Our company is a manufacturer specialized in providing carburant for a variety of products. Today, the small editor will introduce to you the inspection rules of carburant, hoping to be helpful to you. Let's have a simple understanding: The size specification of carburant can be divided into 0-1mm, 0-5mm, 0-10mm, lmm-4mm, 4mm-10mm, etc. according to different application requirements, and the size requirement can also be directly put forward to users. The appearance requires purity and no impurities, and of course there are some physical and chemical standards. So how to identify The advantages and disadvantages of carburant or the inspection shall follow the rules. First of all, the inspection and acceptance of carburant should be carried out by the technical quality supervision department.   Then, it involves the adoption of debris. Bagged products are sampled according to the system sampling method. That is, each bag in the additional products is separated according to a certain sequence, one bag is randomly selected from 1 to N bags of products for sampling, and then one bag is drawn every n- 1 bags for sampling, the sampling amount in each bag is the same, and the samples taken are combined and mixed evenly as samples of the batch of products. The number of sampling bags is calculated according to the formula: x = n/100, where: n-the number of bags in each batch of products; X-number of bags taken per inserted sample. When x is calculated with decimal, the decimal part shall be omitted, and when N≤100, samples shall be taken from each bag. When sampling, insert the sampling hole into the bag and take it out. The sampling quantity of each batch shall not be less than 1kg. A small amount of preparation Pour the sample onto a square plastic film or soft paper or cloth with sufficient strength and appropriate size, and mix evenly by tumbling (tumbling for more than 15 times). Use the quartering method to reduce 500g of small packaged products with packing specifications to a part every 100t, and calculate according to distribution if one delivery is less than 100t; Large packaged products are separated every 250t, and those with less than 250t delivered at one time are calculated according to the budget. However, each batch of carburant products should be analyzed and tested for physical and chemical indexes.    If the unqualified carburant is not qualified in the inspection, double sheets shall be taken for the unqualified items to be inspected. If the inspection is still unqualified, this batch of products shall be treated as unqualified products. With great confidence and enthusiasm, we will join hands with our partners who have always given us great support and help to create brilliant future. We will also be willing to create a win-win situation with you and our new friends through sincere exchanges and mutual trust.

Carburizing agent, commonly known as carborundum, is a ceramic compound formed by bonding silicon with carbon. Carburizing agent silicon also exists rare mineral in nature, mosanite. The common method is to mix quartz sand with coke, add salt and sawdust, place in a low nitrogen carburant electric furnace, and heat to a high temperature of about 2000 c. Edward Goodrich Acheson made the compound in 1893 at the price of carburant and developed the Acheson electric arc furnace for producing silicon carbide, which is still in use today. Silicon carbide has at least 70 crystalline forms. Alpha-silicon carbide is the most common isomorph of carburant manufacturers. It is formed at a high temperature higher than 2000°C and has a hexagonal crystal structure (like wurtzite). Beta-silicon carbide, cubic system structure, similar to diamond, is generated at less than 2000 C. The structure is shown in the page diagram. Although the application of heterogeneous contact calcined coke carrier is attractive because it has a higher unit number than the α type, up to now, this type has not been commercially applied. Due to its specific gravity of 3.2 and high sublimation temperature (about 2700°C), silicon carbide is very suitable as a raw material for bearings or high temperature furnaces. Under any pressure that can be reached, it will not melt and has relatively low chemical activity. Due to its high thermal conductivity, high breakdown strength and high maximum current density, a large number of people have recently tried to replace silicon with it in the application of semiconductor high power components. Therefore, it has a strong coupling effect with microwave radiation, and all its high sublimation points can be reset to actually replace the heating metal. The iridescent luster on the crystal is caused by the silicon dioxide protective layer produced on its surface. Used in semiconductor, lightning rod, circuit element, high temperature application, ultraviolet detector, structural material, astronomy, disc brake, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tool, heating element, nuclear fuel, jewelry, steel, protective gear, catalyst carrier and other fields.
