The Technical And Economic Analysis & Research For One Kind Of New Organosilicon Water-repellent

This topic belongs to the new material development and the application domain. The organosilicon water-repellent and base material's reaction time is long, the toughness of becoming membrane not good, and its ability of bearing the climate is not so good. When spread outside the organosilicon's permeability is bad, and its alkalinity is high, In particular regarding the wide crack, the effect of repairing is very bad. Moreover, its synthesis craft is complex, cost high, and the factor of price compared to status is low. In view of its shortcomings, this topic carries on the modification to the traditional organosilicon water-repellent, develops one kind of the new modified organosilicon waterproofing coating, which has solved the problems that the cost of repairing is high, after service, the duplicate leaking rate is high, the effect of materials used in repairing the waterproofing is not good, etc, in the army and the place house leakage service. The practical application in projects has further confirmed this material's military economic efficiency. Main achievements:Proposed the unique technical route: Distinguishes in the traditional organosilicon modified acrylic acid (ester), this research technique uses the acrylic acid (ester) to modify the organosilicon. Looks up newly through the science and technology, no report has been seen in domestic and foreign using this technical route to conduct the organosilicon modification research.Synthesized the modified organosilicon water-repellent: this topic uses the acrylic acid series monomer to carry on modified processing to the many kinds of organosilicon, introduces the hatred water factors, chooses appropriate modifier, the emulsifier and the synthesis condition (for example, the temperature, the pH value and so on) ,has synthesized the modified organosilicon water-repellent having fine waterproof performance.In this paper, the total investment of the modified organosilicon water-repellent has been estimated. After that, according to the financial appraisal basic principles, the financial appraisal analysis to the existing three plans has been carried on. The synergy is using the modified organosilicon water-repellent which is researched and developed by this this topic to carry on the waterproofing to guard against seepage processing.This paper uses analytic hierarchy process (AHP) to determine the weight of all indicators to assess and test comprehensively the characters of the organosilicon and the modified organosilicon water-repellent. Referring to the empirical datum, after normalized processing, determines esch indicator's mark..The synthetic evaluation to the organosilicon and the modified organosilicon water-repellent has...
