PVC garden hose pipes are very common in our daily life. How are pvc garden hoses produced? Hose contains a lot of plasticizers and stabilizers and other ingredients, so pay attention to the following steps when making pvc garden hose.
First prepare all the materials for making the pvc garden hose, determine the appropriate corresponding amount according to the recipe, and pour the prepared materials into the mixer at one time in a certain order.
The correct order is PVC resin, plasticizer, stabilizer, lubricant and remover, generally knead the material for 45~50 minutes, and take out the material when the temperature is 100~110 degrees Celsius.
Then the next granulation can be carried out, pay attention to the temperature adjustment when the PVC garden hose pipe is granulated, the high point of the material temperature should be kept below the extrusion tube forming temperature, not below the melting degree of the material.
The second is molding. The transparency of the pvc garden hose is closely related to the molding temperature. Therefore, mastering the mold temperature is the key. If the temperature is slightly higher, the transparency of the formed pvc garden hose is relatively high.
The next step is traction. The speed of traction and the speed of cooling will affect the transparency of the pvc garden hose. If the pulling speed is slightly larger, the cooling speed will be faster, and the transparency of the PVC garden hose pipe will be higher.
After the traction is completed, it is crimped and packaged. After that, as long as the quality inspection is passed, the finished garden hose PVC is completed and can be put on the market for sale.
The above content is the production process of PVC garden hose pipe shared today. If you understand how the pvc garden hose is produced, then you can also have a certain understanding of some of its qualities, and you can more clearly understand and distinguish the advantages and disadvantages when purchasing.
1. Odor is the key. The odor of inferior pvc garden hose products has strong persistence and fat solubility, which will harm the liver and nervous system. Therefore, when choosing products, pay great attention to the smell of pvc garden hose products.
2. The product has poor compressive effect and poor bonding strength. It is easy to become hard in cold weather, and PVC garden hose pipe is easy to break. Although some products are soft, it is because of the addition of cold-resistant plasticizers in production. The product has certain harm to the human body.
3. Observe the quality of the polyester material used for the braided layer. If it is inferior, there will be a problem of poor adhesion of the inner, outer and middle braided layers, and peeling problems, which will affect the working pressure and service life of the PVC garden hose pipe product.
