Tracing paper knowledge, you ask me to answer
When I was a child, I used M&G morning tracing papers to copy Zhao Mengfu and Wang Xizhi's calligraphy masterpieces. After I grew up, I used this tracing paper to describe cartoon paintings and completed their own designs. Today, Xiaobian came to talk with you about the little knowledge of tracing paper. You asked me to answer the little game. I hope that you can have a certain understanding of tracing paper through this little game.
First of all, I have to understand why the tracing paper is transparent. In the past, M&G morning tracing papers were often used to describe how to make paper transparent. The original secret is that such tracing papers generally contain a certain proportion of water, and the plain white paper is slightly transparent after soaking. This is the truth. The higher the water content, the better the transparency, but it is also more susceptible to moisture and is not conducive to preservation and use. A suitable moisture content is between 4% and 6%. Because of the water content, tracing paper is very sensitive to humidity. Moreover, the raw material requirements for tracing papers are also very high and must be made of pure wood pulp, the purity of which depends mainly on the quality of the wood pulp. The coniferous forest has a fine wood structure and a long fiber, which is the best raw material for making tracing paper. When identifying the purity of the tracing paper, the tracing paper can be pointed at the sun, no impurity spots, uniform light transmission, white and not gray.
What problems should you pay attention to when tracing papers are saved? In the past, Xiaobian often encountered the problem that M&G morning tracing papers that I bought could not be used after a few days. A large part of the reason was improper preservation.
1. The ambient temperature is preferably maintained between 23 ° C and 30 ° C and the relative humidity is controlled between 45% and 65%.
2. When using, use a pack/roll to open a pack/volume. Place the tracing paper in the use environment for 24 hours before use to prevent curling or crispness caused by sudden changes in temperature and humidity.
3. Before using the flat tracing paper, you should first open the package and shake it to prevent static adhesion.
4. It is difficult to distinguish between the front and the back of the drawing. However, due to the large difference in the smoothness of the front and back of some brands, the effect is different, so pay attention to distinguish.
5. Design drawings are the soul of engineering, and many design drawings require long-term preservation. Acidity is the enemy of the life of paper products. When the acid-containing paper is left for a long time, it will turn yellow, become brittle, and even have ink fading. The tracing paper must be completely neutral and acid free before it can be stored for a long time.
Moreover, there are certain skills for the selection of tracing papers. To use tracing papers to achieve different effects, it is necessary to use tracing papers of different specifications. For example, if you need to draw with tracing paper, then you can use low-quantity, usually 50g/m2, 55g/m2. For engineering copiers, it is necessary to use tracing papers of 63g/m2 and above. If the basis weight is too low, wrinkles and curls will occur. The more quantitative the tracing paper is less sensitive to humidity, like Xiaobian I will often use high-quantity tracing papers on the market such as M&G morning tracing papers, Kangmeilian, Geweit and other tracing papers.
Do you understand all the little knowledge about tracing papers that Xiaobian shared with you today? I hope that I can help you to purchase tracing papers and save tracing papers later.
