The drying time should not exceed 10 hours. It is generally possible to judge whether drying is sufficient by air extrusion. The proportion of recycled materials can reach 20%. In some cases, of the recycled materials can be used, and the actual weight depends on the quality requirements of the products. Recycled materials cannot be mixed with different color at the same time, otherwise it will seriously damage the product properties. Selection of injection molding machine PC plastic products due to cost and other aspects, using modified materials, especially electrical products, but also increase the fire performance, in flame retardant PC and other plastic alloy products molding, injection molding machine for the plasticizing system requirements are mixed, good corrosion resistance, the conventional plasticizing screw to do, at the time of purchase, must be stated in advance. Design of mold and gate Common mold temperature is 80-100 degrees, plus glass fiber is 100-130 degrees, small products can be needle shaped gate, gate depth should have 70% of the thickest part, and other gates have ring and rectangle. The bigger the gate, the better, to reduce the defects that the plastic is overly cut. The depth of the exhaust hole should be less than 0.03-0.06mm, and the flow path is as short and round as possible. The deviation of the die is usually about 30 '-1. Melt Temperature The processing temperature can be determined by the method of air injection. The general processing temperature of PC plastics is 270-320 C, and some modified?or?low molecular weight PC plastic materials are 230-270 C. Injection speed More rapid injection speed molding, such as an electrical switchgear. It is common for slow - rapid prototyping. Back pressure The back pressure around 10bar can be reduced properly in the absence of air lines and coloring. Detained time When the time is too long at high temperature, the material will be reduced and put CO2 into yellow. Do not use LDPE, POM, ABS?or?PA tube cleaning machine. Use PS to clean up. Matters needing attention Some modified PC plastic raw materials, because the number of recycling too much (molecular weight reduction)?or?a variety of ingredients mixed uneven, easy to produce dark brown liquid bubble. [1] Performance and use physical characteristics PC is a kind of amorphous engineering material. It has excellent impact strength, thermal stability, gloss, inhibition of bacterial characteristics, flame retardancy and pollution resistance. The gap of PC's otched Izod impact stregth is very high, and the contraction rate is very low, generally 0.1%~0.2%. chemical properties PC has very good mechanical properties, but the flow characteristics are poor, so the injection process of this material is difficult. The final expectation of the product should be based on the quality of the PC material. If the plastic parts require high impact resistance, low flow rate PC material is used, otherwise, high flow rate PC material can be used, so that the injection process can be optimized. PC plastic material is a new type of thermoplastic, with a transparent degree of 90%, which is known as a transparent metal. It is rigid and resilient, with high impact strength, high dimensional stability and wide range of service temperature, good electrical insulation, heat resistance and innocuity. It can be injected and extruded. PC plastics have excellent thermal properties and can be used for a long time between -100 C and -130 C, and the embrittlement temperature is below -100 C. Although polycarbonate has the characteristics of resistance to cracking and drug resistance, high temperature is easy to hydrolyze, poor compatibility with other resins, and poor lubricity, it can be modified by adding other resins?or?inorganic fillers, resulting in excellent performance. PEEK PEEK fiber (including monofilament) industrial filter cloth, industrial brush and other products. In the field of composite materials, the charm of PEEK fiber lies in its thermoplastic and high temperature resistance. In addition to heat resistance in industrial filter and industrial brushes, its charm is still in its chemical resistance and wear resistance. 7. The field of medical analysis instruments Because of the high pressure sterilization of PEEK can be repeated, in the medical device can be used in the manufacture of endoscope parts, dental scalers etc.. In addition, because of the high strength and low solubility of PEEK, it has been used in the analysis of liquid chromatography column, tube, accessories and so on. Moreover, because of the good compatibility of PEEK with the human body, the artificial bone material has succeeded in replacing the traditional titanium metal.

When the temperature reaches 70 C, it is easy to deform and can not be loaded with liquor and oil at high temperature. The performance of PET (1) the general performance PET resin is milk white translucent?or?colorless transparent body, the relative density is 1.38, and the transmittance rate is 90%. PET is a medium barrier material, and the transmission coefficient of O2 is 50 to 90cm3 mm/ (m2. D MPa). The transmission coefficient of CO2 is 180cm3 mm/ (M2 d). The water absorption of PET is 0.6%, and the water absorbability is larger. (2) the tensile strength of PET film with mechanical properties is very high, comparable to aluminum foil, 9 times of that of HDPE film, and 3 times that of PC and PA films. Enhanced PET has small creep resistance, excellent fatigue resistance (better than enhanced PC and PA), good wear resistance and good friction resistance. The mechanical properties of PET are less affected by temperature. (3) the thermal properties of pure PET plastics are not very high, but they are greatly improved after enhanced treatment. The mechanical properties at 180 C are better than those of PF laminates, which is a good heat resistant variety of reinforced thermoplastic engineering plastics. The heat resistance of PET is good, the embrittlement temperature is - 70 C, and still has a certain toughness at - 30. PET is not easy to burn, the flame is yellow, and it drops. (4) although electrical performance PET is a polar polymer, it has excellent electrical insulation and can still be kept well at high frequency. PET has poor corona resistance and can not be used for high voltage insulation; the electrical insulation is affected by temperature and humidity, and is greatly influenced by humidity. (5) environmental performance PET contains ester bonds, which can not withstand water, acid, and alkali under the condition of high temperature and water vapor. PET is stable for organic solvents such as acetone, benzene, toluene, three chloroethane, carbon tetrachloride and oil. It also has high resistance to some oxidants, such as hydrogen peroxide, sodium hypochlorite and potassium dichromate. PET has good weatherability and can be used for a long time.
