Zinc-iron steel rapid phosphating solution technology, steel oil and rust removal two-in-one technology

Zinc-iron steel rapid phosphating solution technology
The energy-saving and environmentally friendly zinc-iron rapid phosphating solution developed by the surface treatment expert group of Beijing Huaxia Keyuan Technology Development Center is suitable for automobiles, motorcycles, agricultural vehicles, bicycles, Phosphating treatment before painting of all metal products such as household appliances. It can be used in baking, spray painting, plastic spraying, electrophoresis and other processes.
Ultra-speed and ultra-low temperature phosphating can work as usual at sub-zero temperatures. You only need to put the workpiece into the phosphating solution for a few minutes and take it out to dry. It has a long service life, and each kilogram of concentrated liquid can phosphate approximately one square meter.
Convenient management does not require surface adjustment, passivation, or acid ratio control, and only requires the appropriate addition of concentrated solution when the working fluid is scarce. The typical process flow is to use two and one degreasing and rust removing water washing, phosphating and drying as the next step. Extra large workpieces can be brushed and phosphated, and the phosphated coating will have good adhesion.
Working fluid concentration () is one kilogram of concentrated liquid mixed with one kilogram of water. Value. Add kilograms of water to the tank and then add kilograms of concentrated liquid and mix well. The value of the working fluid needs to be controlled during use. The comprehensive cost of each ton of concentrated liquid is about RMB 1,000, and the market price is more than RMB 1,000.
Notes: The oil stains on the workpiece must be removed before phosphating. Remove debris from the tank regularly.
Technical service method: The technology transfer training fee for this project is RMB 1,000, including factory technology, on-site training, and learning. The investment in equipment is RMB 1,000. The main equipment is a reactor or a homemade mixer. Production personnel, square meters of factory building. Raw materials are readily available everywhere.

Steel oil and rust removal two-in-one technology
One product overview
Produced by surface treatment experts from Beijing Huaxia Keyuan Technology Development Center The steel rust and oil removal two-in-one product developed by the team has strong rust removal ability and fast oil removal speed. It is suitable for pre-treatment of various steels in electroplating, electrophoresis, phosphating and painting, and the effect is excellent. The two-in-one oil and rust remover is a product that combines oil and rust removal. It is formulated with rust removal aids, penetrants, surfactants, etc. It is basically non-corrosive to steel, iron and other products, non-combustible and does not contain heavy metals and other substances. It has the function of removing rust from the oxide layer, descaling and degreasing in one pass. It can effectively increase the cleaning speed and can completely remove rust in minutes. It traces the dissolution, dispersion and peeling off of oxide scale from the surface of the steel matrix without causing excessive corrosion and hydrogen embrittlement.

3. Application scope
Pipe wall rust removal, metal parts degreasing and rust removal, rust removal of copper, copper alloys, etc., steel bars, pipe rust removal, Surface rust removal of engineering machinery, oxidation of hot-rolled parts and rust removal repair and maintenance projects for bridges, iron towers, mechanical equipment and facilities, ships, vehicles, and other precision instruments.
4. How to use
Dip cleaning method: Dilute the rust remover to 100%, then immerse the items to be rusted in the diluted cleaning solution. Remove the items after the rust and oil stains are clean. , rinse thoroughly with clean water and proceed to the next process.
, Wipe method: Use a brush to apply the rust remover on the surface to be removed, and apply it every few minutes. If you use water sandpaper or a rough wipe soaked in the rust remover to wipe it, the rust removal effect will be better. It is faster and more obvious. After the rust is removed, rinse it with clean water and then proceed to the next process.
Five production conditions
Factory building is square meters, workers. The equipment is a reaction kettle or a homemade mixer. The cost of the concentrate is RMB per ton, and the market price is more than RMB 10,000.
Six technical service methods
Technology transfer training fee is RMB 1,000, and factory-based technology is guaranteed to succeed. Provide raw material manufacturers.
7. Precautions
This product is non-toxic, non-polluting, non-flammable and safe to use.
Please wear latex gloves when operating. If you accidentally get it into your skin or eyes, please wash it off immediately with clean water.
. Plastic containers should be used when using this product.
After the cleaning fluid has been processed for a period of time, the active ingredients will be consumed. A certain amount of rust remover solution should be added, or when the color of the impurities in the cleaning fluid is too dark and the cleaning effect is poor, a new rust remover should be replaced. rust solution. Mix the concentrated liquid and water evenly in the liquid storage tank according to the ratio (volume ratio).
