Due to the physical characteristics of ice, the application of ice in chemical industry has been continuously expanded.

In the production of azo reactive dye, dye synthesis process, diazotization, coupling and condensation are necessary to produce synthetic process, because of the diazo reaction (coupling), diazotization and coupling reaction and condensation reaction (condensation) release a lot of heat, and the reaction conditions of ideal should be 0-5 ℃, so in the process of chemical reaction must be with lots of ice for cooling to control temperature, to ensure the quality of the products.

In pharmaceutical, chemical pharmaceutical, biochemical, pharmaceutical intermediates and fine chemical industry products production in the process of synthesis in order to control the reaction temperature, can add a lot of ice to control temperature, to ensure the quality of the products.

Traditional production mode to purchasing or homemade large pieces of ice, then crushed, add to the reaction kettle temperature control, raising the intensity of labor, the cost increase, and ice impurities, thus reduces the quality of the products.

The scale ice particles are homogeneous, highly liquid, large in contact area and fast cooling rate. Therefore, the scale ice is the ideal cooling carrier for the pharmaceutical and chemical industry.
