High Pressure Blasting Cleaning

Blasting is a method of cleaning which involves forceful pushing water against a surface, causing the particles to be blasted away from the surface through a high-pressure stream. The most common way of blasting is by using pressurized water, as it is highly effective and causes little damage to any objects that are cleaned. There are many ways in which High Pressure Water Blasting can be carried out, and different techniques are used depending on what type of debris or what type of surface needs cleaning. The main ways in which High Pressure Water Blasting is carried out are outlined below.

High Pressure Water Blasting is a highly effective cleaning method that can remove dirt and stains from all types of surfaces. High Pressure Water Blasting and Pressurization are both important factors in successful High Pressure Water Blasting Machine operation. In most cases, hard and soft surfaces respond well to high pressures, which means that softer items are better removed with lower flows. In residential areas, where high pressure water blasting is frequently carried out to clean surfaces, the most commonly found use for this method is to remove dirt from driveways and gutters, where surface grit and dirt collects in the course of regular use.

Commercial areas, though, often require much stronger and more abrasive cleaning services for various reasons. These include the need for more efficient use of water in the course of cleaning services, the requirement for surfaces to be made smoother and easier to clean with abrasive cleaners and the requirement of removing impurities from water. Aggressive water blasting services in commercial areas are often needed for such purposes as removing stubborn stains from concrete and stone, which cannot be cleaned with normal abrasive cleaners. In addition, most companies that provide commercial services also carry out water jetting and power washing, which involves the use of high pressure water jets to clean surfaces such as glass and granite. These methods require very strong jet pressures and water jets, which may damage the surfaces they clean.

To make use of these methods effectively, it is important to control the PSI (pounds per square inch) and the GPM (gallons per minute) of the water used. The PSI refers to the pressure of the water blasting nozzle, while the GPM refers to the flow rate through the nozzle. When a high PSI and a low GPM is combined, the result is a stronger water jet with a correspondingly stronger stream and the effect is often that the scrubbing action on the surfaces being cleaned is much more extensive. In this case, though, higher PSI and higher flow rates are often required to get the desired results.

This is another important consideration when selecting a pressure cleaning method. For residential areas, low PSI and low GPM may be appropriate, especially when the surfaces to be cleaned are likely to be less sensitive than those in industrial or commercial settings. However, when working with concrete or steel surfaces, especially where cracks may occur, high PSI and higher GPM is usually required. When this is the case, the effect of the water jet is usually not sufficient to achieve the results desired, especially when the surfaces to be cleaned are not flat. This problem is addressed by using special hydro blasting machines.

In order to achieve the best results from a pressure water blasting system, the correct PSI and GPM are needed, as well as the right nozzle type. When selecting the nozzle, it is important to select one that does not require any external air, such as a carbon dioxide laser, to operate properly. High efficiency air-operated nozzles provide the best value for money and are capable of delivering very powerful jet streams without the requirement for excess air. If an air driven nozzle is used, then the flow rate must be controlled in order to prevent overpressure. A high flow rate nozzle produces a more even spray with minimal damage to the surface and is a better choice for low-porosity concrete or slate, but will need a larger nozzle to cover large areas.

In addition to jet pressures, water blasting systems also use different chemicals and other cleaning solutions. The most common chemicals used are sodium hypochlorite and calcium hypochlorite. Other chemicals commonly used include alkydsulfide and perchloric acid. These are sometimes combined with either calcium or magnesium, which are added during processing to achieve specific surface preparation requirements. These chemicals can also be used in conjunction with steam or pressurization to increase cleaning efficiency. Steam cleaning is the most commonly used method of pressure water blasting, but dry chemical methods are available and some surfaces can be treated by direct injection of a chemical solution.

High-pressure water pressure and the chemicals used depend upon a number of factors, such as the surface to be cleaned, its hardness, and whether or not the area is pre-cleaned. Some chemicals require additional stages of processing before they can be safely used in residential and commercial settings. For example, most abrasive cleaners and polishes are mixed with resins in order to form a fine mist that cleans bare metal, but the beads or particles may not dissolve properly and flow onto other surfaces. When this occurs, the cleaning agent quickly wears away at the surface, leaving an abrasive residue behind that can scratch paint and damage sensitive equipment. Commercial cleaners that contain resins are designed to prevent the beads from flowing onto other surfaces, and many contain Na 184, which is a saltine solution that prevents the beads from sticking to soft metals.
