The main uses of polyacrylamide (2)

4. Textile printing dyeing industry

In the Textile manufacturing, PAM, as a sizing agent finishing agent for fabric post-treatment, can produce a soft, wrinkle proof mold resistant protective layer. By utilizing its strong hygroscopicity, it can reduce the breakage rate during spinning; PAM as a post-treatment agent can prevent static electricity flame retardancy of fabrics; When used as a printing dyeing assistant, it can enhance the product's adhesion fastness brightness, can also be used as a non silicone polymer stabilizer for bleaching; In addition, it can also be used for the purification of textile printing dyeing wastewater.

5 Nerve gas Antidote

Petroleum additives generally use hydroxylamine (NH2OH, hydroxylamine) to remove the phosphine containing compound attached to acetylcholine ester, allowing it to be reactivated for acetylcholine hydrolysis reaction, in order to relieve the toxicity of sarin (a neurotoxic agent belonging to organophosphorus organophosphate compounds, organophosphates). However, the concentration of hydroxylamine is high, this high concentration of hydroxylamine can also cause toxicity. Therefore, the alternative method is to treat with PAM. A PAM of 10-6M is equivalent to the detoxification of IM hydroxylamine. In addition to PAM, there should be other compounds that can be used as nerve Antidote, such as obidoxime HI-6. These three Antidote all contain R2NOH nucleophilic group, each Antidote has slightly different antidote effects on different nerve agents.

6 Other fields

In the field of mining coal washing, using PAM as a flocculant can promote the sedimentation of solid substances in the water for mining coal washing recovery, clarify the water, recover useful solid particles to avoid environmental pollution; In the sugar industry, it can accelerate the settling of fine particles in sugarcane juice, promote filtration, improve the clarity of the filtrate; In the aquaculture industry, it can improve water quality, increase water transparency, thus improve water photosynthesis; In the pharmaceutical industry, it can be used as a flocculant for separating antibiotics, as a form forming adhesive for tablets, as a clarifier for process water; In the building materials industry, it can be used as a thickener dispersant for coatings, a coolant for sawn stone boards, a ceramic adhesive; In agriculture, it can be used as a high water absorbent material as a soil humectant seed culture agent. In the construction industry, it can enhance the hardness of gypsum cement accelerate the dehydration rate of asbestos cement. In addition, it can also be used as a protective coating for natural synthetic leather, as well as a granulating agent for inorganic fertilizers.

Physical chemical indicators:

This product, commonly known as a flocculant coagulant, is a linear polymer with a molecular weight between 3 25 million. The solid product has a white powder appearance, while the liquid product has a colorless viscous colloid shape, which is easily soluble in water almost insoluble in organic solvents. It is recommended to dissolve at room temperature during application, it is easy to decompose when the temperature exceeds 150 ℃. It is non hazardous, non-toxic, non corrosive. Solid PAM has hygroscopicity, flocculation, adhesion, drag reduction, thickening, good stability.
