雨水水珠直径的平均值如表1所示。从表1 中看出,高分子防水薄膜的孔隙直径比水滴直径小很多,甚至不到水滴直径的千分,所以在常温状态下,水以液态形式存在时,是不可能通过防水透气材料进入传感器内部的,而空气分子的直径比防水透气材料的孔隙直径小很多,可以透过,基于此该种材料就能达到防水透气的目的。1.3 防水透气材料的选择
防水透气材料主要分为以下四大类:高密织物、层压织物、涂层织物和膨化织物。
General waterproof and breathable materials are composed of polymer waterproof and breathable film and flame retardant cloth. There are tiny pores in the polymer waterproof and breathable film, and the diameter of the pores is a few tenths to dozens μ m。 The average value of rainwater droplet diameter is shown in Table 1. From Table 1, it can be seen that the pore diameter of the polymer waterproof film is much smaller than the diameter of the water drop, or even less than one thousandth of the diameter of the water drop. Therefore, at normal temperature, when water exists in liquid form, it is impossible to enter the sensor through the waterproof and breathable material, while the diameter of the air molecule is much smaller than the pore diameter of the waterproof and breathable material, and it can be penetrated. Based on this, this material can achieve the purpose of waterproof and breathable. 1.3 Selection of waterproof and breathable materials
Waterproof and breathable materials are mainly divided into the following four categories: high-density fabrics, laminated fabrics, coated fabrics and puffed fabrics.
