Yuav ua li cas tiv thaiv PTFE daim kab xev tawg nyob rau hauv rov qab khoov thiab qhib

Hauv cov kab ntim khoom, cov tshuab cua sov sealing, thiab cov khoom siv ua zaub mov, PTFE high-temperature daim kab xev yog txuas ntxiv khoov, qhib, thiab nias - lub voj voog tom qab lub voj voog. Nyob rau tib lub sijhawm, txawm tias cov khoom siv ruaj khov no tuaj yeem tsim cov kab nrib pleb lossis tawg.

Vim li cas qhov no tshwm sim? Cov lus teb yog nyob rau hauv peb yam: lub substrate, cov nplaum, thiab yuav ua li cas cov kab xev raug ntsia.

Ntawm Aokai PTFE , peb tau txheeb xyuas ntau pua qhov kev ua tsis tiav. Tsab ntawv xov xwm no qhia txog cov tswv yim ua kom ntev lub neej ntawm daim kab xev thiab tsis txhob tawg ntxov ntxov.

Txhim kho cov qauv - substrate thiab Thickness

Lub substrate ua raws li lub moj khaum, fundamentally txiav txim siab dabtsi yog khoov kuj thiab tsim kua muag zog.

Ntshiab PTFE zaj duab xis nta zoo yoog raws tab sis tsis txaus txhua yam lub zog - nws yooj yim rau kua muag raws li kev ntxhov siab. Iav fiber reinforced PTFE zoo heev txhim kho tensile lub zog, tsim kua muag tsis kam, thiab creep kuj, ua rau nws nyiam xaiv rau dynamic dabtsi yog khoov scenarios.

Thickness kuj tseem ceeb heev. 0.13mm ua haujlwm raws li kev faib kab. Cov kab xev thinner dua 0.13mm yog hloov tau tsis tau muaj zog, yooj yim los tsim microcracks nyob rau hauv rov compression thiab ncab.

Kev pom zoo : Rau feem ntau cov khoom siv dynamic, 0.18mm thickness nrog iav fiber reinforcement yog tus qauv xaiv.

Nyob rau hauv high-cycle daim ntaub ntawv xws li nruam band sealers (ua hauj lwm ntawm 30-60 cycles ib feeb), lub vojvoog dabtsi yog khoov ntawm daim kab xev nyob ib ncig ntawm lub cua sov caij yog ib tug tseem ceeb tsim parameter. Lub vojvoog dabtsi yog khoov me dua 5 hli ua rau muaj kev ntxhov siab hauv zos los ntawm ntau dua 300% piv rau 15 hli vojvoog, ua kom nrawm nrawm pib. Rau cov ntaub ntawv kaw ntom nti, siv cov iav fiber ntau ntxiv PTFE daim kab xev nrog kev tsim kho (tsis yog daim kab xev raws li zaj duab xis) tuaj yeem ua rau lub neej flex 5-10 zaug. Tsis tas li ntawd, tapes nrog ib tug smoother backside tiav ua kom muaj kev sib txhuam sab hauv thaum khoov, ntxiv txo qhov qaug zog. Cov ntaub ntawv teb qhia tau hais tias hloov los ntawm 0.10mm ntshiab PTFE zaj duab xis daim kab xev mus rau 0.18mm iav fiber reinforced daim kab xev ncua kev pab cuam lub neej ntawm 2 lub lis piam mus rau ntau tshaj 6 lub hlis nyob rau hauv high-frequency sealing khoom.

Xaiv Txoj Cai Adhesive

Cov nplaum txuas cov kab xev rau cov khoom siv - ib qho tseem ceeb cuam tshuam rau lub neej kev pabcuam dynamic. Silicone siab-rhiab nplaum nplaum yog qhov kev xaiv zoo tshaj plaws rau dynamic high-temperature ib puag ncig.

Vim li cas silicone yeej rau kev siv khoov:

• Withstands rov khoov thiab vibration yam tsis muaj cracking

• Adapts rau alternating kub thiab txias cycles

• Khaws adhesion txawm tias tom qab ntau txhiab lub voj voog flex

Aokai PTFE qhov kev ntsuam xyuas hauv tsev qhia tau hais tias cov nplaum nplaum silicone khaws ntau dua 90% ntawm lawv qhov pib tev lub zog tom qab 10,000 bending cycles, thaum acrylic-based tapes poob mus txog 50% hauv 5,000 cycles. Rau cov khoom siv khiav 16 teev txhua hnub, qhov sib txawv no txhais mus rau lub hlis ntawm kev pabcuam ntxiv.

