2. casting performance, or complex die-cast shapes, thin wall precision castings, smooth surface.

3. can be surface treatment: electroplating, painting, painting, polishing and grinding.

The melting and do not smoke when iron-casting, pressure-type non-corrosive, non-stick mold.

5. Have a good room temperature mechanical properties and wear resistance.

6. The low melting point, melting at 385 ℃, easy casting.

Use process issues to be aware of:

1. poor corrosion resistance. When the alloy composition of impurity elements such as lead, cadmium, tin than the standard time, resulting in deformation of casting aging, expressed as a volume swell, mechanical properties, especially ductility decreased significantly, a long time or even rupture. Lead, tin, cadmium zinc alloys solubility is very small, and therefore focused on the grain boundaries become the cathode, aluminum-rich solid solution of an anode, in water vapor (electrolyte) presence of conditions to foster intergranular electrochemical corrosion. Casting due to intergranular corrosion and aging.

2. Organization of aging effect of zinc alloy mainly containing Al and Cu, Zn-containing zinc-rich solid solution and Al-rich solid solution formed, their solubility decreases with temperature drop. However, due to the solidification casting speed is extremely fast, and therefore to room temperature, the solubility of solid solution is substantially saturated. After a certain time, this over-saturation phenomenon will gradually lifted, leaving the cast to shape and size slightly to change.

3. zinc alloy die castings should not be used at high temperature and low temperature (0 ℃ or less) work environment. Zinc alloy at room temperature have good mechanical properties. But at a high temperature impact properties were significantly decreased under tensile strength and low temperatures.

Corrosion of metal plate production process

Corrode metal plate is also called etching plate. The main search using the mask, after etching process processing system to do three steps from the Braille metal plate or a concave metal plate.

Corrosion of metal plate production process:

1) Cutting: by drawing (layout size) in size, surrounded by more than plus not less than 5mm burrs. Shears with 720 foot-operated shears, the surface smooth, surrounded by non-Maori.

2) metal corrosion signs Finish:

(1) mechanical polishing: polishing machine with 2.2-4 kW of mechanical polishing wool, cloth round use motor speed is generally 300-350 2000-3000 revolution / min.

(2) alkali treatment: 10-15% aqueous solution of sodium hydroxide at 65-85 ℃ in the metal plate cook 10-30 seconds, and then washed with water, immersed in 5% of the weight of Ming acid aqueous solution.

(3) powder processing method: using a flat brush dipped in old powder (double pink) version of the child will be a uniform method of cross brush ears, except to effect until decontamination face, skin or remove oxygen, and then with a 5% aqueous solution of potassium dichromate In closed.

(4) The drawing processing method: using mechanical or manual drawing methods were brushed metal plate surface treatment, metal surface regeneration to achieve the effect.

What is the metal flat sun signs

Metal flat sun signs sun cards mainly use photosensitive way, the film which was dissolved in different colors to make it through the development of methods was significant in the metal plate, so as to achieve a metal plate with a descriptive sense of purpose.

Here are some frequently come into contact with the metal flat plate concrete drying process and formula (flat sun signs, the process):

Flat aluminum plate sun: is the use of photographic plate method, the different pigments into the film inside, so that text, graphics presented in a metal plate, so as to explain the significance of having a metal plate.

1) material: wool size requirements are generally larger than the plate size (5mm or more), the board smooth, without potholes.

2) Pre-treatment: ① several ways polishing process ② ③ ④ drawing oxidation.

3) Water closed: will handle good board, through to oil, except after the film can not be quickly immersed in water and exposed to the air.

4) glue: glue configuration. Plastic: 200-230 grams of water: 1000ml, added photosensitizer (weight casein, ammonium) boiling water and cook for 2 hours to fully dissolve the glue, the temperature dropped to 30-50 ℃ 25-30 grams after glue evenly coated in metal plate, drying stand.

5) copy: You can use SB750 vacuum type machine photographic copy copy, light 60-90cm classification when signs comprehensive analysis
