Abstract

The invention discloses a adhesive dipping component and device for testing the viscosity of a soy-based formaldehyde-free wood adhesive. The adhesive dipping component is formed by connecting more than one square hard sheet, which does not bend in the process of lowering below the liquid level of the soy-based formaldehyde-free wood adhesive, in a cross mode; cross connecting lines are parallel to the vertical side lines of the square hard sheets; a cut-off line, through which the dipped soy-based formaldehyde-free wood adhesive is positioned on a same horizontal surface of the adhesive dipping component, is arranged on each hard sheet. The adhesive dipping device comprises a container filled with the adhesive, the adhesive dipping component, a pulley component which lifts the adhesive dipping component to be completely separated from the liquid level of the soy-based formaldehyde-free wood adhesive so as to apply a stable external force, and a weight component which is matched with the pulley component to apply the stable external force to the adhesive dipping component so as to ensure that the dipping component stably descends or ascends. The viscosity index of the soy-based formaldehyde-free wood adhesive is effectively and quantitatively characterized and tested through the average adhesive dipping amount in unit area.

Description

technical field [0001] The invention relates to a viscosity testing device, in particular to a glue-dipping component and a testing device for testing the viscosity of soybean-based formaldehyde-free wood adhesives. Background technique [0002] When a liquid is flowing, the property of internal friction between its molecules is called the viscosity of the liquid, and the size of the viscosity is expressed by viscosity. Viscosity is an important indicator to measure the fluidity of a liquid, and it is one of the important physical properties and technical indicators of a liquid. The viscosity of the liquid is restricted by the viscosity, the stronger the viscosity of the liquid, the higher the viscosity value. In the fields of chemical industry, food and biomedicine, the viscosity of liquid involves the process, equipment, efficiency and product quality of many industrial processes, and is also closely related to human life and health. Viscosity reflects the basic characte...
