For sewage with suspended particles, and coarse, high concentration, positively charged particles, and the neutral or alkaline water pH value, because the molecular chain of anionic flocculant contains a certain amount of solid particles suspended in water, so that the particles are bridged to forms large floccules. Therefore, it accelerates the sedimentation of particles in the suspension, which has a very obvious effect of speeding up the clarification of the solution, and promoting filtration. This product is widely used in the treatment of chemical industrial wastewater and liquid waste, municipal sewage treatment, and water treatment in tap water industry, purification of high turbidity water, clarification, coal washing, mineral processing, metallurgy, steel industry, processing industry of zinc and aluminum, electronics industry, etc.
(1) Used in textile, printing and dyeing industry.
The anionic flocculant is used as a sizing agent and finishing agent for fabric treatment, and can generate a soft, wrinkle-proof, and mildew-proof protective layer. With the characteristics of strong hygroscopicity, it can reduce the rate of breakage during spinning. Anionic flocculant as a post-treatment agent can prevent static electricity and flame retardancy of the fabric. When used as the printing and dyeing auxiliary, anionic flocculant can enable the product to have high adhesion fastness and brightness, and can also be used as a non-silicon polymer stabilizer for bleaching.
(2) Used in the petroleum industry
It has been widely applied in oil recovery, drilling mud, waste mud treatment, preventing water channeling, reducing friction, improving oil recovery, and tertiary oil recovery.
(3) Used in the paper industry
First, it can help increase the retention rate of fillers and pigments so as to reduce the loss of raw materials and environmental pollution; secondly it can increase the strength of the paper (including dry strength and wet strength). In addition, anionic flocculants can also increase the tear resistance and porosity of the paper to improve the visual and printing performance. Besides, it is adopted in paper of food and tea packaging.
(4) Used in the food industry and others
Anionic flocculant is used for cane juice clarification and syrup phosphorus floating extraction in the production of cane sugar and beet sugar, and is used in the enzyme preparation fermentation broth flocculation and clarification industry, and also used for the recovery of feed protein with a stable quality and good performance, and the recovered protein powder has no adverse effects on the survival rate, weight gain, and egg production of chickens. What's more, anionic flocculant is adopted in synthetic resin coatings and water plugging in grouting materials of civil construction, building materials industry, cement quality improvement, construction industry adhesives, joint filling repair and water blocking agents, soil improvement, electroplating industry, printing and dyeing industry, etc.
