Tiv tauj peb

Peb cov khiav hauj lwm rau tej hub frit tau ntau xyoo thiab peb muaj kev nplua nuj nyob hauv daim teb no kom koj zoo. Yog koj xav siv hauv cov khoom peb, qhia txog koj require (li firing kub, nws lub sij hawm thiab glaze nyhuv) tsis muaj hesitation. Peb yuav muab pub dawb xwb cov qauv rau kev tshuaj ntsuam koj. Kuj Engineers muaj nyob rau qhov kev pab cov neeg tuaj txawv tebchaw.

Tus thoob ntiaj teb kom muab kev koom tes nrog peb caw ua tsaug!

Frit ntau lawm thiab tswj txoj kev

Zibo Jinming Glaze Co., Ltd | Updated: Mar 24, 2016

1. firing Frits, hmoov mixtures li cua sov ntsuam cov kev hloov hauv qab no: yog cov dej uas muaj nyob hauv cov ntaub ntawv raw evaporation thiab ces thiaj tso dej siv lead ua, xws li borax, txawm raising kub emit dej tshuaj, xws li boric acid. Decomposed khoom rau hauv oxides. Thaum tseem yog cov kub sawv, yaj yam khoom uas nyob rau hauv cov hmoov tsis pib kom yaj, clear molten yog vim lub xeev hais kom cov melting nyhuv, uas qhia nyoos hmoov sintering phenomena, cov ntaub ntawv tau thiab uas softened los yog melted ntaub glued ua ke thiab maj melting. Muaj peevxwm mus txuas ntxiv kom sawv, alkaline thiab acidic oxides INTERACTIONS rau daim ntawv silicic acid. Tsis tas yuav txhim ib tug yooj yim Portland, kuj muaj ntau nyob rau ntawm frit daim ntawv "eutectic". "Ib tag nrho yaj" yog ua los ntawm ib co mixtures tshaj nws lub taw tes melting ntawm ob pawg monomers muaj ib ntau sab melting point. Melting cheej nyob ntawm feldspar ntshiab si qho 1280 thaum tov CaO 9:1, lub melting point xwb 1210 c. Refractory CaO thiab SiO2 calcium uas silicate, calcium uas silicate, tag nrho yog ib fusible khoom tawg yooj yim, nws yog zoo li lub melting ntawm feldspar. Lwm yam yooj yim oxides kuj ua coj kev hloov hauv tus txheej txheem, xws li: K2O, thiab Na2O, thiab MgO, thiab ZnO. Portland uas muaj ntau no, los yog solidifying cov hav zoov nyob rau hauv lub molten pawg twg Portland, nyob rau frit muaj pes tsawg leeg, mas vim nws tsi muaj lub luag hauj lwm txawv ntawm ib yam khoom uas, tiam sis ntiav rau tag nrho cov kev kawm ntawv, lawv muaj pes tsawg leeg yog xwb uas muaj tuaj raws ntau oxides nyob rau hauv kev faib ua feem sib. Oxidation thiab decomposition, thiab thaum lawv tseem piav los saum no yog ua thaum txoj kev cua kub, kom zoo li siab tau nyob hauv lub oxidation txheej txheem, combining theem Portland ntau ua rau tag nrho nws yuav zoo dua, kom koj tau zoo zoo frit. Tab sis nyob hauv cov txoos zus tau tej cov frit rau zoo, nrog frit rauv qauv, yam roj, qhov kub thiab txias, cua thiab txoj kev zov me nyuam ntawm nplaim ua ib txoj kev sib raug zoo, tsa ntawm tus frit frit cua sov ntawm cov ntaub ntawv saum toj no muaj ib co weaknesses. Conical Crucible rauv, hmoov ntawm lub sab sauv pub ntxiv tshaj, yaj txaus los rau nram qab, preheating, oxidation, compounding yaj yog zoo tagnrho, tiam sis feem ntau vim yog qhov zoo heev, sov tsis raws li txojcai, melting tsis tiav lawm, zoo nkaus li ntes tau frit nyoos tej yam zoo. Dua plus Crucible siv lub neej luv, los ntau lawm theem yuav tsum uas yooj yim; nram qab converter them los yog hauj lwm sib quas ntus, txhob pub kom melting zoo, saum ntuj ua tau los tsis kub los kub ntawm cov txheej txheem, rau oxidation decomposition, melting favourable ntawm no, tab sis vim melting lub sij hawm ntev, yaj uas tsis muaj khoom tawg yooj yim ntawm cov neeg tsis mloog hais yog inevitable uas sib ntxiv zog noj ntshav, pub Shi hmoov phem kuj overcome; pas dej ua ke zoo li tus cua sov npe ntau xwb, vim nws ntim me me, hmoov clear melting tsiv dhau rau oxidation decomposition Vaccine adverse. Tej hmoov los hauv lub xeev molten, nws twb tsis tau mus txog nrog cov yaj tsawg, los ntawm tsis tiav melting, lub cub tawg saab nrau siab zog noj, uas tsis muaj cov neeg tsis mloog hais soluble yam khoom uas muaj ntau heev, cov neeg tsis mloog hais li cov roj flue nris, nqa ib co teeb meem rau qhov kho dua.

