Polymer flocculant water treatment chemical anion polyacrylamideService
High quality raw material
Already have a stable customer base and sales steamProduct process
In acrylamide aqueous solution as raw material, under the effect of initiator, polymerization, polyacrylamide gel block generated in the reaction is completed by cutting, granulation, drying, crushing, finally prepared polyacrylamide products. According to the characteristics of the ion can be divided into nonionic, anionic, cationic and amphoteric four types.Usage
In other areas
Coal mining subsidence area, using PAM as flocculant mining, coal washing water can promote the recovery of solids, make the water clear, at the same time, the solid particles useful recycling, avoids the pollution to the environment; In the sugar industry, PAM can accelerate the sinking particles in juice, promoting filtration and improve leachate clarity; In the breeding industry, PAM can improve water quality, increase the light transmittance of water, improve water photosynthesis; In the pharmaceutical industry, PAM can be used as flocculant,
separation of antibiotics used as a tablet excipient adhesive and process water clarifying agent; In the building materials industry, PAM can be used as coating thickening dispersant sawing stone plate, coolant and ceramic bonding agent; In agriculture, PAM as high water-absorbing materials can be used as a soil moisture and seed culture agent. In the construction industry, PAM can enhance the hardness of gypsum cement, asbestos cement to accelerate the dehydration rate. In addition, PAM is also used as a natural or synthetic leather protective coatings and additives such as inorganic fertilizer granulation.
The number of coal washing pool dosing anionic polyacrylamide is a very important task. If the amount is too large, resulting in a waste, if the amount is not enough, it is difficult to have an effect, so the correct amount of reasonable should be 1/1000 to 2/1000 of the proportion, namely 1, 2 kg of amide, can use 1000 pounds of water. According to this index, under normal circumstances, can be in a certain period of time, the success of the separation of coal and water, after the separation will surface water out, and then leave the pool at the bottom of the slime, after drying and drying, can be when the normal coal use.
