introduction： The production process and formula of grease The production of grease involves two aspects，one、Must have a reasonable formula system，two、It is necessary to have strict and feasible production technology and production equipment that can be easily controlled，The production of grease is sometimes more important than the formula，The same formula may be produced differently in different reactors，Convection temperature，Rate of warming，Charging time，The cooling should be strictly controlled，Theres a lot of difference between that and lubricants ，And the production process of different types of grease varies greatly， Grease production process The process includes：Raw material handling、Saponification reaction、Heat up

introduction： What are fog lights?Hefei electromagnetic clutch and you to understand the next。 The anti-fog light is installed in the front of the car slightly lower than the headlight，It is used to illuminate the road when driving in rain and fog。Because visibility is low in fog，The drivers line of sight is restricted。The light increases the running distance，In particular, the light penetration of the yellow anti-fog lamp is strong，It improves visibility for drivers and surrounding traffic participants，Enable incoming cars and pedestrians to spot each other at a distance Red and yellow are the most penetrating colors，But red means“No access”，So I choose yellow。 Yellow is the purest color，Its also penetrating

introduction：When the metal comes into contact with the surrounding medium，The destruction caused by chemical and electrochemical action is called corrosion of metals。From a thermodynamic standpoint，Except a few precious metals(Such asau、pt)outside，All kinds of metals have a tendency to change into ions，That is to say, metal corrosion is a spontaneous, universal phenomenon。After the metal is corroded，In appearance、There will be changes in color and mechanical properties，Damage equipment、Pipeline leakage、Product contamination，Resulting in serious accidents such as combustion or explosion and serious waste of resources and energy，The national economy suffered huge losses。It is estimated that，The developed countries of the world are caused by metal corrosion every year
