Waterproof leak-blocking principle and twenty-eight little common sense

Waterproof leak for everyone to know, but most people on its operating principle is difficult to explain clearly, so this article for you to introduce waterproof leak principle and small common sense, to help you in daily life encountered in the house leakage of small problems.
The principle of waterproofing and leaking is to use the inherent chemical and porous properties of concrete itself, with water as the carrier, with the help of water penetration and chemical reaction in concrete, along or against the direction of water pressure, in the concrete micro-holes and capillary pipe transmission, filling, catalytic concrete incomplete hydration of the composition of the chemical action, the formation of insoluble cranberry crystal and concrete combined as a whole, so that any direction of water and other liquids blocked.
When the structure does not have water, the active components of Jingwei will remain stationary, but when in contact with the water again, the above chemical action and closure process will be repeated, and will be more deep into the concrete, so as to achieve permanent waterproof, moisture-proof, chemical corrosion resistance purposes, but also to protect the steel bar, enhance the strength of the concrete structure, can self-repair less than 0.41mm cracks
China
. And harmless to human body, easy to build and so on, widely used in industrial and civil buildings underground structures, subways, bridges, road surfaces, drinking water plants, sewage treatment plants, power stations, water conservancy and other projects.
We understand the principle of waterproof leak, next we will look at waterproof leak 28 common common sense, although the content is more streamlined, but we can refer to the reference, the specific content is as follows:
01
pieces of rigid waterproof layer
to seep into the waterproof cement mortar for the bottom waterproof layer, the middle layer of clay brick and other fast materials, and then with waterproof cement mortar irrigation and waterproof layer.
02
backing material
adds depth to control the inlay of the sealing material, prevents bonding of the sealing material and the bottom of the seam, and sets the deformable material between the bottom of the seam and the sealing material.
03
water storage roof
a certain height of water on the roof waterproof layer, playing a role in insulation roofing.
04
plant roofs
cover the roof waterproof layer with soil or lay loose materials such as sawdust and zircon, and plant plants to provide insulation.
05
upside-down roof
set the water-repugnent insulation on the roof on the waterproof layer.
06
waterproof layer durability
refers to the roof waterproof layer can meet the normal use requirements of the period.
07
Asphalt waterproof coil
with raw paper, fiber fabric, fiber felt and other tire materials soaked in asphalt, surface sprinkled powder, granular or flaky material to make a curly sheet waterproof material waterproof leakage is so simple!
08
High polymer modified asphalt waterproof coil
to synthesize polymer modified asphalt as a coating layer, fiber fabric or fiber felt for the tire body, powder, granular, flaky or thin film material for the cladding material to make a curly sheet waterproof material.
09
cold asphalt gluing material
s made from petroleum asphalt, fillers, solvents, etc.
10
Synthetic polymer waterproof coil
to synthetic rubber, synthetic resin or their mixture as the base material, add the appropriate amount of chemical additives and fillers, etc. , processed into a curly sheet waterproof material, or the above material and synthetic fibers and other composite into two or more layers of curly sheet waterproof material.
11
seeding method
using waterproof coils with self-adhesive, no hot construction, no need to apply glue materials, and bonding construction methods.
12
waterproof to fill leakage hot air welding method
the use of hot air welding gun waterproof coil he, bonding construction method.
13
asphalt-based waterproof coatings
milk-based or solvent-based waterproof coatings made from asphalt as a base.
14
high polymer modified asphalt waterproof coating
with asphalt as the base material, modified with synthetic polymer, with the resulting milk-based or solvent-based waterproof coating.
15
Fill leak synthetic polymer waterproof coating
to synthetic rubber or synthetic resin as the main film-forming substance, with a single or multi-part waterproof coating.
16
budget treatment agent
in order to enhance the bonding force between the waterproof material and the grass, before the waterproof layer construction, pre-coated paint on the grass.
17
seams
in order to reduce cracks, look for flat, rigid waterproof layer, rigid protective layer on the roof of the pre-retained seams. Rigid protective layers are only made into V-shaped grooves on the surface, called surface-splitting seams.
18
waterproof filling and leakage paving method
when paving waterproof coils, the coil and the grass only within a certain width around the bonding, the rest of the non-bonding construction method.
19
tire body enhancement material
refers to the chemical fiber non-woven fabric, fiberglass mesh cloth and other materials used in the coating waterproof layer.
20
cold adhesive method (cold construction
using adhesive or cold ma king fat for coil and grass, coil and coil bonding, without the need for heating construction method.
21
overhead insulated roofs
thin products made of sintered clay or concrete, covering the waterproof layer of the roof and setting up a certain height of space, using air flow to speed up heat dissipation, play a role in insulation roofing.
22
-point adhesion method
to lay waterproof coils, coils or punched coils and the grass using point bonding construction methods. Each square meter bonding not less than 5 points, each point area of 101mm × 101mm.
23
alsized asphalt sealing material
using asphalt as a base material, modified with the appropriate amount of synthetic polymer polymer, add fillers and other chemical additives made of paste sealing material.
24
synthetic polymer sealing material
is mainly synthetic polymer material, with the right amount of chemical additives, fillers and colorants, processed through a specific production process of paste sealing material.
25
seam displacement
in the roof system, due to temperature, external forces caused by the seam gap changes.
26
stretch-compression cycle
reflects the sealing material's ability to maintain the seal after periodically pulling and pressing the cycle due to seam displacement caused by temperature changes.
27
(full stick method)
to spread waterproof material, the coil and the grass using all bonding construction methods.
28
method
the waterproof coil, the coil and the grass using the construction method of strip bonding. Each coil and the base bonding surface is not less than two, each width is not less than 151mm.
