Where is the hand - paste process tomorrow

In the 1930s, with the advent of glass fiber and unsaturated resin, FRP began to emerge in the material world. By virtue of its excellent performance, the continuous curve overtaking, the latecomers to the house. As a also not the one hundred - year - old material, its application field contains almost all industry, aerospace, military industry, wind power, rail transportation, automobiles, yachts, fishing boats, recreational supplies, sports equipment, construction industry, sanitary ware, and various industrial fields. You can say that, you can think of, and unexpected industry, all have glass steel figure.

Glassfiber Reinforced plastic, Glassfiber Reinforced Plastics. Simple understanding is glass fiber and resin, plus some auxiliary materials, through a certain molding process to combine them together to form a new material with excellent performance. From the beginning of the hand paste process, the continuous evolution of RTM process, vacuum technology, jet technology, pulping process, winding process, molding process and so on.

Today, longbow came to talk to you about the "old man".

01

In 1940, the United States made a fiberglass military aircraft radar cover with a hand paste process, which has been accompanied by the development of FRP .Although many new processes have emerged and the raw materials have undergone many changes, the hand paste process still occupies an important position. The reason is simple, because the advantages of the hand paste process are obvious. There is no need for complicated equipment, only the mold and simple tools, the investment is less quick. The production technology is easy to grasp, after the short - term training can be operated. The products are not limited by shape and size. It can be combined with other materials (such as metal, wood, foam, etc.).For large products that are not easy to transport, they can be made on site.

With these advantages, hand paste technology once occupied 70-80% of domestic industrial production .Although in recent years, with the mature application of other technologies, the proportion of hand paste technology has been decreasing year by year, but more than half of the production will be applied to the paste technology.

02

But the seemingly prosperous surface, the winter has quietly arrived. Last year, when the environmental protection wind was blowing, the enterprises that did hand paste technology were the first to rectify or shut down. There were no two words. The reason is very simple, although the hand paste process has many advantages, but the disadvantages are also obvious. The quality of the products is unstable. Due to the technical level of the operator and the impact of the site environment, the product quality stability is poor. The resin content is large, not suitable for high-intensity products .Low production efficiency, long production cycle, not suitable for mass products. It has large smell, much dust processing and bad production environment.

So now just said to paste process, a lot of people in the mind of the scene must be considered the environment, several technical workers are heterogeneous in your working habits. A: I got a small prize in the lottery last night. I was in a good mood and I was really busy with the bubbles .B in the morning before leaving the door and wife bicker, the mood is low, casually make two, have bubble also be lazy to reason.

In this way, I do not know when the hand paste process is old and traditional technology and low quality are equated.

03

As the environmental requirements become more and more demanding, it can be predicted that the living space of the hand paste process will be further compressed .Many companies choose to hand lay-up process because of low cost, and most are not high value-added products, if they invested large sums of money to make environmental protection equipment, a strong will consider other upgrade transformation process directly, no power or secretly do, or we can only wait for the fail.

Another very serious problem is the declining number of practitioners. The average age of these hands is now about 40 years old, and very few people are willing to do the dirty work after 80, and almost no after 90.With the gradual retirement of these people, the phenomenon of no one is inevitable, which is why many enterprises now face the difficulty of recruitment.

It may be years later that the hand - paste process will leave the stage of history for these problems.

04

The hand paste process is like a late hero, one day old, even if the heart is willing, but not enough. So someone looked down on the former hero and laughed at his low skill. Yeah, that's not what it was. Year after year, day after day, still the same .But you guys only rely on equipment, do the people who depend on the system really understand the hand paste process? If you can't make a hand paste process, you can also say that it is a joke.

Indeed, the hand - paste process has various problems and is increasingly unsuitable for this era. He will be old, but the principle behind that trick is still worth learning and probing, because it is the core principle of FRP. The principle makes it clear that you can challenge different processes. So, don't laugh, it's really dirty, but the real hand - paste process should be awe-inspiring, but a lot of people just suck it up.

By the time he gets old, the hero will remember 1940, the soaring radar dome.

05

Every person who really understands the process of hand paste is the monk who lives in seclusion.
