Detail
Parameters
The main material is basalt sound-absorbing cotton. The basalt noise reduction board composed of it and the installation outer box is installed outside the high-voltage transformer. The noise reduction performance is up to more than 12dB, which is significantly improved compared with the traditional noise reduction treatment.
Product features
It has noise reduction effect on noise within 20kHz, and significantly reduces noise from 200Hz to 2500Hz.
With the increase of noise, the noise reduction effect is more obvious.
Product performance
Bulk density: (30 ~ 50) kg / m3;
Noise reduction performance (90mm): ≥ 10dB;
Thermal conductivity: ≤ 0.035w / (m · K);
Flame retardant: grade B1;

Basalt fiber
Basalt fiber is one of the four key high-tech fibers developed in China. It is a continuous fiber drawn by platinum rhodium alloy drawing leakage plate at high speed. It is a new inorganic environmental protection and green fiber material.
Basalt fiber Twistless Yarn
Basalt fiber untwisted yarn is a basalt fiber product composed of multi strand parallel precursor or single strand parallel precursor without twisting, which is divided into inward retreat and outward retreat products.
Basalt fiber chopped yarn
It is short cut from the corresponding basalt fiber substrate. It has good dispersion, high temperature stability, low temperature crack resistance, fatigue resistance and antistatic properties.
