Screw thread steel There are many rust removal methods, but you can try chemical or physical rust removal methods to save costs. No trace of treasure building rust one Type is a very good one rust remover 。 Chemical derusting is to use rebar derusting agent and spray it on the rebar surface. If the corrosion is serious, immersion method can also be used for derusting. However, from the perspective of cost saving, this method is suitable for the case of small amount of rebar. If the amount of rebar is large, you can use the physical rust removal method of rebar deruster to save costs!
The corrosion treatment of steel is metal surface treatment Although many kinds of products have been launched in the domestic and foreign markets, there are some problems with the process. Beijing Zhubao Company has developed a new generation of metal rust remover with imported raw materials in accordance with the defects of existing rust removal products and the development needs of production processes for rust removal and environmental protection ——Rust Traceless Type 1 。 No trace of rust Type 1 It is a multifunctional metal rust remover at normal temperature, Unique formula, Inclusion Acid in agricultural production system and multiple permeation, catalysis, corrosion inhibition, etc auxiliary , can be completed in one step Oil removal, rust removal, short-term rust prevention process, It represents the R&D direction and advancement of the market, and is a technological breakthrough to traditional derusting products.
The current situation that there is a demand for rebar rust removal on the site is that the rebar cage is basically bound for rust removal. In this case, a simple way to save labor and material costs is to spray rebar rust remover. If it is a whole bundle of rebar rust removal, it is necessary to build a pool, pour rebar rust remover, soak rebar in it, and constantly add liquid medicine, Ensure the concentration and effect of rebar rust remover. Good rebar rust remover does not contain a drop of hydrochloric acid and does not corrode rebar accelerator Stripping agent, relieving agent, agricultural production system acid ( Phytic acid and edible phosphoric acid ) , surfactant, etc. Through chemical reactions such as penetration, absorption, transformation and renewal of the rust layer on the steel bar surface, the rust is transformed into a dense zinc iron phosphate compound salt in coordination with each other, and the salt is finally solidified into a waterproof, rust proof neutral high corrosion resistant chemical conversion film ( Taupe ) , firmly solidified on the surface of reinforcement, can significantly improve the grip strength of reinforced concrete and the bonding strength of concrete, effectively reduce and slow down the corrosion of reinforcement in concrete.
★ usage method:
No trace of rust Type 1 Metal treatment agent Soaking Brush evenly can , if used Ultrasonic and Heating treatment process can improve the speed and effect. Heat to At 35-40 ℃, the treatment process can be completed in 8-15 minutes. one kg . No trace of rust Type 1 Brushable 20-25 Square meters. No trace of rust Type 1 The treated workpiece does not need to be washed , can be compared with Meiguda continued the operation. No trace of rust Type I is applicable to carbon steel, cast iron, etc Derusting Process, no trace of rust Type II is applicable to aluminum, copper and other non-ferrous metals Derusting technology ， No rust prevention treatment is required after rust removal ； No trace of rust six type 、 No trace of rust nine Type V is applicable to carbon steel, cast iron, etc Rust removal process, rust prevention treatment is required after rust removal 。
★ Relevant persons suggest that:
1. Rust Traceless Type 1 Metal rust remover is a chemical product. Do not take it orally. Keep out of the reach of children.
2. Please wear rubber gloves when you have a wound on your hand or use it for a long time.
3. Rust Traceless Type 1 Depending on different working conditions, it can be diluted several times for use. After small test, it can be used in large quantities.
4. If the rust layer is thick, Most of the rust layer shall be removed by hammering and polishing wheel before use No trace of rust Type 1 Can reduce costs
Increase rate.
five ． No trace of rust Type 1, Type 2 Short term anti rust function, generally available 10-30 days 。 In case of long-term rust prevention, it shall be used together with our rust shield rust inhibitor series products.
7. Store in a cool and dry place, and use rustless type 1 every time After that, the package shall be sealed to avoid failure.
8. Please consult the technical personnel of Beijing Zhubao Company for any unclear points before using them in large quantities.
