Food machinery materials can be used
Considering the cost and health point of use of nonmetallic materials, other materials can be used instead of stainless steel, now suitable material is polypropylene (pp.polypropylene) which is a polymer material (- CH3, CH - N) is a crystalline plastics, its mechanical properties such as hardness, elastic modulus, the degree of Qiang Gang is better than the other a non-toxic plastic polyethylene, it also has excellent heat resistance, in the absence of external force, heated to 150 DEG C is commonly used in plastic deformation, only can withstand high temperatures, materials. Compared with stainless steel, it is superior in corrosion resistance and cost, but not in stress and surface hardness. In many parts of the food machinery can be used instead of stainless steel. In addition, in contact with food parts can also consider the use of ceramics and other materials.
In addition, in the high temperature environment, stainless steel and stainless steel materials, but also consider the content of lead and nickel. In this way, in the selection of stainless steel, should pay attention to the characteristics of its various brands.
Selection of materials used in food machinery:1, due to the surface of the metal is corroded, and then contact with food, it constitutes a pollution of food, therefore, in the design of food machinery, food contact with metal materials are used to Srainless.steel.
