Boron nitride insulation protection tube is milky white, with a true density of 2.27g/cm2, a Mohs hardness of 2, a high melting point (sublimation at 3000℃), and a service temperature of up to 2800℃ in an inert atmosphere. Its thermal conductivity is similar to that of stainless steel, at 25w/(m·k). The linear expansion coefficient is (2.0~6.5)x10-℃, with excellent thermal shock resistance, and can survive hundreds of hot and cold cycles from 1000℃ to 20℃ without damage.

Boron nitride products have good chemical stability and poor oxidation resistance, but can resist the erosion of acids, alkalis, molten metals and glass, and do not react with most molten metals such as copper, stainless steel, iron, tin, zinc, lead, etc.

 

 

Boron nitride insulation protection tube can be used as a crucible for melting and evaporating metals, a boat, a pipe for conveying liquid metals, a separation ring for continuous steel casting, a rocket nozzle, a high-temperature thermocouple protection sleeve, etc. Special products such as boron nitride fiber can be used as high-temperature fluid filters, radiation protection clothing, high-temperature furnace linings and thermal insulation materials.

Boron nitride film covered on a certain substrate can make it have heat resistance, insulation, corrosion resistance and other properties.

 

 

Boron nitride insulation protection tube can be processed by hot pressing, and the product can be finely processed with a turning accuracy of up to 0.01mm.

Suppliers can process various specifications of boron nitride products and provide boron nitride product blanks according to customer needs, with leading technology and excellent quality.

 

 

 

Product packaging is in accordance with the "Technical Specifications" or industry standards;

 

The packaging of the product is in line with the characteristics and performance of the product itself, including sufficient to prevent the product from moisture, rain, rust, corrosion, and shock, etc., and can accept multiple handling, loading and unloading, and transportation;

 

 

The production process of Boron nitride insulation protection tube includes key steps such as raw material selection, boron nitride powder preparation, molding, sintering treatment, post-processing and testing. Each step requires strict control of process parameters and operating conditions to ensure the quality and performance of the final product. With the advancement of science and technology and the continuous optimization of technology, the production process of boron nitride ceramics will continue to be improved and perfected, providing better material support for the development of various industries.
