Cov Suav Tau Txais Lawv Lub Npe Rau Tabular Corundum

Tabular corundumtau sintered nyob rau hauv ncej kiln invented los ntawm ThomasS.Curis nyob rau hauv 1934 thiab tau ua lag luam nyob rau hauv 1935 tom qab ib tug intermediate xeem raws li ib tug ob peb txheej rau furnaces nyob rau hauv lub refractory thiab ceramic industries. Nyob rau xyoo 1950, raws li cov khoom siv refractory sib sau ua ke, nws tau siv rau hauv kev lag luam refractory. Tom qab ntawd, cov khoom lag luam tabular corundum nrog qis NaO muaj alumina raws li cov khoom siv raw tau tsim ua tiav.

Tabularcorundum yog tam sim no dav paub los ntawm domestic refractory kev lag luam, tab sis nyob rau hauv lub lig 1980s, cov high-end refractory khoom no tsuas yog hu ua Tabularcorundum. Yog li thaum twg Suav lub npe tabular corundum tau los ua thiab vim li cas nws thiaj li muaj npe.

Txog rau thaum xyoo 1990s, Tuam Tshoj Tabular corundum kev lag luam tau monopolized los ntawm cov tuam txhab txawv teb chaws tau ntev thiab lawv tsis tuaj yeem tsim cov khoom siv high-end refractory lawv tus kheej. Yog li ntawd, nws yog ib qho tseem ceeb rau cov tuam txhab lag luam hauv tsev siv lub npe Askiv "Tabularcorundum" thaum importing cov khoom los ntawm txawv teb chaws. Qhov xwm txheej no txuas ntxiv mus txog xyoo 1997, thaum cov kws tshaj lij coj los ntawm Zhang Huiyou tau ua haujlwm tsis tu ncua thiab tom qab ntau txhiab qhov kev tshawb nrhiav, lawv thaum kawg ua tiav hauv kev paub txog kev tua hluav taws ntawm tab-zoo li corundum.

Tabularcorundum yog ib qho ntawm cov khoom siv nyuaj tshaj plaws hauv Suav teb. Txawm li cas los xij, nws tsis yooj yim rau siv lub npe Tabularcorundum ntawm Suav tuam txhab. Peb xav tau lub npe Suav tsim nyog rau cov khoom. Pab pawg kws tshaj lij tuaj nrog cov npe xws li "sintered corundum," "High temperature corundum," "crystalline corundum," thiab txawm tias "flake alumina," tab sis tsis muaj lub npe no feem ntau raug ntes cov txheej txheem tsim khoom thiab cov yam ntxwv ntawm cov khoom tshiab.

"Sintered tabular corundum" npaj los ntawm Mr. Zhang Huiyou, hu ua "tabular corundum", yog qhov nthuav heev. Lo lus "sintered" nyob rau hauv lub npe yog hais txog cov txheej txheem firing ntawm tabular corundum, uas yuav tsum tau alumina npas raug rho tawm haujlwm thiab crystallized ntawm qhov kub ntawm 1700-1900 degrees Celsius. Lo lus "tabular" txhais tau hais tias lub cev thiab tshuaj cov qauv ntawm cov khoom tiav tom qab raug rho tawm haujlwm nthuav tawm lub xeev ntawm kev sib txuas siv lead ua nyob rau hauv lub tshuab tsom. Lo lus "corundum" qhia txog tus kheej ntawm nws cov khoom alumina.
