Method for preparing high-performance PAL (phenylalanine ammonia lyase) material by using non-metallic mineral palygorskite

Abstract

The invention specifically discloses a method for preparing a high-performance PAL (phenylalanine ammonia lyase) material by using non-metallic mineral palygorskite, which is characterized in that the method is implemented by using a flexible crushing principle and a flexible crushing technique, as well as no-drug high-speed liquid flow depolymerized dispersion, separated purification and concentration processes, and crushing, superfine milling, purifying, drying and classifying processes. The deeper meaning of the high performance of the PAL material is embodied in the level of physical scientific research, namely, crossing the boundary of living matters and non-living matters, therefore, the method disclosed by the invention provides a support for new revolution of life science, material science and energy science.

Description

technical field [0001] The invention relates to a method for preparing high-performance PAL material by using non-metallic mineral palygorskite. Background technique [0002] There are usually two ways to prepare micro-nano powders: one is to obtain fine powders by crushing large-size bulk materials, which is called the pulverization method. The particle size is basically around 3 μm; the second is to control the crystal nucleation and growth conditions to obtain micro-nano materials of specific sizes, which is called the nucleation growth method. Different approaches mean differences in theory and technical principles, and the physical and chemical properties of the resulting microparticles are also different. Therefore, product performance and economic factors are the basic requirements for choosing a preparation route. Based on the above requirements, at present, two processes of superfine pulverization and fine classification are generally used in the preparation techno...

[0015] However, with the mechanical method, its size can generally only reach the level of about 3 μm. Although the nucleation growth method can obtain ultrafine particles of a specific size (greater than 5nm and smaller than 100nm), it is basically based on chemical reactions, or nucleation The growth conditions are harsh, and some technical processes are not yet mature

Especially for the preparation of special granular micro-nano powders with special functions and high product added value, and the recovery and utilization of polymer materials and polymer composite materials with huge markets, there are ultra-fine crushing equipment for these tough materials Obvious insufficiency has become a technical bottleneck
