● Cardboard pressure tester ● knowledge:

Raw paper performance test.

Since the general carton factory does not have the conditions for temperature-controlled room testing and the timeliness of the inspection is taken into consideration, normal testing should be adopted. As long as there is no obvious defect on the surface of the roll paper, it can be sampled in the second layer, and the technical indicators such as the quantitative, ring crush strength, burst strength, crack length, and water absorption can be measured according to the methods proposed by relevant national standards. Quantitative inspection is mainly to see if there is overweight or grammage insufficient; ring pressure strength and burst strength test is the most critical, test results using regression analysis, and then refer to the two sides agreed, you can know whether or not qualified; test crack length is mainly Understand the tensile strength of the base paper, which can be used as the main basis for the application of tile line; water absorption determines the adhesive properties of the base paper, printing performance, the severity of the impact of atmospheric moisture, and so on. Other aspects, such as tightness, smoothness, folding resistance, flat compressive strength, oil permeability, etc., are determined according to specific needs.
