Zhang Xiaofan's idea is naturally good, but before that, Liu Pingfeng's matter must be solved first.

Although wooden furniture is a relatively large industry, it is difficult for Zhang Xiaofan to have the confidence to promote this wood powder coating.

After all, the wooden furniture industry is too mature, 95% of them are using paints and coatings, and it is really too difficult for so many people to change their past habits at once.

But there are several of them in their own company, and the customers who make and sell furniture, whether they can do it or not, call them over for training first, Zhang Xiaofan thought.

But before that, there is a very important issue to be solved.

First of all, it is necessary to find a set of effective technological processes for these manufacturers.

After all, for spraying wooden furniture, it is also a relatively new method, and basically most furniture manufacturers use paints.

If you want them to change from oil to powder, the process should be very difficult, you have to let them see the benefits, for a manufacturer, the biggest benefit is the cost reduction.

Therefore, Zhang Xiaofan summarized the requirements of this process, and there are two most important points.

The first is the simplicity of the process.

The second is that the cost should be low.

The process is too complex, so that the fault tolerance rate of the whole process is reduced, and the complexity is simplified, which has always been a necessary lesson for every production company in his life.

If the cost is very high, don't think about it, they will definitely not accept the oil to powder.

Oil-to-powder has always been vigorously promoted in many countries, mainly for environmental considerations.

Although there is a lot of selfishness in it, it is to increase the sales of my company, but in any case, I have contributed to environmental protection by promoting this matter.

For the sustainable development of human beings, Zhang Xiaofan is also open-minded.

This time you are personally involved and research something like this, and if you have no exposure to the industry at all, you can imagine how long the research will be.

Zhang Xiaofan couldn't wait, so Zhang Xiaofan was ready to play in person.

First determine a general direction and determine a necessary process.

Now the technical team of Zhimei New Materials has been very large, basically 90% of the technicians are bachelor's degree or above, and there are a few master's degrees.

Although the laboratory has not yet been formally established, it has already begun to take shape.

The research room that Zhang Xiaofan wants is not to study the formula he gave, but to really study some coatings that can change the times.

Liu Qi or some other technicians, at least Zhang Xiaofan has not found anyone who can host this project, so he can only wait.

Every year, the technician Zhang Xiaofan will personally take the school examination to see if there are those technical experts, a person who understands the real paint very thoroughly, and has some management ability.

For this point, Zhang Xiaofan himself is self-aware, if it weren't for that memory, he would probably be useless, at most like Liu Qi now, doing other people's hands and feet.

Zhang Xiaofan divided the entire production process into several stages, and then several different people, led a group, and carried out their own public relations.

When people were summoned, Zhang Xiaofan began to assign tasks.

First of all, the whole process is divided into two parts.

The first part is the pre-treatment part.

The second part is the paint spraying part.

The difficulty must be in the first part, this pre-treatment, not simply cleaning the surface of the furniture, I want to conduct conductive treatment.

This is to apply a conductive basic coating on the surface of furniture, and the requirements of this layer of coating are more troublesome.

First of all, he must be electrically conductive, and secondly, he must have very good adhesion to the paint and wood, and it must be easy to construct, after the construction is completed, the surface flatness must meet the requirements, and it can still be maintained under the high temperature of 160 degrees.

However, at present, there is a very big difficulty, the wood will deform at a temperature of more than 100 degrees, because at such a high temperature, the moisture loss of the wood will be more serious, which will lead to deformation.

So in the choice of wood, this is a relatively big problem.

At present, the wood that can not be deformed at high temperatures, Zhang Xiaofan can think of fiberboard.

Among them, both performance and price are MDF, that is, MDF, that is, medium density fiberboard.

MDF is made up of wood fiberboard and a resin binder.

The comprehensive properties of this wood product are very excellent, and the uniformity is much better than that of natural wood, which is very suitable for coating by solid powder electrostatic spraying process.

Therefore, the wood chosen by Zhang Xiaofan is also this kind, medium-density fiberboard.

If the requirements for furniture are not very high, you can use one-time spraying.

It is not to do unnecessary pre-treatment, that is, only the dash panel is frosted and then smoothed.

The painting process is also relatively simple, the wood is preheated first, the temperature is about 110 degrees, and then sprayed.

The finished surface is not a very flat type, with a little bit of orange and a little bit of sand.

It can only be used as a spraying method for low-end furniture, and there is not much to study.

But Zhang Xiaofan still assigned four or five people to conduct research, in order to make the process clearer and clearer.

There will still be a very large market for low-end furniture, so this process should at least be familiar with it to prevent customers from having this kind of low-end furniture in the future.

Zhang Xiaofan focuses on the process of medium and high-end furniture coating.

The focus of this spraying is on the pre-treatment.

The pre-processing is a two-step process, so there are two group leaders.

The first step is to frost the surface of the dash panel.

The purpose is to smooth the surface of the fiberboard, so that the subsequent process is easier.

The most common thing we do is to use sandpaper to rub the surface by hand, and of course you can also use mechanical tools.

The second step is more troublesome.

The first step is to lay the foundation for the second process, and the second process is to make it easier to spray powder coating on furniture, so that the paint coating can be cured to achieve the predetermined effect.

This process has a proper term called the substrate closed pore process.

We all know that the surface of wood is easy to form uneven surfaces, even if it is frosted, it still feels like it is frosted.

This requires a process of sealing the pores on its surface.

According to Zhang Xiaofan's memory, there are about three methods of this process.

The first is UV (ultraviolet light curing) primer, the second is PU (polyurethane, this belongs to liquid coating), and all three are conductive primers.

In terms of the current degree of scientific and technological development, the first two cannot meet the requirements, so the main research is the direction of conductive primer.
