Due to the influence of various natural conditions such as climate and environment, water leakage will occur when using Beijing color steel plate for a long time. At this time, it is necessary to carry out waterproof renovation in time. Generally speaking,
in order to prevent the water leakage of color steel tile and affect its normal use, it needs to use the corresponding waterproof materials, which waterproof materials will be used in the renovation of color steel tile?
Composition of special waterproof system of color steel tile metal roof:
1. Color steel tile reinforced polyester cloth.
2. Metal roof special waterproof system primer.
3. Metal roof special waterproof system surface coating.
waterproof layer forms the connecting elastic membrane of the joint, which is particularly convenient for the construction of the special-shaped parts with complex structure. It is based on self crosslinking pure acrylic emulsion, which is made up of
cooperative modifiers, functional auxiliaries and fillers. This kind of information is harmless, non-toxic and non combustible, which is a green and environmental protection commodity, of which 99% pure acrylic products are good. It has good elongation
and tensile strength, pure acrylic acid aging resistance is particularly good, the service life of the waterproof layer of Beijing color steel plate is also very long, and roll coating, construction is convenient, scratch coating can be constructed. The
color steel tile acrylic waterproof coating is a kind of environmental friendly, one component elastic waterproof coating.
The SBS waterproof roll or self-adhesive waterproof roll is used to treat the joints. Because the temperature of the color
steel tile steel roof in summer will reach more than 70 degrees, the asphalt in the roll has been in the melting state. After many times of melting and solidification, the roll is very easy to aging away from the metal roof panel, so the service life
is also short, usually about half a year to two years. Nowadays, there are many companies that make color steel tile metal roof waterproof, and their treatment methods are as follows (JS cement, silicone weather resistant adhesive, polyurethane, etc.)
they can solve the problem of metal roof water leakage in a short period of time, but their service life is not long. According to the combination of materials used, the short service life is only a few months, and the long service life is only 3-4 years.
