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 for biomass degradation material, which comprises the following steps: (1) preparing raw materials: weighing the following compositions of raw materials by weight percentage: 40 to 60 of major ingredient poly( butylene succinate), 40 to 60 of modified material polylactic acid and 0.1 to 20 of filler calcium carbonate master batch; (2) mixing the compositions to form modified poly( butylene succinate) mixture; and (3) statically placing the modified mixture at low temperature for standby application. The invention also discloses a method for manufacturing a magnetic powder catheter by adopting the raw materials, which comprises the following steps: (4) preparing a magnetic powder catheter extrusion main machine and a round die head matched with the main machine for use; (5) feeding the modified poly( butylene succinate) mixture into the extrusion main machine so as to manufacture a continuous round hollow magnetic powder catheter; and (7) cutting the continuous round hollow magnetic powder catheter into magnetic powder catheter sections. The invention also provides the magnetic powder catheter prepared by the method. The materials provided by the invention can completely degrade. The method is scientific and reasonable; the production efficiency is high; the product performance is good; and the cost is low.

Description

technical field [0001] The invention relates to biodegradable materials and products thereof, in particular to a method for manufacturing a degradable material using polybutylene succinate as the main 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 shu...
