Problems solved by technology

However, due to the special properties of nanofiltration membranes, this device is not suitable for measuring the adhesion of nanofiltration membranes
There are still many such patented technologies or proprietary technologies, but none of them have targeted structural design for the characteristics of nanofiltration membranes, so it is difficult to test the adhesion of nanofiltration membranes
For now, within the scope of the applicant's search, there are no literature reports on products or methods that specifically test the adhesion of nanofiltration membranes

Embodiment Construction

[0011] The principles and advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, a nanofiltration membrane adhesion test device includes a pressure gauge with a pressure relief valve, one end of the pressure gauge is connected with a compressed air quick connector, and the other end of the pressure gauge is connected with a connector, an upper end cover , an O-ring, a support net and a diaphragm sealing and pressure-bearing system composed of a base for placing the diaphragm to be tested. Wherein, the connector has an internal thread, and the upper end cover is provided with an external thread matched with the connector, and the upper end cover, the connector, the O-ring and the supporting net are closely matched to make the base part form a sealed space. The main functions of each component are: compressed air quick connector, used to connect compressed air to pr...

Abstract

The invention discloses an adhesion force testing device for a nanofiltration membrane. The device comprises a pressure gauge with a pressure reducing valve; one end of the pressure gauge is connected with a compressed air fast joint; and the other end of the pressure gauge is connected with a sealed pressure bearing system composed of a connector, an upper cover, an O type sealing ring, a support network and a seat for placing a diaphragm to be tested. The invention overcomes the defect of difficulty in measuring adhesion force of nanofiltration membrane of an existing adhesion force test device, not only can effectively test adhesion force of the nanofiltration membrane but also has advantages of simple manufacture and convenient operation.

Description

technical field [0001] The invention relates to a test device, in particular to a test device which can be used to measure the adhesive force of a nanofiltration membrane. Background technique [0002] Nanofiltration membrane is a new type of separation membrane developed in recent years. Nanofiltration membrane is a new type of separation membrane developed in recent years. The composite nanofiltration membrane has been widely used in food, chemical, pharmaceutical, water treatment and other fields. The amount is greatly improved; the thick porous support layer provides the high strength necessary for the membrane to be used under certain pressure conditions. The adhesion between the functional layer and the base membrane is the basic premise to ensure that the functional layer of the nanofiltration membrane meets various performance requirements. In terms of evaluating the quality of the composite membrane, the degree of adhesion between the functional layer and the base...
