Nug

PTFE muaj npe nrov rau nws cov coefficient tsis tshua muaj kev sib txhuam (0.05-0.10). Tab sis thaum twg PTFE high-temperature daim kab xev yog siv nyob rau hauv zawv zawg kev sib txhuam daim ntaub ntawv - xws li kev taw qhia rails, hnav strips, chute liners, los yog zawv zawg seals - kev sib txhuam ib leeg tsis txaus. Qhov kev sib tw tiag tiag yog kev puas tsuaj.

Yog tias tsis muaj kev xaiv zoo, PTFE txheej hnav dhau lub lis piam, nthuav tawm cov fiberglass substrate thiab ua rau muaj kev puas tsuaj loj. Standard non-stick daim kab xev tsis yog tsim rau dynamic zawv zawg sib cuag.

Aokai PTFE tau tsim PTFE daim kab xev rau kev thov zawv zawg daim ntaub ntawv. Cov lus qhia no suav nrog tsib qhov kev txiav txim siab tseem ceeb: kev ntsuas kev puas tsuaj, txheej txheej zoo, thermal stability, kev ua haujlwm nplaum, thiab cov txheej txheem kev teeb tsa.

Core Performance Indicators los txheeb xyuas

1. Abrasion Resistance – Qhov tseem ceeb Parameter

Txoj Kev Xeem	Txuj	Tus nqi (Standard PTFE)	Target rau Hnav-Resistant Daim kab xev
Taber Abrasion Loss (ASTM D4060, CS-17 log, 1000g load)	mg/1000 cycles	Pua pua mg	<15 mg (hwm: <5 mg)
Dynamic Coefficient ntawm kev sib txhuam	μ	0.05-0.10 Nws	Ruaj khov 0.05-0.15 dhau lub neej
PV Limit (siab × ceev)	Pa·m/s or psi·fpm	Nws txawv ntawm formulation	Tau txais los ntawm tus neeg muag khoom

Vim li cas Taber abrasion tseem ceeb: Ntshiab PTFE txheej hnav sai sai hauv kev sib cuag. Hloov kho PTFE (nrog carbon fiber, graphite, MoS₂, lossis iav fiber ntau) txo qis hnav. Hwm hnav-tiv taus daim kab xev tuaj yeem ua tiav <5 mg poob ib 1000 cycles - 20-50x zoo dua PTFE unfilled.

PV txwv tau txhais: Qhov siab tshaj plaws pub khoom ntawm kev sib cuag Siab (P) thiab zawv zawg Velocity (V). Tshaj qhov kev txwv no ua rau hnav sai, overheating, los yog txheej tsis ua hauj lwm. Ib txwm thov PV nkhaus los ntawm koj tus neeg muag khoom.

Aokai PTFE muab cov qhab-nees hnav-tiv taus nrog Taber abrasion poob qis dua 10 mg / 1000 cycles - validated los ntawm ywj siab ASTM D4060 kuaj. Peb cov txheej txheem carbon-fiber-filled tswj μ hauv qab 0.15 txawm tias tom qab 10,000 cycles.

2. Txheej zoo & kev tsim kho substrate

Parameter	Kev pom zoo	Vim li cas
Txheej thickness (ua hauj lwm nto)	≥0.05mm (0.08-0.15mm rau hnyav hnav)	Thicker txheej muab lub neej ntev dua
Txheej hom	Filled hloov kho PTFE (carbon, graphite, MoS₂, iav fiber)	Far superior abrasion kuj vs. unfilled
Txheej kev ncaj ncees	Tsis muaj pinholes, tag nrho sintered	Tiv thaiv kom tsis pub dhau ntxov ntawm fiberglass
Base ntaub tensile zog	≥200 N / cm	Resistant stretching nyob rau hauv shear kev sib txhuam
Weave hom	High-strength dawb los yog satin weave	Aramid ntaub rau hnyav loads

3. Thaum tshav kub kub Resistance & Thermal Stability

Kev pabcuam kub tsis tu ncua yuav tsum ua raws li qhov yuav tsum tau ua haujlwm (feem ntau ≥260 ° C)
Tsis muaj drastic txheej softening los yog ceev abrasion thaum tshav kub kub
Tom qab thermal aging ntawm 250 ° C rau 100 teev, tensile lub zog thiab puas degradation yuav tsum tsis pub tshaj 20%

4. Adhesive Layer Performance (Rau Self-Adhesive Tapes)

Hom nplaum	Kub Resistance	Anti-Creep	Haum rau zawv zawg
Silicone PSA	≤ 260 ° C	Zoo nrog kev sib txuas kom raug	Mainstream xaiv
Acrylic PSA	≤150 ° C	Tsis zoo nyob rau hauv tshav kub	Tsis pom zoo rau high-temperature zawv zawg
Primer + silicone	≤ 260 ° C	Zoo heev	Rau qis-nto-zog substrates (piv txwv li, stainless hlau)

Lus Cim: Rau qhov hnyav-load zawv zawg daim ntaub ntawv qhov twg daim kab xev yog nyob rau hauv tas li shear stress, xav txog txhua yam fastening (rivets, clamping strips) ntxiv rau cov nplaum.

5. Nto Texture & Thickness Uniformity

Deg kev ntxhib los mos: me ntsis embossed kev ntxhib los mos pab khaws cov khib nyiab zoo, tiv thaiv coefficient spikes lossis plough-type abrasive hnav los ntawm cov khoom sib xyaw.
Thickness kam rau ua: Tag nrho cov thickness tswj nyob rau hauv ± 0.02 hli thoob tag nrho yob kom huv si installation thiab tsis txhob localized ntxov ntxov puas.
