Liyuan profile
Liyuan profile selection of the most advanced formula, high-quality PVC, imports of titanium dioxide and additives is the most advanced, through scientific processing and formulation, the performance reached the national standard.
1, the appearance of good quality, green environmental protection; color is clear white, beautiful appearance, high dimensional accuracy, profile unit length, quality stability.
2, product strength: narrowing the gap window profile steel lining and wall, greatly improve the product strength enhanced window, window and bear load Liyuan wind resistance ability.
3, fire resistance is good: non flammable, has excellent flame retardant performance, safe and reliable.
4, reasonable structure with multi cavity structure, enhanced steel lining cavity, drainage cavity and insulation cavity independent. To ensure that the insulation sealing doors and windows, but also avoid the steel rust.
5, light and heat stability is good: through the simulation aging test, each index is higher than the national standard.
6: good mechanical properties, flexibility, impact and tension Liyuan section and bending is also higher than the national standard.
7, corrosion resistance: Liyuan profile selection of unique formula, has good corrosion resistance.
Liyuan profile assembly structure
1, Liyuan profiles using multi cavity structure, drainage cavity, isolation enhanced cavity, heat preservation, ensure the tightness and enhance the corrosion resistance of steel, improve the service life of steel doors and windows.
Fastening screws,2 profile Liyuan hardware accessories, at least by fixing and reinforcing two layer wall, increase the reliability of the use of hardware.
European installation slot3, Liyuan bar with oriented hardware, for all production in accordance with the European standard hardware installation, ensure the use function of profile.
4, Liyuan increases the bearing body profile wall thickness, lost inner rib is unnecessary, non bearing body wall thickness is reduced, the profile meter weight decreased, greatly improving the outturn rate profile.
5, connecting profiles of a wide variety, supporting good, according to the strength of the wind pressure requirements or user preferences.
The6 and the drainage trough are processed by the method of internal and external positions, which can prevent cold air and dust from entering. Even when the wind pressure is large, the water can be discharged smoothly.
7, casement, window frame, fan inside and outside two special structures, special material sealing strip sealing, increased doors and windows watertight and airtight.
The8 and push and pull frames are provided with aluminium slide rails, and standard aluminium slides can be installed to make the window sash open more conveniently.
The adoption of9 and glass gasket facilitates the installation of glass, and also facilitates the adjustment of the amount of drainage and the amount of sagging of doors and windows.
10, Liyuan glass bead profile through the change of different types, respectively, can be installed in different thickness of single-layer glass, hollow glass.
Rubber11, Liyuan profile and after installation, the position on the same plane, beautiful appearance, and improves the lighting performance of windows and doors.
12, Liyuan all series of doors and windows, through the combination of special section, glass bead is always in the indoor side, easy to install and replace the glass, while increasing the use of safety.
13, through the replacement of hardware (different prices and structures), you can lock doors and windows from different locations, to facilitate the choice of users at different levels.
The upper and lower connecting parts of the two window sash of the14 sash window adopt a special bridge structure to seal; the sliding sash window and the two plane joint part adopt a special double channel sealing structure.
Liyuan plastic doors and windows assembly technology
No. 1, door and window selection,
carefully review the engineering drawings, in accordance with the requirements of the drawing style determines the type and quantity of required window, factors combined with the local wind pressure value, hole size, floor height and environmental conditions, determine the selection and the thickness of the stiffener type window.
two, door and window design,
in accordance with the selection of cutting rules, optimized design, including selection of glass, hardware, steel lining, rubber strip, wool and other ancillary fittings, of material design, made of material work plan.
three, profile cutting, milling water holes, keyhole
1, the main profile blanking is commonly used double headed sawing materials, the material left at each end of the 3mm to do welding margin, blanking tolerances should be controlled within 1mm, angle tolerance control within 0.5 degrees.
2, frame sections to milling drainage holes, fan profiles are generally milling holes and air pressure balance hole. It is required that the drain hole be 35mm in diameter and 30mm in length. The drain hole shall not be installed on the cavity with reinforced steel, nor shall it be penetrated through the chamber of the reinforced steel.
3, if you want to install the driver and the lock, to lock hole milling.
Assembly offour and reinforced steel
when the door and window components are larger than the specified length or need to assemble the hardware, the inner cavity of the door and window must be reinforced. The assembly of reinforced steel is pre inserted and fixed at the site where the welding is not affected. The cross section and T type steel shall be inserted at the beginning of the weld after the melting of the profile, and shall be fixed after welding. Reinforced steel is to strengthen the steel of PVC profile through fasteners, and the fasteners for each reinforcement shall not be less than 3, and the spacing shall be no more than 300mm, the distance from the steel end shall be no more than 100mm.
five, welding
welding should pay attention to the welding temperature of 240-270 degrees (according to the cross-section of profiles can be adjusted properly), the feed pressure 0.3-0.35Mpa, clamping pressure 0.4-0.6Mpa, melting time 20-30 seconds, cooling time 25-30 seconds.
six, clean corners,
1, clean corner, corner cleaning and mechanical cleaning
