How is PVC hose produced?
The hose contains a large amount of plasticizer and some stabilizers and other ingredients, and there are several steps to go through during production.
First of all, all the materials to make PVC hose are prepared, and the corresponding weight is determined according to the recipe. Pour the prepared materials into the kneader in a certain order at a time. The correct order is: PVC resin, plasticizer, stabilizer, lubricant, colorant. In general, the material needs to be kneaded for 45 to 50 minutes at a temperature of 100 to 110 degrees Celsius to remove the material.
Then you can granulate, in the process of PVC hose granulation must pay attention to the control of temperature, the highest point of the material temperature is not lower than the melting degree of the material, but also maintain lower than the extrusion molding temperature.
Next, the transparency of the hose is closely related to the forming temperature, so grasp the forming temperature is the key, the temperature is slightly higher, the transparency of the PVC hose will be relatively high.
Next is traction, traction speed and cooling speed will affect the transparency of the hose, traction speed is slightly higher, cooling speed is faster, the transparency of the hose will be higher.
After the traction is completed, the coil is rolled and packed, and once the quality inspection is passed, the finished PVC hose is completed and ready for sale.
The above content is today to share the PVC hose production process, understand how the PVC hose is produced, then some of its quality can also have a certain understanding, at the time of purchase can more clearly understand and respectively advantages and disadvantages.
