Company information
The company's main import and export products include
(1)Flavors and Fragrances:Fragrance is a substance that can be smelled by the sense of smell or tasted by the sense of taste, and is used as an ingredient in the preparation of flavours. In addition to individual varieties, most fragrances cannot be used alone. Flavour is the raw material that gives cosmetics a certain aroma, it is one of the key raw materials in the manufacturing process.
(2)Water Treatment:The way of water treatment includes physical treatment and chemical treatment. Human water treatment methods have been quite a few years of history, physical methods, including the use of a variety of different pore size of the filter material, the use of adsorption or barrier way, the impurities in the water outside, adsorption method in the more important for the adsorption of activated carbon, barrier method is to pass the water through the filter material, so that the impurities of a larger size can not pass, and thus obtain cleaner water.
