As we all know, teflon (PTFE) is called "plastic king". Due to its excellent analytical chemistry credibility and corrosion resistance, PTFE products have played an important role in pharmaceutical factories, industrial equipment, electronic components, electrical products, military applications, ecological environment protection, roads, roads and bridges. Among them, Teflon plate It is more widely used. PTFE board (also called Teflon plate) can be divided downward into Molded plate And cutting plate. So, do you know the difference between PTFE cutting plate and PTFE molding plate? What is the production process of Teflon plate?
Tetrafluoroethylene cutting plate and PTFE board One of the obvious differences between them is that their processing technology is different. Polytetrafluoroethylene cutting plate is made of polytetrafluoroethylene epoxy resin rubber and plastic insulation plate, which is burned and then turned into a commodity, while the polytetrafluoroethylene rubber and plastic insulation plate is formed at room temperature, and then burned and cooled. In addition to the difference in processing technology, there is a difference between the tetrafluoro cutting plate and the tetrafluoro molding plate in the middle, that is, their thickness is different, that is, the thickness of the tetrafluoro cutting plate is 0.5mm-8mm, while the thickness of the tetrafluoro rubber insulation plate is 5mm-50mm.
In fact, no matter what kind of production and manufacturing expertise, the production process of bismuth tetroxide board is not much worse.
1. The raw materials are well prepared: F4 epoxy resin adhesive; Alcohol; Mold; Sintering furnace
2. Fully prepare the mold: before pouring F4 epoxy resin adhesive into the mold, clean it with alcohol to ensure that there are no rusty scratches or attachments inside and outside the mold. Such practices can ensure that Teflon plate It is not easy to have all difficulties due to its cleanliness level and detail.
3. Weighing: calculate the net weight according to the formula G=PV (where G is the amount of pellet feed, P is the product density (2.18g/cm3), and V is the product capacity).
4. Feeding: Pour F4 epoxy resin glue evenly into all pressing surfaces, which will ensure Teflon plate The flatness and color distance are not too large, otherwise, the color and thickness of the Teflon plate will be different.
5. Pre forming (inhibition): calculate the pressure of the pressure gauge according to the calculation formula, then set the inhibition pressure and inhibit the epoxy resin adhesive.
6. Demoulding and finishing: remove the production processing from the mold and conduct surface finishing to make the surface smooth, the edges neat and formable.
7. Forging: slowly put the production and processing into the sintering furnace, moderately put it into the sintering furnace, heat up about 1 hour to 390 degrees, heat preservation and insulation for about an hour, and then start to cool down after about 4 hours until the indoor temperature is guaranteed, and then carry out the product output from outside the furnace, and then carry out the installation.
The teflon plate produced by the product is durable, reliable in airtightness, soft and easy to cut by optical fiber laser, can be clamped by industrial equipment or hand pull, and easy to install. Therefore, it is widely used in industrial production of high and low temperature, corrosion-resistant raw materials, cable sheath raw materials, degumming industrial coatings and other industries.
