Quantity: 2000Metric Tons Specs:Na2SO4 content 5% max Payment Method: TT or LC Naphthalene based superplasticizerSodium Naphthalene Formaldehyde was cited by the chemical synthesis of non-air-type superplasticizer. Chemical Name naphthalene sulfonate formaldehyde condensate, which for the dispersion of cement particles have a strong role. Pandemic on the state of preparation of concrete, there are early strength, high strength requirements of in-situ concrete and to the system components, there is a good use of effects, the overall advancement and improvement of various properties of concrete, widely used in roads, bridges, dams, port terminals, tunnels, electricity, irrigation, and industrial and civil engineering, steam-cured and the Nature Conservancy and other components to the system.Sodium content currently on the market to be divided into high concentration and low concentration of.The following is a low concentration of the indicators:1, the main technical indicators:1, Appearance: yellow brown powder powder, liquid brown viscous liquid.2, solid content: powder ≥ 94%, liquid ≥ 40%3, fluidity paste ≥ 230mm.4, sodium sulfate content of ≤ 10.5, chloride ion content ≤ 0.5%.2, performance characteristics:1, in the concrete strength and slump was basically the same time, can reduce the amount of 10-25% of cement.2, in the water-cement ratio constant, so that the initial slump of concrete to improve more than 10cm, reducing the water rates up to 15-25%.3 pairs of concrete early strength significantly enhance the effect, its strength is increased the range of 20-60%.4, to improve the workability of concrete, and comprehensively improve the physical and mechanical properties of concrete.5, for a variety of cement, adaptability, and other various types of good compatibility of concrete admixtures.6, especially for the use of concrete works in the following: fluid concrete, plastic concrete, steam curing concrete, impervious concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength and ultra-high-strength concrete .Third, dosage range:Powder 0.75-1.5%; liquid :1.5-2.5%.Fourth, pay attention to:1, using porous aggregate advisable to add water when mixing, coupled with water-reducing agent.2, when the slump is larger, should be noted that vibrator long time is not easy, in order to prevent bleeding of water and stratification.Naphthalene based superplasticizer Na2SO4 in accordance with its products, the level of content can be divided into high-concentration products (Na2SO4 content of "3%), the concentrated products (Na2SO4 content of 3% ~ 10%) and low-concentration products (Na2SO4 content of "10%). Most naphthalene superplasticizer synthetic plants possess the Na2SO4 concentration at 3% or less capacity, and some advanced enterprises may even be controlled at below 0.4%.Naphthalene superplasticizer is China's current production of the largest and most widely used high-performance water-reducing agent (accounting for more than 70% of superplasticizer dosage), which is characterized by higher water reduction (15% ~ 25%), not cited gas, the impact on the setting time is small, with cement adaptability is relatively good, with a variety of other additive compound used, the price is also relatively cheap. Naphthalene series water reducer is often used in the preparation of high fluidity, high strength, high-performance concrete. Pure naphthalene superplasticizer admixture of concrete slump loss faster. In addition, the naphthalene superplasticizer and some need to improve the adaptability of cement. |
