Nkɛntɛnso a Sandblasting/Matt Finishing Treatment nya wɔ PTFE ntama a ɛyɛ hyew kɛse no ani nhyehyɛe so

Jiangsu Aokai New Materials, a ɛyɛ adwumayɛfo a wɔyɛ PTFE ntama a ɛyɛ hyew kɛse no de nhwehwɛmu a emu dɔ ma. Matt sanding ayaresa de nsakrae titiriw ba PTFE ntama a ɛyɛ hyew kɛse no ani nhyehyɛe mu. Ɛdannan mfitiaseɛ no ultra-inert, ultra-smooth surface no ma bondable, mmerɛw wettable functional surface fi abiɛsa: honam fam morphology, coating integrity ne surface chemical tebea.

1. Microscopic Morphology: Efi Ahwehwɛ no Anim a Ɛyɛ Torotoro Kosi Asubɔnten a Ɛyɛ Den So

PTFE ntama a ɛyɛ hyew kɛse no ani yɛ torotoro koraa wɔ microscopes ase, a polytetrafluoroethylene a wɔde melt-sintered ayɛ no sini a ɛkɔ so na ɛyɛ. Sanding ayaresa sesa ne micro-morphology kɛse:

· Nkɔanim a ɛyɛ nnam wɔ soro roughness: Mfiri a wɔde sanding (abrasive belts, steel wire brushes) anaa sand blasting (corundum, white fused alumina) twa na ɛka soro, na ɛyɛ micro-grooves, amena ne peaks a enni nhyehyɛe a enni ano. Core roughness indicators Ra (akontaabuo mu deviation of the assessed profile) ne Rz (nsɛntitiriw du sorokɔ a ɛnyɛ pɛpɛɛpɛ) dɔɔso kɛseɛ.

· Formation of mechanical anchoring structure: Saa micro-grooves yi nyɛ scratches a ɛnyɛ den, na mmom 3D interlocking structures. Eyi ne ade titiriw a ɛwɔ anchoring effect no mu: ntama a wɔde nkata so no hyɛn saa nsonsonoe yi mu na ɛsa ma ɛyɛ honam fam nkitahodi ma ɛka bom anaasɛ ɛkata so akyiri yi.

· Altered surface uniformity: Sanding a ɛfata ma wonya matte mpo awie. Adeyɛ a wɔmfa nni dwuma yiye no ma mmeae a wɔde anhwea ayɛ no boro so (ade a wɔde kata so a wɔayɛ no teateaa kɛse) ne mmeae a ɛyɛ torotoro a wɔmfa anhwea nhyɛ mu, na ɛde nsɛso a ɛsono emu biara a ɛnkɔ so pɛpɛɛpɛ ba.

2. Coating Integrity: Efi Film a Ɛnsɛe Akɔ so So Kosi Substrate a Asɛe, a Ɛda Adi So

Eyi ne asiane a ɛho hia sen biara a ɛhwehwɛ sɛ wɔhwɛ nhyehyɛe so denneennen, na ɛkyerɛ sɛnea ade no yɛ adwuma titiriw no tẽẽ:

· Thinning of PTFE layer: Sanding yɛ titiriw honam fam nneɛma a woyi fi hɔ. Mpɛn pii no, PTFE a wɔde kata ntama a ɛyɛ hyew kɛse so no mu duru fi micron du du kosi ɔhaha pii. Sanding a ɛboro so ma coating thickness so tew kɛse, ɛtew dielectric ahoɔden ne nnuru a ɛko tia corrosion service nkwa nna ase.

