Multi-faceted hollow ball Product Description: ???? multi-faceted hollow ball in the middle along the entire circumference of a reinforcement ring, ring up and down in each twelve ball valve. Upper and lower ball valve with each other, along the central axis was radial layout. I plant in the production of engineering plastics unit help sum up the experience, confirmed that the product has the following advantages: Because the large surface area; high mass transfer efficiency of various departments, the product space is large, and light weight, high strength, easy installation, welcome widely used. Features: gas velocity high, leaves and more resistance; large surface area, can adequately address the air-fluid exchange; having a small resistance operating flexibility and so on. Widely used in addition to chlorine, in addition to oxygen, in addition to carbon dioxide gas and other environmental protection equipment. Molecular ┌ ...........

Scope: multi-faceted hollow ball is widely used in addition to chlorine, in addition to oxygen, in addition to carbon dioxide gas and other environmental protection equipment. Multi-surface hollow ball packing is placed in accordance with the desired height decarbonization or separator and other devices. Multi-faceted hollow ball performance: (1) physical properties of polypropylene is non-toxic, odorless, tasteless milky white highly crystalline polymers, density of only 0.90 to 0.91 g / cc, is one of the lightest of all the plastic brand. Polypropylene multi-faceted hollow ball, 24h water absorption in water is only 0.01%, the molecular weight of about 8 to 15 million. Formability, but shrinkage (of 1% to 2.5%), thick-walled products easy to depression, high precision parts for some size, but also difficult to meet the requirements. Product surface gloss, easy coloring. (2) the mechanical properties of highly crystalline polypropylene, regular structure, which has excellent mechanical properties, and its yield, tensile, compressive strength and hardness, elasticity than HDPE, but at room temperature and low temperature, because of their regular molecular structure and high strength so momentum is poor, the molecular weight increases, the impact strength also increased, but the processing behavior deteriorates. Polypropylene multi-faceted hollow ball has outstanding resistance to bending fatigue strength, as with PP injection - hinge body, can withstand seventy million times for opening and closing the fold bending without signs of damage, it is also good rub resistance, dry friction coefficient and nylon similar, but when oil lubrication, the friction performance is clearly not as good as nylon, PP can only be used to make low PV value and impact loads without gears and bearings. In terms of surface effects, such as in its article surface embossing, engraving, etc., it is easier than any other thermoplastics. (3) Thermal properties of polypropylene has good heat resistance. It is a melting point of 164 ~ 170 ℃, articles can be sterilized at a temperature above 100 ℃. When not under external force, 150 ℃ not deformed, stress relaxation resistance at 90 ℃ is good, it's brittle transition temperature of -35 ℃, at a temperature below -35 ℃ embrittlement occurs, cold resistance than polyethylene, if used after asbestos fiber and glass fiber reinforced, have higher heat distortion temperature, dimensional stability, low temperature impact properties. Chemical stability (4) chemical stability of polypropylene multi-faceted hollow ball well on a variety of other chemical reagents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons to make polypropylene soften and swell, At the same time it increases the chemical stability with the degree of crystallinity increased. Therefore, it is suitable for a variety of chemical pipes and fittings, corrosion effect is good. Good high-frequency insulation properties (5) electrical properties of polypropylene, because it almost does not absorb water, put insulation performance is unaffected by humidity. It has a high dielectric constant with increasing temperature can be used to produce heating of electrical insulation products, its high breakdown voltage, suitable for electrical accessories. Anti-voltage arc resistance, static high and easy to aging copper contacts.

Multi-faceted hollow ball is widely used in addition to chlorine, in addition to oxygen, in addition to carbon dioxide gas and other environmental protection equipment. Plastic multi-faceted hollow ball packing is composed of two hemispheres into one ball of each hemisphere by a number of fan-shaped leaves half composed, arranged and staggered by the fan-shaped leaves of the two hemispheres. Advantages of multi-faceted hollow ball packing is packing a large surface area, such as multi-faceted spherical packing Dg50, the specific surface area of ??up to 200m2 / m3 or higher. Plastic multi-faceted hollow ball packing used in sewage treatment, water treatment plants CO2 removal equipment, desulfurization, catalytic purification tower and tower and other devices. Multi-faceted hollow ball is widely used in sewage treatment, domestic water treatment plants CO2 removal equipment, desulfurization, catalytic purification tower and tower, chemical, paper, environmental protection industry until the decarbonization, decarboxylation, oil and water separation, desalination, water, devices using waste water, waste gas treatment. Multi-faceted hollow ball except the water treatment process in the role of carbon dioxide degassing tower is to remove the carbon dioxide in the ion exchange water, reducing the load on the anion exchanger, to improve the economic and effluent treatment systems. When the carbon dioxide content in the water (alkalinity) is greater than 50 mg / l, set up in addition to carbon dioxide degassing tower is more economical in the primary rehabilitation beds desalination systems. After degassing tower treatment, the residual carbon dioxide content in the water of 5-10 mg / liter. Multi-faceted hollow ball main purposes: Widely used in addition to chlorine, oxygen.
