Problems solved by technology

[0010] As a supporting product for magnetic particle testing tools, magnetic powder catheters have a large market demand and consumption. There are incomplete statistics. At present, the plastic magnetic powder catheters used in the world every year are more than 10,000 tons, while the traditional plastic magnetic powder catheters are mainly made of polymer. Propylene (PP) is used as a raw material, which cannot be degraded after use; as the society pays attention to white pollution and the improvement of people's environmental awareness, in the near future, magnetic powder catheters made of traditional plastics will be generally restricted by countries all over the world. It is easy to produce, has a wide range of sources of materials, is easy to decompose after use without polluting the environment, and has performances close to that of plastic catheter replacement products will become the mainstream of future development

Abstract

The invention provides a preparation method of a high-transparency degradable material. The method is characterized by comprising the following steps of: (1) preparing raw materials, namely weighing the following raw material components in percentage by weight: 95-98 percent of polypropylene resin, 1-5 percent of polystyrene resin, 0.01-0.05 percent of food-grade benzoic acid and 0.1-0.5 percent of modified paraffin; (2) mixing the components to obtain a polypropylene resin modified mixture; and (3) standing the modified mixture at low temperature for later use. The invention also discloses a method for manufacturing a magnetic powder conduit by using the material. The method comprises the following steps of: (4) preparing a magnetic powder conduit main extruder and a circular die head used together with the main extruder; (5) feeding the modified mixture into the main extruder to obtain a continuous circular hollow magnetic powder conduit; and (7) cutting the obtained continuous linear magnetic powder conduit into magnetic powder conduit sections. The invention also provides the magnetic powder conduit manufactured by the method. The material provided by the invention is highly transparent and degradable. The method is scientific and reasonable, and has high production efficiency, high product performance and low cost.

Description

technical field [0001] The invention relates to degradable materials and products thereof, in particular to a manufacturing method of a highly transparent degradable modified polypropylene resin material and a magnetic powder catheter prepared by using the material. Background technique [0002] Magnetic particle testing is used to detect cracks and other defects on or near the surface of ferromagnetic materials (including iron, nickel, diamond, etc.). In recent years, magnetic particle testing has developed into one of the five conventional techniques of nondestructive testing, and is widely used in the pressure vessel and boiler manufacturing, chemical industry, electric power, shipbuilding, aviation and aerospace industries and other departments of important load-bearing structures and parts of the surface and Near surface quality inspection. [0003] The principle of magnetic particle testing is that when the workpiece is magnetized, if there are cracks, cold shuts and ...
