PVC hoses are very common in our daily life, and because of the economical benefits, general home decoration can use it. PVC pipes are mainly divided into hoses and hard pipes. The hard tube occupies a larger market share than the hose, and the PVC hose generally contains a plasticizer, so its physical properties are poor, that is, it cannot withstand too much pressure, and the range of use is smaller than that of the hard tube. a lot of. There is no plasticizer component in the hard tube, so the PVC hard tube is easier to mold and the pressure resistance is better than the hose.
How are PVC hoses produced? PVC hoses contain a large amount of plasticizers and some stabilizers and other ingredients. The following steps are taken during production:
The first is to prepare all the materials for the PVC hose, and determine the corresponding components according to the formula. In a certain order, the prepared materials are poured into the kneading machine at a time. The correct order is: PVC resin, plasticizer, stabilizer, lubricant, decolorizer. Under normal circumstances, only need to knead the material for 45~50 minutes, and the temperature can be taken out at 100~110 degrees Celsius.
The granulation can then be carried out. During the granulation of the PVC hose, the temperature must be controlled. The highest temperature of the material should not be lower than the melting degree of the material, and at the same time keep the temperature below the extrusion tube.
The next step is that the hose is formed. The transparency of the hose is closely related to the molding temperature. Therefore, it is the key to grasp the molding temperature. The temperature is slightly higher, and the transparency of the molded PVC hose will be higher.
The next step is traction. The speed of the traction and the speed of the cooling will affect the transparency of the hose. The speed of the traction is slightly higher, the cooling speed is faster, and the transparency of the hose is higher.
After the completion of the traction, it is curled and packaged. After the quality inspection is passed, the finished PVC hose is completed and can be put on the market.
The above content is the production process of ordinary PVC hose. Knowing how PVC hose is produced, it can also have some understanding of some of its qualities. It can be more clearly understood and differentiated when purchasing.
