Manufacturing process of silicone tube

Since the formation of silicone tube is a modern product, it is very late compared to plastic. The long-term way of appearance of silicone tube is mainly in water pipe. Because the safety performance of silicone is better than other materials, the purpose of it is also simple to drain drinking water. Realizing that there will be a grade distinction, it is for the purpose of being a substitute for other pipes. With the continuous expansion of the field of use and good feedback, the market gradually forms.

Silicone tube is the circulation and coating carrier of liquid, gas and other materials. It is widely used in daily necessities and modern industry. The raw silicone rubber is added to a double-roll rubber mixing machine or a closed kneader, and white carbon black and other additives are gradually added to make the product uniformly. According to the technical standards of the industry, the product is made by extrusion.

The silicone tube is extruded at the front end and spraying equipment can be installed at the back end to achieve the method of extruding while spraying oil. Nowadays, manufacturers with more silicone tube production capacity choose to increase the production capacity. The main princIPLe is that the silicone tube increases the mold at the front end to form a circle. The shape of the tube is vulcanized in a high-temperature oven to make the silicone tube preliminarily formed, and the silicone tube in this link is not sprayed with oil, so the silicone tube enters the drying tunnel about 10 meters long for vulcanization and molding until the end is shipped. Extrusion has been completed so far, and the oil-sprayed silicone tube enters the spray drying tunnel again for a layer of spray treatment.

The silicone tube uses imported raw materials as the main component and chemical factors are stable. Adjust to 600N/min according to the rotation of the peristaltic pump, and then put the two ends of the tube in some neutral acid-base liquids to actually test the life time. It cannot be broken or leaked for more than 14 days. In addition, all other silicone hose products will not reach the peristaltic pump silicone tube, and the life span is unimaginable even in a corrosive acid-base environment.

The longer the raw material of the silicone tube is exposed outdoors, it means the greater the tolerance of the hardness of the finished product will be. The hardness tolerance of the food-grade silicone tube is generally controlled at about ±3 degrees under the constant temperature and clean environment of the dust-free workshop. The positive and negative tolerances of the food-grade silicone tube produced in the dust-free workshop are between ±5-7°, which proves that the hardness stability of the silicone tube produced in the dust-free workshop is greater than that of the ordinary environment.
