华美橡塑保温质量通病主要表现为胶水涂刷不均匀,橡塑保温材料粘接不严密,橡塑保温材料的厚度选用不正确以及外观型式不统一,型式不美观等。在施工中有如下几个主要质量问题:
Common problems of Huamei rubber and plastic insulation quality are mainly manifested in uneven painting of glue, untight bonding of rubber and plastic insulation materials, incorrect selection of thickness of rubber and plastic insulation materials, inconsistent appearance type, and ugly type. There are several main quality problems during construction:
(1)保温层与木托粘接不严密。施工中,因工人保温层长度测量不准确,工人施工时常将保温材料拉长后粘接。由于材料本身有弹性,拉伸后即会收缩,时间长了,就出现了保温材料与木托粘接处开胶的现象,这是保温中常见的质量问题之—。
(1) The insulation layer is not tightly bonded with the wooden support. During the construction, due to the inaccurate measurement of the length of the thermal insulation layer, workers often stretch the thermal insulation materials before bonding. As the material itself is elastic, it will shrink after stretching. Over a long period of time, the adhesive between the thermal insulation material and the wooden base will open, which is one of the common quality problems in thermal insulation.
防治措施:在下料和粘接过程中不准拉伸材料,同时要求在木托两侧和保温材料截面上都要涂刷胶水,胶水涂刷的要均匀饱满;木托要选用规则的,如果木托断裂成数块,就要换掉,防止因冷桥产生结露现象。
Prevention and control measures: do not stretch the material during blanking and bonding. At the same time, it is required to apply glue on both sides of the wooden bracket and the section of the thermal insulation material, and the glue should be applied evenly and fully; The wooden support shall be regular. If the wooden support breaks into several pieces, it shall be replaced to prevent condensation due to cold bridge.
(2)保温材料之间粘接不严密。保温材料之间的粘接比较常见,特别是在水平管上方和立管的侧面保温材料的粘接缝较长,很容易出现粘接不牢的现象。这主要是材料在切割过程中截面不平整、胶涂刷不均匀造成的,这也是保温中常见的质量问题之一。
(2) The bonding between insulation materials is not tight. Bonding between thermal insulation materials is common, especially when the bonding joint of thermal insulation materials above the horizontal pipe and on the side of the riser is long, which is easy to lead to poor bonding. This is mainly caused by the uneven cross section and uneven coating of glue during the cutting process, which is also one of the common quality problems in thermal insulation.
防治措施:要求施工人员在下料的过程中要使用直尺,不能徒手下料,涂刷胶水时要求均匀,粘接时要从一侧开始逐步向另一侧用力挤压,保证材料的切割面都能受力粘接牢固。
Prevention and control measures: the construction personnel are required to use a ruler in the process of blanking, and cannot blanking with bare hands. The application of glue should be uniform, and the adhesive should be forced from one side to the other gradually, so as to ensure that the cutting surface of the material can be firmly bonded by force.
(3)弯头处开胶。管道保温时一般要求把保温层接缝放在管道上方,而在管道的弯头上方经常出现保温层开裂现象,致使局部保温层过薄,造成凝结水结露。
(3) Glue is opened at the elbow. During pipeline thermal insulation, it is generally required to place the joint of thermal insulation layer above the pipeline. However, the thermal insulation layer often cracks above the elbow of the pipeline, causing local thermal insulation layer to be too thin, causing condensate condensation.
防治措施:要求施工人员在做弯头保温时不能只根据估计的尺寸下料,要用软皮尺准确量取尺寸;所下料的截面要平整;在管道弯头局部受力大的地方多涂抹胶水。
Prevention and control measures: the construction personnel are required not to cut materials only according to the estimated size when doing elbow insulation, but to accurately measure the size with a soft tape; The section of blanking shall be flat; Glue shall be applied at the places where the local stress of the pipe elbow is large.
对弯头保温时,尽量采用直接弯管保温,即保温层粘接缝顺着管道方向,而不采用切割马蹄型分多次粘接来找补弧度的方法。这样可省去大量的人力时间和材料,还能保证保温质量,同时外观上也较后者美观。
For elbow insulation, direct elbow insulation shall be adopted as far as possible, that is, the bonding joint of insulation layer shall be along the direction of the pipeline, instead of the method of cutting horseshoe type and bonding several times to repair the radian. This can save a lot of labor time and materials, and also ensure the quality of insulation, while the appearance is more beautiful than the latter.
