The hot melt, a tool that is widely used in industrial manufacturing, construction and daily life. It he heaves solid plastic or rubber to a certain temperature through electrical thermal components, so that it is melted and used for bonding, sealing or filling.
The hot melt, a tool that is widely used in industrial manufacturing, construction and daily life. It he heaves solid plastic or rubber to a certain temperature through electrical thermal components, so that it is melted and used for bonding, sealing or filling.
The working principle of the hot melting device is based on the thermoplastic characteristics of the material, that is, some materials such as polyolefin plastic will change from solid state to a flow state when heating to a specific temperature, and it can be restored to solid state after cooling.This process is reversible, so it can be repeated multiple times.The hot melting glue rod is a commonly used supporting material for hot melt. When it is heated, it can quickly wet the surface of the bonding surface, cooling and solidifying to form a firm bonding.
The working principle of the hot melting device is based on the law of Jiao Er. When the current passes through the resistance wire in the heat meltr, the heat will generate heat. These heats are used to heat the gas (usually air) that heating flows over the resistance wire, which generates hundreds of hundreds of degrees Celsius.High temperature hot air.This high -temperature hot air can quickly heat the surface of the object, so that the plastic material can reach the melting point, thereby achieving welding of two plastic parts.In addition, hot meltrs can also be used to unravel and freeze pipelines, pipes, heat shrinking pipes, and removing the old paint layer.
The use of hot meltrs is very wide.In the packaging industry, it can be used for sealing, blocking, labeling, etc.; in the automotive industry, it is used for bonding, interior assembly and sound insulation materials for body components;Insulation and encapsulation.In addition, hot meltrs can be seen in the fields of furniture manufacturing, carpet laying, craft production and other fields.
The improvement of intelligence and automation makes the operation of hot melts easier and more accurate.For example, some high -end thermal melts are equipped with a temperature control system, which can automatically adjust the heating temperature according to the melting characteristics of different materials; some use image recognition technology to accurately apply hot melt materials to the predetermined location.
Environmental protection is also an important trend in the development of hot melt.In the future, the development of hot melt will also be deeply integrated with technologies such as the Internet of Things and big data.By collecting and analyzing a large amount of data, the manufacturer can monitor and optimize the performance of the hot melt, thereby further improving its work efficiency and reliability.
