金字塔棉简介
 
金字塔棉是吸音棉的其中一种，金字塔棉有美观的外观和良好的声学特性，它的特点是：由于它的四菱锥外形，它还提供了一点扩散，这会让你的声音更加的有活力。金字塔棉是采用聚酯海绵材料经过独特的设备处理形成的一面方锥形状的吸音棉。经过复杂发泡以后形成的隔音、消音、吸音、减少震动的海绵材料。其金字塔棉充满细微的空隙及半开孔结构让其能更大的吸收射入的声波量起到声波衰减效果，降低声波在室内反射声的干扰和回声，保持声音的纯度：是吸音降噪材料的高性能产品。

Pyramid cotton sound - absorbing principle The main reason for the effect of sponge sound absorption is product thickness, product density and inside and outside the air flow resistance and so on. The air flow resistance is the ratio of the air pressure and the air flow rate on both sides of the material at the unit thickness. Air flow resistance is an important reason for the sound insulation performance of sponge. Flow resistance is too small, indicating that the material sparse, easy to pass through the air vibration, sound absorption performance; flow resistance is too large that the material is dense, air vibration is difficult to pass in, sound performance decreased. Sponge with a lot of internal and external Unicom pores and bubbles, when the sound waves into the waves which can cause air in the air vibration due to air viscosity resistance, air and hole wall friction, so that a large part of the sound energy into heat and be consumed, Plus the sponge of the convex wave shape, so that the remaining sound waves in the repeated refraction of the gradual reduction. In addition, when the air adiabatic compression, the air and the hole wall between the continuous heat exchange, due to the role of guidance, will make part of the sound energy into heat, so as to achieve the effect of sound absorption! The effect of sound absorption with the size of the hole there is the thickness of the whole cotton has an important relationship, too thin, then even if the sound can only absorb a small part of the other openings are not suitable for too large, too large will not sound Effect, too little resistance too much sound too hard, because the sound through the sound-absorbing cotton when the friction with the cotton will produce friction, the action will be the original sound buffer a bit, will reduce the penetration of the original sound, so the sound That still have a secondary effect, but the noise had to use a professional sound insulation cotton is more ideal!

金字塔棉安装
 1、把胶水分别均匀涂在吸音棉的背面和墙上，等胶水八成干的时候，把海绵平铺上去，稍微用力按压即可。
 2、用粘性比较强的双面胶胶，贴在棉上，将棉贴在墙上压紧按平即可。
 3、直接用钉子钉在墙上（注意钉子头部大小）。
