PTFE High-Temperature Npuag: Vim Li Cas Nws Folds Tsis Zoo thiab Koj Yuav Ua Li Cas

Yog koj puas tau folded ib daim PTFE-coated fiberglass npuag sharply, tej zaum koj yuav pom ib tug dawb crease kab tshwm instantly. Quav nws dua nyob rau tib qhov chaw, thiab cov ntaub yuav tsim kua muag.

Qhov no tsis yog qhov tsis xws luag - nws yog tus cwj pwm ntawm cov khoom siv. PTFE high-temperature fabrics excels at resisting heat, chemicals, and sticking, but flex resistance (rov folding endurance) yog nws cov khoom tsis muaj zog tshaj plaws.

Aokai PTFE tau sim flex lub neej hla ntau thicknesses thiab weaves. Kab lus no piav qhia vim li cas cov ntaub folds tsis zoo, muab piv rau lwm cov ntaub ntawv, thiab muab txoj hauv kev los ua haujlwm nyob ib ncig ntawm qhov kev txwv.

Vim li cas PTFE Fabric Muaj Flex Resistance tsis zoo?

Lub hauv paus ua rau yog fiberglass substrate , tsis yog PTFE txheej.

1. Fiberglass - muaj zog tab sis nkig

Cov iav fibers muaj lub zog tensile siab heev tab sis tsis tshua muaj elongation thaum tawg (feem ntau 2-4%). Thaum khoov dua, ib tus neeg filaments raug qaug zog thiab tawg. Ib zaug ob peb fibers tawg, kev ntxhov siab concentrates rau ntawm qhov seem, ua rau kev nthuav tawm sai - cov ntaub kua muag tau yooj yim.

2. PTFE txheej – ib tug txwv tsis pub

PTFE txheej lubricates cov fiber ntau, txo cov kev sib txhuam sab hauv thiab me ntsis kev txhim kho pliability. Txawm li cas los xij, nws tsis tuaj yeem tshem tawm qhov brittleness ntawm iav. Nws tsuas yog ncua fiber ntau rupture los ntawm ib tug me me paj.

Nws Puas Sib Piv rau Lwm Cov Khoom Siv?

Cov khoom tseem ceeb: PTFE-coated fiberglass zaum ntawm nruab nrab mus rau qis kawg ntawm cov ntaub kub kub rau flex kuj. Nws yog qhov zoo dua li iav liab tab sis deb dua li cov yeeb yaj kiab PTFE ntshiab.

Yam tseem ceeb uas cuam tshuam rau Flex Resistance

1. Thickness - qhov tseem ceeb tshaj plaws

Txoj cai ntawm tus ntiv tes xoo: thinner fabrics flex zoo dua. Rau cov ntawv thov uas yuav tsum tau rov kho dua, qhia cov qib thinnest uas ua tau raws li koj qhov kev xav tau (lub zog, qhov kub thiab txias).

2. Weave kev tsim kho

• Satin weave - ntev floats tso cai rau yarns swb me ntsis, faib kev ntxhov siab khoov. Lub neej zoo dua qub dua li cov weave.

• Plain weave - nruj interlacing ntsiab lus xauv yarns; kev ntxhov siab concentrates ntawm kev sib tshuam. Phem flex kuj.

3. Ua haujlwm kub

Ntawm qhov kub siab (200-260 ° C), PTFE txheej softens, thiab fiberglass mechanical zog poob. Qhov no ntxiv ua rau flex fatigue tsis kam. Yog tias koj daim ntawv thov muaj ob qho tib si kub kub thiab nquag khoov, cia siab tias lub neej luv dua.

4. Khoov vojvoog

Lub vojvoog loj dua = lub neej ntev. Nthuav creasing (lub vojvoog <1mm) tsim cov folds tuag nrog instantaneous fiber breakage. Rau kev taw qhia rollers, siv qhov loj tshaj plaws txoj kab uas hla. Raws li cov lus qhia ntxhib, qhov tsawg kawg nkaus pom zoo rau cov menyuam txoj kab uas hla yog 10-20x cov ntaub tuab.

Cov ntaub ntawv kuaj sab hauv (Aokai PTFE) : Rau 0.13mm satin weave npuag, khoov tshaj 10mm mandrel tiav 500-800 cycles ua ntej pom kev tawg. Tshaj 5 hli mandrel, cycles poob rau 100-150. Tshaj 2 hli mandrel (ntse crease), tsis ua hauj lwm tshwm sim nyob rau hauv 20 cycles.

Cov tswv yim siv tswv yim

Yog tias koj cov cuab yeej xav tau ntau zaus reciprocating dabtsi yog khoov - xws li:

• High-frequency welder tsav siv

• Cov hlua khi uas qhwv ib ncig me me rubleys

• Demolding conveyor siv nrog ntse tig

Koj muaj peb txoj kev xaiv:

1. Kev xaiv 1 - Txhim kho PTFE npuag xaiv nyob rau hauv nws cov kev txwv

• Xaiv cov qib thinner (0.08mm txog 0.13mm) tshaj qhov hnyav

• Nyiam satin weave tshaj qhov yooj yim weave

• Thov MIT flex cov ntaub ntawv xeem los ntawm koj tus neeg xa khoom (ASTM D2176 lossis zoo sib xws)

• Tsim kom loj bending radii nyob rau hauv lub tshuab layout

• Txais PTFE npuag raws li cov khoom siv tau - npaj rau lub sijhawm hloov pauv (txhua ob peb lub hlis nyob ntawm lub voj voog suav)

2. Kev xaiv 2 – Hloov mus rau cov khoom PTFE zaj duab xis

Ntshiab PTFE zaj duab xis (skived) muaj qhov tshwj xeeb flex kuj. Txawm li cas los xij, nws tsis muaj fiberglass reinforcement, yog li nws muaj zog tensile qis thiab kua muag yooj yim dua nyob rau hauv nro. Nws yog haum rau lub teeb-lub luag hauj lwm, low-tension dabtsi yog khoov daim ntaub ntawv.

3. Kev xaiv 3 - Siv aramid los yog lwm yam organic fiber ntaub

Aramid (piv txwv li, Nomex) los yog PPS ntaub coated nrog PTFE muaj zoo flex lub neej tshaj iav-raws li PTFE ntaub. Kev lag luam tawm: qis dua qhov kub tsis tu ncua (feem ntau ≤200 ° C) thiab cov khoom sib txawv. Rau cov ntawv thov hauv qab 200 ° C nrog hnyav dabtsi yog khoov, xav txog cov kev xaiv no.

Aokai PTFE tsim PTFE-coated aramid ntaub ntawm kev thov. Tiv tauj peb rau cov ntaub ntawv kub thiab flex.

Summary - Paub qhov txwv, tsim raws li

PTFE high-temperature npuag sawv zoo tiv thaiv nruj, kub kub (260 ° C), thiab tshuaj tua kab mob. Tab sis nws tsis zoo flex kuj yog ib qho kev txwv tiag. Nws tsis tuaj yeem tiv taus ntse dua folding zoo li roj hmab siv los yog ntshiab PTFE zaj duab xis.

Siv nws qhov twg khoov maj mam los yog tsis tshua muaj.
Qhov twg ntse los yog nquag khoov tsis tuaj yeem zam tau, mus nyias, siv satin weave, nce bending vojvoog, lossis hloov khoom siv.

Aokai PTFE muab cov ntaub ntawv xeem flex rau tag nrho peb cov qib ntaub. Peb tuaj yeem pab koj xaiv qhov tuab tuab thiab xaws rau koj daim ntawv thov khoov xav tau.
