Non - ionic polyacrylamide is a water - soluble polymer or polyelectrolyte . Because of its molecular chain contains a certain number of polar groups , it can adsorb suspended solid particles in water , make the interparticle bridging or pass charge neutralization and make the particles agglomerate.Therefore , it can accelerate the settling of the particles in the suspension , accelerate the clarification of the solution , promote the filtration and the like , and is mainly used as a flocculating agent : because the molecular chain contains a certain amount of polar gene ,Solid particles that make large flocs between particles . It accelerates the sedimentation of the particles in the suspension , and has obvious effect of accelerating the clarification of the solution and facilitating filtration .
Characteristics of non - ionic polyacrylamide products :
1 , good water solubility and complete dissolution in cold water .
2 . Add a small amount of non - ionic polyacrylamide so as to be subject to great flocculation effect . Generally only 0.01 -10 ppm ( 0.01 -10 g / m3 ) is added to give full play to the effect .
3 . At the same time , nonionic polyacrylamide and inorganic flocculating agent ( polymeric ferric sulfate , polyaluminium chloride , iron salt , etc . ) can be used to show a greater effect .
Use of non - ionic polyacrylamide :
1 . It is widely used in the treatment of chemical industrial waste water and waste liquid , municipal sewage treatment , especially when the sewage is acidic , it is most suitable to use this product . It can be used in combination with inorganic salt such as inorganic flocculating agent , polyiron , polyaluminium and the like .
2 . Used in petroleum industry , oil production , drilling mud , waste mud treatment , prevention of water channeling , reduction of friction resistance , improvement of recovery and tertiary oil recovery .
3 , the sizing agent is used for spinning sizing agent , the slurry is stable in performance , few in pulp falling , and the fabric cutting rate is low , and the cloth surface is smooth .
4 , for paper industry , one is to improve the retention rate of fillers , pigments and the like , so as to reduce the loss of raw materials and the pollution to the environment ;secondly , the strength of the paper ( including dry strength and wet strength ) is improved ,improve vision and printing performance and also for use in food and tea packaging paper .
5 . Other industries , food industry , used in cane sugar , sugar beet sugar production cane juice clarification and syrup phosphorus floating method extraction . Enzyme preparation fermentation liquor flocculation clarification industry , also used for feed protein recovery , quality stability , good performance , recovered protein powder to chicken,the survival rate of the synthetic resin coating , the civil grouting material , the building material industry , the cement quality , the building industry adhesive , the joint repair and water plugging agent , the soil improvement , the electroplating industry , the printing and dyeing industry , and the like are improved .The non - ionic polyacrylamide is a polymer or polyelectrolyte , and the molecular chain contains a certain amount of polar gene capable of absorbing suspended solid particles in water , so that the interparticle bridging bridge forms a large floc .
The nonionic polyacrylamide nonionic polyacrylamide is a water - soluble polymer or polyelectrolyte .
The suspended solid particles in the water can accelerate the sedimentation of particles in the suspension , accelerate the settling of the particles in the suspension , accelerate the clarification of the solution , promote filtration and the like , and are mainly used for accelerating the sedimentation of the particles in the suspension .
flocculation settling and settling clarification treatment of various industrial waste water , such as waste water treatment of papermaking and pulp waste water , waste water treatment in the beneficiation and metal smelting processes , waste water treatment of steel plants and stone processing plants , and the like .polyacrylamide is the key and basis for the water treatment technology of flocculation . The efficient and low - consumption , safe and harmless organic flocculant has been one of the hot spots in the field of flocculation science and a flocculating agent .
