Perfection of Rebirth

Chapter 812 Continue to Visit
Throughout the morning, Jiang Hui, led by Pi Wei, Kato and others, visited the stamping and welding workshop of Brilliant Automobile, and had dinner at the temporary cafeteria inside Brilliant Automobile at noon.

Although the Brilliant Automobile Base has not yet been fully constructed, many people work here every day. The problem of eating must be considered, and the temporary canteen came into being.

"When our canteen is outsourced to other companies, we must choose a brand-name company, and we can't save money." The food in the temporary canteen can't be said to be delicious, nor can it be bad.

However, for Brilliant Motors, which will have tens of thousands of people in the future, the construction of canteens is actually not a small problem.

In the cycle of eating, going to work, and sleeping every day, eating is a frequent occurrence. If you eat poorly, it will affect your work efficiency.

It's like some consulting companies stipulate that a flight of more than four hours must book business class instead of economy class, because they think it will affect work efficiency.

Compared with the labor cost of the entire company, Jiang Hui felt that the cost of a little food was still unavoidable.

"Understood, we have already selected two suppliers. Canteen No. [-] and Canteen No. [-] will be operated by them respectively. By then, dishes from all over the world can be found in the canteens," Pi Wei said.

"It's good to use the two together. Everyone has competition. Only with competition can we make progress. Otherwise, even if the dishes are good at the beginning, the level will drop slowly when the inertia increases," Jiang Hui said.

The importance of competition is unquestionable. If you look at the things you encounter in your daily life, the prices of those with full competition are relatively reasonable, and those of monopoly nature...

China's oil price is the most obvious representative, and of course the price of salt.

"Yes, we think so too, and our contract is signed once a year. If employee satisfaction is very poor, the contract will not be renewed in the second year."

After dinner, everyone didn't take much rest, and then went to visit the factory.

Adjacent to the welding line is the paint shop.

After the body-in-white is manufactured in the welding workshop, it will be directly transferred to the painting workshop by the conveyor chain.

"Mr. Jiang, after our body-in-white arrives at the painting workshop, we will firstly carry out pre-treatment in this area. There are basic processes such as washing, pre-degreasing, degreasing, surface adjustment, phosphating, and passivation. The main function is to remove the surface of the body. The oil stains on the body form a smooth phosphating layer to facilitate better electrophoresis and increase the adhesion of the electrophoretic paint," Pi Wei said, pointing to an area under construction inside the painting workshop.

The painting workshop, as the name suggests, is a workshop for painting cars.

For the colorful cars we usually see on the road, the colors of the body parts are all sprayed in the paint shop.

As we all know, the use of automobiles is very complicated. Whether it is windy and rainy or hot sun, whether it is tropical heat or northern cold, whether it is an area with abundant salt by the sea or an area with low pressure on a plateau, cars are all in use.

Since the use situation is so complicated, in addition to the high requirements on the performance and stability of the car, the paint quality of the car cannot be ignored.

You must know that most of the car bodies are made of iron. Iron will be corroded when exposed to the air. If the key corrodes seriously, it will be dangerous, dangerous...

It could be fatal!
Naturally, the technical requirements for automobile painting are very high. It can be said that among general industrial products, automobile painting requires the highest comprehensive performance requirements.

Not only should corrosion resistance be considered, but also stone chip resistance, high and low temperature resistance...

In this way, the importance and technical content of the painting workshop are self-evident.

"After the pre-treatment is completed, electrophoresis and water washing are carried out. Electrophoretic paint is the first layer of paint film on the steel plate of the car body. Its main function is to prevent corrosion, dry, polish, and remove electrophoretic sag and the sheet metal and PVC left over from the car body. and other flaws," Pi Wei continued.

"The next step is the sealing line, which seals the gaps in the body to prevent water and air leakage and sound insulation, and then the intermediate coating. The main functions of the intermediate coating are stone impact resistance, UV resistance, drying, grinding, and removal of intermediate Defects such as sagging and sealant caused by coating.

"Then the topcoat is sprayed, which is divided into color paint and varnish. Needless to say, the color paint determines the color of the car body, and the varnish is mainly to increase the gloss of the car body, chemical resistance, weather resistance, and durability. Corrosiveness, but also a certain degree of hardness and flexibility," Pi Wei continued.

"Most of the paints and solvents used in the painting workshop are toxic substances, right?" Jiang Hui asked.

"Yes, various paints, etc. form paint mist, organic solvent vapor, and dust during work. Long-term contact and inhalation by operators can cause chronic poisoning and damage health. Working in a painting workshop for a long time may produce different degrees of Chronic poisoning.

Mild benzene poisoning: headache, dizziness, general weakness, fatigue, drowsiness, palpitations, loss of appetite, etc., and occasional nosebleeds and bleeding gums.

Moderate benzene poisoning: white blood cells drop below 3000, red blood cells and platelets decrease, nose and gums bleed frequently, subcutaneous congestion and purple spots may appear, women's menstrual period is prolonged, and resistance decreases.

Severe benzene poisoning: white blood cells drop below 2000, red blood cells and platelets decrease greatly, oral mucosa and subcutaneous hemorrhage, extensive retinal hemorrhage, liver enlargement, significant changes in bone tissue, multiple neuritis, aplastic anemia, etc.", Kato aside explained.

"The regulations in our painting workshop are that when performing rust removal, grinding, spraying and other work, you must wear protective glasses and filter masks to prevent sand and paint mist from damaging your eyes and respiratory system.

When using pickling or lye to remove rust, acid-resistant gloves and protective glasses should be worn.

When using double-part paint, especially paint containing isocyanate, it must be carried out in a sealed spray booth with a good ventilation system, and operators must wear activated carbon filter breathing masks or air supply masks," Pi Wei also explained on the side.

"The most important thing is that our painting production line is the most automated among all production lines, and the paint we use is also water-based paint, so we can avoid the occurrence of occupational diseases from the source as much as possible," Kato said.

"Water-based paint? Is there any difference from ordinary paint?" Jiang Hui looked at Kato with a questioning expression.

"If you want to talk about the difference, the most obvious thing is the price. Water-based paint is more expensive, but it is more environmentally friendly," Kato said with a smile.

"Water-based paint uses water as the dilution solvent, and its ultra-low VOC content is lower than the national mandatory standard of 200mg/L. It is a truly non-toxic, tasteless, high-tech and environmentally friendly product.

Ordinary oil-based paints use organic solvents as diluents, and their products contain benzene, toluene, xylene and their derivatives. In addition, polyester paints also use curing agents, so the toxicity of polyester paints is the highest, and nitro The toxicity of the paint is second,” interjected the project manager next to Kato who was in charge of the construction of the paint shop.
