Application of XPE IXPE foam material in air-conditioning insulation pipe
Air-conditioning cooling liquid copper pipes need to be insulated. The main materials of air-conditioning insulation pipes usually used are EPDM, NBR, EPE, XPE, IXPE and other rubber and plastic foam materials.
EPDM and NBR are foam rubbers with open-cell structure, high water absorption rate, and easy to age outdoors, but the material cost is low and it is widely used.
EPE is a foamed plastic tube that can be directly molded, but due to its open-cell structure, it also has the disadvantages of high water absorption and easy aging. Because it can be directly formed into a tube, the production cost is low, and the installation is convenient, so it is used more in areas with less developed economy.
XPE and IXPE are closed-cell foamed plastics, which are much higher than other materials in terms of thermal insulation and comprehensive performance. XPE foam and IXPE foam are cross-linked foam materials with high cross-linking degree, excellent weather resistance and corrosion resistance. Long service life outdoors. However, when a single XPE or IXPE foam material is used to make pipes, it is more difficult to manufacture because of the greater internal stress of the plastic. Because of the high cost, it is usually used in high-demand occasions.
In the actual production of XPE foam and IXPE foam air-conditioning insulation pipes, in order to improve the comprehensive performance of the air-conditioning insulation pipes, the material cost is also considered. Manufacturers generally use 10mm thick EPE extruded tube as the core tube, covered with 1.5mm XPE or IXPE cross-linked foam material, and in order to improve durability and aesthetics, it is outside the XPE foam or IXPE foam foam material. Then carry out laminating and embossing.
For applications with higher requirements (such as all-weather and outdoor use), multi-layer XPE foam or IXPE foam foam materials are also heat-bonded to form a tube, and aluminum foil or aluminum film is laminated on the surface.
At present, with the awareness of environmental protection and the improvement of quality in various places, more and more places use XPE foam and IXPE foam foam materials for air-conditioning insulation pipes.
XPE or IXPE foam material is a material with high technical requirements. It has high requirements on product formula, production process, machine equipment configuration and so on. Manufacturers need to customize different product formulas and production processes according to the needs of downstream users. Qin Ding has a large number of customers in this industry and has accumulated rich experience. It can provide different equipment according to the different markets targeted by customers, and can provide customers with a full range of materials, technical formulas, production processes, and secondary processing.
