Abstract

The invention provides a preparing device for a magnetic nondestructive testing material based on the membrane technology. The preparing device comprises a first storage tank, a second storage tank, a first pump, a second pump, a reaction container, a first membrane assembly and a second membrane assembly. A liquid outlet of the first storage tank is communicated with a liquid inlet of the first membrane assembly through the first pump, a liquid outlet of the first membrane assembly is communicated with a liquid inlet of the first storage tank, a liquid outlet of the second storage tank is communicated with a liquid inlet of the second membrane assembly through the second pump, and a liquid outlet of the second membrane assembly is communicated with the second storage tank. The first membrane assembly and the second membrane assembly are arc and are symmetrically arranged in the reaction container. The invention further provides a preparing method for the magnetic nondestructive testing material based on the membrane technology.

Description

technical field [0001] The invention relates to the technical field of nondestructive testing, in particular to a nano Fe 3 o 4 A device for preparing a magnetic non-destructive testing material and a preparation method thereof. Background technique [0002] Non-destructive testing is to use the sound, light, magnetic and electrical characteristics of the material to detect whether there is a defect or inhomogeneity in the object to be inspected without damaging or affecting the performance of the object to be inspected, and to give the size and location of the defect. , nature and quantity information. Superparamagnetism is a special magnetic effect. Substances with superparamagnetism are magnetized when an external magnetic field is applied. When the external magnetic field disappears, the magnetization of superparamagnetic substances is almost zero and the coercive force is very small. Due to this characteristic, superparamagnetic materials are used in many fields. Am...
