Enamel

Enamel,raws li ib tug ntev-sawv nto kho kom zoo nkauj thiab tiv thaiv cov khoom, yog dav siv nyob rau hauv industrial ntau lawm thiab lub neej txhua hnub.Nws tsis yog tsuas yog zoo nkauj thiab ruaj khov, tab sis kuj muaj tshuaj lom neeg ruaj khov thiab corrosion kuj.Los ntawm qhov kev xav ntawm kev tsim khoom, kev tsim cov txheej txheem ntawm cov enamel yog cov txheej txheem nyuaj uas ua ke nrog cov ntaub ntawv tshawb fawb, tshuaj lom neeg engineering, thiab kev siv thev naus laus zis zoo, suav nrog kev xaiv raw khoom, npaj, txheej, thiab tua hluav taws.

1. Txhais thiab muaj pes tsawg leeg ntawm enamel

Enamel yog cov khoom sib xyaw tsim los ntawm melting inorganic glassy cov ntaub ntawv mus rau cov hlau matrix thiab sintering lawv ntawm qhov kub thiab txias.Cov khoom tseem ceeb muaj xws li glaze (silicate, borate, thiab lwm yam), cov xim, fluxes, thiab cov khoom siv ntxiv.Ntawm lawv, glaze yog lub hauv paus rau kev tsim cov txheej txheej enamel, uas txiav txim siab lub cev thiab tshuaj lom neeg ntawm enamel;Colorants yog siv los sib tov xim;Flux pab lub glaze ntws thaum lub sij hawm firing txheej txheem, kom ntseeg tau ib tug du glaze nto;Enhancers txhim khu lub zog txhua yam thiab adhesion ntawm txheej.

2. Kev npaj cov khoom siv raw

Thawj kauj ruam hauv kev tsim cov enamel yog xaiv thiab pretreatment ntawm raw cov ntaub ntawv.Cov hlau substrate feem ntau yog ua los ntawm hlau, hlau, txhuas, thiab lwm yam, thiab cov khoom tsim nyog thiab tuab yuav tsum raug xaiv raws li daim ntawv thov.Kev npaj ntawm glaze yuav tsum sib tov ntau yam raw cov ntaub ntawv nyob rau hauv kev faib ua feem, sib tsoo lawv mus rau ib tug tej degree ntawm fineness, los xyuas kom meej lub uniformity thiab zoo ntawm txheej txheej kawg.Nyob rau theem no, nruj raw khoom kuaj yuav tsum tau xyuas kom meej tias tsis muaj impurities, thiaj li tsis cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm enamel txheej.

3. Kev kho deg

Ua ntej txheej txheej, cov hlau substrate yuav tsum tau ntxuav thiab kho qhov chaw kom tshem tawm cov roj, oxide daim tawv nqaij, thiab lwm yam kuab paug.Cov txheej txheem muaj xws li degreasing, kua qaub ntxuav, phosphating, thiab lwm yam. Cov kauj ruam no yog qhov tseem ceeb rau kev txhim kho lub zog sib txuas ntawm cov enamel txheej thiab cov hlau substrate.

4. txheej txheem Enamelling

Cov txheej txheem txheej tuaj yeem muab faib ua ob pawg: txoj kev qhuav thiab txoj kev ntub dej.Cov txheej txheem qhuav feem ntau suav nrog electrostatic hmoov txau thiab fluidized txaj immersion txheej, uas yog tsim rau loj-scale automated ntau lawm, muaj peev xwm tswj tau zoo txheej thickness, thiab yog ib puag ncig tus phooj ywg.Cov txheej txheem ntub dej muaj xws li yob txheej, dip txheej, thiab cov tshuaj tsuag txheej, uas yog tsim rau cov duab nyuaj thiab cov khoom me me, tab sis nws muaj kev ua qias tuaj ib puag ncig thiab cov teeb meem tsis sib xws.

5. Kub

Cov khoom siv coated yuav tsum raug rho tawm ntawm qhov kub thiab txias, uas yog ib qho tseem ceeb hauv kev tsim cov txheej txheej zoo enamel.Qhov kub ntawm qhov hluav taws kub yog feem ntau ntawm 800 ° C thiab 900 ° C, nyob ntawm seb hom glaze thiab substrate hom.Thaum lub sij hawm firing txheej txheem, lub glaze melts thiab tusyees npog cov hlau nto.Tom qab txias, nws tsim ib qho nyuaj thiab du enamel txheej.Cov txheej txheem no tseem yuav tsum muaj kev tswj xyuas nruj ntawm cov cua sov, lub sij hawm rwb thaiv tsev, thiab qhov cua txias kom tiv thaiv qhov tshwm sim ntawm qhov tsis xws luag xws li tawg thiab npuas.

6. Kev tshuaj xyuas zoo thiab kev ua haujlwm tom qab

Tom qab tua hluav taws, cov khoom enamel yuav tsum tau soj ntsuam nruj nruj, nrog rau kev soj ntsuam zoo li qub, kev kuaj corrosion kuj, kev kuaj xyuas lub zog, thiab lwm yam. Cov khoom tsis tsim nyog yuav tsum tau kho lossis muab pov tseg.Tsis tas li ntawd, nyob ntawm cov khoom siv, cov kauj ruam ntxiv xws li kev sib dhos thiab ntim yuav tsum tau ua.

7. Daim ntawv thov teb

Enamel tau siv dav hauv ntau lub teb vim nws qhov kev ua tau zoo heev.Hauv kev lag luam khoom siv hauv tsev, xws li qhov cub, tshuab ntxhua khaub ncaws, lub tshuab rhaub dej, thiab lwm yam, cov enamel liner tsis yog tsuas yog ua kom zoo nkauj thiab yooj yim los ntxuav, tab sis kuj tiv taus kub thiab corrosion.Hauv kev kho kom zoo nkauj vaj tsev, enamel steel daim hlau feem ntau yog siv rau sab nrauv phab ntsa, tunnels, subway chaw nres tsheb, thiab lwm yam vim lawv cov xim nplua nuj thiab muaj zog tiv thaiv huab cua.Tsis tas li ntawd, cov cuab yeej siv kho mob, cov cuab yeej siv tshuaj thiab lwm yam kev lag luam kuj tseem siv cov khoom siv enamel, ua kom zoo dua ntawm lawv cov tshuaj lom neeg ruaj khov thiab cov yam ntxwv yooj yim tua kab mob.

Xaus

Zuag qhia tag nrho, kev tsim cov enamel kev lag luam yog cov txheej txheem nyuaj uas sib xyaw cov txheej txheem ib txwm siv nrog cov thev naus laus zis niaj hnub.Nws cov khoom tiav tsis tsuas yog qhia txog kev sib xyaw ua ke zoo tshaj plaws ntawm kev zoo nkauj thiab kev ua tau zoo, tab sis kuj tseem cuam tshuam txog kev nce qib ntawm cov khoom siv science thiab kev tsim technology.Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, cov khoom lag luam enamel tau txav mus rau ib puag ncig tus phooj ywg ntau dua, muaj txiaj ntsig zoo, thiab kev coj ua ntau yam, tsis tu ncua raws li cov kev xav tau ntawm ntau qhov chaw.

Txhua qhov kev nug rau Casting, Forging lossis Machining qhov chaw, thov koj xav tiv tauj peb txhua lub sijhawm.
