Product Description: Cold-resistant PC, or cold-resistant polycarbonate, is a polymer material with excellent low-temperature performance. PC itself is renowned for its outstanding mechanical properties, optical performance, and dimensional stability, while cold-resistant PC further expands its application potential in low-temperature environments.In low-temperature environments, ordinary materials often become brittle and experience significant performance degradation, but cold-resistant PC can maintain good toughness and strength. Generally, it can operate normally at temperatures as low as -40 degrees Celsius or even lower, with its impact resistance almost unaffected. This is due to its unique molecular structure, where the forces between molecular chains allow it to remain tightly bonded even at low temperatures, effectively resisting external impacts.The applications of cold-resistant PC are extremely wide. In the aerospace industry, aircraft face extremely cold environments during high-altitude flights. Cold-resistant PC can be used to manufacture aircraft components, such as cabin interiors and dashboard casings, ensuring safety and reliability in low-temperature conditions. In outdoor electronic equipment, such as surveillance camera casings and communication base station equipment housings used in extremely cold regions, cold-resistant PC protects internal precision electronic components from low-temperature damage, ensuring normal operation. In automotive manufacturing, some external accessories, such as rearview mirror casings and headlight covers, are made from cold-resistant PC, enabling them to withstand the impact of snow and ice and the test of low temperatures during cold winters, maintaining the vehicle's appearance and functionality.With continuous technological advancements, the performance of cold-resistant PC is still being optimized. In the future, it is expected to play an important role in more fields with stringent low-temperature performance requirements, providing strong support for the development of related industries. more>

Product Description: Low-Temperature Water Chiller UnitUnit OverviewA low-temperature water chiller unit designed for low-temperature conditions, composed of two or more independent refrigeration cycles, with a refrigeration temperature typically ranging from -5°C to -50°C. Due to the diversity of products, some production processes and equipment cannot meet the actual working condition requirements with normal-temperature water cooling. Only low-temperature circulating water can fulfill the practical production process requirements, necessitating the use of low-temperature water chiller units.Refrigeration PrincipleThe compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which enters the condenser. Part of the heat from the refrigerant in the condenser is expelled by external cooling water or cooling fans. The refrigerant releases heat and liquefies into a high-temperature, high-pressure liquid, which then flows through a dryer filter for drying and filtration. It then passes through an expansion valve for throttling (a rapid cooling process) and pressure reduction, liquefying into a low-temperature, low-pressure liquid that enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water, oil) in the evaporator. During the heat absorption process, the refrigerant temperature remains constant while its volume changes. After absorbing heat, the low-pressure liquid refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and enters the condenser, thus completing the entire refrigeration cycle.Two-Stage Refrigeration Cycle SystemThe two-stage refrigeration cycle is developed based on the single-stage refrigeration cycle, with the compression process divided into two stages. The refrigerant vapor from the evaporator enters the low-pressure stage cylinder and is compressed to an intermediate pressure. After intermediate cooling, it enters the high-pressure stage cylinder and is compressed to the condensation pressure before entering the condenser. Generally, when the evaporation temperature is between -25°C and -50°C, a two-stage compressor should be used for refrigeration. The refrigeration system consists of an evaporator, two-stage compressor, oil separator, condenser, intermediate cooler, ammonia receiver, ammonia liquid separator, throttle valve, and other auxiliary equipment, all connected by pipes to form a closed system. The intermediate cooler uses a small amount of liquid refrigerant to vaporize and absorb heat at intermediate pressure, cooling the superheated vapor discharged from the low-pressure stage, reducing the suction temperature of the high-pressure stage, and also cooling the high-pressure liquid refrigerant.Main Components of the Unit:Compressor: The core component of the entire refrigeration system and the power source for the refrigerant.Evaporator: A heat exchange component that relies on the evaporation of liquid refrigerant to absorb heat from the cooled medium.Condenser: Plays a role in the refrigeration process by dissipating the heat output by the compressor and allowing the refrigerant to condense.Thermal Expansion Valve: Commonly known as a throttle valve in the refrigeration system.Liquid Receiver: Installed at the evaporator and compressor suction pipe to prevent liquid refrigerant from entering the compressor and causing liquid hammer, serving as a protective component.Refrigerant: The refrigeration system uses R22, R404a, R407c, R134a, and R410a as refrigerants.To enhance the stability of the water chiller unit during use, the EU quality system management certification has been actively implemented in the production process, and product quality control is meticulously managed in supplier selection.Features1. Brand-name compressors are selected, with built-in protection, low noise, energy savings, and durability.2. The electrical components use brand-name products such as "Schneider," "Siemens," and "LG" to ensure stable machine operation and long service life. 3.

A fully stainless steel thick-walled tank-type evaporator is used, with built-in automatic water replenishment and other devices, low-water-level automatic protection, and an open design for easy and quick cleaning and maintenance.7. The unit has eight protection functions: power phase sequence protection, leakage protection, compressor overload protection, coil overheating protection, high and low pressure protection, water shortage protection, chilled water flow protection, and anti-freeze protection.8. The condenser of the industrial water chiller unit is a sleeve type with internal threaded copper tubes, designed reasonably for excellent heat exchange performance. The air-cooled unit's cooling fins are composed of finned rows of copper tubes, manufactured using secondary flanging fin mechanical expansion tube technology and advanced heat exchanger production lines to ensure product energy efficiency.7. Electrostatic spray-coated shell with European design, aesthetically pleasing and elegant. The exterior panels are designed for quick disassembly and assembly, facilitating use and maintenance.Unit PerformanceThe low-temperature water chiller unit uses multiple compressors in parallel, each with its own chilled water circuit.

