Abstract

The invention relates to the technical field of defoamers, in particular to a defoamer for papermaking. The defoamer comprises, by weight, 5-8 parts of silicone grease, 10-15 parts of polyether, 1-3 parts of sodium dodecyl sulfate, 1-3 parts of sodium chloride and 2-4 parts of cosolvent. The defoamer can meet defoaming needs and is good in using effect when in use.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a defoamer for papermaking. Background technique [0002] All defoamers are needed in the papermaking process, but the current defoamers cannot meet the use requirements when they are used. Contents of the invention [0003] In order to overcome the shortcomings of existing defoamers, the invention provides a defoamer for papermaking. [0004] The technical solution adopted by the present invention to solve the technical problem is: a kind of defoamer for papermaking, comprising: 5-8 parts of silicone grease, 10-15 parts of polyether, 1-3 parts of sodium lauryl sulfate Parts, 1-3 parts of sodium chloride, 2-4 parts of co-solvent. [0005] According to another embodiment of the present invention, it further includes that the optimal number of silicone grease is 6 parts. [0006] According to another embodiment of the present invention, it further includes that the optimal n...
