How to choose a laboratory fume hood from the material structure:

The common fume hoods on the market today are steel-wood fume hoods, all-steel fume hoods, glass fiber reinforced plastic fume hoods, and PP fume hoods. The following is a detailed description of the materials used in various types of fume hoods:

1. The material of steel-wood fume hood is explained as follows:

1. Support frame: 40 × 60mm thick 1.5mm cold-rolled steel pipe is used for processing and manufacturing. The metal surface is pickled and rust-removed, phosphated and deacidified, electroplated, electrostatic sprayed epoxy powder is baked at high temperature. The screw holes of the connecting piece are welded by the riveting process. After welding, the appearance is flat and there are no welding point marks. All the screws of the support frame are connected with national standard hexagonal stainless steel screws.

2. Cabinet: Use high-quality melamine to prevent moisture and fire, and use 18mm thick medium density board as the base. The sawing surface is made of hot-melt adhesive, PVC edge banding leather, and automatic edge banding machine edge banding, which is moisture-proof, wear-resistant and beautiful.

3. Deflector: The three-stage deflector design makes no dead corners in the cabinet, and all kinds of specific gravity gases can be cleaned out of the cabinet smoothly.

4. Countertop: 12.7MM thick laboratory-specific solid-core physical and chemical board is used, which is resistant to acid and alkali, anti-humidity, impact resistance, antibacterial and easy to clean.

5. Viewing window: 6mm thick tempered safety glass is used, which can be lifted and lowered in any direction. It can stay in any orientation. The sliding part is made of corrosion-resistant and wear-resistant new composite material.

3. The material of FRP fume hood is explained as follows:

FRP fiber is light and hard, non-conductive, high mechanical strength, less recovery and corrosion resistance, and can replace steel parts to manufacture machine parts and automobile and ship shells. It is glass fiber reinforced plastic that has the above characteristics. Laboratory fume hoods made of this material have no deformation, no rust, paint, fade, high temperature, acid and alkali resistance, corrosion resistance, high strength, and flame resistance Among other advantages, it has been widely used in the manufacture of laboratory fume hood products. The characteristics of FRP fume hood:

1. Strong anti-corrosion function: FRP has extensive anti-corrosion function. It is suitable for operation positions and occasions where acid and alkali gas, toxic and harmful gas, organic solvent gas and dust occur.

2. Operating table: 12.7mm thick high-quality solid core physicochemical board, acid and alkali resistant, anti-wetting, and impact resistant.

3. Conditioning door: two-section safety tempered glass, stepless balanced lifting, can be moved up and down to stay in any position.

4, lighting equipment: anti-corrosive fluorescent lamp, the light source is isolated from the gas, the table surface illumination is greater than 400 lumens.

5. Operation panel: lighting switch, fan ON / OFF switch, two 220V, 10A multifunctional sockets.

6, light weight, high strength: FRP can withstand a temperature of 80 ℃ for a long time, short-term can reach 130 ℃, FRP oxygen index ≥ 30, is a flame-resistant material.

7, anti-aging, long life: generally used for more than 15 years.

Fourth, the material of PP fume hood is explained as follows:

PP material has outstanding acid resistance, easy cleaning, oxidation resistance, good surface finish and so on. Therefore, people have made it to be able to engage in higher strength acid and alkali laboratory fume hoods, and its excellent characteristics are irreplaceable by other fume hoods. Particularly suitable for metallurgy laboratories, environmental protection laboratories, exhaust air and detoxification.

1. Cabinet: It is made of anti-acid and chemical resistant, impact-resistant magnetic white PP board, 8-10mm thick. With strong acid resistance, chemicals, impact resistance, no corrosion, no rust and other characteristics.

2. Exhaust lining: Use acid- and alkali-resistant PP board as the lining material, and the thickness is more than 8mm.

3. Window sliding door system: made of 5mm tempered glass, the handle frame and chute are made of PP injection molding, which has acid and alkali resistance and explosion-proof effect.

4. Lighting device: two sets of fully sealed 30w fluorescent lamps, 220v.

5. Lower cabinet: double-open doors, the internal space can be used for drainage pipes, lines and storage space.

6. Adjusting feet: plastic steel mold is used for molding, no metal is exposed, and it can be adjusted according to the height on the ground.
