introduction： Index for assessing spontaneous combustion of fuel oil。The spontaneous combustion of fuel has an effect on the starting performance and combustion process of diesel engine，It is an important performance index of diesel oil。To determine the spontaneous combustion of fuel，N-cetane with excellent ignition properties(C16H34)Cetane number is100,Prescribed to have extremely poor ignition performance－methylnaphthalene（C10H7CH3）Cetane number is0，Were going to add n-cetane to－Methyl naphthalene is used as a standard fuel in mixtures of different proportions。When the ignition performance of the tested fuel is equivalent to that of a certain proportion of standard fuel，The percentage by volume of cetane in this standard fuel is％when，Thats the subject

introduction：Stainless steel definition A high alloy steel that resists corrosion in air or in chemically corrosive media，Stainless steel has a beautiful surface and good corrosion resistance，No need to go through plating and other surface treatment，And play the inherent surface properties of stainless steel,A type of steel used in many ways，Commonly known as stainless steel。Represents performance are13Chromium steel，18-Chrome-nickel steel and other high alloy steel。 From the metallographic point of view，Because stainless steel contains chromium, it forms a thin chromium film on the surface，This membrane acts as a corrosion resistance to oxygen intrusion from within the steel。 In order to maintain the inherent corrosion resistance of stainless steel

introduction：The setting of injection pressure is mainly to control the oil pressure enough to push the screw to reach the set injection speed requirements。Due to the different characteristics of each plastic，The ease of flow is different，The melting temperature of the same material is different，The viscosity also changes，Different products、Mold design、Different mold temperature will change the resistance formed by the material flow，To be maintained in a variety of conditions Identical exit velocity，I have to change the injection pressure，To overcome the resistance caused by the flow of molten glue。 The injection pressure is different from the holding pressure，Injection pressure mainly affects the filling stage，Maintaining pressure affects the cooling phase。

introduction： Working principle Access to thermal energy in a closed mezzanine（Like hot water、Low pressure steam or thermal oil），Heat is transferred to the material to be dried through the inner shell，Under the power drive，The tank rotates slowly，The materials in the tank are constantly mixed，So as to achieve the purpose of strengthening drying。 The material is in vacuum state，The drop of steam pressure makes the surface of the material water（solvent）It reached saturation and evaporated，And by the vacuum pump timely discharge recovery。Moisture inside the material（solvent）Constantly penetrating the surface、evaporation、discharge，Three processes continue，The material is dried in a very short time。 ,

introduction： Steam turbine that draws steam from the intermediate stage to the heat user。The extraction pressure is determined according to the needs of users and the requirements of product serialization，It can be adjusted within a certain range（See table[Extraction pressure adjustment range（mpa）]）。 According to the number of steam extraction，Extraction steam turbine is divided into single extraction steam and double extraction steam two kinds。The flow part of single extraction steam can be divided into two sections: high pressure and low pressure。The flow part of the double extraction steam is divided into high pressure、Middle pressure and low pressure。Each section has a separate cylinder，The unit cylinder arrangement is formed，Or several segments together in a cylinder，Constitute a single cylinder arrangement。There is a steam extraction port between sections，Some steam is extracted through this opening，The rest by one can