2. yaj kub kub ncaj qha mus txog rau glaze viscosity, pib melting kub thiab cov glaze firing ntau yam. Vim lub cub tawg Frits me me, ntim kub loj fluctuations, feem ntau yuav ua instability nyob molten pawg, li no melting kub tswj thaiv tsis tau ignored. Txawv ntawm yaj thaiv Kex muaj ntau ntawm melting kub, kev fluctuations nyob 1250 ~ 1350℃ Zhijian, kub txog seb loj raws li glaze deg zoo, tsis hais leej twg daim ntawv thov li cas kiln rauv glaze hlawv, yog vam cia firing khwv dav glaze khoom, los kiln txais cua sov Shang, thiab kub Xia thiab firing hauv qhov uas kub thiab txias fluctuations, tshwj xeeb tshaj yog nrov suab yau yau yam qhov kiln yog relies rau nrov suab yau yau Board ntawm tshav kub xav yuav firing ntawm , nws Shang, thiab Xia kub nyob mus li ntshav li kub mesophile firing khwv uas nqaim ntawm glaze ntaub yog tsis txais, ces yuav tsum hlawv glaze ntau yam ib yam li 60 ℃. Frit kev sib raug zoo ntawm lub melting kub thiab tus viscosity ntawm cov glaze nyob ze heev thaum Frits melting kub ntawm 1420 thaum lub glaze ntws kom txog hos 43 tus hli, thaum cov txias sov tuaj poob hauv qab lub 1320 c , ntws ntev hli 67. Qhov no proves uas: kub, viscosity siab, tsis kub, uas tsis muaj viscosity. Raws li Frits melting kub, pib melting nrog rau kev hloov hauv qhov kub thiab txias thaum melting 1260 ° c, melting 915 kub kub thiab txias. Thaum cov kub ntau zog rau 1280 c, pib melting kub yog 945. Viscosity glaze thiab glaze firing ntau yam muaj roj. Glazed zog, tsis pub pinhole, corrugated thiab lwm yam los tsis xws luag. Viscosity kub glaze frit, analyzed vim li cas tseem ceeb: yam tsawg kawg melting hloov los ntawm melting blocks ntev li ntawm neeg tsis mloog hais. Raws li qhov tus xeeb ceem, sawv los txo lub melting kub hloov lub viscosity ntawm cov glaze. Glaze firing ntau yog tsis muaj cua sov tsis tsim sab sauv thiab sab thaum qhov kub qhov txawv, tej zaum yuav tau txo tus kub melting, yuav tsum txhim khu glaze pib melting kub, ua kom cov yaj kub yuav tiav tau. Yeej tsis unprincipled yuav nce los yog txo cov kub, kom zoo frit ua ib precondition. Xav kom zoo frit, yuav tsum tau muaj rau lub sij hawm, quantitative noj los ntawm lub caij xeem thiab sau rau qhov kub thiab txias. Nplaim cua tseem muaj ib co cawv rau clinker zoo thiab yuav tsum muab sau rau hauv oxidizing cua sintering, tsis txhob txo nplaim taws hlawv hauv lub cub tawg, Ikenouchi siab zoo yuav tsum tsis tau loj heev, cuam tshuam tsis zoo tiv thaiv kev txo hlau oxide.
