Paint, also known as oil paint, is a decorative material often used in homes or other buildings. The paint had a very pungent odor, and the homes decorated with it were generally ventilated for a long time before they could be used or used. However, with the progress of society, there has been a more environmentally friendly water-based paint on the market. What is the waterborne paint ? What is the difference between it and the oil paint? Let Xiaobian answer it for you.
1, what is the water-based paint
Water-based paint is what paint? In a broad sense, water-based paints are resin-based paints that use water as a dispersant, and mainly include: water-soluble water-based paints, water-diluted water-based paints, and water-dispersible water-based paints. But for the specific definition, water-based paint is a paint that uses water as a diluent and does not contain organic solvents.
2, the difference between water-based paint and oil paint
a. Environmental Protection Index
Because water-based paints use water as a dispersant, water-based paints do not contain toxic and harmful substances such as formaldehyde and toluene, which means that the waterborne paint has a low VOC content. Therefore, the water-based paint has a high environmental protection index and will not only cause environmental pollution. , And it will not cause harm to the human body, it is green and safe.
On the other hand, oil-based paints are based on organic solvents such as Senna, which are formulated with benzene, acetic acid, and ethyl esters, indicating that they contain harmful substances such as toluene, and they do not have the characteristics of environmental protection. It will cause harm to human health.
b. Smell
Water-based paints do not contain harmful substances such as formaldehyde and toluene, so no irritating odor is produced during the brushing process. Because of this property, water-based paints can be immediately admitted after brushing.
Oily paints are not good. Because of the use of benzene, acetic acid and other substances, toxic gases can evaporate into the air when they are painted. This can make people feel pungent; You should stay at least one to two months later.
c. Service life
The water-based paint adopts the advanced film-forming technology. The hardness of the paint film is high, the surface layer is firm and firm, and the abrasion resistance is strong. The flexibility is high, and it will not turn white due to collision. In addition, it is also safe and non-flammable and has a long service life.
The paint film of oily paint is poor in hardness, and it needs to be brushed many times to achieve the effect of water paint; and the paint film is easy to white after collision, and the wear resistance is poor, and it is also easy to self-ignite, not easy to store, the service life is relatively It's shorter.
Xiaobian conclusion: The above is what the water-based paint is what paint and water-based paint and oil paint what is the difference between the introduction, after reading the small series of finishing content, I believe we know what kind of paint for home decoration. Therefore, for the sake of family's health, it is recommended that everyone choose a water-based paint with a higher environmental factor.
Thin wall ball bearings are simple in structure and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
Characteristics
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
