Description

一种用于低温储罐的绝热保冷保温板及其安装方法Heat-insulating cold-preserving and heat-preserving board for low-temperature storage tank and installation method thereof 技术领域Technical field
本发明涉及低温储罐外壁的保温材料，具体涉及一种用于低温储罐的绝热保冷保温板及其安装方法。The invention relates to a thermal insulation material for the outer wall of a low-temperature storage tank, in particular to a heat-insulating and cold-preserving and heat-preserving board for a low-temperature storage tank and an installation method thereof.
背景技术Background technique
在目前，市场上对于一些低温储罐以及燃料罐的保温，主要会采用聚氨酯喷泡和粘贴保温板的形式。At present, the insulation of some low-temperature storage tanks and fuel tanks on the market mainly adopts the form of polyurethane spray foam and pasted insulation boards.
聚氨酯喷泡会导致现场工作环境差，还需要培养大量的专业抢手，由于人为因素会导致现场材料存在较高的不稳定性，同时聚氨酯本身的材料性能伸缩性的限制，在储罐热胀冷缩的情况下，聚氨酯易发生开裂。Polyurethane foam spraying will lead to poor on-site working environment, and it is necessary to cultivate a large number of professional players. Due to human factors, there will be high instability of on-site materials. At the same time, the material performance of polyurethane itself is limited by the flexibility of the storage tank. In the case of shrinkage, polyurethane is prone to cracking.
粘贴保温板的形式，虽材料得到了较好的控制，可粘贴性能却会因为受到湿度，温度，施工工艺等因素而产生粘贴失效的问题，遇到储罐收缩量较大时，同样有保温开裂的可能性。The form of pasting insulation board, although the material is well controlled, the pasting performance will cause the problem of pasting failure due to factors such as humidity, temperature, construction technology and other factors. When the storage tank has a large shrinkage, it also has insulation Possibility of cracking.

The heat-preserving board includes a low-temperature laminate, a high-temperature laminate, a steel wire mesh and a protective skin arranged in layers, and the low-temperature laminates are adjacent to each other. Elastic thermal insulation materials are arranged on each side. The insulation system includes a low temperature layer, a high temperature layer, a steel mesh layer and a protective layer. Along the extension direction of the low temperature storage tank wall, multiple insulation boards are spliced to form the insulation system. Along the direction perpendicular to the low temperature storage tank wall, the inside of the low temperature layer is close to the low temperature The tank wall of the storage tank is set, the outside of the low temperature layer and the inside of the high temperature layer are connected by a steel mesh layer, the protective layer is set on the outside of the high temperature layer, and elastic insulation materials are set between two adjacent low temperature layer plates, and two adjacent high temperature layer plates The polyurethane spray bubble is set between, and the butyl tape covers the polyurethane spray bubble. The main heat preservation effect of this heat insulation and cold insulation board is low temperature laminate and high temperature laminate. The material used is commonly used polystyrene or polyurethane. When the number of boards is insufficient, the insulation effect and strength of the insulation board are not ideal.

Bonding low-temperature laminates, high-temperature laminates, steel wire mesh, and protective skins in sequence.

1)保温性能优异：采用预制的保温材料以及弹性保温材料，保温性能，稳定性和自身强度都高于现场喷泡和粘贴保温板这两种保温方式，避免了因为现场 人工因素以及环境因素而导致保温性能差异大的现象，使得保温系统整体密封性和强度都得到了很大的提升。1) Excellent thermal insulation performance: using prefabricated thermal insulation materials and elastic thermal insulation materials, thermal insulation performance, stability and self-strength are higher than the two thermal insulation methods of on-site foam spraying and pasting thermal insulation board, avoiding artificial factors and environmental factors on site. The phenomenon of large differences in insulation performance has greatly improved the overall sealing and strength of the insulation system.
2)形状设计优异：高温层四周形成斜口设计，便于最后聚氨酯泡沫填充时，使得聚氨酯泡沫能更完全的发泡，填满间隙。中间层以及低温层错层，形成楔口连接，加强了保温板之间的连接。2) Excellent shape design: An oblique design is formed around the high temperature layer to facilitate the final filling of the polyurethane foam, so that the polyurethane foam can be more completely foamed and fill the gap. The middle layer and the low-temperature stacking are staggered to form a wedge connection, which strengthens the connection between the insulation boards.
3)使用寿命长：相对于聚氨酯喷泡，保温板使用期限更为长久，保温板本身因为钢丝网而变得强度更好，又由于保温板之间有较好的弹性保温材料，又增加了整体保温的柔韧性，使得保温板不易被破坏。3) Long service life: Compared with polyurethane spray foam, the insulation board has a longer service life. The insulation board itself becomes stronger because of the steel mesh, and because of the better elastic insulation material between the insulation boards, it increases The flexibility of the overall insulation makes the insulation board not easy to be damaged.
4)使用范围广：可适用于各种不同形状，不同液化气体的低温储罐。4) Wide application range: It can be applied to cryogenic storage tanks of different shapes and different liquefied gases.
5)保温牢固：通过固定支座以机械连接的方式牢固的将保温板固定在液罐上，而保温板之间的钢丝和铆钉，使得整个保温系统成为一体，平分保温板所受的热胀冷缩的应力，防止保温系统因为应力集中而开裂，进一步加强了保温板系统的强度。5) Firm insulation: The insulation board is firmly fixed to the liquid tank by means of a mechanical connection through the fixed support, and the steel wire and rivets between the insulation boards make the entire insulation system into one, and the thermal expansion of the insulation board is equally divided. The stress of cold shrinkage prevents the insulation system from cracking due to stress concentration and further strengthens the insulation board system.
6)安装环境优异：对于环保要求越来越高的情况下，预制保温板可以大大的提高现场的工作环境。6) Excellent installation environment: In the case of higher and higher environmental protection requirements, prefabricated insulation boards can greatly improve the working environment on site.
7)安装简易，便捷：经过简单培训，普通工人即可理解操作步骤。减少对抢手的培训，减少人工成本。7) Easy and convenient installation: After simple training, ordinary workers can understand the operation steps. Reduce the training for the sought-after and reduce labor costs.

本发明的最佳实施方式The best mode of the invention
本发明保温板结构呈现错层形式，使得保温系统之间的连接更加的紧密。本发明中下中间层与低温层间需要充聚氨酯保温。本发明中采用固定支座，减少了安装时所需的部件，也加强了安装强度。本发明中一个固定支座固定一块保温板，结构强度高，而如专利CN109268673A的结构是通过丝杆和固定盘等同时固定两块保温板，结构强度较差。The insulation board structure of the present invention presents a staggered form, which makes the connection between the insulation systems closer. In the present invention, the lower middle layer and the low temperature layer need to be filled with polyurethane for heat preservation. The fixed support is adopted in the present invention, which reduces the parts required for installation and also strengthens the installation strength. In the present invention, a fixed support is used to fix a thermal insulation board, which has high structural strength. However, the structure of the patent CN109268673A uses a screw rod and a fixed plate to simultaneously fix two thermal insulation boards, which has poor structural strength.
