Problems solved by technology

The tensile strength of a single structure is insufficient, while the diameter of the wire wound by multiple filaments is relatively thick, and it is easy to pill and fluff in subsequent processing, and the performance and structure are unstable and easy to shrink.

Embodiment Construction

[0020] The preferred implementation of the production process of the sandwich development line of the present invention will be described below with reference to the accompanying drawings.

[0021] figure 1 and figure 2 The specific implementation of the production process of the sandwich developing wire of the present invention is shown: the sandwich developing wire includes a core wire and an outer layer material, and the production process of the sandwich developing wire is as follows:

[0022] (1) The modified particles are melted, and the extrusion temperature is 200°C;

[0023] (2) put the core wire;

[0024] (3) lead wire, and preheat the core wire to 200°C;

[0025] (4) Carry out the sandwich injection molding process, and inject the outer layer material;

[0026] (5) Sandwich coating the core wire with the outer layer material;

[0027] (6) cooling and drying the sandwich developing line;

[0028] (7) Take up the sandwich developing wire.

[0029] The producti...

Abstract

The invention discloses a production process of a sandwiched developing line and relates to the field of medical equipment and functional wire rods. According to the production process of the sandwiched developing line disclosed by the invention, a special injection molding sandwiched process is adopted, so that the outer layer structure has a developing function, and the core wire has relatively high tensile strength. The developing line prepared by the injection molding sandwiched process is high-temperature-resistant, low-temperature-resistant, ultrahigh in tensile strength and good in developing effect. By means of properties of different materials, sandwiched wire rods combined in different properties can be obtained.

Description

technical field [0001] The invention relates to the fields of medical equipment and functional wires, in particular to a production process of a sandwich developing wire. Background technique [0002] During the operation, it is necessary to use imaging fibers to check surgical gauze, surgical towels, medical catheters and other medical dressings left in the patient's body. Traditional imaging fibers only have a single structure or are wound with multiple silk threads. The tensile strength of a single structure is insufficient, while the wire diameter formed by winding multiple wires is relatively thick, and it is easy to pill and fluff in subsequent processing, and the performance structure is unstable and easy to shrink. [0003] The traditional sandwich injection molding process is only applied to the metal core as the core wire material. This kind of technology is modified to be suitable for the core wire to be made of special fibers and polymer modified fibers, etc., an...
