(2) The purpose, method and characteristics of hardness testing

 

3. Method for detecting film roll hardness
1 selection of testing equipment
There are various instruments for detecting the hardness of an object, but so far there has not been a hardness tester that professionally detects the hardness of a film roll. Due to the large difference in surface hardness between various objects and the variety of hardness testers, it is important to select a hardness tester that can effectively reflect the tightness of the film roll. After screening and comparison, our company has determined the "A-type rubber hardness tester" for detecting the surface hardness of rubber products as an auxiliary instrument for detecting the tightness of the film roll.
2 detection instrument correction
Since the "A type rubber hardness tester" is not a special test instrument for the film roll, in order to improve the detection accuracy of the instrument, we have modified the structure of the hardness tester according to the characteristics of the film, and increased the presser area by 5 times.
3 detection methods a.
Before the test, the pointer of the hardness tester should be in the free state and point to the zero position. When pressing the hardness tester on the glass plate, the pointer should be 100 degrees (the end face of the press pin and the bottom of the foot are in close contact with the glass). If the zero position and the 100 degree are not indicated, the needle can be pressed slightly several times, if not When referring to zero and 100 degrees, it cannot be used. The hardness tester to be confirmed can be used again if it meets the requirements for use. b.
When testing the hardness, put the hardness tester on the side of the film product, take the left, middle and right positions, at least 40mm from the edge of the film roll, and firmly press the end of the hardness tester with both hands, so that the pressure pin is pressed vertically. The sample is read within 1 s until the pressure is fully contacted with the sample, and the average is taken and recorded.

(iv) Effect of film roll tightness on product quality

(5) Coping methods
1. Reasonable principle: Applicable is reasonable, which means that the cutting operator and the quality inspector are too loose according to the winding/
Too tightly influence the degree of influence on different products, adjust the cutting process reasonably, and reasonably grasp the tightness of the film roll to meet the requirements of the use of film products.
2. Ningsong Motight principle: objective when cutting equipment status, product specifications, film performance characteristics, etc.
When the influence of the condition causes the winding tightness to be in an inappropriate degree, the principle of tightness is generally used, because the problem of over-tightening often makes the film unusable, except for the special requirements.
3. The principle of primary and secondary: it means that in the process of slitting production, small groups should be followed to the interests of large collectives.
The principle of benefiting the interests of the company, avoiding the pursuit of high output and high distribution for the purpose of reducing the quality of cutting, all should be based on product quality, maintaining the German crown film brand as the responsibility, effectively completing various production and quality indicators Effectively serve the enterprise and users, and strive to be the best supplier of film.
4. System Management Principles: Refers to the use of systematic, scientific management methods, practical, theoretical, and empirical
The accumulated cutting control method is compiled, and according to the optimal combination of different types of products, width, winding length, season and other external variables and slitting tension, pressure and other internal variables, the document control management is performed to form an operation guidance document. Minimize the influence of subjective factors, reduce the impact caused by insufficient individual ability or excessive dependence on experience, and continuously supplement, optimize and improve the operation guidance documents to meet the needs of system management.
