Product Details



Wooden soundproof door :
 Wood fireproof sound insulation door panel material: sound-absorbing materials such as rock wool are embedded in the wood frame of the door leaf, and the outer surface is covered with asbestos board, galvanized iron sheet and refractory fiber board, and the gap around the gap is sealed with a sponge rubber strip.
 Sound absorbing material (sound absorbing material): Any material can absorb sound, but the degree of absorption is very different.  A material having an average sound absorption coefficient of more than 0.2 for the above six frequencies is generally classified as a sound absorbing material.  Most of the sound absorbing materials of sound absorbing materials are loose porous materials, such as slag wool, blankets, etc. The sound absorption mechanism is that the sound waves penetrate into the pores of the material, and the pores are mostly open pores that penetrate each other inside, and are subject to friction and viscous resistance of air molecules. And the fine fibers are mechanically vibrated to convert the acoustic energy into heat energy.  The sound absorption coefficient of such a porous sound absorbing material generally increases from low frequency to high frequency, so the sound absorption effect on high frequency and intermediate frequency is better.
 Asbestos board is the abbreviation of asbestos fiber cement board. It is made of asbestos, fiberglass, clay and other materials according to scientific formula.  It has strong tensile strength, withstands pressure and can withstand 1400 °C.
 The refractory board is called high-temperature laminated board of thermosetting resin impregnated paper. The English abbreviation is HPL is the refractory building material for surface decoration. It has rich surface color, texture and special logistics performance. It is widely used in interior decoration, furniture, kitchen cabinet, experiment. Room countertops, exterior walls and other fields.
