We can't live without water in our daily lives, and even more so in modern businesses, where water and various forms of water equipment are essential. For example:
Heat exchange equipment: water as a medium for other equipment or media to provide heat exchange equipment. For example: central air-conditioning condenser and table cooler, centralized heat supply equipment heat exchanger, petrochemical enterprises, water-cooled units of the system, the iron and steel industry, air compressors, nitrogen presses, plastics industry, injection molding machines, automotive industry, the engine's cooling water tank and so on.
The adverse effects of scaling in the water system:
1. Waste of energy:
Scale will make the thermal conductivity of the heat transfer surface deterioration, fuel combustion release of energy due to scale blocking can not be transferred to the water in a timely manner, resulting in a reduction in the efficiency of heat transfer and waste of energy (the thermal conductivity of the scale is only about 1% of the metal material).
2. Affect the normal operation of the equipment:
Experiments show that 1 millimeter of scale will make the heat transfer efficiency reduced by about 10%, equipment scaling, due to the blockage of heat transfer, will make the equipment localized heat serious, while the need to warm up the medium and can not get the heat, so that the efficiency is greatly reduced, and even forced to shut down, high-pressure cut-off and other issues.
3. Reduce production efficiency:
Heat exchanger fouling will directly lead to reduced efficiency, for example: boilers are not fouled before an hour can boil the water, fouled heat transfer efficiency will decline, this time it takes a few hours or even longer.
4. Shorten the service life of the equipment:
Scaling will make the equipment uneven heating or localized overheating phenomenon, will make the equipment pipe wall burst and other problems. For example: low-pressure boiler scale-free operation of the tube wall temperature of 280 ℃, when the thickness of the tube wall fouling up to 2 mm, the local temperature of the tube wall can be as high as 480 ℃, the strength of the steel is reduced by about 3/4, at this time it is very easy to burst and other issues.
The surface structure of the equipment has a great impact on the need for timely descaling, so what are the traditional methods of descaling?
1. Mechanical descaling:
The use of metal tools descaling, such as: hammering, sharp tools scraping shovels and so on. This way is not only more labor-intensive, descaling is not complete, and closed the small heat exchanger pipeline can not be removed, at the same time it will be very easy to scratch the equipment, damage to the equipment and so on.
2. Acid washing descaling:
The use of sulfuric acid, hydrochloric acid or nitric acid and add metal corrosion inhibitors for cleaning, this method is more obvious although the descaling effect, but the corrosion of the equipment is very great, will produce equipment pitting, hydrogen embrittlement and even perforation and other issues; at the same time the acid mist will cause harm to human beings and the pollution of the environment, and there must be a professional operation, reasonable control of the cleaning time and so on.
3. Alkaline cooking descaling:
The use of caustic soda into the high-temperature furnace high-temperature cooking furnace, time-consuming, descaling is not complete, and at the same time very easy to burn the skin.
Prevent the structure of the equipment method?
1. Softening treatment:
Equipment and then add new water, the water quality to do softening treatment, which can reduce the water quality of calcium and magnesium ions, dust and bacteria and algae and other harmful substances in the content, you can prevent equipment scaling to a certain extent.
2. Add corrosion and scale inhibitor treatment:
Appropriate addition of corrosion and scale inhibitors in the circulating water system, corrosion and scale inhibitors will be complexed with calcium and magnesium ions in the water body, the generation of complexes, and regular sewage, timely discharge of complexes from the equipment, to avoid scaling attached to the surface of the equipment, so that you can effectively prevent the internal scaling of the equipment.
3. Regular cleaning and maintenance:
Softened water treatment and add corrosion and scale inhibitor does not guarantee that the equipment is not permanently scaled, only to a certain extent to extend the scaling time of the equipment, to prevent scaling, so the need for regular cleaning and maintenance, save time and effort, do not wait for the scale quality to become more and more thick and then go to cleaning.
Regular cleaning and maintenance of descaling cleaning agent features
Characteristic one: safety.
Descaling series products with test paper test pH ﹤1, with the hand in the bottle mouth gently agitation and put the finger in the bottle shaking a few times, take out, wipe dry and observe, finger without redness and swelling peeling phenomenon.
Add many kinds of high efficient slow-release components and mist suppressant, no irritating odor, harmless to people, equipment and environment, no burning and irritation to human skin.
Characteristic 2: Excellent descaling performance.
The scale piece is placed in the container with descaling agent, you can clearly see that the scale will react violently with the descaling agent, and at the same time, a large number of white bubbles will appear, and the scale piece can be dissolved in a short time.
It means that this product has the characteristics of fast descaling speed, thorough descaling, high ratio of dissolved scale, and it can be used in diluted form, even if it is diluted 10 times, it is still effective and economical.
Characteristic three: excellent rust removal performance.
Will have a layer of light rust on the surface of the copper sheet into the descaling agent, more than ten seconds after the removal, and rinse with water, found that the rust layer and dirt is removed, the copper sheet reveals a metallic luster, while the copper sheet does not have any corrosion.
It shows that this product is not only able to remove
