Initial Viscosity Tester
Principle introduction
A steel ball is rolled over a sticky surface of the adhesive tape placed flat on the inclined plate, and its initial viscosity is evaluated according to the maximum size of the steel ball that the specified length of the sticky surface can stick to.
适用范围
GA-502 initial viscosity tester is suitable for the initial adhesion test of adhesive tape, protective film, 标签, plaster and other products to detect the adhesion property of the object in short contact with the product to be tested.
符合标准
国标/T 4852-2002 Test method for initial viscosity of pressure-sensitive adhesive tape (rolling ball method)
JIS Z0237-2000 Test method for pressure sensitive adhesive tape and pressure sensitive adhesive sheet

Initial Viscosity Tester
仪器特点
The test steel ball is designed in accordance with the national standard to ensure the high precision of the test data. The test tilt Angle can be freely adjusted according to the needs of users; The test principle of inclined plane rolling ball method was used to test the instantaneous adhesion of the sample.
Factory accessories

A box of steel balls A pair of tweezers
Usage method
Initial Viscosity Tester
Note of interest:
1. The machine should be kept level and stable. 2. The steel ball should be cleaned during and after the test until it is wiped clean. 3. If the ball needs to be tested again after the steel ball test, the steel ball should also be cleaned and wiped. 4. 完成测试后, the steel ball should be returned to the position, and some anti-rust oil should be sprayed in the box at intervals. 5. Please be operated by professionals to avoid improper operation and damage to the instrument.
