Polyacrylamide plays an irreplaceable role in Water Treatment Chemicals, Oilfield Chemicals, petrochemical, paper making, printing and dyeing industries, and often encounter some problems in use, the most common of which is the problem of polyacrylamide caking, customers encounter such problems will ask, caking polyacrylamide can also be used?
To answer this question, let's first talk about the reasons for the caking of polyacrylamide: polyacrylamide has a strong moisture absorption, it is easy to absorb water in the air, so that the particles expand, stick to each other and chain together to form a block.
1) During the production process, the drying is not dry enough, and it is immediately bagged, the moisture is covered in the bag, and the polyacrylamide absorbs the water, and the particles are bonded in one piece. (Generally, the inner bag is kept intact and not damaged)
2) In the rainy season or when the goods are placed in a humid place and the inner bag is damaged, the polyacrylamide absorbs the moisture in the air, so that the particles expand and bond together to form a block.
3) When the goods are placed, the height is too high, the goods squeeze each other, and the time is long, and there is the possibility of caking.
4) The most common is the beginning of the use of the product, the packaging is generally not intact, and after use, the inner bag is not tightly tied in time, the humidity of the use of the site is large, or a long period of time after use, etc., when the polyacrylamide has been found to be caked, which is also because the polyacrylamide has a strong moisture absorption.
Polyacrylamide is generally dissolved into a solution, so that the molecular chain of polyacrylamide can be fully extended, which can improve its utilization rate. The caked polyacrylamide will be very soluble, or only a small part of it is dissolved, even if the dissolution conditions can not be completely dissolved, and the insoluble polyacrylamide can not play its due role, resulting in waste. Although the caked polyacrylamide can be used, it will cause waste of materials, low utilization rate, and the block polyacrylamide that cannot be dissolved into the pipeline will cause blockage and affect production, and the dredging of the blocked pipeline is also extremely difficult. Therefore, it is recommended that you must buy qualified polyacrylamide and keep it properly.
