KD-L4112 boiler online descaling agent

The circulating water system in the boiler requires neither corrosion to metal equipment nor scaling, clogging, algae propagation, etc., so as not to hinder the normal operation of the low-pressure boiler, so the boiler water needs to be treated regularly. KD-L4112 boiler online descaling agent (non-stop cleaning agent) is used to clean steam boilers, hot water boilers, steam locomotive boilers, flash evaporators, smelting furnaces, electric steam generators and other equipment.
This product is more effective than pickling and descaling: it has a good cleaning effect on various types of insoluble scales that cannot be descaled by pickling. Even stubborn salt water scales can be removed well.
This product is safer than pickling and descaling: it is cleaned under weak alkaline (pH 10-12) conditions, no corrosion damage to the metal, and long-term use has no adverse effects on the mechanical properties and service life of the equipment.
This product is more economical than pickling and descaling: the cleaning is completed during the normal operation of the equipment, and the cost is lower than the regular pickling cost, without affecting production, and no loss of production shutdown.
This product is simpler than pickling and descaling: just add it in proportion, and anyone can operate it.
This product is harmless and pollution-free: it does not enter steam during normal operation of the boiler and does not affect the steam quality. It can be used for the operation and cleaning of steam boilers in the food and sanitation industries. The cleaning waste liquid does not pollute the environment.
Instructions:
steamer:
①Add 50 grams of KD-L4112 boiler online descaling agent per ton of make-up water (including condensate return water), add it to the water supply tank and mix well, and inject the boiler into normal operation when making up water. If there is no water supply tank, a temporary valve and a dosing tank can be installed on the inlet pipe of the water replenishment pump, and the negative pressure at the inlet when the pump is turned on to replenish the water can suck the scale cleaning agent into the water replenishment pump and inject it into the boiler.
②Keep the pH value of the pot water at 10-12. If the pH value is lower than 10, use mixed sodium hydroxide (1 part of sodium hydroxide and 2 parts of sodium carbonate) to adjust to above 10.
③The steam boiler discharges sewage once per shift, and the discharge rate is 8-10% (the boiler with large evaporation capacity and small water capacity increases the number of sewage discharges).
④When the scale thickness is less than 3mm, when the boiler is running at full load for 24 hours, the descaling cycle is generally 30 to 40 days. When the scale is thicker or the load is low, the descaling cycle needs to be prolonged. Silicate scale appropriately prolongs the descaling cycle.
⑤When draining, all drain valves should be drained, and no blind spots should be left to prevent deposits of dirt particles. The scale cleaning agent must be used continuously during the descaling period, and should not be interrupted, otherwise the descaling cycle will be prolonged and the dosage will be increased. Drain the dirt on time when descaling, so as not to block the pipeline due to the deposition of dissolved scale particles. Insufficient sewage will reduce the cleaning efficiency. When the amount of medicine is insufficient, the cleaning efficiency will be reduced (the scale is not clean), and the scale cleaning agent should continue to be used for cleaning.
