polyacrylamide

Product Description

The model C***0 belong to New-type water-treatment chemical*-water midium dispersing type ***** is mainly used as flocculants and dewatering reagents for industry waste water and sewage; retention aids and intensifier in paper making industry; waste water treatment in pharmaceutical, leather making, printing and dyeing industry waste water treatment, and organizer in textile industry. According to the properties of product, the followings should be noticed during the process of preparation and usage. 1, The concentration should be too high, normally between 0.*5%*0.5%. 2. During the process of dissolving the product, stir slowly while adding the product slowly to half-water-filled tank, this can help the product disperse rapidly. Addition of product without stirring the mixture, or addition of water after product into the tank is forbidden to avoid the formation of big chunk, which is difficult to dissolve. 3. Water used to prepare solution should be neutral. Normally, tap water is fine in this process, no specific requirement. 4. The speed of stirring or agitation should be in a proper range. Relatively slow speed can cause increase of dissolution time and low level of dispersion; in contrast, too furious speed can break the linear chain, consequently, damaging the relevant properties of the product. 5. Normally, the product can be dissolved in water at room temperature, with no heating needed. In cold weather like winter, the solution temperature can be raised up to ****0℃ to increase dissolution speed, but should not exceed *0℃ to avoid degradation of the product. 6. Low concentration of product solution should be prepared freshly for use and the storage time can not exceed *4h, otherwise, the quality of the product could degrade. 7. Formation of two layers for the emulsion after long time of storage does not affect the quality of the product and the emulsion can still be used after stirring to form homogenous phase.
