Water body covering medium Plastic Hollow ball

Short Description:

This ball was made by blow molding technology. So this ball has not any cracks.Traditionally, this ball is used in water treatment. When millions of Plastic Hollow ball onto the surface of a liquid, the balls automatically form a liquid covering surface. This covering surface provides an extremely effective barrier and significantly reduces the mass and heat transfer mechanisms operating between the liquid and surrounding environment.

At present, according to scientists’ continuous development and innovation, this balls application will become more wider. Such as prevent birds from landing and nesting on the liquid’s surface and around place,use as a check-valve ball in flow control applications, shock absorption in building field and so on.

Name

Application

PP

Polypropylene balls are resisting into not concentrated acids, alkalis, alcohols, oils, greases and most inorganic compounds. Fair resistance in aromatic hydrocarbons, they are not resistant in contact with halogens. They provide corrosive phenomena even in presence of concentrated acids and oxidizing agents at high temperature.

PE

Excellent corrosion resistance in contact with acids, alcohols, basis, esters, petrol, greases and oils. Fairish resistance to aliphatic and aromatic hydrocarbons, mineral oils, oxidizing agents.

PVDF

Excellent corrosion resistance in contact with inorganic acids and salts, organic acids, alcohols, ethers, aliphatic and aromatic hydrocarbons, halogens except fluorines, oxidizing environments. They are not suitable against nearly pure strong acids and basis, liquid alcaline metals, strong polar solvents.

PTFE

Teflon balls provide exceptional corrosion resistance properties, they are resisting even in contact with industrial acids or caustic substances. They suffer corrosive phenomena only against molten alkaline metals and fluorides at elevated temperatures.
