First, choose fabrics - the common common fabrics are printed cloth, dyed cloth, yarn-dyed fabric, printed cloth four types
1) The printed cloth is printed on the plain fabric by transfer or garden net. The color is called a printed cloth. Its characteristics are colorful and rich in patterns. It has a hand-painted printing effect and reveals a natural texture.
2) The color of the dyed cloth dyed on the white fabric is called dyed cloth. Its characteristics are elegant, natural and stiff.
3) According to the pattern needs, the yarn-dyed fabric firstly sorts and dyes the yarn, and then interweaves to form a color pattern called yarn-dyed fabric. Its characteristic color fastness is strong. The color-dyed texture is distinct and the stereoscopic effect is strong.
4) The printed fabric combines the two processes of jacquard and printing to be called a printed cloth.
Second, choose the color - the color is warm and cold, the depth of the points. The criteria for selecting colors are as follows
1) Color and room decoration color: When comparing fabrics, you can bring some scraps with you.
2) Color and wood products in the room: The color of the fabric can enhance and enrich the natural color of wood products.
3) Colors and emotions: light and soft tones, neutral tones and cool tones, such as blue and some green to calm, bright tones and warm colors, such as red and yellow, stimulating, dark Feel warm and comfortable.
4) Color and feeling: It feels that the light color is the background to make the color darker, the dark background makes the color lighter, and the warm color makes the object appear smaller. In short, smaller rooms are not available in two distinct colors.
5) Color and room orientation: The warm color makes the north facing room feel warmer, and the cool color makes the south facing room feel cool.
6) Color and stain resistance: Lighter colors are more likely to appear dirty than dark colors.
7) Color and Transmittance: Light-colored light has a strong light transmittance, which can be diffused through the window cloth in the room, and the dark-colored light has a weak light-blocking effect.
8) Color and personality: According to the above principles and personal preferences to choose colors and reflect personal style.
Third, choose the flower type - the flower type has the size of the size to choose the flower type mainly according to the size of the room.
1) Large room size can choose larger pattern: it gives a strong visual impact, but it will make the space feel smaller.
2) Small rooms should choose a smaller pattern: it feels warm, quiet and makes the space feel wider.
Alnico Magnets are traditionally classified using numbers assigned by the Magnetic Materials Producers Association (MMPA), for example, Alnico 3 or Alnico 5.
Alnico magnets are produced by casting or sintering processes.[8] Anisotropic alnico magnets are oriented by heating above a critical temperature and cooling in the presence of a magnetic field. Both isotropic and anisotropic alnico require proper heat treatment to develop optimal magnetic properties-without it alnico's coercivity is about 10 Oe, comparable to technical iron, which is a soft magnetic material. After the heat treatment alnico becomes a composite material, named "precipitation material"-it consists of iron- and cobalt-rich[9] precipitates in rich-NiAl matrix.
Alnico's anisotropy is oriented along the desired magnetic axis by applying an external magnetic field to it during the precipitate particle nucleation, which occurs when cooling from 900 °C (1,650 °F) to 800 °C (1,470 °F), near the Curie point. Without an external field there are local anisotropies of different orientations due to spontaneous magnetization. The precipitate structure is a "barrier" against magnetization changes, as it prefers few magnetization states requiring much energy to get the material into any intermediate state. Also, a weak magnetic field shifts the magnetization of the matrix phase only and is reversible.
Alnico magnets are ideal for high temperature applications up to 550ºC
. Cast Alnico Magnet is very stable, has good corrosion resistance and a typical hardness of 50 Rockwell C. Once cast, the material is so hard that the only machining possible is grinding
. Cast Alnico Magnet represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.
