聚乙烯资料黑夹克保温管。用高压发泡机在钢管与外护层之间构成的空腔中一次性注入硬质聚氨酯泡沫塑料原液而成，再用聚乙烯停止钢管外表的处置，构成外层的维护层。聚乙烯外壳直埋保温管高密度聚乙烯保温管直埋式预制保温管由保送介质的钢管、聚氨酯硬质泡沫保温层和高密度聚已烯外套管严密分离而成，直埋保温管主要用于城镇集中供热管网，石油保送管线，高寒地域输水管线及产区工业管道工程。由于聚氨酯硬质泡沫保温层严密地粘结在钢管外皮，隔绝了空气和水的渗入，能起到良好的防腐作用。同时它的发泡孔都是闭合的，吸水性很小。高密度聚乙烯外壳、玻璃钢外壳均具有良好的防腐、绝缘和机械性能。

Polyethylene material black jacket insulation pipe. A high-pressure foaming machine is used to inject rigid polyurethane foam plastics into the cavity formed between the steel pipe and the outer cover at one time, and then polyethylene is used to stop the disposal of the outer surface of the steel pipe to form the outermost maintenance layer. Polyethylene buried directly buried heat insulation pipes, high density polyethylene insulation pipes, directly buried precast insulation pipes are tightly separated from steel pipes, polyurethane rigid foam insulation layer and high density polyethylenes coat pipe. Directly buried thermal insulation pipes are mainly used for urban central heating network, oil delivery pipeline, high cold area water delivery pipeline and industrial pipeline project in production area. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the infiltration of air and water can be isolated, and good anticorrosion effect can be achieved. At the same time, its foaming holes are closed and its water absorption is very small. High density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical properties.

1.聚氨酯硬泡具有一材多用的功用，同时具备保温、防水、隔音、吸振等诸多功用。

1. Polyurethane rigid foam has many functions, such as heat preservation, waterproof, sound insulation, vibration absorption and so on.

2.黑夹克保温钢管保温性能杰出，是目前国内一切建材中导热系数低(≤0.024)、热阻值高的保温资料，导热系数仅为EPS发泡聚苯板的一半。

2. Black jacket insulating steel pipe has excellent thermal insulation performance. It is the thermal insulation material with low thermal conductivity (<0.024) and high thermal resistance in all domestic building materials, and its thermal conductivity is only half of EPS foamed polystyrene board.

3.黑夹克保温钢管聚氨酯硬泡体连续致密的表皮和近于100%的高强度互联壁闭孔，具有理想的不透水性。采用喷涂法施工到达防水保温层连续无接缝，构成无缝屋盖和整体外墙保温壳体，防水抗渗性能优良。

3. The polyurethane rigid foam of the black jacket insulating steel pipe has continuous and dense skin and nearly 100% high strength interconnected wall closure, which has ideal impermeability. Spraying method is adopted to construct continuous seamless waterproof insulation layer, which forms seamless roof and whole external wall insulation shell. The waterproof and impermeability performance is excellent.

4.的自黏性能(无需任何中间黏结资料),与屋面及外墙黏结结实，抗风揭和抗负风压性能良好；整体喷涂施工，完整消弭“热节”和“冷桥”;柔性突变技术可有效阻止防水层开裂；机械化作业、自动配料、质量均一、施工快、周期短。

4. Super self-adhesive performance (without any intermediate bonding data), and the roof and external wall bonding, wind exposure and negative wind pressure resistance performance is good; integral spraying construction, complete elimination of "hot spot" and "cold bridge"; flexible mutation technology can effectively prevent the cracking of waterproof layer; mechanized operation, automatic ingredients, uniform quality, fast construction, short cycle.

5.化学性质稳定，运用寿命长，对四周环境不构成污染；离明火自熄，且熄灭时只炭化不滴淌，炭化层尺寸和外形根本不变，能有效隔断空气的进入，阻止火势的蔓延，防火平安性能好。 作为目前独一的保温防水一体化新型建材，聚氨酯硬泡保温资料在国内建筑业的应用尚处于初始阶段。可喜的是，为加快建筑保温资料的改造，促进聚氨酯硬泡在建筑范畴的推行应用，建立部特地成立了“聚氨酯建筑应用工作组”,以推进聚氨酯硬泡保温防水资料在国内建筑行业的应用。

5. The chemical property is stable, the service life is long, and it does not pollute the surrounding environment; the open flame extinguishes itself, and only carbonization does not drip when it is extinguished. The size and shape of the carbonization layer are basically unchanged, which can effectively cut off the entry of air, prevent the spread of fire, and have good fire safety performance. As the only new building material with integrated thermal insulation and waterproofing, the application of polyurethane rigid foam thermal insulation materials in domestic construction industry is still in its initial stage. Fortunately, in order to speed up the transformation of building thermal insulation materials and promote the application of polyurethane rigid foam in the field of building energy saving, the Ministry has set up a special "working group on polyurethane building energy saving applications" to promote the application of polyurethane rigid foam thermal insulation and waterproofing materials in the domestic building energy saving industry.
