Ceramic performance and classification

1, what is the ceramic
As the name implies, is a pottery ceramic particles. Exterior features ceramisite most were round or oval-shaped ball, but there are some imitation stone ceramic ball is not round or oval, and irregularly shaped gravel. Ceramic shapes vary from process to process. Its surface is a layer of hard shell, this crust was ceramic or enamel, with a gas impermeable security role, and give high strength ceramic. Color due to the appearance of ceramic raw materials and processes used in different different. Firing ceramic colors are mostly dark red, red ocher, there are some special varieties as a pale yellow, gray and black, gray, blue gray, etc.
ceramic proppant is a granular product with high fracturing intensity, mainly for oil well supported in order to increase oil and gas production, an environmentally friendly product. This item is the use of various raw materials such as high alumina, sintered ceramic, a natural quartz sand, glass beads, metal balls, low intensity  Proppant  substitute for oil and gas production with good results. Oil and gas deep mining, the high closure pressure low permeability deposits by fracturing treatment, the rock cracked hydrocarbon, oil and gas from the cracks formed in the channel pooling out. Ceramic support material with a solution into the formation along with the high-pressure filling fissures in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that gas flow, increase production. Practice has proved that using ceramic proppant fracturing wells can increase production by 30-50%, but also to extend the service life of oil and gas wells.
Fracturing proppant can be widely used in deep, high pressure oil layer fracturing. High quality bauxite as raw material by the king to be finely ground into powder after crushing, with various additives, repeated mixing, granulating and polishing. High temperature sintering, the product has high strength, low density, good sphericity, finish high flow capacity and other advantages. The China Petroleum Exploration and Development Research Institute, Langfang Branch support evaluation laboratory testing, the performance indicators fully meet SY/T5108-2006, SY/T6302-1997 standards, currently in the lead.
2, the performance of ceramic
The reason why ceramic rapid development in the world, because it has other materials do not have many of the excellent performance of this excellent performance, it has the excellent performance of this material can not be replaced by other effects. These excellent performance in the following aspects.
The bulk density of the ceramic itself is less than 1100kg/m3, is generally 300 ~ 900kg/m3. In the production of ceramic concrete as aggregate density of 1100 ~ 1800kg/m3, corresponding concrete compressive strength of 30.5 ~ 40.0Mpa. The most important feature is the appearance of ceramic hard, but there are many within the pores. These pore-ceramic lightweight properties. 200 Lytag concrete density is 1600kg/m3, while the same label ordinary concrete density is as high as 2600kg/m3, a difference of 1000kg/m3.
