Determination and control of color in plastic molding (II)

2. SP series portable integrating sphere spectrophotometer

sp62 can provide the absolute value and phase difference value of the following colorimetric system. The value is mainly expressed by 9 standard light sources, and the observer's angle is: CIE XYZ, CIE YXY, CIE LAB, Hunter Lab, CIE LCH (l*c*h is calculated by ab or UV colorimetric space), CMC and CIE94, whiteness and yellowness in ASTM E, isochromatic heterospectral index and din6172

sp62 can measure opacity and intensity of three colors (appearance, chroma and tristimulus). In addition, sp62 also has 555 color light classification function for textile. This measurement is helpful to the color quality control of plastic, coating or textile products

sp62 simultaneous measurement includes specular reflection (true color) and excluded specular reflection (surface color) data to help analyze the influence of sample surface structure (mirror) on color

sp62 stores 1024 standard continuous tolerance settings to facilitate qualified/unqualified measurement, and sp62 will sound the unqualified results. The response time of the instrument is fast, and the measurement time of each sample is about 2S

sp62's fuselage structure is mainly designed for user convenience and conforms to ergonomic principles. The built-in operating procedures help users use the instrument. The red/green LED display lamp and large screen display make the data easy to read. Wrist strap and hand-held body design ensure comfort and accuracy when using

3. Premier 8000 Series benchtop spectrophotometer

this series is a bench top spectrophotometer, which can easily transmit and display the measurement. If the measurement is incomplete, it should be installed with a new gasket attached to the machine to prevent oil leakage data and capture images under high pressure. The first built-in CCD digital target positioning system allows users to directly and easily preview the target positioning through the computer screen and make adjustments

the instrument has a wide transmission measurement space, which can accommodate large samples. In addition, there are different sizes of sample containers and fixtures to choose from, and the measurement results can be obtained quickly and accurately without special adjustment. This transmission spectrum measurement can be used for translucent or fully transparent plastics, glasses, dyes, petroleum or other liquids

8400 model provides excellent inter platform difference of instruments, and its data can be exchanged with X-Rite SP series portable spectrophotometer, so that all departments of the enterprise can share measurement data and strengthen communication, so as to realize the integration of company standards. It can also be configured with UV chips at will to control the UV content of the measurement light source, so as to measure the color of samples sensitive to UV light

the built-in integrating balls of this series all adopt Spectralon? Carved from materials. Spectralon? It is an uncoated and durable high reflective material, which will not corrode, peel off or turn yellow with time, so it eliminates the time and cost of recoating, and can get the best reflection and measurement data at the same time. The built-in optical pure glass sheet in the light source part of the transmission measurement chamber can prevent the bulb, receiver and electronic parts from being damaged. In addition, the integrating sphere measuring protective mirror can be selectively used to prevent the damage of the instrument due to the splashing of liquid or powder during the upper measurement

8000 series is the world's first desktop fractional spectrophotometer connected with USB interface, which is plug and play, convenient to operate and can speed up data transmission. It is used to measure fluorescence and whiteness by cooperating with iseli software, so as to simulate the fluorescence and whiteness data of other spectrophotometers, strengthen the data exchange between users, and help users control fluorescent substances

8000 series can be connected. If the authoritative appraisal result is obvious, connect x-ritecolor? MAS high nickel 3 yuan is the king ter software series to provide quality inspection and computer color matching functions. The software allows users to store commonly used instruments and set the interface for use at any time

4, ma68 Ⅱ portable multi angle spectrophotometer

this spectrophotometer is an ideal measuring instrument for various metallic gloss, pearl gloss and special gloss of plastic processing, injection molding and extrusion molding products. The instrument can provide five angles (15, 25, 45, 75110) to measure and calculate the colors of various gloss emitted by objects, such as metallic gloss, pearl gloss and special gloss. X-Rite adopts dynamic rotating sampling technology to measure the color of the sample from multiple angles at the same time

5. Color expression and product quality control of X-Rite system

x-ritecolor master software is an application software based on Windows operating system, which is characterized by simplicity, convenience and strong operability. There are two different versions - x-ritecolor? Master quality assurance software and x-ritecolor master formulation software. The former monitors and maintains the color quality of the whole supply chain, while the latter determines the fixed or minimum amount of opaque, translucent or transparent colorants. All x-ritecolor master software is jointly completed with the participation of professional designers of color measuring instruments

combining these two versions of software can form the network version of x-ritecolor master. It is an application software based on server environment. X-ritecolor master Web edition can run on any server in the world. Users can use the existing network system of the company. Local area, wide area and Internet can meet the requirements of x-ritecolor master Web edition software. If necessary, x-ritecolor master Web edition also has a global color standard database interface. Authorized professionals can change the software settings and color standards on the central server to ensure that the data of the whole supply chain is updated at the same time, which ensures the accuracy of the software data running on each computer, and saves the time and money spent updating the data

x-ritecolor master Web edition can run seven languages at the same time. In a word, the X-Rite color measurement system enables the formulation designer to easily obtain color information with minimal effort. Quality control personnel can also easily inspect whether raw materials and products meet the requirements of product standards
