Agricultural urea N46 46% Properties of urea Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 â?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present. Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �³ï¼? The melting point is 132.7 â??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 â?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 â??ï½? 160 â?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 â??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption. Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces. The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made. New standard GB/T2440-2017
CASå?·:57-13-6 Urea for vehicles, agricultural urea, urea N46ï¼? When the temperature of urea is below 20 â?? and the relative humidity is below 70%, it will not only not absorb moisture, but also evaporate water and reduce its water content; When the temperature exceeds 20 â?? and the relative humidity is higher than 80%, it starts to absorb moisture, and becomes paste when it is serious. When the air is dried again, it will re agglomerate, which is only inferior to ammonium nitrate. When the urea aqueous solution is at 80 â??, hydrolysis and decomposition reactions will occur, forming ammonium carbamate, ammonia gas and carbon dioxide respectively. Under acid and alkaline conditions, urea will decompose faster when it is heated. Urea is easy to combine with straight chain carbohydrates to form crystalline additional compounds; It forms a variety of double salts with various inorganic compounds, such as Ca (NO3) 2 �· 4CO (NH2) 2, NH4Cl �· CO (NH2) 2, CaChemicalbookSO4 �· 4CO (NH2) 2, MgSO4 �· 4CO (NH2) 2 �· 3H2O, Mg (NO3) �· 4CO (NH2) 2 �· 2H2O, etc; It is easy to form urea phosphate, dicalcium phosphate and water with monocalcium phosphate, namely Ca (H2PO4) 2 �· H2O+CO (NH2) 2 â?? H3PO4 �· CO (NH2) 2+CaHPO4+H2O; With nitric acid, it is easy to form urea nitrate, CO (NH2) 2+HNO3 â?? CO (NH2) 2 �· HNO3, which combines and relaxes the two; It can combine with formaldehyde to form urea formaldehyde compounds (uric acid rubber shrinks), in which the higher proportion of formaldehyde is urea resin, and the lower proportion is slow-release (effective) urea.
There are two main types of aviation fuels used by airlines around the world: aviation gasoline and jet fuel, which are suitable for different types of aircraft engines. Aviation gasoline is used as fuel for piston type aviation engines. Due to the fact that jet fuels commonly produced and widely used both domestically and internationally belong to the kerosene type, they are commonly referred to as aviation kerosene, abbreviated as aviation coal.
Diesel is a light petroleum product, a complex mixture of hydrocarbons (with a carbon atom number of about 10-22), used as fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced through shale oil processing and coal liquefaction, and can be divided into two categories: light diesel (with a boiling point range of about 180-370 â??) and heavy diesel (with a boiling point range of about 350-410 â??). Widely used in large vehicles, railway locomotives, and ships. The most important use of diesel is for diesel engines in vehicles and ships. Compared with gasoline engines, diesel engines have higher thermal efficiency and lower fuel consumption. Diesel has low energy consumption, so some small cars and even high-performance cars have switched to diesel.
Application of nitrocellulose Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.

We manufacture TYA series vacuum lubricant oil purifier, which can well recovery kinds of waste industrial lube oils, such as hydraulic oil, gear oil, heating oil, compressor oil, machinery oil etc. Why we need recycle the waste lubricant oil? Re: As the resource of petroleum is very valuable and quite limited in the world, besides, as the quantity of petroleum resource is reducing, the oil price is going more and more higher, so we must pay more attention for recycling the used and waste lubricant oils, and find the way to reuse it. What can TYA series oil purifier do on waste lubricant oils? Usually, most waste lubricant oil just contaminated with water, gases and kinds of impurities when it was used on machines, some are emulsified and change its color into white, looks abnormal from new oils. Anyway, this kind waste oil still can be reused after purified with our TYA series oil purifier. It adopt advanced technology for combination of coalescing separation and vacuum dewatering, to get the high precise of water and gas content. Using distinctive removing impurities system, filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power, can ensure the cleanness of purified oil reach NAS6. What else advantages of TYA series compare with other kinds vacuum models? First, it is applied unique demulsification system adopted Japanese H.P.M demulsification devices that are made of high-molecule polymeric material, which can demulsifying the waste lubricant oil more effectively; Second, the application of bi-infrared liquid level autocontrol system and a trio of interlocked preventive devices will ensure you the safefy of TYA operation; Last, it designed with trapezoidal, spiral,automatic back flushing system, it can wash dirty filter element automatically after some time operation, no need to take the filter element out for cleaning, and the filters are not one time use, but can use for very long time, which will greatly save your cost.
