Abstract

The invention provides a higher aliphatic alcohol emulsion antifoaming agent. The antifoaming agent is prepared from rice bran wax, ax, alkane or vegetable fat, a surfactant, a thickening gent, a bactericide and water, and the rice bran wax is the active component of the emulsion antifoaming agent. The rice bran wax takes higher aliphatic acid, higher aliphatic alcohol and higher aliphatic alcohol ester as main components and contains abundant hexacosanol, octacosanol, triacosanol and corresponding alcohol ester. The higher aliphatic alcohol emulsion prepared from the rice bran wax is applicable to foam control in each section of pulping and papermaking, particularly a papermaking system and foam control of papermaking wet-ends.

Description

technical field

[0001] The invention belongs to the technical field of pulping and papermaking, in particular to a high-grade fatty alcohol emulsion defoamer. Background technique

[0002] The pulp and paper system is a complex multiphase system. The fiber raw material itself contains a lot of resinous substances. At the same time, in order to improve the running performance of the paper machine and the performance of the paper, various additives are added during the production process, such as sizing agent, retention and drainage aid, resin control agent, strengthening agent, desorbing agent, etc. These substances have certain surface activity. In the process of pulp and paper making, especially in the wet end of paper making, it is very easy to generate foam. The generation of foam will not only cause the foam to overflow in the tank and reduce the water filtration capacity of the paper material, but also increase the power consumption in the process of paper material fl...
