PP- Characteristics of polypropylene mesh demister
Physical property:
Polypropylene for non-toxic, odourlessness, tasteless cream color high crystallization polymer, density only then 0.90~0.91g/cm3, is in the present all plastics one of lightest varieties. It adds water specially stably, in the water the 24h water-absorptivity is only 0.01%, molecular weight approximately 8 ~ between 150,000. The formability is good, but because the shrinkage is big, thick article easy hollow. The product varnish is good, easy to color.
Mechanical properties: The polypropylene crystallinity is high, the structure is neat, thus has the fine mechanical properties, its intensity and degree of hardness, the elasticity are higher than HDPE, but under room temperature and low temperature, because molecular structure neat is high, therefore the shock strength is bad, the molecular weight increases, the shock strength also increases, but formation workability variation. The PP most prominent performance is the anti-bending gatigue, if casts a body activity hinge with PP, can withstand 7× 107 the inferior make and break enfold to be curving, but the non-damage trace, the dry friction coefficient is similar with the nylon, but under the oil lubrication, is inferior to the nylon.
Thermal properties: Pp has the good thermal stability, the melting point in 164~170℃, the product can in 100℃ above the temperature carry on the disinfection to be antiseptic, in the external force, 150℃ does not distort. The brittle temperature for - 35℃, will be being lower than - 35℃ will have the embrittlement, the resistance to cold is inferior to the polyethylene.
Chemical stability: The polypropylene chemical stability is very good, besides can by the strong sulfuric acid, the aqua fortis corrosion, quite be stable to other each kind of chemical reagent, but the low molecular weight' s fat hydrocarbon, the aromatic hydrocarbon and the chlorhydrocarbon and so on can cause PP to soften and the swelling, simultaneously its chemical stability increases along with the crystallinity also improves, therefore the polypropylene suits manufactures each kind of chemical pipeline and the fitting, the corrosion preventing effect is good.
