How is titanium dioxide dispersed in the aqueous phase?


Basic principle of dispersion of titanium dioxide in aqueous phase

We can roughly divide the grinding and dispersing process of titanium dioxide into three steps of mutual influence and mutual restraint: (1) wetting; (2) separation; and (3) stabilization.

In the actual grinding and dispersing process, these three steps are not gradual, but a ring and a ring, complement each other and mutually restrict each other, that if one of the three can not achieve the purpose, the grinding efficiency will be reduced or even the product can not be reached. The degree of demand, or rough.

There are roughly the following types of pigment dispersion stabilization mechanisms:

1. Electric double layer stability theory;

2. Space stability theory;

3. The theory of vacancy stability;

4. The above various stabilization mechanisms are combined with each other.

The double-layer stability mechanism is widely used in various application systems. It is the most classic and most reliable theoretical basis, and has a very good applicability for pure aqueous phase systems. The theory of space stability and the theory of vacancy stability involve the role of high polymers, which is relatively complicated. However, when organic treatment of rutile titanium dioxide, how to choose a suitable organic treatment agent, how to control the appropriate amount of addition, It has a good guiding significance.

This classification including seamless Square Steel Tube, seamless Rectangular Steel Tube and seamless circular Steel Tube, usually they are used for contruction purpose, also some customer use them for car , billbord, stents, fence etc.

Jinan Xin Jiyuan Special Section Tube Co., Ltd. is the holding company of Jinan Xin Fangyuan Special steel tube Co., Ltd. founded in 1997. Our companies located in Dawei Industrial park, north end of Second Ring Road, Jinan City, Shandong Province, closed to Beijing-Shanghai expressway exit, transportation is very convenient, and also have a good production and operation environment.

Our company purchased three production lines at the cost of over 16 million for expansion of the new factory; they have been gradually put into operation. These production lines make full-sizes of square tubes and rectangular tubes: 20x20 -600x600 square tubes, 20x30 - 400x800 rectangular tubes, Thickness: 1.5mm to 32mm, over 2800 kinds of specifications, Material: Q195, Q215, Q235, Q275, Q345, 20#, 45#, stainless steel, seamless pipe, alloy steel etc. We could produce diamond, triangular, pentagonal, hexagonal, fan etc. special sizes, also could tailor-made according to customer drawing and dimension.

Our products of large-diameter, thick-walled square or rectangular tubes fill the part blank of domestic and abroad market. Our products are widely used in large scale steel structure engineering, machinery manufacturing, shipbuilding, bridges, construction industry, metallurgical industry, automotive industry, railways, highways, aviation, container, furniture, decoration and many industries. The company regards product quality as the lifeblood of the enterprise; use personality makes products, layers the guarantee the quality of products. Our company has passed ISO9001:2015 quality management system certification, products passed Europe Union 10210-1:2006, 10219-1:2006 CE certification and FPC issued by Lloyd. Company with more variety, large inventory, high quality, low price, short delivery time and good after-sales service, and many other competitive advantages, has become designated supplier of many large enterprises. Customers throughout our country in more than 20 provinces and cities and exported to the United States, Canada, Russia, India, Malaysia, Europe and other countries and regions.

This production line is the international leader and the first domestic gradual roll extrusion mill group, it abandoned the original workshop mode of cold drawn square steel tube, the small workshop mode have disadvantage of production slow, No quality assurance, twist, bend crack, uneven thickness, and the same time abandoned now widely used in cold unit lines, large quantity, low accuracy, single size, small caliber, thin (15.75mm) and other defects. The unit for forming, straightening one unit, the entire computer monitor, no need to manually pull hard. Fully automated units could ensure mechanical and physical properties of square tube and rectangular tubes. The hourly output of each production line more than 20 tons, all annual output up to 1.5 million tons.

Our chairman and general manager Changxing Hu, heartfelt thanks friends from all walks of life for many years trust and support, our all staff service to our clients as usual, and common development, win-win cooperation, good faith altogether casts and create brilliant.
