Hari SP 20 of anionic polyacrylamide can be replaced by Chinafloc A2525
Anionic polyacrylamide is a linear polymer, it is widely used in sewage treatment, incense, glue, building materials and other industries. In addition to these uses, anionic polyacrylamide can also be used in the construction site piling process, mainly plays flocculation, lubrication, drag reduction, drill protection, plugging and other roles. The following is detailed introduction: construction site in the process of piling anionic polyacrylamide.
1, anionic polyacrylamide is a flocculant, its flocculation is very strong. The mud and cuttings produced in the drilling process can be formed into flocs under the action of anionic polyacrylamide, which is easy to clean up.
2. After the anionic polyacrylamide is dissolved, its solution has great viscosity and fluidity, which can lubricate the drill bit and drill pipe in the drilling process, reduce friction, reduce resistance, improve drilling speed and reduce drilling costs;
3. Anionic polyacrylamide can protect the sol particles in drilling fluid through multi-point adsorption, adhesive protection and void blocking, prevent the filtrate from entering the formation to cause clay water swelling and prevent shaft wall collapse;
4, anionic polyacrylamide can also play a role in plugging. A gel formed by anionic polyacrylamide can plug these fractures and loose formations when drilling fluid loses ground due to geologic conditions.
chinafloc A2525 saves time and money while improving construction quality and
reducing defects.
►Controls fluid loss in sands and gravels. Stabilizes excavations
►Highly concentrated. Very small quantities required
►Improves productivity of machines and crews
►Reduces chipping and cleaning of poured concrete
►Reduces or eliminates disposal costs. Product is environmentally safe
►Reduces transport costs and storage space requirements
►Requires less mixing/processing equipment, reducing capital investment, jobsite congestion, and fuel costs
This specification provides direction in the proper use of chinafloc A2525 and its additives while improving standardization, quality, and performance in the practice of slurry-displaced deep foundation construction. This document ensures
that engineers and engineering geologists can confidently predict the load carrying capacity of the piling being
constructed using an approved slurry, and to ensure that an approved slurry is not detrimental to the structural
capacity or service life of the piling.
