Pvc pipes are very common in our daily life, and because of the economical benefits, general home decoration can use it. Pvc pipe is mainly divided into hose and hard pipe. 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 is the pvc hose produced? The hose contains a lot of plasticizers and some stabilizers and other ingredients. It takes a few steps to produce.
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 molding. 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 contents are the pvc hose production process shared today. To understand how PVC hoses are produced, we can have some understanding of some of its qualities, and we can understand and distinguish the advantages and disadvantages more clearly when purchasing.
