Bricks are being laid in the inner cavity of the curing furnace, and various external accessories are being inspected.
"Xiao Hou, change the blower flue from here to here, use this welding elbow to lead it to this place, and make a secondary cotton return! In addition, add this air induction to the head of the cotton return duct, and the suction section is here The top of the chimney is all sealed, and it is led from here to this place, and then a large-scale backfill is made."
"The hot air is led to the large chain plate through the official road, which has a better cooling effect on the glass wool. The cleaning water should not simply settle. Make a return water from here to here, and make a proximity switch here to alarm the water level. Do you understand that we need to use this water for ingredients in the future..."
Anyway, the old production line needs to be dried. Ji Donglai gave Li Heping enough time to carry out the transformation. All the products that involved serious pollution were collected and returned to production for remanufacturing. The glass wool residue was absolutely not allowed to fly outside the factory.
This kind of transformation is not a problem for the workers of Yiyuan Manufacturing. As long as there is a layout diagram, it is easy to do. Ji Donglai is personally watching, and everyone who works is particularly hard-working.
As for the new production line, it has not yet been put into trial production. The oven is still in operation. The planning for the old production line has been completed. Li Heping immediately started to transform this set, which is completely the same concept as the old production line.
After this transformation was completed, all production was switched here. Ji Donglai did all the electronic control aspects himself, and the progress only took seven days.
"This is good. The return cotton pipe is no longer clogged. It used to be clogged at least twice a day, but it was frustrating. Now there is not so much scum on the production line, and there is no need to cover it so tightly. It turns out that Can it be changed?"
"Yes, the boss said that this can't be changed. Isn't this great? It seems that our factory still has capable people. They are awesome!"
"Isn't it just to reduce costs? Look at how much money the boss will save in a year after using the cotton this time."
"Isn't that right? The boss still knows how to settle accounts, money!"
Along with Ji Donglai and several people, they added waste cotton collection and recycling to the production line. The environment of the entire factory was completely changed. The glass wool residue flying all over the workshop was effectively controlled in minutes.
For the side belt position that was the most difficult to collect, Li Heping simply made a closed space. The induced draft fan was pulled out and rotated around to reduce the wind force and then return to the forming section.
Without the glass wool residue flying in the sky, the workers are more enthusiastic about work and the chain plate can be driven faster, which invisibly reduces production costs even lower.
For the aluminum foil pasting process, Li Heping directly added an automatic feeding device, eliminating the need for manual adjustment. As for the problem that the glue nozzle was always clogged, the other party simply installed a nozzle with a self-cleaning function, and three groups of nozzles were used in turn.
The transformation of this line is not limited to this. For the insulation of the kiln entrance, Li Heping bought ten imported silica bricks from abroad, the kind with insulation layer. This improvement alone can save enough gas for five families for three months. However, these two bricks are really expensive, costing 10,000 US dollars each.
Li Heping replaced the temperature sensing element with the one on Ji Donglai's rubber inspection machine. The temperature measurement system was completely stable, and the previous high and low temperature measurement situation was completely changed.
The entire new production line was renovated just in time for trial production, and the results were significantly improved compared to before.
Not only that, Li Heping added a new waste heat collection device behind the kiln, and added three waste heat boilers before the evacuation device. Now all the hot water for bathing in the entire factory is used here.
The hot water used by Zhang Yu, the asbestos tile manager next door, is also imported here, killing two birds with one stone. The living area now also has 24-hour hot water.
Most importantly, a waste heat boiler is used to heat the hot water pool and melt various chemical raw materials in advance, shortening the batching time by one-third. The waste rate of some instant materials is greatly reduced, which directly reduces the cost of raw materials.
The waste heat heats the air entering the furnace in advance and preheats the gas, which not only improves the combustion efficiency, but also reduces the gas usage by one-fifth. This cost saves Ji Donglai every month enough to buy two Toyotas. Overbearing, all aspects of water, electricity and gas costs have dropped.
Looking at these data, Ji Donglai knew that he had definitely taken the right step.
"Mr. Ji, in fact, the formula can be changed. The formula used by the president is traditional. Everyone was using this formula when we first started reform and opening up. Formaldehyde is mixed with ammonia, and several other materials are added, and the bonding performance is very good. good."
"But formaldehyde is very evil and has a lot of harmful effects on the human body. Although we don't say it, it is definitely not a good thing. Now there is a material called modified peroxylate, which is called modified formaldehyde in China. This thing The price is slightly higher than the price of formaldehyde, but it is non-toxic!”
"We can also replace ammonia with other amines. The overall price will be flat and the toxicity will be reduced by more than a little. At least we don't have to wear a gas mask to work around. We can also replace phenol with another new compound. I learned Jingkai Chemical now has a patent, and we can order from them."
The production line was basically modified, and Li Heping and Ji Donglai began to discuss the formula. These were the results of Li Heping's research over the years, but the other party's boss did not adopt it for no other reason: it was expensive!
Each ton of product is more than 100 yuan more expensive, which is unacceptable to the other party. After all, this thing is hauled away by a wheel trailer every day, dozens of tons, and that’s money!
The increased cost of one vehicle can be enough to pay three workers, so why change it? The state explicitly prohibits the sale of formaldehyde and phenol.
"The small batch trial was successful, and then we will make large-scale changes. The next step to reduce costs is up to you. In short, there are only two standards for my inspection next time. The first one is that my teacup has been open for three days and there is no glass inside. Cotton scum; secondly, production costs continue to decrease, which is a task entrusted to you."
Since the last time he saw the glass wool residue in the health pot, Ji Dong has always worn a mask when he came to the glass wool factory, neither eating nor drinking water. Now he has given the ultimate goal to Li Heping, and he will do the rest. Hands off the shopkeeper.
Pushing open the window, the autumn tiger was no longer so rampant outside. Ji Donglai took a long breath, at least the feeling of guilt on the glass wool was reduced.
"Buzzing..."
"Ji Liang, tell me!"
Looking at Ji Liang's number, Ji Donglai signed Li Heping's plan, and the other party took the plan and went out. In fact, there was no need for small batch trial production, which was a waste of time. Li Heping directly started to purchase goods in batches, which invisibly saved a lot of money. cut-off cost.
