Product Specification

XJW-90 Model Rubber Extruder And Hot Air Vulcanization Box For Rubber Water Hose Production
 

Production Process:

 

The following is the process flow of combining rubber hose extruder with hot air vulcanization:

1. Raw material preparation

- Prepare suitable rubber raw materials and add various additives such as vulcanizers, accelerators, fillers, etc. according to product requirements.

2. Extrusion molding

- Put the mixed rubber raw materials into the barrel of the rubber hose extruder.

- The screw in the extruder rotates, shears, squeezes and pushes the rubber, so that it is extruded through the die head mold to form an unvulcanized rubber hose.

3. Initial cooling

- The temperature of the newly extruded rubber hose is relatively high, and it is moderately cooled through a preliminary cooling device (such as a water cooling tank) to make it initially fixed.

4. Hot air vulcanization

- Send the rubber hose after preliminary cooling to the hot air vulcanization equipment.

- The hot air blower in the vulcanization equipment generates high-temperature hot air, so that the rubber hose undergoes vulcanization reaction under certain temperature and time conditions.
5. Secondary cooling

- After vulcanization, the rubber tube passes through a secondary cooling device (such as air cooling or water cooling) to quickly cool it to room temperature to fix the physical properties and dimensions after vulcanization.
6. Pulling and winding/cutting

- Use a pulling device to pull the rubber tube at a uniform speed to ensure its straightness and dimensional accuracy.
- According to the final requirements of the product, the rubber tube is rolled into a roll or cut to a fixed length.
7. Quality inspection

- Perform an appearance inspection on the vulcanized rubber tube to check for defects such as flaws, bubbles, deformation, etc.
- Perform physical property tests such as tensile strength, hardness, aging resistance, etc. to ensure that the product meets quality standards.
8. Packaging and storage

- Qualified rubber tubes are packaged to protect the product from damage and contamination during transportation and storage.
- Store in a dry, well-ventilated warehouse, away from direct sunlight and humid environment.

In the entire process, it is necessary to strictly control the process parameters of each link, such as extrusion temperature, extrusion speed, vulcanization temperature, vulcanization time, cooling speed, etc., to ensure the quality and performance of the rubber tube.

Technical parameter:

Advantages of hot air vulcanization include:

1. Uniform heating: Hot air can be more evenly distributed in the vulcanization chamber, so that rubber products are heated evenly, so as to ensure the consistency of vulcanization quality.
2. Wide range of application: It can be used for vulcanization of rubber products of various shapes and sizes, and can also be better treated for products of complex shapes.
3. The equipment is relatively simple: compared with some other vulcanization processes, the structure and operation of hot air vulcanization equipment is relatively simple and the cost is low.
4. Easy to control: By adjusting the temperature, wind speed and time of the hot air, the vulcanization process can be controlled more accurately.
5. Environmental protection: Usually does not produce a lot of pollutants, relatively friendly to the environment.
