The blended powder of nylon 12 and wollastonite was molded by selective laser sintering ( sls ) 摘要将尼龙12与硅灰石的混合粉末进行选择性激光烧结成型。
The optimum content of stearic acid used to modify wollastonite is 2 % of wollastonite weight 硬脂酸改性硅灰石的最佳用量为硅灰石质量百分比含量的2 。
Geological characteristics and genesis study of the wollastonite deposit in the mengshan area , jiangxi province 江西蒙山地区硅灰石矿床地质特征及成因探讨
Contrasts of structure and properties of two nano - tio2 wollastonite composites with wollastonite having different partical sizes 硅灰石复合体结构及性能对比
Research on minimum dimension of nano - wollastonite structure and developments of the preparation of wollastonite powders 硅灰石最小纳米化结构探讨及其粉体制备的研究现状
Cenospheres are hollow silicate micro - spheres extracted from the fly ash generated in coal - fired power plants 漂珠是从火力发电厂的粉煤灰中提取的中空硅灰盐质空心微珠。
As to wollastonite , the modification effect using stearic acid is better than that using aluminate ester and silica alkane 硬脂酸改性剂对硅灰石的改性效果优于铝酸酯和硅烷。
4 ) the effects of fly ash and silica fume on plastic shrinkage cracking were related to the actual w / b ratio of concrete mixture 对粉煤灰，这一水胶比界限约为0 . 36 ，对硅灰约为0 . 4 。
Rpc200 having outstanding performance can be got when silica fume quantity is approximately 25 % ~ 35 % of cement quantity 当硅灰掺量约为水泥掺量的25 % ~ 35 %时，可获得性能较好的rpc200 。
High spicific surface , tiny granule diameter , goodactivity , can be used as substitute of well cement or silica flour to imporve well quality 比表面积大，粒径微小，具有良好的胶凝性能，可替代井油水泥和/或硅灰（漂珠） ，改善固井质量。
