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.

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. And we can provide directional services.

From August 1st to 2nd, 2021, the IXPE gas heating foam machine signed by a large foreign enterprise company and Qin Ding Company was delivered. A total of 8 containers are shipped this time. The entire production line includes a discharger, a storage device, a tractor, a gas-heated horizontal foaming machine, a gas-heated vertical foaming machine, an exhaust gas recovery integrated heating unit, and a vacuum expansion unit. , Five-roller cooling unit, surface treatment unit, correction unit, trimming traction unit, winding unit and corresponding frame.

IXPE foam material has the following excellent physical properties: Flame retardant: The IXPE foaming products can reach FMVSS302 standard, UL standard, HB, V-2, V-1, V-0 (HB UL94 plastic flame retardant grade inspection method). Environmental protection: tested by SGS, the world's most authoritative organization, 100% of the IXPE foaming products have passed the EU ROSH environmental protection directive, free of peculiar smell and toxic substances. Heat insulation: IXPE foam products independent cell structure, no air circulation, thermal conductivity ≤0.04W/m∙k. Sound insulation: 100% airtight chamber, effectively reducing the sound intensity, excellent sound insulation, meeting STC-73, IIC-72 standards Waterproof: water absorption rate is lower than 0.02g/cm2 Aging resistance: After being modified by electron irradiation, IXPE foaming products have good weather resistance and chemical resistance, and the aging time is more than 15 years.

The molding methods of polyethylene foam include extrusion, injection, molding, orientation and other methods. Among them, the extrusion method is divided into direct extrusion foaming and cross-linking foaming after extrusion. After extrusion, cross-linked foaming can be divided into chemical cross-linked foaming, physical cross-linked foaming and mixed cross-linked foaming.

The full name of IXPE foam material is electron radiation cross-linked polyethylene foam material. It is based on LDPE (low-density high-pressure polyethylene), ADC foaming agent and color masterbatch as the main raw materials, with other auxiliary materials, after granulation and extrusion molding processes, the use of high-energy electron beams generated by industrial electron accelerators to extrude The formed mother film is irradiated to build a chain bridge between the molecules, and then foamed at a high temperature to form an independent closed-cell foam material. Finally, the material can be processed into the final foam product after punching, printing, thickening and other back-end processing procedures.

Recently, the gas-heated IXPE foaming machine purchased by a large Korean PVC plastic floor manufacturer from our company is about to complete the factory production stage and is expected to be shipped in early July.

After about 2 months of hard work, Qin Ding Company has made concerted efforts to complete a set of XPE foam production line that an Indian company ordered to our company. This batch of XPE foam production line cargo has been loaded into containers and entered the port on June 15. The ship will arrive at the port on June 22 and depart for the port of Mumbai, India on the 23rd. I wish this batch of goods can reach the port of Mumbai safely, and then our company will send professional engineers to install and debug.

The XPE/IXPE foaming machine division is one of the three divisions of Qin Ding Company, and it has 2 production bases. The main products are XPE foaming machine (Horizontal production line), IXPE foaming machine (Vertical production line), XPE/IXPE foam sheet extruder, XPS foam product line etc. We have advanced Crosslink Foam technology and craftsmanship and a professional PE Tech Foam team, which can provide a variety of advanced project solutions for customers to choose from.

Recently, a leading XPE product company located in Guangdong, China, in order to meet the rapidly growing business, the XPE foaming machine produced by our company recently purchased and completed and shipped on May 25. After arriving at the customer site, the installation engineers of our company worked day and night. After 15 consecutive days of intense work, this set of XPE foaming machine has completed the installation of the host.
