Pali mitundu iwiri ya siling'ono m'makampani: denga lowonekera ndi denga lobisika.

1.Mtundu wa chimango chowonekera: keel yomwe imatha kuwonedwa bwino kuchokera kunja;

2.Mtundu wobisika wa chimango: sichiwoneka mosavuta kuchokera pamawonekedwe ndipo nthawi zambiri zida zopepuka zapadenga zimatha kukhazikitsidwa.Siling'ono zobisika, monga mineral fiberboard board ndi fiberglass board, palinso mtundu wina woyimitsidwa wobisika, womwe umagwiritsa ntchito keel yachitsulo chopepuka, monga pulasitala kapena denga lalikulu lopanda msoko.

Tengani fiberglass bolodi mwachitsanzo, tiyeni tione ubwino wake.Fiber glass board yobisika ikuwoneka chonchi.Kugwiritsa ntchito mapanelo obisika kungapangitse malo kukhala okongola komanso aukhondo.Simudzawona denga lililonse kuchokera kunja.Denga lobisika silifuna mbiri yochulukirapo kuti lithandizire, limatha kudzithandizira palokha.Uwu ndiye mwayi waukulu kwambiri wa denga lobisika, ngakhale mtengo wake ndi wokwera pang'ono kuposa denga wamba, koma ndizochita zenizeni.

Magalasi opangira magalasi acoustic ali ndi zinthu zotsatirazi.

1. Anti-fouling: Pamwamba pa denga la galasi lotsekemera phokoso la galasi limagwiritsidwa ntchito ndi njira yapadera, yosalala, yopanda madzi, komanso yosavuta kusonkhanitsa fumbi.Ngati pali dothi pamtunda chifukwa cha zinthu zakunja, mutha kugwiritsa ntchito nsalu yonyowa kapena chofufutira kuti muchotse dothi.

2. Chinyezi-umboni: The zopangira kukonzedwa ndi luso youma njira.Ulusiwo umapopedwa ndi centrifuge ndipo amapangidwa mwachindunji ndi makina osindikizira apamwamba.Ulusiwo si hydrophilic.Ngakhale pali pores ambiri muzinthuzi, zinthuzo sizingakhudzidwe ndi chilengedwe cha chinyezi.Deformation, sag, kutupa, kupindika, warping ndi zina zochepa quadrants amapangidwa.Mayesero angapo atsimikizira kuti mankhwalawa atha kugwiritsidwa ntchito m'malo ovuta kwambiri okhala ndi kutentha kwambiri komanso chinyezi chambiri ndikusungabe magwiridwe antchito ndikukwaniritsa zofunikira zazinthu zoteteza chinyezi.
