1. Tsawg khiav tsis kam
Vim hais tias sab hauv ntawm alumina hnav-resistant ceramic yeeb nkab yog du thiab tsis xeb, tsis muaj convex helix nyob rau sab hauv ntawm seamless steel yeeb nkab. Qhov roughness ntawm sab hauv thiab cov yam ntxwv ntawm cov dej huv uas tau kuaj los ntawm cov kev ntsuam xyuas cuam tshuam qhia tau tias qhov smoothness ntawm sab hauv yog zoo dua li cov yeeb nkab hlau, thiab cov coefficient kuj yog 0.0193, qis dua qhov ntawd. ntawm seamless yeeb nkab. Yog li ntawd, cov yeeb nkab muaj cov yam ntxwv ntawm kev ua haujlwm me me, uas tuaj yeem txo cov nqi khiav lag luam.
2. Siab hardness
Raws li cov hauv ob sab hauv ntawm alumina hnav-resistant ceramic yeeb nkab yog corundum ceramic (a-AL2O3), Mohs hardness tuaj yeem ncav cuag 9.0, uas yog sib npaug rau HRC85. Yog li ntawd, nws muaj siab hnav tsis kam mus rau kev sib tsoo xov xwm thauj los ntawm metallurgy, hluav taws xob fais fab, mining thiab lwm yam lag luam. Nws tau raug pov thawj los ntawm kev lag luam kev lag luam uas nws hnav tsis kam lub neej yog kaum lossis txawm kaum ob lub sijhawm ntawm cov hlau quenched.
3. Lub neej ua haujlwm ntev
Raws li cov txheej txheem ceramic ntawm cov hlau yog (a-AL2O3), nws yog nruab nrab. Yog li ntawd, nws muaj kua qaub thiab alkali tsis kam thiab seawater corrosion kuj, nrog rau kev tiv thaiv scaling thiab lwm yam ntxwv, uas tuaj yeem ua rau lub neej ntev ntawm cov kav dej.
4. Zoo kub tsis kam
Vim hais tias corundum ceramic (a-AL2O3) yog ib qho ruaj khov crystalline qauv. Yog li ntawd, cov yeeb nkab sib xyaw tuaj yeem ua haujlwm ib txwm siv sijhawm ntev hauv qhov kub thiab txias ntawm - 50-700 degree . Linear expansion coefficient ntawm cov khoom siv 6-8 × 10-6/0C, txog 1/2 ntawm cov yeeb nkab steel. Cov khoom muaj thermal stability zoo.
5. Tsawg qhov project nqi
Lub alumina hnav-resistant ceramic raj yog lub teeb hauv qhov hnyav thiab pheej yig. 50 feem pua sib dua li cov cam khwb cia pob zeb yeeb nkab nrog tib txoj kab uas hla; Nws yog 20-30 feem pua sib dua li cov yeeb nkab hnav-resistant alloy, thiab muaj kev hnav zoo thiab corrosion kuj. Vim nws lub neej ua haujlwm ntev, cov nqi them nyiaj yug thiab hanger, cov nqi tuav, cov nqi siv thiab cov nqi khiav lag luam raug txo. Raws li qhov project pob nyiaj siv thiab qhov project sib piv ntawm cov koom haum tsim thiab kev tsim kho, qhov project tus nqi ntawm cov yeeb nkab yog sib npaug rau cov pob zeb cam khwb cia, thiab qhov project tus nqi raug txo los ntawm 20 feem pua piv nrog cov yeeb nkab-resistant alloy. .
6. Yooj yim installation thiab tsim
Vim nws lub teeb yuag thiab zoo weldability. Yog li ntawd, vuam, flange, kev sib txuas ceev thiab lwm txoj hauv kev tuaj yeem siv los pab txhawb kev tsim kho thiab kev teeb tsa thiab txo cov nqi installation.
