Q1: Dab tsi yog kev faib tawm ntawm alumina raj?
A1: Lub hom phiaj kev faib tawm:
Chemical pipelines: siv los thauj cov kua qaub thiab alkaline, corrosive media, thiab lwm yam.
Fais fab insulated kav: siv rau rwb thaiv tsev tiv thaiv ntawm cov xov hlau thiab cables.
Ceramic kiln kav: siv rau kiln flue gas emissions, khoom thauj, thiab lwm yam.
Shape classification:
Round yeeb nkab: Ib hom yeeb nkab zoo siv rau kev thauj mus los ntawm cov kua dej.
Square yeeb nkab: siv rau lub sijhawm tshwj xeeb, xws li cov kav dej ruaj khov, cov kav dej sib txuas, thiab lwm yam.
Kev npaj txheej txheem faib:
Sintered alumina raj: Nws yog npaj los ntawm sintering alumina hmoov ntawm qhov kub thiab txias thiab muaj zog lub cev.
Pressed alumina yeeb nkab: npaj los ntawm nias molding txheej txheem, feem ntau siv los npaj cov kav dej yooj yim.
Temperature Resistance Classification:
High-temperature alumina yeeb nkab: Cov yeeb nkab uas tuaj yeem tiv taus qhov kub thiab txias thiab feem ntau siv rau hauv cov txheej txheem kub kub.
Lub cev kub alumina raj: siv rau kev thauj mus los thiab kev tiv thaiv nyob rau hauv qhov kub thiab txias.
Kev faib tawm ntawm qhov chaw kho mob:
Smooth aluminium oxide raj: Qhov saum npoo yog tiaj thiab du, haum rau lub sijhawm uas yuav tsum muaj qhov siab.
Frosted alumina raj: Qhov saum npoo yog frosted los ua kom lub ntsej muag roughness, uas tuaj yeem txhim kho kev sib txhuam kev ua haujlwm thiab adhesion.
Q2: Koj yuav tsum xyuam xim rau dab tsi thaum siv alumina raj?
A2: Kev xaiv ib puag ncig kev teeb tsa: Xaiv qhov chaw tsim khoom tsim nyog los tiv thaiv lub raj alumina los ntawm kev nyob hauv ib puag ncig uas siab dhau lossis qis qis rau lub sijhawm ntev kom ntseeg tau tias nws txoj haujlwm zoo thiab lub neej ntev.
Kev txhim kho kom raug: Thaum txhim kho cov kav dej txhuas oxide, koj yuav tsum xyuas kom meej tias cov yeeb nkab sib txuas tau raug kaw zoo kom tsis txhob tawm los yog xau.
Tsis txhob sib tsoo: Thaum siv, lub raj aluminium oxide yuav tsum tau zam los ntawm kev sib tsoo nrog cov khoom tawv kom tsis txhob muaj kev puas tsuaj los yog tawg, uas yuav cuam tshuam rau nws txoj kev ua haujlwm thiab kev pab cuam lub neej.
Kev tu tsis tu ncua: ntxuav lub ntsej muag ntawm lub raj alumina kom tshem tawm cov impurities thiab residues, ua kom lub ntsej muag du, thiab pab kom ntev lub neej kev pab cuam.
Kev tshuaj xyuas tsis tu ncua: Tsis tu ncua xyuas seb puas muaj cov kab nrib pleb, hnav lossis lwm yam kev puas tsuaj rau ntawm lub raj alumina, tshawb pom thiab daws cov teeb meem hauv lub sijhawm, thiab xyuas kom meej tias nws ua haujlwm li qub.
Tsis txhob overloading: Thaum siv cov kav dej txhuas oxide, tsis txhob tshaj nws lub peev xwm load-bearing kom tsis txhob overloading, uas yuav ua rau cov yeeb nkab deformation lossis rupture.
Tsis txhob hloov qhov kub thiab txias: Sim kom tsis txhob muaj cov kav dej alumina raug qhov kub thiab txias hloov mus ntev kom tsis txhob muaj kev puas tsuaj los ntawm thermal expansion thiab contraction ntawm cov kav dej.
Ua haujlwm raws li cov lus qhia tshwj xeeb: Thaum siv cov raj alumina, koj yuav tsum ua haujlwm raws li cov lus qhia tshwj xeeb thiab cov ntawv qhia ua haujlwm kom muaj kev nyab xeeb thiab kev ntseeg tau.
