Mianyang Tianming Phosphorus Chemical Industry Co., Ltd. is professional manufacturer of Phosphate Chemical and unique producer of Minghuang Gui Lin Jing in China. Minghuang Gui Lin Jing is a food-grade polyphosphate; Which is in high purity and produced through high temperature above 1000 ° C, thus made it suitable for tap water treatment. Minghuang Gui Lin Jing is a glassy ball with diameter of about 20mm, which is used to prevent scaling and corrosion of water pipes and equipment. It is colorless, odorless, non-toxic, friend to environment and harmless to human, with sparingly dissolved characteristics in water.
The comprehensive features of Minghuang Gui Lin Jing may described as in equivalent to Siliphos, Microphos, Klorofos, Kristalfos, power-phos and Calsphos, those, in generally, accepted for treatment of city main water.
1. The anti-corrosion & scaling mechanism of Minghuang Gui Lin Jing
Anti-corrosion:
Trace active ingredients in Minghuang Gui Lin Jing isolate metal reacting with dissolved oxygen, prevent ferrous hydroxide turning to ferric hydroxide, namely passivating action. An amorphous self recovering protecting film will be generated on inner pipe wall, which is mono- molecularity, preventing dissolved oxygen corroding metal, thereby suppressing the entire corrosion.
Anti-scaling
The main components effectively restrain and interfere with calcium carbonate crystal normal growth, and control nucleation rate, so that prevent the formation of scale; Meanwhile, the formed calcium, magnesium, and iron scale will interact with Minghuang Gui Lin Jing, pooled by Brownian motion or water flow effect.
Sanitation and Safety of food-grade Minghuang Gui Lin Jing
Minghuang Gui Lin Jing is differ from other water treatment chemical agents, it is a safe and sanitation-grade product, which can be used in drinking water pipelines and equipment. The dosing rate is 1-3ppm, which can play the role of preventing scaling and corrosion.

Applications
1). Anti-corrosion, anti-scaling in drinking water pipelines, prevention rust (red) water, yellow water and clogging pipes
2). Various heat exchangers, hot water boilers anti-scaling, ensuring high efficiency heat transfer, energy saving, and lower consumption.
3). Various water equipment, such as coffee machines, ice machines, tea furnaces, gas heat exchangers, electric water heaters, solar water heaters, steam-boxes, dishwashers, bath shower and etc.
4). Industrial circulating water treatment
Central air-conditioning refrigerating batteries, circulating cooling water, chilled water, heating
3. Dosing equipment selection.
The size of Minghuang Gui Lin Jing dosing tank depends on users' average water requirement. A dosing tank filled with Minghuang Gui Lin Jing balls will be installed in the pipeline according with your daily water requirement. The Minghuang Gui Lin Jing will bring you an unexpected effect, through using it. "The original scale disappeared, as well as the yellow water, red water. " What you need do is dosing chemical once a 3-6 months, while for household application one year period refill can be expected. When Minghuang Gui Lin Jing inside the container, it's level is below the line which can be seen on the glass window, it means that refill is required. Amount of 1/3 of the initial loading in general required.
