In recent years , the study on enhancement of intensity and toughness of high polymer filled with wollastonite is a heat - researched problem in material science 近几年来，硅灰石对高分子材料的增强增韧研究已成为材料科学研究的热点课题。
Abstract : a separability study is conducted of pingle mine s grammite ore , which is associated with weakly - magnetic gangue minerals , such as mussite and garnet 文摘:对伴生有透辉石、石榴子石等弱磁性脉石矿物的广西平乐硅灰石矿进行了可选性研究。
The analysis indicates that micropacking silica fume works to the density and relative density of rpc , and its pozzolanic effect helps the strength of rpc 硅灰的微填充效应有利于提高活性粉末混凝土的密度和相对密度，而火山灰效应有利于提高其强度。
In order to reduce the cost and increase the rpc strength , the substitution of mixed minerals such as ultra - pulverized fly ash for silica fume quantity can be lower than 20 % 为降低成本而又不大幅度损害活性粉末混凝土的强度，超细粉煤灰等矿物掺合料替代硅灰的量不宜超过加20 % 。
Advantages of resources with regards to the mineral resources , the wollastonite reserve , with a deposit of 6 million tons , ranks the first in the south china adn second in the country 矿产资源，硅灰石以600万吨储量列南方之冠、全国第二；铁矿储量占全省已探明的87 % ，煤储量占10 % ；钨储量2
Moreover , the addition of wollastonite rose the thermal distortion temperature of the sls part , improved the dimensional accuracy of the sls part , and lowered the material cost greatly 同样，加入硅灰石后，可使烧结件的热变形温度大幅度提高，同时提高了烧结件的尺寸精度，大大降低了材料成本。
By being compared the adsorbent rate to tio2 , the minerals ( diatomite , sepiolite , vermiculite , grammite , kaoline , bentonite ) has selected elementarily in the paper 本文通过硅藻土、海泡石、蛭石、硅灰石、高岭石、膨润土等六种矿物对tio _ 2的吸附效果及吸附量的比较，对天然矿物进行了初步筛选。
By means of scanning electronic microscope , i have done some observation and researches on the scattering property of wollastonite in polypropylene and the cohesive property between wollastonite and polypropylene 应用扫描电子显微镜对改性硅灰石在聚丙烯中的分散性及其与聚丙烯的界面结合性进行了观察和研究。
( 2 ) considering the effect of wollastonite particle size on performances of composite material , we can find out that , with particle size smaller and smaller , the performances rise at first and then fall ( 2 )硅灰石粒径对复合材料性能的影响实验表明，随着硅灰石粒径的减小，其机械性能呈现先上伸后下降的趋势。
Based on this system the cracking resistence of portland cement paste system was tested . also the effect of fly ash , slag , silica fume and admixtures on the cracking at early ages was studied 本文对纯硅酸盐水泥胶凝体系的抗裂性能进行了研究，同时试验考察了粉煤灰、矿渣、硅灰和外加剂对胶凝体系早期抗裂性能的影响。
