Notes for Use
• Select the corresponding type of modified starch according to the drilling temperature, salt content and mud system type, and avoid blind use.
• The addition amount is strictly controlled according to the engineering design requirements, and excessive addition is prohibited to avoid affecting the mud fluidity.
• It should be stored in a dry, cool and ventilated warehouse, away from water and moisture, and the storage period is 12 months under normal temperature.
• When mixing, it should be slowly added to the stirring water/mud, and fully stirred to ensure uniform dispersion and avoid agglomeration.
