Offshore platforms, ships, coastal cua turbines, thiab marine engineering khoom ntsib ib tug yeeb ncuab relentless: ntsev tsuag . Nws corrodes hlau, degrades adhesives, thiab shortens lub neej khoom. Ua tau PTFE daim kab xev ntsuas kub
Cov lus teb luv luv: PTFE substrate nws tus kheej yog zoo indestructible nyob rau hauv ntsev tsuag. Tab sis daim kab xev tag nrho kev ua tau zoo nyob ntawm ntau yam ntawm cov nplaum thiab kev teeb tsa zoo .
Aokai PTFE tau muab PTFE tapes rau marine daim ntaub ntawv rau xyoo. Kab lus no piav qhia txog kev siv tshuaj tua kab ntsev, kev xaiv cov nplaum, kev npaj nto, kev sib khi ntawm ntug, thiab kev saib xyuas - yog li koj tuaj yeem ua tiav kev ntseeg tau ntev hauv cov ntug dej hiav txwv thiab ntug dej hiav txwv.
Ntsev Txau Resistance – PTFE Substrate vs. Adhesive
1. PTFE Substrate – Ua tiav Resistant
PTFE nthuav tawm cov tshuaj inertness zoo heev. Nws yog qhov tsis zoo nrog dej hiav txwv thiab ntsev tsuag, nrog rau qhov nqus dej hauv qab 0.01% . Nws kuj tseem xa cov UV zoo heev thiab huab cua tsis kam. Lub PTFE substrate nws tus kheej yog kiag li resistant rau ntsev tsuag - tsis muaj corrosion, degradation, los yog poob ntawm lub cev.
Cov ntaub ntawv tseem ceeb: PTFE qhia tias tsis muaj qhov ntsuas qhov hnyav hloov lossis qhov degradation tom qab ntau txhiab teev hauv cov tshuaj tsuag ntsev.
2. Adhesive – Qhov Txuas Tsis Muaj Zog
Zuag qhia tag nrho ntsev tsuag tsis kam ntawm daim kab xev yog nyob ntawm cov nplaum hom:
Hom nplaum
Ntsev Txau Resistance
Haum rau Marine
Silicone PSA
Zoo heev - withstands 500-1000+ teev nruab nrab ntsev tsuag tshuaj ntsuam; Peev zog tuav> 80%
✅ Nyiam xaiv
Acrylic PSA
Tsis zoo - hydrolysis, plasticizer migration, tseem ceeb adhesion poob nyob rau hauv siab kub / av noo / ntsev tsuag
❌ Tsis pom zoo
Vim li cas silicone yeej: Qhov sib txuas ntawm cov khoom siv silicone yog qhov muaj zog hydrophobic, UV-resistant, thiab ruaj khov hla -70 ° C txog 260 ° C. Nws tuav adhesion thiab yoog raws txawm tias tom qab siv ntsev tsuag ntev ntev.
Yog vim li cas acrylic tsis: Pa acrylic adhesives undergo hydrolysis nyob rau hauv high humidity ib puag ncig. Cov tshuaj ntsev ua kom nrawm nrawm ntawm ester bonds, ua rau cov nplaum muag muag, kev tsiv teb tsaws, thiab qhov kawg ntawm daim ntawv cog lus tsis ua haujlwm.
Aokai PTFE tsuas yog siv tau zoo silicone PSA rau peb marine-qib PTFE tapes. Peb tau lees paub peb cov kab xev los ntawm kev ywj pheej 1000-teev nruab nrab ntsev tsuag tshuaj ntsuam nrog> 80% tev lub zog tuav - cov ntaub ntawv muaj nyob rau ntawm kev thov.
Daim ntawv thov yuav tsum tau rau Marine & High Salt Spray Environments
Rau cov kev pab cuam txhim khu kev qha ntawm ntug dej hiav txwv platforms, cov hlab ntsha, cov chaw ua haujlwm ntawm ntug dej hiav txwv cua, thiab cov khoom siv hauv marine engineering, yuav tsum muaj kev tswj xyuas tag nrho ntawm cov khoom siv, kev tsim, tsim, thiab kev saib xyuas.
1. Kev xaiv cov khoom siv
Kev xav tau
Specification
Adhesive
Silicone-raws li, kub tsis kam ≥260 ° C, lub sij hawm ntev resistant rau high humidity, ntsev tsuag, thiab UV
Substrate
Ntshiab PTFE zaj duab xis los yog zoo PTFE-impregnated fiberglass npuag - siab txhua yam muaj zog, tsis tshua muaj permeability, superior weatherability
Kev siv hluav taws xob rwb thaiv tsev
Xaiv daim kab xev thickness raws li qib voltage; account rau creepage nrug los tiv thaiv nto creepage nyob rau hauv ntsev tsuag thiab damp tej yam kev mob
2. Kev kho deg
Ua tib zoo tshem cov roj, ntsev, thiab xeb tawm ntawm qhov chaw sib txuas. Xyuas kom qhov chaw qhuav tag.
So dua nrog cov dej tsis muaj dej ethanol lossis acetone kom txog thaum tsis muaj cov kab mob.
Rau cov hlau nto: Pom zoo kom roughen los ntawm sandblasting los yog sanding (80-120 grit) los txhim kho mechanical anchoring quab yuam.
Rau cov xwm txheej hnyav: Thov silicone primer ntxiv - zoo heev txhim kho qhov pib adhesion thiab lub sij hawm ntev ntsev tsuag tsis kam ntawm cov hlau.
Vim li cas qhov no tseem ceeb: Daim kab xev-substrate interface yog qhov tsis muaj zog tshaj plaws hauv cov tshuaj tsuag ntsev. Kev kho deg tsis txaus tso cai rau ntsev tsuag kom nkag mus rau hauv qhov sib txuas, ua rau corrosion ntawm cov hlau substrates lossis delamination ntawm cov nplaum txheej.
3. Kev tsim kho txheej txheem
Kauj ruam

Raws li kev paub dhau los - tsis txhob tos kom pom qhov ua tsis tiav
Nyob rau hauv cov ntsiab lus , PTFE high-temperature daim kab xev yog inherently zoo heev rau marine thiab siab ntsev tsuag ib puag ncig - lub PTFE substrate resists ntsev, UV, thiab noo noo zoo kawg nkaus. Txawm li cas los xij, daim kab xev lub sij hawm ntev kev cia siab nyob ntawm cov nplaum. Silicone PSA yog qhov kev xaiv nkaus xwb rau kev siv ntug dej hiav txwv thiab ntug dej hiav txwv, nrog pov thawj 500-1000+ teev ntsev tshuaj tsuag kev ua tau zoo (> 80% tev tuav). Acrylic PSA yuav ua tsis tiav hauv lub hlis.
Tshaj li kev xaiv cov nplaum, kev vam meej yuav tsum tau ua kom huv si saum npoo thiab roughening, daim ntawv thov tsis muaj npuas, thiab - qhov tseem ceeb tshaj plaws - ntug sealing nrog silicone sealant los thaiv cov ntsev tsuag infiltration. Kev tshuaj xyuas tsis tu ncua thiab teem caij hloov pauv ua tiav lub tswv yim kev ntseeg tau.
