Main Use and Functions:
Jinli Minerals is the first in North China to set up an advanced digital thermostat to cool, select, winnow and grade its products .Jinli has produced and developed many products ,which have such advantages as lighter, easy to reduce high-temperature recession heat and cold and corrosion resistant, better ventilation and water preservation , poisonousless and odorless, low hardness, burning-avoidance.
It has already been used in many fields like construction materials ,heat-resistant materials ,sheet materials costing painting painting rubber, agriculture, forestry, nursery gardening ,forage, cultivation ,pharmacy, fricition and sealing, metallurgy, etc.
