QB/T 1665-2004 Paper Smoothness Tester

QB/T 1665-2004 Paper Smoothness Tester

Model:PHD-01

Purpose: The technical requirements and testing methods of the Paper Smoothness Tester (Mercury-Free) (hereinafter referred to as the Smoothness Tester) comply with the international standard ISO 5627 "Paper and board—Determination of smoothness (Bekk method)" and the requirements and regulations of QB/T 1665 "Paper and board smoothness tester," making it an essential instrument for testing various high-smoothness papers. This Smoothness Tester is used for testing high-smoothness paper and board and should not be used for materials with a thickness exceeding 0.5 mm or for paper or board with high air permeability, as the amount of air passing through the sample may lead to inaccurate results.

Features:

1. LCD display, microcomputer single-chip control

2. High-precision sensor

3. Imported oil-free vacuum pump and professionally manufactured vacuum volume block and solenoid valve

4. Fully automatic control, automatic sample clamping, no manual operation required

5. Mini printer for real-time printing of test results

Technical Parameters:

1. Timer range: 1~99999s   Timing accuracy ≤ 0.1s

2. Vacuum system volume: Large volume 380±1mL  Small volume 38±1mL     

3. Effective test area: 10±0.05cm²

4. Pressure on the sample: 100±0.5kPa

5. Test working area: 50.66 kPa - 48.00 kPa

6. Sealing performance: Under a vacuum pressure of 50.66 kPa, the decrease in vacuum should be less than 3kPa within 60 minutes for the large volume or 6 minutes for the small volume.

7. Rubber pad: Thickness: 4±0.2㎜   Parallelism: 0.05㎜   Diameter: not less than 45㎜

Recovery elasticity: at least 62%    Hardness: 45±IRHD (International Rubber Hardness Degree)

8. Power supply: 220V±10%    50Hz    Power: 100W

Standard Configuration: Main unit + Mini printer

Compliant Standards: ISO 5627 "Paper and board—Determination of smoothness (Bekk method)", QB/T 1665 "Paper and board smoothness tester"
