Product Description

Flocculants

(1) Separate red mud from alumina.

In the alumina production process, red mud s separation and washing uses a sedimentation tank through the Bayer Process. In order to speed up the red mud settlement, the traditional method is to add flour, wheat bran and other natural polymer flocculants. With the continuous improvement of alumina production, the sedimentation tank often runs muddy. Using PAAS instead of the natural polymer can greatly improve the velocity of red mud settlement in Bayer Process, and the effect to pure the product is better. In a word, the flocculants of PAAS can enhance the productivity and quality of the sedimentation tank.

(2)Clarify the liquid ammonia in Combined-soda Process

During the Combined-soda Process, solid salt is often added in order to get solid ammonium chloride, through which calcium and magnesium ions and sediment will be mixed. To ensure the quality, liquid ammonia shall be purified before carbonization. Adding a little PAAS in Doyle-type bucket will speed the clarification and gain high purity.

(3) Refining salt in brine

In chloral-alkali and other chemical industries, PAAS is the first choice of flocculants for refining salt.

(4) Clarify the sugar juice

There is some particle which is absorbed by lime suspending in the sugar juice. Adding a little amount of PAAS, can speed up its settlement, and promote the clarification of the juice.

(5)To clarify natural water

There is one carboxyl in each chain of the high molecular weight PAAS, which belongs to ion flocculants. Even the muddy water as the Yellow River, can be quickly clarified by adding 10 ppm of this flocculants.

(6) To remove phosphate from the sewage

Mixing sufficient Mw> 2 x 106 PAAS into sewage that contains phosphate, can precipitate down the solid particles (including phosphate) suspending in the sewage.

(7)To prevent water leakage in the sewage pool

In order to prevent the sewage pools or sewage in the depression leakage, usually we mix bentonite with the soil which form the sewage pool together to make the pool wall. But when the water contains soluble industrial waste, bentonite seepage would not be suitable. At this time we should utilize mixture soil. Its elements are: 99% (wt) of sodium-type bentonite, 0.5% (wt) PAAS and 0.5% (wt) of the acid TSP. The results show that the efficient of a mixture of soil is higher 10 times than the untreated bentonite

(8) Soil conditioner

PAAS can form soil into stable aggregates, thus improving the soil tillage and plant growth, reducing the loss of water from the soil, avoiding the upper soil being washed away in the heavy rain.

(9) To isolate foreign oil from the latex

In machining emulsion lubrication and cooling of metal are used. In the use of this emulsion, some irrelevant foreign oil is often mixed with, its viscosity is generally higher than that of the raw material. If retained in the process, it can cause the deterioration of emulsion s lubricating and must be removed from the emulsion. The method is to add PAAS into emulsion and stirring, and then heat it at high temperatures, making foreign oil come together and be isolated.
