[0031] like Figures 1 to 5 As shown, an embodiment of this disclosure provides a cleanroom soundproofing panel 100, which includes a soundproofing substrate 10 and a fixing member 20. The soundproofing substrate 10 includes a soundproofing layer 11 and a dustproof layer 14. The fixing member 20 has a receiving space, and the soundproofing substrate 10 is fixed in the receiving space. The fixing member 20 includes a fixing area 222, and the fixing area 222 is provided with a plurality of through holes 2221. The dustproof layer 14 is located between the soundproofing layer 11 and the fixing area 222. The surface of the fixing member 20 is coated with an antistatic coating 201.
[0032] According to the clean sound-absorbing panel 100 of the present disclosure, the fixing member 20 fixes the sound-absorbing panel 10 in the accommodating space thereof to prevent the sound-absorbing panel 10 from being damaged. The fixing area 222 of the fixing member 20 is provided with a plurality of through holes 2221, through which noise can directly enter the accommodating space of the fixing member 20 and be absorbed by the sound-absorbing panel 10 in the accommodating space. The provision of the through holes 2221 can reduce the obstruction of the fixing member 20 to the propagation of noise, so that more noise enters the accommodating space and is absorbed by the sound-absorbing panel 10, thereby improving the noise absorption rate of the clean sound-absorbing panel 10. In addition, the sound-absorbing panel 10 comprises the sound-absorbing layer 11 and the dustproof layer 14, wherein the dustproof layer 14 is located between the sound-absorbing layer 11 and the fixing area 222, and the dustproof layer 14 is used to isolate the through holes 2221 of the fixing area 222 from the sound-absorbing layer 11, so as to prevent the particles or dust falling from the sound-absorbing panel 10 in the accommodating space from entering the clean room through the through holes 2221, avoid the sound-absorbing panel 10 from polluting the clean room, and ensure the cleanliness of the clean room. The surface of the fixing member 20 is coated with an anti-static coating 201, and the provision of the anti-static coating 201 can prevent static electricity from being generated on the surface of the clean sound-absorbing panel 10, avoid the static electricity generated by the clean sound-absorbing panel 10 from attracting small particles, dust and the like in the air of the clean room, and ensure the cleanliness of the clean room.
[0033] In some embodiments of the present disclosure, the resistivity of the anti-static coating 201 ranges from 10 6 ~ 10 9 Ω·m, and the anti-static coating 201 can play a good anti-static effect in this resistivity range. The anti-static coating 201 does not affect the sound-absorbing effect of the sound-absorbing layer 11. The material of the anti-static coating 201 can be formed by adding conductive fillers such as carbon black, graphene and metal powder in a polymer matrix. The material of the anti-static coating 201 can also be formed by mixing conventional coatings in antistatic agents such as quaternary ammonium salt compounds and ethoxylated fatty amines. The material of the anti-static coating 201 can also be made of metal oxide materials such as indium tin oxide and zinc oxide.
[0034] In some embodiments of the present disclosure, the material of the dustproof layer 14 can be dustproof cloth, polyester fiber cloth, glass fiber cloth and the like, which can all play a dustproof role and will not hinder the sound-absorbing effect of the sound-absorbing layer 11. The material of the dustproof layer 14 can also be other materials that can play a dustproof role and will not hinder the sound-absorbing effect of the sound-absorbing layer 11. The thickness of the dustproof layer 14 in the present embodiment is much smaller than the thickness of the sound-absorbing layer 11, and the thickness of the dustproof layer 14 will not hinder the sound-absorbing effect of the sound-absorbing layer 11.
[0035] As Figures 2 to 5As shown, in some embodiments of this disclosure, the fixing member 20 includes a first housing 22, a support frame 21, and a second housing 23 connected in sequence. That is, the two ends of the support frame 21 are respectively connected to the first housing 22 and the second housing 23, and the first housing 22, the support frame 21, and the second housing 23 form a receiving space that can accommodate the sound-absorbing substrate 10. The sound-absorbing substrate 10 is fixed in the receiving space to fix the sound-absorbing substrate 10, prevent the sound-absorbing substrate 10 from moving in the fixing member 20, and improve the reliability and service life of the clean sound-absorbing plate 100.
[0036] The surfaces of the first housing 22 and the second housing 23 are respectively coated with an antistatic coating 201. The antistatic coating 201 can prevent the generation of static electricity on the surfaces of the first housing 22 and the second housing 23, and avoid the static electricity generated by the cleanroom sound-absorbing plate 10 from attracting tiny particles, dust and other particles in the cleanroom air, thus ensuring the cleanliness of the cleanroom.
[0037] The first housing 22 includes a connecting area 221 and a fixing area 222. The connecting area 221 connects the fixing area 222 and the support frame 21 to achieve the connection between the first housing 22 and the support frame 21. When the cleanroom sound-absorbing plate 100 is applied, the fixing area 222 is located on the side of the cleanroom sound-absorbing plate 100 closer to the noise source. Multiple through holes 2221 are provided in the fixing area 222, allowing noise to directly enter the receiving space of the fixing member 20 through the through holes 2221 and be absorbed by the sound-absorbing substrate 10 within the receiving space. The arrangement of the through holes 2221 can reduce the obstruction of noise transmission by the first housing 22, allowing more noise to enter the receiving space and be absorbed by the sound-absorbing substrate 10, thereby improving the noise absorption rate of the cleanroom sound-absorbing plate 10.
[0038] like Figure 1 As shown, in some embodiments of this disclosure, the connecting area 221 is arranged around the fixing area 222 in a ring shape along the circumference of the fixing area 222. The connecting area 221 is connected to the support frame 21, and the fixing area 222 is connected to the support frame 21 through the connecting area 221. The connecting area 221 may be a ring-shaped plate structure or a ring-shaped arrangement of multiple plates.

[0040] In some embodiments of this disclosure, the fixed area 222 has multiple through holes 2221, which are evenly distributed throughout the fixed area 222. These multiple through holes 2221 allow more noise to directly enter the accommodating space, reducing the noise barrier effect of the first housing 22.

The thickness of the sound-absorbing layer 11 is the largest among other layers of the sound-absorbing substrate 10, so as to ensure that the sound-absorbing substrate 10 has excellent sound-absorbing or sound-isolating effect. The sound-absorbing layer 11 is further provided with mounting grooves arranged in a closed annular shape along the circumference of the sound-absorbing layer 11. When the clean sound-absorbing plate 100 is installed, the mounting grooves of the circumferential layer of the clean sound-absorbing plate 100 can be matched with the keel, and the clean sound-absorbing plate 100 can be fixed on the keel through screws or rivets; or according to the needs, the clean sound-absorbing plate 100 can be installed at the position where sound-absorbing is needed through the mounting grooves.
