Matanhatu ekuita maitiro ekotoni inotora ruzha iwe unofanirwa kuchengeta mupfungwa

Sei uchisarudza kushandisa donje rinotora inzwi, uye ndeapi maitiro ekuita kwedonje rinotora inzwi?

1. Kubata kwepamusoro-soro kunobata.Polyester faibha mutsindo-inotora donje chinhu chine porous.Yakaedzwa neInstitute of Acoustics yeTongji University.Mhedzisiro yebvunzo ye5cm gobvu chigadzirwa yaive NRC (Comprehensive Noise Reduction Coefficient): 0.79.Kana iyo density uye ukobvu zvichiwedzerwa, its Kuchine nzvimbo yakawanda yekuvandudza kwekuita;

2. Kuita kwakanakisa kwezvakatipoteredza.Yakaedzwa neNational Building Materials Testing Center uye yakasvika E1 level.Kuongorora ndeyekuti inogona kubata zvakananga ganda remunhu;

3. Chimiro chacho chakabatana uye chimiro chakagadzikana;

4. Chigadzirwa chacho hachina formaldehyde uye hachina ngozi kumuviri wemunhu.Iyo haiwedzeri chero glue panguva yekuumbwa, uye inoshandisa mafiber ane akasiyana mapoinzi ekunyungudika kuti aumbe.Kwakabvumikiswa nemiedzo netsika kuti harina allergies paganda romunhu, harina kushatisa mhoteredzo, uye harina hwema;

5. Kushanda kwakanaka kwemvura, mvura yakasimba mushure mekunyudzwa kwemvura, kushanda kwekunzwa kwenzwi hakuderera, uye chimiro chinoramba chisina kuchinja;

6.Inogona kushandiswa kaviri, nyore kuparadza, uye haina kusvibiswa kwechipiri kune zvakatipoteredza.
