Air Impact powder surface modification device

Mixed state to the film state by the process of change. 2.3 The treatment of spherical particles without compound treatment, the use of metal or plastic deformation of resin itself, under the impact, the collision polished into irregular particles are spherical particles, thereby enhancing the mobility of PSO. Adjust the bulk density and surface area. Figure 7a, b is a spherical powder before and after comparison of Bin Bin circle around the mother Sacrificial 0 8, of course,[link widoczny dla zalogowanych], the above three functions is not always alone, and sometimes may also be present in the same process, for example, fixed or film-forming process of treatment, the particles also (hi) Figure 6 of the spherical treatment, shown in Figure 8. The impact of using this method for particle flow speed processing of the main objectives are: (1) Creation of composite materials have some characteristics, (2) saving precious metals or materials, (3) rationalization of production processes, (4) to improve and enhance the kinds of physical and chemical properties of powders,[link widoczny dla zalogowanych], (5) full use of the mother's physical and chemical properties of particles themselves and open up a wider range of applications. 3HYB system operating conditions in theory, using this method can make all kinds of organic, inorganic and metal materials are infinite combinations, in fact, the choice of appropriate material (ie reasonable \can create a satisfactory new materials or improving the particle nature of the key. 3.1 The combination of material combinations of material, we should consider the following factors: (1) best mother particle size 500 ~ m or less (2) the mother particles and child particles in diameter or more than the best for the 10tl (a particle the smaller the better). (3) the mother particles can be spherical or irregular in shape, but the mother of scaly particles or fibrous material, the treatment is difficult, the general shape of the particle pair has no special requirements. (4) for film processing, sub-particles of the softening point, glass transition point and other factors should be key consideration, and sometimes it is very important. (5) Mother, son of particles from the mixed treatment than the general purpose end-use materials must flow impulse given powder surface modification device, in theory, the mother, the child particle mixing ratio determined as follows: z = 7D/47 \\Where z a feed of the best theoretical ratio; one female parent particle density} D {7 sub-particle size and particle density; D {D particle size of a child of a modified particle diameter. In addition, attention should be paid,[link widoczny dla zalogowanych], to meet the requirements of the situation, the economy should be easy to get full use of the emblem of powder materials. 3.2 The operating conditions are also important factors in operating conditions, such as the rotor speed, processing time, mass,[link widoczny dla zalogowanych], temperature, gas environment, and so play a role. (1) speed and the impact on speed,[link widoczny dla zalogowanych], is the main energy source. Poor air circulation speed is too low to handle uneven, affecting the quality of materials, HYB speed characteristics shown in Figure 9. (2) processing time; processing time depends on the length of the general nature of the material being processed, most of the control 5rain around too long and no practical significance, HYB characteristics of the processing time as shown in Figure l0. (3) feeding amount: feeding amount is also one of the main factors, mass non-uniformity of the product was poor, mass of hard to do quantitative requirements, the operator according to the treatment effect itself. (4) processing temperature: the movement of particles in the intense, the particles and mechanical friction between the wall and the particles produce a lot of heat, the use of this effect can be film processing. However, the nature of the material suddenly lOB {6 2O t vend the transferred field 9HYB purpose built properties and processing of the different internal temperature is too high can sometimes backfire, the operation should pay attention to the cooling system using cooling devices, the general control of the temperature In between 40-90 ��.

Deal by resin coating in the form of ceramic, metal, can be prepared by powder injection molding; use of metal-ceramic composite processing, can be prepared by sintering materials.
