Natural bentonite

 
Natural bentonite is produced by Camp Shinning. Activated bentonite clay is suitable for all type of freshwater mud rotary drilling.Bentonite CP-DRI is used in vertical drilling fluids to increase viscosity and filtration control. CP-DRI is also ideal in drilling fluids because it expands when exposed to water. This expansion helps down hole formations to be sealed from invading drilling fluids. The Drilling bentonite extracts the drill cuttings from around the drill bit, which are then floated to the surface. Bentonite also serves to cool and lubricate the drill bit as well as seals the drill hole against seepage and to prevent wall cave-ins. It is mainly use in fresh pure water rotary drilling conditions as water quality will affect bentonite performance.

How To Use Thixotropic clay

1. Pre-gel method
2. Polar activator is not necessary:
3. Main solvent xylene: 95~92%
4. Thixotropic clay :5~8%
5. Dispersing 5-15min, gel is finished.
6. Polar activator is necessary:
7. In aromatic solvent, the recommend activator is methyl acohol/water (95%/5%)/ acolhol/water (95%/5%), the dosage is 33%-45% based on the weight of CP-720B.
8. In mineral oil (such as 200#), white oil, diesel oil, the recommend activator is methyl acohol/water (95%/5%)/acolhol/water(95%/5%), the dosage is 33%-60% based on the weight of CP-720B.
9. Procedure of adding gel:
10. Charge solvent and resin to mill
11. Slowly add the gel
12. Dispersing 5-10min
13. Wetting agent (if required)
14. Disperse completely to desired fineness
15. Dilute to desired viscosity
16. Add directly with powder
17. Charge solvent and resin
18. Add Thixotropic clay slowly
19. Disperse 10-15min

D .Add polar activator (if necessary)

1. Disperse 10-15min at high speed
2. Add wetting agent and other additive
3. G.Grind and next procedure

It can be added directly in powder under high shear condition. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.1%~2.0%. If add polar activator and make pre-gel, better efficiency can be achieved.
