Temperature Affects Materials Friction Coefficients

The state change of molecule motion of high polymer is called laxation according to the view of dynamics. The rising of temperature can improve heat movement ability of moving units on the one hand. On the other hand, because of thermal expansion, it increases molecule distance. Namely the internal freedom volume within the high polymer increases, which can increase activity space of moving unit,...

Analysis Indicates Relationship between Food Packages and Food Quality Guarantee Period

As to most of the food, the deterioration is mainly caused by the growth of microorganism. The food processing procedures, including washing, sterilization, baking and frying, can greatly decrease the type and number of microorganisms in the food, or even kill them all. But, the microorganism residual rate can be affected by the factors such as raw material physical and chemical condition,...

Analysis on the Permeability of Non-Oxygen Conventional Gases

Oxygen and water vapor are not the only factors that cause the products become deteriorated which packed in various types of packages. With the popularization of MAP package and CAP package, the permeability of those gases, which were not usually neglected (including some inert gases), should be taken into consideration in package testing. Oxygen and water vapor permeability test have been...
