The seemingly easy question of “How waterproof are your products?” is not as simple to answer as you may think! Water is easy to keep out – but water vapour permeates through every material – and in doing so causes several billion pounds of waste to UK industry every year.
Versaperm有一系列的检测仪器，以帮助企业解决问题的措施和渗透率为材料样品和复杂的成品或组件。 结果通常是准确的百万分率（PPM）范围（PPB对于一些材料和气体），并且在一些情况下，这只需30分钟。 渗透性是制造如即使是简单的过程，如弯曲或成形，可以增加蒸汽的由四个因素渗入包装或产品内的量是至关重要的。
Permeability problems are often non-intuitive and highly complex, for example, silicone is very good barrier against water as a liquid – but it is virtually useless against water vapour which can pass through it almost as if it wasn”t there. The problems this creates are legion throughout almost every UK industry – from aerospace to fashion and from electronics through to food and packaging.
Versaperm”s equipment allows designers and manufacturers to test materials which bypass their problems. It also enables QC departments to check both incoming materials and outgoing products, without causing unnecessary delays.
Versaperm”s latest instrument and sensor range can actually measure permeability not just for water vapour, but for virtually any gas or vapour used by industry, including oxygen, carbon dioxide, hydrocarbons, helium, argon and nitrogen. The system can measure several material samples, seals, enclosures or products at a time.
Water vapour is far and away the world”s most widespread and damaging contaminant, it causes electronics to fail, machines to jam, drugs to lose potency, metal to rust and a host of other common failures.
