Aluminium Polychlorid
Aluminium Polychlorid ( PAC)
1. Product information
Product Name: Aluminium Polychlorid ( PAC)
Molecular Formula: Al2Cln(OH)6-n
Molecular Weight: 174.45
Melting Point: 174.45
Appearance: yellow and brown powder
2. Properties
It has the properties of adsorption, condensation, precipitation and corrosiveness
3. Packing
25kg PP/PE bag or by request of clients.
4. Transport storage
When transported, it should be in a clean, clean, covered wagon or boat.
Should be stored in a dry, clean, ventilated warehouse, not in the open air.
5. Feature
(1) PAC polymerized
aluminum chloride has the advantages of good spray drying stability, wide water
area, fast hydrolysis speed, strong adsorption capacity, large alum flowers,
rapid mass density precipitation, low water turbidity and good dehydration
performance.
(2) In the case of the same water quality, the addition
amount of spray drying polyaluminum chloride is reduced. Especially in the case
of bad water quality, the amount of spray drying products can be reduced by
half compared with that of roller drying polyaluminum chloride, which not only
reduces the labor intensity of workers, but more importantly reduces the water
production cost of users
(3) In addition, spray drying products can guarantee
safety, reduce water accidents, and be very safe and reliable for drinking
water of residents.
6. 3 Color Types
♦White Poly Aluminium Chloride
Compared with
his polyaluminium chloride is of the highest quality products, the main raw
material is high quality aluminum hydroxide powder, hydrochloric acid, the
production process is the most advanced technology of spray drying method.
Polyaluminium chloride is used for paper sizing agent, white sugar decoloring
clarificant, tanning, medicine, cosmetics, precision casting and water
treatment and other fields.
♦Yellow Poly Aluminium Chloride
Raw materials
is calcium aluminate powder yellow polyaluminium chloride, hydrochloric acid,
bauxite, mainly used for sewage disposal and drinking water treatment, raw
materials are used for water treatment aluminium hydroxide powder, hydrochloric
acid, and a few calcium aluminate powder, the process is the plate and frame
filter or spray drying process.
Yellow polyaluminium chloride general drum drying or spray drying tower
production and become, flake, powder machine has two solid form.
♦Brown Poly Aluminium Chloride
Brown is the
raw material of polyaluminium chloride calcium aluminate powder, hydrochloric
acid, bauxite, iron powder.
Production technology is using the drum drying method, generally is mainly used
in sewage treatment, because it added iron powder and brown in colour, iron
powder added the deeper the color, the more iron powder if over a certain
amount of iron in some cases, also known as polyaluminium chloride, has good
effect in increase in sewage treatment.
