As an important component widely used in various industrial fields, the production process of steel wire braided rubber hoses involves multiple key elements that directly affect the quality and performance of the hoses. The following are several core elements that should be noted in the production of steel wire braided rubber hoses:

1、 Raw material selection and preparation

The main raw materials for steel wire braided rubber hoses include high-quality synthetic rubber and steel wire. The rubber part needs to have good elasticity, wear resistance, and corrosion resistance to ensure that the hose can maintain stable performance in various environments. Steel wire requires high strength and toughness to support the use of rubber hoses in high-pressure environments.

When choosing rubber raw materials, high-performance materials such as EPDM rubber are usually considered, which have good weather resistance and chemical stability. The selection of steel wire should pay attention to its tensile strength and fatigue resistance, ensuring that it is not easily broken or deformed during use.

The preparation process of raw materials includes the mixing of rubber and the pretreatment of steel wire. Rubber mixing is the process of thoroughly mixing various rubber compounding agents with raw rubber in a mixer to obtain a uniformly performing rubber material. During the mixing process, it is necessary to strictly control parameters such as temperature, time, and pressure to ensure the stable quality of the rubber material. Steel wire pretreatment includes steps such as cleaning, rust removal, and coating with rust inhibitors to improve the corrosion resistance of the steel wire and its adhesion to rubber.

2、 Squeeze out the inner and outer adhesive layers

Squeezing the inner and outer rubber layers is an important step in the production process of steel wire braided rubber hoses. The inner rubber layer is in direct contact with the medium, so it needs to have good sealing and corrosion resistance. The outer rubber layer serves to protect the steel wire layer and further improve the wear resistance and corrosion resistance of the rubber hose.

During the extrusion process, it is necessary to ensure that the temperature, pressure, and extrusion speed of the rubber material are controlled within a reasonable range to ensure that the extruded adhesive layer has a uniform thickness, smooth surface, and no defects such as bubbles and impurities. To achieve this goal, precision extrusion heads and advanced extrusion processes are usually used to ensure uniform flow and stable extrusion of the rubber material.

3、 Wire weaving and winding

Steel wire weaving is one of the core steps in the production of steel wire woven rubber hoses. The weaving process involves weaving steel wires onto the inner rubber layer at specific angles and densities using a weaving machine to enhance the strength and pressure resistance of the hose. During the weaving process, attention should be paid to the uniformity of the tension of the steel wire to avoid loose or overly tight situations.

The weaving density and angle of steel wire have a significant impact on the performance of rubber hoses. Higher weaving density and appropriate weaving angle can improve the compressive strength and wear resistance of rubber hoses. At the same time, it is necessary to ensure good adhesion between the steel wire and the inner rubber layer during the weaving process to improve the overall strength and sealing of the rubber hose.

For certain special purpose steel wire braided rubber hoses, such as high-pressure oil pipes or high-temperature oil pipes, special weaving processes and materials are also required to meet higher performance requirements.

4、 Sulfurization treatment and quality control

Sulfurization treatment is a key process in the production of steel wire braided rubber hoses. Sulfurization is the process of placing the formed rubber hose into a vulcanization tank and conducting a chemical reaction under certain temperature, pressure, and time conditions, causing rubber molecules to undergo cross-linking reactions, thereby improving the physical properties and chemical stability of the hose.

During the vulcanization process, it is necessary to strictly control parameters such as vulcanization temperature, time, and pressure to ensure the vulcanization effect of the rubber hose. The vulcanized rubber hose still needs to undergo inspection and testing, including visual inspection, size measurement, pressure testing, and performance testing, to ensure that its various performance indicators meet the standard requirements.

In terms of quality control, in addition to strict inspection of raw materials and semi-finished products, real-time monitoring and recording of the entire production process are also required. By adopting advanced testing equipment and quality control methods, problems in the production process can be detected and corrected in a timely manner, ensuring the stability and reliability of product quality.

5、 Production equipment and process optimization

The production equipment and process of steel wire braided rubber hoses have a significant impact on product quality and production efficiency. Modern production equipment typically includes key equipment such as mixers, extruders, braiding machines, and vulcanization tanks. These devices need to have characteristics such as high precision, high stability, and high degree of automation to meet the needs of large-scale production and high-quality requirements.

In terms of process optimization, the production efficiency and quality stability of products can be improved by improving extrusion processes, weaving processes, and vulcanization processes. For example, by adopting advanced extruder heads and mold designs, the flow state and extrusion quality of the rubber material can be optimized; By using precision weaving machinery and control systems, the accuracy and uniformity of weaving can be improved; By adopting advanced vulcanization technology and equipment, the vulcanization time can be shortened and the vulcanization effect can be improved.

6、 Environmental Protection and Safety Production

In the production process of steel wire braided rubber hoses, environmental protection and safety production are also important aspects that cannot be ignored. The waste gas, wastewater, and solid waste generated during the production process need to be effectively treated and recycled to reduce pollution and damage to the environment. At the same time, it is necessary to strictly comply with safety production regulations and operating procedures during the production process to ensure the safety and physical health of employees.

In order to achieve environmental protection and safety production goals, enterprises can take a series of measures, such as strengthening the construction and management of environmental protection facilities, promoting clean production technologies, and improving employees' safety awareness and operational skills. By implementing these measures, environmental pollution and safety risks in the production process can be effectively reduced, and the sustainable development capability and market competitiveness of enterprises can be improved.

The key factors to consider in the production of steel wire braided rubber hoses include raw material selection and preparation, extrusion of inner and outer rubber layers, steel wire braiding and winding, vulcanization treatment and quality control, optimization of production equipment and processes, as well as environmental protection and safety production. These elements are interrelated and influence each other, jointly determining the quality and performance of steel wire braided rubber hoses.
