Which type of anti-corrosion coating is used in cast iron radiators for corrosion protection, and anyone who is familiar with coating protection knows that the effect of coating protection is determined by both the level of the coating and the quality of the coating. For the radiators, the corrosive conditions for the operation of the project are relatively harsh, and the importance of the coating quality is more pronounced. There are many radiator manufacturers in China who do anti-corrosion coating on the radiators, but there are great differences in the level of coating. The Tianjin Radiator Factory is broadly divided into the following four types:
1. No surface degreasing and rust removing treatment for cast iron radiators before painting;
2. Although internal anti-corrosion is done inside the radiator, it can be done well. However, in many aspects such as technology, equipment, and management level, there are still bodies in some links that can pass the inspection, but the quality of internal corrosion is not Fully assured that, in the case of poor water quality, the service life of the radiator product will not be long;
3. High degree of emphasis on internal corrosion, complete equipment, use, operation, strict management, internal anti-corrosion quality can withstand inspection, for a variety of boiler water, water quality can be effective anti-corrosion, ensure the service life.
4. Although cast iron radiators have done internal corrosion, they also want to do well, but the technology, equipment and management are limited, and the quality of internal corrosion does not meet the requirements. It is difficult for radiators to pass the dynamic loop test of internal anti-corrosion coating level. The service life of the radiator is greatly affected.
