iav pwm (tseem hu ua "glass deterioration") yog cov pos huab dawb, zaj sawv-zoo li lossis taw tes-zoo li corrosion uas tshwm sim ntawm cov iav vim ntev - lub sij hawm ya raws lossis tshuaj yaig. Nws feem ntau pom nyob rau hauv qhov chaw ntub dej lossis cov khoom siv iav uas tsis raug cai.

I. Ua rau iav Pwm
Environmental yam
Ntev ntev - raug rau qhov ntub dej thiab siab - qhov kub thiab txias (xws li chav dej, chav ua noj, hauv qab daus).
Thaum cov iav tau muab tso rau hauv qhov chaw cia, cov dej vapor nkag mus rau hauv qhov khoob ntawm lub khob, ua rau qhov chaw corrosion.
Chemical yam
Cov sodium -calcium silicate nyob rau hauv cov muaj pes tsawg leeg ntawm iav reacts nrog noo noo los tsim alkaline tshuaj (xws li sodium hydroxide), uas corrode lub nto ntawm lub khob.

Cov khoom seem ntawm cov tshuaj ntxuav tu lossis cov khoom muaj paug (xws li cov kua qaub los nag) ua kom cov pwm loj hlob tuaj.
Ii. Txoj kev los daws cov iav moldy
Mild pwm (foggy dawb me ntsis los yog zaj sawv qauv)
Dawb vinegar los yog citric acid tov
Soak thaj tsam pwm nyob rau hauv 1: 1 tov ntawm dawb vinegar / dej los yog 5% citric acid rau 10 mus rau 15 feeb, ces so nws nrog ib tug mos ntaub thiab thaum kawg yaug nrog dej huv.
Lub hauv paus ntsiab lus: Cov tshuaj acidic neutralize cov khoom alkaline corrosive ntawm iav nto.
Baking soda paste
Sib tov baking soda nrog dej los ua ib qho muab tshuaj txhuam, muab tso rau hauv cov pwm me me, maj mam txhuam nrog cov txhuam txhuam mos mos thiab tom qab ntawd yaug.
Tshwj xeeb iav pwm tshem tawm
Cov khoom lag luam uas muaj pwm tshem tawm (muaj hydrofluoric acid lossis ammonium fluoride) yuav tsum tau siv raws li cov lus qhia thiab cov hnab looj tes yuav tsum hnav thaum ua haujlwm.
2. Cov pwm nruab nrab (qhov chaw lossis flake corrosion)
Polishing thiab restoration
Siv iav polishing muab tshuaj txhuam los yog lub tsheb polishing wax ua ke nrog lub tshuab polishing / cov ntaub mos los txhuam cov pwm pwm thiab rov ua kom pom tseeb.
Nco tseg: Qhov no tsuas yog siv tau rau cov iav uas tsis yog -coated. Polishing coated iav yuav ua rau cov txheej txheem puas.
Tshuaj txhuam hniav ntxuav
Siv cov tshuaj txhuam hniav uas muaj cov abrasives rau cov pwm me me thiab so ntau zaus hauv cov voj voog ncig nrog daim txhuam cev. Qhov no yog tsim rau thaj chaw me me ntawm pwm.
3. Cov pwm hnyav (qhov tsis sib xws corrosion)
Yog tias pwm tau ua rau lub ntsej muag ntawm lub khob puas lawm thiab kev tu zoo tib yam tsis tuaj yeem kho nws, lub iav yuav tsum tau hloov.
Iii. Kev ntsuas los tiv thaiv iav kom tsis txhob muaj pwm
Cia tej yam kev mob
Cov iav yuav tsum khaws cia kom ncaj thiab tsis muab tso rau. Daim ntawv qhuav los yog anti- pwm gaskets yuav tsum tau siv los cais cov txheej.
Khaws lub tsev khaws khoom kom zoo- qhov cua thiab qhuav (cov av noo tsawg dua lossis sib npaug li 60%), thiab nyob deb ntawm qhov chaw acidic thiab alkaline.
Kev tu txhua hnub
Tsis tu ncua ntxuav lub khob nrog cov tshuaj ntxuav tes tsis tu ncua (xws li cov tshuaj ntxuav tais diav) kom tsis txhob muaj cov tshuaj alkaline residue (xws li dej xab npum).
Tom qab siv, chav dej iav yuav tsum tau qhuav tam sim ntawd thiab txheej txheej hydrophobic (xws li nano anti{0}}fogging agent) tuaj yeem siv tau.
Xaiv cov iav tiv thaiv- pwm
Xaiv cov iav uas tau dhau los tiv thaiv- kev kho pwm (xws li iav laminated lossis iav insulating nrog cov tshuaj tiv thaiv- pwm ntxiv).
Iv. Cov kev ceev faj
Kev tiv thaiv kev nyab xeeb
Hnav hnab looj tes thiab tsom iav thaum siv cov kua qaub los yog fluorine- muaj cov tshuaj ntxuav kom tsis txhob sib cuag ntawm daim tawv nqaij.
Xeem ua ntej
Ua ntej ntxuav, sim thaj tsam me me hauv lub ces kaum ua ntej kom tsis txhob muaj kev puas tsuaj loj -.
Coated iav
Tsis txhob ntxuav nrog cov kua qaub thiab cov tshuaj abrasive los tiv thaiv kev puas tsuaj rau txheej txheej (xws li Low-E iav).
