ACOUSTIC CEILING PANEL
An acoustical ceiling panel is provided having a core with a front face and a back face composed of air laid mineral fibers and an aqueous binder. The aqueous binder includes a first component in the form of one or more carbohydrates, and a second component in the form of one or more compounds selected from sulfamic acid, derivatives of sulfamic acid, and any salts thereof, ammonia and hypophosphorous acid. A formaldehyde-free first fleece having a thickness is secured to the front face of the core by powdered adhesive and a formaldehyde-free second fleece having a thickness is secured to the back face of the core by the aqueous binder, with the thickness of the first fleece being greater than the thickness of the second fleece. Paint is applied to the first fleece. The acoustical ceiling panel has formaldehyde emissions of below 8 micron g/m2/h of formaldehyde, preferably below 5 micron g/m2/h, most preferably below 3 micron g/m2/h, in accordance with ISO 16000 for testing aldehyde emissions.
提供一种吸音顶棚板，其包括芯部，该芯部具有正面和背面并且包括气流成网式矿物纤维和水性粘合剂。水性粘合剂包括第一组分和第二组分，该第一组分为一种或多种碳水化合物形式，该第二组分为选自氨基磺酸、氨基磺酸衍生物及任何氨基磺酸盐、氨和次磷酸的一种或多种化合物形式。具有一定厚度的无甲醛的第一起绒材料通过粉质胶粘材料固定于芯部的正面，而具有一定厚度的无甲醛的第二起绒材料通过水性粘合剂固定于芯部的背面，其中第一起绒材料的厚度大于第二起绒材料的厚度。将涂料涂覆于第一起绒材料。该吸音顶棚板按照测试甲醛排放量的ISO16000的甲醛排放量低于8μg/m2/h甲醛、优选地低于5μg/m2/h甲醛、最优选地低于3μg/m2/h甲醛。
