水性涂料檢測方法

Viscosity Measurement by Cup Method
This method involves measuring the viscosity of the water-based paint using a viscosity cup. The flow time of the paint through the cup is used to determine viscosity.

Density Measurement by Hydrometer
Density of the water-based paint can be measured using a hydrometer. The hydrometer is floated in the paint, and the reading on the scale indicates the density.

pH Measurement
The pH of the water-based paint can be determined using a pH meter or pH strips. This measurement indicates the acidity or alkalinity of the paint.

Drying Time Test
The drying time of the water-based paint can be evaluated by applying a sample to a surface and measuring the time it takes to dry completely.

Scratch Resistance Test
A scratch test can be conducted to determine the resistance of the dried water-based paint to scratching. Various tools can be used to apply pressure and assess the paint's durability.

Adhesion Test
The adhesion strength of the water-based paint can be evaluated by applying tape to the dried surface and then peeling it off to see how well the paint adheres to the substrate.

Color Measurement
The color of the water-based paint can be measured using a spectrophotometer or colorimeter to ensure consistency and accuracy in color reproduction.

Film Thickness Measurement
The thickness of the dried paint film can be measured using a film thickness gauge, which helps in ensuring the uniformity of the paint application.

Chemical Resistance Test
Chemical resistance of the water-based paint can be evaluated by exposing the dried paint film to various chemicals and assessing any changes or damage to the coating.
