三,保温材料憎水性测仪操作步骤:
★将试样放入干燥箱内,在105±50C的温度下干燥至恒重。当试样在此温度下易变形或含有易挥发易变化的组分时,可在60±50C或小于挥发温度5-100C的条件下干燥至恒重。称量试样的质量m1。
★测量干燥后试样的尺寸。对板状制品,长度和宽度的测量在试样的正、反两面进行,各测4次,读书精确到1mm。软质制品的厚度测量采用测厚仪,硬质制品的厚度测量采用游标卡尺,沿试样长度方向均匀地测3个点,读数精确到0.1mm。对管状制品内、外径的测量应在试样的两端进行,各测4处。长度测量两次。读数精确到1mm。试样各尺寸的测量结果均取平均值。计算出试样的厚度(或壁厚)及体积。
★将试样安放在憎水性侧试仪上(对单面做憎水处理的试样,应分别测其两面的憎水性,对板状制品,应根据试样厚度,调节喷头位置,使其满足图1要求。对管状制品,应使其内表面向下,调节喷头位置,使试样上半部分均匀受淋),调节水流量,使其稳定在 1L/min,连续喷淋lh,然后,取下试样,用皱纹纸快速吸取表面水滴,立即称量试样的质量m2。
Third, the operation steps:
★ Place the sample in a dry box and dry to a constant weight at a temperature of 105 ± 50 °C. When the sample is easily deformed at this temperature or contains a volatile and easily changeable component, it can be dried to a constant weight at 60 ± 50 C or less than the volatilization temperature of 5 - 100 °C. Weigh the mass m1 of the sample.
★ Measure the size of the sample after drying. For the plate-like products, the measurement of the length and width was carried out on both the front and back sides of the sample, and each test was performed 4 times, and the reading was accurate to 1 mm. The thickness of the soft product is measured by a thickness gauge. The thickness of the hard product is measured by a vernier caliper, and the points are evenly measured along the length of the sample, and the reading is accurate to 0.1 mm. The measurement of the inner and outer diameter of the tubular product shall be carried out at both ends of the specimen, and each test shall be carried out at four locations. The length is measured twice. The reading is accurate to 1mm. The measurement results of each size of the sample were averaged. Calculate the thickness (or wall thickness) and volume of the sample.
★ Place the sample on the hydrophobic side tester (for the sample treated with water on one side, the water repellency on both sides should be measured separately. For the plate-shaped product, the position of the nozzle should be adjusted according to the thickness of the sample to make it Meet the requirements of Figure 1. For tubular products, the inner surface should be downward, adjust the position of the nozzle, so that the upper part of the sample is evenly drenched, adjust the water flow, stabilize it at 1L/min, continuously spray for lh, then Remove the sample, quickly absorb the surface water droplets with crepe paper, and immediately weigh the mass m2 of the sample.

四,保温材料憎水性测仪试样:
板状制品试样的尺寸为300mm*150mm,厚度为制品的原厚。管状制品试样长300mm,横截面为半环形或扇形,壁厚为制品的原壁厚。制备试样时应尽可能使试样具有代表性,不要从带有折皱或表面破损的部位取样。泡沫塑料制品应去除表皮。
Fourth, the sample:
The size of the plate-shaped product sample is 300 mm * 150 mm, and the thickness is the original thickness of the product. The tubular product sample is 300 mm long, has a semi-annular or fan-shaped cross section, and the wall thickness is the original wall thickness of the product. When preparing the sample, the sample should be representative as much as possible. Do not sample from the part with wrinkles or surface damage. Foam products should be removed from the skin.

五,保温材料憎水性测仪原理:
将试样与水平呈450角放置,试样中心位于喷头下面给定的位置,用一定的流量的水喷淋试样至规定时间,通过测量喷淋前后试样质量的变化,从而计算出试样中未透水部分的体积百分率。
Five, the principle:
Place the sample at a 450-degree angle with the horizontal position. The center of the sample is located at the position given below the nozzle. Spray the sample with a certain flow of water for a specified time. Calculate the test by measuring the change in the mass of the sample before and after spraying. The volume fraction of the unpermeable portion of the sample.