· Asiane a ɛwɔ fiberglass substrate a ɛda adi (dansi mu sintɔ a emu yɛ den sen biara): Sɛ grinding bun boro PTFE coating no mu duru so a, fiberglass ntama a ɛwɔ ase no bɛbɔ akɔ, na ɛde huammɔdi ahorow aba:

1. Nneɛma a ɛnyɛ nea ɛbata ho a wɔhwere: Ahwehwɛ nhama a ɛda adi no bata nneɛma ho ntɛm ara;

2. Nsu ne nnuru a ɛkɔ mu: Nsu a ɛyɛ hyew ne nnuru nam ahwehwɛ nhama a ɛyɛ ntini a ɛyɛ adwuma so hyɛn ntama no mu, na ɛma ɛyɛ delamination na ɛma adwumayɛ sɛe ntɛmntɛm;

3. Mfiri ahoɔden a ɛso tew: Ahwehwɛ nhama a ɛbɔ no ma ntama mũ no nyinaa ahoɔden a ɛtwetwe no so tew kɛse.

· Awo ntoatoaso a microcracks ne accumulated debris: Abrasive twa wɔ PTFE so ka brittle fracture ne ductile tearing bom, na ɛma microcracks ne burrs wɔ groove ano ne ase. Saa bere yi nyinaa, PTFE chips a wɔayiyi no betumi asan akɔto soro a ɛnyɛ den, na ayɛ nneɛma a ɛyɛ mmerɛw a ɛte sɛ supɔw a ɛma ahotoso a ɛwɔ ade a wɔde kata so anaasɛ ɛbɛkyekyere akyiri yi no ayɛ basaa.

3. Surface Chemical State: Efi Ultra-Inert so kosi Activated so

Ɛwom sɛ sanding yɛ nipadua mu ayaresa titiriw de, nanso ɛma nsakrae ba nnuru a ɛwɔ soro no mu:

· Ahoɔden a ɛkɔ soro wɔ soro: PTFE a ɛho tew wɔ soro ahoɔden a ɛba fam koraa (18–20 mN/m), a nsuo a ɛne ne ho di nkitaho no anim boro 108°. Bere a wɔde anhwea abɔ akyi no, nneɛma a ɛyɛ den a wɔayɛ no foforo ne molecule nkɔnsɔnkɔnsɔn a abubu no da mmeae a ahoɔden kɛse wom adi bere tiaa bi, na ɛma ahoɔden a ɛwɔ soro no kɔ soro boro 40 mN/m. Nsu nketenkete trɛw na ɛma nsu no ani yɛ nwini, na ɛda bere tiaa mu nsu a ɛyɛ dɛ adi, na bere kɔ so no, ɛyera nkakrankakra.

· Bere tiaa mu a wɔde polar dwumadi akuw ba: Ahoɔden kɛse a wɔyam no kanyan nneyɛe a ɛda PTFE molecule nkɔnsɔnkɔnsɔn a abubu ne oxygen/nsu a ɛwɔ mframa mu ntam, na ɛma polar dwumadi akuw te sɛ carbonyl (C=O) ne hydroxyl (-OH) ba ntɛm ara. Saa akuw yi ma nnuru bom ma nnuru mu nsakrae foforo anaasɛ adhesive lamination.

Nkɛntɛnso a Ɛwɔ Nkɛntɛnso Nyinaa Ho Nsɛm a Wɔaboaboa Ano

Ne tiawa mu no, sanding ayaresa a ɛfata ma micro-nano nhyehyɛe a ɛyɛ pɛ, ɛyɛ den, a ɛyɛ adwuma wɔ PTFE ntama so a ɛnsɛe fiberglass substrate a ɛwɔ ase no.

· Positive nsakrae: Yɛ mfiri interlocking texture de siesie PTFE awosu mu a enye adhesion haw.

· Mfomso bɔne: Ɔbɔ afɔre mfitiase non-stick adwumayɛ, soro smoothness ne transparency, a asiane a ɛtra hɔ daa a substrate sɛe ne ɔsom nkwa nna tiaa.

Enti, ade titiriw a ɛwɔ saa adeyɛ yi mu no da nneɛma a woyi fi hɔ no mu dɔ a wɔhwɛ so pɛpɛɛpɛ — PTFE a ɛwɔ soro no nkutoo na wɔde abraded, a ɛnka fiberglass reinforcement skeleton no. Wɔtaa de ntama a wɔayɛ no yiye no kɔ nneɛma a wɔde kata so anaasɛ wɔde kyekyere nneɛma so ntɛm ara na ama wɔanya ne soro tebea a eye sen biara a wɔayɛ no adwuma no so mfaso koraa.
