Description:

 

1. Sulfuric acid process titanium dioxide

 

Advantages: use cheap titanium ore (or titanium slag) and sulfuric acid as the main raw materials, of long-history technology, proven technique and low production cost.

 

Disadvantages: process, long process, serious pollution to the environment, low product quality stability

 

2. Chlorination process

 

Advantages: using the less impurities artificial rutile of 90% tio2 purity as the raw material, short process flow, production capacity easy to expand and continue, high quality.

 

Disadvantages: because of the monopoly of the foreign companies, it’s hard to bring in the foreign technology and equipment in China. Besides, due to the raw material of high content titanium dioxide ore, the production cost is relatively high and the process is hard.

Due to the different raw materials and production process, the product performance is different and has different requirements to the weather resistance, hiding power, aesthetics and dispersion titanium dioxide. So the clients should choose titanium dioxide of different quality based on their needs.

Applications:

 

 

1. Characteristic requirements for titanium dioxide in coatings and paints

 

Item	Building Coat
	Normal temperature drying enamel paint (Little porcelain paint type)	emulsion coatings
Outdoor	weather resistance, Hiding power, aesthetic property	weather resistance, Hiding power, aesthetic property( Little outdoor)
Indoor	Hiding power, aesthetic property	Hiding power, aesthetic property
Item	Industrial Coat
	automobile	home electrical appliances
Finish coat	weather resistance, Hiding power, aesthetic property , dispersibility	Hiding power, aesthetic property
floating coat	weather resistance, Hiding power, dispersibility
primer coat	dispersibility

 

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 ink :

 

Titanium dioxide , also have a wide range of applications in ink,rubber and others, including the three major application fields.

 

 (1) Ink

 

Titanium dioxide is an indispensable white pigment in the senior ink, ink containing titanium dioxide color fast, good surface moisture resistant, easy to disperse, rutile type titanium pigment,both used in the printing ink industry .
Practice proved rutile type titanium pigment has ideal application performance, can be widely used in various types of ink preparation, crystal shape, refractive index and tinting strength, the index of fluorescence, type is better than the sharp titanium rutile type titanium pigment, therefore, rutile type titanium pigment is widely used in printing ink.

 

 

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

 

	Titanium dioxide anatase	Titanium dioxide antas   e coated	titanium dioxide rutile sulfuric process	titanium dioxide rutile chlorination process
Powder type	Indoor powder	Indoor powder	Indoor /outdoor powder	Indoor /outdoor powder
Usage amount	big	seldom	big	little
