The cleaning of 3pe anti-corrosion steel pipes generally adopts the "nitric acid, sulfuric acid, hydrochloric acid" system. If the surface quality of 3pe anti-corrosion steel pipes is high, a large amount of HF must be used, which is a serious environmental problem. At present, the technology and equipment treated with sodium sulfate have been introduced abroad to improve the rust removal and cleaning methods on the surface of 3pe anti-corrosion steel pipes.
The most representative is the high-tech product KL-3, which can be in contact with the skin when used, is harmless, does not produce toxic gas, does not need to be discharged, and is pickled and passivated in the same environment. Bath and pickling 3pe anti-corrosion steel pipe products have strong operability, simple management and operation, and low price. It has been used by many small and medium manufacturers in recent years.
It is well known that the use of surfactants to degrease grease, and phosphorus-free laundry detergents to degrease grease. Water and oil will be automatically separated, and the discharged liquid can only be discharged by neutralization. No strong acid, strong alkali, completely degreasing and rust removal, short time, strong ability to inhibit the penetration of acid mist. The working environment is more in line with environmental protection requirements, which can greatly improve the processing quality of 3pe anti-corrosion steel pipes and reduce production costs.
