Titanium Dioxide(TIO2)
Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.

Shanghai Chongming County Environmental Protection Bureau This time, the Environmental Protection Bureau of Chongming County, Shanghai was on the "Chongming Island Eco-environmental Early Warning Monitoring and Evaluation System Environmental Protection Laboratory Testing Equipment (3)" and "Chongming Island Eco-environmental Early Warning Monitoring and Evaluation System Environmental Protection Experiment" The room inspection equipment (4) "purchasing project" was organized and purchased. The purchased equipment included GC-MS-MS, HPLC-MS, cold atomic absorption spectrometer, solid phase microextraction, TOC and other 54 sets, and the purchase amount was as high as 18.5 million yuan.
China National Environmental Monitoring Center Recently, the Chinese Government Procurement Network announced the results of the "National Environmental Monitoring Station Transformation Capacity Building Project (Phase II) laboratory equipment procurement project" winning results, this time the procurement of equipment including inductively coupled plasma mass spectrometry, atomic absorption spectrometry Photometer, automatic ambient air particulate sampling system (including PM10, PM2.5, PM1 cutter) 30 sets, the purchase amount of up to 14 million yuan.
On April 1st, Jiangsu Provincial Environmental Monitoring Center, Jiangsu Province Environmental Monitoring Center's South-to-North Water Diversion Monitoring Station and Instrument (JSZC-G2012-037) won the bid in the Chinese Government Procurement Online publicity. The winning candidate was the Shenzhen Langeshi Biological Instrument. The company, Nanjing Instrument and Meter Industry Supply and Marketing Company, Nanjing Jinghong Environmental Protection System Engineering Equipment Company, Beijing Haodeui Environmental Technology Company, Xiamen Longlide Environmental Technology Company, and Shanghai Zean Industrial Co., Ltd. have a purchase amount of 14 million yuan.
Environmental Protection Department of Ningxia Hui Autonomous Region Recently, the Environmental Protection Department of Ningxia Hui Autonomous Region on the “2011 Environmental Monitoring Station Standardization Construction Equipment and Equipment (excluding Vehicles) Procurement Project†and “2011 Central Fiscal Major Funding E The emergency incident monitoring project and the “Ningxia Radiant Environment Supervision Station Radiation Analysis Equipment Procurement Project†were purchased through open bidding. The procurement equipment includes GC-MS, gas chromatograph, graphite furnace/flame atomic absorption spectrophotometer, and vehicle/portable Fourier. Infrared multi-component gas analyzers, portable hazardous gas analyzers, etc. Nearly 100 sets/sets of environmental monitoring instruments.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
Tens of millions of equipment purchases from environmental protection agencies increased
From March 26 to April 1, in just 7 days, China Government Procurement Network successively announced a number of environmental protection monitoring equipment bid/bid large orders. The procurement units include Shanghai Chongming County Environmental Protection Bureau, China Environmental Monitoring Center, Jiangsu The Provincial Environmental Monitoring Center and the Environmental Protection Department of Ningxia Hui Autonomous Region have 4 units, and the total purchase amount is expected to exceed 50 million yuan. It can be seen that, in recent years, China has continuously increased investment in environmental monitoring and monitoring, and the market demand for environmental monitoring instruments has grown rapidly.
