The Key to a Good Coating Job Mechanical adhesion of a paint is associated with surface roughness or “anchor pattern”. Anchor pattern is the surface profile formed by peaks and valleys on the substrate. By increasing the number of hills & valleys,Guest Posting the surface area of the substrate increases which in turn gives an improved adhesion. Blast-cleaning to a surface roughness of 50 microns may increase the surface area up to 45-50 % compared with a smooth plate. Surface preparation methods include both mechanical cleaning and blast-cleaning. For mechanical cleaning we have two main methods, hand tool cleaning and power tool cleaning. For blast-cleaning we have several methods which will be described later in this chapter. For large surfaces, mechanical cleaning is more expensive than blast-cleaning. It is therefore used mainly for local repairs, removal of rust spots and treatment of damaged or burnt areas and welding seams. Results can be very variable and the process will generally be a relatively slow one in order to be effective. On heavily rusted surfaces, heavy deposits have to be removed before more thorough surface preparation methods are employed. After hand or mechanical tool cleaning and prior to painting, re-clean the surface if it does not conform to the specification. Prior to painting, remove dirt, dust, or similar contaminants from the surface. Acceptable methods include brushing, blow off with clean dry air, or vacuum-cleaning. Hand Tool Cleaning Hand tool cleaning is one of the oldest methods of surface preparation of steel surfaces. A hand tool cleaned surface is free from loose rust, loose paint and loose millscale. It is not intended that adherent millscale, rust and paint should be removed by this process. Millscale, rust and paint are considered adherent if they cannot be removed by lifting with a dull putty knife. Scraping, wire brushing and chipping are used as methods for removing rust & old paint. Before hand-tool cleaning, make sure that dirt, grease and oil have been removed from the surface. A hand tool cleaned surface is desirable for applications where a low cost cleaning method is required and a short life paint system can be tolerated. A coating with good penetrating properties (epoxy mastic) gives the best result. When scraping or wire brushing manually, much effort is needed to remove as much rust as possible. Since only a few square feet per hour can be satisfactorily cleaned, this method should be limited to small areas and when a high level of surface cleanliness is not required. Power Tool Cleaning There are two main types of power tools;
Rotary cleaning tools
Impact tools
In general the rotary cleaning tools are the most effective ones in removing paint and rust, while the impact tools are more effective in removing scale and pack rust. Common rotary cleaning tools are wire brushes, coated abrasive and non-woven abrasive. Wire brushes can remove paint, loose mill scale, rust & weld slag, but tend to smoothen or burnish a surface and give bad adhesion for a coating. Do not use high speed wire brushing as a surface preparation method before painting. Coated abrasive (disc grinding) can remove paint, loose mill scale and rust, but tends to clog up when paint is removed and may remove some of the substrate material. Non-woven abrasive does not clog up as much when removing paint and it can take a surface to bare metal and yet remove only negligible bare metal. Common impact tools are :
Pneumatically driven hammers or rotary hammers
Needle guns
Chisels
These impact tools are very noisy, slow and subject to damaging the steel substrate, but are effective for removals of rough scale, including heavy laminated scale. The use of needle guns should be limited to welds, corners, uneven edges etc. as the impact of the needles can cause an unacceptable profile on flat surfaces. “Non-spark” tools may be necessary in areas subject to fire or explosion hazards. ISO 8501-1 has two grades of cleanliness after hand and power tool cleaning on rust grades B, C and D St 2 & St 3. 1 → Needle Gun , 2 → Pneumatic Chipping Hammer Abrasive Blast Cleaning – Sandblasting Blast-cleaning is the common term for all methods using abrasives that are propelled toward the surface to be cleaned at very high speed. Different kinds of abrasives are propelled either by high velocity compressed air, centrifugal force or by a high-velocity stream of water to remove rust, mill scale, existing coatings and other contaminants from the substrate. The different methods of blast-cleaning are :
Centrifugal abrasive blast-cleaning
Compressed-air abrasive blast-cleaning
Vacuum or suction-head abrasive blast-cleaning
Moisture-injection abrasive blast-cleaning
Wet abrasive blast-cleaning
High pressure and ultra high pressure water-jetting
Of the above, the most common methods today are dry abrasive blast cleaning, centrifugal abrasive blast cleaning and high pressure water jetting.
Centrifugal Blast Cleaning
Centrifugal abrasive blast-cleaning is carried out in fixed installation or mobile units in which the abrasive is fed to rotating wheels or impellers positioned to throw the abrasive evenly and at high velocity on to the surface to be cleaned. The abrasives used are usually a mixture of steel grit & shot, and the abrasives are re-circulated.
This method is suitable for continuous treatment of plates for removal of the mill scale & surface corrosion and for profiling the steel plate. Normally, in connection with the centrifugal blasting machine there is an application unit which automatically applies a shopprimer or prefabrication primer on the steel. Major yards have their own plant, while smaller yards buy their steel ready primed from specialist companies or steel manufacturers.
