The inner cavity of the curing oven is being bricked, and the various external accessories are being overhauled.

"Xiaohou, change this blower flue from here to here, use this welding elbow to lead to this place, and make a second cotton return!" In addition, the head of the cotton return air duct adds this induced air, and the chimney here in the suction section is all sealed, leading from here to this place, and then making a large cotton return. ”

"The hot air is led to the large chain plate through the official road, the cooling effect of glass wool is better, the water used for cleaning should not simply settle, from here to here to make a return water, here to make a proximity switch, water level alarm, and use this water for ingredients in the future......

Anyway, the old production line had to be dried, and Ji Donglai gave Li Heping enough time to renovate, collect all the serious pollution and then return it to production and remanufacturing, and never let the dregs of glass wool fly outside the factory.

This kind of transformation is not a problem for the workers of one-yuan manufacturing, as long as there is a layout plan, it is easy to do, Ji Donglai personally stares at it, and everyone who works is very hard.

As for the new production line, there is no trial production yet, the oven is still continuing, and the old production line has been planned, Li Heping immediately began to transform this set, which is completely the same concept as the old production line.

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

"This is good, the cotton pipe is no longer blocked, it used to be blocked at least twice a day, but I was killed. Now there is not so much scum on the production line, and there is no need to cover it so tightly, can it be changed? ”

"That's right, you always said that this can't be changed, isn't this very good? It seems that there are still capable people in our factory, amazing! ”

"Not to keep costs down? You see that this time the cotton is used, how much money does the boss save in a year? ”

"Isn't it? Or the boss will settle the account, money! ”

With Ji Donglai, several people increased the collection and recycling of waste cotton to the production line, and the environment of the whole factory was completely changed, and the glass wool residue flying all over the workshop was effectively controlled in minutes.

For the most difficult to collect the side belt position, Li Heping simply made a confined space, and the induced draft fan was pulled out to turn around and returned to the forming section after the wind decreased.

Without the glass wool dregs flying in the sky, the workers are enthusiastic about their work, and the speed of the chain plate is faster, which virtually reduces the production cost lower.

In the process of pasting aluminum foil, Li Heping directly added an automatic feeding device, which no longer needs to be adjusted artificially, as for the spray nozzle is always blocked, the other party simply clamped a nozzle self-cleaning function, and three groups of nozzles are used in turn.

The transformation of this line is not only this, the insulation of the kiln mouth, Li Heping bought ten imported silica bricks from abroad, the kind with thermal insulation layer. This improvement alone saves enough gas a day for five families for three months, but these two bricks are really expensive, $10,000 a piece.

Li Heping replaced the kind on Ji Donglai's rubber testing machine, and the temperature measurement system was stabilized, and the previous situation of high and low temperature measurement has also been improved.

The whole new production line was renovated just in time for trial production, and the effect was significantly improved compared with before.

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

The hot water used by Zhang Yu, the chief of the asbestos tile next door, is also introduced here, killing two birds with one stone. The living quarters are now also hot water 24 hours a day.

The most important thing is that 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.

The waste heat heats the air entering the furnace in advance, preheating the gas, which not only improves the combustion efficiency, but also reduces the gas consumption by one-fifth.

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

"Mr. Ji, in fact, the formula can also be changed. The formula used by the general manager is traditional, and everyone used this formula when we first started the reform and opening up. Formaldehyde is combined with ammonia, plus several materials, and the bonding performance is very good. ”

"But formaldehyde is very evil, and it has a lot of damage to the human body, although we don't say it, but it is definitely not a good thing. Now there is a material called modified pelanoate, which is called modified formaldehyde in China. The price of this stuff is slightly higher than the price of formaldehyde, but it is non-toxic! ”

"We can also replace ammonia with other amines, the overall price is flat, the toxicity is reduced by more than a little bit, at least there is no need to wear gas masks around. We can also use another new compound to replace phenol, and I understand that Jingkai Chemical now has a patent, and we can order from them. ”

The production line was basically changed, and Li Heping and Ji Donglai began to discuss the problem of formula, which is the research result of Li Heping over the years, but the other party's boss did not use it, for no other reason: expensive!

Each ton of product is more than 100 yuan expensive, which is unacceptable in the eyes of the other party, after all, this thing is pulled away by a wheel trailer every day, and dozens of tons are pulled away, that is money!

The increased cost of one car can be enough for three workers to pay wages, why change? The state prohibits the sale of formaldehyde and phenol.

"The small batch trial was successful, and then it was changed on a large scale, and the next step to reduce costs is to be handed over to you, in short, I will test the standards next time. First, my teacup was open for three days, and there was no glass wool residue in it; Second, the cost of production continues to decrease, which is the task entrusted to you. ”

Since the last time he saw the glass wool dregs in the health pot, Ji Dong has always worn a mask when he came to the glass wool factory, and he didn't eat or drink water.

Pushing open the window, the autumn tiger outside was no longer so raging, Ji Donglai let out a long breath, at least the guilt on the glass wool was a little less.

"Buzz ......"

"Ji Liang, you say!"

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, wasting time, Li Heping directly began to purchase in batches, which invisibly saved a lot of costs.
