In today's society, with the development of science and technology, some industrial products have also been developed. However, the development of science and technology is also a bit of a drawback. We do not know whether this industrial product is harmful or not suitable for us. Today I introduce you to Varnish.
What is varnish
In general, light oil is actually a synthetic resin, replaced by a tall expression method, that is, Varnish is a synthetic polymer polymer. For a long time ago, it was not called varnish. It was only called "Tung oil," because at that time in many places in rural areas, there was no condition to protect frequently used daily furniture accessories and it was painted directly on newly-made wooden barrels. Such things as tubs, etc., play a role in waterproof protection and make the life of agricultural tools longer. Today's varnish is a synthetic resin with natural resin properties. Some varnish oils even exceed the properties of natural resins and are therefore widely used in daily life. In the past, the composition of varnish was single, and the classification was unscientific. Nowadays varnish mostly refers to the surface transparent varnish, which is colorless and glossy after film formation. Therefore, it is called “varnishâ€, commonly known as varnish.
How to use light oil
1. We must pay attention to the requirements of the object to be coated when we mention how to use it. This is an important step that we must take. Varnish hardness and its abrasion resistance is much better than the color paint, is a very good protection of the paint species. The main thing is its transparency, and the surface of some items requires a coating of varnish, precisely because of its transparency.
2. When using varnish, we will also consider its feel. Glossiness is on the one hand, and the better hand feel is valued by some users. For example, the PU paint that we spray on the silicone part or the UV paint that is sprayed on the plastic part is such a varnish. In fact, the earliest varnish was tung oil. At that time, there was no synthetic resin.
3, before coating, we must consider the viscosity of varnish, and then there is to see the relevant instructions before painting. Adjusting the viscosity of varnish is a very important step. When adjusting, be sure to pay attention to even regulation, and you must not be free.
4, before the general Varnish re-apply to pay attention to sealing, otherwise we can not guarantee its use effect. When coating, pay attention to its uniformity and avoid bubbles or sagging. This is the problem of painting.
5, the coated items are generally floor, doors and windows, tubs, cars and the like, must be fully dry. Drying cannot be done by other means.
The role of varnish
1. As a transparent protective paint, its hardness and wear resistance are better than color paint, and play a protective role.
2. As a hand paint, its brightness and brightness are very good, and it feels good. For example, PU paint sprayed on silicone and UV paint sprayed on plastic parts are such varnish.
The earliest lacquer oil was tung oil. At that time, there was no synthetic resin, only earth paint, lacquer, and the like. In many places in rural areas, tung oil is directly brushed on newly-made wooden barrels, tubs, and the like to provide waterproofing, protection, and decoration. At that time, the use of tung oil was quite extensive. The lacquerer used the tung oil after processing it in furniture, architecture, fine arts and many other industries.
Summary: The above is the content of light oil and light oil used by Xiao Bian for everyone's introduction. Hopefully it can help you effectively. For more information, please pay attention to this website.
