| 聚乙烯醇粉末（2488）使用方法 Polyvinyl alcohol powder (2488) method 聚乙烯醇粉末（2488）是特别适合作建筑砂浆添加剂，跟纤维素醚类保水剂配合使用，他们改善水泥砂浆及石膏建材的柔韧性，保水性，提高砂浆的黏度。另外，它们能减少砂浆的摩擦，从而增强工作效能及质量。（防止抹灰层的开裂，脱落，增加其附着强度和平滑性。）聚乙烯醇粉末的粘接强度比可再分散性乳胶粉高出2.5-3倍，运用先进超低温加工工艺，生产的产品细度均匀，溶解性好，腻子，砂浆中利用率极高，大大降低生产成本。 Poly (vinyl alcohol) (2488) is especially suitable for building mortar powder additives, used together with cellulose ethers water retention agent, they improve the cement mortar and the flexibility of gesso building materials, water retention, improve the slurry viscosity. In addition, they can reduce the friction of mortar, thus enhancing work efficiency and quality. (to prevent cracking of the plaster layer, shedding, increasing its adhesion strength and smoothness.) Polyvinyl alcohol powder bonding strength than to 2.5 3 times higher dispersion of emulsion powder, using advanced cryogenic process, the production of the product fineness uniformity, good solubility, putty, utilization rate is extremely high in the mortar, greatly reduce the production cost. |
