Lub ntsiab zoo ntawm ua ntaub ntawv thov lub cev abrasive lub cev muaj raws li nram no:
(1) txuag hluav taws xob: txo lub peev xwm kev thauj khoom ntawm kev sib tsoo lub cev ntawm zeb los ntawm 20%, txo qhov tam sim no ntawm lub tshuab tseem ceeb los ntawm ntau dua li 20%, thiab txuag hluav taws xob los ntawm ntau dua li 1 5% rau tons ntawm cement;
(2) kev txhim kho kom zoo: txhim kho qhov kev ua tau zoo ntawm cov khoom siv cement, thiab cov particle muaj pes tsawg leeg tsim nyog dua. Cov ntsiab lus ntawm 3-3 2 m 2 cov xeb nce ntxiv los ntawm ntau dua li 2%, cov dej thooj kheej ntxiv nce ntxiv, kev noj haus dej rau cov qauv kev sib txig txo los ntawm 1% ~ { {0}}%, thiab qhov sib xyaw ntawm cov khoom siv cement thiab pob zeb ua kev ntxiv.
(3) kom tsis txhob muaj cua txias thiab suab nrov: qhov ntsuas kub sab hauv ntawm lub zeb yog txo los ntawm ntau dua li 15 ℃, thiab lub suab nrov ntawm lub zeb raug txo los ntawm ntau dua li 15 dB;
(4) hnav tsis kam: kev noj tawm ntawm cov pob txhaws pob zeb yog feem ntau 50% ntawm cov pob steel, xws li kev ua haujlwm ntawm 4 2.. 5 Portland zoo tib yam, siab chromium steel pob npas noj ntawm 30 ~ 4 0g / t, thiab microcrystalline high-strength alumina pob yog ≤ 15 g / t;
(5) kev tiv thaiv ib puag ncig: txo cov pa phem hnyav yog qhov muaj txiaj ntsig zoo rau kev ua tiav ntawm lub teb chaws tus qauv rau cov ntsiab lus ntawm dej-soluble hexavalent chromium hauv cov khoom lag luam (≤ 10 mg / kg).
Dab tsi yog cov yam ntxwv ntawm cov yam ntxwv tseem ceeb ntawm kev siv pob alumina ceramic pob?
Lub hauv paus tshuaj lom neeg tseem ceeb ntawm alumina ceramic pob yog Al 2 O 3, teev rau 9 2%, ntxiv rau, muaj 8% hloov kho cov ntaub ntawv hnyav xws li zirconia. Nws cov txheej txheem molding feem ntau muab faib ua ob pawg: nias molding thiab dov molding, txhua yam ntawm cov ntsiab lus tshwj xeeb, txoj kab uas hla tsawg dua 2 0mm siv dov molding, txoj kab uas hla ntau tshaj 2 0 hli siv nias molding.
Dab tsi yog lub cev lub zog ntawm alumina ceramic pob?
Mohs hardness ntawm alumina ceramic pob yog 9. 0, rockwell hardness yog {{{{8 {}}} ~ ~ {{3}} Lub ntom ntom yog 3. {{5 }} g / cm 3, thiab qhov ntau ntau yog 2. 2 t / m 3 .Nws yog cov pob zeb khoom pob zeb tshwj xeeb uas tsim los rau kev sib tsoo pob zeb qhuav. Los ntawm kev ntxiv zirconia rau toughen lub pob ceramic, cov pob zeb ceramic tsis yog tsuas yog ntawm lub zog siab, tab sis kuj ntawm zoo toughness.
Txoj kev kho cov txheej txheem twg yog cov pob zeb pob khoom haum rau cov pob zeb sib tsoo pob zeb?
Cov pob zeb (Ceramic pob) yog qhov tsim nyog rau ntau yam txheej txheem ntawm cov pob zeb qhuav kawg sib tsoo pob zeb pob zeb kaw lus, tshwj xeeb tshaj yog kev sib tsoo txheej txheem ntawm cov hlau zeb thiab pob zeb pob. Nws yog qhov yuav tsum tau hais tias qhov nruab nrab qhov loj me ntawm qhov sib tsoo cov khoom siv yog tsawg dua li 1 mm.Other cov hmoov av sib tsoo qhib lossis kaw cov txheej txheem ntawm lub pob zeb sib tsoo rau hauv (kawg rau hauv), tuaj yeem siv cov pob zeb siv pob dua siv steel pob (steel forging).
