PTFE Daim kab xev Ntsev Txhaj Tshuaj Tiv Thaiv & Marine Application Requirements

PTFE high-temperature daim kab xev yog dav siv nyob rau hauv marine ib puag ncig - nyob rau hauv offshore platforms, ships, coastal cua turbines, thiab ntsev-laden industrial tsam. PTFE txheej nws tus kheej yog heev resistant rau ntsev tsuag. Txawm li cas los xij, daim kab xev tag nrho kev ua tau zoo nyob ntawm ob lub ntsiab lus tsis muaj zog: cov nplaum txheej thiab cov npoo ntawm fiberglass substrate.

Cov tshuaj tsuag ntsev tuaj yeem nkag mus los ntawm cov nplaum sib txuas lossis wick rau hauv cov npoo fiberglass, ua rau poob ntawm adhesion lossis substrate corrosion. Yog li ntawd, kev ntsuam xyuas cov tshuaj tiv thaiv ntsev txhais tau hais tias kev sim seb cov nplaum puas tuav lub zog sib txuas, tiv thaiv dej nqus, thiab tiv thaiv cov hlau hauv qab.

Aokai PTFE tsim PTFE daim kab xev validated rau marine kev pab cuam. Phau ntawv qhia no piav qhia txog cov qauv kev xeem, cov qauv kev lees paub, thiab cov kev cai thov rau qhov chaw muaj ntsev-ntug.

Ntsej Tsuag Test Methods rau PTFE daim kab xev

Standardized kuaj xyuas kom meej tias daim kab xev raws li marine-qib durability. Cov txheej txheem feem ntau yog nruab nrab ntsev tsuag (NSS) rau ISO 9227 lossis ASTM B117.

1. Kev npaj cov qauv

1. Laminate daim kab xev PTFE mus rau ib tug qauv hlau kuaj vaj huam sib luag (xws li, SUS304 stainless hlau los yog lub npaj substrate) siv ib tug roller.

2. Seal daim kab xev npoo nrog waterproof sealant los tiv thaiv qhov txawv txav ntsev pos nkag los ntawm cov npoo txiav. Qhov no simulates tsim nyog installation qhov twg cov npoo muaj kev tiv thaiv.

3. Npaj cov qauv txaus rau kev xeem ua ntej, tom qab kuaj, thiab pab pawg tswj hwm.

2. Ntsev pos huab

• Muab cov hnoos qeev tso rau hauv chav dej ntsev ntawm 35 ° C, 5% NaCl tov.

• Lub sijhawm xeem: 96h, 240h, 500h, 1000h , lossis raws li kev pom zoo.

• Tilt test panels ntawm 15 ° -30 ° los ntawm ntsug rau txawm ntsev pos huab deposition.

3. Kev ntsuam xyuas tom qab raug (ntxuav thiab qhuav)

Daim ntawv thov yuav tsum tau rau Marine & High-Salt-Fog Environments

Rau lub ntiaj teb tiag tiag siv rau ntawm ntug dej hiav txwv platforms, nkoj, ntug hiav txwv cua fais fab chaw, thiab chaw ua lag luam uas muaj ntsev pos huab, PTFE daim kab xev yuav tsum tau raws li cov txheej txheem nruj.

1. Adhesive - silicone PSA yog qhov yuav tsum tau ua

• Silicone siab-rhiab nplaum nplaum: Ultra-low noo noo nqus, zoo ntsev pos huab tsis kam, weatherability. Ua kom muaj kev sib raug zoo rau lub sijhawm ntev thiab tsis corrode stainless hlau.

• Acrylic PSA - Tsis haum: Yooj yim hydrolyzes, plasticizes, thiab poob adhesion nyob rau hauv kub kub thiab hnyav ntsev pos huab. Acrylic yuav tsum tsis txhob siv nyob rau hauv marine ib puag ncig.

2. Substrate thiab ntug tiv thaiv

• Cov ntaub fiberglass yuav tsum tau impregnated nrog PTFE , tsis muaj pinholes. Qhov no tiv thaiv ntsev ingress ntawm capillary ua raws cov fibers, uas yuav ua rau delamination.

• Thaum lub sij hawm installation, kaw daim kab xev sib tshooj thiab cov npoo nrog rau cov huab cua-resistant sealant (xws li, silicone-raws li). Qhov no thaiv cov ntsev pos huab nkag mus rau txoj hauv kev - cov kauj ruam tseem ceeb tshaj plaws rau kev ntseeg tau ntev.

3. Pom zoo cov tshuaj tsuag tshuaj tiv thaiv kab mob

• Yam tsawg kawg 1000h nruab nrab ntsev tsuag (NSS) yam tsis muaj lifting los yog blistering.

• 180 ° tev lub zog tuav ≥80% tom qab 1000h.

• Tsis muaj corrosion ntawm cov hlau hauv qab (los yog cov kab xeb nyob rau hauv cov kev txwv pom zoo).

• Rau cov xwm txheej hnyav heev (xws li, thaj chaw marine atmospheric nrog cov voj voog ntub-qhuav), 2000h NSS lossis cyclic corrosion test (CCT) raug pom zoo.

4. Adaptability rau qhov chaw sib xyaw

• Kub kub + ntsev pos huab: Rau cov pa tso pa tawm los yog cua sov-tracing cable rwb thaiv tsev, ua ke nrog kev laus kev ntsuam xyuas (siab kub + ntsev tsuag).

• UV raug: Sab nraum zoov siv marine yuav tsum tau UV tiv thaiv - cov nplaum yuav tsum tsis txhob chalk lossis debond nyob rau hauv hluav taws xob ultraviolet.

5. Kev teeb tsa thiab kev saib xyuas

• Kev npaj nto: Tag nrho degrease thiab derust bonding nto. Kev sib txuam primer raug pom zoo los txhim kho kev sib txuas ntawm lub ntsej muag thiab thaiv ntsev pos huab nkag.

• Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas cov npoo ntawm daim kab xev thaum lub sij hawm kev pab cuam rau blistering los yog tev. Hloov daim kab xev ua tsis tiav tam sim los tiv thaiv crevice corrosion ntawm cov qauv sib txuas.
