Detergent & Soap-12

Directions for Use and Dose Rates

Soak Method:-
It may be used concentrated or diluted with water, depending on the degree of contamination, the surface area to be treated, the desired degree of cleaning and the available downtime.Actually, the user is the best one capable to regulate the quantity and concentration to be used for the situation at hand.In any case, when the accumulation is not heavy, a 50% solution with water must be used. Otherwise,RXSOL-22-2201. can be used undiluted especially when deposition is heavy and hard spots persist.

Cleaning Procedure

Conventional cleaning methods such as a brush,hard sponge, thick and hard broom and /or a mop can be used on heavy duty and hard stain deposits.Note that for heavy accumulations the cleaning procedure might be necessary to be repeated until the results are satisfactory. Furthermore, is important to keep in mind that 1 litre of RXSOL-22-2201 is sufficient to cover a surface area of 8–10 square meters.

NOTE ::: -- Let this product soak into the surface for 30-45 minutes. Then using a high-powered spray washer blast the surfaces until the stains and discoloration is gone.

Note:-
• Cleaning time will vary depending on the extract nature and thickness of deposit to be removal.
• Stubborn deposits should be scrubbed to assist the cleaning operation.

Your local Rx CLEANSERS representative will work with you to design the optimum concentration & procedure for your system.
RXSOL-22-2201 should be mixed with fresh water to form a solution of 10-30%, depending on the extent of scaling. After using RXSOL-22-2201 it is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of Alkalinity Control in fresh water. This solution should be circulated for 2-4 hours or until an acceptable pH value is obtained. This will neutralize any remaining acidity & passivate steel surfaces.

Dilute concentrated cleaner with warm water using 1 part Heavy Duty Alkaline Cleaner and 1 part water. 

Apply mixed solution with a mop, sponge or sprayer. Avoid applying cleaner on unintended surfaces.

Lightly rub with a scrub brush or floor machine as needed. Allow cleaner for emulsification 1 to15 minutes for best results— do not allow to dry on the surface.

Remove solution using a sponge, wet/dry vacuum or damp mop.

Rinse the area well with clean water. 

TYPICAL METHOD::: Dilute to proper ratio for the desired task, apply to surface and allow adequate contact time, wipe or rinse away. 
Can be Use dilution of 1:100: 11.0 - 11.5 (1:100). 

GENERALLY ::: In an aqueous solution, at a concentration from 10 ml to 200 ml per liter of water, depending on the degree of contamination. 

For Boiler Cleaning :::

5 Ltr is sufficient for 1000 LTRS OF WATER.

The boiler should be warmed through by a slow fire, keeping the manhole closed, immediately after adding the chemical and pressure allowed to rise slowly. It should be raised sufficiently to
give a strong blow of steam at the air cocks. It should be allowed to cool and later blown down for about 15 seconds on each blow-down valve and refilled to about 5 cm level in the gauge glass. On the following day, carry out the same process except that the pressure is raised to approx 25 percent of the normal working pressure. On the third day, carry out the same process and then drain the boiler as detailed below –
When the pressure falls to 0.04 MN/m2 (0.4 kgf/cm2), the unit is blown down completely until it is empty, refilled to flood the drum and superheater and blown down again. It should then be carefully inspected. If any trace of oil or grease is observed, the process of boiling-out should be repeated. If the boiler is found free from grease or oil or sediment, it should be closed and filled with feed water as specified by the manufacturer.

Take Full container / Pouch of RXSOL CPLP Concrete Pipeline Lubricant Powder   in 50 - 75 Ltr of water, Mix Properly to Get Homogenious Light viscous solution. Then use the RXSOL CPLP water mixed slurry solution in PUMP PIPELINE  prior to concreting. its aqueous solution homogeneity is good, leave standstill 9 hours not stratified.The pump line inwall is smeared evenly when pumping, and is effective.

Dirt attached on air-side fins of air coolers are a mix of carbonaceous particles such as soot and oil mist of unburned fuel components. 
Carbonaceous particles can be removed by Alkaline Cleaners Part No. RXSOL-16-1040-025 ( www.rxmarine.com/alkaline-air-cooler-cleaner ) and oil mist can be removed by oil based cleaners. However, it is very difficult to remove the mix of these substances. If you use an alkaline cleaner, oil will repel the water based alkaline cleaner; if you use oil based cleaner, carbonaceous particles will get in the way and stop oil from being removed.

This cleaners designed to remove both carbonaceous and oil simultaneously. An effective cleaning method is to immerse one side to remove the loose stains first, and then immerse the other side. This method can efficiently remove dirt and prevent swollen dirt peeled from fins from blocking the spaces between fins.

Dirt in tubes of seawater side

White scales attached on the seawater side of air coolers of many vessels. We found that in most cases, the main component of the scales is calcium carbonate and there is also a small amount of calcium sulfate. Therefore in most cases, if you dissolve the calcium carbonate the scales will be removed.

However, if the amount of scales is large enough to block the tube, the cylindrical scale will usually have calcium carbonate on the outside (the side that is in contact with tube) and calcium sulfate in the center (part that seawater passes through). Calcium sulfate is easier to be formed when the temperature goes higher.

When the amount of scales increases, the contact area of scale and cleaner is very small and a longer time of dissolution is required. Calcium sulfate cannot be dissolved by an acid cleaner.
