Polypropylene mesh demister is composed of PP vapor-liquid filter, consisting of PP grille screen block and the fixed screen block support device, the wire mesh demister can not only filter the suspended in a gas in a larger liquid foam, and can filter out small and tiny liquid foam, widely used in environmental protection engineering in flue gas desulfurization, factory production in the process of flue gas in addition to water, fog, dust removal, removal of harmful substances, purify the air, protect environment.

Polypropylene mesh demister features: simple structure and light weight, high porosity, small pressure drop, the contact surface area is large, defoaming high efficiency, installation, operation, convenient repair, long service life, s ested that the working temperature of not more than 90 DEG

PP PP physical properties: Polypropylene non-toxic, odorless, tasteless white high crystalline polymer, density of only 0.90 ～ 0.91g/cm3, is present in all the varieties of plastic light.Its water is particularly stable, in water 24h water absorption rate of only 0.01%, about 8 to 150000 molecular weight.Forming a good, but because the shrinkage rate is large, thick-walled products easy sag.Products good surface gloss, easy coloring.

The mechanical properties of polypropylene PP PP: the high crystallinity, regular structure, so it has excellent mechanical properties, its strength and hardness, elasticity is higher than HDPE, but at room temperature and low temperature, because of their molecular structure of regular degree is high, so the impact strength is poor, the molecular weight increases, the impact strength is also increased, but the processing performance variation.PP most prominent performance is the bending fatigue, such as using PP molded integrally movable hinge, can withstand 7 × 107 open-close folding bending without damage, dry friction coefficient and nylon are similar, but under oil lubrication, not as good as nylon.

PP polypropylene chemical stability: polypropylene chemical stability is very good, in addition to being concentrated sulfuric acid, nitric acid erosion, the other a variety of chemical reagents are relatively stable, but the low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make PP softening and swelling, and its chemical stability decreases with the increase in crystallinity there is increased, so the polypropylene suitable for production of a variety of chemical pipelines and accessories, very good corrosion resistance performance
