Return to the exciting era of 1999

Chapter 644 Transformation and upgrade of glass wool factory, success
The inner cavity of the curing furnace is laying bricks, and various external accessories are just in time for maintenance.

"Xiaohou, change the flue of this blower from here to here, use this welding elbow to lead to this place, and make a second return cotton! In addition, add this air induction to the head of the return cotton air duct, and the suction section is here All the tops of the chimneys are sealed, lead from here to this place, and then make a large-scale back cotton."

"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 water used for cleaning 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 need to use this water for the ingredients in the future, understand..."

Anyway, the old production line had to be dried, and Ji Donglai gave Li Heping enough time to renovate. All those involved in serious pollution were collected and then returned to production for remanufacturing. The dregs of glass wool were 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 plan, it is easy to do it. Ji Donglai personally watched it, and everyone worked very hard.

As for the new production line, there is no trial production yet, and the oven is still in operation. After the planning of the old production line, Li Heping immediately started to transform this set, which is completely the same concept as the old production line.

After the transformation of this line was completed, all the production was switched to this side, and some parts involving electronic control were all done by Ji Donglai himself, and the progress only took seven days.

"This is good. The cotton return pipe is no longer blocked. It used to be blocked at least twice a day, but I was so desperate. Now there is not so much slag on the production line, and there is no need to cover it so tightly. It turns out Can it be changed?"

"That's right, Mr. You said that this can't be changed. Isn't this very good? It seems that there are still capable people in our factory, amazing!"

"Isn't it just to reduce costs? Look at the cotton used this time, how much money will the boss save in a year?"

"Isn't it? The boss will settle accounts, money!"

With Ji Donglai and several people adding waste cotton collection and recycling to the production line, the environment of the entire factory has been completely improved, and the glass wool scum flying around the workshop has been effectively controlled in minutes.

For the most difficult location of the side belts, Li Heping simply made a closed space, and the induced draft fan was pulled out for a circle, and then the wind force decreased, and then returned to the forming section.

Without the glass wool scum flying all over the sky, the workers are enthusiastic about their work, and the speed of the chain plate is faster, which invisibly lowers the production cost.

For the aluminum foil sticking process, Li Heping directly added an automatic feeding device, which no longer requires manual adjustments. As for the problem of the glue spray nozzle always being blocked, the other party simply added a nozzle with a self-cleaning function, and the three sets of nozzles were used in turn.

The transformation of this line is not limited to this. For the insulation of the kiln mouth, Li Heping bought ten imported silica bricks from abroad, the kind with insulation.With this improvement alone, the gas saved every day is enough for five families to use for three months, but these two bricks are really expensive, [-] US dollars each.

As for the temperature sensing element, Li Heping replaced the one on Ji Donglai's rubber testing machine. The temperature measurement system has been stabilized, and the previous situation of high and low temperature measurement has also been completely changed.

The entire new production line has been remodeled and is just in trial production, and the effect is significantly improved compared with the previous one.

Not only that, Li Heping added a new waste heat collection device behind the kiln, and added three waste heat boilers before the emptying device. Now all the hot water for bathing in the whole factory is used here.

The hot water used by Zhang Yu, the asbestos tile chief next door, is also imported here, which kills two birds with one stone.The living area is now also 24 hours hot water.

Most importantly, the waste heat boiler is used to heat the hot water pool, and various chemical raw materials are melted in advance, which shortens the batching time by one-third, and the waste rate of some instant materials is greatly reduced, which directly reduces the cost of raw materials by a large amount.

The waste heat heats the air entering the furnace in advance and pre-heats the gas, which not only improves the combustion efficiency, but also reduces the gas consumption by one-fifth. This cost saves Ji Donglai enough money to buy two Toyotas every month. Overbearing, the cost of water, electricity and gas has dropped in all aspects.

Looking at these data, Ji Donglai knew that he was definitely on the right track.

"Mr. Ji, in fact, the formula can also be changed. The formula adopted by Mr. You is traditional. Everyone used this formula when our reform and opening up started. Formaldehyde is mixed with ammonia water, and several other materials are added. The bonding performance is very good. good."

"But formaldehyde is very evil and has a lot of damage to the human body. Although we don't say it, it is definitely not a good thing. Now there is a material called modified peroxate, 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 has leveled off, and the toxicity has been reduced by more than 01:30. At least we don't need to wear a gas mask to work around. We can also use another new type of compound to replace phenol. I Knowing that Jingkai Chemical now has a patent, we can order from them."

The production line was basically modified, and Li Heping and Ji Donglai started to discuss the formula. These are all Li Heping's research results over the years, but the other party's boss didn't use it for the same reason: expensive!

Each ton of the product is more than 100 yuan more expensive, which is unacceptable in the eyes of the other party. After all, this thing is pulled away by a trailer every day. If it is pulled away by dozens of tons, that is money!
The increased cost of one car can be enough for three workers to pay wages, why change it?The state explicitly prohibits the sale of formaldehyde and phenol.

"Small batches have been successfully tested, and then large-scale changes will be made. The next step is to reduce costs. I will leave it to you. In short, there are two criteria for my next inspection. The first one is that my teacup has been open for three days, and there is no glass in it. Cotton waste; second, the production cost continues to decrease, this is the task entrusted to you."

Ever since he saw the glass wool scum in the health pot last time, Ji Dong has always worn a mask when he came to the glass wool factory, and he didn't eat or drink water. Now he has given the ultimate goal to Li Heping, and the rest is his own Let go of the shopkeeper.

Pushing open the window, the autumn tiger was not so rampant outside, Ji Donglai let out a long breath, at least the guilt feeling on the glass wool was a little less.

"Buzz..."

"Ji Liang, tell me!"

Looking at Ji Liang's number, Ji Donglai signed Li Heping's plan, and the other party went out with the plan. In fact, there was no need for small batch trial production, which was a waste of time. cutting costs.
