What should I pay attention to in the laboratory decoration?
The laboratory decoration is similar to the ordinary decoration. The main area is the difference in materials and construction of water, electricity, wind and so on.
1. Waterway problem: The water used in the laboratory is generally: ordinary tap water, distilled water is triple distilled water, and ultrapure water is also ionized water. The construction of Sheung Shui should consider safety and science as well as application. When you go to the water, you need to choose materials according to the specific experiment, that is, the water pipe and the joint. Also consider the separation of water and electricity, the environment around the water pipe, the direction of the waterway and so on. The launching of the laboratory is generally more troublesome, because the requirements for the launching specifications of the laboratory and the actual national conditions, as well as the specific laboratory or laboratory building environment, are very different. The sewage in the laboratory can be roughly divided into: polluted water and low-polluted water. Low-polluted water generally refers to the condensed circulating water of some equipment and the wastewater from washing some containers. The range of contaminated water is many. Corrosive water, such as acid and alkali corrosion water, organic corrosion water, inorganic pollution water, and heavy metal pollution water, etc.
2. Circuit problem: Electricity use in the laboratory is a very important issue, weak electricity, lighting electricity, safety electricity and laboratory equipment electricity. Among them, the power consumption of laboratory instruments and equipment is the main focus, because laboratory instruments and equipment, especially some precision instruments, the principle of these instruments and equipment is mainly the role and reaction of the principle of Lorentz force, that is, through the slight change of current to control Changes in data. The problems we need to solve for the use of electricity in laboratory instruments are to control and reduce the current fluctuation, reduce or stabilize the value of harmonic changes, reduce or reduce the interference of magnetic fields, etc. If the problem of electricity cannot be solved, it will cause serious disasters, generally cause damage to the instrument, inaccurate or unstable experimental data, and reduce the service life of the instrument.
3. Exhaust system problems: Exhaust air in the laboratory is mainly to solve the needs of the safety of laboratory personnel and laboratory environment. The exhaust air of the laboratory mainly considers what environment needs positive pressure, negative pressure and constant pressure. The specific configuration depends on the specific nature of the laboratory, to arrange the size of positive and negative pressure. The exhaust air of the laboratory is not like the ordinary office air. It has very strict requirements for the air path and the direction of the gas. If the solution is not good, it will cause gas backflow and gas exhaust, or the exhaust volume is large. The odor still exists in the laboratory, and the effect of air exchange cannot be achieved. The specific nature of the laboratory is different, the required positive and negative pressures are different, and the air volume and the number of air changes are also different. The specific nature of the laboratory is different, and the relative and absolute wind exchanges to be achieved are also very different.
4. Finally, the selection of materials in the laboratory is also very important. According to different experimental properties, different materials should be selected to adapt to the special environment of the laboratory. Corrosion also depends on whether it is acidic, alkaline, or organic. Of course, we must also consider the high and low temperature environment of the laboratory. Some experimental areas may also consider the material deformation, aging, flame retardant, radiation and other conditions. Therefore, the selection of materials in the laboratory is more important.
