Kutheni ukhetha ukusebenzisa umqhaphu ofunxa isandi, kwaye zeziphi iimpawu zokusebenza komqhaphu ofunxa isandi?
1. Ukufunxa isandi esiphezulu.Umqhaphu ofunxa isandi kwifiber yepolyester yinto eneporous.Yavavanywa liZiko leAcoustics leYunivesithi yaseTongji.Isiphumo sovavanyo lwemveliso ye-5cm etyebileyo yayiyi-NRC (I-Comprehensive Noise Reduction Coefficient): 0.79.Ukuba ingxinano kunye nobukhulu bonyuswa, yayo Kusekho indawo eninzi yokuphucula ukusebenza;
2. Ukusebenza okugqwesileyo kokusingqongileyo.Kwavavanywa yiZiko leSizwe loVavanyo lweMpahla yoKwakha kwaye yafikelela kwinqanaba le-E1.Uvavanyo kukuba lunokuqhagamshelana ngokuthe ngqo nolusu lomntu;
3. Ulwakhiwo luqinile kwaye imilo izinzile;
4. Imveliso ayinayo i-formaldehyde kwaye ayinabungozi kumzimba womntu.Ayifaki nayiphi na iglue ngexesha lokubumba, kwaye isebenzisa iifiber ezinamaqondo ahlukeneyo okunyibilika ukwenza.Ingqinwe ngovavanyo nangezenzo ukuba ayinakwalana nesikhumba somntu, ayinangcoliso kwendalo, kwaye ayinavumba;
5. Ukusebenza kakuhle kwamanzi, ukukhutshwa kwamanzi okunamandla emva kokucwiliswa kwamanzi, ukusebenza kwesandi sokufunxa akunciphisi, kwaye imilo ihlala ingatshintshi;
I-6.Inokusetyenziswa kabini, kulula ukuyitshabalalisa, kwaye ayinakho ukungcola okwesibini kwindalo.
