What is wearing a heat insulation aluminum profile? What is pouring heat insulation aluminum profile?
Heat insulation aluminum section is to use glue strip to cut off the heat transfer of aluminum profile, popular point explanation, I'm not very professional.First, wear insulation:Extruded two aluminum sections, through the two bars to connect it to an aluminum profile, forming insulation profiles.Two 、 glue injection and heat insulation:An aluminum extrusion is extruded, and the aluminum material outside the rubber is cut off by pouring the heat insulation glue to form a heat insulation section.The price of the adhesive will be more expensive than the stripe.
Process a comparison, "wear type" VS "pouring" process comparison (1) production process strip insulation aluminum strip, generally separated teeth, rolling three steps, there are equipment manufacturers opened the teeth and wear on a piece of equipment to complete, known as the "two step". Gulleting: is a hard roll with gear device will aluminum part out of insulation to tooth wear. The aim is to increase the roughness of the profile by hobbing, thereby increasing the shear force of the composite profile. As the profile is divided into two parts, both inside and outside, according to the needs of production, gear equipment is generally two units. Wear: it is to wear the insulation strip to the profile, the inside and outside the two parts linked together, for the next step rolling preparation. Just one device. Rolling: the process can be divided into three steps: direction and pre clamping, main clamping and straightening (horizontal direction and vertical direction). It is the key to ensure the compactness and verticality of finished profiles. (2) the production process of "casting" is the surface treatment of aluminium and good linear motion through the driving system, the heat insulation slot of the aluminum profile after bottom pouring head pouring machine, liquid flow to the heat insulation material groove, after solidification after a period of time and then cut the bridge.
The strip process is made up of two heat insulation strips to connect the two inner and outer parts of the aluminum profile, thereby preventing the conduction of heat inside and outside the aluminum profile, and realizing the purpose of energy saving. According to incomplete statistical data, there are nearly 100 companies in China that adopt imported strip production equipment and domestic strip production equipment, and less than half of the total quantity is produced normally. Both the pouring process and the threading technology have good heat insulation performance, which are the development directions of the energy-saving aluminum alloy building materials. In this regard, the state has pointed out the necessity of developing the cold bridge with broken heat. And this year will be rolled out aluminum alloy insulation construction profiles national standards. The market for heat insulation and energy saving profiles will become clearer.
