Cov Galvanized Coil "Hloov" mus rau hauv Xim - PPGI Coil li cas?

Hauv ntau qhov chaw xws li kev tsim kho thiab cov khoom siv hauv tsev, PPGI Steel Coils siv dav vim lawv cov xim nplua nuj thiab kev ua tau zoo heev. Tab sis koj puas paub tias nws "tus ua ntej" yog Galvanized Steel Coil? Cov hauv qab no yuav qhia txog cov txheej txheem ntawm Galvanized Sheet Coil tsim rau hauv PPGI Coil.

1. Nkag Siab Txog Galvanized Coils thiab PPGI Coils

Cov Chaw Tsim Khoom Galvanized Coils txheej cov coils nrog ib txheej zinc rau ntawm qhov chaw, uas feem ntau ua haujlwm tiv thaiv xeb thiab ntev lub neej kev pabcuam ntawm cov hlau. PPGI steel coils siv galvanized steel coils ua lub substrate. Tom qab ib qho kev ua tiav, cov txheej txheem organic tau siv rau lawv qhov chaw. Nws tsis tsuas yog khaws cov khoom tiv thaiv xeb ntawm galvanized steel coils tab sis kuj ntxiv ntau yam khoom zoo heev xws li kev zoo nkauj thiab kev tiv thaiv huab cua.

 

2. Cov Kauj Ruam Tseem Ceeb Rau Lub Hoobkas Galvanized Steel

(1) Cov Txheej Txheem Ua Ntej - Degreasing: Qhov saum npoo ntawm cov hlau galvanized yuav muaj cov khoom tsis huv xws li roj thiab hmoov av. Cov pa phem no raug tshem tawm los ntawm cov tshuaj alkaline lossis cov neeg sawv cev degreasing tshuaj kom ntseeg tau tias muaj kev sib xyaw zoo dua ntawm cov txheej tom ntej nrog cov substrate. Piv txwv li, kev siv cov tshuaj degreasing uas muaj surfactant tuaj yeem ua rau cov roj molecules puas tsuaj tau zoo.

Kev Kho Mob Hloov Tshuaj: Cov feem ntau suav nrog kev kho chromization lossis kev kho passivation tsis muaj chromium. Nws tsim cov zaj duab xis tshuaj nyias nyias rau ntawm qhov chaw ntawm cov txheej galvanized, lub hom phiaj yog txhim kho kev sib txuas ntawm cov khoom siv thiab cov xim thaum txhim kho kev tiv thaiv corrosion. Cov zaj duab xis no zoo li "choj", ua rau cov xim txuas nrog lub kauj hlau galvanized.

(2) Cov Txheej Txheem Pleev Xim - Txheej Txheem Primer: Cov primer yog siv rau ntawm cov kauj galvanized uas tau kho ua ntej los ntawm kev siv cov txheej txheem roller lossis lwm txoj hauv kev. Lub luag haujlwm tseem ceeb ntawm cov primer yog los tiv thaiv xeb. Nws muaj cov xim tiv thaiv xeb thiab cov resins, uas tuaj yeem cais cov kev sib cuag ntawm cov dej noo, oxygen, thiab cov txheej galvanized. Piv txwv li, epoxy primer muaj kev nplaum zoo thiab tiv thaiv xeb.

Txheej Txheej Sab Saum Toj: Xaiv cov txheej txheej sab saum toj ntawm ntau xim thiab kev ua tau zoo rau kev txheej raws li qhov xav tau. Cov txheej txheej sab saum toj tsis yog tsuas yog muab cov xim nplua nuj rau PPGI kauj xwb tab sis kuj muab kev tiv thaiv xws li kev tiv thaiv huab cua thiab kev tiv thaiv hnav. Piv txwv li, polyester txheej txheej sab saum toj muaj cov xim ci thiab tiv thaiv UV zoo, ua rau nws tsim nyog rau kev tsim kho sab nraum zoov. Qee cov kauj xim-coated kuj muaj xim rov qab los tiv thaiv sab nraub qaum ntawm lub substrate los ntawm kev puas tsuaj ib puag ncig.

(3) Ci thiab Kho Cov hlau pleev xim nkag mus rau hauv lub cub tawg ci thiab ci ntawm qee qhov kub (feem ntau yog 180 ℃ - 250 ℃). Qhov kub siab ua rau cov roj hmab hauv cov xim dhau los ua qhov sib txuas, khov kho rau hauv zaj duab xis thiab tsim cov txheej txheem ruaj khov. Lub sijhawm ci thiab qhov kub yuav tsum tau tswj hwm kom meej. Yog tias qhov kub qis dhau lossis lub sijhawm tsis txaus, zaj duab xis xim yuav tsis kho tag nrho, cuam tshuam rau kev ua tau zoo; yog tias qhov kub siab dhau lossis lub sijhawm ntev dhau, zaj duab xis xim yuav tig daj thiab nws cov kev ua tau zoo yuav poob qis.

(4) Kev Ua Tom Qab (Xaiv Tau) Qee cov PPGI Steel coils raug ua tom qab kev ua xws li embossing, laminating, thiab lwm yam tom qab tawm hauv qhov cub. Embossing tuaj yeem ua rau qhov zoo nkauj thiab kev sib txhuam ntawm qhov chaw, thiab laminating tuaj yeem tiv thaiv qhov chaw txheej thaum lub sijhawm thauj mus los thiab ua kom tsis txhob khawb.

 

3. Cov txiaj ntsig thiab kev siv ntawm PPGI Steel Coils Los ntawm cov txheej txheem saum toj no, cov hlau galvanized coil tau ua tiav "hloov pauv" mus rau hauv PPGI coil. PPGI Coil yog ob qho tib si zoo nkauj thiab siv tau. Hauv kev tsim kho, lawv tuaj yeem siv rau phab ntsa sab nraud thiab ru tsev ntawm cov chaw tsim khoom. Nrog ntau yam xim, lawv ruaj khov thiab tsis ploj. Hauv kev ua haujlwm ntawm cov khoom siv hauv tsev, xws li lub tub yees thiab lub plhaub cua txias, lawv ob leeg zoo nkauj thiab hnav - tiv taus. Nws cov kev ua tau zoo heev ua rau nws nyob hauv txoj haujlwm tseem ceeb hauv ntau yam lag luam. Los ntawm galvanized coil mus rau PPGI coil, qhov kev hloov pauv yooj yim zoo li cuam tshuam nrog cov thev naus laus zis meej thiab cov mis tshuaj ntsuam xyuas. Txhua qhov txuas ntau lawm yog qhov tseem ceeb, thiab lawv ua ke tsim cov kev ua tau zoo zoo ntawm PPGI coil, ntxiv xim thiab yooj yim rau kev lag luam niaj hnub thiab lub neej.
