High-strength heat-insulation pipe shell and preparation method
The invention relates to an accessory matched with a pipeline, in particular to a high-strength heat insulation pipe shell and a preparation method. The high-strength heat insulation pipe shell is mainly formed by mixing vitrified micro bubbles, light ceramsite, silica fume, anti-cracking fibers and an aluminate gelling agent according to the weight percentage of 20-24: 40-45: 3-5: 3-4: 26-30 and then performing curing. The preparation method comprises the following steps: (1) uniformly mixing the vitrified micro bubbles, the light ceramsite, the silica fume, the anti-cracking fibers and the aluminate gelling agent according to a ratio in a dry manner; 2) adding water for wet mixing to obtain a mixture; (3) placing the mixture in a mold, enabling a vibrating bar to vibrate, and enabling the outer surface to be flattened; 4) performing demolding and then performing stable curing to obtain the product. The composite material has the advantages of light weight, higher strength, lower heat conductivity coefficient and better vibration resistance and crack resistance. The cost is low, the process is simple, and industrial production is easy. The heat preservation and insulation support is used for heat distribution pipelines and gravity thermal equipment of petrochemical engineering, thermal power plants, pharmacy and heating engineering.
本发明涉及一种管道配套用附件，具体涉及一种高强度隔热保温管壳及制备方法。高强度隔热保温管壳，主要由玻化微珠、轻质陶粒、微硅粉、抗裂纤维、铝酸盐胶凝剂按重量百分比20‑24：40‑45：3‑5：3‑4：26‑30适量水混合后固化而成。本发明制备方法，包括以下步骤：1)将玻化微珠、轻质陶粒、微硅粉、抗裂纤维、铝酸盐胶凝剂按配比干混均匀；2)加入水湿混，得混合料；3)将混合料盛入模具，振动棒振动，外表面修平；4)脱模后稳定固化即得产品。具有重量轻、较高的强度、较低的导热系数、较好的抗振抗裂性。成本低，工艺简单，易于产业化生产。用于石油化工、热电厂、制药、取暖工程的热力管道及重力热设备的保温隔热支撑。
