient to clean and beautiful)
4.4. The excitation source is divided into two types: explosion-proof motor and vibration motor. It is generally recommended to recommend the explosion-proof motor to the customer. The first consideration is safety, the second is in line with the national standard, and the motor angle is the best: the motor is reversed.
