三、保溫材料憎水性測定儀操作步驟：

★將試樣放入干燥箱內，在105±50C的溫度下干燥至恒重。當試樣在此溫度下易變形或含有易揮發(fā)易變化的組分時，可在60±50C或小于揮發(fā)溫度5-100C的條件下干燥至恒重。稱量試樣的質量m1。

★測量干燥后試樣的尺寸。對板狀制品，長度和寬度的測量在試樣的正、反兩面進行，各測4次，讀書**到1mm。軟質制品的厚度測量采用測厚儀，硬質制品的厚度測量采用游標卡尺，沿試樣長度方向均勻地測3個點，讀數(shù)**到0.1mm。對管狀制品內、外徑的測量應在試樣的兩端進行，各測4處。長度測量兩次。讀數(shù)**到1mm。試樣各尺寸的測量結果均取平均值。計算出試樣的厚度（或壁厚）及體積。

★將試樣安放在憎水性側試儀上（對單面做憎水處理的試樣，應分別測其兩面的憎水性，對板狀制品，應根據(jù)試樣厚度，調節(jié)噴頭位置，使其滿足圖1要求。對管狀制品，應使其內表面向下，調節(jié)噴頭位置，使試樣上半部分均勻受淋），調節(jié)水流量，使其穩(wěn)定在 1L/min，連續(xù)噴淋lh，然后，取下試樣，用皺紋紙快速吸取表面水滴，立即稱量試樣的質量m2。

Third, the operating steps of the insulation material hydrophobicity analyzer:

★ Put the sample in a drying box and dry to constant weight at 105 ± 50C. When the sample is easily deformed or contains components that are volatile and changeable at this temperature, it can be dried to constant weight at 60 ± 50C or 5-100C less than the volatilization temperature. Weigh the sample m1.

★ Measure the size of the sample after drying. For plate-shaped products, the length and width are measured on the front and back sides of the sample, each of which is measured 4 times, and the reading is ** to 1 mm. The thickness of soft products is measured by a thickness gauge, and the thickness of hard products is measured by a vernier caliper. Three points are uniformly measured along the length of the sample, and the reading is ** to 0.1 mm. The inner and outer diameters of the tubular product shall be measured at both ends of the specimen, each at 4 locations. The length was measured twice. Reading ** to 1mm. The measurement results of each size of the sample are averaged. Calculate the thickness (or wall thickness) and volume of the sample.

★ Place the sample on a water-repellent side tester (for a sample that has been treated with water repellency on one side, the water repellency of both sides should be measured separately. For plate products, the nozzle position should be adjusted according to the thickness of the sample to Meet the requirements of Figure 1. For tubular products, the inner surface should be downward, adjust the position of the spray head, so that the upper part of the sample is evenly sprayed), adjust the water flow to stabilize it at 1L / min, and continuously spray for lh, then Remove the sample, use the crepe paper to quickly absorb the water droplets on the surface, and immediately weigh the sample mass m2.

The sample of the tubular product is 300mm long, the cross section is semi-circular or fan-shaped, and the wall thickness is the original wall thickness of the product. Samples should be prepared as representative as possible, and samples should not be taken from areas with wrinkles or surface damage. Skins should be removed from foam plastic products.
