Injection molding condition Injection pressure It is usually in 750~1250bar, depending on the design of materials and products. Injection speed High speed (for reinforced material should be slightly lower). Runner and gate: the location of the gate is very important because of the short solidification time of the PA66. The gate diameter of the gate should not be less than 0.5*t (here t is the thickness of the plastic part). Production method PA66 The first section Polyamide resin, the English name is polyamide, referred to as PA. It is commonly known as Niron (Nylon), which is contained in the repeating unit of the main chain of the macromolecule The general name of the polymer of the amide group. Among the five major engineering plastics, the highest yield, the most variety and the most widely used are the varieties. Main varieties of nylon Nylon 6 and nylon 66 dominant, nylon 6 and nylon 66 nylon, polyhexamethylene adipamide, nylon 66 It is more hard l2% than nylon 6, followed by nylon 11, nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, and nylons. Long 7, nylon 9, nylon 13, new varieties of nylon 6I, nylon 9T and special nylon MXD6 (barrier resin), nylon modified varieties There are many kinds, such as reinforced nylon, monomer casting nylon (MC nylon), reaction injection molding (RIM) nylon, aromatic nylon, transparent nylon, High impact (super toughened) nylon, electroplated nylon, conductive nylon, flame retardant nylon, nylon with other polymer blends and alloys, and so on, meet different characteristics. It is widely used as a substitute for metal, wood and other traditional materials. The characteristics and application of the second section First, characteristic As a large amount of engineering plastics, nylon is widely used in the fields of machinery, automobiles, electrical appliances, textile equipment, chemical equipment, aviation, metallurgy and so on. It has become an indispensable structural material in various industries. Its main features are as follows: 1. excellent mechanical properties. The mechanical strength of nylon is high and the toughness is good. 2. self moistening, good friction resistance. Nylon has a good self - moistening, small friction coefficient, so it has a long service life as a transmission component. 3. excellent heat resistance. The thermal deformation temperature of high crystalline nylon, such as nylon 46, is very high. It can be used for a long period at 150. PA66 passes through After glass fiber reinforced, the thermal deformation temperature is above 250 degrees centigrade. PBT 2. esterification is continuously fed at low temperature?or?normal reaction temperature, easy to control, safe and reliable. Design scale The single line capacity of industrial design is 3-40 tons per day, with an annual output of 1000 tons -15000 tons. Continuous synthesis Process description 1. 1-4 butanediol mixing and conveying system 2. slurry preparation system 3. esterification reaction system 4. process tower system 5. precondensation reaction system 6. prepolycondensation filtration system 7. terminal condensation reaction system 8. end polycondensation filtration system 9. slice cutting and packing system 10. catalyst preparation and continuous addition control system 11. filter cleaning system 12. THF recovery system 13. heat medium system 14. computer integrated control system Characteristic 1. low temperature, low mole ratio, mild reaction 2. reliable stay time 3. maintain reasonable material consumption at different reaction stages 4. low consumption, energy saving and economy 5. good melt rheological property
