2results about How to "Lower mixing temperature" patented technology

The application discloses a warm-mixing in-place hot recycling asphalt mixture modifier and a preparation method thereof. The modifier comprises: 90# base asphalt, coumarone-indene resin, waste rubber powder, linear 30 / 70 type SBS, 4,4'-dithiodimorpholine, butyl propionate, poly-alpha-olefin, N-(2-hydroxyethyl)dodecylamide, cocamide propyl betaine and composite release agent. The modifier can reduce the use amount of new asphalt and recycling agent to a certain extent, significantly improve the performance of the recycled pavement and solve the problems of poor low-temperature performance and poor water damage resistance of the recycled pavement. In addition, some additives contained in the modifier have certain surface-active warm-mixing agent characteristics, thereby reducing the mixing temperature and improving the compaction degree of the in-place hot recycling mixture.

The utility model relates to the field of sulfuric acid production, especially relates to a battery sulfuric acid production line, including diluter, carry out secondary mixing with desalted water after mixing concentrated sulfuric acid and battery sulfuric acid once, and output, cooler, its pipe course entrance connects the outlet of diluter, its pipe course export connects battery sulfuric acid storage tank with battery sulfuric acid inlet of diluter, its shell course is connected with cooling water. The utility model solves the problem that the graphite diluter is used in the existing battery sulfuric acid production process, and the graphite and sealing material are corroded by sulfuric acid and enter the sulfuric acid due to the nature and structure of the diluter, which affects the quality of the acid. At the same time, the traditional battery sulfuric acid production process adopts manual operation, which is complicated and not conducive to saving manpower and reducing labor cost.
