Abstract

The invention provides a device for detecting the liquid absorption performance of a paper pulp molding material. The device comprises a control module, a detection cylinder, a sealing gasket, a bottom plate, a supporting frame, an electromagnet, a peristaltic pump, a liquid storage tank, an air cylinder, a squeezing block, a water absorption material and a balance. The device can detect a pulp molding sample with a small size (the diameter is 3-5.5 cm), the peristaltic pump is controlled by the control module to feed and pump liquid, the bottom plate and the detection cylinder are sealed by the electromagnet, water adsorbed on the surface of the pulp molding sample is removed by pressing of the air cylinder, the complexity of detection steps is reduced, and the measurement precision is improved. Therefore, the device has the characteristics of high measurement precision and simplicity and convenience in operation.

Description

technical field [0001] The invention relates to a device for measuring the liquid absorption performance of pulp molding materials. Specifically, it relates to a device for measuring the liquid absorption performance of pulp molding materials based on a gravimetric method. It belongs to the field of liquid absorption performance measurement. Background technique [0002] Plastic products have been widely used in the field of packaging due to their low cost and excellent packaging performance, but environmental issues such as their refractory degradation are also increasingly emerging. With the in-depth understanding of the environmental protection of plastic packaging products, in recent years, countries have introduced plastic restriction policies one after another. Pulp molded products have become one of the green packaging materials with the most potential to replace plastic products in the packaging market due to the advantages of renewable raw materials, degradable pr...
