1.黑夹克保温管的隔热层是否偏心,即聚氨酯隔热层与钢管不同,隔热厚度不均匀,严重的人会通过外部塑料软化而受损。
1. Whether the heat insulation layer of black jacket insulation pipe is eccentric, that is, polyurethane insulation layer is different from steel pipe, and the insulation thickness is uneven, and serious people will be damaged by external plastic softening.
2.黑色夹克保温管的使用在运输和安装过程中容易受损,沉没后地面深度不足,或者上部土壤和道路松软,装载车辆被践踏后受损。
2. The use of black jacket insulation pipe is easy to be damaged in the process of transportation and installation. After sinking, the ground depth is insufficient, or the upper soil and road are soft, and the loading vehicle is trampled.
3、黑色夹克保温管介面处理,在管道安装过程中,两个管道焊接不能紧密渗透,或在“补入”过程中不能正常工作,外部污水渗透保温层等破坏。
3. In the process of pipeline installation, the welding of the two pipes can't penetrate tightly, or they can't work normally in the process of "filling", and the external sewage can't penetrate the insulation layer.

4、如果经常发现使用夹克管的选材(如杂物回收塑料),挤压成型的塑料管就不能充分塑化,外部管就会劣化。聚氨酯保温管密度低,强度低,在处理过程中受损,系统中玻璃酸太高,腐蚀在钢管外墙等。
4. If it is often found that the material of jacket pipe (such as waste recycling plastic) is used, the extruded plastic pipe can not be fully plasticized, and the external pipe will deteriorate. Polyurethane insulation pipe has low density and low strength, which is damaged in the process of treatment. The glass acid in the system is too high, and corrosion occurs on the outer wall of steel pipe.
聚氨酯黑夹克保温管高温预制直埋保温管是一种保温性能好,加安全可靠,工程造价低的直埋预制保温管。有效的解决了城镇集中供热中130C - 600C高温输热用预制直埋保温管的保温、滑动润滑和管端的防水问题。高温预制直埋保温管不仅具有传统地沟和架空敷设管道难以比拟的先进技术、实用性能,而且还具有显著的社会效益和经济效益,也是供热节能的有力措施。高温预制直埋保温管由于聚氨酯硬质泡沫保温层紧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。聚氨酯保温管高密度外壳、聚氨酯保温管玻璃钢外壳均具有良好的防腐、绝缘和机械性能。
Polyurethane black jacket thermal insulation pipe is a kind of direct buried insulation pipe with good thermal insulation performance, safety and reliability, and low engineering cost. It can effectively solve the problems of heat preservation, sliding lubrication and waterproof of pipe ends of the prefabricated directly buried insulation pipe for 130c - 600C high temperature heat transmission in urban central heating. High temperature prefabricated directly buried insulation pipe not only has the advanced technology and practical performance that traditional trench and overhead laying pipeline can't match, but also has significant social and economic benefits, which is also a powerful measure of heating and energy saving. The high temperature prefabricated directly buried insulation pipe is tightly adhered to the outer skin of the steel pipe due to the rigid polyurethane foam insulation layer, and the air and water infiltration are separated from the insulation layer, which can play a good anticorrosive role. At the same time, its foam cells are closed, water absorption is very small. The high density shell of polyurethane insulation pipe and the glass fiber reinforced plastic shell of polyurethane insulation pipe have good anticorrosion, insulation and mechanical properties.
聚氨酯保温管泡沫强度小,泡沫柔软现象是黑白比例失衡造成的,适当增加石墨的比例即可(1: 1-1.05)。请注意,黑材料的比例不要太大。否则,泡沫酥脆,也会影响泡沫性能。聚氨酯黑色夹克孵化器预制孵化器是保温性能好、安全可靠、工程成本低的直卖式孵化器。
PU foam insulation foam strength is small, soft foam phenomenon is caused by imbalance between black and white ratio, appropriate increase the proportion of graphite can (1: 1-1.05). Please note that the proportion of black material should not be too large. Otherwise, the foam crisp will also affect the performance of the foam. Polyurethane black jacket incubator prefabrication incubator is a direct selling incubator with good heat preservation performance, safety and reliability, and low engineering cost.
