Xov xwm

Txhawm rau siv tag nrho cov khoom, ib tus yuav tsum xub nkag siab zoo txog nws, thiab cov xim coated yob tsis muaj qhov tshwj xeeb. Tom ntej no, cia peb qhia peb tus kheej rau cov xim coated yob.
Ua ntej, peb yuav tsum paub tias cov xim coated board yog dab tsi?

Cov xim coated steel sawb siv kub-dip galvanized steel sawb raws li cov substrate tsis tsuas yog muaj zinc txheej rau kev tiv thaiv, tab sis kuj muaj cov organic txheej ntawm zinc txheej rau kev tiv thaiv thiab kev tiv thaiv, tiv thaiv cov hlau sawb los ntawm xeb. Nws lub neej kev pabcuam yog kwv yees li 1.5 npaug ntev dua li ntawm galvanized steel sawb. Qhov thib ob, peb yuav tsum xub to taub lub hom phiaj ntawm cov xim coated yob? Cov xim coated yob yog lub teeb yuag, ua kom zoo nkauj, thiab muaj kev tiv thaiv corrosion zoo. Lawv tuaj yeem ua tiav ncaj qha thiab feem ntau muaj nyob rau hauv ntxoov grey dawb, hiav txwv xiav, thiab cib liab. Lawv tsuas yog siv rau hauv kev tshaj tawm, kev tsim kho, khoom siv hauv tsev, rooj tog zaum, thiab kev lag luam tsheb thauj mus los.
Cov txheej siv rau cov xim coated yob yuav tsum xaiv cov resins uas tsim nyog raws li qhov sib txawv ntawm kev siv ib puag ncig, xws li polyester silicon hloov polyester, polyvinyl chloride yas sol, polyvinylidene chloride, thiab lwm yam. Cov neeg siv tuaj yeem xaiv raws li lawv xav siv. Tom ntej no, koj yuav tsum paub cov txheej txheem txheej:
V txheej qauv hom
2/1: Siv ob zaug rau saum npoo, ib zaug rau ntawm qhov chaw qis, thiab ci ob zaug.
2/1M: Thov ob zaug rau saum thiab sab saum toj, thiab ci ib zaug.
2/2: Siv ob zaug rau saum thiab hauv qab, thiab ci ob zaug.
Kev siv ntau txheej txheej txheej:
2/1: Qhov kev tiv thaiv corrosion thiab khawb tsis kam ntawm ib txheej txheej rov qab yog cov neeg pluag, tab sis nws muaj qhov zoo adhesion thiab feem ntau yog siv hauv sandwich panels;
2/1M: Cov xim rov qab muaj qhov zoo tiv thaiv corrosion, khawb tsis kam, thiab ua cov qauv tsim, nrog kev ua kom zoo, haum rau ib txheej txheej profiled panels thiab sandwich panels.
2/2: Ob txheej txheej rov qab xim muaj qhov zoo tiv thaiv corrosion, khawb tsis kam, thiab ua cov txheej txheem, thiab feem ntau yog siv rau ib txheej txheej profiled panels. Txawm li cas los xij, nws qhov adhesion tsis zoo thiab nws tsis haum rau sandwich panels.

Dab tsi yog qhov kev faib tawm ntawm cov xim coated substrates?
Kub dip galvanized substrate
Cov khoom tau txais los ntawm kev siv cov organic txheej ntawm kub-dip galvanized steel ntawv yog kub-dip galvanized xim coated ntawv. Kub dip galvanized xim coated ntawv tsis tsuas yog muaj kev tiv thaiv ntawm zinc, tab sis cov organic txheej ntawm qhov chaw kuj ua lub luag haujlwm hauv kev tiv thaiv kev tiv thaiv xeb thiab tiv thaiv xeb, nrog lub neej kev pab ntev dua li cov ntawv kub-dip galvanized. Cov ntsiab lus zinc ntawm kub-dip galvanized substrates feem ntau yog 180g / m2 (ob tog), thiab cov ntsiab lus zinc siab ntawm kub-dip galvanized substrates rau kev siv sab nraud hauv tsev yog 275g / m2.
Kub dip aluminium zinc substrate
Kub dip aluminium zinc steel phaj (55% Al Zn) yog siv los ua cov txheej txheej tshiab, feem ntau nrog cov zinc zinc cov ntsiab lus ntawm 150g / ㎡ (ob sab). Kev tiv thaiv ntawm kub-dip aluminium zinc ntawv yog 2-5 npaug ntawm cov ntawv kub-dip galvanized. Kev siv tsis tu ncua lossis sib cuam tshuam ntawm qhov kub txog li 490 ℃ yuav tsis ua rau oxidation hnyav lossis tsim cov nplai oxide. Lub peev xwm los cuam tshuam cov cua sov thiab lub teeb yog ob zaug ntawm kub-dip galvanized steel phaj, thiab ib qho kev cuam tshuam ntau dua 0.75 yog ib qho khoom siv zoo tshaj plaws rau kev txuag hluav taws xob.
Electroplated galvanized substrate
Cov khoom tau txais los ntawm kev siv cov ntawv electroplated galvanized ua cov substrate thiab ci nrog cov organic txheej yog electroplated galvanized xim coated ntawv. Vim yog cov zinc txheej nyias ntawm cov ntawv electroplated galvanized, cov ntsiab lus zinc feem ntau yog 20/20g / m2, yog li cov khoom no tsis haum rau siv sab nraum zoov hauv kev tsim cov phab ntsa, ru tsev, thiab lwm yam. Tab sis vim nws zoo nkauj tsos thiab kev ua tau zoo, nws tuaj yeem siv tau rau cov khoom siv hauv tsev, suab tshuab, steel rooj tog, kho kom zoo nkauj sab hauv tsev, thiab lwm yam. Thaum hnov ​​​​qhov no, koj puas muaj kev paub txog xim coated yob? Yog tias koj txaus siab, tuaj nrog peb tham!
