Usage:
Absorb and discharge sulfuric acid with a concentration not exceeding 40%, hydrochloric acid with a concentration of 30%, sodium hydroxide solution with a concentration of 15%, and equivalent acidic and alkaline solutions of the above concentrations (excluding nitric acid).
Usage temperature: Acid and alkali absorption and discharge: -20 ℃~+45 ℃ Heat absorption:- 20℃~+85℃
Structure:
The inner rubber layer is made of synthetic rubber such as nitrile rubber, natural rubber, styrene butadiene rubber, carbon black, etc., and the skeleton layer.
For synthetic fabrics or curtain layers, spiral steel wire layers, and outer rubber layers made of synthetic rubber such as natural rubber, styrene butadiene rubber, carbon black, etc.
Omnipotent Conveyor Expert in Complex Industrial Environments
Three in one durability, breaking through limits
Extreme temperature adaptability
High/low temperature resistance range: -40 ℃~200 ℃ (instantaneous temperature resistance up to 250 ℃), using a composite structure of * * silicone rubber (inner rubber layer)+EPDM rubber (outer rubber layer) * *, with no brittle cracking at low temperatures and no deformation at high temperatures.
▶ Actual testing verification: After continuous immersion in hot oil at 180 ℃ for 24 hours, the tensile strength retention rate is ≥ 90%; -Bending 180 ° at 30 ℃ without cracks.
Strong chemical resistance
Acid alkali tolerance range: pH 1-14, fully compatible. The inner rubber layer is coated with fluororubber (FKM) and polytetrafluoroethylene (PTFE), which can transport strong corrosive media such as 98% concentrated sulfuric acid, 30% sodium hydroxide, aqua regia, etc.
▶ Corrosion test: Immersed in a 50% nitric acid solution for 72 hours, the swelling rate of the inner rubber layer is less than 1.5%, far exceeding that of ordinary rubber (swelling rate>5%).
Wear resistant and pressure resistant dual guarantee
Compressive performance: working pressure of 6-10Bar, burst pressure ≥ 30Bar. The reinforcement layer is made of aramid fiber weaving and stainless steel wire spiral skeleton, with a negative pressure resistance of -0.09MPa, eliminating the risk of suction collapse.
Wear resistance index: Wear resistance ≤ 80mg (ISO 4649 standard), with a service life of 2000 hours when transporting quartz sand (particle size 1mm), which is four times that of ordinary rubber hoses.
