It has the advantages of low water absorption, good oil resistance, low temperature resistance, easy processing and so on. brief introduction [Chinese name] nylon -11; polyomega aminoeleven [dissolve] insoluble in general solvents, only soluble in methylene phenol, etc. [use] a thermoplastic resin. It is used to make oil pipe, film, cable sheath and so on. [preparation or source] is obtained by condensation of Omega - aminoacid eleven acid. [Others] are resistant to ordinary acids, alkalis and oxidizing agents. Low water absorption, good dimensional stability, good wear resistance and oil resistance. The plasticized modification with N, N- two methyl p-toluene sulfonamide was plasticized PA11, and the mechanical properties of the system were studied. Because N, N- two methyl toluene sulfonamide and PA11 all contain -NH2, both of them have good compatibility. A small amount of plasticizer can greatly improve the impact strength of PA11, while the tensile strength is not greatly damaged, which effectively improves the comprehensive performance of PA11.。 ABS Main uses PC/ABS regenerator is an important engineering plastic alloy, which is widely used in automotive, electronic, electrical, office and communication equipment and other fields. Nowadays, in order to meet the special requirements of fire safety in the application field, especially in electronics and electrical products, the flame retardant technology of PC/ABS alloy has become a hot research topic. However, with the progress of science and technology, the requirements for the environmental friendliness of materials are becoming more and more high, and the traditional halogen flame retardancy is becoming more and more harmful. In engineering, ABS is widely used in engineering pipes. In the city, ABS pipes can generally be used in the bottom pipe of the project with high material requirements. 3D printing field Abs plastic is one of the main materials of 3D printing. It can be used as a consumable material for 3D printing. Its characteristics determine that ABS plastic has the characteristics of heat resistance, impact resistance, low temperature resistance, chemical resistance, excellent electrical performance and stable product size. At present, ABS plastic is the most stable material in the 3D printing material. [2] Preparation method Extrusion process Squeeze。 Plastic ABS produces pipes, sheets, sheets and profiles and other products. Pipes can be used for conveying pipes of various pipes, pipes, lubricants and fuel oil. Plates and sheets can be used for floors, furniture, tanks, filters, wall compartments, and thermoforming or vacuum molding. Screw length diameter ratio is usually relatively high, L/D is between 18~22, the compression ratio (2.5~3.0): 1, to use the gradient type fish mine head screw, barrel temperature respectively: hopper 150~160 C 180~190 C, the front of the barrel, the die temperature is 185~195 DEG C, mold temperature 180~200, the temperature blow molding can be controlled at 140~180 DEG C. Injection molding process Product and mould design LLDPE Thermal sealing The thermal sealing of LLDPE film is good, so long as the lowest sealing temperature is reached, it has good heat sealing strength, and the sealing ability of the seal is strong. Melting property The melting properties are determined by the relative molecular mass, the relative molecular mass distribution, the long branched chain and other factors. Similarly, the relationship between LLDPE and LDPE and shear rate: LLDPE Hu behavior is similar to HDPE with relatively narrow molecular weight distribution, and the melt viscosity is higher than that of LDPE. Therefore, extrusion load and heat consumption increase when extruding. The melting tension of LLDPE is lower than that of LDPE, and the relaxation time of the melting stress is short. It can be observed that the necking of the melt film extruded from the "T" type head is large, and the vertical extension of the hollow shape is large. Due to the short melting stress relaxation time, the residual stress in the injection molding products is small, so the shrinkage rate is small and the warpage is small. thermal property The melting point of polyethylene is proportional to the degree of crystallinity and grain size. Therefore, the melting point of LLDPE is 10-15 degrees higher than that of LDPE. Even though the same LLDPE, the more carbon number of monomer is, the higher melting point is. This rule is also suitable for VEKA softening point. The thermal sealing performance of the film is corresponding to the heat sealing temperature of the full melting. The LLDPE sealing temperature is 10-15 degrees higher than that of LDPE, and the melting point of LLDPE is narrower than that of LDPE, so the film has good thermal sealing performance.
