Introduction to pyramid
Pyramid cotton is one of the kind of sound-absorbing cotton, pyramid cotton has a beautiful appearance and good acoustic characteristics, it is characterized by: because of its four-cone shape, it also provides a little spread, which will make your voice more Have vitality. Pyramid is made of polyester sponge material through a unique device to form a square cone-shaped sound-absorbing cotton. After the complex foam formed after the sound insulation, silencing, sound absorption, reduce the vibration of the sponge material. Its pyramid cotton filled with subtle voids and semi-open structure so that it can absorb the sound of the sound into the sound attenuation effect, reduce the sound waves in the indoor reflection of the interference and echo, to maintain the purity of the sound: noise absorption Materials of high-performance products.
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!
金字塔棉吸音原理
影响海绵吸音效果的主要原因是产品厚度、产品密度和里外空气流阻等。空气流阻是单位厚度时材料两侧空气气压和空气流速之比。空气流阻是影响海绵吸音隔音性能的重要原因。流阻太小，说明材料稀疏，空气振动容易穿过，吸声性能下降；流阻太大说明材料密实，空气振动难于传入，吸音性能下降。海绵具有很多内外联通孔隙和气泡，当声波入射到波浪其中时，可引起空隙中空气振动由于空气的粘滞阻力，空气与孔壁的摩擦，使很大一部分声能转化成热能而被消耗，加上海绵的凹凸波浪形状，让剩余的声波在凹凸反复的折射逐渐减少。此外当空气绝热压缩时，空气与孔壁之间不断发生热交换，由于执导作用，也会使一部分声能转化成热能，从而达到吸音的效果！吸音的效果跟开孔的大小还有整张棉的厚度有着重要的关系，太薄的话即使能吸音也只能吸一小部分的，另外开孔不适合开过大，过大就会没有吸音效果，过小阻力太大声音过不去，因为在声音经过吸音棉的时候会跟吸音棉产生摩擦，会把原有的声音的动作缓冲了一下，会减低原来声音的穿透力，从而对隔音来说还是有辅助效果的，但隔音还得用专业的隔音棉较为理想！
Pyramid cotton use
The sponge is non-toxic, tasteless, environmentally friendly, is the ideal indoor noise / sound absorption, audio reflective material; widely used in recording studio, studio, video room, audiovisual room, drum room, KTV, sound studio, Room, audition room, acoustic laboratory, conference room, studio, theater and other occasions, interior decoration, as well as the engine room silencer, generator silencers, speakers and other sound-absorbing silencer use.
Thickness and density: pyramid cotton thickness is conventional 5cm. With the change in the thickness and density of the pyramid of cotton, the sound absorbing effect of the pyramid cotton is proportional to the thickness and density of the pyramid. Select the density of the time according to the actual use of choice.
金字塔棉用途
该海绵无毒、无味、环保卫生，是理想的室内隔音/吸音、音频反射材料；广泛应用于录音棚、录音室、影音室、视听室、鼓房、KTV，测音室、语音室、播音室、试音室、声学试验室，会议厅、演播厅、影剧院等场合的室内装饰，以及机房消音、发电机组消音、音箱等吸音消音场所使用。
厚度和密度：金字塔棉的厚度常规是5cm。随着金字塔棉的吸音厚度和密度的变化，金字塔棉的吸音效果与金字塔棉的厚度和密度成正比。选择密度的时候可根据实际用途选择。
Pyramid cotton installed
1, the glue were evenly coated on the back of the sound-absorbing cotton and the wall, and so on 80% of the dry glue, the sponge up, a little hard to press.
2, with a strong adhesive double-sided adhesive, attached to the cotton, the cotton paste on the wall can be pressed flat.
3, nail directly on the wall (note the size of the nail head).
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）。