During the heat absorption process, the refrigerant temperature remains constant while its volume changes. After absorbing heat, the low-pressure hydraulic refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and enters the condenser, thereby completing the entire refrigeration cycle.Two-Stage Refrigeration Cycle SystemThe two-stage refrigeration cycle is developed based on the single-stage refrigeration cycle, with the compression process divided into two stages. Refrigerant vapor from the evaporator enters the low-pressure stage cylinder and is compressed to an intermediate pressure. After intermediate cooling, it enters the high-pressure stage cylinder and is compressed to the condensation pressure before entering the condenser. Generally, when the evaporation temperature is between -25°C and -50°C, a two-stage compressor should be used for refrigeration. The refrigeration system consists of an evaporator, two-stage compressor, oil separator, condenser, intermediate cooler, ammonia receiver, ammonia liquid separator, throttle valve, and other auxiliary equipment, all connected by pipes to form a closed system. Among these, the intermediate cooler uses a small amount of liquid refrigerant to vaporize and absorb heat at intermediate pressure, cooling the superheated vapor discharged from the low-pressure stage, reducing the suction temperature of the high-pressure stage, and also cooling the high-pressure liquid refrigerant.Main Components of the Unit:Compressor: The core component of the entire refrigeration system and the power source of the refrigerant.Evaporator: A heat exchange component that relies on the evaporation of liquid refrigerant to absorb heat from the cooled medium.Condenser: Plays a role in the refrigeration process by dissipating the heat output by the compressor and allowing the refrigerant to condense.Thermal Expansion Valve: Commonly known as a throttle valve in the refrigeration system.Liquid Receiver: Installed at the evaporator and compressor suction pipe to prevent liquid refrigerant from entering the compressor and causing liquid hammer, serving as a protective component.Refrigerant: R22, R404a, R407c, R134a, and R410a are used as refrigerants in the refrigeration system.To enhance the stability of the water-cooled unit during use, the EU quality management system certification has been actively implemented in the production process. Quality control over product quality is rigorously managed in the selection of suppliers.Features1. Compressors are selected from reputable brands, featuring built-in protection, low noise, energy efficiency, and durability.2.

Full stainless steel thick-walled tank evaporator, equipped with automatic water replenishment and other devices, low-water-level automatic protection, and an open design for easy and quick cleaning and maintenance.7. Eight major protection functions: power phase sequence protection, leakage protection, compressor overload protection, coil overheating protection, high and low pressure protection, water shortage protection, chilled water flow protection, and anti-freeze protection.8. For industrial water-cooled units, the condenser is a sleeve type with internal threaded copper tubes, designed for optimal heat exchange efficiency. For air-cooled units, the cooling radiator consists of fins and rows of copper tubes, manufactured using secondary flanging fin mechanical expansion tube technology and advanced heat exchanger production lines to ensure product energy efficiency.9. Electrostatic spray-coated shell, European-style design, aesthetically pleasing and elegant. The outer panel adopts a quick-disassembly form for easy use and maintenance.Unit PerformanceThe low-temperature water-cooled unit uses multiple compressors in parallel, each with its own chilled water circuit. All compressors are controlled by a unified microcomputer control system, starting and stopping sequentially. Additionally, Ninewells brand units are entirely made with imported original parts, resulting in extremely low single-unit failure rates.

Product Description: What is Stainless Iron 430F: 430F stainless steel is a grade of steel with enhanced machinability added to 430 steel. It is used for automatic lathes, bolts, nuts, etc. 430LX adds Ti or Nb to 430 steel, reduces carbon content, and improves processing and welding performance. It is used for hot water tanks, hot water supply systems, sanitary ware, household durable goods, bicycle freewheels, etc.Why 430F Struggles with Salt Spray: 430F belongs to the stainless iron series, which is inherently more prone to rusting compared to the 300 series stainless steel materials. Additionally, the F-grade material contains sulfur and has not undergone heat treatment processing, significantly reducing its rust resistance. So, how can we prevent it from rusting? The solution is to use Jiayimei brand stainless iron passivation solution for passivation treatment. This raises the question: what is stainless iron passivation? How should the stainless iron passivation solution be operated? Below, we will introduce the advantages of stainless iron passivation solution and its operational process.430F Passing 48h Salt Spray Test: Upon receiving the customer's requirement for 430F to pass a 48-hour salt spray test, Jiayimei's technical R&D team focused on developing a solution specifically for this material. Ultimately, they helped the customer resolve this issue. JYM-1000-2 is primarily used for various stainless iron F-grade materials. After treatment, the workpiece's dimensions and color remain unchanged, and rust resistance can be improved by 6 to 10 times.Standard Process Flow:Degreasing — Rinsing — Passivation — Rinsing — Stabilization — Rinsing — Pure Water Soak — Drying and PackagingThe above process can be adjusted as needed.Precautions:Containers for passivation can generally use plastic baskets, plastic tanks, or stainless steel tanks.Passivation temperature is 70°C for 30 minutes; stabilization temperature is 65°C for 15 minutes.The passivation solution does not contain harmful substances and is environmentally friendly.It passes the nationally standardized blue dot test, with no blue dot appearing within 35 seconds.Operators must wear labor protection gear to avoid contact between the solution and skin.For wastewater treatment, neutralize with alkaline lime water or CH2OH until the pH reaches 7 before discharge, ensuring no environmental impact.If you wish to learn more about passivation and rust prevention, please call Jiayimei Company for consultation and discussion. All staff at Jiayimei look forward to your call. more>
