Mawonekedwe asanu ndi limodzi a thonje loyamwa mawu

Chifukwa chiyani mwasankha kugwiritsa ntchito thonje loyamwa mawu?Kodi thonje loyamwa mawu ndi chiyani?Tiyeni tidziwe limodzi:

1. Kuchita bwino kwambiri kotengera mawu.Polyester fiberthonje losamva mawundi porous chuma.Idayesedwa ndi Institute of Acoustics ya Tongji University.Zotsatira zoyesa za 5cm wandiweyani ndi NRC (Comprehensive Noise Reduction Coefficient): 0.79.Pali mwayi wambiri wowongolera magwiridwe antchito;

3.Kapangidwe kake ndi kophatikizana ndipo mawonekedwe ake ndi okhazikika;

4. Mankhwalawa alibe formaldehyde ndipo alibe vuto lililonse mthupi la munthu.Simawonjezera guluu panthawi yowumba ndipo imagwiritsa ntchito ulusi wokhala ndi mfundo zosiyanasiyana zosungunuka kupanga.Kuyesera ndi machitidwe atsimikizira kuti ilibe ziwengo pakhungu la munthu, ilibe kuipitsa chilengedwe, ndipo palibe fungo.;

5. Kuchita bwino kwa madzi, ngalande zamphamvu pambuyo pa kumizidwa m'madzi, kuyamwa kwa mawu sikuchepa, ndipo mawonekedwe ake amakhala osasinthika.

6.Zitha kugwiritsidwa ntchito kawiri, ndizosavuta kuwononga, ndipo palibe kuipitsidwa kwachiwiri kwa chilengedwe.
