Installation method of heat-insulating shutter door
1. Draw a line at the opening of the installed door frame to mark the corresponding position and indicate the size. It should be noted that the height inside the door frame is higher than that of the door leaf. The thermal insulation shutter door installed outside the door can usually improve the K value of the door by at least 45%, and ensure that the distance between the shutter door plate and the door frame is ≥40mm during installation.
2. In order to fix the door frame of the thermal shutter door, the fixing plate at the lower part of the door frame should be removed first, and grooves should be reserved on the ground on both sides of the hole in advance, and then correction should be made. After passing the test, fix the wooden wedge, and weld the iron foot of the door frame with the embedded iron plate.
3. When installing the main body of the door leaf, it is necessary to ensure that the thermal shutter door and the wall are integrated and sealed, and then paint the hole and the wall. After painting, the gap of the door should be even and smooth, and the hot rolling door should be free and light, and there should be no over-tightening, over-loosening and rebound.
Installation points of thermal insulation rolling shutter door
1. In order to ensure the tightness of the hot rolling shutter door when it is closed, the seat strip must be sealed with the contact surface, and usually an elastic sealing profile can be set at its lower end.
2. There must be a sealing device, an elastic rubber strip or a silicified top on the guide rail, and the width of the guide rail with the sealing device must adapt to the thickness of the blade.
3. In order to reduce the heat loss when the shutter door is opened, the shutter door plate in the closed state must be pressed on the outside of the shutter door box, and sealing strips should be installed at the corresponding gaps when necessary.
4. In order to meet the requirements of reducing the heat loss of components, it is necessary to add insulation materials with a thickness greater than 20mm to the opposite surface of the dark louver box, and the gaps can be sealed with sealing strips.
Thermal insulation shutter door equipment
1. feeding system: simple manual feeding frame is adopted, with heavy load, which can run with the main engine and synchronize with the main engine. Simple double-roll feeding and leveling treatment can make the strip enter the forming roller table smoothly and accurately.
2. Forming system: the roller is made of bearing steel. After cutting, lathe shaping, quenching, finishing and chromium plating, the control quantity is strictly controlled in each process to ensure the accuracy and service life of the roller. There are 39 rollers on the whole line.
3. Foaming system: injecting polyurethane material for foaming, reshaping and heating.
4. Punching system: Punching is controlled by the control cabinet program, then it is cut into a certain length by the flying saw as required and sent out by the discharging rack.
