How to choose the experimental table in the physics laboratory?

Compared with the chemical laboratory, the experimental bench of the physics laboratory has almost no requirements for corrosion resistance, the optical laboratory requires the Xige laboratory to have high levelness and good seismic resistance, the mechanical laboratory requires the experimental bench to be impact-resistant, wear-resistant and load-bearing coefficient, and some physical experiments require the laboratory bench to be anti-static.

1. Solid core physical and chemical plate.

Ordinary physics laboratory benches without special requirements can use solid core physical and chemical boards as countertops, but pay attention to maintenance, and can not use sharp objects to scratch, melamine plates can also be used as the countertops of ordinary physics laboratory benches.

2. Stone countertop.

For some physical experiments with high temperature, high pressure and high wear, the physical experiment table of stone has advantages, such as granite and marble, which not only has high temperature resistance, good bearing capacity, but also strong impact resistance compared with physical and chemical boards.

3. Stainless steel countertop.

Stainless steel countertops can be used for the manufacture of countertops of optical tables, in addition, for the experimental bench with high requirements for impact resistance, it is necessary to use a solid stainless steel table with a large thickness, because the stone panel will crack or even break under a large blow, and cannot be repaired, and some stainless steel has better impact resistance than stone.

Depending on what kind of laboratory you have, if you have a physics laboratory, you can use an ordinary laboratory bench (physical and chemical plate, all-steel structure) - Xige.

The countertop is divided into three categories: chemistry laboratory countertop, physical laboratory countertop, and biological laboratory countertop, how to choose the right material for the countertop?

Chemical laboratory countertops are usually phenolic resin composite veneer countertops, phenolic resin solid board countertops, epoxy resin countertops, and ceramic countertops;

The physical laboratory countertop is usually phenolic resin composite veneer countertop and natural granite countertop;

Biological laboratory bench countertops are usually made of stainless steel plates and epoxy resin countertops.

There are mainly epoxy resin boards, solid core physical and chemical boards, ceramic plates, marble countertops, stainless steel countertops, etc.

The countertop is divided into chemistry experiment countertop, physics experiment countertop, and biological laboratory countertop.

1. Chemistry laboratory bench table.

Chemical laboratory countertops are usually phenolic resin composite veneer countertops, phenolic resin solid board countertops, epoxy resin countertops, and ceramic countertops;

Composite veneer countertops:

The material is a special board for chemical experiments with 1mm thick phenolic resin, a domestic high-quality MDF material for the substrate, a phenolic resin ordinary fireproof board pasted on the bottom surface, and a thick PVC material edge banding is used around the periphery; The composite thickness of the table is 40mm;

Solid board countertops:

The material is a thick phenolic resin board for chemical experiments, and the total thickness is 100 after edging; Perimeter chamfer r10mm; The high temperature resistance does not exceed 135.

Epoxy countertops:

The thickness of the material is 13mm, 20mm, 25mm for selection;

Features: a. 24-hour strong acid and alkali corrosion resistance; b. It has strong wear resistance, impact resistance, pollution resistance, and no bending; c. High temperature resistance up to 600;

2. Benchtop for physics:

The physical laboratory countertop is usually phenolic resin composite veneer countertop and natural granite countertop;

Composite veneer countertop, material: 1mm thick phenolic resin physical experiment special board, with high temperature resistance, wear resistance, scratch resistance and other characteristics. The substrate is made of high-quality MDF material, and the periphery is edged with thick PVC material; The composite thickness of the table is 40mm;

Solid board table, material: Thick phenolic resin board is used as a special board for physical experiments, which has the characteristics of high temperature resistance, wear resistance, scratch resistance, and anti-static. The total thickness after edging is; Perimeter chamfer r10mm;

Features: a. Strong wear resistance, impact resistance, pollution resistance, high temperature resistance, anti-static, no bending;

b. The maximum load is 300 kg square meters;

c. Temperature resistance can be used in -50 +40 environment;

Natural granite countertops:

Thickness: 50mm for high temperature table; 50mm for the sky platform;

Features: strong mechanical properties and heat resistance;

The maximum load capacity is 500 kg square meters;

Disadvantages: there is radiation, which is harmful to human health, (based on the test report);

3. Biological laboratory bench table:

Thick 316 stainless steel plate is selected, and the composite plate is lined with filling and sealing.

Features: 1. Resistant to organic solvents; 2. Inhibit the growth of bacteria and molds; 3. Anti-pollution and easy to clean;

Epoxy countertops:

The thickness of the material is 20mm, 25mm for selection;

Features: a. 24-hour strong acid and alkali corrosion resistance; b. It has strong wear resistance, impact resistance, pollution resistance, and no bending; c. High temperature resistance up to 600;

Hello, I am happy to serve you and give you the following answer: Yes, plastic countertops are commonly used in chemical laboratories. They have the advantages of corrosion resistance, wear resistance, state resistance, pollution resistance, and easy cleaning, which can meet the safety requirements of the laboratory.

The steps to solve the problem of plastic countertops are as follows:1First of all, check whether the countertop is damaged, and if there is damage, it should be repaired or replaced in time.

2.Secondly, the countertops should be cleaned regularly, which can be cleaned with warm water and detergent to prevent the accumulation of contaminants. 3.

Finally, check the condition of the countertop regularly, and if you find any damage, you should repair or replace it in time. Tips for sail model spring people: 1

When using the plastic code smart material countertop, pay attention to avoid the contact of high-temperature items to avoid damage to the countertop. 2.When cleaning countertops, be careful not to use detergents that contain acids and alkalis to avoid damaging countertops.

3.When using plastic countertops, be careful not to place heavy objects on the countertops to avoid damage to the countertops.

The main components of ceramic countertops include kaolin, clay, porcelain stone, porcelain clay, colorants, blue and white materials, lime glaze, lime alkali glaze, etc., which can be applied to various furniture surfaces in the laboratory, such as laboratory consoles, high-temperature tables, high-temperature tables, ** tables, side tables, sink tables, fume hoods, etc.

Comparatively speaking, the ceramic countertop is more expensive, which is considered a luxury item in the laboratory countertop, and there are relatively few domestic applications. However, it has two outstanding properties, one is that the ceramic countertop has particularly good high temperature resistance (usually above 1200 °C, and some can also reach 1500 °C). Second, it is very suitable for laboratories with high requirements for acid and alkali resistance, because the ceramic countertop is not sensitive to strong acids and alkalis other than HF, and the corrosion resistance is much higher than that of other materials.

In addition, ceramic countertops also have the characteristics of scratch resistance, anti-bacteria, anti-glaze cracking, high hardness, impact resistance, pollution resistance, good color fastness, anti-aging, easy to clean, environmental protection (no radiation, non-flammable, no release of toxic substances when heated) and so on.
