The lowest temperature required for petroleum products to dissolve with an equal volume of aniline to form a single liquid phase is called the aniline point. It is an important indicator for measuring the hydrocarbon composition in petroleum products. The determination of aniline points for both ...
The color of petroleum products is an important indicator for measuring their appearance quality. Different color numbers correspond to the purity, oxidation degree and other characteristics of the product. For example, a too high color number of lubricating oil may indicate oxidation deterioration ...
The smoke point of oils and fats refers to the temperature at which vegetable oils and fats start to produce a small amount of continuous blue-tinged smoke (i.e., thermal decomposition products of oils and fats) when heated to a certain temperature. It is one of the important indicators for ...
The ability index of petroleum and synthetic liquids to separate under specified conditions after being mixed with water is a key parameter for measuring their anti-emulsification performance. The shorter the demulsification time, the better the performance is usually indicated. In fields such as ...
The water content in crude oil is an important indicator for evaluating the quality of crude oil and influencing its processing and transportation. Accurately determining its content is of vital importance to the production and operation of the crude oil industry. The common method for determining ...
The degree of corrosion is a key indicator for measuring the ability of engine coolant to damage metal parts. During long-term circulation, engine coolant will come into contact with metals such as steel, copper and aluminum in the cooling system. If the anti-corrosion performance of the coolant is ...
Engine coolant is a key medium for ensuring the normal operation of the engine's cooling system. It is divided into two types: high-boiling-point and low-boiling-point. Its concentrated liquid may cause corrosion to metal parts during use. The SH0085 engine coolant corrosion tester can accurately ...
The content of mechanical impurities is a key indicator for measuring the purity of petroleum products. It refers to solid or semi-solid impurities in petroleum products that are insoluble in specified solvents. These impurities may cause equipment wear, clog oil circuits, and affect the performance ...
Solid or semi-solid impurities that may exist in petroleum products and additives, such as sand, metal debris, carbon slag, etc., can affect the performance of oil products, such as blocking oil passages and accelerating equipment wear. Their content needs to be determined through specific methods. ...
Liquid density is a key physical property of petroleum products, directly affecting the measurement accuracy during storage and transportation, as well as the product classification during production fractionation (such as fuel quality calculation, different density components corresponding to ...
This type of semi-automatic density measurement equipment used for crude oil detection in the petroleum industry has the core function of accurately measuring the density of crude oil, liquid petroleum products and some chemical products, providing key data support for quality inspection and ...
The content index of acidic substances in transformer oil, expressed as the milligrams of potassium hydroxide required to neutralize 1 gram of oil sample (mgKOH/g), is an important basis for judging the oxidation degree, corrosiveness of the oil and whether it needs to be replaced. By measuring the ...
