Corrosion inhibition process of green compound inhibitors ( CaGL, ZnSO_4 and OCTA) for carbon steel in sea water was studied by electrochemical method ( polarization and EIS). 采用电化学方法研究了自制的高效、绿色复合缓蚀剂(葡萄糖酸钙、硫酸锌和具有多个配位基团的酯类物质&OCTA)在海水介质中对碳钢的缓蚀作用过程。
Large quantity of tetra-through octa-PCDDs and PCDFs, amounting to about 40 percent of the sample wight were found in the waste. Among them, 2,3,7,8-TCDD, the most toxic congener, was also detected. 在热解残渣中检出了大量四至八氯取代的PCDDs和PCDFs,约占样品量的40%,其中包括剧毒的2,3,7,8-TCDD。

Secondly, functional octa ( aminosilsesquioxane) reacted with thermosetting epoxy resin to synthesize uniform hybrid resin, which was cured afterward to obtain organic inorganic polymeric hybrid materials, in which inorganic components bonded covalently with organic matrix and dispersed uniformly. 其次,通过功能性POSS与热固性树脂的反应,合成出均相杂化树脂,然后再对杂化树脂进行固化,得到无机组分与高分子基体通过化学键连接、均匀分散的有机无机杂化高分子材料。
The octa ( nitrophenyl) silsesquioxane ( ONPS)-modified acrylate emulsion is synthesized by a semi-continuous polymerization in this paper. 采用半连续乳液聚合法,将八硝苯基笼型倍半硅氧烷(ONPS)掺入(甲基)丙烯酸酯乳液中,对其进行改性。
The results show that: Octa ( y-chloropropyl) polyhedral oligomeric silsesquioxane ( POSS) with high purity and a symmetrical cage structure were synthesized. 3.3. 测试结果表明:合成出的氯丙基POSS具有笼型对称结构,纯度较高。
