Cov khoom siv twg uas ruaj khov tshaj? Thaum nws los txog rau cov khoom siv uas tuaj yeem tiv taus kev hnav thiab rhuav, muaj ob peb txoj kev xaiv uas koj xav txog. Ob qho khoom siv uas siv rau kev siv uas tiv taus kev sib txhuam yog alumina ceramics thiab silicon carbide ceramics.
Alumina ceramics, tseem hu ua aluminium oxide, yog ib hom ceramic uas tiv taus kev hnav thiab tsim kua muag heev. Cov khoom siv no yog tsim los ntawm aluminium oxide, uas muaj cov khoom tawv thiab tawv heev. Alumina ceramics feem ntau yog siv ua cov khoom siv tiv taus kev sib txhuam hauv ntau yam lag luam, suav nrog kev khawb av, cement, thiab kev tsim hluav taws xob.
Lwm hom ceramic uas feem ntau siv rau kev siv uas tiv taus kev sib txhuam yog silicon carbide ceramics. Silicon carbide yog ib yam khoom uas muaj silicon thiab carbon, thiab paub txog nws qhov nyuaj thiab tiv taus kev hnav thiab tsim kua muag. Silicon carbide ceramics yog siv rau hauv kev lag luam xws li tsheb thiab aerospace, nrog rau kev tsim cov cuab yeej txiav thiab cov khoom siv sib txhuam.
Thaum nws los txog rau kev xaiv ntawm alumina ceramics thiab silicon carbide ceramics rau kev siv uas tiv taus kev sib txhuam, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov. Txawm hais tias ob qho tib si cov ntaub ntawv no tiv taus kev hnav thiab tsim kua muag, lawv muaj cov yam ntxwv sib txawv uas yuav ua rau ib qho tsim nyog dua rau ib daim ntawv thov tshwj xeeb dua li lwm qhov.
Piv txwv li, alumina ceramics paub txog lawv cov tshuaj lom neeg siab thiab thermal stability. Qhov no ua rau lawv zoo tagnrho rau kev siv rau hauv cov ntawv thov uas raug rau cov tshuaj lom neeg hnyav lossis kub siab yog qhov txhawj xeeb. Ntawm qhov tod tes, silicon carbide ceramics paub txog lawv lub zog siab thiab hardness, uas ua rau lawv haum rau cov ntawv thov uas xav tau cov qib siab ntawm kev tiv thaiv kev sib txhuam.
Ib qho kev siv uas cov khoom siv tiv taus kev sib txhuam feem ntau yog nyob rau hauv daim ntaub ntawm cov chutes. Cov chutes yog siv los thauj cov khoom los ntawm ib qho chaw mus rau lwm qhov, thiab feem ntau yuav raug hnav thiab rhuav vim yog qhov xwm txheej ntawm cov khoom siv uas raug thauj mus los. Yuav kom tiv thaiv kev puas tsuaj rau lub chute thiab xyuas kom meej tias lub neej ua haujlwm ntev, nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom siv uas tuaj yeem tiv taus kev sib txhuam.
Chemshun Ceramics-Cov yam ntxwv ntawm cov kav dej ceramicyog ib qho kev xaiv zoo heev rau cov ntawv thov uas xav tau kev tiv thaiv kev sib txhuam. Alumina ceramics thiab silicon carbide ceramics ob leeg feem ntau siv rau chute liners vim lawv cov qib siab ntawm kev tiv thaiv kev sib txhuam. Ntxiv rau lawv qhov kev tiv thaiv kev hnav thiab tsim kua muag, ceramic chute liners kuj paub txog lawv lub peev xwm los txo cov suab nrov thiab kev co, uas tuaj yeem pab tau rau qee qhov kev siv.
Xaus lus, thaum nws los txog rau cov ntaub ntawv uas tiv taus kev sib txhuam, alumina ceramics thiab silicon carbide ceramics yog ob qho kev xaiv uas siv ntau tshaj plaws. Ob qho ntaub ntawv no tiv taus kev hnav thiab tsim kua muag heev, tab sis muaj cov yam ntxwv sib txawv uas yuav ua rau ib qho tsim nyog dua rau ib daim ntawv thov tshwj xeeb dua li lwm qhov. Cov kab xev ceramic yog ib daim ntawv thov zoo heev rau ob hom ceramics, vim lawv muaj peev xwm tiv taus qhov xwm txheej ntawm cov ntaub ntawv raug thauj mus los thaum tseem txo cov suab nrov thiab kev co.
