其装置之原理为利用触煤的特殊性质分解有害废气，使其在低温即能完全氧化或转化为无害的气体或水。 - Through the analyzing the macro - structure to micro - structure , the author considers that retarding mechanism of citric acid is that citric acid and ca in the gypsum form the complexant ion , and hinder the crystallization center of dihydrate crystal bigger ; that of sodium tripolyphosphate is that it combined with ca , hinders the dissolve of hemihydrate . formation and growth of crystallization center ; that of bone glue is the glue - protection and chemical absorption action of active group , which also retards the formation and growth of crystallization center
通过宏观到微观的分析，笔者认为，柠檬酸的缓凝作用的原因主要在于柠檬酸与钙形成络合离子，影响了二水石膏晶体的晶核长大过程；多聚磷酸钠与钙形成某种复盐，对于石膏晶体的溶解、成核和长大过程均有强烈的阻碍影响；骨胶则在于胶体对半水石膏的包裹和活性基团的化学吸附，使二水石膏晶体的成核和长大困难。 - 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。
