Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to an improved device for testing the water absorption performance of superabsorbent resin. Background Technology

[0002] Superabsorbent polymers (SAPs) are newly developed functional polymer materials containing strong hydrophilic groups and a certain degree of cross-linking. Previously used absorbent materials, such as paper, cotton, and linen, have a water absorption capacity of only 15 to 40 times their own weight (referring to deionized water, the same below), and their water retention capacity is also quite poor. SAPs, with their hydrophilic groups, can absorb large amounts of water and swell while retaining the water from leaking out. Examples include starch-grafted acrylates, grafted acrylamide, highly substituted cross-linked carboxymethyl cellulose, cross-linked carboxymethyl cellulose grafted acrylamide, and cross-linked hydroxyethyl cellulose grafted acrylamide polymers. They can generally absorb more than 100 times their volume of water, with the highest absorption rate reaching over 1000 times. They are commonly used as medical materials, such as diapers and sanitary napkins, and are also used industrially as leak-sealing materials. SAPs are generally high-molecular-weight electrolytes containing hydrophilic groups and cross-linked structures. Before absorbing water, the polymer chains entangle and cross-link to form a network structure, thus achieving overall compactness.

[0003] Patent number CN217385502U discloses a novel superabsorbent polymer (SAP) water absorption performance testing device, relating to the field of water absorption performance testing technology. The device includes a testing device body, a base frame, and a vibration platform. The testing device body further includes a base frame installed at the bottom. A support frame is fixedly connected to the top of one side of the base frame. A funnel is installed on the inner wall of the support frame, and an infrared rangefinder is fixedly connected to the inner wall of the support frame. A water tank is installed on the top of the base frame, and a water pump input is fixedly connected to the top of the water tank. A water outlet pipe is installed on the output end of the water pump. A vibration platform is installed on the top of the base frame, and a fixed seat is installed at the top of the vibration platform. A fixing groove is formed on the outer surface of the top of the fixed seat.

[0004] The above has the following shortcomings: Although the water tank can be easily cleaned by separating it, it is necessary to lift the water tank by hand to remove it, but the water-absorbing resin is very heavy and difficult to lift. Utility Model Content
