Pbo - b _ 2o _ 3 - sio _ 2 glass reacts with bismuth ruthenate and lead ruthenate is produced as transition layer . the transition layer can make the interface gradually change and the properties of resistors are improved at the same time . based on the study above , the way to get series of pastes was developed 铅硼硅玻璃粉体平均粒径对厚膜电阻的性能影响有一极值点,约为1 . 51 m ,在该点处膜层的方阻值最小,电阻温度系数绝对值最小,重烧变化率最接近零值。
The average partical size of bismuth ruthenate and pbo - b _ 2o _ 3 - sio _ 2 glass was researched . the smaller bismuth ruthenate partical is , sheet resistivity is lower and temperature coefficient of resistance ( tcr ) is more positive and the refiring change ratio is nearer to zero . the limit size of bismuth ruthenate partical is 0 . 56 m 研究了各相粉体平均粒径对膜层性能的影响,结果表明:钌酸铋平均粒径越小,膜层的方阻值越小,电阻温度系数偏正,重烧变化率越接近零值,球磨工艺的极限平均粒径为0 . 56 m 。
Following the development of catalytic cracking technology and the increase of refining temperature , this factory cooperates with china petrochemical ( beijing ) design institute to develop a series of refractories with high intensity , good insulation ability and small reheating linear change and good wearproof ability , whose physical and chemical property reaches or surpasses the level of the foreign product of the same kind 催化裂化在炼油装置中地位举足轻重，近年来公司为适应催化、裂化技术的不断发展，设计研制了一系列强度高、隔热性能好、重烧线变化小、耐磨性能高的炼油装置用隔热耐磨衬里，产品理化性能国内领先，甚至达到或超过国外同类产品的指标。
The wearproof refractory for rubbish incinerator is developed by this factory with reference to the foreign preduct of the same kind and the practical working circumstances in china , which has such advantages as good wearproof ability , small reheating linear change and good thermal resistance 垃圾处理行业焚烧炉用耐火、耐磨保温材料是我厂参照国外垃圾焚烧炉用耐火、耐磨保温材料的理化指标，结合我国有关设计应用的实际情况研制开发而成的，它具有耐磨性能好，重烧线变化小，热震稳定性好等特点。
