PRE-painted GALVANIZED STEEL COIL

PRE-painted GALVANIZED STEEL COIL
Nqe lus piav qhia:PPGI

Nrog GI raws li lub hauv paus hlau, tom qab pretreatment (degrease thiab tshuaj kho mob) thiab kua dope nrog ob peb txheej xim, ces tom qab tua thiab txias, thaum kawg lub phaj hlau hu ua pre-painted galvanized steel (PPGI). Pre-painted galvanized steel yog zoo muaj peev xwm kho kom zoo nkauj, molding, corrosion kuj.

Cov ntsiab lus tshuaj:

Zinc yog ib qho tseem ceeb tshaj plaws ntawm cov kab mob hauv cov xim ua ntej galvanized steel coils, thiab nws cov ntsiab lus feem ntau yuav tsum ntau dua lossis sib npaug li 99.5%. Tsis tas li ntawd, cov ntsiab lus ntawm lwm cov kab lus yuav tsum feem ntau nyob rau hauv qhov tsim nyog ntau yam, xws li silicon, hlau, txhuas, tooj liab, thiab lwm yam. Cov ntsiab lus yuav tsum tau tswj xyuas thaum ua kom lub zog thiab corrosion kuj ntawm steel kauj.

Txheej txheem txheej txheem:

1. Cov txheej txheem ua ntej pleev xim rau galvanized steel kauj pib nrog kev ntxuav ntawm galvanized steel substrate. Lub substrate yog ntxuav kom tshem tawm cov av, roj, thiab lwm yam kab mob. Qhov no yog qhov tseem ceeb rau cov xim adhesion rau lub substrate.

2. Tom qab ntxuav, lub substrate yog kho nrog tshuaj tov los txhim kho nws corrosion kuj thiab txhim kho cov xim adhesion. Cov txheej txheem no hu ua chromating. Thaum lub sij hawm chromating, lub substrate yog immersed nyob rau hauv ib tug tov ntawm chromic acid thiab lwm yam tshuaj.

3.Cov kauj ruam tom ntej yog daim ntawv thov txheej primer. Cov txheej primer pab txhim kho cov xim pleev xim rau lub substrate thiab muaj kev tiv thaiv corrosion ntxiv. Lub primer yog siv rau lub substrate siv ib tug roller los yog tshuaj tsuag.

4. Tom qab cov primer, pre-painted galvanized steel coil undergoes ib tug curing txheej txheem. Cov txheej txheem curing tso cai rau cov primer kom qhuav thiab tawv. Cov txheej txheem kho feem ntau yog ua tiav hauv qhov cub tshwj xeeb, thiab lub sijhawm ntev nyob ntawm qhov tshwj xeeb ntawm primer thiab curing kub.

5. Thaum cov primer kho tau lawm, lub topcoat yog siv. Lub topcoat yog txheej kawg ntawm pre-painted galvanized steel kauj. Nws muab kev zoo nkauj tiav thiab muab kev tiv thaiv corrosion ntxiv. Lub topcoat yog siv los ntawm cov menyuam los yog tshuaj tsuag.

6. Tom qab lub topcoat tau thov, pre-painted galvanized steel coil undergoes ib tug zaum kawg curing txheej txheem los harden lub topcoat thiab khi rau primer. Cov txheej txheem curing no tuaj yeem siv sijhawm li ob peb teev, nyob ntawm seb hom txheej thiab qhov curing kub.

Qhov zoo:

1. Cov durability zoo heev: Pre-painted galvanized steel coils paub txog lawv cov durability zoo, uas ua rau lawv muaj kev ntseeg siab rau kev siv mus ntev. Lawv tiv taus corrosion, abrasion, thiab huab cua thiab tuaj yeem tiv taus qhov kub thiab txias ib puag ncig.

2. Kev tu qis: Cov txheej txheem ua ntej pleev xim ntawm cov hlau coils ua rau lawv tsis tshua muaj kev tu. Lawv tsis tas yuav repainting los yog kov-ups thiab tuaj yeem khaws lawv cov tsos rau xyoo tsis muaj fading lossis tev.

3. Tus nqi zoo: Pre-painted galvanized steel coils yog tus nqi qis dua piv rau lwm cov khoom siv hauv tsev xws li txhuas lossis stainless hlau. Lawv muaj ntau yam xim thiab ua tiav uas tuaj yeem ua raws li cov khoom siv kim, xws li ntoo lossis cib, rau ib feem ntawm tus nqi.

4. Ntau yam: Cov hlau coils no tuaj yeem siv rau ntau yam kev siv, nrog rau kev siv vov tsev, phab ntsa cladding, thiab kev lag luam thiab kev tsim kho. Lawv hloov tau yooj yim thiab hloov tau yooj yim, uas ua rau lawv xaiv cov khoom siv zoo tshaj plaws rau kev cai tsim thiab cov qauv tsim vaj tsev.

5. Eco-friendly: Pre-painted galvanized steel coils yog ib puag ncig tus phooj ywg vim lawv yog tsim los ntawm cov khoom siv rov ua dua tshiab. Lawv kuj muaj zog-npaum li lawv tuaj yeem cuam tshuam lub hnub ci, txo lub zog xav tau rau cov cua txias.

Daim ntawv thov:

1. Lub tsev thiab kev tsim kho: PPGI feem ntau siv rau lub tsev thiab kev tsim kho, tshwj xeeb tshaj yog rau lub ru tsev thiab phab ntsa cladding. Nws muab kev tiv thaiv zoo heev tiv thaiv huab cua thiab corrosion, thiab nws lub neej ntev ua rau nws muaj txiaj ntsig zoo rau kev tsim kho.

2. Automotive kev lag luam: PPGI yog dav siv nyob rau hauv kev lag luam automotive los tsim lub cev ntawm lub tsheb, nrog rau cov tsheb, tsheb npav, thiab tsheb thauj khoom. Nws lub zog zoo tshaj plaws thiab kev tiv thaiv corrosion ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv tsheb.

3. Cov khoom siv hluav taws xob: PPGI kuj tau siv dav hauv kev tsim cov khoom siv hluav taws xob xws li tub yees, cua txias, thiab tshuab ntxhua khaub ncaws. Nws durability thiab tsis kam mus rau lwm yam ua rau nws yog ib qho kev xaiv zoo rau cov khoom siv hluav taws xob.

4. Rooj tog thiab kho kom zoo nkauj sab hauv: PPGI yog siv los tsim cov rooj tog zaum, xws li cov txee thiab txee, thiab rau kev kho kom zoo nkauj sab hauv, nrog rau cov phab ntsa thiab qab nthab. Nws txoj kev zoo nkauj thiab kev xaiv xim xim ua rau nws yog cov khoom siv zoo tagnrho rau kev kho kom zoo nkauj sab hauv.

5. Kev lag luam tsheb thauj mus los: PPGI kuj tseem siv rau hauv kev lag luam tsheb thauj mus los rau kev tsim cov ntim khoom, cov tsheb thauj khoom, thiab lwm yam khoom siv thauj mus los. Nws lub teeb-yuag thiab durability ua rau nws nyiam cov khoom siv rau kev thauj mus los.
