Why Anti-static Accident Happen in The Factory
November 8, 2018
Many factories use a lot of anti-static products to prevent static accident. However, why do static damage often occur? Here are the reasons. No anti-static product testing equipment The most common mistake is that many companies purchase a lot of anti-static products. However, they do not have some commonly used anti-static product testing equipment. We know that each product has a certain period of use, and the quality is good or bad. Without some commonly used testing equipment, we do not know whether the product is damaged and whether the quality is good. In this way, there is no anti-static effect. Use anti-static products as ordinary products Many companies use anti-static products as ordinary products. And they think that they can continue to be used without deformation or cracking. In fact, this is a misunderstanding. Anti-static shoes without anti-static clothes In addition to wearing anti-static shoes, people must wear anti-static
How to Choose The Right Anti-static Raised Floor You Demand
October 10, 2018
When we buy anti-static raised flooring, they will always encounter some problems, such as poor quality, deterioration, deformation, or a series of situations beyond their own budget. So what kind of work do we need to do before we buy the right raised floor? First, calculate the size of the floor and the area of the house. When purchasing, try to exceed the area. Leave some margin to avoid shortages, but do not overdo it and waste. Second, know the manufacturer in advance. Select the manufacturer and then conduct some research on its products, mainly to look at some performance indicators, two aspects, one is mechanical performance, another is electrical performance. Mechanical properties are mainly bearing capacity and abrasion resistant. Electrical performance is mainly about system resistance and surface resistance. Third, look at the weight of the heaviest mechanical equipment in your computer room, and then determine the load on the anti-static floor. This will prevent
Calcium Sulphate Raised Flooring VS Steel Raised Flooring
September 12, 2018
There are many differences between Steel and Calcium Sulphate Raised Flooring. We will analyze from the following points and let’s take a look. Characteristics of calcium sulphate raised flooring and steel raised floor Structure Steel raised floor is made of good quality cold rolled steel sheet, which is stretched, spot welded, and coated with epoxy powder after having been phosphated. There is foaming cement fully filled, with corner-lock holes pouched in four sides of panel. Calcium sulphate panel is made of high strength calcium sulphate core. The top surface can be stuck with all kinds of covering, the bottom can be covered with aluminum foil or galvanized steel sheet. Four edges are sealed with PVC edge trim. Fire Resistance Calcium sulphate raised floor shows the best fire resistance in a variety of raised floors, so it offers the most valuable solution for safety. Steel raised floor is also fireproof, but
How to Distinguish A Good-quality Calcium Sulfate Board
July 19, 2018
In China, the concept of calcium sulfate raised floor take domination. Market understands few about calcium sulfate raised floor. Due to the advantages of calcium sulfate raised floor (such as recyclability, excellent fire performance, excellent acoustic performance, etc.), more and more people choose calcium sulfate raised floor. Then more factories produce calcium sulfate raised floor. However, most calcium sulfate raised floor produced in China are not real and pure. How to distinguish good quality calcium sulfate boards? The report of calcium sulfate board factories in China Here we are talking about calcium sulfate board, not finished calcium sulfate raised floor. Only with a good-quality calcium sulfate board can the following production process make sense. The calcium sulfate floor is derived from Knauf in Germany. In addition to the Chinese factories, companies that produce calcium sulfate board in the world now include “Knauf” and “Lindner”. In China, there are more than
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
