在农业科学研究单位,进行生物试验时,需要有保温保湿的实验室。蛭石粉恒温室既能将室内的温度在短时间内升到目的温度,又能在短时间内保持室内温度相对稳定,保温节能,耗能少,设备简单,使用方便。蛭石是云母族的一种矿石,经过高温焙烧后,体积能增大10～20倍,形成多孔层状颗粒,这种颗粒叫做蛭石粉。蛭石粉及加工成的蛭石砖,其导热系数很低,小于0.04千卡/米·时,是一种理想的保温材料。一、修建方法蛭石粉恒温室的建筑可根据科学实验和养蚕规模,可大可小。我们修建面积一般是210×213厘米,每间使用面积为3.14平方米,空间体积为7.14立方米。1.墙壁施工用楞木作为小房间的框架,框架的里、外面钉上灰条,再抹上麻刀石灰,形成空心墙,空心距为18～20厘米。墙高为270厘米,墙厚为25厘米,中间充填18～20
In agricultural science research units, biological tests, the need for insulation moisturizing laboratory. The vermiculite powder thermostatic chamber can not only raise the indoor temperature to the target temperature within a short time, but also keep the indoor temperature relatively stable in a short period of time, save energy and heat, save energy, and have simple equipment and convenient use. Vermiculite mica is a kind of ore, after calcination at high temperature, the volume can increase 10 to 20 times, the formation of porous layered particles, this kind of particles is called vermiculite. Vermiculite powder and processed into vermiculite brick, the thermal conductivity is very low, less than 0.04 kcal / m ·, is an ideal insulation material. First, the construction method Vermiculite thermostat chamber construction according to scientific experiments and sericulture scale, can be varied. Our construction area is generally 210 × 213 cm, each use area of 3.14 square meters, the volume of space is 7.14 cubic meters. 1. Wall construction As a small room with a wooden frame, the frame inside and outside the nail on the gray bar, and then smear slap lime, forming a hollow wall, the hollow distance of 18 to 20 cm. Wall height of 270 cm, wall thickness of 25 cm, the middle filling 18 to 20
