Specific introduction of casting coatings

Now many people should have heard of casting paint, which is a material for making abrasives. Now it will be used in many places. Although casting coatings are widely used, many people still don't know its function and application scope. Now follow us to see the scope of use and the use and method of casting paint!

First, the application scope and introduction of casting coatings

(1), the application range of metal contact surface, iron contact/aluminum contact/copper contact;

② Function 1, ZD coating can insulate heat, balance temperature and avoid the impact and corrosiveness of molten metal, thus protecting tools and prolonging their service life by more than 1/3; 2. To prevent the casting from cracking and white mouth formation caused by local cooling too fast; 3, the adsorption time is as long as 7 days, and the air permeability is good. Acetylene smoke treatment can be used instead of using release agent every time, and a casting can be smoked once;

③ Advantages: 1. Compared with phosphating film, its unique physical properties determine its advantages; 2. Good ventilation; 3. The heat preservation effect is obvious, and the melting point is above 1650℃; 4. After spraying, it has strong adhesion and is not suitable for peeling. Generally, it needs to be repaired after one week. ZD coating does not need to be sprayed every time it is opened like other coatings, which saves the tedious work of disassembling tools every day because of spraying coating; 5, the price is relatively low, which greatly reduces the expensive production and casting costs caused by the use of alcohol-based coatings or imported coatings; 6. Greatly improve the production efficiency.

(4) It is recommended to use the method of 100g coating powder+100g neutral sodium silicate +300g water, pour it into a small soymilk machine, fully mix it, then pour it into a spray gun, and spray it on the hot (200-300℃) metal mold surface, with a thickness of 0.2mm, and the local thinner parts can be sprayed for 0.3-0.0 according to product requirements. If there is any discrepancy, the manufacturer's requirements shall prevail!

Second, what is the role of casting coatings? What are the advantages of casting coatings?

1, ZD coating can insulate heat, balance temperature and avoid the impact and corrosiveness of molten metal, thus protecting tools and prolonging their service life, which can reach more than 1/3.

2, to prevent the local cooling too fast to cause casting cracking and white mouth formation.

3, the adsorption time is as long as 7 days, and the air permeability is good. Acetylene fumigation can replace the use of release agent every time, and a casting can be smoked once.

3. What are the advantages of casting coatings?

1. Compared with phosphating film, its unique physical properties determine its advantages.

2. Good ventilation.

3. The heat preservation effect is obvious, and the melting point is above 1650℃.

4. After spraying, it has strong adhesion and is not suitable for peeling. Generally, it needs to be repaired after one week. ZD coating does not need to be sprayed every time it is opened like other coatings, which saves the tedious work of disassembling tools every day because of spraying coating.

5. Relatively cheap, which greatly reduces the expensive production and casting costs caused by using alcohol-based coatings or imported coatings.

6. Greatly improve the production efficiency.

The above are the advantages of casting coatings and the specific introduction of casting coatings. I believe that you will have a certain understanding of casting coatings through the above contents. When using casting coatings, we should pay attention to choosing brands, and it is best to choose some well-known big brands, so as to ensure the quality of use and avoid other unexpected problems.
