Product advantages:
The main problems affecting the service life of hydrogen production equipment are the shedding of cathode catalyst, the degradation of anode performance, and the decline of the hydrophilic and gas-repellent performance of the diaphragm. AUYAN's hydrogen production equipment has a unique life and durability strategy.
1. Avoid Cathode Catalyst Falling Off
"Pre-spraying technology" patent, the mechanical adhesion of Raney nickel on the surface of the nickel mesh is more reliable, and the service life is better guaranteed
2. Avoid anode performance degradation
Anode edge sealing adopts a "plate electrode" design to avoid local rapid oxidation deterioration and life decay of anode
3. Avoid the degradation of the hydrophilic and air-repellent properties of the separator
While the surface layer of the diaphragm itself is hydrophilically modified, an additional hydrophilic modification layer is introduced, so that the hydrophilic and air-repellent effect is strengthened inside and outside, and the overall hydrophilic and air-repellent performance of the diaphragm is lasting and stable.

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
Product Name:Aluminium sulphate Molecular Formula:AL2(SO4)3 Hs Code: 2833220000 CAS Code:10043-01-3 Standard:HG2225-2010 Shape:flake, powder, 2-4cm lump and 2-5mm/3-8mm granular Properties:There are two types,anhydrous aluminium sulphate and aluminium sulphate octadecahydrate.

Commodity: Synthetic Cryolite Formula: Na3AlF6 M.W.: 209.95 Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
