Follow up on the hot edge experiment: hot edge test of two edge oils

Author: Left and Right Leather Products Weibo: https://www.weibo.com/u/3321891714 Last time I was bored and wrote an article about how to achieve hot edges with a low-priced electric soldering iron, "How to achieve hot edges for 50 yuan" http:/ /www.pixiaojiang.com/topic/show/444 Some leather friends raised their own questions. Originally, this is not my area of ??expertise, so I shouldn’t answer blindly. But I am always full of curiosity about unknown fields. Since I don’t know, I should give it a try~~ So this follow-up experiment was born during the National Day holiday. The main contents of the experiment are two points: 1. Can the quick-drying water-based edge oil that cannot be ironed be used to iron the edge with an electric soldering iron? 2. How to use a soldering iron to oil the wood while ironing it, and how should we solve the problems we encounter? Because I didn’t have wood edge oil on hand, I bought one just before the National Day holiday to try it out, so I started experimenting~

The picture above is the two protagonists of this experiment. The red one on the left is the water-based quick-drying edge oil I bought in the past. The merchant It is specially marked that this edge oil is a non-scalding edge oil, it is just a quick-drying water-based oil. On the right is the black wood edge oil I bought this time, in a small 60ml bottle. Let’s talk about the feeling of this black wood edge oil first. Compared with the ironing edge oil used in the previous test in the article, I feel that the wood edge oil is thicker and more gelatinous in texture. The result is that when applying edge oil with a duckbill pen, it can be applied very thickly at once, and the gelatinous texture allows the edge oil to easily hang on the cut surface of the leather.

Prepare two Start experimenting with the fitted leather.

Two sides The drying speed of the oil is quite good. This test was not very rigorous. I only applied the edge oil twice in total, not three times like last time, because it felt like two times was enough in terms of thickness.

After the edge oil has dried, you can see that even though the leather cut surface is already very neat, the edge oil needs to be edged twice. After the oil dries, there is still a slight collapse in the adhesive joint of the leather. This is also one of the functions of repairing the edge oil by ironing the edge later. If you compare the effect after the oil dries in the previous article, you can still see that the wood edge is oily. The difference is that after drying, the wood edge oil itself already has a certain luster, and the collapse is more obvious. I am not professional in this area, so I don’t know if this is due to the difference in ingredients. Here is a picture of the previous text Picture.

You can compare the effect with wood edge oil.

Then I started experimenting. Before buying wood edge oil, I asked about the suitable temperature for ironing, but the merchant replied that 4 levels of temperature can be used, but this is not a professional edge ironing machine. How can I know 4? What is the setting temperature?! I can only test it slowly by myself. In this case, I discovered another characteristic of wood edge oil: the hot edge temperature is higher! It is difficult for this edge oil to work below 300 degrees, and the soldering iron scratches When applying edge oil, the reaction of the edge oil is very small. Unlike the edge oil mentioned in the previous article, which can be easily melted, the edge oil can only react after adjusting the temperature to above 385 degrees.

A netizen once asked why The electric soldering iron will produce a lot of pits when soldering the edge. I asked if it was because the blade was too sharp. This is also something I bought wood edge oil to test and find out. After my own actual use, based on my superficial knowledge Based on my knowledge and experience, I feel that the problem may lie in the following aspects: 1. The temperature is not adjusted high enough to allow the edge oil to repair and melt immediately. If the edge oil does not respond, the producers habitual operation will stop, causing stagnation. That little bit of temperature rise creates potholes.If the temperature is enough, the oil will melt and repair the scratched edges, leaving no potholes. 2. If you really care about the cutting edge of the blade, you can use the position of the protective tube in the red circle in the picture above to iron the edge. 3. When ironing, the technique must be smooth, the angle and speed of the cutter head should be consistent, and the largest contact surface should be used to contact the edge oil.

After ironing black edge oil. As you can see from the picture, the two ends of the leather were when I started the experiment. The pit marks appeared due to the low temperature. Once the temperature reaches a high enough temperature, such marks will be avoided.

This is this The second purpose of this test is, can water-based edge oil that cannot be ironed be used to iron edges? The answer is that it can be ironed, but the effect is very unsatisfactory. 1. Although the edge oil will react at high temperatures, it cannot have a repair effect. From the picture above, you can see that the dent in the bonding area has not been ironed out. One of the main reasons for ironing the edge is The purpose was not achieved. 2. After ironing, edge oil will stick to the soldering iron, but edge ironing oil rarely leaves a large amount of residue on the soldering iron. So it turns out that there are still specialties in the art industry, and different tools and materials naturally have to be used in places suitable for their positions.

The last one For the wax step, I found out the past Columbus and ironed it and tried it again to see the effect. It turns out that the effect of Columbuss hard wax is indeed different from the previous wax.

The above is before Although I may not have found the real answer through the additional tests, at least I have gained a better understanding of the matter of hemming through the tests. It seems that simple ironing will produce too many changes depending on the materials and tools. This is also the most fun part~~~~~
