Features
①It is chemically inert and will not react with other foaming substances. ②Physiologically inert, non-toxic, non-polluting, and harmless to the environment; ③It has excellent defoaming performance with low dosage. ④Wide temperature range, outstanding heat and cold resistance, weather and aging resistance.
⑤ It has excellent softness and lubricating properties, which is beneficial to improve the quality of coated paper. However, the relatively high price of silicone products makes some manufacturers unacceptable, resulting in the current silicone defoamers are not widely used. In fact, from the point of view of dosage, due to the small dosage of silicone, usually only need to add the mass fraction of the system 1~75×10-6 to achieve good defoaming effect. If it is used in combination with other defoamers, it can further lower the cost. Comprehensive consideration, the use of silicone as a defoaming agent compared with other defoaming agents, the cost will not increase. With the continuous improvement of organic silicon synthesis technology and the continuous reduction of raw materials, the problem of high price of organic silicon can certainly be solved, so defoamers containing organic silicon will be a hot spot in the paper-making market.
