Polytetrafluoroethylene tubing forming method and sintering process and diameter determinant

- Apr 18, 2019-

Polytetrafluoroethylene tubing, a kind of tubing made of PTFE, is a specific type of tubing and is widely used in some industries and fields. Therefore, in order to correctly and reasonably use this type of pipe, the following will familiarize and understand through the learning and mastery of related knowledge, so as to achieve the above objectives.

1. How to choose the quality of polytetrafluoroethylene tubing?

Polytetrafluoroethylene tubing needs to be selected for good quality. It is necessary to do the following two points: First, have a clear understanding of the demand for use, and determine the price range of the product that you can afford, so as to further narrow the scope of choice. Second, we must choose professional and regular manufacturers, so as to ensure product quality and product performance, and thus ensure good product use.

2. Forming method and sintering process of polytetrafluoroethylene tubing

There are more than a dozen molding methods for the forming method of polytetrafluoroethylene tubing, specifically for molding, pushing, skin, spraying, weaving, winding, rolling, and extrusion. , bonding method, welding method, heat setting method and machining method, which one is selected is determined by processing requirements and product use.

The sintering process of polytetrafluoroethylene tubing can be said to be an important aspect. It should not be underestimated and sloppy, and it has corresponding parameters for sintering temperature, holding time, heating rate, molding temperature, molding shrinkage and sintering. condition. Moreover, you need to know that the sintering temperature is 380 ° C, the holding time is 4 hours, the heating rate is 200 ° C below 80 ° C / h, 200 ° C above 60 ° C / h, the molding temperature is 330 ° C - 380 ° C, the molding shrinkage is 3% - 5%. In addition, the sintering conditions are such that the temperature cannot exceed 385 ° C, otherwise the sintering quality will be affected.

3. What is the diameter of the polytetrafluoroethylene tubing? Is there a difference between transparency and white?

The pipe diameter of polytetrafluoroethylene tubing is professionally related to the specific use and service requirements of the pipe, and has a great relationship with the specific use of the pipe. Sometimes the specific diameter of the pipe can be determined according to this point. The transparent and white Teflon tubing is different. First, it is different in color, and secondly, it is different in material composition.www.yihaoptfe.com
