The maintenance of the test bench
Among all laboratory furniture, the lab bench is the most frequently used laboratory furniture in the laboratory. How can we effectively clean and maintain the lab bench, thus reducing the loss of the lab bench and extending its working life? Let us now look at how to effectively maintain the bench.
the test bench classification
According to the function, the test bench can be divided into a central station, a side table, a washing station, an instrument table, a chromatographic table, a console, a purification station, a physical table, etc.; according to the material, it can be divided into an all-steel test bench, a steel-wood test bench, and an aluminum wood. The test bench and the all-wood test bench are gradually phased out before the last three projects.
Resin artificial stone
It is the most commonly used artificial stone. The cost analysis of artificial stone within 800 yuan/meter on the market belongs to “unsaturated resin board”, and the price changes within 800 yuan, which is affected by the quality of resin raw materials and filler.
Composite artificial stone
Due to price factors, they are less common and not very well recognized. Whether the content of acrylic components (ie: mmA) needs to be detected after testing, therefore, belongs to the “integrity problem” of the enterprise.
Acrylic artificial stone
Also known as methyl polymethyl acrylate or MMA, the main advantage of acrylic is that it can be arbitrarily deformed and bent after heating, and the price is expensive.
Natural stone countertop
Mainly imported marble, granite material, it is a fashionable, and design-oriented countertop with potential for development in China.
Advantages: pure natural stone, the pattern is harmonious and beautiful, the luster is soft, the texture is ever-changing, and there is a feeling of returning to nature. The whole stone can be carved, luxurious bathtub, wash basin, washbasin, countertop and various decorations, with practical and decorative features. High hardness, scratch resistance, abrasion resistance, high temperature resistance, and environmental protection.
Disadvantages: too hard, not easy to repair after damage
Stainless steel countertop
Advantages: high hardness, firm, practical, easy to clean; corrosion resistant; anti-penetration.
Disadvantages: Not very suitable for the particularity of the crossover of civil kitchen pipes.
Fire board countertop
Advantages: scratch resistance, corrosion resistance, high temperature resistance; impact resistance, flexural resistance, pressure resistance, and penetration resistance.
Disadvantages: Can not be repaired after scratching; can not be seamlessly bonded.
Solid wood knuckle countertop
Advantages: good texture; good environmental protection; not easy to deform, scratch can be repaired.
Disadvantages: not resistant to penetration. Can not be seamlessly bonded; can not meet the individual needs of customers; less color, poor selectivity.
Solid wood multi-layer countertop
Advantages: high environmental protection, high value, high density, antibacterial, mildewproof, acid and alkali resistant, anti-pollution, easy to clean, no paint smell, no fir flavor, etc.
Bench maintenance
1, the opening and closing of the experimental cabinet door and drawer should be light and light;
2, the laboratory cabinet should store ordinary laboratory consumables and equipment. If there are acid, alkali reagents and volatile solvents, they should be stored in a special safe storage cabinet;
3, when scrubbing the test bench, it should be scrubbed with a soft cloth. The detergent should be diluted before use. Do not use abrasives and strong acid cleaners. Do not rinse at high temperature. It is best to prepare warm water. Wipe the test bench with mild detergent. . For substances that are difficult to remove, use hypochlorous acid to drip on the surface of the contaminated physicochemical board and rinse with water;
4, the test cabinet cabinet is not available with soluble detergent. All benzene solvents and resin solvents should not be used as panel cleaners.
5. The test bench cannot be moved out of the laboratory and exposed to high temperature and strong light. This will cause the plating of the surface of the test bench to be destroyed, affecting the aesthetics of the test bench and shortening the service life of the test bench. It should not be placed in a particularly dry state. Places, otherwise it will cause cracking.
6. In the process of using alcohol lamps, the alcohol lamp should not be placed directly on the test bench. The high temperature flame will burn the test bench. The alcohol lamp should be placed on the stand.
7. After the experiment is completed, the water on the surface of the clean bench should be wiped clean, and all the accumulated water in the sink should be discharged;
Eight, if the utensils are broken, you need to grab them by hand. Do not use a rag to wipe the test, otherwise it will cause scratches on the table.
9. Although the ventilated countertop can withstand high temperatures, it is not recommended to be in direct contact with open flames and high temperatures for a long time.
10. Although the ventilated countertop has good corrosion resistance to various chemicals, it may have some effects when it is exposed to immersion for a long time. Therefore, it is recommended that if chemicals are dropped on the countertop, they should be removed as soon as possible.
The above is the maintenance method of the test bench, we can learn to extend the service life of the test bench.
