NaY molecular sieve production technology through identification

Recently, the China Non-ferrous Metals Industry Association hosted the scientific and technological achievements appraisal meeting of “NaY Molecular Sieve Production Technology” undertaken by Shandong Aluminum Co., Ltd. in Zibo City, Shandong Province. The appraisal committee heard the project's research report, reviewed the relevant appraisal materials, visited the site, and after questioning and discussion, experts believed that the NaY molecular sieve production technology has achieved industrial applications and has the following technical features and innovations: 1. The process materials From the alumina plant, the crystallization mother liquor is used to produce 4A zeolite and X zeolite, eliminates the discharge of waste liquid and waste residue, reduces the production cost of NaY molecular sieve, and meets the environmental protection requirements; 2. The full use of crystallization mother liquor , Do not return to the batching system, greatly shortening the crystallization time; 3. Excellent product quality: crystallinity ≥ 90%, silicon-aluminum ratio ≥ 5.3. 4. The use of advanced synthesis tank, large volume, high mixing speed, improve production efficiency .

The project has been applied to production, the technology is reasonable, the product quality is stable, and it has received good economic and social benefits. Experts believe that the overall technology of the project has reached the leading domestic level and has a good promotion prospect.

Eps Sandwich Panel

What are the characteristics of EPS Sandwich Panel ? What are the advantages of using it?
EPS sandwich panel are used in many buildings. The advantages of using this type of panels are obvious, and the price is also very favorable. There are many simple Prefabricated K House and Steel Structure Warehouse that use this type of board, so what are the advantages of its use?

low thermal conductivity
Because the thermal conductivity of EPS itself is relatively low, its effect as an insulation material is also very good, it can ensure the indoor temperature, and can also achieve a good energy-saving and environmental protection effect. It is precisely because of its good thermal insulation ability that under the same thermal insulation requirements, it can effectively reduce the thickness of the outer wall of the building and increase the internal usable area.

Good moisture-proof effect
Because the closed cell rate of the EPS sandwich panel reaches more than 95%, it is a kind of hydrophobic material, so there will be no moisture, and there will be no water seepage on the wall, which can ensure the reliability of the long-term use of the panel. . The Rock Wool Sandwich Panel is more susceptible to moisture.

Fire retardant effect
This type of material is resistant to high temperatures and also has very good fire resistance. Fire rating B1. And after a certain amount of flame retardant is added to its material, even if a fire occurs, it can also avoid natural disasters. Decomposition will only occur when encountering high temperature, and a carbonized layer is formed on the surface, and the safety of long-term use is also guaranteed.

strong security
The EPS sandwich panel has strong anti-deformation ability, and it will not be deformed or cracked after long-term use. Moreover, its installation stability is guaranteed, there will be no problems such as falling off, and the safety of long-term use is also guaranteed.

good sound insulation
Because the structure of this kind of board is stable and basically closed-cell, it can not only keep warm and waterproof, but also has a good sound absorption effect, and the sound insulation effect is also guaranteed.

Price concessions
Compared with other boards, EPS sandwich boards are cheaper in price and have a variety of properties, which is also very good in terms of cost performance. Therefore, if you want to ensure that the construction cost is favorable, then this type of sandwich panel is also very worthy of our choice, which can save a lot of construction costs.
