Ferrochrome lignosulfonate (FCLS)

Description

FCLS is a specially prepared thinner and fluid loss control agent used in drilling fluids. It has the characteristics of anti-high temperature and anti-electralytes etc. The product`s all technical index have been already reached SY/T******5 quility standard. Physical and chemical index Item Requirement Appearance Blackish brown powder Material insolution to water % ≤ 2.5 Moisture % ≤ 8.5 Calcium sulfate % ≤ 3.0 Total Fe % 2.5~3.8 Total Cr % 3.0~3.8 Cr complex % ≥ *5 Characteristics 1、With excellent thinning performance and filtration control capacity and powerful anti-electrolytes capacity , it is suitable to all kinds of muds. 2、Be effective at temperature more than **0~**0 ℃ , it can also be used at the temperature above **0℃ when cooperated with lignite derivatives and other temperature-resisting chemicals. 3、FCLS is a good emulsifier for oil in water mud. Application FCLS may be added into drilling fluids either in the form of solution or powder , keep PH between 9.5 ~ *0.5.As a thinner :0.5 ~ 1.0%.As a fluid loss control agent:2.0 ~ 5.0%. Package *5kg net weight. With PE film bag inside and paper-plastic complex bag outside.
