How to make the system window profile impermeable?

Aluminum profile doors windows are equivalent to the eyes of a house, the seepage of doors windows only affects the appearance of the house, but also affects its service life. So how to make aluminum profile doors windows impermeable? Specifically, it should be analyzed several aspects such as aluminum profiles, sealants, glass.

First, let's analyze the reasons for water leakage in aluminum profile doors windows. Firstly, the selection of aluminum profile materials:

1. The surface treatment of aluminum profiles is unqualified, the oxide film is too thin too thick, which makes the surface coating unable to bond well, the sealant cannot bond well.

2. The main part of the aluminum beam is close to the quality of the column, the strength does meet the standard. The thickness of some parts is less than 3mm. Due to the influence of standard bearing capacity, the wall cannot withstand deformation, aluminum doors windows can also move, leading to leakage.

3. Defects such as selecting high-precision aluminum profiles for main components such as columns, substandard aluminum products, bending deformation, etc., prevent doors windows reaching horizontal vertical levels, seriously affecting the overall size of aluminum profiles.

Sealant:

1. The sealant is qualified is suitable for sealing materials of joints. Ordinary sealant is suitable for ordinary sealant, with lower cost, but cannot withstand long-term sunlight exposure, which can cause rapid aging cracking of the sealant.

Even if weather resistant silicone is used, the gel has expired the sealant that is too long cannot withstand the sealing effect. Whether it is cracked foamed, it will cause leakage of aluminum profile doors windows.

3. If the compatibility experiment of silicone material is done in advance, if silicone material is incompatible with aluminum profiles glass, chemical reactions may occur it cannot adhere well, which can also affect the sealing effect.

The importance of glass:

If there is no prior budget for the load-bearing capacity of glass, glass with insufficient load-bearing capacity will be able to withstand wind rain burst.

2. There is also no prior budget for the thermal stress of the glass. If the area of the glass is too large, its thermal stress should be greater than the allowable thermal stress, otherwise it will also cause thermal fracture of the glass damage to aluminum profile doors windows.

3. The size tolerance of glass is too large, how much space should be left on both sides, whether it has reached the specified size. If the glass size is small, it cannot reach the depth of embedding, the adhesive seam is wide enough, making it easy for the glass to crack on all four sides; If the size of the glass is too large, it will be deeply embedded easily expand when encountering high temperatures, then be crushed by aluminum profiles burst.

4. The edges corners of the glass are well ground, uneven edges of the glass can cause stress concentration, leading to cracks posing safety hazards to users.

The construction aspect is also important:

1. In the operation of the installation workers, the aluminum alloy frame is installed as required, the diagonal, horizontal, vertical lines of the doors windows are properly controlled, which can change the physical properties of the wall.

2. The installation of sealant does comply with regulations, the proportion of required sealant length total width is sound, resulting in lax sealing.

3. In the absence of control over the construction conditions of the sealant, the sealant should be applied at a certain temperature humidity. If it rains, do apply, especially in outdoor working environments high temperature excessive humidity can seriously affect the quality of the sealant must be applied by Heaven.

4. The selected sealant size is appropriate, expired sealant will quickly fall off due to improper size, expired sealant will quickly age, which will have a waterproof effect.

5. There is no use of elastic cushion blocks between the glass the components, which will increase the stress between the components the glass, causing aluminum profile doors windows to compress the glass the bottom, causing the glass to crack.

It is also closely related to users of aluminum profile doors windows:

1. Users do have a detailed understanding of the use of aluminum profiles for doors windows. Improper use of doors windows can also damage them, causing water loss penetration.

2. Failure to clean doors windows may also cause damage to the doors windows of aluminum profiles.

3. Some users make unauthorized modifications to doors windows for convenience, the modifications themselves are professional after all. Some of the modifications have been properly waterproof, resulting in water seepage in aluminum profile doors windows.

There is still a problem, we must find a solution to the problem, especially what can prevent water seepage in aluminum doors windows?

Firstly, we need to understand the conditions for water seepage in aluminum profile doors windows: ① there are gaps; ② There is water; ③ There is a pressure difference. Solution: ① Minimize gaps as much as possible; ② Try to find ways to block rainwater; ③ Reduce the pressure difference. The specific methods are as follows:

1. The selection of sealant materials should be cautious, weather resistant silicone materials must be selected, it is also important to check whether the materials have expired; Attention should also be paid to the selection of glass materials, high-quality glass should be selected. The edges corners should be polished the size error should exceed the standard.

2. Leave a small hole on the aluminum door window so that the water entering the gap will flow out, the water between the aluminum glass will be removed.

3. The sealing bonding construction conditions should be well controlled, rainwater should be used during outdoor construction. The indoor temperature should be kept below 27 ℃, the relative humidity should be maintained above 50%. Before adding sealant, dust debris in the gaps should be removed, the surface should be maintained after injection, maintenance work should be done well.

4. For the convenience of future maintenance, concealed inspection should be carried out after the installation of the aluminum profile frame. Layered seepage inspection should be carried out during the installation of doors windows. After the installation of doors windows, engineering acceptance should be carried out to ensure the quality of the profile.
