    Product Description

    DKP is mainly used in agriculture, medicine, food and chemical applications. DKP can be used as fertilizer, analytical reagent, pharmaceutical raw material, buffering agent, chelating agent, yeast food, emulsifying salt, antioxidant synergist in food industry.
    DKP is an indispensable nutrient for plant growth, and it contains a large amount of potassium. By supplementing potassium, the photosynthesis of plants can be rapidly promoted, accelerating the manufacture and conversion of nutrients. Therefore, DKP plays an important role in photosynthesis.


    (1)Corrosion inhibitor for antifreeze, nutrient for antibiotic medium, phosphorus and potassium regulator for fermentation industry, feed additive, etc.
    (2)Used in the food industry as a raw material for the preparation of alkaline water for pasta products, as a fermentation agent, as a flavouring agent, as a bulking agent, as a mild alkaline agent for dairy products and as a yeast feed. Used as a buffering agent, chelating agent.
    (3)Used in the pharmaceutical and fermentation industries as a phosphorus and potassium regulator and as a bacterial culture medium. Raw material for the manufacture of potassium pyrophosphate.
    (4)Used as a liquid fertiliser, corrosion inhibitor for glycol antifreeze. Feed grade used as a nutritional supplement for feed. Promote nutrient absorption as well as photosynthesis and also improve the ability to resist adversity, can promote the fruit has a certain role in strengthening the fruit, but also has the role of promoting plant growth.
    (5)Used as corrosion inhibitor for antifreeze, nutrient for antibiotic culture medium, phosphorus and potassium regulator for fermentation industry, feed additive, etc. Used as water quality treatment agent, microorganisms, bacteria culture agent, etc..
    (6)DKP is used as a buffer in chemical analysis, in phosphate treatment of metals and as a plating additive.
