28.35mm PA66 GF25 Polyamide 66 thermal break insulating strip profile extrusion machine video
Application of polyamide strip:
1. Used for thermal break aluminum window, door, curtain and walls
2. Many customer use thermal break aluminum profile to do big air conditioner to keep heat of cold air, then make use of energy saving
Why use polyamide strip as thermal barrier function?
1. Because polyamide strip including Polyamide and glass fiber, Its Strength can reach requirement for aluminum profile window, door, curtain and walls.
2. Conductivity of polyamide strip is very low, prohibit hot air or cold air transferred from outside to inside, energy saving product.
"Wear a process" heat insulation material - the current domestic thermal insulation strip is polyamide 66+GF25 (Polyamide66, commonly known as nylon 66+25% glass fiber)
1 main materials PA66+GF
2 density (g/cm3) 1.3
3 tensile strength (N/mm2 = 110)
4 elastic modulus (N/mm2) 900
5 thermal conductivity (W/m2.k) 0.3
6 hot deformation temperature (℃) 250
The utility model mainly uses the special screw to make the polyamide nylon 66 and the glass fiber obtain good plasticization, and the extrusion die/tool extruded into a thermal insulating strip, which is widely applied to the doors, windows and curtain wall aluminum sheets through the different sections of the die.
PA66+GF pellets after drying machine into the hopper into the barrel, screw and pellets contact with the rotation of the screw forced to promote the spiral groove die direction. Because the screw barrel gap is small, the granular material is hot body under great pressure in the forward process; the temperature of the electric heating ring body is plasticizing nylon thermosol. Nylon plastic and plastic compression heating hot melt by extrusion molding, after traction, cutting or rolling process and become adiabatic adhesive tape products.
