3、可以应用于α、β半水石膏及硬石膏粉中,减水率大,增强效果非常明显。掺量为石膏粉重量的0.5~1.2%。改善石膏浆体的塑性粘度,同时可提高石膏制品的表观光洁度、耐久性、抗磨性等。配制高强石膏、石膏制品的流动性、抗压强度、抗折强度、抗渗性、表面光洁度和弹性均有改善,使石膏模具周转率增加4~5倍。
4、适于配制商品混凝土、泵送混凝土、流态砼、高强高性能混凝土、免振捣自密实混凝土、蒸养砼,高强砂浆。
5、适于配制耐火混凝土、蒸养混凝土、清水混凝土、装饰混凝土,彩色砼。
6、可以作为防水材料的主要组分,提高混凝土或砂浆的抗渗能力。也可以与UEA等材料作为混凝土的组分配制结构自防水混凝土。
7、作为油井水泥的高效分散剂应用于油井固井工程中。本产品已在大庆油田得到广泛应用。
8、制品塑面光亮、光滑、坚硬耐磨、花纹清晰,红、黄、绿等各种色彩都鲜亮、持久如新。
9、三聚氰胺高效减水剂的颜色为白色,不引气,因此适合于清水混凝土。
10、三聚氰胺在低温下也无沉淀产生,有利于冬季施工。
11、三聚氰胺在提高早期强度以及无加气性使其在预制混凝土方面应用比较理想,适用于蒸养制品。

8、关键性能:分散能力,是对光亮塑面、增强、耐磨,特别对色彩持久性起关键作用的性能。简单检测方法:将少量水泥面料与水拌成团状(水灰比为0.3,或更低),然后,加入面料量2%的光亮剂,充分搅拌均匀,这时,团状物应变成稀浆,放在玻璃板或塑料膜上,能完全流平,多次堆起,能再流平,关键是要能持续相当的时间,如30min以上。
9、产品稳定性可达八年:即使反复经历冷冻、结冰、溶解,也不影响产品稳定性及使用性能。
四、推荐掺量:液体掺量为胶凝总量的1.5~4.0%。
五、使用方法
1、直接掺入混凝土中。2、可使用本品配制其它混凝土外加剂,须经试验确定。

Concrete High-range Water-reducer SM

Concrete High-range Water-reducer SM (Sulfonated Melamine-formaldehyde Resin) is a polymer electrolyte, SM is the best one of existing concrete admixture in comprehensive properties.
It is able to prepare high-strength concrete and flowing concrete by adding SM into Ordinary Portland Cement. For high-strength concrete the compressive strength will reach or surpass 80MPa.This concrete is largely used in high-raise building and many important prestressed concrete structure of civil engineering. The flowing concrete is usually used for in-site casting and pump concreting,such as mass foundation and other structure with closs arranging reinforcement .
It has a excellent compatibility for Aluminous Cement. It metallurgical industry SM is often used as major admixture for refractory concrete, included castables and field mixes.
The product of SM is of a white or transparent colourless water solution. Owing to this it can be extensively used in inorganic decorative materials such as man-made marble,terrazzo,paints and various gypsum products .

Principle Technical properties
1.For dosage within 0.5~1.0% by weight of cement,the water reduction rate will be 20~25%2. When dosage is appropriate , It is able to increase the compressive strength of concrete and mortar by 40~100% at one day,by 30~60% at 28 days . The later age strength also in crease (about 20%) .
3. It is able to prepare high strength concrete (60~80MPa,even higher) by using 45.5#~55.5# Ordinary Portland Cement .
4.Adding SM to refractory concrete,from Aluminous Cement,the strength after drying at 110℃ and after burning at high temperature will increases obviously(by 60~170% for compressive).
5. Because of no air-entrainment SM can be used curing of concrete and their products.
6. The SM is usually applied for α-hemi hydrate gypsum and β-hemi hydrate gypsum,When dosage is 0.5~1.0% by weight of gypsum,It is able to increase the strength of gypsum by high water-reducing rate.
