Zirocnia Ceramics:
Zirconia polyethylene is an alkane inert polymer with good chemical stability. It is resistant to acid, alkali, and salt solutions at room temperature, but it is not resistant to strong oxidants such as fuming sulfuric acid, concentrated nitric acid and chromic acid. Polyethylene is insoluble in general solvents below 60°C, but it will swell or crack when it comes in contact with aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, etc. for a long time. When the temperature exceeds 60℃, it can be dissolved in a small amount of toluene, amyl acetate, trichloroethylene, turpentine, White Machinable Glass Ceramic Parts mineral oil and paraffin; the temperature is above 100℃, it can be dissolved in tetralin. As the polyethylene molecule contains a small amount of double bonds and ether bonds, sun and rain will cause aging, and antioxidants and light stabilizers need to be added to improve it. Because LDPE and HDPE have good fluidity, low processing temperature, moderate viscosity, and low decomposition temperature, they will not decompose at a high temperature of 300°C in an inert gas, so they are plastics with good processing properties. However, the viscosity of LLDPE is slightly higher, and the motor power needs to be increased by 20% to 30%; melt fracture is prone to occur, and the gap between the die and the processing aid needs to be increased; the processing temperature is slightly higher, up to 200-215°C. Polyethylene has low water absorption and does not require drying before processing.
Polyethylene melt is a non-Newtonian fluid, and its viscosity fluctuates slightly with temperature, while the increase in shear rate decreases quickly and shows a linear relationship, of which LLDPE decreases the slowest.
Polyethylene products are easy to crystallize during the cooling process, so pay attention to the mold temperature during the processing. In order to control the crystallinity of the product, make it have different properties. The molding shrinkage rate of polyethylene is large, which must be considered when designing the mold.
