Mfundo yotengera mawu ya board-absorbent board imayambitsa

Tsopano ndi chitukuko chosalekeza cha anthu, phokoso lakhala chimodzi mwazinthu zazikulu zowononga chilengedwe, kotero tsopano vuto la malo omangira phokoso ndi chidwi ndi chidwi, sankhani mawu oyenera.board boardpomanga chithandizo cha mayamwidwe amawu ndi njira yomwe imagwiritsidwa ntchito kwambiri pomanga zowongolera phokoso ndi imodzi mwamiyeso yofunikira kwambiri mwaukadaulo.

Kusiyanitsa pakati pa mayamwidwe amtundu wazinthu ndi kusungunula kwa mawu ndikuti mayamwidwe amawu a zinthuzo amayang'ana pa kukula kwa mphamvu yosinthira mawu kumbali ya gwero la mawu, ndipo cholinga chake ndikuwonetsetsa mphamvu ya mawu pang'ono.Kusungunula mawu azinthu kumayang'ana kukula kwa mphamvu yamawu yotumizira mbali ina ya gwero lamawu, ndipo chandamale ndikupangitsa kuti mphamvu yamamvekedwe ikhale yaying'ono.Phokoso mayamwidwe zakuthupi ku zochitika za mphamvu phokoso mayamwidwe, kawirikawiri khumi okha, choncho phokoso mayamwidwe mphamvu yake phokoso mayamwidwe coefficient akhoza kufotokozedwa mu decimal ndi zomveka kutchinjiriza zakuthupi.
Mphamvu yamawu yopatsirana imatha kuchepetsedwa mpaka 10-3 ~ 10-4 yamphamvu yakumveka kapena kuchepera.Kuti mawu amveke bwino, voliyumu yotsekereza mawu imayimiridwa ndi njira yoyezera ma decibel.Zida ziwirizo pakusiyana kwazinthu zimatengera zomwe zidachitika pakuwunikira mphamvu ndizochepa kwambiri, zomwe zikutanthauza kuti mphamvu yamawu ndiyosavuta kulowa komanso kudzera muzinthuzo: mutha kuganiza, zinthuzo ziyenera kukhala porous sulfure komanso kupuma, izi ndi mmene porous phokoso mayamwidwe zakuthupi, nthawi zambiri ndi CHIKWANGWANI, kukoka kapena thovu zinthu kupanga porous dongosolo: kamangidwe kake ndi: zakuthupi ali ndi chiwerengero chachikulu cha, cholumikizira, kuchokera tebulo kuti dzenje, amene ali permeability, pamene phokoso la phokoso limalowa pamtunda wa porous, amachititsa kuti mpweya ukhale wogwedezeka, chifukwa cha kukangana ndi mpweya wokhazikika.
Ma static resistance ndi ma conduction a kutentha amasintha gawo lalikulu la mphamvu yamawu kukhala mphamvu ya kutentha, motero amasewerera mayamwidwe amawu.Pakuti phokoso kutchinjiriza zakuthupi, kufooketsa kufala kwa mphamvu phokoso, kutchinga kufalikira kwa phokoso, si porous monga phokoso mayamwidwe zakuthupi, porous, mpweya, m'malo mwake, zinthu zake ziyenera kukhala zolemera ndi wandiweyani, monga mbale zitsulo, kutsogolera. mbale, khoma la njerwa ndi zipangizo zina.Kufunika kwa zida zopangira mawu ndi wandiweyani popanda pores kapena mipata: pali cholemetsa chachikulu, chifukwa chamtundu woterewu ndi wandiweyani, ndizovuta kuyamwa ndikudutsa mphamvu yamawu ndikuwonetsa kuchokera ngakhale, kotero kuti mayamwidwe ake amamveka bwino. si zabwino.
Mu uinjiniya, cholinga ndi kutsindika kwa mayamwidwe amawu komanso kutulutsa mawu kumasiyana.Cholinga cha chithandizo cha mayamwidwe a phokoso ndi kuchepetsa kubwereza mobwerezabwereza kwa phokoso, ndiko kuti, kuchepetsa nthawi yosakanikirana ya phokoso, ndipo phokoso lopitirira limachepetsedwa pakuchepetsa phokoso lamkati, lomwe liri m'nyumba yomweyi. danga la gwero la mawu ndi zinthu zokomera mawu.Ndipo pamawu omwe amachokera kuchipinda choyandikana nawo, zida zoyamwitsa zomveka zimagwiranso ntchito, zomwe zimafanana ndi kuwongolera kuchuluka kwa mawu amtundu wa envelopu.
