       外墙外保温体系的组成与基本构造情况在不同的外保温体系中，其材料、构造和施工工艺各有一定的差别。有代表性的基本构造有两种:其一，由饰面层、含有加强网布的抹灰层、b1级挤塑板保温层、粘结层及基底等由外至内依次组成;其二，由表面装饰层、有钢丝网加强的抹灰层、岩棉板、粘结层及基层，另加固定件，依次由外至内组成。
　　保温层应采用高效保温材料，导热系数小于0.05kw/mk，吸湿率低、粘结性能好、收缩率小的产品。可选用膨胀型聚苯乙烯板、岩棉板、玻璃棉毡以及超轻保温浆料等，其中，阻燃级膨胀型聚苯乙烯板应用普遍。
　　保温层的固定有三种做法:粘结法、钉固法和混合法。混合法是以粘结为主，兼以钉固;或以钉固为主，兼以枯结。粘结材料多种多样。有拌制好的胶浆，有粉状材料、有需现场拌制和配料的粘结材料等。钉固机械件，一般采用由不锈钢、尼龙或聚内烯制成的膨胀螺栓或预埋锚固筋，国内多采用经过防锈处理的钢制膨胀螺栓。

   Composition and the basic structure of the external wall thermal insulation system in different external thermal insulation system, its material, structure and construction process each has certain difference. Typical basic structure has two kinds: first, the fabric is intensified by the act the role of surface layer, containing the plaster layer of b1 level, extruded board insulation layer, adhesive layer and substrate from outside to inside in turn; Second, by the surface decoration layer, steel wire reinforced plaster, rock wool board, bonding layer, and at the grass-roots level, plus a fixed piece, in turn, from outside to inside.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    Insulation layer should use efficient thermal insulation material, heat conduction coefficient is less than 0.05 kw/mk, low moisture absorption rate, good bonding performance, small shrinkage rate of the product. Can choose inflating polystyrene board, rock wool board, glass cotton blanket and lightweight insulation slurry, etc., among them, the flame retardant grade inflating polystyrene board applied widely.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
   There are three kinds of thermal insulation layer of fixed: bonding method, nail fixation method and hybrid method. The hybrid method based on bond is given priority to, and screw fixation; Or is given priority to with screw fixation, and to dry. Bonding material is varied. Mixing good glue paste, powder materials, have to be on-site mixing and batching of bonded materials. Nailed machinery parts, general use made of stainless steel, nylon or poly olefin bolts or pre-embedded anchoring reinforcement, many domestic antirust processing steel bolts.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
