Interpretation of PP spray tower performance characteristics and maintenance
PP washing tower comes from a new type of industrial waste gas treatment equipment in the society today. It is not only produced based on the improvement of industrial waste gas purifiers with floating filler layers, but is mainly used in industrial waste gas treatment and dust removal treatment. Because of the good purification effect, it is now used in acid and alkali waste gas treatment One of the commonly used and more practical processing equipment.
Performance characteristics of PP washing tower:
1. Physical properties: PP washing tower has stability to water, because the water absorption rate in water for 14 hours is only 0.01%. The molecular weight is about 80,000 to 150,000, and the moldability is also good.
2, mechanical properties: PP washing tower has high crystallinity and structure leaves are very regular, because it has very good mechanical properties, so its strength, hardness and elasticity are relatively high. In particular, it has resistance to bending fatigue, and the bending of the opening and closing has not been damaged, and the dry friction coefficient is very similar to nylon.
3. Thermal performance: PP washing tower has very good heat resistance, especially its melting point is 164 to 170 ° C. Products can also be sterilized at temperatures above 100 ° C. And it will not deform above 150 ℃ without being affected by external force. Embrittlement is -35 ° C, especially when the temperature is lower than -35 ° C, and the heat resistance is not as good as PE.
4. Chemical stability: PP scrubber has good chemical stability. Except that it can be attacked by concentrated sulfuric acid and concentrated nitric acid, it is basically stable to other chemical reagents. PP can be softened and swelled, and the chemical stability can be improved with increasing crystallinity. Therefore, PP is very suitable for the production of Russian-Chinese chemical pipes and fittings. The important thing is that the anti-corrosion effect is also very good.
5. Electrical performance: The insulation performance of PP washing tower is very good, because it basically does not absorb water, so this insulation performance is not affected by humidity, and also has a high dielectric constant, which will follow the temperature The rise in temperature, especially it can also produce heated electrical insulation products, not only the breakdown voltage is also very high, mainly used in electrical accessories and so on.
6. Weather resistance: The PP washing tower is very sensitive to ultraviolet rays. Adding zinc oxide thiopropionate dilaurate and carbon black type milky white filler can improve its aging resistance.
Second, maintenance and maintenance
The agency needs to perform an inspection and maintenance within 30 days after the commissioning and qualified use. The contents of inspection and maintenance are as follows:
1: Remove dust and dirt on the surface of the mechanism.
2: Whether the sprinkler is clogged.
3: Clean up the water tank for sediment clogging, and clean up the records, so that you can customize the next cleaning time.
4: Observe whether there are heavy stains on the surface of the Rashid ring. If found, you need to take them out and place them in a large area sink, and then use a neutralizing agent to remove the surface stains.
5: According to the exhaust odor or data to determine whether the activated carbon needs to be replaced, then the activated carbon after we use can be exposed to the sun to avoid bacterial regeneration.
6: Check the pump for abnormal noise, looseness and blockage.
External dimension: According to the customer's site requirements, the external dimension of the PP acid and alkali neutralization tower is formulated.
