Mortar used for building firewall in petroleum industry and its construction process

Abstract

The invention relates to a mortar used for building a firewall in petroleum industry, which comprises the following ingredient by mass percentage 15-25% of alumina cement, 2-5% of powdery fire clay, 15-25% of bauxite particle, 50-60 parts of dry sand and the balance of water. The mortar of the invention is capable of effectively raising the intensity of the mortar at early stage, increasing the bonding performance of the mortar and firebricks, ensuring the intensity of the mortar after high temperature calcining, and enhancing the corrosivity resistance of sulfate; and invention has the advantages that the preparation process and the construction process are convenient to operate, the construction period can not be prolonged, no other side-effect and hidden trouble can be generated, and is suitable for projects with short construction period and immediate usage, thereby the construction risk can be effectively reduced and the hidden trouble can be eliminated, compared with a traditional process, the cost of the invention is lower.

Description

technical field [0001] The invention relates to a mortar used for building refractory bricks and a construction process thereof, in particular to a mortar used for building a firewall in the oil industry and a construction process thereof. Background technique [0002] Refractory cement is a powder made of bauxite clinker and a binder. It is used as a filling material for the gap between refractory bricks. Refractory cement is also called bauxite cement. It is water with low alkalinity aluminate as the main mineral The hard material is an unshaped refractory material. Bauxite, also known as bauxite or high alumina, is mainly composed of aluminum oxide; it is brown or light red due to iron content, with a density of 3.9-4q / cm3 and a hardness of 1-3; it is opaque, brittle, and insoluble in water. It is mainly used for aluminum or refractory materials. Refractory brick is a shaped refractory material, which is used to build firewalls or furnaces, and the content of aluminum o...

AI Technical Summary

Problems solved by technology

[0006] Refractory mud is used as filling material, non-cementing material. After masonry refractory bricks are calcined at high temperature, because of the same chemical composition as refractory bricks, they can be effectively sintered into a whole, and have high strength after sintering and hardening; , refractory mud has almost no strength, and it cannot be effectively bonded with refractory bricks, and accidents such as collapse and overturning are prone to occur during the masonry process, posing a great safety hazard
