Testing device for preparation viscosity of flow guide coating

Abstract

The invention discloses a testing device for preparation viscosity of a flow guide coating. The testing device is characterized by comprising a sampling plate, wherein a handle is arranged at the upper part of the sampling plate; a rectangular testing zone is arranged at the lower part of the sampling plate; at least ten testing holes are formed in the testing zone from the top down; hole diameters of the testing holes are progressively increased from the top down; the adjacent testing holes are communicated by flow guide gaps penetrating through the sampling plate; and flow guide grooves which stretch to the slanting underneath and form openings on the edges are formed in the two side surfaces of the testing holes. According to the testing device, the coating is immersed into the testing zone and then taken out to observe whether the coating in the testing holes drips to allow the testing holes to be empty; construction under different conditions and operating conditions is suitable according to the empty testing holes with the minimum hole diameters corresponding to different viscosity values; whether construction is available or preparation is continued can be judged according to an observed result; and the testing device is simple and practicable.

Description

technical field [0001] The invention relates to a test tool used in the dilution of paint before spraying, in particular to a device for testing the modulation viscosity of the diversion paint. Background technique [0002] Paint is a common wall decoration material in our life, beautifying our life. In order to reduce the later transportation cost during the production of existing paint, the paint is made of special viscous, concentrated to the maximum extent for packaging, so that it can ensure When leaving the factory, the effective coating volume per unit is the smallest. After being transported to the construction site, diluent is added for preparation. For example, water is added to water-soluble coatings. At present, most coatings are water-soluble. Due to the on-site preparation, it is affected by different construction personnel and environments. Whether the prepared paint is suitable for spraying is mainly affected by its viscosity index. If the viscosity is too hi...

[0002] Paint is a common wall decoration material in our life, beautifying our life. In order to reduce the later transportation cost during the production of existing paint, the paint is made of special viscous, concentrated to the maximum extent for packaging, so that it can ensure When leaving the factory, the effective coating volume per unit is the smallest. After being transported to the construction site, diluent is added for preparation. For example, water is added to water-soluble coatings. At present, most coatings are water-soluble. Due to the on-site preparation, it is affected by different construction personnel and environments. Whether the prepared paint is suitable for spraying is mainly affected by its viscosity index. If the viscosity is too high, it is difficult to spray, and it is not suitable for self-leveling after spraying, and there will be uneven surfaces. If the paint is too diluted, it is easy to flow after spraying, and the thinner It is easy to penetrate and damage the substrate, so mastering the viscosity grade of the paint is a necessary condition for using the paint in different environments. However, the current judgment is based on the senses, and people lack on-site testing tools. These problems still need to be solved
