What Are The Countertops Of The Laboratory Bench?
May 22, 2018

Test bench is the most easy damage part of the laboratory equipment, the choice of its mesa material directly affect the use of the test bench and the correctness of the experimental results, so want to choose a beautiful, laboratory bench durable and meet the requirements of the experimental platform is very important.

At present, there are several kinds of mesa materials sold in our country.

1. The wooden table

Usually adopt solid wood mesa, it has the appearance to feel warm, easy to repair, glass ware not easy to touch bad etc. laboratory bench The drawback is that the wood processing or production methods are not adequate. There will be cracking and warping. The thickness of the mesa is suitable for 32mm, the wood is good with hemp and chestnut, also can use birch, armhole and so on. The table can be treated with traditional lacquer or aniline black to enhance its acid resistance, as well as the anticorrosion synthetic resin coating. Because of the difficulty of high quality wood source, it is also considered to adopt a 32mm composite plate, with a wood bar in the middle, and a variety of suitable synthetic materials. If use wooden mesa, should undertake chemical treatment. For example, the leach (or tannin) leach, the use of liquid and other methods.

2. Cement stone table.

The cement stone countertops are made of cement reinforced concrete, water grindstone, marble, natural granite and other inorganic stone decoration. It is mainly used in stationary test bench with stable, strong and high temperature resistance. Used for the chemical test bench to lay a thick rubber sheet, also can be used in the steel bracket on the experimental table.

3. The surface of the reinforced concrete k structure can also be tiled, while the ceramic tile is not resistant to hydrofluoric acid, laboratory bench but it has good tolerance to other drugs and solutions. The disadvantage is that glassware is liable to be damaged. Ceramic tiles should be made of acid resistant materials.

4. Steel countertops

Steel countertops are generally made of stainless steel surfaces with a thickness of 1.2mm stainless steel plates. Good heat resistance, good impact resistance, easy to remove rust and contamination, good bearing capacity, laboratory bench can be installed on steel tube frame. This kind of mesa is beautiful and durable, suitable for use in other laboratories other than chemistry lab, such as radiochemistry, biochemistry and oil test, etc., high price.

5. Synthetic resin table.

Synthetic resin mesa is a kind of high density, high polymer synthetic resin material. Good physical and chemical resistance. The synthetic resin is mostly melamine formaldehyde resin, epoxy resin and so on, has been used in the experimental mesa and water basin pool. There are a lot of epoxy countertops in the market, but they are mainly imported from the foreign countries. The performance of this kind of mesa is good, laboratory bench no matter from its acid and alkali resistance, high temperature, impact, the ability to write, its cost performance is the first choice of the laboratory at present. Good quality, such as a kind of American imported high-grade mesa material, mainly for reinforced epoxy resin composition. There is a smooth and secure arc - type edge, which is a mold - forming chemical platform panel. Internal and external materials are consistent, and can be repaired and restored when damaged. With excellent acid and alkali resistance, impact resistance, resistance to high temperature (800 ℃).

6. Resistant to physical and chemical boards.

1 mm thick, corrosion-resistant chemical framework and honeycomb structure, which is of strong acid, alkali, oxidant, scratch resistance, abrasion resistance, corrosion resistance, high basin, the surface no wool stoma for environmental protection material, such as black, white, grey color.

7. Thin solid core physical and chemical board table.

The surface material is 6mm thick solid physical and chemical board, its performance is the same as the corrosion resistant physical and chemical board.

8. Solid physical and chemical surface.

The thickness is 12.7mm,15mm,20mm, 25mm solid physical and chemical plate processing and trimming molding, surface without capillary, easy to clean, is a more ideal surface material. Good acid and alkali corrosion resistance. laboratory bench Applicable to clean laboratory.

9. High decoration fire prevention board table.

The surface material is 1mm high decoration fire prevention board, frame and honeycomb structure, the surface is smooth and uniform, the color is black, gray, white, green and so on.

10.TRESAP

The composition is 70% wood fiber. 30 % of the melamine resin, using double electron beam scanning patent technology to attach melamine to the surface layer, through high temperature and high pressure molding. It is widely used in laboratory of chemistry, biology and physics. Long service life.

11. Physical and chemical paste panel.

It is processed by high temperature and high pressure by adding special phenolic resin impregnated kraft paper, colored paper and special surface paper. It has the characteristics of acid and alkali resistance, impact resistance, heat resistance, economical and durable (with the use of base materials), and it is used in hospital, photo studio and product deep test laboratory.

At present also useful artificial stone as the experimental mesa, this kind of mesa is more beautiful, waterproof, laboratory bench but antiacid alkalinity is poorer, prevent organic solvent such as phenol is worse. There is also a kind of solid core physical and chemical board, this kind of fabric has all kinds of properties, especially the strong acid and alkali resistance is very good, but the price is expensive. Note, however, that there is also a kind of anti-double board, which has the same appearance as the solid physical and chemical plate, but it is not resistant to strong acid and alkali, and the price is only about half of the physical and chemical plate.
