Properties
The polymer body contains strong cationic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the waste water through electro-neutralization and bridging adsorption. It is very effective in flocculating, decolouring, killing algae and removing organics. The product enjoys small dosage but can cause big flocs, rapid precipitation and low turbidity residue, and it can also produce small amount of sludge. It is adaptable to wide range of pH value, between 0.5 and 1.4. This product is smelless, tasteless and harmless. It can be widely used to treat source water and sewage water.
Application field

APPLICATION METHODS
When used alone, it should be diluted to the concentration of 0.5%-0.05% (based on solid content). When used to treat different source water or waste water, the dosage is based on the turbidity and the concentration of the water. The most economical dosage is based on the trial. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the construction chemicals and materials in the water and the flocs can not be broken. It is better to dose the product continuously.
PACKAGE AND STORAGE
1. It is harmless, no-flammable and non-explosive, it can be stored at room temperature, it can not be placed in the sun.
2. It is packaged in plastic drums with each containing 125kg and 1000kg.
The newest asphalt emulsifier for micro-surfacing construction SM-LS (80%) with 4 types according to the weather condition (Spring,Summer,Autumn,Winter) . Performance as below :
1. initial setting within 15 minutes;final setting within 55minutes
2. open to traffic within 1 hour
3. allowed to mixing for 6 minutes
4. 100% meet the standard of the aggregates cohesion test
5.Dosage (60% -70% asphalt concentration) : 1.2-1.5% (normal asphalt); 2-3% ( modified asphalt)
Emulsified asphalt is means the asphalt,emulsifier and water together under the certain process to become liquid asphalt which is in oil in water or water in oil condision .
Emulsified asphalt is normally used at high temperature of asphalt road, through mechanical mixing and chemical stability method - emulsification, diffusion into the water and liquefaction at room temperature to become a very good a road building material which with low viscosity and good liquidity function.It can be used under common temperature and also can be used togetehr with cold and wet stone material.
Our New asphalt emulsifiers including Rapid setting type, Slow setting type, Medium setting type,super slow setting type,Slow crack rapid solidification type and nonionic emulsifier for remixed formulation. Our products can solve your needs of emulsification and application requirements by different schemes, there are several optional basic type, can be used alone and also can be based on the need to meet with the complex use of emulsifiers with different cracking speed requirements of asphalt emulsion, let the asphalt particles uniformly dispersed in the water solution which mixing with emulsifer then to get the stable emulsion.Products used by domestic and foreign customers for long-term and get very good feedback, can be comparable with any global brand of emulsifier.
Below types of emulsifier is used for asphalt emulsion.clients can flexible collocation of various emulsifiers according to their needs, in order to meet the requirements of demulsification speed. For example: SM-LM mix with SM-LLL,can slow the demulsification speed; mix with SM-LF,can fast the demulsification speed. During the process of asphalt emulsion, can Increase emulsification if used together with SM3B/SM-LS.The dosage of Compound emulsifier will be around 0.3-0.5% of the asphalt emulsion, it is better to test by client for the exactly dosage according the different quality of asphalt and the solidification speed. This series of products can be used for routine emulsified asphalt preparation, preparation of cold mix type high content of emulsified asphalt (instead of hot asphalt), also can used in asphalt concrete production process , welcome the industry professionals to discuss cooperation.
Special declaration: all below types no need any acid during the emulsion process,and also will have Anti-corrosion effect for the equipment.
