PTFE Raw Material Purity – Efĩ bɛn na ɛwɔ hɔ?

Efĩ a ɛtaa ba wɔ PTFE mu no bi ne:

• Monomers a ɛnyɛ adwuma ne polymers a emu duru sua

• Nneɛma a wɔde fi ase ne nea wɔde petepete nkae (sɛ nhwɛso no, PFOA) .

• Dade ions (dade, kɔbere, sodium) .

• Mmoa a wɔde yɛ adwuma ne nneɛma a efi mu ba

Ahotew a ɛkorɔn ma ade no tumi de adwumayɛ a ɛbɛn nsɛm a ɛfata ma.

1. Ɔhyew a ɛko tia ne ɔhyew a ɛgyina pintinn

Dade ions (dade, kɔbere, sodium) yɛ adwuma sɛ nneɛma a emu yɛ den a ɛma PTFE hyew sɛe . Wɔ bere tenten som a ɛboro 260°C ase no, dade nketenkete mpo ma molecule nkɔnsɔnkɔnsɔn no bubu ntɛmntɛm, na ɛma ɛyɛ mmerɛw ntɛm na ɛpaapae. PTFE a ɛho tew kɛse no da ɔhyew a ɛporɔw ɔhyew a ɛkorɔn adi, ɛkɔ so yɛ fitaa a ɛho tew, na ɛko tia kɔkɔɔ yiye.

2. Non-stick adwumayɛ ne soro su

Polymers a emu duru sua ne nneɛma a efi mu ba a ngo wom no tu kɔ nea wɔde kata so no ani bere a wɔde ɔhyew kɛse reyɛ sintering no, na ɛyɛ nsu a ɛtɔ.

• Nneɛma a ɛnyɛ nea ɛbata ho a asɛe: Ne soro bɛyɛ tacky na ɛtaa bata nneɛma a wɔayɛ ho adwuma (aduan, ntama a wɔde nkata so).

Fiberglass Substrate Ahotew – Alkali a Ɛwɔ Mu Ho Nsɛm

Fiberglass nyɛ silicon dioxide a ɛho tew. Nnuru a ɛwɔ mu no kyerɛkyerɛ ɔhyew a ɛko tia, mfiri ahoɔden, ne nkitahodi a ɛne PTFE bɔ mu.

1. Alkali metal oxide a ɛwɔ mu – ade a ɛyɛ gyinaesi

Wɔ ɔhyew a ɛkɔ soro mu no, ɛnyɛ sɛ alkali dade ions a efi ahwehwɛ a ɛho tew pii mu no ma ntama no ankasa yɛ mmerɛw nko na mmom ɛma PTFE a wɔde kata so no sɛe , na ɛma huammɔdi nyinaa yɛ ntɛmntɛm. Bio nso, ahwehwɛ a ɛwɔ medium/high-alkali twetwe nsu, na ɛma insulation a ɛko tia no so tew kɛse.

2. Sizing agents – efĩ foforo no
