Wetin Mek PTFE Fabrik Nɔ Gɛt Po Fleks Resistɛns?

Di rut kɔz na di fayv glas sabstret , nɔto di PTFE kɔtin.

1. Fayba glas – strɔng bɔt i brit

di glas fayb dεm gεt ekstrim hכy tεnsil strכng bכt rili lכw εlongeshכn we dεn de brok (tipikli 2-4%). We dɛn bɛn am bɔku bɔku tɛm, wan wan filamɛnt dɛn kin taya ɛn brok. wans fכ fayv dεm brok, strεs de kכnsantre pan di rεst wan dεm, we de mek dεn prכpagεshכn kwik kwik wan – di fכs de te izi wan.

Ki takeaway: PTFE-coated fiberglass sidon na di mid-to-lɔwa ɛnd bitwin ay-tɛmpracha fabrik fɔ fleks rɛsistɛns. I bɛtɛ pas bare glas bɔt i wɔs fa fawe pas pure PTFE film.

Ki Factors We Afɛkt Fleks Resistans

1. Tiknɛs – di tin we rili impɔtant

Rul of thumb: Fabrik dɛn we tinap kin fleks bɛtɛ. Fɔ aplikeshɔn dɛn we nid fɔ bɛnd ripit, spɛsifa di gred we tan pas ɔl we mit yu ɔda nid dɛn (strɛng, tɛmpracha).

2. Wev kɔnstrɔkshɔn

• Satin wev – lכng flot dεm de alaw di yarn dεm fכ slayv sכmtεm, we de sheb bεnd strεs. Bɛtɛ fleks layf pas plain wef.

• Plɛn wev – tayt intalaysin pɔynt dɛn lɔk yan; strεs de kכnsantreyt na intasekshכn dεm. Wos fleks rɛsistɛns.

3. Tεmprachכ we dεn de wok

We di tɛmpracha de ɔp (200-260°C), di PTFE kɔtin kin sof, ɛn di fayv glas mɛkanikal trɛnk kin go dɔŋ. Dis de mek di fleks taya resistans wɔs mɔ. If yu aplikeshɔn gɛt fɔ du wit ɔl tu di ay ɔt ɛn fɔ bɛn am ɔltɛm, ɛkspɛkt fɔ gɛt shɔt layf.

4. Bɛnd rayus

Big rayus = lɔng layf. shap kris (rayus <1mm) de mek dεd fold dεm wit instantaneous fayb brεk. Fɔ gayd rɔla, yuz di big prɛktikal dayamita. As rough guide, di minimum rekomend rola dayamita na 10-20x di fabrik tiknes.

Intanɛt tɛst data (Aokai PTFE) : Fɔ 0.13mm satin wev fabrik, fɔ bɛnd oba 10mm mandrel ajɔst 500-800 saykl bifo visible krak krak. Ova wan 5mm mandrel, saykl dεm dכn dכn to 100-150. ova wan 2mm mandrel (shap kris), fεil de apin insay 20 saykl dεm.

Praktikal Aplikeshɔn Rikɔmɛndishɔn dɛn

If yu ikwipmɛnt nid fɔ bɛnd bak ɔltɛm – lɛk:

• High-frikyuɛnsi wɛlda drayv bɛlt dɛn

• Tɛnshɔn bɛlt dɛn we de rap rawnd smɔl smɔl pul dɛn

• Demolding conveyor belts wit shap tɔn

Yu gɛt tri tin dɛn we yu go ebul fɔ du:

1. Opshɔn 1 – Optimayz PTFE fabrik sɛlɛkshɔn insay in limit

• Pik di gred dɛn we tinap (0.08mm to 0.13mm) pas di wan dɛn we ebi

• Prɛfer satin wev pas plain wev

• Rikwest MIT fleks tɛst data frɔm yu spɔlayt (ASTM D2176 ɔ ɔda tin we tan lɛk am)

• Disain fɔ big bɛnd rayus na di mashin layout

• Aksept PTFE fabrik as konsumabl – plan fɔ riples am wan wan tɛm (ɛvri sɔm mɔnt dipen pan saykl kɔnt)

2. Opshɔn 2 – Swich to sɔlid PTFE fim

Pure PTFE film (skived) gɛt ɛksepshɔnal fleks rɛsistɛns. Bɔt i nɔ gɛt di fayv glas riinfɔsmɛnt, so i gɛt smɔl tɛnsiɛl trɛnk ɛn i izi fɔ te we i tɛnsi. I fayn fɔ layt-duti, lɔw-tɛnshɔn bɛnd aplikeshɔn dɛn.

3. Opshɔn 3 – Yuz aramid ɔ ɔda ɔrganik fayba klos

Aramid (ɛgz., Nomex) ɔ PPS fabrik we dɛn kɔt wit PTFE de gi bɛtɛ fleks layf pas glas-based PTFE fabrik. Di trade-off: lכw kכntinyu tεmprachכ rεsistεns (tipikli ≤200°C) εn difrεn sכfayz prכpati dεm. Fɔ aplikeshɔn ɔnda 200°C wit ebi bɛnd, tink bɔt dɛn ɔda we ya.
