Overview
The MIT folding strength tester is a testing tool used to detect the fatigue performance of paper, through which the number of folding times and folding resistance of paper can be detected. The instrument can also be used for the fatigue performance detection of Spinning & weaving products, Plastic film, wire rod and other products. It is a professional testing tool for paper manufacturers, Encasement manufacturers, Spinning & weaving products manufacturers, wire rod manufacturers and other products to detect product mass.
Features
1. Easy to use
Adjustable between 20 and 200 double folds per minute
3. Use the weight of the corresponding tension to compress the spring to achieve the required tension
4. Color touchscreen, easy to operate
Principle
The MIT folding tester places a bendable sample under a constant tension load and then folds the sample in either direction to a 135 ° angle at a rate of 175 double folds per minute until the sample breaks at the crease. The instrument can be adjusted between 20 and 200 double folds per minute, with a maximum allowed fold angle of 135 degrees.
Applications
Paper, Cardboard, Tissue Paper, Plastic film, Metal foil, Miscellaneous, Film thickness less than 1mm sheet material
Standards
GB 457、GB 2679.5、QB 1049、ISO 5626、TAPPI T 511、ASTM D2176、BS ISO 5626
Notice
• Sample size should be 15mm wide and longer than 140mm
• The folding angle needs to be controlled within the range of 135 ° +/- 2 °
The folding speed should be maintained at 175 +/- 10cpm.
The tension range should be adjustable between 4.9N, 9.81N, and 14.7N
• The width of the clip should be kept at 15 +/- 0.1mm
• The fillet radius of the folding mouth should be R0.38mm +/- 0.02mm
• The gap distance of the folding mouth can be selected from 0.25mm, 0.50mm, 0.75mm, 1.00mm.
• Power supply voltage should be 220VAC, 50Hz
