    济南通风管道的绝热处理,A. 通风管道及部件绝热工程
    A. ventilation pipe and component insulation engineering
    ① 根据通风管道的断面尺寸和所处的部位确定绝热固定钉的数量。
    According to the section size and the location of the ventilation pipe, the quantity of the insulated fixing nails is determined.
    ② 确定固定钉位置后░,先将通风管道壁上的尘土•●、油垢擦净░,再将粘接剂分别涂抹在通风管道壁面和保温钉的粘接面上░,稍后再将其粘接在一起。固定钉粘牢后应待12~24h后再覆铺绝热材料。
    The determination of position fixing nail, the ventilation pipe on the wall of dust, grease wipe, and then adhesive were coated in the ventilation pipe wall and insulation nail on the adhesive surface, later the bonding together. After the cement nail should be 12~24h after coating insulation material shop.
    ③ 绝热材料下料要准确░,套裁下料░,切割面要平齐░,搭接处不要有缝隙。纵横缝错开░,小块材料应尽量用于通风管道上平面中间部位。

    The insulation material should be accurate, cutting materials, cutting surface should be leveled at the joint gap is not. The staggered joints should be staggered and the small pieces of material should be used as far as possible on the middle plane of the ventilation pipe.

    济南通风管道明装矩形通风管道绝热应在四角加设镀锌钢板包角░,并用镀锌铁丝固定或打包带卡紧。
    The rectangular ventilation pipe shall be insulated at four angles with galvanized steel sheet and fastened with galvanized wire or packed with strap.
    B. 制冷•●、制热管道绝热工程
    B. refrigeration and heating pipe insulation engineering
    ①聚苯乙烯泡沫塑料瓦壳绝热结构。
    Thermal insulation structure of polystyrene foam tile shell.
    a. 首先将保温瓦合扣在管道处面░,每隔300~350mm用φ1.2mm镀锌铁丝绑扎牢固(铁丝断头必须嵌入保温瓦内)░,瓦与瓦之间的缝隙用石棉硅藻土填补抹平。
    A. first insulation tile buckle in the pipeline at the surface, every 300~350mm with 1.2mm diameter galvanized wire (wire breakage must be firmly embedded in the insulation tile), gap between tiles with asbestos diatomite fill out.
    b. 保温瓦外包一道塑料薄膜░,再包一道玻璃丝布。包扎时将玻璃丝布裁成幅宽在200~300mm░,缠绕搭接宽度为50~80mm。
    B. insulation tile outsourcing a plastic film, then wrapped in a glass cloth. When dressing will cut glass cloth width at 200~300mm, width of 50~80mm lap winding.
    c. 玻璃丝布外涂两道调合漆。
    C. glass cloth coated with two mixed paint.
    ② 毡状材料绝热结构。
    Insulation structure of felt material.
    a. 管道外用保温毡捆扎░,捆扎时注意搭接边要贴紧。绝热层外每隔300~350mm用φ1.2mm镀锌铁丝绑扎。包完第一层后░,再包第二层░,层数根据所需厚度决定。多层捆扎要纵横缝隙交错•●、填满并密封严格。
    A. pipe external insulation felt tied, tied to pay attention to the edge of the lap should be tight. 300~350mm 1.2mm galvanized wire binding at intervals outside the insulation. After wrapping the first layer, wrap the second layer and determine the number of plies depending on the thickness required. Multi layer strapping should be vertical and horizontal, staggered, filled and sealed tightly.
    b.济南通风管道 绝热层外包一层沥青油毡░,接缝处要搭接严密░,并用φ1.2mm镀锌铁丝绑扎牢固。
    B. insulation layer is wrapped with asphalt felt. The joints shall be lapped tightly and bound with 1.2mm galvanized iron wire.
    c. 油毡外包玻璃丝布░,将玻璃丝布裁成幅宽在200~300mm░,缠绕搭接宽度为50~80mm。外表面涂刷两道调合漆。
    C. felt outsourcing glass cloth, glass cloth cut width in 200~300mm, width of 50~80mm lap winding. Paint two blending paint on the surface.
