Yuav ntsuas cov dej noo ntawm daim ntawv li cas nrog Wood Moisture Meter?
Cov ntsiab lus noo noo ntawm daim ntawv yog hais txog qhov sib piv ntawm qhov txo qis ntawm cov qauv ntawv thaum nws nce mus txog "qhov hnyav tas li" ntawm qhov ntsuas kom qhuav (105 ± 2)℃rau qhov qub, qhia raws li feem pua.
Txoj kev txiav txim siab cov ntsiab lus noo noo yog coj ob qho piv txwv ntawm qee qhov loj (qhov tseeb rau 0.0001g), muab tso rau hauv "lub raj mis hnyav" uas twb tau hnyav lawm, thiab ziab lawv hauv qhov cub cua kub kom qhuav rau ob peb teev (feem ntau 4 teev). Tom qab txias rau 30 feeb, hnyav lawv. Yog tias qhov kev xav tau tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, qhuav ntau zaus kom txog thaum qhov hnyav tas li. Tom qab ntawd, faib qhov sib txawv ntawm pawg ua ntej thiab tom qab ziab los ntawm qhov loj ua ntej ziab, thiab los ntawm kev suav yooj yim, tau txais cov dej noo ntawm daim ntawv.
Huab cua feem ntau muaj qee qhov dej noo. Thaum cov av noo nyob rau hauv cov huab cua ntau dua li hauv ntawv, uas yog, thaum huab cua ntub, daim ntawv yuav nqus cov dej noo hauv huab cua. Ntawm qhov tsis sib xws, thaum huab cua qhuav, cov dej noo hauv daim ntawv yuav desorb thiab hloov mus rau huab cua kom txog thaum muaj qhov sib npaug ntawm cov dej noo ntawm ob. Nws yuav tsum tau muab sau tseg tias cov adsorption thiab desorption teebmeem yog manifested li ob isotherms, thiab lub desorption nkhaus yog nyob rau saum toj ntawm lub adsorption nkhaus (lub npe hu ua hysteresis phenomenon). Yog li, cov dej noo ntawm cov ntawv hloov pauv nrog qhov kub thiab txias ntawm huab cua. Feem ntau, cov dej noo nyob hauv huab cua yog li 7%, thiab cov ntsiab lus noo noo ntawm cov ntawv luam ntawv zoo tib yam yog 7% ± 2%. Yog tias nws dhau qhov kev txwv no, nws txhais tau hais tias cov dej noo hauv daim ntawv tsis tsim nyog, thiab koj tuaj yeem thov nyiaj los ntawm cov tub lag luam.
Cov dej noo ntawm daim ntawv tuaj yeem cuam tshuam rau ntau yam ntawm nws cov khoom. Los ntawm kev xav luam ntawv, noo noo yuav luag cuam tshuam rau ntawm daim ntawv loj, ncab tus nqi, tensile lub zog, lub zog nto, thiab lwm yam, uas tsis tuaj yeem kwv yees. Cov dej noo ntau dhau ntawm daim ntawv tuaj yeem ua rau overprinting nyuaj, ncua sij hawm tus number case kom qhuav, thiab txo tensile thiab deg zog; Cov dej noo ntawm daim ntawv yog tsawg dhau, uas tuaj yeem ua rau daim ntawv nto nkig thiab yooj yim tsim hluav taws xob zoo li qub, ua rau muaj teeb meem zoo xws li "ob nplooj ntawv" thiab "dawb nplooj ntawv" thaum luam ntawv.
