Ji'nan Engineering Plank house is a house that is lapped up with color steel sandwich panels. The general engineering activity board room is made up of two layers of colored steel plates and core materials for continuous moulding of polystyrene, which is commonly known as foam board. This kind of movable board house is common, and it is mainly used in temporary dormitory or temporary office, farm market, newsstand, warehouse, etc.

一種就是以巖棉為材料的彩鋼夾芯板，這種夾芯板相對(duì)聚苯乙烯夾芯板來(lái)說(shuō)稍貴，但保溫效果好，防火性能好，隔音效果也好，使用范圍也廣，另外一種是以硬質(zhì)聚氨酯泡沫為芯材的新型保溫材料，這種保溫板稱為聚氨酯夾芯板，

One is the color steel sandwich panel with rock wool as the material. The sandwich panel is slightly more expensive than the polystyrene sandwich panel, but its heat preservation effect is good, its fireproof performance is good, its sound insulation effect is good, and its application range is wide. Another kind is a new type of thermal insulation material with rigid polyurethane foam as core material, which is called polyurethane sandwich panel.

保溫板的特點(diǎn)：不燃、防潮、防蟲蛀、隔音、質(zhì)輕、干濕不會(huì)變形、保溫效果，并且可釘、可鋸、施工簡(jiǎn)單方便，并且可以重復(fù)循環(huán)使用，而且該夾芯板不會(huì)出現(xiàn)裂紋、折斷，且具有耐磨、表面質(zhì)量平整光滑效果。在超低溫下使用收縮小、不脆化，被廣泛應(yīng)用于簡(jiǎn)易活動(dòng)房的屋面、墻體、空氣潔凈室的吊頂與隔斷、廠房、倉(cāng)庫(kù)等大型建筑的屋面，更為適合建造冷庫(kù)。如果活動(dòng)板房采用這種夾芯板為搭接板材保溫效果非常好，就是較貴。

The characteristics of the insulation board: non combustible, moisture-proof, mothproof, sound insulation, light weight, dry and wet will not deform, thermal insulation effect, and can be nailed, sawn, simple and convenient construction, and can be recycled, and the sandwich panel will not crack, break, and has wear-resistant, smooth surface quality effect. It is widely used in roof and wall of simple movable room, ceiling and partition of air clean room, roof of high-grade workshop, warehouse and other large-scale buildings. It is most suitable for building cold storage. If this kind of sandwich panel is used in the movable board room, the insulation effect is very good, that is, the price is more expensive.
