Soundproof door for insulating external noise
The invention discloses a soundproof door for insulating external noise. The soundproof door comprises an inner door plate and an outer door plate which formed through welding. The soundproof door isfilled with a gypsum board, a silicate board, keels and glass wool, a silicate board and a gypsum board in sequence from the inner door plate to the outer door plate. The inner door plate and the outer door plate are both cold-rolled plates made of high-quality carbon steel. In the soundproof door, by means of the high-quality carbon steel and the reasonably-designed inner filler, the sound reduction index of the product reaches 51 dB, and the problem that large factories and laboratories are high in noise is solved.
本发明公开了一种用于外部噪音隔断的隔声门，包括焊接而成的内门板和外门板，所述隔声门内部，从内门板至外门板依次填充石膏板、硅酸盐板、龙骨与玻璃棉、硅酸盐板、石膏板，内门板与外门板均为优质碳钢材质的冷轧板。本发明中，采用优质碳钢和合理设计的内部填充物，使产品的隔声量达到51dB，解决了大型工厂以及实验室噪音过大的问题。
