1.Makhalidwe a kusintha kwa buluu

Nthawi zambiri amapezeka pamtengo wamtengowo, ndipo amatha kuchitika pamitengo yonse ya coniferous ndi broadleaf.

Pamikhalidwe yoyenera, buluu nthawi zambiri limapezeka pamwamba pa matabwa ocheka ndi malekezero a matabwa. Ngati mikhalidwe ili yoyenera, mabakiteriya amtundu wa buluu amatha kudutsa kuchokera pamtengo mpaka mkati mwa matabwa, zomwe zimapangitsa kuti khungu likhale lozama.

Mitengo yopepuka imatha kugwidwa ndi mabakiteriya a buluu, monga rubberwood, red pine, masson pine, willow press, ndi mapulo.

Kusintha kwa buluu sikukhudza mapangidwe ndi mphamvu za matabwa, koma chotsirizidwa chopangidwa ndi buluu chosinthika cha buluu chimakhala ndi zotsatira zosaoneka bwino ndipo zimakhala zovuta kuvomerezedwa ndi makasitomala.

Makasitomala atcheru angapeze kuti pali kusintha kwa mtundu wa mipando, pansi kapena mbale m'nyumba, zomwe zimakhudza kukongola konse. Kodi ichi ndi chiyani kwenikweni? N’chifukwa chiyani matabwa amasintha mtundu?

M'maphunziro, tonse timatcha kusinthika kwamitengo ya sapwood blue, yomwe imadziwikanso kuti buluu. Kuphatikiza pa buluu, kumaphatikizaponso kusintha kwa mtundu wina, monga wakuda, pinki, wobiriwira, ndi zina zotero.

2.Incentives for Blue Change

Mitengoyi ikadulidwa, siisamalidwa bwino panthawi yake komanso mogwira mtima. M'malo mwake, mtengo wonsewo umayikidwa mwachindunji pa nthaka yonyowa, ndipo umakhudzidwa ndi mphepo ndi mvula ndi tizilombo toyambitsa matenda. Chinyezi cha nkhuni chikakhala chapamwamba kuposa 20%, malo amkati mwa matabwa amatha kusinthidwa ndi mankhwala, ndipo matabwa amawoneka ngati buluu.

Mapulani opanda kanthu (mapulani oyera opanda mankhwala oletsa kutupa ndi kupenta) amasiyidwanso pamalo onyowa komanso opanda mpweya kwa nthawi yayitali, ndipo adzakhalanso ndi zizindikiro za buluu.

Zomwe zili mu starch ndi monosaccharides mu nkhuni za rabara ndizokwera kwambiri kuposa zamitengo ina, ndipo zimapereka mphamvu zofunikira kuti mabakiteriya a buluu akule. Chifukwa chake matabwa a rabara ndi omwe amakonda kukhala ndi buluu kuposa mitengo ina.

3.Kuopsa kwa kusintha kwa buluu

Mitengo ya buluu ndiyowonongeka kwambiri

Nthawi zambiri, matabwa amapangidwa ndi buluu asanawole. Nthawi zina zimakhala zotheka kuona zolakwika zoonekeratu zowola zomwe zimapangidwira panthawi yamtundu wa buluu. Tinganenenso kuti kusintha kwa mtundu ndi kalambulabwalo wa kuwola.

Discoloration kumawonjezera permeability matabwa

Chifukwa cha kulowa kwa mycelium ya buluu-fungal, timabowo tating'onoting'ono timapangidwa, zomwe zimapangitsa kuti matabwawo asapitirire. The hygroscopicity ya matabwa a blued akaumitsa amachulukitsidwa, ndipo bowa wovunda ndi wosavuta kumera ndikuberekana pambuyo pa kuyamwa chinyezi.

Chepetsani mtengo

Chifukwa cha kusinthika, mawonekedwe a nkhuni sawoneka bwino. Ogwiritsa ntchito nthawi zambiri amakana kuvomereza matabwa kapena matabwa otayika, makamaka omwe amagwiritsidwa ntchito mumitengo yokongoletsera, mipando, ndi madera ena kumene maonekedwe a matabwa ndi ofunika kwambiri, kapena amafuna kuchepetsedwa mtengo. Pazamalonda, kupewa kusinthika kwamitengo ndi gawo lofunikira pakusunga mtengo wamitengo.

4. Kupewa kusinthika kwa buluu

Pambuyo podula mitengo, zipika ziyenera kukonzedwa mwamsanga, mwamsanga zimakhala bwino.

Mitengo yokonzedwayo iyenera kuuma mwamsanga kuti chinyezi chikhale pansi pa 20%.

Sungani nkhuni ndi anti-tarnish agents panthawi yake.
