Cov lus qhia yuav ua li cas ntsuas cov dej noo cov ntoo ntawm cov ntoo rau DIY cov phiaj xwm
Ib qho ntawm cov txheej txheem qub tshaj plaws rau kev ntsuas cov ntsiab lus ya raws ntawm cov khoom siv hygroscopic yog qhov cub kom qhuav. Qhov kev ntsuas no muaj ob txoj kev tau piav qhia nyob rau hauv ASTM D4442, MAYS B (raug xa mus rau "kev tshawb fawb" kev tshawb fawb ", ntsig txog).
Cov tswv yim dav dav rau kev siv tshuab qhib tshuab ziab yog kom qhuav ntoo hauv qhov cub ua cua txias lossis lub sijhawm ntev. Tom qab txhua lub voj voog ziab, hnyav ntoo kom paub tseeb nws qhov hnyav. Rov ua cov txheej txheem no kom txog thaum qhov hnyav ntawm cov ntoo nres hloov.
Los ntawm kev sib piv qhov hnyav ntawm cov ntoo nrog nws thawj qhov hnyav, koj tuaj yeem tsim cov nyiaj tau qub heev qub qub.
Piv txwv li, Piv txwv tias koj muaj ib daim ntoo uas muaj 10 phaus thiab dhau los ntawm qhov cub kom kom txog thaum nws poob 9.5 phaus. Hauv qhov no,% MC ntawm Ntoo yog kwv yees li 5%, raws li 0.5 phaus ntoo yog dej, thiab 0.5 /10=0.05 lossis 5%.
In general, oven drying testing is considered an accurate method for determining moisture content in moisture absorbing materials such as wood - assuming the test is conducted properly.
Txawm li cas los xij, DIY tus yam txaus siab feem ntau tsis nyiam cov qauv no rau cov laj thawj hauv qab no:
Qhov no yog qeeb heev. Kuaj cov dej noo los ntawm ziab ntoo ua piv txwv yuav siv ob peb teev, thiab cov txheej txheem dej ntws tuaj yeem hlawv thiab puas tsuaj ntoo.
Hauv ntau zaus, muab cov ntoo kuaj xyuas cov ntoo tsis tuaj yeem siv. Txawm hais tias% MC tau txiav txim siab los ntawm qhov hnyav ntawm cov dej hauv tus txheej txheem no, dhau ntawm kev siv cov khoom qhuav yuav tsis haum los ntawm kev ua kom sov thiab ua kom qhuav.
Tsis yog txhua tus muaj lub qhov cub haum. Kev cob qhia cov kws txua ntoo tsuas tuaj yeem siv cov kilns rau ziab ntoo, tab sis cov qhov cub tsis tuaj yeem tiv thaiv ncu, uas tuaj yeem ua tiav lub hom phiaj ntawm tusyees ziab ntoo. Qhov cub uas tsis tuaj yeem tswj qhov ntsuas kub tsim nyog lossis muab cov cua txaus yuav ua rau muaj kev sib txawv hauv kev sim.
Peb nqe lus nug no ib leeg yog qhov txaus los tiv thaiv tus kheej feem ntau-}}}}}}}} pab txhawb kev siv qhov cub kom cov phiaj xwm woodworking.
Txawm li cas los xij, muaj txoj kev sai los xyuas cov ntsiab lus noo noo ntawm cov ntoo, uas yog tseem txhim khu kev qha txaus rau koj txoj haujlwm DIY Wood Kev sim:
