It is not easy to produce a polyvinyl acetal enameled flat wire that meets both standard requirements and customer requirements. It is influenced by factors such as raw material quality, process parameters, production facilities and environment. Therefore, the quality characteristics of different polyvinyl acetal enameled flat wires are different. But they all have four main properties: mechanical properties, chemical properties, electrical properties and thermal properties.
Why is temperature important in the production of polyvinyl acetal enameled flat wire?
What is the scope of application of polyvinyl acetal enameled flat wire?
What is the production status of polyvinyl acetal enameled flat wire?
The distribution of oven temperature has a great relationship to polyvinyl acetal enameled flat wire. The distribution of furnace temperature has two requirements: longitudinal temperature and transverse temperature. The longitudinal temperature requirements are curvilinear, i.e. from low to high and then from high to low. The transverse temperature requires a straight line. The uniformity of the cross temperature depends on factors such as heating, heat retention and hot air convection of the equipment. The enamel furnace must meet the requirements of the packaging process
a) Accurate temperature control, +5 "C;
b) The furnace temperature curve can be adjusted and the maximum temperature in the curing zone reaches 550°C;
c) The lateral temperature difference does not exceed 5°C. In a furnace, there are generally three temperatures: heat source temperature, air temperature and wire temperature.
It is common to say that the furnace temperature is measured by a thermocouple arranged in the air, and the temperature is generally close to the temperature of the gas in the furnace.
Polyvinyl acetal enameled flat wire is the main raw material for electric motors, electrical appliances and household appliances. Especially in recent years, the electricity industry has achieved sustainable and rapid growth, and the rapid development of household appliances has created a wider application area for coated wires. What is coming are higher demands on coated wire. Therefore, the adaptation of the product structure of enameled flat wires is unavoidable, and the appropriate raw materials (copper, lacquer), enamel processes, process equipment and testing methods also urgently need to be developed and researched.
What is the production status of polyvinyl acetal enameled flat wire?
Polyvinyl acetal enameled flat wire is one of the earliest varieties in the world. It was launched in the 1930s by Germany and the United States. The Soviet Union is also developing rapidly. There are two types of polyvinyl acetal and polyvinyl acetal. The study was successful in the 1960s. Although the coated wire has low temperature resistance (105 °C, 120 °C), it is widely used in oil transformers due to its excellent hydrolysis resistance at high temperatures. In small quantities, polyvinyl acetal lacquered wires are mainly used for the production of Dremel conductors, which are used in large transformers.
Nantong Baiwei Electric Co. Ltd is located in the well-known port city of Nantong, which is called "North Shanghai". With experienced R&D capability, first-class production equipment, strong manufacturing capacity, Baiwei has been one of the large scale and high efficiency electrical equipment raw material manufacturing bases in China.
