I. Yam ntxwv ntawm Aluminium Sheet Hlau thiab Xim Adhesion
- Aluminium ntawv hlau muaj qee yam tshwj xeeb uas muaj kev cuam tshuam tseem ceeb ntawm seb nws puas tuaj yeem pleev xim. Qhov saum npoo ntawm aluminium yog tus du, uas yuav ua rau nws nyuaj rau cov xim kom ua raws. Txawm li cas los xij, aluminium nws tus kheej muaj kev tiv thaiv corrosion zoo, uas tseem yuav tsum tau xav txog hauv cov txheej txheem tha xim. Piv txwv li, hauv qee cov ntawv thov kev lag luam, cov khoom siv txhuas tuaj yeem nyob hauv qhov zoo txawm tias tsis muaj kev kho xim. Txawm li cas los xij, yog tias cov ntawv txhuas hlau yuav tsum tau pleev xim rau, qhov teeb meem ntawm qhov chaw du yuav tsum tau kov yeej kom ntseeg tau tias cov xim tuaj yeem ua rau nws ruaj khov.
II. Hom xim uas tuaj yeem siv rau cov ntawv txhuas hlau
- Muaj ntau ntau hom xim uas tuaj yeem siv rau aluminium ntawv hlau. Thawj yog cov xim acrylic, uas muaj cov huab cua tsis zoo thiab tuaj yeem tuav tau zoo thiab kev tiv thaiv hauv cov huab cua sib txawv. Nws muaj qee yam kev sib raug zoo nrog cov aluminium nto thiab tuaj yeem ua raws li cov ntawv txhuas hlau tom qab kev kho kom zoo.
- Epoxy xim kuj yog ib qho kev xaiv. Epoxy xim muaj zog adhesion thiab muaj peev xwm muab kev tiv thaiv zoo, tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw uas yuav tsum tau hnav tsis kam thiab tshuaj corrosion kuj. Rau daim ntawv thov ntawm cov ntawv txhuas hauv cov khoom siv los yog cov chaw sab nraum zoov, epoxy xim tuaj yeem tiv thaiv aluminium nto ntawm corrosion thiab hnav.
3. Kev kho deg ua ntej pleev xim rau cov ntawv txhuas
- Ua ntej pleev xim rau cov ntawv txhuas, kev npaj kom zoo yuav tsum tau ua. Qhov no suav nrog kev ntxuav qhov chaw thiab tshem tawm cov impurities xws li roj, plua plav thiab oxides. Piv txwv li, nws tuaj yeem ntxuav nrog ib lub tshuab ntxuav tshwj xeeb thiab tom qab ntawd yaug nrog dej huv.
- Kev xuab zeb kuj yog ib kauj ruam tseem ceeb. Sanding tuaj yeem ua rau qhov roughness ntawm aluminium nto, yog li txhim kho cov adhesion ntawm cov xim. Txawm li cas los xij, qib ntawm sanding yuav tsum tau txiav txim siab raws li cov kev cai tshwj xeeb thiab kev siv ib puag ncig ntawm cov ntawv txhuas.
- Lwm txoj kev kho saum npoo yog siv cov primer. Cov primer tuaj yeem tsim cov txheej txheem kev hloov pauv ntawm cov txheej txheem txhuas los txhim kho kev sib txuas ntawm cov xim thiab cov txhuas. Qee cov primers tshwj xeeb yog tsim tshwj xeeb rau cov khoom siv txhuas kom zoo dua rau cov khoom siv tshuaj lom neeg thiab cov yam ntxwv saum npoo ntawm txhuas.
4. Kev txhim kho ntawm cov ntawv txhuas tom qab pleev xim
- Thaum daim ntawv txhuas tau ua tiav tiav, nws qhov kev ua tau zoo yuav raug txhim kho hauv ntau yam. Hais txog qhov tsos, xim tuaj yeem ua rau txhuas ntawv muaj ntau yam xim sib txawv thiab glosses kom tau raws li qhov sib txawv ntawm qhov zoo nkauj thiab kev xav tau zoo nkauj.
- Raws li kev tiv thaiv kev ua haujlwm, xim tuaj yeem txhim kho corrosion kuj ntawm txhuas ntawv. Piv txwv li, nyob rau hauv ib qho chaw ntub dej los yog corrosive, cov xim txheej tuaj yeem ua qhov thaiv kom tsis txhob ya raws thiab corrosive tshuaj los ntawm kev tiv tauj cov txhuas nto, yog li txuas ntxiv lub neej kev pab cuam ntawm cov ntawv txhuas. Nyob rau tib lub sijhawm, xim tuaj yeem txhim kho qhov hnav tsis kam ntawm aluminium ntawv. Rau qee cov ntawv txhuas cov khoom uas feem ntau raug kev sib txhuam los yog kev sib tsoo, xim tuaj yeem txo qhov hnav.
Hauv cov ntsiab lus, cov ntawv txhuas tuaj yeem pleev xim rau, tab sis nws yog ib qho tsim nyog yuav tsum xaiv cov xim zoo nkauj thiab ua qhov kev kho saum npoo kom zoo los xyuas kom meej cov nyhuv ntawm cov xim thiab kev txhim kho ntawm cov ntawv txhuas tom qab pleev xim.
