Here we will compare the performance of Shanghai Yucheng Chemical RP1145 according to the above reference formula. The above formula is a transparent and uniform liquid.

 

1. Anti-rust performance test

Test method: Dilute the above reference formula scheme 1, scheme 2 and scheme 3 into 5% diluent (Shanghai residents' tap water) and name it as diluent 1, diluent 2 and diluent 3. add 5g cast iron powder into 100ml diluent, soak for 1 minute, take it out and place it on filter paper for 24 hours to observe the rust prevention performance.

Conclusion: RP1145 is consistent with the anti-rust performance of competing products, and the anti-rust performance of traditional dimer acid is the worst.

 

 

  1. Hard water stability test

Test method: Scheme 1, scheme 2 and scheme 3 are respectively diluted with 800PPM hard water containing calcium and magnesium ions according to the proportion of 5%, and named as diluent 1, diluent 2 and diluent 3, and allowed to stand for 24 hours to observe whether there is precipitation and stratification.

Conclusion: RP1145 has good resistance to hard water stability.

 

  1. Corrosion inhibition performance test

Test scheme: Dilute scheme 1, scheme 2 and scheme 3 respectively according to the proportion of 5% diluent (Shanghai residents' domestic water).

Test method: Half of the ADC12 aluminum is immersed in the diluent, the other half is in contact with the air, and the oven is baked at 50°C for 8 hours to observe whether the metal is discolored and black.
