浙江省科委、城乡建设厅、建材工业总公司于今年5月联合召开了建筑拒水粉应用推广会。省内有关建筑、建材工业的科研、设计、施工、教学、管理等方面的科技、管理人员参加了会议,听了余姚市防水材料二厂和同济大学代表作的建筑拒水粉的研制及推广报告,并考察了应用施工现场,经讨论提出了推广设想。建筑拒水粉是一种新型的粉剂防水材料,它由脂肪酸、氢氧化钙等为原料,以特定工艺制成浆体,再经脱水等处理,形成复合的特种聚集状态的粉末,该粉末的外层是憎水的脂肪酸钙。建筑拒水粉的防水机理完全不同于传统的防水材料,它是靠粉末的聚集、堆积而构成防水层,粉末的憎水性赋予防水层
The Zhejiang Provincial Science and Technology Commission, the Urban and Rural Development Department and the Building Material Industry Corporation jointly held the Construction Water Repellent Powder Application Promotion Conference in May this year. The science and technology and management personnel in the province’s scientific research, design, construction, teaching, and management related to the construction and building materials industries attended the meeting and heard reports on the development and promotion of building water-repellent powders from Yuyao Waterproof Material Factory and Tongji University. And examined the application of the construction site, after discussion and promotion ideas. Building water-repellent powder is a new kind of powder waterproof material. It is made of fatty acid, calcium hydroxide, etc. as a raw material, made into a slurry by a specific process, and then treated by dehydration to form a composite special aggregate powder, outside of the powder. The layer is hydrophobic fatty acid calcium. The water-repellent mechanism of building water-repellent powder is completely different from the traditional waterproof material. It consists of the accumulation and accumulation of powder to form a waterproof layer, and the water repellency of the powder gives the waterproof layer.
