Water-based paint is most suitable for indoor wall experts to teach you to buy attention
According to the home air survey, 87% of home air contains volatile organic compounds such as formaldehyde, and it is mostly in boards, plywood and paint. However, there are many kinds of paints on the market. We ask experts to teach you to choose a paint that is harmless and has a good atmosphere.
First, the type of paint
Although the paint on the wall is commonly known as paint, it can be divided into oil paint and water-based paint. The oil paint itself and the pine perfume used for blending contain organic volatiles such as formaldehyde. Used outdoors, water-based paints contain low organic volatiles and are suitable for indoor use.
Second, purchase attention
1, see the instructions
Water-based paints or oil-based paints contain formaldehyde and organic volatiles (VOC). According to the current domestic certification, the green building materials mark can indicate that the VOC is low in volatilization, which is a safer choice.
2, sufficient lighting to choose flat light
The interior of the white wall can be selected as a flat water-based paint, and the wall will be too bright due to light reflection, otherwise the eyes will be easily fatigued.
3, test color under different light colors
The home is mostly yellow or white, the paint color will be different under different light colors. Generally, the yellow light makes the color darker and redder. Before buying the paint, you can test the color card under yellow and white light to confirm the brush at home. a feeling of.
4, increase the brightness of the eggshell light
The interior is dark lacquered or has a small space. The eggshell lacquer is optional. Because the constituent particles are refracted by light, the brightness of the room can be increased.
Optical Microscopy
In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.
