Li Yibin (Daqing Petroleum Administration Group) Liu Xuehui (Daqing Oilfield Engineering Co., Ltd.) (The column host introduces a large number of bubbles, C1 helps to reduce the material, thermal conductivity is governed by the test. WishingHouse.Allrights kind of lightweight and efficient insulation energy-saving materials, it can Insulation under the condition of large temperature change, and the heat flow loss value is small, the thermal conductivity of the structure is low, and the thickness of the thermal insulation layer can be reduced to more than 50% of the traditional thermal insulation material, which not only meets the design requirements of the thermal insulation body but also reduces the extra load of the equipment. It is an ideal green environmental protection and energy saving product.

1 Screening of selected fiber materials for the main raw materials. In order to meet the requirements of the ratio, various fiber materials were selected in the test, such as rock wool, mineral wool, glass wool, chrysotile, aluminum silicate, sepiolite, etc., and finally three inorganic fibers were determined. The raw materials for this test, namely natural chrysotile, aluminum silicate and sepiolite.

After the chrysotile and aluminum silicate fibers are fully released, they all become monofilament. These fibers have a large aspect ratio and have good mechanical strength. After sufficient agitation, they are three-dimensionally chaotic in the slurry. To the distribution, this is extremely advantageous for the formation of the structure. The horizontally distributed fibers provide a good tensile strength to the insulating profile, while the vertical or inclined fibrous binder and adsorbent, under the action of sepiolite, provide the structure as a whole with good stability. In addition, since the selected fiber materials have a certain elasticity, the produced heat insulating profiles have a high compression recovery rate.

Screening of aggregates. In order to improve the thermal stability of the slurry structure of the thermal insulation profile, reduce the density, improve the thermal insulation effect, and contribute to the formation of the structure, lightweight materials such as expanded perlite, vermiculite, hollow microspheres, and silicon are generally used in the ratio. For diatomaceous earth, etc., silicate materials with small bulk density, light weight and good performance are used as aggregates.

Part of the binder is added during the beating process. One is to increase the bonding strength of the fiber and other materials to improve the elasticity; the other is to increase the high and low temperature adhesion and non-combustibility of the material.

(4) Screening of blowing agent. The gas is introduced by a high-speed agitator mainly in the process of slurry production to achieve foaming.

2 Application scope and construction characteristics Waterproof and heat preservation composite silicate profile is a lightweight and efficient insulation energy-saving material, which can be widely used in petroleum, chemical, electric power, metallurgy, national defense, textile, transportation, construction and other departments. Thermal pipelines and thermal equipment. Such as kiln, boiler, flue duct, refrigeration equipment, towers, tanks and other industrial equipment.

(2) Insulation profiles do not cause itching like rock wool, mineral wool or fiberglass products, and do not affect the hygiene of equipment.

(4) The material is light, the heat preservation effect is good, and the heat loss of other insulation materials larger than the density and thermal conductivity is smaller.

3 innovation points and technological advancement innovation points. The innovation of the product researched in this test belongs to the hydrophobic product; the second is that the price is lower than the similar product; the third is the thin insulation layer during construction, no other auxiliary materials, the simple construction can reduce the extra load of the equipment, beautiful, non-toxic, No pollution, long service life.

Technological advancement. The heat preservation profile has the advantages of small density, light weight, good strength, small thermal conductivity and no pollution, and is a hydrophobic product. The production process is simple, the cost is low, and the construction work efficiency can be increased by 3 to 4 times. Field application shows that the insulation effect meets the maximum allowable heat loss value required for the perennial operating conditions given in Table A1 of GBU74-87.

Analysis of economic benefits and social benefits. The cost of the project is estimated to be 350~500 yuan/4 through matching and trial production cost. The cost is about 10% lower than that of rock wool board and other mineral wool insulation materials, which is lower than the cost of silicate composite thermal insulation coatings of similar products. 15%.
