Qhov sib txawv tseem ceeb ntawm cov ntsiab lus tseem ceeb ntawm cov dej noo thiab qhov sib npaug ntawm cov dej noo yog qhov tseem ceeb ntawm cov dej noo yog qhov nruab nrab ntawm cov dej noo ntawm cov khoom thaum muaj cov ntsiab lus tseem ceeb ntawm cov khoom siv, qhov sib npaug ntawm cov dej noo ntawm cov khoom hygroscopic yog cov dej noo ntawm cov khoom uas nws tsis tau txais los yog poob ib qho dej noo.
Peb tuaj yeem txhais cov ntsiab lus tseem ceeb ntawm cov dej noo raws li qhov nruab nrab ntawm cov dej noo ntawm cov khoom thaum muaj cov ntsiab lus tseem ceeb ntawm cov khoom siv. Equilibrium noo noo cov ntsiab lus ntawm cov khoom hygroscopic, ntawm qhov tod tes, yog cov dej noo ntawm cov khoom uas nws tsis tau txais los yog poob ib qho dej noo.
Cov Ntsiab Lus Moisture yog dab tsi?
Cov ntsiab lus tseem ceeb ntawm cov dej noo tuaj yeem txhais tau tias yog qhov nruab nrab noo noo ntawm cov khoom thaum muaj cov ntsiab lus tseem ceeb ntawm cov dej noo hauv ib qho khoom. Ntawm no, qhov ziab qhuav pib poob qis. Peb tuaj yeem siv cov qauv kev ziab kom qhuav kom ua tiav qhov kev txiav txim siab ntawm cov dej noo tseem ceeb. Lo lus no yog qhov tseem ceeb tshaj plaws txog kev txheeb xyuas av.
Peb tuaj yeem faib lub sijhawm ziab ntawm cov khoom siv rau hauv peb ntu raws li lub sijhawm ua ntej lossis lub sijhawm sov so, lub sijhawm tsis tu ncua, thiab lub sijhawm poob. Nyob rau lub sijhawm ua ntej lossis ua kom sov, peb tuaj yeem soj ntsuam qhov nce ntawm qhov ziab kom txog thaum lub xeev ruaj khov tuaj. Nyob rau lub sij hawm tas mus li, tus nqi ntawm qhov diffusion ntawm cov dej dawb zoo li ntau tshaj qhov evaporation. Thaum kawg, cov ntsiab lus tseem ceeb ntawm cov khoom no tau txais thaum lub sij hawm poob, qhov twg lub sij hawm tus nqi tas mus li yuav tsum tsis tu ncua, thiab tus nqi ntawm cov ziab yuav poob nrog lub sij hawm. Nyob rau ntawm no, tus nqi ntawm evaporation ntawm qhov chaw tshaj tus nqi ntawm diffusion ntawm sab hauv cov khoom mus rau saum npoo ntawm cov khoom.
Equilibrium Moisture Content yog dab tsi?
Equilibrium noo noo cov ntsiab lus ntawm cov khoom siv hygroscopic yog cov dej noo ntawm cov khoom uas nws tsis tau txais lossis tsis muaj dej noo. Nws yog abbreviated li EMC. Feem ntau, tus nqi ntawm cov dej noo no nyob ntawm cov khoom siv, qhov kub thiab txias, txheeb ze cov av ib puag ncig cov khoom.
Daim duab 01: Equilibrium Moisture Content of Wood
Qhov nrawm ntawm kev nkag mus rau qhov sib npaug ntawm cov dej noo rau ib yam khoom yog nyob ntawm cov khoom ntawm cov khoom, qhov chaw ntawm qhov chaw-rau-ntim piv ntawm cov duab ntawm cov khoom, thiab qhov ceev ntawm nqa tawm cov av noo ntawm thiab deb ntawm cov khoom.
Hauv kev ua liaj ua teb, qhov sib npaug ntawm cov dej noo hauv cov nplej yog qhov tseem ceeb hauv kev khaws khoom noj. Cov dej noo no txiav txim siab seb qhov chaw cia khoom noj muaj kev nyab xeeb npaum li cas. Piv txwv li, nws muaj kev nyab xeeb yog tias qhov sib npaug ntawm cov dej noo yog 12% rau pob kws, sorghum, mov, thiab nplej.
Dab tsi yog qhov txawv ntawm Cov Ntsiab Lus Moisture thiab Equilibrium Moisture Content?
Qhov sib txawv tseem ceeb ntawm cov ntsiab lus tseem ceeb ntawm cov dej noo thiab qhov sib npaug ntawm cov dej noo yog qhov tseem ceeb ntawm cov dej noo yog qhov nruab nrab ntawm cov dej noo ntawm cov khoom thaum muaj cov ntsiab lus tseem ceeb hauv cov khoom siv, qhov sib npaug ntawm cov dej noo ntawm cov khoom siv hygroscopic yog cov dej noo ntawm cov khoom uas nws tsis tau txais los yog poob ib qho dej noo. Kev nkag siab txog cov ntsiab lus tseem ceeb ntawm cov av yog qhov tseem ceeb heev hauv kev txheeb xyuas av hauv kev ua liaj ua teb. Ib yam li ntawd, qhov sib npaug ntawm cov dej noo feem ntau yog siv los ntawm kev khaws cov noob hauv kev tshawb fawb txog zaub mov.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov ntsiab lus tseem ceeb ntawm cov dej noo thiab cov dej noo sib npaug hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Cov ntsiab lus moisture tseem ceeb vs Equilibrium Moisture Content
Kev nkag siab txog qhov tseem ceeb ntawm cov av noo yog qhov tseem ceeb hauv kev txheeb xyuas av hauv kev ua liaj ua teb. Ib yam li ntawd, qhov sib npaug ntawm cov dej noo feem ntau yog siv los ntawm kev khaws cov noob hauv kev tshawb fawb zaub mov. Qhov sib txawv tseem ceeb ntawm cov ntsiab lus tseem ceeb ntawm cov dej noo thiab qhov sib npaug ntawm cov dej noo yog tias cov ntsiab lus tseem ceeb ntawm cov dej noo yog qhov nruab nrab ntawm cov dej noo ntawm cov khoom thaum muaj cov ntsiab lus tseem ceeb ntawm cov khoom siv, qhov sib npaug ntawm cov dej noo ntawm cov khoom siv hygroscopic yog cov dej noo ntawm cov khoom. cov khoom uas nws tsis tau txais los yog poob ib qho dej noo.
