Ntau tus neeg ntseeg yuam kev tias "dawb ntoo qhib yog liab ntoo qhib, thiab ntoo qhib dawb yog ntoo qhib." Qhov tseeb, qhov no tsis yog qhov xwm txheej. Qhov laj thawj vim li cas cov ntoo qhib liab hu ua liab ntoo qhib yog vim nws cov nplooj tig mus rau hauv cov ntoo qhib liab thaum lub caij nplooj zeeg. liab. Raws li keeb kwm ntawm lub npe Dawb Oak, kuv tsis paub meej. Koj puas xav paub yuav ua li cas paub qhov txawv ntawm cov ntoo qhib liab los ntawm cov ntoo qhib dawb?
Ua ntej tshaj plaws, koj yuav tsum nkag siab tias qhov peb hu ua dawb ntoo qhib lossis liab ntoo qhib txhua hnub yog lub ntsiab lus dav dav rau ntau hom ntoo qhib. Dawb ntoo qhib tsis yog hais txog ib hom ntoo qhib, thiab cov ntoo qhib liab tsis hais txog qee hom ntoo qhib, txawm hais tias muaj tseeb ib hom hu ua Quercus alba, uas txhais tau tias yog ntoo qhib dawb, thiab tseem muaj ib hom hu ua Quercus. rub. Cov lus txhais ntawm tsob ntoo hom yog liab ntoo qhib. Botanically, lawv zwm rau cov genus Quercus (tseem hu ua Quercus, feem ntau hu ua ntoo qhib, ntoo qhib, lossis ntoo qhib), uas yog cov genus hauv tsev neeg Fagaceae.
Cov ntoo qhib dawb thiab cov ntoo qhib liab uas peb yuav los ntawm lub khw yuav yog ib lossis ntau hom ntoo qhib nrog rau ob pawg loj (cov ntoo qhib liab thiab cov ntoo qhib dawb), tab sis nws tsis tas yuav muaj tseeb, vim tias tseem muaj qee qhov uas peb tau ua. 'tsis paub Oak ntoo hom muaj nyob, yog li cov ntoo qhib uas peb yuav yuav tsis yog ib qho ntawm cov pawg saum toj no cov ntoo qhib liab thiab cov ntoo qhib dawb, thiab qhov ua tau yog siab heev.
Nkag siab cov ntsiab lus saum toj no, peb tuaj yeem paub qhov txawv ntawm cov ntoo qhib dawb thiab cov ntoo qhib liab los ntawm cov npe ntoo. Hauv qab no peb yuav saib qee lwm txoj hauv kev kom paub qhov txawv ntawm ob hom ntoo.
saib xim
Lub sapwood ntawm liab Oak yog dawb mus rau lub teeb xim av, thiab lub heartwood yog pinkish xim av. Lub sapwood ntawm dawb ntoo qhib yog lub teeb nyob rau hauv cov xim thiab lub heartwood yog lub teeb xim av mus rau tsaus xim av.
Rau cov neeg tsis paub, nws yog qhov nyuaj me ntsis kom paub qhov txawv ntawm cov ntoo qhib liab thiab dawb ntoo qhib los ntawm xim.
Saib ntawm ntoo hla ntu
Saib xyuas kev loj hlob ntawm cov ntoo qhib liab nyob rau hauv lub iav loj, koj tuaj yeem pom tias cov hlab ntsha ntawm tes muaj ntau qhov thiab khoob hauv, uas yuav tsum yooj yim txheeb xyuas. Muaj cov khoom impregnating hauv lub raj qhov ntawm cov ntoo qhib dawb. Txawm hais tias nws yog qhov sib txawv me ntsis, qhov no ua rau cov ntoo qhib dawb muaj cov khoom zoo tiv thaiv corrosion thiab kab pov thawj thiab cov dej zoo dua, yog li nws tuaj yeem dhau los ua cov khoom siv ntoo qhib thoob ntiaj teb, thaum cov ntoo qhib liab tsis tuaj yeem. Ua cov cawv txiv hmab.
Nitrite (NaNO2) test
Txoj kev no yog qhov tseeb thiab txhim khu kev qha. Txawm hais tias nws yog me ntsis overkill, nws tseem tuaj yeem siv thaum lub cev tsis ua haujlwm. CEEB TOOM: Nitrite tsuas tuaj yeem ua rau cov xim hloov hauv cov ntoo.
Hauv qab no peb yuav siv cov txheej txheem sim los qhia koj paub qhov txawv ntawm cov ntoo qhib liab thiab dawb ntoo qhib:
Ua ntej, peb yuav tsum tau npaj lub plawv ntawm cov ntoo qhib liab thiab dawb ntoo qhib, thiab tom qab ntawd siv 10% nitrite tov (sodium nitrite tov nrog ib qho concentration ntawm 1% mus rau 20% tuaj yeem ua tiav qhov kev sim. Ntawm no peb xav kom qhov zoo tshaj plaws concentration. 10%).
Yog hais tias lub plawv ntawm cov ntoo qhib liab yog coated nrog nitrite tov, cov xim yuav tsis hloov ntau npaum li lub sij hawm mus. Nws txhais tau tias nws yuav tsaus me ntsis, thiab qee zaum nws yuav tig ntsuab me ntsis. Tab sis yog hais tias nws yog lub heartwood ntawm dawb ntoo qhib, xim yuav hloov obviously. Cov xim yuav hloov los ntawm cov xim ntuj rau cov xim maroon, ces maj mam mus tob indigo xiav, thiab thaum kawg yuav luag dub.
Saib nplooj
Qhov no yog txoj kev ua tau zoo tshaj plaws thiab yooj yim tshaj plaws. Koj tuaj yeem paub qhov txawv ntawm cov ntoo qhib liab los ntawm cov ntoo qhib dawb los ntawm kev sib piv cov duab ntawm nplooj. Liab Oak nplooj muaj taw npoo, thaum dawb ntoo qhib nplooj muaj cov npoo npoo.
Lub cev muaj zog
Thaum kawg, lub cev lub cev ntawm cov ntoo qhib liab thiab dawb ntoo qhib kuj txawv, tab sis qhov no kuj muaj feem xyuam rau lawv cov keeb kwm. Cov ntaub ntawv hauv lub rooj tsuas yog sawv cev rau ob hom ntoo uas tsim nyob rau sab qaum teb sab hnub tuaj Tebchaws Meskas.
