1. Product introduction 02 02 02 02 This defoamer is one of the polyether series products of a novel polyol block copolymer successfully developed using a new synthesis process. It is a new type of defoaming agent for papermaking that can completely replace foaming enemies. This product has the characteristics of non-toxic, high efficiency, high temperature resistance, long foam suppression time, etc. Since this product contains a copolymer of ethylene glycol and propylene glycol, the defoaming speed is fast. There is foam suppression and a significant reduction in surface tension. The defoaming agent is mainly aimed at defoaming generated in the papermaking process, defoaming and suppressing the foam. This product is effective in defoaming and suppressing bubbles in the production process of newsprint and cultural paper. 2. The active ingredient 02 02 02 02 02 is a copolymer of polyether and polyether polyol. 3. Physical properties 02 02 02 02 02 02 Appearance: colorless transparent viscous liquid (25 ℃ visual inspection); specific gravity: 0.985—0.99502 02 02 acid value: ≤0.5mgKOH/g; hydroxyl value: 52-60mgKOH/g; flash point (open cup) ≥150 ℃; 02 02 02 02 viscosity: 800-1500cs ; Active substance content: 99%; Ionic type: nonionic. 4. Main use 02 02 02 02 02 It is used in paper, chemical, textile, printing and dyeing, paint, coating and other industries, with remarkable results. 5. Usage method 02 02 02 1. The dosage is 0.5-1kg per ton of dry pulp. 02 02 02. When using, the defoaming agent should be added to the emulsion of about 1% first, so that the defoaming power of the emulsion is improved, and the foam suppression time is significantly prolonged. 02 02 02 3. Add the prepared metering pump for emulsion to the sizing system or white water system continuously to achieve the effect of rapid defoaming and defoaming. 02 02 02 04. Spray can be applied to the place where a large amount of foam has formed to remove the foam. 02 02 02 05. This product is effective in defoaming and suppressing bubbles in vacuum pulping systems, paper machine copying systems, and circulating water and sewage in paper mills. 02 02 02 Taian Youxin Biotechnology Co., Ltd. has been specializing in papermaking technology research for many years.
