膨胀珍珠岩装饰吸声板及其制造工艺
Expanded perlite decorative acoustic board and its manufacturing process
多功能膨胀珍珠岩装饰吸声板及其制造工艺,它是对珍珠岩矿石进行分色,进行单独膨化,加入氟硅酸、水玻璃,然后加压、干燥制成的产品,表面美观,从生产到安装成品率达99%,500×500×15mm的断裂荷载达25—100kg,表面不脱粉。
Multi-function expanded perlite decorative acoustic board and its manufacturing process, it is to color separation of perlite ore, the separate puffing, join fluosilicic acid, sodium silicate, and products made of compression, drying, surface appearance, from production to installation yield was 99%, and the fracture load of 500 x 500 x 15 mm up to 25, 100 kg, not to take off on the surface of powder.
多功能膨胀珍珠岩装饰吸声板,其配比为(重量百分组成):膨胀珍珠岩45-51%,水玻璃45-51%,氟硅酸钠3-5%,制备工艺为:(1)对珍珠岩矿石进行分色选,选同样色泽的一起加工,(2)对同样色泽的珍珠岩进行单独膨化,(3)对膨胀珍珠岩进行筛选,(4)将氟硅酸加水稀释,然后加入水玻璃中搅拌,(5)将3、4两种料加在一起搅匀,然后加压至20MPa,干燥温度由20℃升至400 ℃,然后再降温至20℃,时间为37小时。
Multifunctional expanded perlite decorative acoustic board, its ratio is (weight percentage composition) : 45-51% expanded perlite, 45-51% sodium silicate, sodium fluosilicate by 3-5%, of perlite ore preparation process is: (1) color choose, choose the same color together processing, (2) of the same colour and lustre of individually expanded perlite, (3) screening of expanded perlite, water (4) fluosilicate, then stir in sodium silicate, (5) 3, 4, two kinds of materials together stir, then pressurized to 20 mpa, drying temperature from 20 ℃ to 400 ℃, and then cooled to 20 ℃, time of 37 hours.
