Factories Close in A Large Area Cause Environmental Inspection
June 18, 2018
More and more stringent environmental inspection in China Environmental factors are playing big influence these days. Last week, inspection of environmental protection in Jiangsu province continued, except Xuzhou, Nanjing, and Changzhou, Zhangjiagang, the production in Wuxi, Suzhou and other regions has also been affected by environmental protection policies, and production has declined. Last week, steel prices continued to rise in China, especially for construction steel prices. The steel market has become increasingly dangerous. It needs to pay attention to risks and we can’t just chase them. Factories are facing unprecedented challenges As all our steel suppliers close last week for inspection, steel price had a sudden increase this week, rate can be 10%. The bigger problem is that we can not buy new steel, so now we can only supply our stock which is mainly the specification below FS1250. For details, pls contact our sales. For raised floor factories, more
The Advantages of Calcium Sulphate Raised Floor
April 14, 2018
Since 1990s, calcium sulphate raised floor has been widely used in European countries. These years, China ’s awareness of environmental protection, energy conservation and recycling has increased. The market share of calcium sulphate raised floor has increased dramatically at the same time because of the advantages of the floor. Production process of calcium sulphate floor The raw materials of calcium sulphate floor are mainly natural gypsum powder(CaSO4 1/2 H2O) and reinforced fiber (primary and secondary fibers), they occupy more than 85% of a calcium sulphate board. Together with other materials such as mineral binder, water, they are mixed and pressed through high voltage. Then the installer should maintain the calcium sulphate board in thermostatic room for around half a month. And should keep it until the bending strength of board can reach 12-15 Mpa. The advantages of calcium sulphate floor Environment friendly & recyclable The content of gypsum powder and
How to Avoid The Crackling Sound of Steel Raised Floor
April 7, 2018
After installing steel cementitious raised floor, some customers will feedback that when people start to walk on them, sometimes noise problem(crackling sound) happen. Why crackling sound happen This situation only occurs on steel cementitious raised floor with bare finish, and it is mainly concentrated on raised floor with concentrated load less than 350KG. Steel cementitious raised floor is composed of two layers of steel plate and cement. When the cement is dry, if there is pressure on raised floor, the cement will break, this is the source of broken sounds. In our experiments, when there is only cement without steel, the cement breaks when the limit deflection reaches 0.8mm. But even when the deflection reaches 5.0mm (the deflection of the CISCA test standard is 2.5mm), whole steel cementitious raised floor will not break. Raised floor with concentrated load less than 350KG is light-grade level. When there is pressure on this
Why Data Center Need Hot-dip Galvanizing Pedestal & Stringer
March 21, 2018
As we introduced the differences between hot-dip galvanizing & zinc galvanizing, then which one should be used for your projects, and why you need to choose that. Where zinc galvanizing pedestal & stringer suit In office buildings and commercial buildings, zinc galvanizing pedestal and stringer are used much more than hot-dip galvanizing pedestal and stringer. The stability of zinc galvanizing is worse than hot-dip galvanizing, zinc galvanizing may start to fall off after several weeks while hot-dip galvanizing can remain stable for several years, but price of hot-dip galvanizing can be around five times higher than zinc galvanizing(price in 2016). Taking economic factor into account, zinc galvanizing pedestals and stringers would be the better choice. Where hot-dip galvanizing pedestal & stringer suit In a high-grade data center or clean room, hot-dip galvanizing pedestal & stringer would be very necessary. If zinc galvanizing pedestal & stringer are used, when galvanizing start
Differences Between Hot-dip Galvanizing & Zinc Galvanizing
March 20, 2018
Hot-dip galvanizing and zinc galvanizing are both effective methods of metal preservation, they are widely used in the production of raised floor accessories like pedestals, stringers. Difference in principle Hot-dip galvanizing is a chemical treatment that belongs to the electrochemical reaction. Zinc ingot is melted at a high temperature, with some auxiliary materials inserted. Then metal structures are immersed in a galvanizing bath so that a zinc layer is attached to them. Zinc galvanizing refers to electroplating, it is a physical process. Zinc salt solution is electrolyzed, so that a zinc layer is attached to metal structures. Difference in parameter After the process of hot-dip galvanizing is completed, when steel thickness is not less than 5mm, the average zinc layer weight is not less than 610g/sqm; when steel thickness is less than 5mm, the average zinc layer weight is not less than 460g/sqm. Zinc layer thickness of zinc galvanizing is

How to Prevent Static Electricity
March 15, 2018
We have already introduced the harm of static electricity, so what can we do to prevent and reduce static electricity? Using anti-static raised floor Almost all data centers, computer rooms and places with a large number of electronic components will use anti-static raised floor. Anti-static raised floor can control the resistance between raised floor surface and ground within of 1×105Ω to 1×108Ω, so that raised floor surface has the function of conducting static electricity. Even if the computer or the human body is charged with static electricity, it can be quickly leaked through raised floor to the ground. Grounding Grounding refers to connecting a metal conductor to the ground electrically, so electric potential of metal conductor and the ground can be close. Grounding is the most basic measure to prevent static electricity, it aims to form an electrical leak circuit between metal conductor and the ground so static electricity
How Static Electricity is Generated
February 15, 2018
Anti-static technology is part of the protection of the data centers, serve rooms, computer rooms, etc. Static electricity is one of the most frequent and most difficult harm to eliminate, it will not only cause random failures in the operation of electronic elements, but also cause the breakdown and destruction of certain components, such as CMOS, MOS circuits, and dual-level circuits. In addition, it will also harm physical and mental health of operators. How static electricity is generated The generation of static electricity is mainly caused by friction, contact and separation between objects. There are other reasons, in the process of static electricity generated by an object, because there is still a part of the charge that does not disappear and exist in the object, the object is called “electrostatic charged object.” The harm of static electricity Electrostatic discharge can form a fire source and cause fire. From the body
Why Laminate Cracks And How to Avoid It
February 1, 2018
Many users of anti-static raised floor reached us and asked about cracking problems in the anti-static flooring (mainly laminate HPL). Some raised floors even have just been used for one year. This not only affects the aesthetics of the entire room seriously, but also has an adverse effect on the anti static performance of HPL, the devices may fail due to the inability to release the static electricity. What should we do in this situation? Why laminate cracks? The main reason for HPL laminate cracking is due to that the temperature and humidity of the environment exceeds the design standards of the HPL. In a very cold or hot place, a huge change in temperature will cause the expansion and contraction of anti static flooring. Because the physical properties of HPL are hard, expansion and contraction above a certain limit can lead to cracking. In the data center and computer
