Cross-sectional Structure of PTFE High-Temperature Cloth: So Nsakrae Bi Wɔ PTFE Coating ne Fiberglass Substrate Ntam?

Jiangsu Aokai New Materials, a ɛyɛ adwumayɛfo a wɔyɛ PTFE ntama a ɛyɛ hyew kɛse no de nhumu a emu dɔ brɛ wo. Sɛ́ ade a wɔabom ayɛ a ɛyɛ adwuma yiye no, microscopic cross-sectional nhyehyɛe a PTFE ntama a ɛyɛ hyew kɛse no ho hia kɛse ma ne hyew a ɛko tia, ne peel ahoɔden ne flexibility. Wɔ PTFE ntama a ɛyɛ hyew kɛse a wɔyɛ mu no, ampa .  nsakrae a ɛho hia wɔ PTFE a wɔde kata so ne fiberglass substrate no ntam Sɛ saa nsakraeɛ layer yi nni hɔ a, wɔrentumi nnya PTFE ntama a ɛyɛ hyew a ɛkorɔn no structure integrity a wɔaka abom.

Ɛnam cross-sectional microscopic analysis so no, saa nsakraeɛ layer yi nyɛ nnuru baako, na mmom ɛyɛ interfacial zone a wɔabom ayɛ a ɛnam honam fam ne nnuru mu nsakraeɛ akwan ahodoɔ so na ɛyɛeɛ. Wɔakyerɛkyerɛ ɔkwan a wɔfa so hyehyɛ ne sɛnea wɔyɛ nsakrae no mu kɔ akyiri sɛnea edidi so yi:

1. Silane Nkitahodi Agent Bonding Layer

Fiberglass a wɔansiesie no ntumi ne PTFE resin nkɔ tẽẽ. Enti, ɛsɛ sɛ wɔde silane coupling agents sesa fiberglass ntama wɔ ne yɛ mu. Ade a ɛka bom no ano biako ne silanol akuw (Si-OH) a ɛwɔ fiberglass no ani no yɛ adwuma wɔ nnuru mu, bere a awiei foforo no kura akuw a ɛyɛ nnam a ɛne fluororesins wɔ abusuabɔ kɛse anaasɛ ɛyɛ adwuma. Ɛsom sɛ nnuru bonding bridge a ɛda fiberglass nnompe ne PTFE coating ntam, saa layer yi ma titiriw nnuru anchorage ma ne nyinaa structural lamination.

2. Hot-Melt Adhesive Mfinimfini Fam

Wɔ cross-section hwɛ a ɛkorɔn PTFE ntama a ɛyɛ hyew kɛse mu no, wobetumi ahu gradient transition layer a PFA (Perfluoroalkoxy alkane) anaa FEP (Fluorinated Ethylene Propylene) wom pefee wɔ PTFE coating ne fiberglass substrate ntam. Wɔ ɔhyew a ɛkɔ soro sintering mu no, saa fluoroplastics a ɛtumi nwene yi yɛ adwuma sɛ ntama a ɛyɛ hyew a ɛyɛ hyew wɔ mu, na ɛhyɛn fiberglass bundles mu na ɛkyekyere ma ɛyɛ ɔfa a ɛkɔ so. Saa mfinimfini fã yi siw coating delamination ano yiye wɔ bending ne flexing tebea horow a ɛtaa ba mu.

3. Mfiri a Wɔde Di Dwuma Nkitahodi

Wɔnam akwan pii a wɔfa so de nsu gu mu ne nea wɔde kata so so na ɛyɛ PTFE ntama a ɛyɛ hyew kɛse. Sɛ yɛde afiri ketewaa bi hwɛ a, PTFE emulsion hyɛn ntini a ne kɛse te sɛ micron a fiberglass ntama a wɔpam no warp ne weft na ɛyɛ no mu. Afei sintering na curing, solidified PTFE resin yɛ afã abiɛsa mfiri anchoring nhyehyɛe ne fiber ntama.
