Kutheni ukhethe ukusebenzisa umqhaphu ofunxa isandi?Ziziphi iimpawu zomqhaphu ofunxa isandi?Masiyazi kunye:
1. Ukufunxa isandi esiphezulu.I-polyester fiberumqhaphu ofunxa isandiyimathiriyeli enemingxuma.Yavavanywa liZiko leAcoustics leYunivesithi yaseTongji.Isiphumo sovavanyo lwemveliso ye-5cm eninzi yi-NRC (I-Coefficient yokuNcitshiswa kweNgxoxo eBanzi): 0.79.Kusekho indawo eninzi yokuphucula ukusebenza;
2. Ukusebenza okugqwesileyo kokusingqongileyo.Ivavanywa liZiko leSizwe loVavanyo lweMpahla yoKwakha kwaye ifikelela kwinqanaba le-E1.Kuvavanywa ukuba inokuqhagamshelana ngokuthe ngqo nolusu lomntu.
3.Ulwakhiwo lubambene kwaye imilo izinzile;
4. Imveliso ayinayo i-formaldehyde kwaye ayinabungozi kumzimba womntu.Ayifaki nayiphi na iglue ngexesha lenkqubo yokubumba kwaye isebenzisa iifiber ezinamaqondo ahlukeneyo okunyibilika ukwenza.Uvavanyo kunye noqheliselo luye lwangqina ukuba aluguquguquki eluswini lomntu, alungcolisi imekobume, kwaye alunavumba.;
5. Ukusebenza kakuhle kokungena kwamanzi, ukukhutshwa kwamanzi okunamandla emva kokuntywiliselwa kwamanzi, ukusebenza kwesandi sokufunxa akunciphi, kwaye imilo ihlala ingatshintshi.
6.Ingasetyenziswa kabini, kulula ukuyitshabalalisa, kwaye akukho ngcoliseko lwesibini kwindalo esingqongileyo.
