Ɔfã 2: PTFE Impregnation Emulsion a wɔyɛ

Wɔkyerɛ ntama a etwa to no honam fam ne nnuru a ɛwɔ mu no kɛse wɔ saa bere yi mu.

Ɔfã 3: Core Impregnation ne Sintering

Eyi ne adeyɛ titiriw a ɛma PTFE ntama no yɛ adwuma soronko, a mpɛn pii no ɛfa kyinhyia a wɔtaa yɛ ho.

Multiple Impregnations Wɔ nhyɛso a wɔde di dwuma daa ase no, ntama a wɔde gyina so a wɔadi kan ayɛ ho adwuma no fa dip tank a PTFE emulsion ahyɛ mu ma mu mpɛn pii. Sɛnea ɛbɛyɛ na wɔanya ne kɛse ne density a wɔpɛ no, ade a wɔyɛ no fa ɔkwan a ɛyɛ kyinhyia so: impregnation → drying → sintering . Kyinhyia biara ma ade a wɔde kata so no mu duru kɔ soro pɛpɛɛpɛ.
