Boiler maintenance and maintenance!

● Importance of using maintenance agent After the boiler is deactivated, the outside air will enter the furnace system in a large amount, and the water film attached to the metal surface of the furnace body will form an oxygen solution with the air to reach a saturated state, causing dissolved oxygen corrosion, and the corrosion rate is Ten times the operation, plus residual scale, the corrosion is more intense. It is proved that most of the boilers that cause serious corrosion are caused during the shutdown, so maintenance measures must be taken during the decommissioning.
●Product performance This product is white granule or white powder crystal, non-toxic, odorless, and the function is physical adsorption. It can absorb 40-50% of its own weight of water, and can be oxidized under saturated conditions, and release carbon monoxide to capture oxygen to protect the boiler from oxygen corrosion. At the same time, it is suitable for polar substances such as (H2O) gas Ba3Pa5. It has strong adsorption force and produces chemical adsorption to O2H2CO and CO2N2.
●Using method and dosage will be placed in the steam drum, superheater pipe, each junction box and equipment evenly in the air bag (15-20 kg of boiler maintenance agent per M3 space). The boiler must be placed after drying. Immediately close the steam and water valves to prevent outside air from entering.


HLX-105B boiler shutdown maintenance agent is a new product developed by our company's technical personnel under the guidance of the national anti-corrosion experts of China Chemical Anti-corrosion Association. The product has been used in tens of thousands of deactivated boilers and has achieved good results.
●Application range Various equipments that use water as heat exchange medium or cooling medium are applicable. Performance Appearance: white powder or viscous liquid of colorless or micro-colored. The product is environmentally friendly green product, non-toxic, odorless, composed of silicate, polyphosphate and a variety of inorganic synergists. Water is added to form an alkaline environment, after reaction, polysilicate anion And a negatively charged colloidal ion is a component that has a strong affinity for the metal surface. It forms a dense, impermeable molecular film (less than one micron) on the rusted and clean metal surface. The characteristic can prevent the contact between the metal surface and the anion and dissolved oxygen in the water, thereby preventing the occurrence of metal oxidative corrosion and galvanic corrosion, preventing the occurrence of "red rust" phenomenon inside the boiler equipment system, thereby achieving protection of the metal equipment and extending The service life of the equipment.
●Usage method Fill the water with a specified proportion to fill the boiler or other equipment.
●Dosage The protection period is 4 months, adding 5000 grams of this product per ton of water. If the protection period is 6 months, 4 months later, add 2500 grams of this product per ton of water.
Technical indicators: Hanging sheets after soaking for 6 months in oxygenated water, the corrosion is as follows:
Material Brass Cast iron Copper Carbon steel Corrosion rate mm/y 0.0029 0.065 0 0.042
The surface state is as bright as the beginning, the light is as bright as the beginning, the light is as bright as ever.
