We should have seen "plumber tape" in our daily lives. Generally, when installing pipes in a house, the pipe installer must write the words "water tape" on the purchase order. Next, follow us to get to know this common but extraordinary utility.
What is plumber tape
Plumber tape, also known as water tape, raw tape, scientific name polytetrafluoroethylene tape, polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE. Common white PTFE tapes are commonly used in HVAC and water supply and drainage, and there are special PTFE tapes for natural gas pipelines. In fact, the main raw materials are all PTFE, but some processes are different.
The plumber tape is produced with imported materials and advanced technology, with high quality and complete specifications, which can meet the requirements of different customers in different industries. PTFE tape is the residual deformation of the resin under the action of pressure. It is first made into rods or strips by pressing and forming, and then placed on a roller press. Under the action of the roller pressure, it stretches into a thin strip with a certain thickness and width, and finally removes the squeezing aid to obtain a raw material strip.
Application of plumber tape
Polytetrafluoroethylene can be formed by compression or extrusion processing; it can also be made into water dispersion for coating, impregnation or making fibers. PTFE is widely used as high and low temperature resistant, corrosion resistant materials, insulating materials, anti-stick coatings, etc. in nuclear energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, food and other industries.
Polytetrafluoroethylene is widely used in all kinds of acid and alkali resistance and organic solvents. It is not toxic to humans. However, one of the raw materials used in the production process, perfluorooctanoate (PFOA), is considered to have carcinogenic effects.
The expanded polytetrafluoroethylene raw material tape uses 100% polytetrafluoroethylene as the raw material, and it has a net-like expanded structure composed of fine long fibers and knots. The expanded polytetrafluoroethylene raw material tape has the characteristics of good toughness, high longitudinal strength, and easy deformation in the transverse direction. It is an ideal material for sealing on discs and threads. However, it cannot be used in situations where it is in contact with high-concentration oxygen or liquid oxygen.
How to use plumber tape
1. The plumber tape needs to be wound along the thread direction, which greatly reduces the sealing performance;
2. Do not wrap all threads with tape, otherwise the ptfe tape will enter the pipe and reduce the sealing performance. We need to start winding from the second thread at the beginning of the thread, leaving the first thread;
3. When winding the plumber tape, it is necessary to use a little force to ensure that the tape is wound without being broken. The tape wound in this way is tight and firm enough to ensure the tightness;
4. After the tape is wound, do not unwind the threaded pipe once it is tightened, otherwise it needs to be re-wound and tightened;
