Eva foaming reactorThe Eva foaming reactor was independently developed by Yan Zheng Instrument. Its flexible shaft magnetic couple driver combined high-performance flexible shaft materials with advanced magnetic couple technology. It had the characteristics of high torquing (110Ncm-748Ncm), long life, light and convenient, and was suitable for various high-viscous synthesis reactions. It uses the integrated control of the touch screen and the control panel, which is simple, convenient, and intuitive. The operation interface is clear, and the mechanical and cumbersome problems of the traditional button control are solved.
Its design parameters were as follows:
- Heat power: 500 - 4000W (different volume heating power).
- Design temperature: 300 ° C, service temperature: 50 - 250 ° C, temperature control accuracy: +/-1 ° C (without strong heat release and heat absorption).
- Design pressure: 150bar, burst pressure: 125bar, service pressure: 100bar (special instructions should be given when using negative pressure, and a negative pressure gauge should be installed and a negative pressure sensor should be replaced).
- Stirring power: 80 - 200W, stirring moment: 0.47 - 2Mm, stirring speed: 150 - 1000r/min.
The control system included:
- [Operation interface: 7-inch true color touch screen with a touch sensor. The display module can be customized by the user. The module can be turned on and off. There are multi-level menu and multi-window management settings.]
- "Control module: intelligent pid temperature control, support self-tuning, dual temperature control mode (main control kettle temperature, auxiliary control heating furnace temperature), temperature control accuracy of +/-1 ° C.
- Stirring module: Pulse width adjustment, up to 1000r/min, speed precision 0 - 5r/min.
- [Timer module: Dual timer mode (insulation timer and start timer).]
- Pressure module: The pressure sensor is imported from the United Kingdom. The accuracy is as high as 0.25%. It is made of 316L material and has a digital pressure display. It has an over pressure alarm and can customize the upper limit pressure.
- Lifting module: Independent mechanical button, can automatically separate the kettle body and kettle cover.
- Remote communication: remote control function, equipped with MODUS Rtu communication module.

What causes foaming at the mouth?There were two main reasons for foaming at the mouth: organic phosphorus poisoning and epilepsy. The organic phosphorus poisoning would suppress the sympathetic nerves, causing the pupils to constrict, the trachea to constrict, and excessive saliva secretion. When breathing, one would drool too much, as if they were foaming at the mouth. During a seizure, normal swallowing function is inhibited, and secretions cannot be discharged downward. At the same time, the secretion of glands is exuberant, resulting in an increase in secretions in the oral cavity and respiratory tract. In addition, the airflow in the lungs during the seizure increased, which could easily lead to foaming at the mouth. To determine the cause of foaming at the mouth, one needed to observe the patient's pupil size, breathing, and consciousness. Foaming at the mouth caused by poisoning needed to be differentiated from the symptoms of epilepsy.
Eva injection foaming molding machineThe Eva injection foaming machine was a kind of equipment used to produce Eva foam products. According to the reference materials, EVA foaming has two principles: physical foaming and chemical foaming. In terms of equipment, there was an Eva shoe sole recycling pellet machine, an Eva foam recycling pellet machine, an XPE foam recycling pellet machine, and other related equipment. The production line integrated mixing, conveying, feeding, squeezing, and water ring cutting and cooling. It could realize automatic continuous operation, high production efficiency, and good plastification and mixing effect. There were also curing presses such as the 63T Silica Forming Vulcanizer that could be used for Eva foaming. In terms of the secondary foaming molding machine for Eva, there were related equipment designed to facilitate the removal of the mold. Through specific structural design, such as the setting of the expansion cylinder, expansion rod, injection molding plate, spring, etc., it was convenient to remove the mold after the molding and improve the efficiency of the mold removal. The structure and process control of these equipment together serve the process of EVA injection foaming to produce lightweight, cushion, sound-absorbing and other functions of Eva foam products.
