1.Cov yam ntxwv ntawm kev hloov xiav

Feem ntau tshwm sim tsuas yog ntawm sapwood ntawm ntoo, thiab tuaj yeem tshwm sim hauv ob qho tib si coniferous thiab broadleaf ntoo.

Nyob rau hauv cov xwm txheej zoo, blueing feem ntau tshwm sim ntawm qhov chaw ntawm cov ntoo sawn thiab qhov kawg ntawm cov cav ntoo. Yog tias cov xwm txheej tsim nyog, cov kab mob xiav-xim tuaj yeem nkag mus los ntawm cov ntoo saum npoo mus rau sab hauv ntawm cov ntoo, ua rau cov xim sib sib zog nqus.

Lub teeb-xim ntoo yog qhov cuam tshuam rau kev kis kab mob xiav, xws li cov ntoo ntoo, ntoo thuv liab, ntoo thuv ntoo, willow press, thiab maple.

Kev hloov xiav tsis cuam tshuam rau cov qauv thiab lub zog ntawm cov ntoo, tab sis cov khoom tiav ua los ntawm cov ntoo hloov xiav muaj qhov pom kev tsis zoo thiab nyuaj rau cov neeg siv khoom.

Cov neeg siv khoom txaus siab tuaj yeem pom tias muaj qee qhov kev hloov pauv ntawm cov xim ntawm qee cov rooj tog zaum, cov plag tsev lossis cov phaj hauv tsev, uas cuam tshuam rau kev zoo nkauj tag nrho. Qhov no yog dab tsi? Vim li cas ntoo hloov xim?

Kev kawm, peb sib sau ua ke hu ua kev hloov xim ntawm ntoo sapwood xiav, tseem hu ua xiav. Ntxiv nrog rau xiav, nws kuj suav nrog lwm cov xim hloov, xws li dub, liab, ntsuab, thiab lwm yam.

2.Incentives rau Blue Hloov

Tom qab cov ntoo raug txiav, lawv tsis tau kho raws sijhawm thiab ua tau zoo. Hloov chaw, tag nrho tsob ntoo tau muab tso ncaj qha rau ntawm cov av ntub, thiab nws raug cua thiab nag thiab kab mob. Thaum cov dej noo ntawm cov ntoo siab dua 20%, qhov chaw sab hauv ntawm cov ntoo tuaj yeem hloov pauv, thiab cov ntoo zoo li lub teeb xiav.

Plain boards (dawb boards tsis muaj kev tiv thaiv corrosion thiab pleev xim) kuj tseem tshuav nyob rau hauv qhov chaw ntub dej thiab tsis muaj huab cua ntev, thiab lawv kuj yuav muaj cov tsos mob xiav.

Cov ntsiab lus ntawm cov hmoov txhuv nplej siab thiab monosaccharides hauv cov ntoo roj hmab yog ntau dua li lwm cov ntoo, thiab nws muab lub zog xav tau rau kev loj hlob ntawm cov kab mob xiav. Yog li ntawd, cov roj hmab ntoo yog feem ntau ua rau blueing dua lwm cov ntoo.

3.Qhov kev phom sij ntawm kev hloov pauv xiav

Blue ntoo yog ntau perishable

Feem ntau, ntoo yog blued ua ntej nws decays. Qee lub sij hawm nws tuaj yeem pom tsuas yog qhov pom tseeb qhov tsis xws luag tsim thaum lub sijhawm tom qab ntawm xiav. Nws tseem tuaj yeem hais tau tias kev hloov xim yog qhov ua ntej rau kev lwj.

Discoloration nce permeability ntawm ntoo

Vim yog qhov nkag mus ntawm xiav-fungal mycelium, ntau qhov me me tau tsim, uas ua rau kom muaj qhov permeability ntawm ntoo. Lub hygroscopicity ntawm blued ntoo tom qab ziab yog nce, thiab cov kab mob lwj yog yooj yim loj hlob thiab rov tsim dua tom qab nqus dej.

Txo nqi ntoo

Vim qhov tsis muaj xim, qhov tsos ntawm ntoo tsis zoo-zoo li. Cov neeg siv feem ntau tsis kam lees txais cov ntoo uas tsis muaj xim lossis cov khoom siv ntoo, tshwj xeeb tshaj yog cov uas siv rau hauv cov ntoo zoo nkauj, rooj tog zaum, thiab lwm qhov chaw uas cov ntoo zoo li tseem ceeb dua, lossis xav tau kev txo nqi. Kev lag luam, kev tiv thaiv kev hloov xim ntoo yog qhov tseem ceeb ntawm kev tswj hwm tus nqi ntawm cov khoom ntoo.

4. Tiv thaiv kom tsis muaj xim xiav

Tom qab txiav tawm, cov cav yuav tsum tau ua tiav sai li sai tau, qhov sai dua qhov zoo dua.

Cov ntoo ua tiav yuav tsum tau qhuav kom sai li sai tau kom txo cov dej noo ntawm cov ntoo kom qis dua 20%.

Kho ntoo nrog cov tshuaj tiv thaiv tarnish raws sijhawm.
