海韻牌BT-7035型海泡石Chaton brand BT-7035 type sepiolite執(zhí)行標準： JC/T 574-2006Execution standard: JC/T 574-2006 用于鉆井泥漿、油脂脫色和一般工業(yè)用海泡石，其他用途的海泡石亦可參照采用。 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。以每百克樣品消耗 0.1mol/L **標準溶液的體積（ mL ）來表示?！ hat sepiolite activation degree. 100 grams per sample co
nsumption 0.1mol/L sodium hydroxide standard solution volume (mL) to represent. 游離酸Free acid 海泡石粘土中以游離狀態(tài)存在的酸，以 H2SO4 計，以 % 表示?！ epiolite clay in the free state existing acid, baosteel H2SO4 gauge to % said. 有害礦物Harmful mineral 主要指斜纖維蛇紋石、角閃石、透閃石等有害礦物。 Mainly refers to the serpentine, Angle oblique fiber flash stone, through flash stone such harmful minerals.1 、產品按用途分為鉆井泥漿用海泡石、油脂脫色用海泡石和一般工業(yè)用海泡石三類。1, products of the end-use divided into drilling mud with sepiolite, grease decoloring with sepiolite and general industrial use sepiolite three categories.2 、油脂脫色用海泡石根據脫色力分為 I 類、 II 類、 III 類。2，the grease, decoloring with sepiolite according to decoloring force into the I type, class II, III class.3 、一般工業(yè)用海泡石根據纖維長度分為一般工業(yè)用纖維狀海泡石和一般工業(yè)用粘土狀海泡石兩種，按其質量分為 I 類、 II 類、 III 類。纖維長度小于等于 0.25mm 為粘土狀海泡石，按**大細度分 0.250mm 、 0.150mm 和 0.075mm 三種規(guī)格，分別用 250 、 150 、 75 表示；纖維長度大于 0.250mm 為纖維狀海泡石，按纖維長度分為 4mm 、 3mm 和 2mm 三種規(guī)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 鉆井泥漿用海泡石技術要求Table 1 drilling mud with sepiolite technical requirements
