Hnub no, muaj ntau yam khoom tiav ntawm kev ua lag luam uas tshwj xeeb "hnub nyoog" txhawm rau kom tau txais cov txiaj ntsig zoo nkauj. Chamotte av nplaum yog ib qho ntawm lawv. Nws muaj cov khoom yas tshwj xeeb, muaj ntau yam kev siv, thiab tau dhau los ua neeg nyiam thoob plaws ntiaj teb.
Chamotte yog hom av nplaum, cov khoom siv ceramic, cov khoom sib xyaw refractory uas tsim los siv cov cuab yeej tshwj xeeb. Qhov no yog ib qho tshiab (tsim nyob rau hauv lub xyoo pua XIX), tab sis twb nrov heev natural khoom. Cov khoom los ntawm nws nyob rau hauv lawv cov qauv thiab xim zoo li ib tug qub pob zeb, nyob rau hauv uas cov kab nrib pleb thiab chips yog pom. Qhov saum npoo yog beige, ntxhib, qab ntxiag rau qhov kov. Fireclay khoom haum txig rau sab hauv nrog cov rooj tog ntoo.
Tsev tsim khoom
txheej txheem ntawm kev ua cov fireclay muaj cov kauj ruam hauv qab no:
1. Kev yuav cov khoom siv raw - av nplaum tuaj rau hauv daim los yog nias briquettes.
2. Roasting - tshwm sim nyob rau hauv ncej, rotary kilns ntawm qhov kub ntawm tsawg kawg yog 1200 ° C. Kev nqus dej ntawm hluav taws kub chamotte yog nyob rau hauvnruab nrab ntawm ob thiab kaum feem pua.
3. Sib tsoo - raug rho tawm haujlwm chamotte yog hauv av rau cov hmoov daim ntawv ntawm qhov yuav tsum tau granularity nyob rau hauv mills. Qhov nruab nrab qhov chaw tshwj xeeb yog 8000 cm / g.
Lub luag haujlwm tseem ceeb ntawm cov txheej txheem thev naus laus zis:
- tua kom txog thaum plasticity ploj lawm;
- tshem tawm cov tshuaj tiv thaiv dej.
Chamotte av nplaum - khoom
Qhov nrov ntawm chamotte muaj feem xyuam nrog nws cov khoom, cov no yog:
- txhua yam muaj zog;
- tsis ntsws;
- zoo heev;
- ib puag ncig tus phooj ywg - khoom siv huv huv;
- hluav taws kub, kub ua haujlwm, kub ua haujlwm;
- tsis ntshai dej, tsis muaj dej;
- Frost resistance;
- profitability.
Scope of application
Cov av nplaum uas tau txais chamotte yog siv los ua cov khoom siv hauv tsev, av nplaum. Qhov no txo cov plasticity thiab shrinkage ntawm cov khoom thaum ziab thiab tua. Piv txwv li, qhov sib ntxiv ntawm fireclay ua rau nws tuaj yeem ua cov duab puab uas hnyav tshaj 250 kg. Kev siv cov khoom siv no pab qhia txog lub sijhawm qub qub, kos duab Greek thaum ub, Japanese motifs, cov ntsiab lus ntawm kev kos duab thaum ub. Hauv Tebchaws Europe, chamotte av nplaum yog siv rau cladding facades, qhov cub, thiab phab ntsa. Hauv kev lag luam, cib refractory, ntau yam khoom siv hluav taws xob, thiab ceramics yog tsim los ntawm cov av nplaum.
Ntau lub tuam txhab muab cov pobzeb hluav taws sib sau ua ke. Nws sab ntxhib zoo kawg nkaus du, thiab cov nyhuv chipped,scuffs, jagged npoo yog tsim tsuas yog ntawm qhov pom. Qhov ntau pronounced heterogeneity thiab curvilinearity, qhov kim dua li cov pobzeb yog.
Chamotte av nplaum qhia txog qhov ntuj tsim, thiab qhov no yog qhov uas txhua tus tsis muaj nyob hauv lub ntiaj teb niaj hnub no. Yog li ntawd, cov khoom tsim los ntawm nws yuav ib txwm nyob rau hauv kev thov, txawm nyob rau hauv fashionable renovation thiab du nto. Chamotte tau txais kev nyiam sai sai thoob plaws ntiaj teb raws li cov khoom siv kho kom zoo nkauj rau kev tsim vaj tsev. Nws cov khoom yog lub sijhawm sim, yog li peb tuaj yeem hais nrog kev ntseeg siab tias qhov no yog cov khoom siv zoo thiab txhim khu kev qha. Chamotte yog lub zoo meej "tsis xws luag" hauv ceramics.
