这类板材,其重量的2—6％为纤维素浆液(自由度100—200毫升),10—40％是空心珍珠岩小珠(平均直径≤200微米),其余的为水硬性水泥、增强纤维、填料。例如,用纤维素浆液(自由度188毫升) 5％,维尼纶0.7％,珍珠岩小珠30％,微粒硅灰石10％,波特兰水泥54.3％制成混合料,经压制成型,在80℃条件下养护3天并干燥。所得板材的抗弯强度为102千克/厘米~2,尺寸稳定性能好,不燃。
This type of board, its weight of 2-6% for the cellulose slurry (degrees of freedom 100-200 ml), 10-40% of the hollow perlite beads (average diameter ≤ 200 microns), the rest of the hydraulic cement, enhanced Fibers, fillers. For example, a mixture of cellulose slurry (with a degree of freedom of 188 ml) 5%, vinylon 0.7%, perlite beads 30%, particulate wollastonite 10%, portland cement 54.3%, was formed into a mixture and subjected to compression molding. The mixture was cured at 80°C for 3 days and dried. The obtained sheet has a bending strength of 102 kg/cm~2, good dimensional stability, and non-flammability.
