Applications:

 

1. Characteristic requirements for titanium dioxide in coatings and paints

Coatings industry consumes most qty of titanium dioxide, especially the rutile type. The global coating industries occupy 58% - 60%, mainly because the aspects of the performance is much better than the other white pigments. So the coating using by titanium dioxide is much higher than ordinary filler, because titanium dioxide is an integral part of in the coating, covering and adornment, its role is not only more important is to improve the physical and chemical properties of paint, bust also to improve the mechanical strength of the coating, adhesion, anticorrosive, light and weather resistance.So during of the production of coatings, It’s reasonable for us to choose the suitable type and specs!

 

2. Titanium dioxide quality requirements for plastic, PVC and masterbatch

 

Item	Performance
Hiding power	Lighter and thinner plastic products can be produced using tio2 of good hidinding power
Whiteness	Decide the appearance of the white or light color palstic products light color or white color
Dispersibility	Affect the production cost of plastic products as bad dispersibility affects the  smoothness and brightness
Weather resistance	The outdoors plastic products and plastic doors and windows require the weather resistance of tio2
Machinability	Titanium dioxide machinability is the vital key to the production efficiency and cost in the production of white masterbatch (especially the concentration variety)
Performace impact	Titanium dioxide volume of addition can affects the quality of the plastic products, especially in the condition of larger addition

Plastic is the second largest parts for titanium dioxide, occupying about 20% of the total world titanium dioxide demands, There are more than 50 brands belongs to plastic specials in the world 500 barands. Requirements for plastic, fine particle, good dispersion performance;Good heat resistance and light resistance,During the heat and the plastic forming process , the finished product does not change color in sunlight exposure and use process. Most of the particle size in plastic is fine. In the plastics, to join titanium dioxide

can improve the heat resistance of plastic products, light fastness, weather resistance, make the plastic products to improve the physical and chemical performance.The strong mechanical strength can extend their life!

The effect of titanium pigment in the plastics industry mainly has two aspects, one is used as the basic white pigment, provide cover (white color); the second is to block uv light, used as uv screen disadvantages agent, used for outdoor plastic products to provide a good weatherability. For the Common plastic,it does not require the weatherability, focuses More on the paint performance requirements.

Due to the characteristics of palstic products, When choosing different, should be taken into account in accordance with the technical requirements of plastic products, mainly to choose anatase or rutile, not same as the coatings, inks, paints.

 

 

Description:

 

1. Liangjiang brand-Rutile titanium dioxide pigment R628 is coated with zirconia and alumina in an inorganic manner and modified with special organic finishing agent on the surface. As a kind of multifunctional and general-purpose rutile TiO₂ pigment with excellent whiteness, dispersibility, hydrophilicity and lipophilicity, it can be applied to a lot of fields including coating, plastic, ink and paper.

 

Main features:

 

excellent whiteness, reducing power and covering power. Good dispersibility in both aqueous and oiliness system; it also has superior weather fastness, heat resistance and light resistance. It can be widely used in many fields.

 

Applied range:

 

 R-628 is top grade, universal type rutile grade titanium dioxide. It is widely used in kinds of decorative paints ( outdoor and indoor ), powder coatings, coil coatings, universal industrial paints ( plastic, ink, paper, rubber, leather etc ) .

 

2. Comparation of chlorination process VS. Sulfuric acid process rutile titanium dioxide produced by Liangjiang:

 

 

 

 

 

 

3. Titanium dioxide compared with other kinds of white pigment :

 

From this sheet, Liangjiang brand rutile titanium dioxide, chlorination process and sulfuric acid process, both has highest coefficient of refraction, highest covering power and tint reducing power. Higher whiteness, higher gloss and better dispersibility.

4. Titanium dioxide anatase, titanium dioxide antase coated, titanium dioxide rutile sulfuric process, titanium dioxide rutile chlorination process:

 

Coatings industry consumes most qty of titanium dioxide, especially the rutile type. The global coating industries occupy 58% - 60%, mainly because the aspects of the performance is much better than the other white pigments. So the coating using by titanium dioxide is much higher than ordinary filler, because titanium dioxide is an integral part of in the coating, covering and adornment, its role is not only more important is to improve the physical and chemical properties of paint, bust also to improve the mechanical strength of the coating, adhesion, anticorrosive, light and weather resistance.So during of the production of coatings, It’s reasonable for us to choose the suitable type and specs!
