OIL CLEANING BIO-PRODUCTS LTD.
CONCENTRATED BIOREMEDIATING PARTS WASHING & DEGREASING LIQUID
Bacterial parts washing liquid
HEGSURF.pw is a blend of biodegradable surfactants, non-pathogenic oil-degrading bacteria and nutrients. It is a safe alternative to the use of harsh solvents and caustics in degreasing metal parts. It removes hydrocarbons and other organic chemicals from soiled metallic or other surfaces. In the right conditions the natural bacteria in the product will biodegrade the oil and grease in the circulating residue into harmless by-products and thus extend the effective life of Hegsurf.pw as a parts-washing liquid.
BENEFITS
- Quick recombination of oil makes it possible to skim oil residues from the surface if required
- Use in ultrasonic parts washers and ordinary dip tanks
- Can biodegrade oil residues, rather than merely moves contamination from one point to another
- Rust inhibitor protects degreased metal work
- Will not damage rubber or plastic parts; safe on paintwork
- Safe to use; non-flammable; no cumbersome precautions needed;
- Cuts fumes/VOCs; greater working flexibility and improved health at work cut costs
DIRECTIONS FOR USE
NOTE: The powdered bacterial bran contained in the inner cap is sufficient for the entire volume of concentrate in the container. When using part of the liquid only, use a proportionate amount of the bacterial bran, i.e. when using 1/4 of the concentrate add only 1/4 of the bran, and then add clean water, preferably lukewarm. Let stand for 30 minutes before use. If the solution thickens after some time without use, simply add water. Dilutions below are shown in ratios of water:Hegsurf.pw.
NOTE: The effectiveness of Hegsurf.pw will be reduced by contact with brake fluid or carburettor cleaner. If the solution thickens after some time without use, add more water.
CONVENTIONAL CIRCULATING PARTS WASHERS
HEGSURF.pw should be diluted with water 5:1, or up to 10:1 if the greasing or caking is not severe. After adding the bacterial bran as described above, leave the mixture to stand for up to one hour if possible. The mixed solution can then be used exactly as in a conventional parts washing fluid, except that it does not pose the same problems of disposal. Ideally the working temperature should be about 100°F/40°C., but ordinary room temperatures will suffice. Hegsurf.pw itself may be used at higher temperatures, but the the bacteria will not function above 45°C.
ULTRASONIC PARTS WASHERS
HEGSURF.pw works well in ultrasonic parts washers. Hegsurf.pw be mixed as described above but in a weaker dilution of 20:1 up to 50:1. The higher dilution ratios are for greasing or caking which is not severe.
SOAK TANK OR SWABBING
Mix as for conventional parts washing and dilute according to the extent of grease to be removed. For light rust-inhibiting oils a solution of up to 20:1 should be effective.
DISPOSAL OF USED HEGSOLV
When Hegsurf.pw is exhausted, a slight odour of ammonia becomes apparent and the solution in the parts washer should be replaced. However, it may still be used for cleaning oil-stained concrete floors. Proceed as follows:
1) Ensure that non-biodegraded oil in the solution is either skimmed from the surface or removed through physical absorption by a Hegsorb pillow;
2) Pour the oil-free solution on the floor to be cleaned, spread with a mop (a stiff-bristled broom may needed to scrub areas of heavy contamination) and leave for at least 15 minutes;
3) rinse the floor with plenty of water, using a hose or mop, so that the residue flows to the site drainage system and separator.
Used Hegsurf.pw may be added to used Hegfloor, Hegrem or Hegsorb. The Hegsurf.pw will assist their composting while biodegrading itself.
