冷庫主要由圍護結構和制冷系統組成，圍護結構是用來阻止庫外的熱量傳到庫內，同時減少庫內的跑冷損失，使庫內溫度不會很快升高，圍護結構的好壞能直接影響制冷系統的制冷效果和耗電量，冷庫的圍護結構材料主要有夾芯聚氨脂板和夾芯聚苯板。
Cold storage is mainly composed of retaining structure and refrigeration system, palisade structure is used to prevent the heat outside the library to the house of the rolls, as well as reduce the rolls run cold loss, keep the temperature inside rises quickly, the stand or fall of palisade structure can directly affect the cooling effect of cooling system and power consumption, the palisade structure of the cold storage materials mainly have sandwich polyurethane board and sandwich of polystyrene.
選擇一款好的庫板，就是為你的冷庫建設安置了一道安全信心的屏障。冷庫內儲存的貨物的價值往往是冷庫造價的10倍以上，如果冷庫設計缺陷、施工質量差、材質不合格或者服務不到位，造成冷藏貨物變質甚至冷庫著火，其損失是很慘重的，所以從采購庫板這個最基礎的程序開始，務必就要做到一絲不茍，力求完善。
Choose a good library board, for your cold storage building settlement is a confidence in the safety barrier.

庫板，一般是由廠家預先生產的，具有固定的長度、寬度和厚度，高、中溫冷庫一般選用10厘米厚的板塊，低溫庫及凍結庫一般選用12厘米或15厘米厚的板塊；
Library board, is commonly produced by manufacturers in advance, has the fixed length, width and thickness of high and medium temperature cold storage generally selected 10 centimeters thick plate, low temperature library and freeze library generally choose 12 cm or 15 cm thick plate;
所以食品冷庫如果不是預定的庫板，采購時就要注意庫板的密度和鋼板的厚度，正規廠家鋼板厚度一般要在0.4MM以上，冷庫庫板發泡密度按照國家標準是每立方米在38KG～40KG/立方米。
So if not scheduled library board, purchasing will pay attention to the density of base plate and the thickness of the steel plate, steel plate thickness will make the 0.4 MM above normal manufacturer, cold storage library board foam density according to the national standard is per cubic meter in 38 kg ~ 40 kg/m3.
采購庫板比不得采購其他的日常生活用品，一旦出現紕漏，就會影響整個冷庫工程的建設，所以如果是采購大批量的庫板最好能先找到一家值得信賴的企業，考察該企業的產品之后再決定是否采購。
Purchase library than can not purchase other daily necessities, once appear, will influence the whole construction of the cold storage, so if you are purchasing large quantities of library board it is best to find a trustworthy company, first inspection of the enterprise product before deciding whether to purchase.
