七湿材料的干燥 1.湿材料的干燥含水份的材料称为湿材料。水份可能呈固态、液态或汽态存在于材料中。以下是計算材料湿度的几个基本公式: G_M——絕对干燥材料的重量,公斤; G——湿材料的重量,公斤; G_Ж——材料中所含水份的重量,公斤; G=G_M+G_Ж。(1) 材料湿度的表示方法有兩种:材料的含水量与絕对干燥材料重量的比(以百分数表示)称为材料的絕对湿度;材料的含水量与湿材料重量的比(以百分数表示)称为材料的相对湿度。以ω_c表示材料的絕对湿度,ω表示材料的相对湿度,則
Drying of a Seven-Wet Material 1. A dry moisture-containing material of a wet material is called a wet material. Water may be present in the material in a solid, liquid, or vapor state. The following are some basic formulas for calculating the moisture content of a material: G_M – the weight of the absolutely dry material, in kilograms; G – the weight of the wet material, in kilograms; G_Ж – the weight of the moisture content in the material, in kilograms; G=G_M +G_Ж. (1) There are two ways to express the humidity of a material: the ratio of the moisture content of the material to the absolute dry material weight (expressed in percent) is the absolute humidity of the material; the ratio of the water content of the material to the weight of the wet material (in percent Indicates) The relative humidity of the material. The absolute humidity of the material is represented by ω_c, and the relative humidity of the material is represented by ω.
