(I) Metal Corrosion
The acid washing process inevitably causes corrosive damage to heat exchange equipment such as boilers and central air conditioning units. Hydrogen ingress damage, in particular, can disrupt the metal's crystalline structure, leading to severe cases of hydrogen embrittlement and hydrogen-induced cracking, which poses a potential danger to the safe operation of heat exchange equipment.
The environmentally-friendly cleaning agent uses biodegradable bio-acids. According to tests conducted by national authoritative institutions, the metal corrosion rate is only 1/20th of the national standard, and even lower than the corrosion rate of metal in water. It is merely one percent of the metal corrosion rate during traditional acid washing. Remarkably, the undiluted cleaning agent does not cause any harm to the skin.
(II) Cleaning Effect
During acid washing, due to concerns about acid corrosion damaging the equipment, cleaning personnel often avoid prolonged cleaning processes out of fear of equipment damage. This frequently leads to incomplete cleaning, even though some cleaning effects are achieved initially. However, scaling issues reoccur shortly thereafter.
In addition to its non-corrosive advantages, the Foshitek eco-cleaning agent also boasts high descaling efficiency. Each kilogram of the concentrate can remove up to 4 kilograms of scale, and most cleaning tasks can be completed within 2-3 hours, significantly improving cleaning efficiency.
(III) Toxicity and Environmental Impact
Acid washing waste liquid is highly harmful to biological organisms due to the corrosiveness of the acid and the toxicity caused by the decomposition of inhibitors, severely polluting the environment. Acid washing is a highly toxic and harmful cleaning method with significant pollution.
Foshitek's primary components are advanced biodegradable agents that are non-toxic, non-corrosive, and non-flammable. If the scale being cleaned does not contain harmful substances, the waste liquid from the cleaning process can be directly discharged.
(IV) Cleaning Method
Acid washing has a corrosive effect on metals. Operators must undergo strict training, as improper operation can easily cause serious damage to the equipment, potentially leading to scrapping.
Foshitek is very easy to use. After simple training for 2-3 people, an open-loop circulation pump and bucket system can be used to thoroughly clean equipment from the bottom to the top.
