Airgel Coatings rau Deterioration Defense thiab Thermal Administration
(Airgel Coatings rau Kev Tiv Thaiv Corrosion thiab Thermal Management)
Dab tsi yog Airgel Coatings? .
Airgel npog yog cov khoom siv hnyav hnyav ua los ntawm cov gels qhov twg cov kua tshuaj hloov pauv nrog roj. Qhov no ua rau lawv zoo li daim txhuam cev zoo li ntim nrog cov hnab pa me me. Raws li qhov tshwm sim ntawm qhov no, lawv yog cov zoo tshaj plaws insulators lees paub. Lawv kuj tiv taus noo noo, tshuaj, thiab cua sov. Thaum siv raws li txheej txheej, aerogels tsim ib qho kev tiv thaiv kev tiv thaiv nyob rau thaj tsam hlau. Qhov kev thaiv no pab tshem tawm xeb thiab tswj cov cua sov los ntawm kev txav los yog tawm sai sai. Cov khoom xyaw tseem ceeb feem ntau muaj silica lossis cov ntawv tshiab xws li graphene-based aerogels. Cov versions siab heev no muab kev ua haujlwm zoo dua. Koj tuaj yeem kawm paub ntxiv txog kev tshawb fawb txog kev tshawb fawb tom qab cov super-insulating vaj tse nyob ntawm qhov txuas no.
Vim li cas thiaj siv Airgel Coatings rau Rust Security thiab Thermal Management? .
Steel Cheebtsam qhia rau ntub dej, ntsev, los yog huab cua hnyav heev yuav hnav tam sim ntawd. Cov tshuaj pleev ib ce lossis cov ntaub qhwv tuaj yeem txo qhov no tab sis feem ntau poob qis hauv cov mob hnyav. Airgel npog kho qhov no los ntawm kev ua kom qhuav, txheej ruaj khov uas thaiv dej thiab oxygen– ob lub hauv paus tseem ceeb ua rau corrosion. Nyob rau tib lub sijhawm, lawv tuav cov cua sov tshwj xeeb zoo. Lawv cov nanostructure ntxiab huab cua kom ua tau zoo uas hloov hluav taws xob mus qis heev. Qhov no ntxaib feature ua rau lawv zoo meej rau cov sectors uas ob qho tib si deterioration thiab kub tswj teeb meem. Piv txwv li, nkoj, cev, thiab offshore platforms cuam tshuam nrog kev cuam tshuam tsis tu ncua rau cov dej ntsev thiab qhov kub ntawm qhov kub thiab txias heev. Airgel tiav kev ruaj ntseg tiv thaiv ob qho teeb meem hauv ib qho mus. Tias yog vim li cas cov neeg tsim qauv tig mus rau lawv ntau zaus.
Tsuas yog Yuav Ua Li Cas Airgel Coatings Applied? .
Kev siv airgel npog yog qhov nyuaj dua li koj tuaj yeem ntseeg. Ua ntej, qhov saum npoo yuav tsum tau ntxuav kom huv si kom tshem tawm cov roj, hmoov av, los yog xim qub. Ces, cov khoom siv airgel– feem ntau nyob rau hauv ib tug slurry los yog sprayable hom– yog siv los ua cov txhuam hniav, rollers, los yog sprayers. Qee qhov kev hloov pauv tuaj raws li cov txheej txheem ua ntej uas tuaj yeem qhwv ib ncig ntawm cov kav dej lossis lub tank cia. Cov felts no yooj yim teeb tsa thiab txiav kom loj. Ib qho kev qhia tob rau kev txhim kho airgel felts hauv cov phab ntsa yog muaj nyob rau ntawm lub vev xaib no. Tom qab ntawv thov, qhov kawg dries thiab bonds snugly rau saum npoo. Nws tseem muaj ntau yam, yog li nws yuav tsis tawg thaum cov hlau nthuav dav lossis tau txais nrog kev hloov kho kub. Kev tu ncua raug txo, thiab txheej yuav kav ntev li ntau xyoo yam tsis tau tev tawm lossis ua kom muaj zog.
Daim ntawv thov ntawm Airgel Coatings rau Corrosion Protection thiab Thermal Administration .
Cov kev ua tiav no yog siv hauv ntau qhov chaw tiag tiag. Hauv cov roj thiab roj sector, pipelines mus hla cov suab puam thiab hiav txwv ib yam nkaus. Airgel tiav ua kom lawv tsis txhob xeb thiab txo qhov sov sov thaum thauj cov kua kub. Hauv cov huab cua hauv hiav txwv, nkoj hulls thiab decks tseem tiv thaiv los ntawm ntsev tsuag thaum tseem nyob txias rau lub caij ntuj sov. Cov tuam txhab Aerospace siv lawv ntawm lub dav hlau qhov chaw los saib xyuas qhov kub thiab txias hloov pauv ntawm qhov siab siab. Kuj tseem nyob hauv lub zog tauj dua tshiab, Hnub ci thermal tshuab nyob ntawm airgel rwb thaiv tsev kom sov hauv cov neeg nyiam. Tshaj li kev lag luam siv, cov qauv hauv qhov chaw txias ua rau siv cov txheej txheem aerogel-raws li phab ntsa los txiav cov nqi cua sov thiab tiv thaiv kev tsim vaj tsev xeb.. Kev hloov pauv ntawm cov khoom siv no txuas ntxiv mus. Rau qhov dav xav txog raws nraim li cas nanomaterials zoo li graphene hloov pauv ntau qhov chaw, saib qhov peev txheej no.
Cov lus nug nquag nug txog Airgel Coatings rau Rust Security thiab Thermal Management .
1. Puas yog airgel finishings kim?
Lawv raug nqi ntau dua ua ntej tshaj li cov xim tsis tu ncua, tab sis lawv kav ntev dua thiab txo cov nqi kho mob tsawg. Nrog sijhawm, lawv khaws nyiaj ntsuab.
2. Lawv tuaj yeem siv sab nraum zoov?
Yog lawm. Lawv tsim los saib xyuas lub teeb UV, dej nag, thiab kub viav vias tsis tawg.
