Description

Technical Field

[0001] The utility model relates to the field of sizing agents, in particular to a safe dispersion device for alkaline sizing agents in AKD. Background Art

[0002] Neutral sizing agent is a kind of papermaking auxiliary sizing agent. Sizing agent is a kind of papermaking additive, which can give paper and paperboard anti-ink, water resistance, emulsion resistance, corrosion resistance and other properties to improve its smoothness, strength and service life. It can be divided into internal sizing agent and surface sizing agent. Internal sizing agent is added to the pulp to delay the penetration of liquid in the paper and paperboard. Surface sizing agent generally uses anionic polymer substances and is applied to the surface of paper or paperboard after the paper sheet is formed.

[0003] The existing safe dispersion device for sizing agent disperses the sizing agent by stirring and mixing, and uses a motor to drive a stirring head to stir and disperse the sizing agent inside a dispersion box. However, the stickiness of the sizing agent may cause some of the sizing agent to adhere to the corners of the dispersion box, and the cylindrical structure of the stirring rod results in the same stirring efficiency. Subsequently, the residue inside the dispersion box needs to be cleaned, which requires other equipment for cleaning. Utility Model Content
