Alumina Sib tsoo Media Pob

Feem ntau, cov uas muaj alumina cov ntsiab lus ntawm 60% mus rau 65% yog cais raws li nruab nrab txhuas cov khoom, cov uas muaj alumina cov ntsiab lus ntawm 75% mus rau 80% raws li nruab nrab-siab aluminium pob, thiab cov uas muaj alumina cov ntsiab lus ntawm 90% los yog ntau tshaj li high aluminium pob. . Ntawm cov no, cov pob alumina siab tau muab faib ua 90 plooj (porcelain), 92 plooj (porcelain), 95 plooj (porcelain), 99 plooj (porcelain). Vim tias tus nqi tsim khoom ntawm 99 plooj (porcelain) yog qhov siab heev, nws tsis tshua muaj cov khoom loj los ntawm cov tuam txhab loj, thiab tam sim no nws yog xuas tes ua hauv qee qhov tshwj xeeb ceramic factories. Ceramic sib tsoo xov xwm tam sim no nyob rau hauv kev ua lag luam feem ntau suav nrog alumina, zirconia, silicon carbide, silicon nitride thiab lwm yam. Alumina sib tsoo tawm pob yog ib qho tseem ceeb engineering ceramic thiab yog cov khoom siv high-tech. Vim yog cov yam ntxwv ntawm qhov tsim nyog hardness, nruab nrab ntom ntom, hnav tsis kam, corrosion kuj thiab qhov teeb meem ntawm cov hlau impurities nkag mus rau hauv cov khoom hlau, alumina sib tsoo cov khoom siv dav siv hauv cov cement dawb, minerals, ceramics, electronics, hlau nplaum. Nws yog qhov zoo tshaj plaws kev sib tsoo nruab nrab rau kev sib tsoo thiab ua cov ntaub ntawv raw hauv txheej, xim thiab lwm yam lag luam. Nyob rau hauv kev tsim kho ceramics kev lag luam, hnav efficiency ntawm alumina sib tsoo xov xwm pob yog 20% ​​mus rau 40% siab dua li ntawm ntuj flint thiab cobblestones. Nrog kev txo qis ntawm cov khoom siv pob zeb zoo tshaj plaws thiab cov khoom siv siab ntawm cov pob zeb zoo tib yam, alumina ceramic pob yuav siv los ntawm ntau thiab ntau cov tuam txhab ceramic.

Alumina sib tsoo cov khoom siv dav siv hauv ntau qhov kev lag luam, suav nrog tab sis tsis txwv rau cov hauv qab no:

Ua ntej, kev lag luam petrochemical: siv los ua cov khoom siv los yog kev txhawb nqa hauv cov tshuaj reactors los txhim kho cov tshuaj tiv thaiv thiab txo cov corrosion.

Thib ob, hluav taws xob thiab hluav taws xob: siv rau kev tiv thaiv, rwb thaiv tsev kub thiab cua sov dissipation ntawm cov khoom siv hluav taws xob, xws li ntim cov khoom siv semiconductor thiab kev tsim hluav taws xob.

Thib peb, kev tiv thaiv ib puag ncig engineering: siv los ua cov khoom siv hauv cov khoom siv roj cua kom nqus cov pa phem thiab cov teeb meem.

Plaub, hmoov ua: siv rau pob milling, sib tov thiab dispersing ntau yam ntaub ntawv hmoov.

Thib tsib, roj catalyst: Raws li cov cab kuj catalyst, nws yog siv rau ntau yam roj theem catalytic.

Lub ntsiab tseem ceeb ntawm alumina sib tsoo cov khoom siv yog cov khoom siv zoo alumina, uas muaj cov xim dawb thiab tsis cuam tshuam qhov zoo ntawm cov khoom sib tsoo. Thiab nws muaj siab hardness. Nws Rockwell hardness yog HRA80-90, thib ob tsuas yog pob zeb diamond thiab tshaj hnav-resistant hlau. Thib ob, nws siv isostatic nias thiab dov txoj kev, uas muaj lub ntiajteb txawj nqus loj, zoo heev txhim kho kev sib tsoo efficiency, txo lub sij hawm sib tsoo, thiab ua kom muaj txiaj ntsig zoo ntawm lub pob zeb, yog li nce cov khoom sib tsoo. Alumina sib tsoo tawm pob muaj qhov hnav tsis zoo, lawv hnav tsis kam yog sib npaug rau 266 npaug ntawm cov hlau manganese, thiab lawv hnav tsis tshua muaj. Piv nrog steel sib tsoo xov xwm, lawv tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm lub cev sib tsoo ntau dua 10 zaug. Nws tuaj yeem tiv taus qhov kub thiab txias ntau dua 1, 000 degrees thiab yog acid, alkali thiab corrosion resistant.
