Good dimming glass light transmittance over how much

There will be slight leakage is the main reason in, this is a typical Ming frame glass curtain wall node. In practical engineering. Aluminum briquetting is commonly made of 50 mm in length, place a piece of every 350 mm, thickness of aluminum decorative lines generally to 1. 5 mm, cloud line marker, aluminum decorative lines between the eco-friendly tube and glue, due to some position without aluminum under the pressure and strip, of sealant should be unable to effectively control the quality, for a year or two, sealant easy to produce the problem such as craze, make curtain wall leaking, breathe freely! Four, unit glass curtain wall leaking

by adjacent unit commonly strip lap to realize each other, (1) dust tight line. An seal line designed for dust barrier. Have the effect of blocking dust and cover with water. Southern region can not design the sealing line. By a small amount of leakage on the surface of the wall can be crossed the line, 2 watertight line. The unit curtain wall important line of defense. Enter the unit curtain wall, such as cavity pressure, by reasonable structural design, into the isobaric cavity will be organized to discharge water, without the ability to continue to enter indoor, reach the purpose of block water sometimes in order to improve the watertight performance of curtain wall, may also be the multichannel watertight lines at the same time.

because of the constant pressure between the lines to watertight and airtight cavity and outdoor is basically same ( Sometimes placed on connecting holes to prevent dust sponge) Therefore watertight line can't stop the air permeability, and is an important line of the unit curtain wall. To prevent air infiltration by the last line of defense Air line. In order to using the rain act principle for waterproof curtain wall surface. Design make the isobaric cavity pressure Pc is equal to or close to outdoor Po is watertight basic wind pressure is equal on both sides of the line, to eliminate or reduce the effect of wind pressure, make water is not passed or rarely by dust tight line and watertight line into the pressure chamber.

gap and action also inevitable, airtight line on both sides. To achieve purpose is to make the water leakage tube less than air line, to eliminate leakage, water factor is the three elements by dust tight line and line of the watertight of little or no water, drainage combined with reasonable organization, there is no water spray into the air line, air tight line gap around without water, leakage will happen, so that the wind-load * to the insert part has a good waterproof ability.

it is the key to the success of wind-load * waterproof, waterproof wind-load * is the weak link of four units & # 39; + ' Word seam. The more successful solutions include cross sliding type and & # 39; + ' Word cross seal structure, etc. , here no longer mentioned. It is necessary to switch the light eco-friendly tube technology to do more detailed solution. Strict in quality of customers. Have & # 39; Stuffed dumpling made of cotton & quot; A sealant to solve inserted core cannot cover the gap, in the practical engineering of & # 39; Transverse & # 39; The unit curtain wall.
