Mica the sericite is widely applied in vocation of the welding rod , the rubber , plastics , dope fireproofing , antisepsis , porcelain and ceramics , heat preservation , cosmetics , paint , deckle , spin and weave , metallurgy etc 绢云母的特性被广泛地应用在电焊条橡胶塑料涂料防火防腐油漆陶瓷保温化妆品颜料造纸纺织冶金等等行业。
So it is required to increase the dispersion property and improve mechanic intensity and synthetic capability . in this paper , stearic acid , silane ( kh - 550 ) , silane ( kh - 570 ) are chosen to modify the surface of sericite 因此，对绢云母进行表面改性，可改善其表面的物化性质，增强其与有机高聚物的相容性，提高其分散性，以提高材料的力学强度及综合性能。
The ore - forming material is mostly from volcanic rock , and sub volcanic rock provides the main thermal and some mineral materials . the ore - forming fluid is from meteoric water . as a result , it should be a kind of adularia - sericite type of epithermal gold deposit 成矿物质主要来自矿区火山岩围岩，次火山岩提供了主要热源和部分矿源，成矿流体来自大气降水，矿床成因类型为低硫化物冰长石?绢云母型浅成低温热液型金矿。
The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid , meanwhile , the volcaniclastic rocks were modificated by the thermal fluid activity , for example , sericitization of plagioclase , chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud , the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks 同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的“催熟”加热作用，微量元素则出现异常现象。
Sericite is a new kind of non - metallic mineral filler . it is widely used in the field of high molecular materials and compound materials industry , such as plastics , rubbers and glutinous agents . but sericite is different from organic high polymers in interfacial property , and hard to disperse in them 绢云母是一种新兴的非金属矿物填料，在塑料、橡胶、胶粘剂等高分子材料工业及复合材料领域中应用广泛，但由于绢云母是亲水性非金属矿填料在材料与有机高聚物间的界面性质不同，相容性差，难以在高聚物中均匀分散。
The metallic mineral has very few content ( 1 % - 2 % ) , the mineral of ore is mainly of pyrite , chalcopyrite , limonite , aurum and electrum etc . the gangue mineral is composed of chalcedony , micro grained quartz , calsite , sericite , adularia , aragonite , chlorite , laumontite , pyrophyuite , kaolinite and so on , which show the typical mineral assemblage of epithermal 矿石为典型少硫化物型，金属矿物含量极少( 1 - 2 ) ，主要有黄铁矿、黄铜矿、褐铁矿和自然金、银金矿等。主要脉石矿物有玉髓、微粒石英以及方解石、绢云母、冰长石、文石、绿泥石、浊沸石、叶腊石、高岭石等，属典型低温矿物组合。
The absorption is ascribe to physical absorption . silane combines with h of hydroxyl on surface of sericite , the absorption is ascribe to chemical absorption . in silane and stearic acid cooperation modification , c = o absorption peak appears in spectrum and the regional vibration of si - o - si becomes wide , which shows the physical absorption of stearic acid and chemical absorption of silane produce an effect on surface of sericite 采用红外光谱对绢云母改性机理进行分析，结果表明，硬脂酸改性绢云母吸附强度较弱，容易脱附，以物理吸附为主；硅烷改性绢云母，与绢云母表面的羟基形成氢键，以化学吸附为主；硅烷与硬脂酸复合改性，其光谱中出现了c = o键特征吸收峰，并且si ? o 、 si ? o ? si振动吸收区变宽表明复合偶联剂在绢云母表面既有硬脂酸的物理吸附，又有硅烷的化学吸附。
Because of their excellent characteristics , superabsorbents are widely used in health , agriculture and horticulture applications . based on the influencing factors , such as type of structural layer , interlayer charge , interlayer distance , cation exchange capability , surface area and ratio of swelling , kaolinite , sercite and bentonite are choosed as the mineral fillers to synthesize the superabsorbent composite 本文从粘土的结构层型、层电荷、层间距、阳离子交换容量、比表面积和膨胀率等各方面综合比较研究粘土矿物的性质，选择了高岭土、膨润土和绢云母这三种粘土矿物作为无机填料，制备粘土?有机聚合物超吸水性复合材料。
