Many manufacturers who use waterproof agents have such experience, that is, under the same prerequisite, it seems that the waterproof cost of summer is much higher than usual. Many people’s first instincts are the waterproof corner of the supplier in summer. In fact It is normal for the idea, so what’s going on? Today we will analyze this phenomenon:
Analysis of the situation:
First of all, it does not rule out the problem of waterproofing agent. How to confirm or eliminate the product problem of the supplier? In fact, it is very simple. As long as we compare the difference between the first batch of sample samples and the current difference, this is easy to achieve (the waterproof agent is that it is The most intuitive and easiest product of the printed and dyeing aids is also very important. Before talking about this problem, we must figure out a fact that the cost of waterproof agent is not only determined by the waterproof agent itself, but also the waterproof agent itself, but also the waterproof agent itself, but also the waterproof agent itself, but also the waterproof agent itself. The influence of many other factors (the following analysis below), all the reasons that if they do not rule out the interference of these influencing factors and find the waterproofing agent directly, I think there is something wrong with our direction, which will not solve the problem. Some dye factories do well in this regard. The big goods will be tested on a regular basis, and compare with the first deposit (this is the raw material review. All of our raw materials are also done), so that you can accurately find the right problem point and solve the problem according to the specific situation.
Question one:
So what factors will lead to high costs in summer? We think we need to give priority level:
The first rushing in the first place should be the temperature. The friends of our dyeing factory have this experience, that is, as the temperature rises, the cost of waterproofing agent is gradually rising. Basically The month is sometimes 678 three months, and sometimes it is 789 three months. Basically, the waterproof cost of the month is at the top of the parabolic line. Then, as the temperature decreases, it will slowly return to the normal level.
This is experience, so is there a theoretical foundation? Of course, we all know that the same waterproof fabric is completely different if the evaluation results of different water temperatures are evaluated. For example, a 1 -level waterproof surface of the initial 5 degrees of water is tested by 25 degrees. If we change it now, we change it now. How much do you think of? Why is the same fabric so different? This involves the two basic mechanisms of the waterproof agent, which is the question of surface tension and contact angle.
(Friends who are interested can find information to see, so I will not go deep here)
Because the same water, 100 degrees of water is much smaller than the surface tension of 25 degrees, and the mechanism of waterproof fabric waterproof is that the higher the surface tension of the water, the greater the waterproof contact angle, and the better the waterproof effect. Then in this case To ensure that the waterproof effect can only increase the amount of waterproofing agent, the cost will naturally increase.
In addition, according to the experience of waterproofing agent application for so many years, all waterproof agents (including products of well -known foreign brands) are worse than low temperatures at high temperature environments, which is also the phenomenon we see in the laboratory in the laboratory. It is the same waterproofing agent and the same fabric. It may take 1%of the amount in winter to reach 100 points, and it takes 1.5%of the same 100 points in summer, or more. To further explore, no matter what the reason, the impact of temperature is certain. In this regard, some dyeing factories have long been recognized to the importance of temperature. The prophets are aware of it. Therefore, all the setting machines use condensate water as soon as the summer. All of our dyeing factories learn from.
Question two:
In the second place, we think that the waters of the fabric are clean. This is very important. There are two aspects of the impact. One is the cost. This is very simple. When the water is not clear, the amount of waterproofing agent should be increased, which is easy to understand; The second is the waterproof effect. This is the most fatal. We often do carbon eight waterproof factories. Sometimes it is not very deep. Factions that often make orders are used to use six carbon and fluoride waterproof factories (six carbon and fluoride non -fluorine -free relative Eight carbon is disturbed by water, especially fluoride). I believe that the problems in this area will be very prominent, and it will often be extremely difficult to waterproof on some cloth. In this case, many people are desperately desperately desperately. Increase the dosage, double it, and double the cost. Many dyeing factories will say that waterproof waterproof is not good. Waterproof agent is exchanged or unable to find the ideal product. If it is holding this idea to solve the problem, I think there is no solution, because your roots are not solved, even Now it is solved temporarily, and similar problems will occur, so where is the root, the root is out of the water, so where is the water out of the water? Here you can pass by).
Fortunately, more and more owners of the dyeing factory are aware of the critical water outlet. Most of the dyeing factories are equipped with waterproof special washing machines. While alleviating the pressure of the dyeing cylinder, it can also significantly improve the degree of waterproofing.
Problem three:
Other cost influencing factors, such as sticking rollers (can refer to the hazards of the waterproofing roller I wrote before); processing varieties and specifications (such as the low weight of the processing grams before, the high weight is now high, the cost will be high; for example, the cost will be high; for example, the cost will be high; for example, the cost will be high; Chunya spinning is mostly easy to waterproof, and now the difficulty of polyetapfa, memory cloth, and other materials are mostly materials, the cost will be high), and customer requirements (such as routine waterproof normal manufacturers 2-3 are normal. Waterproof also achieves 3-4 or 4 or more, that is, the cost of waterproof at the cost of strong waterproofing), and the use of the auxiliary agent (the most conventional such as static electricity, soft agent, tearing improvement agent, etc. The doses are negatively impact on waterproof. Simple to say that it will increase the cost of waterproofing)
