Cov khoom siv granite feem ntau siv rau hauv cov khoom siv computer tomography kom ntseeg tau tias qhov tseeb thiab qhov tseeb ntawm cov txiaj ntsig. CT scanning thiab metrology xav tau qib siab ntawm qhov tseeb, thiab cov khoom siv granite siv los xyuas kom meej tias cov tshuab ua haujlwm tau zoo. Hauv tsab xov xwm no, peb yuav tham txog cov kev cai ntawm cov khoom siv granite rau cov khoom siv computer tomography hauv kev lag luam ntawm qhov chaw ua haujlwm thiab yuav ua li cas tswj hwm qhov chaw ua haujlwm.
Cov Kev Cai ntawm Granite Cheebtsam rau Cov Khoom Siv CT Muaj
Cov khoom siv granite muaj qhov ruaj khov siab, qhov nthuav dav thermal tsawg, thiab qhov coefficient ntawm thermal nthuav dav qis. Cov yam ntxwv no ua rau lawv tsim nyog rau kev siv hauv cov khoom siv computer tomography hauv kev lag luam. Cov khoom siv granite tuaj yeem siv ua lub hauv paus rau theem tig ntawm lub scanner, nrog rau lub hauv paus rau lub gantry uas tuav lub scanner. Txhawm rau kom ntseeg tau tias cov khoom siv granite ua haujlwm tau zoo, yuav tsum tswj hwm qee qhov xwm txheej ib puag ncig. Cov hauv qab no yog cov kev cai ntawm cov khoom siv granite rau cov khoom siv computer tomography hauv kev lag luam ntawm qhov chaw ua haujlwm:
1. Kev Tswj Kub
Yuav tsum tswj qhov kub thiab txias kom zoo hauv qhov chaw ua haujlwm kom tsis txhob muaj kev hloov pauv ntawm qhov kub thiab txias thiab xyuas kom lub tshuab microscope ua haujlwm tau zoo. Qhov kub ntawm qhov chaw ua haujlwm yuav tsum sib xws thoob plaws hnub, thiab qhov hloov pauv ntawm qhov kub thiab txias yuav tsum tsawg kawg nkaus. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom nyob deb ntawm cov chaw kub xws li lub tshuab cua sov, lub tshuab cua txias, thiab lub tub yees.
2. Kev Tswj Av noo
Kev tswj kom muaj qhov av noo sib xws kuj tseem ceeb ib yam li kev tswj qhov kub thiab txias. Qhov av noo yuav tsum tau khaws cia rau ntawm qhov pom zoo kom tsis txhob muaj dej noo los ua pa. 20% -55% yog qhov pom zoo kom ua qhov av noo sib xws rau kev tswj qhov tseeb thiab kev ua haujlwm zoo ntawm cov txheej txheem luam theej duab.
3. Kev Huv Si
Ib puag ncig huv si yog qhov tseem ceeb rau qhov tseeb ntawm cov khoom siv computer tomography hauv kev lag luam. Qhov tseeb ntawm cov txiaj ntsig tuaj yeem raug cuam tshuam thaum muaj cov kuab paug xws li hmoov av, roj, thiab roj ntau nyob rau hauv qhov chaw luam theej duab. Yuav kom tswj tau ib puag ncig huv si, nws yog ib qho tseem ceeb uas yuav tsum ntxuav cov khoom granite thiab chav tsev tsis tu ncua.
4. Teeb pom kev zoo
Nws yog ib qho tseem ceeb uas yuav tsum tswj kom muaj lub teeb pom kev zoo tas li hauv qhov chaw ua haujlwm. Lub teeb pom kev zoo tsis zoo tuaj yeem ua rau qhov tseeb ntawm cov duab luam theej tsis raug. Yuav tsum tsis txhob muaj lub teeb ntuj, thiab nws yog qhov zoo tshaj plaws los siv lub teeb dag uas tas li thiab tsis ci dhau.
Yuav Ua Li Cas Thiaj Tswj Tau Ib Puag Ncig Ua Haujlwm
Yuav kom tswj tau ib qho chaw ua haujlwm kom raug, cov kev coj ua hauv qab no tuaj yeem pab tau:
1. Teeb tsa ib puag ncig chav huv si
Yuav kom tswj tau qhov chaw ua haujlwm kom huv si, yuav tsum muaj chav huv. Nws yog tsim los tswj cov khoom me me thiab tiv thaiv kev ua qias tuaj. Chav huv muab cov xwm txheej ib puag ncig tsim nyog rau cov khoom siv computer tomography hauv kev lag luam.
2. Khaws qhov kub kom sib xws
Kev tswj qhov kub thiab txias yog qhov tseem ceeb heev rau cov khoom siv computer tomography kom ua haujlwm tau zoo. Nws yog ib qho tsim nyog los tswj qhov kub thiab txias tas li ntawm 20-22 ° C hauv qhov chaw ua haujlwm. Yuav kom ua tiav qhov no, nws yog ib qho tseem ceeb kom kaw cov qhov rooj thiab qhov rai, nrog rau txo qhov qhib thiab kaw ntawm cov qhov rooj.
3. Tswj cov av noo
Kev tswj kom muaj ib puag ncig zoo ib yam yog qhov tseem ceeb rau qhov tseeb ntawm cov khoom siv computer tomography hauv kev lag luam. Yog li ntawd, nws yog ib qho tsim nyog los tswj cov av noo. Cov av noo yuav tsum txo kom qis dua 55%, thiab cov chaw yuav tsum qhuav kom txo qhov kev pheej hmoo ntawm cov av noo.
4. Kev Ntxuav Kom Zoo
Yuav kom paub tseeb tias ib puag ncig huv si, cov khoom granite thiab cov chaw ua haujlwm yuav tsum tau ntxuav nrog isopropyl cawv. Cov txheej txheem ntxuav yuav tsum tau ua tsis tu ncua kom paub tseeb tias ib puag ncig huv si.
Xaus lus
Xaus lus, kev tswj hwm qhov chaw ua haujlwm rau cov khoom siv computer tomography hauv kev lag luam yog qhov tseem ceeb heev. Ib puag ncig yuav tsum tsis muaj cov pa phem, thiab qhov kub thiab av noo yuav tsum tau tswj hwm ntawm cov qib tshwj xeeb. Kev xyaum cov lus qhia saum toj no tuaj yeem pab tswj hwm qhov chaw ib puag ncig kom raug rau cov khoom siv computer tomography hauv kev lag luam. Qhov no yuav ua kom ntseeg tau tias cov khoom granite siv hauv CT scanning thiab metrology tshuab tuaj yeem ua haujlwm tau zoo thiab muab cov txiaj ntsig tseeb.
