海韵牌BT-7035型海泡石Chaton brand BT-7035 type sepiolite执行标准： JC/T 574-2006Execution standard: JC/T 574-2006 用于钻井泥浆、油脂脱色和一般工业用海泡石，其他用途的海泡石亦可参照采用。 Used for drilling mud, grease decoloring and general industrial use sepiolite and other purposes of sepiolite can also refer to adopt. 活性度Activated degree 表明海泡石的活化程度。以每百克样品消耗 0.1mol/L **标准溶液的体积（ mL ）来表示。 That sepiolite activation degree. 100 grams per sample co
nsumption 0.1mol/L sodium hydroxide standard solution volume (mL) to represent. 游离酸Free acid 海泡石粘土中以游离状态存在的酸，以 H2SO4 计，以 % 表示。 Sepiolite clay in the free state existing acid, baosteel H2SO4 gauge to % said. 有害矿物Harmful mineral 主要指斜纤维蛇纹石、角闪石、透闪石等有害矿物。 Mainly refers to the serpentine, Angle oblique fiber flash stone, through flash stone such harmful minerals.1 、产品按用途分为钻井泥浆用海泡石、油脂脱色用海泡石和一般工业用海泡石三类。1, products of the end-use divided into drilling mud with sepiolite, grease decoloring with sepiolite and general industrial use sepiolite three categories.2 、油脂脱色用海泡石根据脱色力分为 I 类、 II 类、 III 类。2，the grease, decoloring with sepiolite according to decoloring force into the I type, class II, III class.3 、一般工业用海泡石根据纤维长度分为一般工业用纤维状海泡石和一般工业用粘土状海泡石两种，按其质量分为 I 类、 II 类、 III 类。纤维长度小于等于 0.25mm 为粘土状海泡石，按**大细度分 0.250mm 、 0.150mm 和 0.075mm 三种规格，分别用 250 、 150 、 75 表示；纤维长度大于 0.250mm 为纤维状海泡石，按纤维长度分为 4mm 、 3mm 和 2mm 三种规格。3, general industrial use sepiolite according to the fiber length is divided into general industrial with fibrous sepiolite and general industrial use clay shape sepiolite two kinds, according to its quality is divided into I type, class II, III class. Fiber length equal or lesser than 0.25 mm for clay shape sepiolite, at maximum fineness points 0.250 mm, 0.150 0.075 mm mm and three kinds of specifications, respectively for 250, 150, 75 said, Fiber length is more than 0.250 mm for fibrous sepiolite, press the fiber length divided into 4mm, 2mm 3mm and three specification.表 1 钻井泥浆用海泡石技术要求Table 1 drilling mud with sepiolite technical requirements
