Now do you use a vacuum extruder for PU work?

It's not a vacuum extruder, it's a vacuum sink.

It's not a vacuum extruder, it's a vacuum sink. So far, I'm still doing it a lot!!

The extruder has a great function of devolatilization, but the smell of the product is not only related to the VOC of the material, but also has a greater relationship with the odor source of the material, that is, which type of substance causes the odor of the product, because the odor of different substances has a huge difference in the threshold of smell, which does not mean that the content is low and its odor perception is low. It can be considered to bake the parts in the later stage, which can effectively reduce the odor of the products.

No, it should just be able to isolate it.

A little better, completely solved the impossible.

The practical production experience of Halked vacuum technology shows. The selection of suitable vacuum pipelines is conducive to the normal operation of the vacuum extruder, and it is easy to obtain high-quality bricks and tiles. In general, the longer the vacuum line, the greater the resistance along the way and the local resistance, and the vacuum obtained by the vacuum extruder cannot be very high.

Therefore, the length of the vacuum pipeline should be shortened as much as possible, and it is best to install the vacuum pump next to the vacuum extruder or install it in the vacuum extruder (limited to small vacuum pumps), in order not to affect the operation, use and maintenance of the vacuum pump and the vacuum extruder as the principle, and according to the provisions of the vacuum pump, the pipe diameter of the vacuum pipeline should be selected as little as possible, and the curved pipeline, elbow and tee should be used as little as possible. Only in this way can the vacuum extruder be ensured to achieve a high vacuum level.

At present, the kiln types used in the sintered brick factory are mainly tunnel kiln and wheel kiln, and the operation process is also different for different kiln types. The following is introduced by the technician of Gongyi Wangda Machinery Factory to what processes are included in the vacuum extruder production line, and the bricks roasted by the wheel kiln? The roasting of bricks in the wheel kiln usually includes the main processes such as yard kiln (also known as kiln loading), roasting, and kiln exit, as well as auxiliary processes such as pasting the kiln door, opening (opening) the kiln door, pasting paper block, and cleaning the kiln road.

First, the yard kiln. The kiln operation includes transporting the bricks into the kiln and stacking them into a sparse and suitable form, correct form, horizontal and vertical, firm and stable according to the requirements of the roasting process. There is a saying in the brick and tile industry:

Seven points of yards, three points of firing", illustrates the importance of the yard kiln. The operation of the paper gluing block is also done by the yard kiln. 2. Roasting.

Roasting is the shutdown process of the wheel kiln to burn the bricks, which is completed by the kiln burner. This process includes three operations: watching the fire, using the brake, and adding coal. Kiln workers must control the fire in the kiln to ensure product quality.

3. Out of the kiln. Kiln removal is the process of removing the fired product from the stack and loading it out of the truck. If the brick factory does not set up a separate product selection personnel, in addition to unloading the finished product, this process also includes the inspection operation.

On the contrary, when burning bricks, it is generally required to set up a separate inspector. Due to the high temperature in the kiln and the large dust concentration, the working conditions of the kiln workers are relatively poor. Fourth, paste kiln door.

The paste kiln door is an important auxiliary process of wheel kiln roasting, and its operation is to close the kiln door filled with blank stacks. The tightness of the kiln door seriously affects the quality of the product. Fifth, the kiln door.

Open the kiln door, let the cold air into the kiln, and the billet stack begins to cool, this process is called the kiln door. Some factories arrange an auxiliary worker, working in three shifts, specializing in auxiliary operations such as pasting kiln doors, beating kiln doors, and cleaning kiln roads. 6. Clean up the kiln road.

After the finished product is out of the kiln, the process of removing the coal ash, cinder, brick and tile fragments left in the kiln road is called cleaning the kiln road. Workers who clean the kiln road must also regularly (once a week or once a half month) remove the ash and broken bricks and tiles in the Hafeng Tunnel, which is called digging Hafeng. Gongyi Wangda Machinery Factory is a manufacturer specializing in the production of tunnel kilns, wheel kilns and other complete sets of equipment, the main equipment is:

Vacuum extruder, automatic code blank machine, roller machine, automatic strip cutting machine, hammer crusher, rolling screen, ground crawler, hydraulic ferry traction top car machine, etc., the factory has been engaged in the production of brick and tile machinery for more than 40 years, the department's products have obtained national patent products, and passed 9000 certification, is the most ideal manufacturer for you to buy brick and tile machinery and equipment. Reference: Adopt it.

No. Unburned bricks Entry category: Building materials industrial supplies Introduction to unburned bricks:

A new type of wall material that uses fly ash, cinder, coal gangue, tailings slag, chemical slag or natural sand, mud mud, etc. (one or more of the above raw materials) as the main raw materials and is manufactured without high temperature calcination is called unburned brick. The product is in line with China's general policy of "protecting farmland, saving energy, adapting measures to local conditions, and using local materials", and is in line with the opinions of "strictly restricting the destruction of fields and burning bricks and actively promoting the reform of walls".

The unburned brick machine cannot be used for two purposes.

It is possible to make bricks, then you don't have to burn them, it is better to buy a machine specially used to make red bricks

There are many kinds of red brick clamping machines, some of which are directly clamped from the kiln car, some are forked from the bottom with a forklift after being packed, and some use aviation cranes, all of which are used with forklifts. There are also loading using the clamp of the whole row, I personally think that the investment is cheaper is to clamp a single row or multiple rows of machines, from the kiln car down directly loading, a clamp 20 40. There are also some kiln red bricks arranged neatly and are clamped very steadily.

The following is Guangsong trembling west of the dust brick machine, press 158 press 7811 press 9322, micro heart with the same number, plus look at the machine can clip hollow bricks, standard bricks, red brother royal bricks**, I don't have them to clip red bricks**, only this one found from the Internet, I hope to help you.

Fujian Guofa brick machine factory, 8-9 yuan each.

But first of all, pay attention to the following.

1. What is your vacuum level?

2. What is the air volume you want, that is, what is the pumping rate?

Through these air pumps, the manufacturer can choose the model for you.

You can call our free service**: 400 887 1011

We do Gaorui air ring real pump, German brand. Hope it helps. Thank you.

It depends on the vacuum degree you need, what is the pumping rate, find a vacuum pump manufacturer in the name of inquiry, let them give you a plan.

Choosing a plastic extruder vacuum pump can determine how much flow is required from the parameters of "vacuum, suction volume".

Hengyou has a vacuum pump unit dedicated to plastic extruders, which can use Atlas screw vacuum pumps;

Vacuum pump performance and lower energy consumption, judgment circle noise halved, performance doubled, maintenance halved, optimal oil and gas separation, greatly reduced footprint, simple and fast installation, saving installation space, all peripheral equipment in the overall package for customers to provide one-stop in place, plug and play.

1. Look at what products are produced.

2. Use. 3. What is the model of the extruder?
