Broken bridge aluminum doors and windows there are three connection threading methods for transmission. It is integrated with pouring type, strip type and pouring roll pressure respectively. There are many production processes of strip profiles, complicated assembly of doors and windows, and accurate size requirements. The "glue" of plastic injection profiles requires high quality, and defects such as bubbles and blisters are easy to occur during production, and waste materials are found in the removal process. Pouring roller integrated use more raw materials, more complicated workmanship, more process than the first two kinds, the price is higher.
The principle of glue injection type is to design a heat insulation tank on doors and windows, and then inject insulation glue two-component polyurethane into the heat insulation tank. After insulation glue rapid reaction to generate solid polymer, the profile is insulation glue divided into two departments inside and outside, achieve the purpose of blocking heat exchange.
Strip-through heat insulation profiles are inserted into two sets of aluminum profiles, and then rolled into "Broken Bridge heat insulation". Two heat insulation strips connect the inside and outside parts of aluminum profiles, so as to prevent the conduction of heat inside and outside the aluminum profile and realize the purpose of energy saving.
Pouring and rolling one-piece is to combine the two, first made into a strip type, and then inject polyurethane insulation glue into the heat insulation tank. This performance is higher by forming a strip type on both sides and a polymer in the middle. The following figure shows the following figure.
In conclusion, there are more strips in the north and more glue injection in the South. Glue Injection heat insulation performance glue injection is good, the price is slightly higher. However, on the whole, these two forms of insulation broken bridge windows have the characteristics of light weight, high strength, good rigidity, large lighting area, good sealing waterproof and sound insulation performance, long service life, etc, it can clearly reduce the heat exchange inside and outside the building, and has obvious heat insulation, energy saving and good environmental protection effects.
