Summary of the Causes of Walnut Cracking in Wan Wen;
To understand why Wanwen Walnut cracks, we must first understand what Wan Wen Walnut is. In fact, Wan Wen walnut itself is a kind of wood, which is not much different from other wood. Since it is wood, like olivine and king kong, there is a great possibility of cracking. The causes of walnut cracking in Wan Wen are the same as those of wood, wind and water.
Fear of wind and water is a characteristic of Wan Wen walnut before coloring, which is an unavoidable problem for any so-called walnut expert.
1, walnuts are the easiest to crack as soon as they get off the tree!
After Wan Wen walnut leaves the tree, it must go through the process of peeling green skin and brushing walnuts. This process meets water. Walnut itself has just left the tree and also contains a lot of water! Therefore, at this time, if you want to dry walnuts in the shade, you should put them in a sealed bag and try not to expose them to the outside world to avoid the wind. It is easy to crack at the sight of the wind at this stage. This crack may be a matter of an instant. Therefore, at this stage, larger nuclear suppliers will be very cautious about receiving high-quality products and make good use of sealed bags and boxes.
2. 10 month, the climate difference between north and south is huge, which is easy to cause cracking!
After many nuclear friends bought walnuts, they harvested them well at that time and didn't want to crack after a day. Here, it is not only the nuclear friends who expose walnuts to the outside world too much, but also the differences between the north and the south. Wan Wen walnut boutique distribution center is mostly in Beijing, so we will analyze it with Beijing as the center.
Further north of Beijing, there are Liaoning, Jilin, Heilongjiang, Inner Mongolia plus Gansu and Xinjiang. The climate changes violently, the wind is stronger, it is colder than Beijing, and the temperature difference is greater. At this stage, Wan Wen walnut is not suitable, and the huge temperature difference will lead to contraction or expansion. If you don't put it in a sealed bag, kit or gift box, and put it on the table too much, it will easily crack in the wind, rain and sun.
Beijing faces south, with humid climate and high water content in the south. The month of June 5438+00 in Beijing is already very dry. Wan Wen Walnut is afraid of two things, wind and water. The excessively humid air in the south caused Wan Wen walnut to absorb more water through the wooden holes in the air, which led to expansion and easy cracking.
3. It is easy to crack before and after heating in the north.
Just in winter, heating began in the north, which directly led to the very dry air inside the house. It is common that the exposed walnuts are cracked by excessively dry air. This is like a solid wood floor laid at home, which is afraid of water and heat and cracks and deforms.
The above three conditions are the reasons why Wan Wen walnuts, especially new walnuts, are easy to crack. But what about crushed walnuts?
Common treatment methods of Wan Wen walnut after fruit cracking;
What should I do if the walnut cracks? Many nuclear friends are very angry. In fact, the handling method is not complicated and relatively simple.
Soak the cracked walnut in water for 10 minute, then take it out, dry the water outside the walnut, seal it in a sealed bag, dry it in the shade for 12-24 hours, and then take it out. Generally speaking, walnuts will heal themselves at this stage. This method is very effective for walnuts that crack along the grain.
This kind of repair is not only invisible, but also unlikely to crack again. It should be said that this kind of restoration is very common in walnut circles in Wan Wen.
Regarding the problem of 502 glue, according to years of experience, walnuts that have used 502 glue are colored with normal walnuts in the process of playing, and there is no difference in patina. Simply put, you can't see that the glue has dripped. Many times, only people who have lost glue know. If he doesn't tell, no one else will know. But the walnut coated with 502 glue must be new and unused. Once colored, there will be sweat or dust in the cracks of walnuts, and the glue effect will be weak or even ineffective. Therefore, cracking and curing are mostly tricks played by nuclear dealers themselves.
About the skills of dropping 502 glue by nuclear traders, popularize it for the majority of nuclear friends. Find a toothpick, drop 502 glue, and let 502 glue penetrate into the gap of walnut along the toothpick. It's that simple. Repairing cracked walnuts in this way is firm and safe, and you can't see it.
