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.

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.

Because IXPE products are thin, such as the use of XPE/XLPE's horizontal and continuous foaming machine structure, it is prone to failures such as sticking or breaking during the foaming process. For this reason, our predecessors have specially developed a foaming machine structure that combines a horizontal furnace and a vertical furnace: the IXPE extruded mother sheet is preheated in the horizontal furnace section and enters the vertical furnace section when it is foamed. The IXPE extruded mother sheet is naturally It sags, and the blowing agent decomposes at high temperature, so that the IXPE extruded mother sheet expands naturally in the vertical foaming furnace, and a perfect IXPE foam product is obtained. The foaming furnace of this process is the IXPE vertical foaming furnace.

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.

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.

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, which was purchased recently, is about to complete factory production and enter the delivery stage.

IXPE floor mat is a silent mat. It is a foamed film made of high-pressure polyethylene (LDPE), cross-linked by electron irradiation, and foamed with an IXPE foaming machine. Ultra-fine foam provides cushioning and shock absorption. The composite aluminized film can play a role in moisture-proof. Installed under the floor, not only can absorb vibration and sound insulation, but also keep warm for floor heating. If special ingredients are added when making IXPE foam, IXPE foaming material with antibacterial, mildew, and flame retardant functions can also be made.

Qin Ding Company serves the XPE foam, IXPE foam and Crosslink foam industries, and has two XPE/IXPE foaming machine manufacturing bases and a foaming mat manufacturing plant. Qin Ding has advanced Crosslink Foam technology and craftsmanship, and has a professional PE Tech Foam team. The company's XPE/IXPE foaming machine factory produces more than ten XPE/IXPE foaming lines per year, and uses relatively large quantities of steel and copper materials, which are affected by the market price fluctuations this time. To this end, the company’s leaders made a decision: From June 1, 2021, according to the current market prices of raw materials, the price of XPE foaming machine is expected to increase by 20~30%, and the price of IXPE foaming machine is expected to increase by 15%~25%.
