Temperature change color in a short time can be resistant to 230 high temperature (about 10 minutes), it can be used in injection molding and high temperature curing. However, the thermal stability of color pigment in hair color and the achromatic state status is different, the stability of the former than the latter. In addition, when the temperature is above 80degree composed of organic matter color system will begin to degrade. Therefore, color pigments should avoid long-term work at temperatures above 75degree under.
2, heat resistance:
Light poor temperature change color pigment in the strong sun exposure can fade quickly under fail, so it is only suitable for indoor use. Avoid strong sunlight and ultraviolet light irradiation, which will help extend the life of color pigments.
1, the light resistance:
Reversible temperature-sensitive color pigment itself is an unstable system (stable it is difficult to change), so its light, heat, anti-aging properties far less than ordinary paint, in use should be noted.
E: in the formulation of PVC resin should avoid the use of phosphorus-containing stabilizer and plasticizer, otherwise it would have serious discoloration injection-molded articles residual color upon achromatic state.D: You can not use mixer, kneader, high-speed dispersion machine, twin-screw extruder of high shear mixing equipment for pre-plastic particles and color pigment. These devices can seriously damage the surface of the protective layer pigment discoloration, loss of color performance. In addition, the preparation of a pigment color masterbatch should be avoided subjected to repeated extrusion granulation.C: carefully chosen crosslinking agent or curing agent: crosslinking curing epoxy resin and unsaturated polyester resin, which sometimes have a strong internal shrinkage stress, resulting in pigment discoloration microcapsule shell rupture, other chemicals into pigment inside it lost color performance. This situation often occurs when the thickness of the cured epoxy is greater than 0.2 mm and the use of multi-amine curing agent.B: casting, molding, curing the first color should be used with pigment color pigment added to unsaturated polyester, acrylic or nylon within a single body stirred and dispersed evenly, then add the initiator or curing agents to initiate polymerization or crosslinking reaction. Because of the sharp increase in the viscosity of the system to gather after this time will make a lot of added color pigment pigment particles packed together, difficult to disperse evenly. In this case, the stirring operation will also make the system a lot of residual bubbles.A: When using injection molding and extrusion of plastic paint color should no longer use other fillers or ordinary paint (for example: titanium dioxide, calcium carbonate, barium sulfate, carbon black, etc.), otherwise it will shield color effect.6 Note: The processing temperature should be controlled below 200degree the maximum should not exceed 230degree, heating time and minimize material. (High temperature, prolonged heating will damage the color properties of the pigment).5, temperature: When mass production can be first color pigment into the polyethylene wax or wax made of polystyrene pigment content of 10% of the masterbatch, and then mixed with plastic particles. This allows the color pigment dispersed more evenly. Masterbatch production method may refer to the technical information provided by the Division.4, masterbatch:3, for injection molding, extrusion molding or machining, molding, curing time, color pigment is used in an amount of 0.4 to 3.0% of the amount of plastic, generally 0.6 to 2.0%. Color pigment and plastic particles to fully mixture evenly (you can use a small amount of white oil mixed). If an ordinary paint and color pigments mixed colors, the ordinary pigment (or dye) in an amount of about 0.5-2.5% color pigment.2, can be used in polypropylene (PP), flexible PVC (S-PVC), AS, ABS and silica gel transparent or translucent plastic injection molding, extrusion molding. It can also be mixed with unsaturated polyester, epoxy, acrylic or nylon single-body casting, molding, curing of inks suitable substrate.
1, temperature change is microencapsulated powder reversible temperature change substance called reversible temperature-sensitive color pigments (commonly known as: temperature change color, temperature or temperature change powder powder).
Second, the temperature change powder Application:
3, the temperature change product design to color change at low temperature and high temperature environment for the demands of the environment and human body temperature is mostly used in products, but also can use the security design.
2, temperature change color microcapsules containing particles in the size range 1 ~ 10UM, and has a high temperature, oxidation and other changes in the characteristics of the capsule.
1, temperature change with increasing temperature can be decreased repeatedly will change color. (31degree to red, for example, more than 31degree color in the form of a colorless presented below 31degree is red).
Microencapsulation reversible temperature change substance called reversible temperature-sensitive color pigments (commonly known as: temperature change color, temperature or temperature change powder powder). This pigment particles are spherical cylindrical, with an average diameter of 2 to 7 microns (a micron is a thousandth of a millimeter). Its interior is discolored material thickness of the outer layer is 0.2 to 0.5 microns can neither dissolve nor melt the transparent shell, it protects it from erosion discoloration substance other chemicals. Therefore, to avoid the destruction of this crust is important in use.Temperature change pigment type organic compound by the electron transfer system prepared. Electron transfer-type organic compound is an organic chromophore system has a special chemical structure. At a specific temperature by electron transfer of the organic molecular structure is changed, in order to achieve color change. This discoloration substance not only colorful, but also from a "colored === colorless" state of the color change, which is a heavy metal complex salt complex type and liquid crystal type reversible temperature change of substance are not available.
