Þróun nanómetra dufts og nanómetra efnis er mjög hröð. Frá upphafi árs 2001, Huaxin Super Hard Abrasives Co., LTD., hefur fyrirtækið útvegað röð af nanódufti. Undanfarin ár hafa viðskiptavinir okkar verið ánægðir með duftformið sem við bjóðum upp á. Aðal FRANGE inniheldur hástyrkt demantur ör duft, nanó ör duft og annað nanó ör duft.
The preparation of nano powder can be roughly divided into gas phase method and liquid phase method. The vapor deposition method includes chemical vapor deposition (CVD), laser chemical vapor deposition (LCVD), vacuum vapor and electron beam and ray beam sputtering. Its disadvantage is higher equipment requirements, large investment. Liquid phase methods include sol-gel method, hydrothermal synthesis method and co-precipitation method, etc. Sol-gel is widely used for the following reasons: (1) Simple operation, short processing time, no extreme conditions and complex equipment; (2) By mixing each component at the molecular level in solution, various nano-powders with complex and uniform composition can be prepared; ③ Strong adaptability, not only can prepare powder, but also can be conveniently used to prepare fiber, film, porous carrier and composite materials.
Sol-gel aðferð er að undirbúa nanó duft eða þunnt filmu með sol-gel - þurrkun - hitameðferðarferli með því að nota lífrænt málmefni (eins og alkýð) eða ólífrænt salt sem hráefni með vatnsrofi, fjölliðun og öðrum efnahvörfum í lausn.
Aðferðir í lausn fela í sér vatnsrof og fjölliðun á lífrænum málmefnum
Hydrolyze M(OR)x + xH2O -- M(OH)x(OR)n-x + xROH
Micro - and nano-technology plays a very important role in the field of fine chemicals. This book is guided by the theory of micro and nano technology. The preparation technology of micro/nano powder, micro/nano technology and coating, micro/nano technology and catalyst, micro/nano technology and adhesive in fine chemical industry were introduced respectively. Micro - and nano-technology and information chemicals and daily chemicals. Micro/nano technology and functional polymer materials, micro/nano technology and fine ceramics, micro/nano technology and medicine, micro/nano technology and food and health care products, and micro/nano technology and pesticides, dyes, additives, etc.
