● Qhov sib txawv ntawm kev pabcuam lub neej
Ntau hom raw khoom
Galvanized hlau PPGI yog tag nrho coated nrog zinc, thaum Galvalume steel PPGL yog coated nrog txhuas, zinc thiab ib tug me me ntawm silicone. Qhov no muab superior corrosion kuj thiab durability piv rau galvanized coatings. Qhov no yog qhov sib txawv loj tshaj plaws ntawm PPGI steel thiab PPGL.
Txij li qhov tshwj xeeb lub ntiajteb txawj nqus ntawm txhuas yog me dua li ntawm zinc, qhov hnyav ntawm aluminium-zinc txheej ntawm PPGL yuav me dua nyob rau hauv tib lub txheej thickness. Qhov no kuj txhais tau tias tib qhov hnyav ntawm Al-Zn txheej tuaj yeem npog 3% ntau qhov chaw tshaj PPGI. Qhov no tseem ceeb distinguishes qhov txawv ntawm ob.
Qhov sib txawv ntawm kev pabcuam lub neej
Ob leeg zinc thiab aluminium-zinc txheej txheej pab tiv thaiv cov hlau los ntawm xeb thiab txuas ntxiv cov khoom lag luam. Thaum siv PPGI, lub hauv paus hlau tuaj yeem raug puas tsuaj thaum lub zinc txheej corrodes. Kev pab lub neej ntawm Galvanized PPGI panels yog kwv yees li 10 mus rau 15 xyoo.
Thaum siv aluminium-zinc alloy ntawm PPGL, cov ntaub ntawv nplua nuj aluminium yuav corrode maj mam, thaum zinc-nplua nuj qhov chaw yuav corrode nyiam. Qhov no muab kev tiv thaiv corrosion ntau dua li PPGI's zinc txheej. Lub neej kev pab cuam ntawm PPGL tuaj yeem ncav cuag peb npaug ntawm PPGI. Hais txog kev pabcuam lub neej, ntau tus neeg siv khoom xaiv PPGL
Qhov txawv txav
PPGL nto zoo li smoother dua PPGI nto. Txij li thaum txhuas adheres zoo dua zinc, PPGL yuav tsis xav tau tib lub painting pretreatment li galvanized ntawv. Tsis muaj ntau qhov sib txawv ntawm qhov tsos.
Kub thiab corrosion kuj
Nyob rau hauv cov nqe lus ntawm kev siv, PPGL muaj cov cua kub zoo dua li PPGI thiab tuaj yeem tiv taus kub txog 315 degree. Vim tias PPGG muab kev tiv thaiv corrosion zoo dua los ntawm cov hlau tuab, txheej hauv paus yog tiv thaiv ntxiv los ntawm kev yaig. Txawm li cas los xij, cov npoo txiav ntawm PPGL tsis muaj kev tiv thaiv tsawg dua vim tias cov qauv honeycomb ntawm cov txheej tsis zoo tiv thaiv cov npoo raug. Cov npoo npog no tuaj yeem coated rau kev tiv thaiv ntxiv.
Kev siv PPGI thiab PPGL
PPGI thiab PPGL yog siv nyob rau hauv ntau yam vov tsev thiab siding daim ntaub ntawv. Txij li thaum PPGL muaj kev tiv thaiv corrosion zoo dua, nws yog qhov tsim nyog rau qhov hnyav sab nraum zoov xws li thaj chaw ntug dej hiav txwv raug dej hiav txwv. PPGL kuj tseem muaj cov cua sov ua haujlwm zoo heev. Thaum tshav kub kub reflectivity ntawm PPGL yog siab heev, ob zaug ntawm galvanized hlau. Cov neeg feem ntau siv nws ua cov khoom siv hluav taws xob rwb thaiv tsev.
Nqe sib txawv
Vim muaj kev txhim kho kev ua tau zoo. Tus nqi ntawm PPGL feem ntau yog me ntsis siab dua PPGI. Lub neej kev pab cuam ntawm PPGL ntev dua li ntawm PPGI, yog li ntau tus neeg siv khoom xaiv PPGL. Thaum koj xaiv ntawm ob yam khoom, koj tuaj yeem xav txog ntau yam xws li koj tus kheej siv thiab siv ib puag ncig. Kuv vam tias koj tuaj yeem xaiv cov khoom tsim nyog rau koj.
