Protective clothing against acid test system is the main inspecting device for application LA safety mark and industrial product production license for acid proof protective clothing. The device divides to static acid pressure tester, acid and alkali repellant tester, and acid penetration time tester.
Acid penetration tester is mainly used for measuring the penetration time of acid and alkali proof chemical fabrics.
Aplikasi
Acid penetration tester is used for water proof air permeability testing of high density fabric, laminated fabric, and coating material etc. Such as canvas, such as canvas, felt, tarpaulin , cover cloth, airtight fabric, outdoor sports material, umbrella testing and waterproof material testing etc. It can be also used for testing liquid and blood permeability testing of medical protective clothing, and chemical material liquid permeability testing of chemical protective clothing, liquid permeability testing of non-woven, filter material, it can be also used for water permeability testing of paper and card board .
