Vim li cas kuv thiaj siv lub ntsuas dej noo ntawm ntoo?
Qhov no tej zaum yuav yog ib lo lus nug ntawm cov neeg siv uas siv lub hygrometer thawj zaug. Txawm hais tias cov lus teb tshwj xeeb rau lo lus nug no yuav txawv ntawm kev lag luam, cov lus teb no feem ntau cuam tshuam txog qhov zoo.
Siv lub tshuab hygrometer, koj tuaj yeem ntsuas qhov teeb meem uas cov qauv ntawm cov ntoo tuaj yeem ntsib, xws li tawg, shrinkage, splitting, pwm loj hlob, thiab lwm yam. Thaum cov dej noo ntawm cov ntoo siab dhau (los yog tsawg dhau, hauv qee qhov rooj plaub), qhov zoo ntawm cov khoom kawg yuav raug cuam tshuam.
Kev siv lub hygrometer tuaj yeem pab koj kom ntseeg tau tias cov dej noo ntawm cov khoom siv ntoo siv nyob rau hauv qhov tseeb ntawm feem pua MC kom tsis txhob hu rov qab rau yav tom ntej.
Dab tsi yog qhov txawv ntawm cov ntoo noo noo testers?
Txawm hais tias muaj ntau tus qauv hygrometer hauv khw, thiab cov hygrometers tshiab tau tshwm sim, lawv tau muab faib ua ob pawg raws li lawv txoj haujlwm:
Koob suab.
Koob pub mov.
Ib rab koob hygrometer siv ob (lossis ntau dua) electrodes nkag mus rau cov khoom siv ntoo los nyeem cov feem pua MC ntawm cov khoom siv lub hauv paus ntsiab lus ntawm kev tiv thaiv. Hauv ob tus pin ntsuas, ib tus pin tawm tam sim no thiab lwm tus pin tau txais tam sim no, thiab lub ntsuas ntsuas txhais qhov impedance ntawm tam sim no mus rau tam sim no. Vim lub fact tias ntoo yog ib tug insulator thiab dej yog ib tug conductor, qhov me me ntawm qhov tsis kam ntawm tam sim no, qhov siab dua cov dej noo ntawm cov ntoo.
Ntawm qhov tod tes, rab koob tsis pub ntsuas siv hluav taws xob hluav taws xob hauv xov tooj cua yoj ntsuas ntsuas los ntsuas cov qauv ntoo hauv qab lub rooj tsavxwm. Cov cuab yeej no qee zaum hu ua non-invasive hygrometers vim tias lawv tsis tas yuav nkag mus rau lub cev ntawm cov ntoo kom tau txais kev nyeem ntawv.
Hom dej ntsuas twg zoo dua?
Tom qab nug txog ntau hom kev ntsuas dej noo, cov neeg feem coob tseem xav paub seb hom ntsuas dej noo twg yog qhov zoo. Cov lus teb feem ntau yog nyob ntawm hom kev ua haujlwm uas koj ua haujlwm, qhov loj ntawm cov khoom ntoo uas koj siv, txawm tias cov pinholes tau tso rau hauv cov khoom, thiab koj tus kheej nyiam.
Cov koob tsawg dua qhov ntsuas tau nrawm nrawm thiab yuav tsis ua rau lub ntsej muag ntawm cov khoom scanned. Ntawm qhov tod tes, pins tuaj yeem muab cov ntaub ntawv tshwj xeeb rau koj txog kev faib cov dej noo hauv cov ntoo.
Ntau tus kws tshaj lij siv ob hom cuab yeej hauv lawv txoj haujlwm thiab hloov ntawm lawv thaum tsim nyog.
