QW-123 Scale and Rust Remover
Introduction:
The scale and rust remover contains compound acid, resists, decaling accelerants and other components and can quickly and thoroughly dissociate the accumulation of accumulation layer scale, rust scars and other mineral substances to rinse both precipitates and silt in water.
Feature: (colorless; specific gravity: 1.05±0.05; PH value: 1; and odor: fragrance)
The scale and rust remover can effectively restrain the corrosion to copper, iron and other metals, so that the hazards of stress are controlled to the lowest limit, and no effect on a vast majority of coating is caused; and it is free from the hazards like those of concentrated hydrochloric acid and concentrated sulfuric acid, is safe in use and wide in application scope and has an obvious effect on carbonate, sulfate, rust scars, rust stains and slime.

The scale and rust remover is applicable to removing the scale, the algae and the rust dirt of precision heat exchangers, air coolers, air compressors and air-conditioning equipment, the pipe scale of metal in-mold water pipes and working oil cooling pipes in the plastic forming work, the concrete thin layer attached onto the surfaces of construction machinery and the like, the water rust on building ceramics and mosaic, the green algae and the water rust attached onto the surfaces of concrete water tanks and swimming pools, and the rust, the plaque and the dirt of copper, copper alloy and the like on washing power distribution equipment.
Using method:
□  Heat exchanger device and air cooling device: diluting the scale and dust remover for 5-10 times, injecting into the circulating system and soaking for 1 hours; and then continuously circulating for about 12 hours and keeping the PH value of circulating liquid to be 1. Removing cleaning liquid after the completion of circulation, circulating with clear water, then neutralizing with QW-124 neutralizing agents or self-used lyes till the PH value of liquid at the inlet is consistent with that of liquid at the outlet and ensuring that the ratio of neutralization with soda ash is 1‰-3‰.
□  Air-conditioning fins: adding water into the scale and dust remover for 5-10 times (according to the fouling degree), repeatedly spraying the diluent and fully washing with water after the completion of reaction.
□  Cleaning of rust scar and plaque on metal parts: firstly coating QW-123 stock solution and then rubbing with a steel wire brush after several minutes. If possible, directly soaking the workpiece into the stock solution. After the completion of cleaning, cleaning with water, and finally, drying and coating with the anti-rust oil.
Precautions:
□  Do not be in contact with skin for a long time as the scale and rust remover is acidic.
□  Firstly clean a small area of ceramics, marble and other products and then trustingly use after the safety is proved.
□  Do not rinse for a long time as the scale and rust remover has an effect on stainless steel.
Package: 25 kilograms/barrel.