The blast-cleaning standard should be Sa 2 ½ (according to ISO 8501-1) before the shopprimer is applied. The shop-primer’s paint inspector should check the plant and ensure that this degree of cleanliness is maintained before the shop-primer is applied. However nowadays, the major part of construction steel is delivered centrifugally blast cleaned & shopprimed, allowing little opportunity to check the quality of the shot blasting.
The shop primer, which is intended to provide temporary protection, is applied to a specified film thickness by an automated process. The thickness is usually 15 – 20 microns for iron oxide shopprimer and 10 – 15 microns for zinc shopprimer. It is very important to keep inside the specification, because excessive shopprimer thickness will reduce the cutting and welding speed and thereby prolong the production time at the yard.

Pickling
Acid pickling is an old established shop method of removing millscale from steel. There are several detailed processes still in use, often employing a duplex system of aggressive and passivating acids. One disadvantage of pickling is that it leaves the steel clean but witho

In this article, we will describe about Dry Vs Steam Carpet Cleaning Methods. Our Carpet Cleaning methods are mostly used by professionals and it is very effective.
Have you ever thought that even after proper cleaning,Guest Posting your house, office, hotel rooms, etc. seems to be full of dirt? Moreover, do you see frequent episodes of allergies and infectious diseases affecting you and the people around you? Do you sense a damp and unclean environment around you? Then, there is a high chance that you are a victim of unclean and unhealthy carpet at your place.
What Are the Options We Have Then to Keep the Carpet Clean and dirt-free?
No matter how much you say that “My carpet is clean” there is still a high probability that germs and stains are residing in the carpet.
Let us have a quick look at how an unclean carpet affects you.
An unclean carpet means inviting germs, allergies, infections, fungal growth, and breathing issues. Kids and your pets are the most affected. The allergies can also be contagious, and so it means that more people can get infected.
Unclean carpet also means bad odour and can lead to nausea and headaches.
Spots and stains may be easily removed superficially but can be difficult to deal with when they are residing deep inside the carpet. “Stains” does not only mean marks and spots. The residue of a liquid spill or food spill, etc. are part of stains and are again a cause of an unhealthy environment.
Another thing to realize is that the carpet and its installation is not a pocket-friendly affair. So, where dust is a problem, liquid spills, food spills, soiled legs, bloodstains in hospitals, etc. are some other big challenges to be considered.
What are the Carpet Cleaning methods?
Over the years, many cleaning methods have evolved and the same is the case with the carpet cleaning area. We have advanced cleaning agents and tools in the market today that make the cleaning task easy and highly reliable.
There are two options available for carpet cleaning, wet and dry carpet cleaning. The IICRC has researched over the years and laid down clear standards for these methods.
Wet Carpet Cleaning – This involves steam, foam, and shampoo based cleaning methods. A mixture of chemicals, cleaning shampoo (if required), and steam is sprayed on the carpet as per the cleaning method used. The spray is allowed to settle down so that it acts on the stains and residue. Vacuum extraction is then used to clean the carpet.
Ever seen a person at the airport sitting on a vehicle that has rotators and constantly moving over the carpet? Wet carpet cleaning technique is used in that case.
Dry Carpet Cleaning – Most people think that the dry carpet cleaning method means simple vacuum cleaning. Though it is true to a certain extent, it also uses dry chemicals and just enough water to create moisture. The mixture is allowed to settle down and the carpet is then vacuum cleaned. This method is less intensive but is cheaper than the wet cleaning method.
Note: No matter what method you choose, a pre-dry cleaning of the carpet is always beneficial.
Steam-Based Carpet Cleaning method
Steam carpet cleaning the most popular method used for carpet cleaning. Most people do not go for the dry carpet cleaning method because it is less effective and the use of dry chemicals can damage their carpet.
Steam-based carpet cleaning uses a mixture of certain cleaning chemicals and hot water. Today, there are many machines available for easy and effective carpet steam cleaning. Some machines directly use hot water and some include a heating mechanism. The machine allows the mixture to spread evenly and act on any residue and stains. It also soaks up moisture and excess water.
Dry vs Steam Carpet Cleaning
There are pros and cons of both the methods.
Dry carpet cleaning is a bit cheaper when compared with steam carpet cleaning.
Steam carpet cleaning is most widely used today than dry carpet cleaning because the chemical solution deeply penetrates the carpet due to more water content. But, it also depends on the chemicals being used. The dry chemicals used in the dry carpet cleaning may be better suited for your carpet but may also be harmful.
Steam carpet cleaning being a subset of wet carpet cleaning requires more time for the carpet to dry. It can take up to 24 hours or more if there is no proper air circulation. Dry carpet cleaning almost instantly allows the carpet to dry up and is ready to be used.
Go For the Professional Help to Choose the Right Cleaning Method
You must always consider professional help for your carpet cleaning. The professionals have the required expertise and experience to decide what cleaning method is best suited for your carpet. Let experts analyse the carpet fabric, usage patterns, the chemicals to be used and the level of cleaning required to keep you and people around you free from any worries.
