在進行集裝箱活動房維護結(jié)構(gòu)保溫設(shè),要結(jié)合當?shù)氐臍夂驐l件、集裝箱活動房的結(jié)構(gòu)特點、多式聯(lián)運條件以及經(jīng)濟性方面的要求,考慮保溫形式(即采用外保溫還是內(nèi)保溫),通過較小總熱阻的計算,確保保溫構(gòu)造與厚度。對夏熱冬冷地區(qū),既要考慮建筑外面護結(jié)構(gòu)的隔熱,又要考慮冬季建筑外面護結(jié)構(gòu)的保溫。
In the thermal insulation design of the maintenance structure of the container mobile room, the local climate conditions, the structural characteristics of the container mobile room, the multimodal transportation conditions and the economic requirements should be considered. The insulation form (i.e. external insulation or internal insulation) should be considered, and the insulation structure and thickness should be ensured through the calculation of small total thermal resistance. In hot summer and cold winter area, it is necessary to consider not only the thermal insulation of the external protective structure of the building, but also the insulation of the external protective structure of the building in winter.
因多式聯(lián)運過程中的起吊、堆碼、栓固等要求,以及港口、堆場作業(yè)條件和海陸運輸環(huán)境、集裝箱活動房圍護結(jié)構(gòu)通常采用內(nèi)保溫形式。
Due to the requirements of lifting, stacking and fastening in the process of multimodal transportation, as well as the working conditions of ports and storage yards, the sea and land transportation environment, and the enclosure structure of container mobile room, the internal thermal insulation form is usually adopted.
盡可能采用熱導(dǎo)系數(shù)小保溫隔熱材料,以減少保溫層的厚度,提高室內(nèi)使用面積。
Thermal insulation materials with small thermal conductivity should be used as far as possible to reduce the thickness of thermal insulation layer and improve the indoor use area.
保溫隔熱材料按材質(zhì)可分為無機保溫隔熱材料、保溫隔熱材料和金屬絕熱材料三大類;按形態(tài)又可分為纖維狀保溫隔熱材料、多孔(微孔、氣泡)狀保溫隔熱材料、層狀保溫隔熱材料等幾種。
Thermal insulation materials can be divided into inorganic thermal insulation materials, thermal insulation materials and metal thermal insulation materials according to the materials; according to the form, they can be divided into fibrous thermal insulation materials, porous (microporous, bubble) thermal insulation materials, layered thermal insulation materials and so on.
保溫隔熱材料的性能取決于材料的熱導(dǎo)系數(shù),熱導(dǎo)系數(shù)愈小,集裝箱活動房保溫隔熱的性能則愈好。保溫隔熱材料的熱導(dǎo)系數(shù)與其成分、表觀密度、內(nèi)部結(jié)構(gòu)以及傳熱時的平均溫度和材料的含水率有關(guān)。
The performance of thermal insulation material depends on the thermal conductivity of the material. The smaller the thermal conductivity coefficient is, the better the thermal insulation performance of container mobile room is. The thermal conductivity of thermal insulation materials is related to its composition, apparent density, internal structure, average temperature during heat transfer and moisture content of materials.
在集裝箱活動房建筑圍護結(jié)構(gòu)中常用的絕熱保溫材料有模塑聚苯乙烯泡沫塑料、擠塑聚苯乙烯泡沫塑料、硬質(zhì)聚氨酯泡沫塑料、巖棉板、玻璃棉等。
Thermal insulation materials commonly used in containerized building envelope include molded polystyrene foam, extruded polystyrene foam, rigid polyurethane foam, rock wool board, glass wool, etc.
