How to make the correct colorimeter is a kind of instrument for measuring the color of objects. Also known as color difference meter, color difference meter, domestic color difference meter, color difference analyzer, color difference tester, fine color difference meter, color difference detector, color difference meter, portable color difference meter, color difference calibrator, color difference measuring instrument, pigment color difference meter Wait.
Actively compare the color difference between the sample and the tested product, and output the CIE_Lab three sets of data and the color difference data of â–³L, â–³a, â–³b, â–³E after colorimetry, after all, look at the total color difference of â–³E value. the difference. Electronic balance BR>
The bar coater is second, accounting. According to the internship accounting of the company or the company, it is still domestically made to buy imports. If you think that you are satisfied with your own accounting and are interested in imported products, you can think about importing. After all, it is not your fault! If you are interested in the domestic colorimeter, you can learn more about it. After the domestic colorimeter has been opened for so many years, it is completely comparable to the US imported color difference meter. The more important thing is that the price is much better than the imported one, and the imported color difference meter has a long after-sales service. The high cost, which is also the factor for the company's selection of domestic colorimeter in these years.
Finally, the functional equipment of the high and low temperature test chamber color difference meter!
1. You need to know which colorimeter is suitable for your job. The accuracy requirement for color difference is different for each job, that is, â–³Eab. If â–³Eab is between 0-1, then you need to select higher precision. Instruments; these are usually rubber and plastic, paint and spray paint for the centrifuge industry; if you do not need precision, you can pick the usual color difference meter.
2, you have to understand the shape of your product, nowadays the inspection aperture of the colorimeter is usually 4mm or 8mm or 16mm; there are also some special operations, such as the Academy of Agricultural Sciences often choose 40mm caliber. Different calibers are available.

Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
