Market Analysis: Demand for international construction and construction building materials market surges
The development of the global construction market has led to a surge in market demand for concrete products, concrete pipe shafts and prefabricated components. The above requirements have promoted the production of building materials for the above products. "Target=_blank>In the building materials and equipment industry, the field of concrete block production machines and systems for concrete prefabricated components will grow. The German Machinery Manufacturers Association expects that building materials" target= _blank>Building equipment and construction machinery sales in 2012 will achieve a 5% growth rate.
The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings are available as full complement (no cage) or with cages made from PTFE, PEEK or 316 stainless steel.
These are non magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial clearance for full ceramic bearings is C0 but other clearances can be supplied to order.
ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.
The Description of Ceramic Bearings:
Potential demand in emerging markets
The international market has also developed. Recently, the Institute for Applied Research (IAB–InstitutfürAngewandte Bauforschung) in Weimar conducted a questionnaire survey on some German building materials “target=_blank> building materials equipment manufacturers. According to the results of the survey, relevant markets, especially global market sales. Expected to achieve growth. The Institute pointed out that demand from emerging markets (including China, India, some Eastern European countries and some member countries of the former Soviet republics) is particularly strong. The above survey report shows that production monitoring systems are receiving much attention, and Production monitoring system manufacturing technology and services also have strong market demand.
Concrete prefabricated components from India and Singapore
VollertAnlagenbau from Weinsberg announced that the company has released India's first pallet circuit system. Currently, the system is used in the construction company PrecastIndiaInfrastructures in the western Indian city of Pune. The plant produces 120 square meters of concrete prefabricated walls, concrete prefabricated floors and hollow slabs per hour, mainly serving the booming construction of the Indian subcontinent.
Another example of the “Made in Germany†technology transplant overseas is Singapore's first fully automated concrete prefabricated component factory. The plant was officially put into operation in May 2012. In the fast-growing economic environment of Singapore, demand in the residential and industrial construction sectors has increased, and this system is well positioned to meet the needs of these areas. VollertAnlagenbau and WeckenmannAnlagentechnik from Dormergengen jointly released an important part of the system.
Ukraine improves production of aerated concrete
The Ukrainian aerated concrete plant, which was completed in March this year, is a typical project in the former Soviet Union. System manufacturer MasaofPortaWestfalica increased the daily production of the Dnepropetrovsk plant from the previous 1,000 cubic meters to 1,400 cubic meters.
Good prospects for plastic concrete
In terms of new technologies, IAB's research report shows that the market's attention to the plastic concrete production process has generally increased. Plastic concrete is used in a large number of flexible special molds with an inner surface pattern. The surface of the concrete will retain this pattern after processing is completed. These technologies can help companies produce high quality products with a unique look.

Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.
Firstly, they can be used in corrosive environments. Compared to stainless steel bearings, hybrid and all Ceramic Bearing lasted three and twenty times longer respectively. It is presumed that water readily adheres to silicon nitride and forms a better lubrication film, leading to extended bearing life.
Secondly, they can be performed in corrosive agents. Generally, silicon nitride has excellent corrosion resistance. However, corrosion resistance varies depending on the type and quantity of sintering additives, and certain corrosive agents decrease in hardness and flexural strength. In such situation, it is can be proved that the carbide-based ceramic bearings are the most effective.
Thirdly, they can be used in high-temperature vacuum. An all-silicon nitride Ball Bearing with a self-lubricating laminated cage (mainly composed of MoS2) and with MoS2-coated rings and balls proved superior in durability in a high-temperature vacuum environment. Compared with the hybrid bearings, the all-ceramic bearing was superior in both dynamic frictional torque and life.
Fourthly, they can be performed with poor lubrication. As ceramics are extremely hard and have outstanding wear resistance, they outperform other materials in bearing life without lubrication. According to a test, the steel bearing seized within a short period while the hybrid and all 627 Ceramic Bearings, though sustaining wear, did not. And the all-ceramic bearing sustained considerably less wear than the hybrid bearing, indicating that its endurance life is much longer.
