Application of polyacrylamide as thickener in detergent

Polyacrylamide is very effective in treating waste water from washing fruits and vegetables or food packaging, but it must have strict quality standards and must be approved and guaranteed by specialized agencies.

Generally speaking, when using polyacrylamide, pour the powdered cationic polyacrylamide into the stirred cold water slowly in small batches, but the stirring speed should not be too fast to avoid molecular rupture of the flocculant polymer due to excessive shearing . Stirring is only to ensure that the solids of the cationic flocculant polyacrylamide are dispersed immediately and will not stick and agglomerate. The addition rate of the flocculant polymer should also decrease as the viscosity of the solution increases. When dissolving the flocculant, a slight increase in temperature can slightly increase the dissolution rate, but the water temperature should not exceed 60. The solution concentration of the high-molecular-weight cationic flocculant PAM* is 0.5%, while the solution concentration of the low-molecular-weight cationic flocculant PAM can be prepared to be 1% or slightly higher.

Polyacrylamide has the function of clean sewage treatment and has become an indispensable part of modern environmental protection industry, solving the problem of water shortage in our country.

What kind of force can be exerted by adding PAM polyacrylamide to the detergent?

Polyacrylamide can be used as thickener, settling agent, flocculant, water retention agent, sludge compressing agent and clarifying agent. It has a wide range of uses, low dosage and good effect. Now let’s take a look at the principle of the formula used in detergent. The main component of detergent is surfactant, which contains both lipophilic atomic group and hydrophilic atomic group in its molecule. During washing, due to stirring and agitation, the lipophilic atomic group of the active agent is combined with the oil droplet, and the hydrophilic atomic group is combined with the water, so that the originally insoluble oil and water are combined, making the washing much more convenient.

It is well known that the effect of adding PAM polyacrylamide in detergent is to increase consistency. Used as a thickener, it also has a strong traction effect and a certain chelating effect. It is generally recommended that the addition amount be between 1/1000 ~ 5/1000. The specific dosage depends on the actual usage and formula. However, it should be noted that the side effects of adding PAM are also great, and the drawing effect that is too strong is very unnatural. The detergent containing PAM feels slippery and it is not easy to rinse off. The solution becomes very turbid when thickened with inorganic salt. The detergent is easily decomposed and deteriorated. Due to its high degree of degradation, the detergent stinks.
