Control measures of the insulate double glazing
Control measures of the insulate double glazing
(1) Strictly control the insulate double glazing production environment temperature
The production environment mainly affects the attachment capacity and the remaining adsorption capacity.
(2) Reduce the diffusion of water through the polymer
It mainly depends on choosing sealant with low permeability coefficient to determine a reasonable sealing thickness and reduce the temperature difference between the inside and outside of the insulating glass (that is, control the production within a certain temperature range without making the temperature range too large).
(3) Reduce insulate double glazing production process time
Minimize the time that the desiccant is in contact with the atmosphere, reduce the loss of adsorption capacity and make the desiccant have a higher adsorption capacity.
(4) Choose the right aluminum profile for the insulate double glazing
The air conduction gap of the pores should be small to reduce the water absorption rate of the molecular sieve during operation.
(5) Choose a suitable desiccant laminated insulated glass
It is necessary to choose a desiccant with a high adsorption rate and a long lasting.
It is believed that the quality of insulating glass will be obviously controlled through the control of various links such as material selection, processing, and environment.
Production process
1 The heated laminated insulated glass should adopt multiple sets of pressing rollers and gradually press to the required thickness. Each set of pressing rollers should be parallel to each other to ensure uniform thickness of the pressed glass.
2 The temperature of the rubber strip at the exit of the press should be controlled at 40-55℃.
3 The sealing of the laminated insulated glass with composite rubber strip adopts a three-step procedure, namely pressing, turning and pinching, to complete the final
sealing operation of the insulating glass.
①Pressing: squeeze the outer rubber strip along the vertical direction of the edge to the other strip until the two rubber strips are completely fused together;
②Turn: Smooth the excess glue along the space layer in the middle of the hollow glass and laminated insulated glass, so that there is no excess glue on the outside;
③Pinch: Pinch two pieces of laminated insulated glass inward to eliminate the gap caused by the separation of glass to the outside caused by pressing and turning.
Pay attention to the problem about laminated insulated glass
①The temperature of the strip leaving the hot press;
②The sealing temperature, thickness, flatness and displacement of the rubber strip;
③The integrity of the sealing surface of the rubber strip;
④ Sealing tightness.
Identification method of the tempered insulated glass
1. Fill inert gas argon and krypton
According to experts in the design and construction of energy-saving residential buildings, as far as a tempered insulated glass window is concerned, the heat loss in the house is mainly through the conduction of the window frame, tempered insulated glass radiation, and convection between the window pages and the door frame. Therefore, "hollow glass" is applied. Born. In fact, "hollow glass" is not "empty". According to technical requirements, the distance between two layers of tempered insulated glass is generally 8mm. Tests have shown that if the 8mm gap is completely vacuumed, atmospheric pressure will crush the glass. Therefore, qualified insulating glass. The interlayer, that is, the 8mm thick spacing space, must be filled with inert gases argon and krypton. After filling, the test shows its K value (heat transfer coefficient limit value), which can be reduced by 5% compared with the same period in the vacuum state, which means better insulation performance.
2. Confused double safety insulated glass on the market
In other words, if the insulating glass you buy back is really "empty" in the interlayer, it will undoubtedly show that its heat preservation or cold insulation performance is at best double-layer glass, and the effect of heat preservation and energy saving must be poor. Scientific testing has proved that, Qualified insulating glass can reduce the heat transfer coefficient limit value of general window glass from 3.5 to 2.8, and the decrease in heat transfer performance can make the heat in the house not easy to lose. The counterfeit insulating glass on the market mostly simply fixes two pieces of safety insulated glass together, and its thermal insulation performance is undoubtedly poor.
3. Aluminum strip with holes between the safety insulated glass
"Double-layer glass" with inferior heat insulation performance often causes fog and blooms in the interlayer due to the entry of air and water vapor, and even mold spots. Therefore, some companies often use aluminum strips with holes between the two pieces of glass. The "processing" method of putting granular desiccant in the pores of the aluminum strip actually only serves as a temporary cover for the ears, and does not improve any heat insulation performance of the double-layer glass. After a long period of time, the desiccant will fail. Expose the stuffing.
One of the tricks to "verify the body" is to see if there is any ice between the glass in winter and see if there is moisture in spring and summer. Of course, most of the aluminum strips embedded in it are fake vacuum. The quality of the window frame is also a sign, and the insulating glass is generally made of plastic steel rather than aluminum alloy.
