Product Name: UNITEDCHEM-RUST
It is suitable for all metals including aluminum and zinc silicate coated tanks. It efficiently cleans all kinds of rust and rust stains that are formed in warehouse and cargo tanks. It is also used in the cleaning of magnesite and bark of white stains (after washing with caustic-based load or caustic containing chemicals) in tank walls.
The dilution ratios of UNITEDCHEM-RUST vary depending on the type of metal, scab, lime and rust density.
1 – CIRCULATION METHOD
Prepare the cleaning solution in an empty slop tank or in a tank immediately adjacent to the pump chamber. The cleaning solution is prepared with UNITEDCHEM-RUST at 5%. Afterwards, the solution is circulated in the tank with the aid of the heater and tank washing system. The chemical solution returns to the slop tank from the tank with the leaching cycle tube.
It is not usually possible to re-circulate the solution through the tank washing heater (to keep the temperature of the solution constant) without making a temporary connection between the chemical solution preparation tank and the tank washing pump. The capacities of slop tanks, pipelines and pumps must be calculated carefully so that a sufficient volumetric quantity can be maintained in the continuous circulation of the chemical solution. Depending on the condition and size of the tanks to be cleaned, besides the amount of chemical solution, only a single chemical solution will generally clean the stains on only 2 tanks. After cleaning, the tanks are rinsed with fresh water and the exact result is obtained. Circulation time is 2-3 hours.
2 – SPOT (POINT) CLEANING METHOD (WITH TANK WASHING MACHINERY)
1/1 – 1/2 UNITEDCHEM-RUST + water solution is prepared for cleaning rust and rust stains. It is also suitable for use with cold water. It is expected to react on the surface as much as possible, and brushing is recommended on dense rusty surfaces for 15-20 minutes. It is then cleaned with the help of abundant water. If the surface to be cleaned consists of sensitive metals, 1/3 – 1/5 of the solution should be prepared. Wait for up to 5 minutes after application and immediately rinse. 5% solution should be prepared for cleaning of white stains from tank surfaces, rinse with fresh water for 5-10 minutes.
