The shell of the charging pile is shared6Plastic can be used in three parts: charging pile shell, charging pile plug, charging pile socket, charging gun shell, circuit breaker, contactor and power module shell.Due to the long-term use of new energy vehicle charging equipment outdoors, it is necessary to consider the influence of many factors such as high-voltage safety, frost resistance, ultraviolet resistance, hydrolysis resistance, flame retardant and so on. Therefore, different parts of the shell material has the corresponding material selection requirements, not only to meet the performance requirements, but also economic and safe.WeFor everyone to share the new energy vehicle charging pile modified plastic overall solution:
12. Raw material of charging pile shell:PC/ABS XL6600Fire rating
GRS,ROHS,REACHSuch as environmental certification and can be openedTC.
Flame retardantV-0/1.6mm,overBall pressure, high weather resistance, cold and hot cycle and low temperature impact, acid and alkali chemical corrosion resistance
It can meet the requirements of various colors.
As an external protection component of the charging pile, the charging pile shell not only needs to meet the protection requirements for possible collisions during transportation, installation and use, but also must be suitable for complex operating conditions. The materials used need to have certain mechanical strength and electrical Insulation and flame retardancy requirements, while having excellent weather resistance, low temperature impact performance, corrosion resistance and processing performance.
It is recommended to use flame retardant, weather resistant and low temperature resistant modified plastic materials suchPC/ABSalloy material, which combinesPCInABSThe excellent performance of both, on the one hand, providesABSThe impact resistance, heat resistance, rigidity of thin-walled products, etc., on the other hand, can improve melt fluidity, improve processability, electroplating and appearance. YujieRPC/ABSFrom the dismantling of electronic products, computer electrical housings, toys and other materials used after recycling. Through innovative physical modification methods, the physical properties of new materials produced by imported international brands and the world's major petrochemical plants are the same, and they can completely replace imported raw materials.
22. Material of charging gun shell:PC XL945Fire rating
GRS,ROHS,REACHSuch as environmental certification and can be openedTC.
Flame retardantV-0/2mmhigh dielectric strength, weather resistance, low temperature impact, highCTI
Can meet the needs of the preparation of various colors
In addition to flame retardant performance, electrical insulation performance and weather resistance, the shell and connection system of the charging gun should also have good rigidity and toughness to avoid damage caused by falling and vehicle rolling, while taking into account good appearance. Halogen-free flame retardant and weather resistance are recommended for materialsPCand its alloy materials.PC(Polycarbonate) is an amorphous, odorless, non-toxic, highly transparent colorless thermoplastic engineering plastic, colorless and transparent, heat resistant, impact resistant, with good mechanical properties, high refractive index, good processing performance, high strength and elasticity coefficient, low forming shrinkage, good dimensional stability, good weather resistance, harmless to human body and health and safety, YujieRPCFrom the use of buckets, plates, electronic products and other broken recycling. After innovative physical modification, throughGRS,ROHS,REACHSuch as environmental certification and can be openedTC.
3Raw materials of charging connector:PET,PA66
GRS,ROHS,REACHSuch as environmental certification and can be openedTC.
Flame retardantHB/2mmHigh dielectric strength, excellent mechanics
The charging connector, including the socket and plug, is directly connected to the wire. It needs excellent electrical insulation, flame retardant performance, and heat resistance. At the same time, in order to meet the long-term service life requirements of plugging and unplugging, the material needs excellent mechanical properties. Suggested selectionPET,PA66Series of modified plastic materials. Power module shell and internal circuit control system materials, it is recommended to choose good physical properties, high temperature resistance, size and color stability, laser marking effect of modified nylon material. Nylon (polyamidePA) The main characteristics of plastics are excellent mechanical properties, such as high strength, good rigidity, good wear resistance, self-lubricating, wide temperature range, good electrical insulation performance, arc resistance, good flame retardancy, self-interest, good oil resistance and chemical stability, easy processing, etc. The requirements of different functions can be met by modification methods such as reinforcement and filling. Nylon plastics are widely used in automobiles, machinery, electronic appliances, communication equipment, instrumentation, station building materials, etc. YujieRPA66Raw materials can be done100%PCRTraceability.
4Internal control system components raw materials:PAorPBT
The internal control system components mainly include power modules, contactors, circuit breakers, cooling fans, etc. Reference to commonly used power supply systems and low-voltage electrical industry material applications, can use halogen-free flame retardant enhancementPAorPBTMaterials. The cooling fan is recommended inITWidely used flame retardant reinforcement in the industryPBTorPPEMaterials.PBTis a thermoplastic polyester. Compared with other thermoplastic engineering plastics, non-reinforcedPBTIt has better processing performance and electrical performance.PBTLow glass transition temperature, mold temperature50C, can be quickly crystallized, the processing cycle is short. Polybutylene terephthalate(PBT)Widely used in electronics, electrical and automotive industries.PBTDue to high insulation and temperature resistance, it can be used as a TV flyback transformer, automobile distributor and ignition coil, office equipment shell and base, various automobile exterior parts, air conditioning fan, electric furnace base and office equipment shell.
4Material of cable assembly:TPE,TPU,PVC
Flame retardantHB/2mm
The cable used by the charging pile mainly includes the power line and the signal control line, and the structure, rated voltage, operating temperature, allowable bending radius and durability of the charging pile cable are specified in detail. Polymer materials are mainly used in the inner sheath and outer sheath of the cable, the inner sheath can use halogen-free flame retardant.TPE,TPU, the outer sheath can be usedPVC, halogen-free flame retardant elastomer, etc.TPEThe material is a composite thermoplastic elastomer, which can be recycled, can reduce a lot of costs, and is a product that is conducive to environmental protection.

New materials bring changes in mobile phones
The emergence and popularization of touch screens have gradually made us bid farewell to the years when we used physical keyboards to manipulate mobile phones. Today's trendy mobile phones cannot even find a physical keyboard on the main screen. The emergence of capacitive touch screens has even made mobile phones bid farewell to the standard stylus. We have begun to use one finger to click on two fingers to rotate and zoom to manipulate the screen. The influence of new materials on us is obvious. At this CES, several updated materials let us see the possibility of further changes in the way of interaction.
