These indicate that magnetic composite particles SiO2 / (γ-Fe2O3-SiO2) added in the synthetic process do not affect the structure of synthetic products. 2.2 SEM analysis of magnetic 4A zeolite molecular sieve.
This shows that in the process of crystallization, adding SiO2 / (γ-Fe2O3-SiO2) will not change the frame structure of molecular sieve. 2.4 TG analysis of magnetic 4A zeolite molecular sieve.
It can be concluded by XRD, SEM, IR, TG and other tests found that magnetic carrier of SiO2 / (γ-Fe2O3-SiO2) added in process of the zeolite synthesis does not affect the zeolite framework structure and thermal stability.

As seen in the figures, the morphology was granulated structure when the concentration is 8 mg/ml.
When Mw of PEO is 0.5×106 g/mol, the resulted fibrous membrane is uneven and has the spindle portion structure.
Thereby the some of fibers are uniform forming and with the spindle structure [18].

The formation mechanism and the structure characteristics of the coating were analyzed.
One is modifying micro/nano grade rough solid surfaces with low surface energy material; another is structuring micro-nano rough structure on the surface of low surface energy materials.
This rough structure is caused by the size of nano silica particles themselves.
This means that the coating has a micro-nanometer level of dual rough structure.

Introduction Corrosion protection of steel reinforced concrete structure frequently exposed to chloride environment can be lost due to the ingress of chloride ions.
The addition of admixture especially silica fume can have a very significant effect on the pore solution chemistry of concrete which results in lower pore water conductivity [2, 3].

Preparation of Cement Water Reducer of Modified Lignosulfonate Xiuwen Wu1,a, Heng Zhang2,3,b 1College of Chemistry and Environmental Engineering, Dongguan University of Technology, Dongguan,Guangdong 523808, China 2School of Chemical Engineering ,Qingdao University of Science & Technology, Qingdao, Shandong 266042, China 3Jiangsu Provincial Key Laboratory of Pulp and Paper Science and Technology, Nanjing Forestry University, Nanjing, Jiangsu 210037, China a, bhgzhang@qust.edu.cn Keywords: Lignosulfonate; water reduction agent; synthesis Abstract: In this paper, the cement water reduction agent from modified lignosulfonate was synthesizd using a new process consisting of pre-oxidation, hydroxymethylation and sulfonation.
This can be explained by the increase in lignin reactivity, as its three-dimensional network structure was destroyed by antioxidants, creating more accessibility, which led to reaction with sulfonic group.
