YuXinHuan is specialized in the production of polyacrylamide water treatment products manufacturers, the classification and use of the product should be individual understanding of the matter, the shape of polyacrylamide is mainly for the granular, powdered, powdered for the less common, for the following detailed introduction to the use of this shape of the standard matters.
Powder polyacrylamide use matters:
1. PAM dissolution: powdered PAM added to the water, it will immediately produce puffing, if a time to add too much agglomeration will occur, the formation of the so-called “dragon’s eye, fish-eye”, not only is difficult to dissolve, and often cause dosing pump clogging accidents; Secondly, too small PAM powder, put into the dissolving tank because of light, it is easy to In the air scattered, resulting in pollution of the operating environment. The correct dissolution method is usually a small amount of stirring to the water constantly add quantitatively, the use of one side of the sprinkle side of the dissolution method, which can effectively avoid the “fish-eye” insoluble material, but also effectively shorten the dissolution time.
2. dissolving and stirring conditions: dissolving tank to the cylinder type is good, and the height of the liquid level in the cylinder for the cylinder diameter of 1.2-1.5 times or so for the ideal level. Square cylinder corners due to turbulence effect, easy to produce dead ends, in order to avoid the accumulation of undissolved particles stagnant material dead ends, should be avoided as far as possible. The mixer can be vertical or horizontal.
3. PAM dissolved concentration: Powder PAM is generally used in the content of 0.05-10% of the aqueous solution, the specific concentration must be determined according to the specific characteristics of the sludge.
4. Precautions: As mentioned before, PAM is almost non-toxic, and some hydrolysis products may be irritating. During the operation, the inhalation of PAM powder and the adhesion of dissolving solution to eyes, nose and skin should be avoided as far as possible, once it happens, it should be rinsed immediately and repeatedly with a large amount of running water. When dissolving operation, it is better to wear protective equipment such as goggles and rubber gloves. Around the site, the place splashed by the dissolving liquid will be more dangerous due to sticky and slippery, try to rinse it with water and keep it in dry condition.
Anionic, cationic polyacrylamide is more commonly used two classified products, according to the application of different industries in different aspects, can be selected for use of this product. Daily life wastewater, industrial wastewater, paper wastewater and other industries water treatment, choose polyacrylamide as the advantageous products.
