Bleach Hdpe
Sodium hypochlorite storage tanks are manufactured from hdpe xlpe and frp materials at 1 9 specific gravity.
Bleach hdpe. S satisfactory o some attack u unsatisfactory. If you wish to reuse a high density polyethylene bottle it must first be cleaned. Hdpe and ldpe at 20c show some effect after 7 days.
Tank capacities range from 35 to 100 000 gallons. Polyethylene hdpe and ldpe has a very good compatibility rating with most chemicals and is resistant to strong acids and bases as well as gentle oxidants and reducing agents. However preliminary tests showed that chemical interaction between hdpe and bleach occurring within six month of exposure to the product has a negligible effect on the materialâ s mechanical properties.
Secondary containment is required. Polypropylene is almost as resistant as polyethylene but with a few specific chemicals it offers superior resistance. C fair moderate effect not recommended for continuous use.
Hdpe chemical compatibility resistance chart explanation of footnotes 1. Hdpe chemical resistance guide legend. Satisfactory to 120 f 48 c ratings chemical effect a excellent.
Ldpe at 50c shows damage and is not recommended. Soap and water is all that is need to clean and reuse the bottles. Uv can degrade sodium hypochlorite so special precautions must be taken to reduce this effect.
At 50c immediate damage may occur. Softening loss of strength. Bleach is best stored out of direct sunlight at temperatures below 60 f filtered and diluted with ph kept above 10.

Satisfactory to 72 f 22 c 2. Not recommended for continuous use.
When storing this chemical three factors must be considered. Prices range from 300 to 150 000. Alums all types concentrated s s bleach lye 10 s s amino acetic acid s s borax cold saturated s s ammonia 100 dry gas s s boric acid concentrated s s ammonium acetate s s boric acid dilute s s.
Therefore in this work esc was investigated independently and only the results obtained from fracture tests are reported. B good minor effect slight corrosion or discoloration. Chlorine 10 in water hdpe and ldpe at 20c shows little or no damage after 30 days.
High density polyethylene abbreviated as hdpe is a type of plastic commonly used to make milk jugs laundry detergent containers soda bottles and floating water tanks.
