How to do roof waterproofing

In home decoration, in addition to the bathroom and kitchen need to be waterproof, the roof is also the most need to be waterproof. The roof of the building is often exposed to the outside, often exposed to the sun and the wind, it is inevitable that there will be water leakage and other phenomena. So how do waterproof roof, the roof waterproof material What? Let's take a look at the following content!

How to do roof waterproofing

1. Ensure the quality of waterproof materials

First of all, we must choose the roof waterproof material. The waterproof material must be selected with quality assurance, and it must also be certified by the designated quality inspection department to ensure that the quality meets national standards.

2. Pay attention to the roof drainage slope

Before construction, pay attention to the roof drainage slope, which is about 2% to 3%. If the slope is less than 2%, the material should be used to find the slope. If the slope is greater than 3%, the structure should be used to find the slope.

3. Do all the preparatory work

Secondly, we must carefully check the roof construction drawings and master the detailed structure in the construction drawings to avoid problems after construction and affect the quality of the project.

4. Prepare the materials

Roof waterproofing generally uses coiled material waterproof material, and waterproof material should be installed after masonry and pipeline installation are completed.

5. Pay attention to the seam of the flat layer

Seam treatment is the most critical part of the waterproofing project. Failure to make the joints well will cause roof leakage in the future. Therefore, when doing waterproofing, the leveling layer must be provided with lattice joints and filled with sealing materials to ensure that there will be no water leakage after construction.

Introduction of roof waterproof material

1. HG203 waterproof sealing coating

HG203 waterproof sealing coating is a kind of commonly used in roof waterproofing. It introduces advanced high-tech technology from the United States. And made of imported raw materials, it is a very environmentally friendly waterproof coating, non-toxic, odorless and flame retardant.

2. Modified asphalt waterproof

Modified asphalt waterproof material can also be used for roof waterproofing. It is characterized by high temperature resistance, and it can be used in a temperature range of -25 to + 100 ° C. It has high elasticity and fatigue resistance, so it plays a big role in roof waterproofing.

3. Elastic cement

Elastic cement is also called polymer cement. It uses a polymer emulsion composed of acrylate as the main material. It is characterized by good film forming, impermeability and water resistance. It can be applied even on a wet base. And the waterproof effect is also very good.

Xiaobian Summary: The above is about how to make the roof waterproof, waterproof material content roof, I do not know whether we understand it! Roof waterproofing is very important, so in order to ensure the safety of family living, everyone must take a closer look. Moreover, it is best to ask professional people to operate the roof construction to avoid inadequate experience affecting the waterproof effect.

Roof waterproof

There are two principal neodymium magnet manufacturing methods:
ï‚·Classical powder metallurgy or sintered magnet process
ï‚·Rapid solidification or bonded magnet process

Bonded NdFeB Magnet is made by evenly mixing neodymium iron boron powder with resin, plastics and low melting point metal and so oncaking agents, then made the boron permanent magnet of compound neodymium iron by methods such as compressing, pushing or injecting shaping. The products take shape once, do not need processing again and can be made into various complicated forms derectly. All directions of the Bonded Ndfeb Magnet are magnetic, and can be processed into compression moulds and injetion moulds.

Bonded Ndfeb Magnets are prepared by melt spinning a thin ribbon of the NdFeB alloy. The ribbon contains randomly oriented Nd2Fe14B nano-scale grains. This ribbon is then pulverized into particles, mixed with a polymer, and either compression- or injection-molded into bonded magnets. Bonded magnets offer less flux intensity than sintered magnets, but can be net-shape formed into intricately shaped parts, as is typical with Halbach arrays or arcs, trapezoids and other shapes and assemblies (e.g. Pot Magnets, Separator Grids, etc.). There are approximately  5,500 tons of Neo bonded magnets produced each year. In addition, it is possible to hot-press the melt spun nanocrystalline particles into fully dense isotropic magnets, and then upset-forge or back-extrude these into high-energy anisotropic magnets.

Bonded magnets can be made from either hard ferrite materials or rare earth magnetic powder. They are manufactured using both injection molding and compression bonding techniques which are fully automated and are particularly suitable for high volume production.
Bonded neo powder is incorporated into numerous end market applications that utilize bonded neo magnets. These products are primarily motors and sensors used in a range of products, including computer and office equipment (e.g., hard disk drives and optical disk drive motors and fax, copier and printer stepper motors), consumer electronics (e.g., personal video recorders and mp3 music players), automotive and industrial applications (e.g., instrument panel motors, seat motors andair bag sensors) and home ventilation systems (e.g., ceiling fans).

Application of Bonded Neodymium magnets:
•Magnetic separators
•Microphone assemblies
•Servo motors
•DC motors (automotive starters) and other motors
•Meters
•Odometer
•Sensors
