Plastic extinction method including the reasonable selection of resins and additives, control of mould extinction and surface roughness, surface coating machinery extinction, etc.
Injection molding products processing of extinction is the opposite of plastic lighten the method, the modified purpose is to reduce plastic products surface gloss.
General to make its gloss drop to below 15%, only then may call it the surface of extinction.
In order to make the human eye has a comfortable, people need to extinction surface in some occasions.
plastic surface coating extinction method this method is to choose some low gloss paint coating on the surface of the injection molding processing, can choose electrostatic spraying coating method, etc. , in addition, can also use a metal coating method by light, the surface has the following process.
1。 Substrate processing, can use sandblasting processing, rolling mill, polishing brush processing and chemical processing, etc. , make the matrix presents for sand surface state. 2. Soft light paint, spraying soft light coating and electrophoretic anode or cathode light coating, etc.
forming die roughness control size of forming mold surface roughness is the main factor to plastic products surface gloss. Extinction products require mould surface roughness is high, generally to sandblasting processing, to improve its surface roughness. Sandblasting sand powder is silicon carbide, quartz sand, alumina and silicon carbide, and so on.
plastic transparency, transparency of measure of a material is good or bad, there are many performance index is to consider, the commonly used indicators are: light transmittance and fog degree two main characterization of pervious to light quality indicators, and the index of refraction, double refraction and dispersion of three indicators are mainly used for characterization of the pervious to light quality.
light transmittance is defined as: the luminous flux through the material with the incident to the percentage of the ratio of the flux on the surface of materials.
light transmittance is representing the degree of resin transparent one of the most important performance indexes, the higher the light transmittance of a resin, its transparency, the better. Either the light transmittance of transparent materials amounted to less than 100%, even if is the best of the transparency of the optical glass light transmittance generally are no more than 95%.
the incident to the luminous flux of the polymer was not through no reflection part of luminous flux is the absorption of light. Light scattering light is incident to the polymer surface, not through - and no part of the reflection and absorption, luminous flux, it occupies small proportion. The cause of light scattering to the polymer structure uneven. Usually only crystalline polymer scattering is more serious.
haze can measure a transparent or translucent material is not clear or cloudy. Haze is a result of a material caused by internal or external light scattering nebulee or the appearance of turbidity. Haze is defined as: a material scattering luminous flux and through the percentage of the ratio of the material flux.
refraction that is the difference between the incident light and the light direction. To measure the size of the material refractive, usable and refractive index. The more severe the refraction of the refractive index, the greater the material. As the lens and use resin, hope its refractive index. Refractive index is larger, the thickness can be reduced accordingly.
birefringence is parallel direction and vertical direction of the material refractive index difference of refractive index. The larger the birefringence, the easy to cause the image produce the phenomenon such as crooked shadow. So says the birefringent optical material of pervious to light quality, should try our best to reduce the injection molding processing material birefringence. Material has double refraction phenomenon, is mainly due to the resin molecular structure and molecular orientation from two aspects.
