Ⅰ. Characteristics：
1. With excellent thinning performance and filtrate reduction property .
2. Anti-high temperature can reach 200℃, it can cooperate with other admixture agent.
Ⅱ. Application:
1. MH-ⅠChrome-free thinner can be added into drilling fluids either in the form of solution or powder. After that, the PH of drilling fluids will decrease a little, so sodium hydroxide should be added to keep PH between 10.0~10.5.
2. As a thinner ,the recommended dosage is 1.0%(W/V) in fresh water mud , 1.5%(W/V) in salt water mud .
3. 25kg/bag with paper-plastic compound bag and valve bag.
