PVDF Narrow Cheese Head Slotted Screws

PVDF Narrow Cheese Head Slotted Screws applications are mainly concentrated in three major fields: petrochemical, electrical and electronic, and fluorocarbon coatings. It is widely used in chemical anti-corrosion, electrical and electronic, semiconductor, water treatment, food, pharmaceutical and bio-engineering, automobile manufacturing, construction, and other industries.

The plastic screws on the cover plate of the energy storage battery are used to fix the power supply circuit board because the power supply itself is through the interface inserted in the motherboard to transmit power to other hardware if the power supply circuit board is loose or fall off, it will lead to unstable power supply, and the plastic screws, which are designed to prevent the power supply circuit board from receiving vibration and loosening or falling off, and at the same time, it can also play a role in insulating and shielding the role of electromagnetic interference. Therefore, the plastic screws in the energy storage battery are also very important.

In the new energy lithium batteries and energy storage battery industry, will choose plastic screws as commonly used fasteners. In addition to plastic screws there is an essential feature is better acid and alkali resistance, especially in PVDF Narrow Cheese Head Slotted Screw this screw acid and alkali resistance has great advantage nylon screws compared to PVDF Narrow Cheese Head Slotted Screw acid and alkali resistance will be a little worse. Still, the strength will be higher, so to cope with different conditions of use and the environment need to pick different materials of plastic screws to ensure cost-effectiveness and practicality.

In many of these plating or this kind of strong acid and alkali environment, screws: PVDF screws, PEEK screws, PVC screws, nylon 66 screws, PPS screws, PTFE screws, PC screws, and PP screws are widely used.

For energy storage batteries for lithium batteries, the temperature, sealing, and republican safety of the protection requirements are incredibly high, and insulated plastic screws in the assembly process have a pivotal role.

1. Anti-leakage, that is, overcurrent problems, energy storage batteries in the finished product assembly will pass the current test. These overcurrent parts are usually terminals. Poor contact will occur at the terminal connection when the terminals are not locked, resulting in significant resistance and local overload heating. It is possible to burn the terminals, so use the plastic screws with excellent tightness to tighten to avoid a false fit situation.

2. sealing, plastic screws, and rivets not only play a role in tightening the connection and in sealing and also has a vital role in the design of plastic screws to increase the sealing teeth, sealant, and insulation gasket sealing elements.
