Polymer chemical slurry is a synthetic polyelectrolyte based on a variety of monomers or copolymers. It is an organic polymer material. Ordinary chemical mud products are divided into solid and liquid. Solid form can be divided into particle form and powder form, while the liquid form is mainly reverse phase emulsion material. According to the dissolution degree, it can be divided into common type and fast dissolution type.

1. main performance:

Iron slurry army chemical mud slurry form not only has a good wall collapse effect, and can adsorption drill chips, the thickness of sediment generally not more than 10cm, according to the actual situation, not secondary clear hole, and the mud without cuttings, hole wall friction layer thickening, can effectively improve the friction bearing capacity of pile, through the site verification, using iron slurry army mud powder hole pile inspection class I pile reached 98%, and non-toxic, tasteless, no harm to the environment.

2. Procedures and precautions for use:

1, can be directly washed into the hole in the sprayed water, quickly dissolved, forming a better viscosity of the slurry, especially suitable for municipal sites with construction limitations.

2. Add the sprayed water into the mud pool, pump and pump it with the mud circulation pump for circulation, and then inject it into the hole.

3. According to the local water quality and the actual use situation, use caustic soda (or soda soda) aqueous solution to adjust the PH value, and it is recommended that the PH value is between 8-10.

4.  After the hole into the 1-2 drilling to stand for about 20 minutes before the hole.

5. The slurry level should not be 1m below the ground, let alone the half-hole slurry. Due to the reduction of the hole pressure, the wall protection capacity is reduced; and when pouring concrete, the formation without the slurry immersion is very likely to collapse.

1. Chemical mud used in rotary drilling rig can improve the bit life, reduce drilling times, shorten the drilling cycle, reduce drilling cost and improve drilling efficiency. It also has the advantages of easy preparation, low cost and low dosage.

2. Chemical mud used in rotary drilling rig is used for static mud wall protection drilling technology, mainly used to protect the stability of pile hole wall, soil, sand and other impurities produced in the process of flocculation drilling. Chemical mud for rotary drilling rig is a high molecular weight synthetic polymer. The chemical mud used in the rotary drilling rig can create a good viscosity environment at low concentration conditions. The rotary drilling rig uses the super long molecular chain of chemical mud to be wrapped in the disorderly dispersed mud, and the connecting bridge is formed through different layers to ensure the stability of the surrounding strata, and help the mud stick to the drilling chips after cutting, improving the drilling efficiency.

3. The chemical mud used in rotary drilling machine has a small proportion, very low sand content, high viscosity, strong permeability, strong durability, clean and environmental protection. Can effectively control the thickness of sediment, improve the bearing capacity of pile foundation, reduce the difficulty of pouring and construction cost, reduce workers labor intensity, greatly improve the labor intensity of workers since iron slurry army rotary drill with chemical mud products listed, has been applied in many large projects, the effect is remarkable, is the favour of many rotary digging construction units.

Drilling and flushing in drilling engineering is an important technology in drilling construction. In the drilling process, according to the actual drilling formation situation, the appropriate mud type is scientifically selected for flushing and drilling. In order to achieve the clear hole bottom rock powder, cool the drill bit, lubricate the drilling tool, protect the hole wall, and improve the drilling efficiency.