Rau PTFE tapes siv rau reciprocating sealing tuav (xws li, ntsug daim ntawv sau cov cav tov), ​​cov nplaum yuav tsum tau tiv 'txias txaus' - maj mam deformation nyob rau hauv siab. Cov nplaum silicone tsis zoo tuaj yeem nyem tawm ntawm daim kab xev tom qab siv txuas ntxiv, ua rau cov nplaum seem ntawm cov khoom lossis cov khoom sib khi. High crosslink-density silicone nplaum nrog cov qauv thermosetting tswj qhov kev ruaj ntseg txawm tias ntawm 250 ° C. Thaum xaiv PTFE daim kab xev rau cov ntawv thov ntau zaus, thov cov ntaub ntawv ntawm 'shear adhesion tsis ua hauj lwm kub' (SAFT) thiab ' tuav lub hwj chim' - qhov tseem ceeb tshaj 260 ° C thiab tshaj 24 teev ntawm 200 ° C qhia tias muaj cov nplaum nplaum.

Txhim kho thiab kho kom raug rau lub neej ntev

Cov khoom lag luam premium xa cov kev ua tau zoo tshaj plaws tsuas yog nrog kev siv thiab tu kom zoo.

Kev Kho Ntog Ua Ntej Daim Ntawv
Thov Ua kom huv thiab qhuav cov khoom siv nrog cov dej tsis muaj ethanol lossis isopropanol. Roj stains, plua plav, thiab noo noo tsis muaj zog adhesion thiab ua rau ntxov tev. Siv 800-1000 grit nplua sandpaper kom maj mam txhuam cov hlau du - qhov no txhim kho kev sib cuam tshuam thiab txhim kho cov nyhuv nplaum.

Tswb-Free Installation thiab Edge Reinforcement
Py daim kab xev ib txwm tsis ncab. Tensile stress ua rau shrinkage thiab warping thaum lub sij hawm thermal cycling. Nias sib npaug los ntawm qhov chaw mus rau ob sab nrog lub scraper kom tshem tawm cov npuas npuas. Ua kom muaj zog thiab ua kom cov npoo - los yog siv cov khoom siv kub-resistant silicone sealant - los tiv thaiv ntug nqa.

Kev hloov kho ua haujlwm

• Ua haujlwm kub qis dua 260 ° C - qhov kev txwv ntev ntawm silicone nplaum

• Tsis txhob overheating hauv zos (kub chaw)

• Tiv thaiv kom tsis txhob muaj kev siv tshuab ntau dhau uas tuaj yeem tsoo cov kab xev

• Ua kom huv si ib puag ncig kom txo tau kev puas tsuaj los ntawm plua plav thiab hlau

Kev tshuaj xyuas tsis tu ncua thiab hloov raws sij hawm
PTFE daim kab xev yog ib qho khoom siv hauv kev ua haujlwm zoo. Hloov nws tam sim ntawd thaum ib qho ntawm cov no tshwm sim:

• Ntug warping los yog lifting

• Carbonization, yellowing, los yog scorch marks

• Adhesive tsis ua hauj lwm, overflow, los yog hloov chaw

• Pom pom kev puas tsuaj, microcracks, lossis pinholes

Summary - Cov ntsiab lus tseem ceeb los tiv thaiv daim kab xev tawg

Hauv cov ntsiab lus , tiv thaiv kev tawg thiab tawg ntawm PTFE daim kab xev kub kub nyob rau hauv rov qab khoov los rau peb xaiv: iav fiber reinforced substrate, 0.18mm thickness (los yog tsim nyog rau koj load), thiab silicone nplaum. Kev txhim kho kom raug - qhov chaw huv si, tsis muaj qhov nro, kev txhawb nqa ntug - ob npaug rau lub neej zoo.

Rau kev siv lub voj voog siab (cov sealers, presses, conveyors nrog nruj radii), xav txog qib woven iav fiber reinforced thiab tshuaj xyuas txhua hli rau microcracks.
