The steel and iron (Zn) the phosphate surface treatment technical

Abstract

Consults literature understanding phosphorization craft each kind of type before this experiment the good and bad points,but the zinc is the performance is fine is the main direction which at present studies,therefore proposed the zinc is the parkerising takes this research direction.The experiment determined the bonderizing craft each kind of condition,the temperature is 30--500C,the PH value is about 2.8,promoter for nitrous acid coin 0g/L,chemical additive for sodium fluoride 1.0---1.5g/L.Again determines the low temperature phosphorization formula through the orthogonal experiment:The zinc oxide is 8.00g/L,the phosphoric acid is 0.07mol/L,the nitric acid is 0.06mol/L,the nickelous nitrate is the 1.00g/L

The steel( zinc department) phosphoric acid salt surface processing craft

Take off to want

At a merit and shortcoming that experimented to check the cultural heritage understanding 磷 chemical engineering skill various type before,but the zinc department function is good is a main direction study currently,so put forward the zinc department phosphoric acid salt processing conduct and actions to study the direction originally.The certain 磷 of experiment turns various condition of handle the craft,the temperature is a 30-500 Cs,the PH is worth to 2.8 or so,the accelerant is the second sodium nitrate 1.0 gs/ L,the additive turns the 1.0-1.5 gs/ L of 钠 for the fluorine.Pass again just hand over to experiment the assurance the low temperature 磷 turns the formulation:The butter of zinc is a 8.00 gs/ L,the phosphoric acid is a 0.07 mols/ L,nitric acid is 0.06 mols/ L,the nitric acid 镍 is 1.00 gs/ L.

问题5：英语翻译气候变暖已经成为当代人类最关注的环境问题之一,空气中二氧化碳浓度的增加以及生活工业中二氧化碳的排放与全球气候变暖某种程度上有着必然联系.根据当前的社会局面,发展低[英语科目]

Climate warming has become one of the most pay attention to the environmental problems of the contemporary human, increased levels of carbon dioxide in the air and life in the industrial emissions of carbon dioxide and global climate warming has a connection to a certain extent. According to the currentsocial situation, the development of low carbon economy is the trend of The Times.

In this paper, combined with China's low carbon economy development present situation and the characteristics of economic development in henan province, analysis of the development of low carbon economy at home and abroad, at the same time are analyzed in detail the concept of "low-carbon economy", this paper expounds the necessity and the objective inevitability of low carbon economy development in henan province, and puts forward countermeasures and Suggestions in the low carbon economy development of henan province.

This paper is divided into the following six parts:

The introduction mainly wrote a low carbon economy development background and research significance, clarify the causes of low carbon economy development in henan province, the research of low carbon economy development present situation at home and abroad are summarized, and the research contents and methods of this paper for the integrity of the self evaluation. The first chapter expounds the "low carbon economy" concept andconnotation of the term, and the corresponding theoretical basis hasmade the detailed analysis, including environmental kuznets theory,sustainable development theory, the decoupling development theory, ecological theory, laid a theoretical foundation for the next study. The second chapter analyzes the practical significance of low carbon economy development, tells the story of a low carbon economy development and implementation for the economic development of henan province is a very important step. The third chapter earnestly analyzed the current situation of the development of low carbon economy in henan province, start from the energy structure and energy consumption of the province, calculation and analysis of carbon emissions and its influencing factors, provide the theoretical basis for development countermeasures. The fourth chapter according to the current situation of the development of low carbon economy in henan province, compared with the advancedlevel at home and abroad to find their own gap, careful analysis causes the lesson in order to progress. The fifth chapter combines the result of the above analysis and advanced experience both at home andabroad, combined with the economic development in henan province, the feasible countermeasures and Suggestions are put forward.
