硫氧镁板的浆体滤液pH值波动在8~9.5之间,接近于中性,对玻璃纤维和木质纤维的腐蚀性是很小。大家知道GRC制品以玻璃纤维增强,植纤制品以锯末,刨花、棉秆、蔗渣、花生壳、稻壳、玉米心粉等木质纤维下脚料增强,硫氧镁保温板原料而玻璃纤维和木质纤维都是不耐碱的材料,极其怕碱腐蚀,在高碱腐蚀下它们都会失去强度,对胶凝材料失去增强作用。
The pH value of the slurry filtrate fluctuated between 8 and 9.5, which was close to neutral, and had little corrosiveness to glass fiber and wood fiber. As we all know, GRC products are reinforced by glass fiber, and plant fiber products are reinforced by sawdust, wood fiber scraps such as shavings, cotton stalks, bagasse, peanut shells, rice husks, corn flour, etc. the raw materials of Sox insulation board, glass fiber and wood fiber are all alkali resistant materials, extremely afraid of alkali corrosion, they will lose strength and strengthen cementitious materials under high alkali corrosion.
所以,常规水泥因高碱就无法用玻纤及木质纤维增强。而镁水泥却以独特的微碱性优势,在GRC领域和植纤制品领域大显身手。轻质低JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 密度硫氧镁保温板的密度一般只有普通硅酸盐水泥制品的70%,它的制品密度一般为1600~1800㎏/m3,而水泥制品的密度一般为2400~2500㎏/m3。因此它具有十分明显的低密度性。
Therefore, conventional cement cannot be reinforced with glass fiber and wood fiber due to its high alkali content. However, magnesium cement, with its unique advantages of micro alkalinity, plays an important role in the field of GRC and fiber products. The density of light low density magnesium oxysulfide insulation board is generally only 70% of that of ordinary portland cement products. Its product density is generally 1600-1800 kg / m3, while the density of cement products is generally 2400-2500 kg / m3. So it has very obvious low density.
