Detailed description

PLOY polymer PO is the English abbreviation of the Chinese name of the polyolefin is a polymer of ethylene homopolymers and ethylene , propylene , butene polymerization of olefins , including some features blends , and composites reinforced . It is a new corrosion-resistant , anti-static , non-toxic , high strength and good rigidity lining material . Operating temperature -20 ℃ ~ 90 ℃, with a special hot melt rotational molding new processing technology , the price is relatively low , as the lining and steel adhesion is strong. Now in the domestic chemical industry, metallurgy, food, transportation, medicine , chlor-alkali , shipping , mining, textile and other industries widely used, and the process of internal and external structure of the workpiece is not required, the complexity of the structure of the workpiece , can molding , deep welcomed by users . As the polyolefin (PO) are ethylene, propylene and butene copolymerization of an olefin copolymer , it not only maintains the ethylene , propylene, corrosion resistance , and has good heat resistance , impact resistance and electrical insulation properties . The use of temperature 20-30 degrees higher than polyethylene . It overcomes both polyethylene and polypropylene and metal poor adhesion shortcomings, has a strong cohesive force , with the metal firmly together, is currently the world's best anti-corrosion materials. Thus , with its lined equipment, pipes and fittings can withstand vacuum , vacuum up -0.092MPa. Meanwhile, a strong binding force , which greatly limits its changes due to thermal contraction and elongation caused to roll PO equipment, pipes and fittings contraction and expansion will not cause damage , the device ensures the long-term stability . Polyolefin (PO) for various concentrations of certain organic acid salt solution and the solution .

Lined polyolefin (PO) Advantages:
1 forming a whole , no welds, no joints , corrosion resistance , aging resistance, no cracks, resistance to negative pressure , not falling . All surfaces are disposable liner forming, no artificial binding sites and the operation of welding points ; thus overall good , no defects, seamless point .
(2) can be any shape steel roll lining, installation, maintenance is simple, be secondary repair cost savings. Product appearance smooth, no bubbles , non-toxic , no pinholes.
3 quality materials : imported and domestically produced exclusively for the production of corrosion-resistant carbon steel equipment lined polyolefin resin .
4 Professional Recipe: According to film theory , improved PO resin ratio, so that the various parts of the lining layer to optimize portfolio performance .
5 unique thermal melt molding process: lining at different stages of strict temperature control , making it including the underlying , structure layer and the surface layer forming one of the effective molecular crystallization , thereby improving the corrosion resistance of the product , anti-permeability and composite performance and the jacket .
6.PO overcome rubber , PE, PP and PVC liner due to the presence of the weak secondary structure formed by processing a common problem easily damaged , such as the lining material of the welding ( or bulk adhesive ) Office, and the pipe flange mouth , etc., with overall performance of equipment , rigidity strength, resistance against hydrofluoric acid and other advantages.
7.PO by hot melt molding , material selection and modification , the lining layer and the metal body combined into a solid compact whole, may be at a higher temperature or ambient temperature change more frequently in long-term use , to overcome the usual non-metallic liner products ( rubber , PE, PP , and PVC, etc. ) due to thermal expansion and contraction of the bubble , delamination and other damage.
8 lined polyolefin (PO) Product Application: widely used in petroleum , chemical industry, machinery, metallurgy , pharmaceuticals, dyes, food , biochemical , textile, electroplating, environmental protection and other fields. Coating of various concentrations of inorganic acids, organic acids, alkalis , salts are stable . At -20 ℃ ~ 90 ℃ temperature range is rubber , enamel, glass, steel, stainless steel, plastic plate ( tube ) ideal alternative materials such as lining .

PO and rubber are commonly used hydrochloric acid storage tank lining material, resistant to acid corrosion effects are very good , suitable temperature range close to , and the price is roughly equal. From the analysis of the performance characteristics PO , PO as hydrochloric acid storage tank lining materials more cost-effective than the rubber lining , its main advantage is reflected in the following two aspects:
1), PO chemical stability, anti-aging , long life, PO hydrochloric acid storage tank lining service life up to 30-50 years ; rubber easy to aging, life is impossible to achieve 30 years.
2), PO has a strong adhesive force , PO liner to the steel body by lining tightly, with frequent changes in temperature will not occur delamination ; rubber-lined steel liner easily from the subject , in particular with the use of the temperature rise high , prone to degumming , causing steel corrosion , which occurred in hydrochloric acid spill , while shedding rubber may clog the piping connections .
