时间:2016-01-06     作者:华东公司【原创】   阅读

外墙保温砂浆是以无机胶凝剂、有机胶凝剂、填料、集料与添加剂等原料按科学配比、精确计量和工业化生产制成的多品种、多用途干混粉体。在施工现场只需加入一定量的水,经均匀混合即可使用。主要特点是:高度节能、绿色环保、施工方便、便于存储。外墙保温干粉砂浆在国外发达国家早已开始应用,在欧洲及美国从20世纪70年代初期就已经淘汰传统砂浆而采用高节能环保型干粉砂浆。30多年来,在欧美发达国家的使用面积已经超过8亿平方米。在韩国、日本、新加坡等东南亚国家和地区都有广泛应用。干粉砂浆在我国内地应用尚处于起步阶段,随着我国建筑技术的发展,对施工效率和质量要求的提高,国家已经认识到干粉砂浆在未来中国市场上的前景和价值,并将它列为重点开发和鼓励的15个项目之一。干粉砂浆之所以在全世界及中国得到认可,并取代传统砂浆而广泛应用,主要原因有两点:

Exterior insulation dry powder mortar is the inorganic gelling agent, organic gelling agent, filler, ratio of raw materials such as aggregate and additives scientifically, accurate measurement and industrialized production of many varieties, multi-purpose dry mixing powders. In the construction site need to add a certain amount of water, can be used by mixing. The main features are: high energy saving, green environmental protection, construction is convenient, easy to store. Exterior insulation dry mortar is already used in foreign developed countries, in Europe and the United States since the early 1970 s has been eliminated traditional mortar and high energy efficient and environmentally friendly dry mortar. More than 30 years, the use of the developed countries in Europe and the United States has more than 800 million square meters. In South Korea, Japan, Singapore and other southeast Asian countries and regions have a wide range of applications. Dry mortar application in the mainland is still in its infancy, with the development of construction technology in China, the improvement of efficiency and quality of construction, countries have recognized dry mortar in the future the prospects of the Chinese market and value, and put it as one of the key development and encouraging the 15 items. Dry mortar is recognized around the world and China, and widely used instead of traditional mortar, there are two main reasons:

 

(一)质量优良,施工方便,符合现代建筑质量要求。

(a) the quality is good, construction is convenient, conform to the requirements of the quality of modern architecture.

干粉砂浆比传统预拌(湿)砂浆在各方面的质量性能都有很大提高。传统砂浆为现场拌制型产品,计量准确性难以控制,导致质量波动。此外传统砂浆原料性质单一,在凝结硬化过程中,水分蒸发形成较多的孔隙。同时水泥基硬化体与聚苯板的收缩性能差异较大,因而在聚苯板和砂浆粘结的界面不均匀地分布着较高应力,该应力处于热力学的不稳定状态,趋向于自发地均匀分布,这种作用以及在外界的作用下,经常出现墙体开裂、渗水、及抹灰层空膨、脱落等现象,无法满足现代新型建筑材料对砂浆的不同要求。干粉砂浆是通过聚合物的引入改善了界面状态和胶黏剂本身的柔性。性能优良、功能齐全,可根据不同的使用要求,生产出不同种类的产品。计量准确,有效保证了质量,且干粉砂浆通过集中生产、分散销售方式,有效解决了工地现场拌制存在的质量不稳定和脏、乱等各种弊端,更加便于文明施工。从这方面看干粉砂浆以其优良的质量、便捷的施工特点,取代传统砂浆是国家建筑节能要求及建筑质量控制的必然选择。

Compared with the conventional ready-mixed mortar powder (wet) mortar has greatly improved in all aspects of the quality performance. Traditional mortar mixing type products at site, the measuring accuracy is hard to control, cause the quality fluctuation. In addition to traditional mortar properties of single raw materials, in the process of condensation sclerosis, moisture evaporates more pore space. At the same time, the shrinkage of cement hardening body with polystyrene board performance difference is bigger, therefore in polystyrene and mortar bonding interface is not evenly distributed with high stress, the stress in the thermodynamic state of instability, tend to spontaneously uniform distribution, the effect and under the action of the outside world, often in the wall cracks, water seepage, and floated coat empty, fall off wait for a phenomenon, unable to meet the requirements of modern new building materials for mortar. Dry mortar is through the introduction of the polymer itself to improve the interface state and adhesives of flexible. Excellent performance, complete functions, can be used according to different requirements, produce different kinds of products. Measuring accurately, effectively ensure the quality, and by focusing on the production of dry mortar, dispersed the sales way, effectively solve the quality of the mixing exists on a project site instability and dirty, all sorts of drawbacks, such as more civilized construction. In terms of the dry powder mortar with its excellent quality, convenient construction characteristics, instead of traditional cement mortar is national building energy-saving requirements and the inevitable choice of construction quality control.

(二)符合国家节约能源政策即建筑节能标准与法规。

(2) comply with the national energy conservation policy is building energy efficiency standards and regulations.

根据我国能源的实际情况在“十五”计划和2015年规划中已明确提出“开发和节约并重,并把节约放在优先地位,对国民经济实行以节约为中心的技术改革和结构改革”的能源工作方针,《公共建筑节能设计标准》的正式实施,标志着我国建筑节能工作在民用建筑领域全面铺开,是大力发展节能型建筑、强制推行建筑节能的一项重大举措。《标准》的出台,表明了国家对建筑节能的重视,对降低能耗的决心。我国建筑节能的标准是,到2010年全国城镇建筑的总耗能要实现节能50%,到2020年全社会建筑的总能耗达到节能65%.发展外墙保温技术及合理应用保温墙体材料,是实现建筑节能的主要方式。其中外墙保温因其保温效果好、施工方便、综合投资低、使用范围广、可有效保护建筑主体结构等优点,成为目前大力推广的一种建筑保温节能技术,是墙体保温的主要形式。

According to the actual situation of our country energy in the tenth five-year plan and 2015 planning has clearly put forward "paying equal attention to development and conservation, and give priority to conservation, implements to save for the national economy as the center of technology reform and structure reform" of energy policy, the formal implementation of the "public building energy efficiency design standard", marked the our country building energy efficiency work carried out in the field of civil construction, is to vigorously develop energy-saving building, impose a significant act of building energy efficiency. "Standard", shows that the country's emphasis on building energy efficiency, to reduce energy consumption. Is our country's building energy efficiency standards, by 2010 the urban construction of the total energy consumption to achieve energy saving 50%, to 2020, the whole society building energy-saving 65% of total energy consumption of exterior wall thermal insulation technology development and reasonable application of thermal insulation wall materials, is the main way to realize building energy efficiency. Of exterior wall thermal insulation owing to its good heat preservation effect, convenient construction, low comprehensive investment, wide range of use, which can effectively protect the advantages of the main structure construction, is now promoting a building heat preservation and heat insulation technology, is the main form of the wall heat preservation.

目前我国使用的传统预拌(湿)砂浆,约有15%~20%的材料损耗,而干粉砂浆为薄层施工,比传统砂浆节约用料60%左右,既节省材料及存储费用,又提高建筑使用寿命,还节省后期维修费用。由此看来干粉砂浆作为高节能型产品、建筑节能的最佳系统产品,它的普及应用已是必然之事。
