Calendering Nsunsuansoɔ a ɛwɔ PTFE Nneɛma so: Nsakraeɛ titire 5 a ɛba wɔ adwumayɛ mu

So woasusuw nea enti a ebinom ho pɛn PTFE ntama a ɛyɛ hyew kɛse wɔ ahwehwɛ-te sɛ awie bere a afoforo hwɛ matte anaasɛ textured? Mmuae no ne calendering – post-sintering adeyɛ a ahwehwɛ rollers a ɛyɛ hyew de linear nhyɛso a ɛkorɔn di dwuma de san yɛ ade no ani.

Calendering sesa microstructure, surface condition, ne service performance a ɛwɔ PTFE ntama a ɛyɛ hyew kɛse mu titiriw .
