Let's talk aboutinterior wall putty powderWhat are its properties?
Outsideinterior wall putty powderThe main purpose is to fill the gaps in the construction surface, correct the curvature deviation of the construction surface, and lay a good foundation for obtaining symmetrical and smooth car paint. The role of interior wall putty manufacturers is important in the following aspects:
Decorative function:
In painting projects, customers require the wall surface to be not only flat but also smooth and delicate, especially for some coating materials, which require a higher gloss on the wall surface. It is necessary to improve the gloss and try to enhance the characteristics of the putty rural base.
Eliminating turtle cracks:
The anti-self-cracking and anti-cracking properties of building surfaces, especially the outer wall tile layer, are core indicators of putty quality. Putty production companies often produce fine surface cracks due to cement aggregation, known as "turtle cracks." Turtle cracks often lead to coating powdering, peeling, and even cause wall seepage. Therefore, this is a key focus of putty technology research and development.
Blocking effect:
Flatness is a basic requirement for spraying paint, so filling ability is a fundamental element of putty. During construction, there are countless instances of unevenness, such as the unevenness of mixed mortar surfaces, unevenness of some wall surfaces, or the wave-like undulations of wide roofs under light, all of which damage the beauty and elegance of the building.
The characteristics of interior wall putty are flexibility, waterproofness, polishability, coating properties, and anti-cracking of the rural base.
1. Flexibility
Flexibility is the property of raw materials to deform under internal forces without permanent deformation.
2. Waterproofness
The waterproofness of interior wall putty reflects the bonding tensile strength after soaking or wetting. Since the putty is in direct contact with mixed mortar or lime powder plaster mortar on the rural base and often comes into contact under moderately humid conditions, it requires the putty to have excellent corrosion resistance.
3. Polishing
Interior wall putty is generally polished with sandpaper to achieve the surface gloss required for decoration design. The difficulty of polishing is generally referred to as "polishing performance," which is usually inversely proportional to the bonding tensile strength, strength, and surface smoothness of the putty. The polishing performance is tested by applying a putty film, drying it in a constant temperature and humidity device for 24 hours, adding 200g of fragments, and polishing 100 times with 300-grit water sandpaper, then observing the appearance of the putty film.
4. Adaptability
There are three construction methods for interior wall putty: brushing, rolling, and spraying. The coating properties require smooth construction without obstruction, and the putty has filling properties.
5. Anti-cracking of the rural base
The anti-cracking requirement of the rural base requires that the raw materials themselves have certain ductility or plasticity. When micro-cracks occur in the rural base, the raw materials undergo ductile plastic deformation under internal forces, preventing cracks from forming on the surface.
