White polymerization by aluminum hydroxide powder and alcl3 high-purity hydrochloric acid spray drying and processed by a white or ivory milk powder form fine powders, bare in air easily melt. Say again: spray drying polymerization is concerned, it with ordinary poly aluminum compared with the following characteristics:
A, AL2O3 content high, 29.5%.
Secondly, salt base, low intensity, and ordinary gather only 50% of aluminium salt base degrees is 90%
Thirdly, water insoluble, small, only 0.3%, while ordinary poly aluminum has more than 2%.
Four, colour is pure, the productization after water solution and limpid, without any color, while ordinary poly aluminum aqueous color yellow or brown.
Product use
1, mainly used for domestic and drinking water, industrial water supply, oilfield waterflooding, cooling water circulation and back to various sewage (such as municipal sewage, oily wastewater, printing and dyeing wastewater, sewage, papermaking wastewater treatment of steel mill etc) processing.
2, the papermaking glue precipitation agent, sugar decoloring clarify agent.
3, used for tanning, pharmaceutical, cosmetic and precision casting, and other fields.
In recent years, white polymerization has replaced vitriolic aluminium as papermaking industry of neutral glue precipitation agent, compared with vitriolic aluminium, white polymerization has the following features:
1) large has positive charge, shape more stable nuclear hydroxyl aluminium complex, can effectively promote flocculation and glue.
2) appearance white, iron content is extremely low, can satisfy the need of manufacturing quality paper.
3) polymerization of aluminium alcl3 is beforehand hydrolysis thing, hydrolysis degree relatively low, pulp pH declines than vitriolic small.
4) vitriolic only suitable for acid glue, and polymerization alcl3 acidic and neutral environment glue, the system of corrosion weakened dramatically, the white water treratment of easier.
5) can be added a fill of cheap calcium carbonate packing, not only reduces the production cost, improve the paper to whiteness and flod-resistance sex, also overcome the synthetic rubber materials (such as AKD etc) unavoidable disadvantages (such as skid, sizing degrees is difficult to control, etc.).
6) using aggregate alcl3 glue, the paste retention aid and help filter function improved significantly.
7) paper properties except crack continue long outside, other each index all different degree to improve.
Method of use will solid product made into content for 10% of liquid products, spend glue filler adding 1.5-3.0% liquid products and stir with the paste mix adequately can. Its usage and dosage of alumina, as is only one-third of alumina, press despiseth dry paper calculated dosage is 2% - 3%.
Packaging and protective this product USES double packing, inside outside using plastic bags, topical packaging. Each pack 25 kg.
Note:
1, this product belongs to slant acid product, absolutely forbidden with alkaline substances (e.g., bleaching water, such as lime), otherwise the product will be deposited with failure.
2, solid product easily absorbing moisture, should be placed in dry place to store.
3, in bags intact cases, shelf life for a year.
