코팅산업에서는, 점도가 핵심 매개변수입니다., which directly affects the fluidity and coating performance of coatings. 그러므로, accurate determination of the viscosity of coatings is essential for production and quality control. This article will introduce a common method, namely the Zeen viscosity cup method, used to determine the viscosity of coatings.

1. 범위 및 설명

Zayn viscosity cup, also known as Zayn viscosity cup, is a tool commonly used in the determination of paint viscosity. It has a wide range of applications and can quickly and easily determine the viscosity of coatings in the laboratory and on the construction site. The characteristic of the Zeen cup is that it can be dipped into the test liquid and can be used regardless of whether the liquid is hot or cold. The viscosity of the liquid is measured in Zahn No# seconds based on the time it takes for the filament flowing out of the cup to break.

2. 기기 및 재료

In order to determine the viscosity of coatings, 다음 도구와 재료가 필요합니다:

Zeen Viscosity cup: Volume is (44±1) 밀리리터.

온도계: The range is 0°C to 50°C, the index is 0.2°C.

스톱워치: The division is 0.2 초.

3. 판정방법

Here are the steps for determining paint viscosity with Zeen Cup:

첫 번째, stir the liquid to be measured thoroughly and measure its temperature.

Hook the small ring on the handle of the viscosity cup with your finger and immerse the cup body in the liquid for 1 에게 5 minutes to achieve thermal balance.

그 다음에, quickly and smoothly pull the viscosity cup vertically out of the liquid, starting the timing immediately when the upper edge of the cup body comes out of the liquid level.

During the process of liquid discharge, ensure that the viscosity cup is no more than 150 mm away from the liquid surface. Stop timing when the first break point occurs in the steady stream filament flowing from the small hole at the bottom of the cup.

4. 결과발표

The result of the measurement is expressed as the time of liquid outflow (초). The difference between the two measurements should be less than 5% 평균의.

5. Instrument description

The Zeen Viscosity cup is a bullet-shaped stainless steel cup with corrosion and solvent resistance. There is a precise hole in the bottom of the cup, and the volume is 44 밀리리터. Zeen viscosity cups are available in various sizes with different bore sizes and can be used to measure liquids ranging from 5 to 1800mm²/s. 표 참조 1 for specific technical parameters.

Zeen viscosity cup is an outflow type viscometer, so the measured number of seconds can be calculated by a specific constant k and c to calculate the motion viscosity, the specific calculation formula is: v = k(t-C), where v represents the motion viscosity (mm²/초), t represents the outflow time (초), k and c are the corresponding constants.

요약하자면, the method of determining paint viscosity by Zeen Cup is a common and effective measurement technique that can be used for viscosity control and quality assessment in the paint industry. By accurately determining the viscosity of the coating, 제조업체는 제품의 일관성과 성능을 보장할 수 있습니다., thereby improving the production efficiency and quality of the coating.
