Hauv cov txheej txheem tsim khoom tiag tiag ntawm cov enamel- cov kab hauv kab, kev siv ntau yam khoom siv raw thiab cov txheej txheem ntau lawm ua rau muaj ntau yam tsis xws luag. Ntawm cov no, qhov tseem ceeb tshaj plaws yog cov hauv qab no:
Cov ntawv hlau yog cov khoom siv tseem ceeb tshaj plaws rau cov enamel-lined liners. Qhov zoo ntawm cov ntawv hlau yuav tsum raug xaiv raws li kev tsim (deformation, vuam, thiab lwm yam), cov txheej txheem enameling, thiab cov kev cai ntawm cov khoom enamel.
Lub xub ntiag ntawm manganese nyob rau hauv steel tsub kom nws yield zog thiab qhov kawg tensile zog, tab sis txo nws elongation. Yog li, qhov siab dua cov ntsiab lus ntawm manganese, qhov ntau dua qhov xav tau deformation quab yuam. Rau carbon steel, silicon thiab manganese yog ob qho tib si seem ntawm deoxidizers los ntawm smelting. Cov ntawv hlau uas muaj cov ntsiab lus silicon qis dua 0.37% feem ntau tuaj yeem sib sib zog nqus- kos, tab sis dhau qhov nqi no, txawm tias cov hlau tsis tshua muaj cov ntsiab lus carbon tsawg, yuav dhau los ua tawv thiab tawv, tsis haum rau kev sib sib zog nqus nqus, thiab yuav cuam tshuam rau adhesion.
Lub xub ntiag ntawm sulfides cuam tshuam rau microstructure ntawm cov ntawv hlau, txhawb kev tsim cov striations, yog li txo cov hlau plasticity thiab toughness, piv txwv li, txo qhov sib sib zog nqus- kos duab kev ua tau zoo, thiab ua rau npuas thiab pores nyob rau hauv lub enamel txheej. Phosphorus yaj nyob rau hauv ferrite ho txo cov yas ntawm hlau thaum nce nws lub zog thiab hardness. Cov ntsiab lus phosphorus hauv daim hlau siv rau kev sib sib zog nqus nqus yuav tsum tsawg li tsawg tau (<0.06%). Adding titanium to steel is highly beneficial for enamel, as it can combine with various components in the enamel, thus increasing adhesion. For one-time enamel coating of the water heater inner tank (wet flow enamel, wet spray enamel, electrostatic powder spray enamel), titanium steel is a relatively ideal base material.
Aluminium-muaj cov hlau tuaj yeem nruam txuas ntxiv, muaj kev sib cais tsawg dua thiab kev suav nrog, muaj peev xwm ua haujlwm txias, thiab tiv taus kev laus. Nws qhov teeb meem loj tshaj plaws yog tias nws nquag ntses - nplai qhov tsis xws luag tom qab enamel tua thiab txo cov adhesion zog. Lub thickness ntawm cov khoom siv phaj yuav tsum raug xaiv kom ntau li ntau tau los xyuas kom meej txaus thickness ntawm lub tank sab hauv. Tsuas yog los ntawm kev xaiv qib siab - cov hlau nplaum zoo tuaj yeem lav qhov zoo ntawm lub tank sab hauv, yog li ua kom muaj kev pabcuam lub neej ntawm lub tank sab hauv.
