Abstract

The invention relates to a desiccant for adsorbing ammonia and the preparation method, mainly comprising Ca(H2PO4)2, nanometer kaolin, and zeolite powder, and Ca(H2PO4)2, CuSO4, FeSO4, and Blumea oil. The desiccant adopts powder that can be used directly. The desiccant has the advantages of: ability to adsorb ambient water, relieving infection on the environment of the humidity; ability to kill virus, and bacteria in long term for that the solid powder has the ability to be stayed in the environment, and that the action time is long, and ability to absorb ammonia, making the environment be refreshing, dry-touch, and be suitable for animal survive and produce, satisfying the welfare requirements of animals.

Description

technical field [0001] The invention relates to a desiccant, in particular to a desiccant for adsorbing ammonia and a preparation method thereof. Background technique [0002] Since the reform and opening up, my country's animal husbandry industry has achieved tremendous development, and the number of livestock and poultry stocks and slaughter has already ranked first in the world. However, with the continuous development of intensive farming, ammonia and humidity are becoming the two most prominent problems that endanger intensive farming due to the high density of farming. [0003] Generally speaking, when the ammonia concentration reaches 5ppm, it will be felt by the human body; when the ammonia concentration exceeds 20ppm, it will have a negative impact on the survival and production of animals; when the ammonia concentration exceeds 50ppm, it will cause Broiler keratitis, respiratory disease, digestive tract injury, pig throat congestion and other diseases. In practic...
