How to vulcanize?
The process of converting plastic rubber to elastic rubber is called vulcanization. It is to add a certain amount of vulcanizing agents such as sulfur, vulcanization accelerator, etc. to the semi-finished product in the rubber extruder. In the vulcanization tank of the rubber extruder, heating and keeping warm at a predetermined temperature make the linear molecules of the raw rubber cross-linked into a solid network structure through the formation of “sulfur bridges”, so that the plastic compound becomes highly plastic. Flexible vulcanizate. Because the cross-linking bond is mainly composed of sulfur, it is called “vulcanization”. With the rapid development of synthetic rubber, there are many types of vulcanizing agents in addition to sulfur, as well as organic polysulfides, peroxides, metal oxides, and so on. Therefore, any process that can transform the linear structure of plastic rubber into a three-dimensional network structure of elastic rubber is called vulcanization. Substances that can act as “crosslinks” in rubber materials are called “vulcanizers”. The vulcanized elastic rubber is called vulcanized rubber, also called soft rubber, commonly known as “rubber”. Vulcanization is the most important process in rubber processing. Various rubber products must be vulcanized by rubber extruder to obtain ideal performance. Unvulcanized rubber has no use-value in use. However, the degree of vulcanization is not enough, the vulcanization time is not enough to reach the best state, the over-sulfur vulcanization time is exceeded, and the performance is significantly reduced, all of which reduce the rubber performance. Therefore, rubber extruder must strictly control the curing time during the production process.
What are the preparations before using rubber extruder?
(1) Plastic for extrusion molding. The raw materials used in rubber extruder should meet the specified drying requirements and should be further dried if necessary. The raw materials are screened to remove lumps and mechanical impurities.
(2) Check whether the water, electricity, and gas systems in the rubber extruder are normal, to ensure that the water and gas paths are unblocked and leak-free, whether the electrical system is normal, the heating system, temperature control, and various instruments work reliably; Observe whether the rubber extruder is operating normally; Start the vacuum pump of the sizing table and observe whether it is working normally; Add oil to lubricate the lubrication parts of various equipment. If any malfunction is found, it should be eliminated in time.
(3) Install rubber extruder head and sizing sleeve. Select the specifications of the machine head according to the product variety and size, and install the machine head in order.
What are the reasons and solutions for the unstable current of the host?
1. Reasons for production:
(1) rubber extruder feeds unevenly.
(2) The main motor bearing is damaged or poorly lubricated.
2. Treatment method:
(1) Check rubber extruder and troubleshoot.
(2) Check whether the heaters of the rubber extruder work normally, and replace the heaters if necessary.
(3) Check the adjustment pad and pull out the screw to check if there is any interference in the screw.
Qingdao Huicai Machine Manufacture Co., Ltd developed a rubber extruder. If you also need a rubber extruder, then I think we are a company worthy of your choice, because we strictly control quality and price, and the price is extremely high.
