Refractory Mortars

We, Imperial World Trade Frequently Placed In Ordinary Portland Cement Mortar, Sometimes With A Little Extra Cement Or Some Fireclay Added To Make The Mixture Fireclay Mortar. A Refractory Composition Comprising Of Heat Resistant Binding System And Low Grain Size Refractory Furnaces. Mostly Used For Joining Bricks. Two Types Of Settings: Air And Heat Setting Mortar The Mortar Hardens At A Heat Above Room Temperature. The Problem With Using Regular Mortar Is That Portland Cement Can't Take The Heat. Curiously, Cement Retains Its Energy Up To Reasonably High Temperatures But Declines As It Cools Down Through About 600�° F. Ultimately All That Is Left Of The Mortar Is The Sand And Fireclay, With No Cement Binder. The Mortar Has No Strength And Easily Falls Out Of The Joints, Especially If They Are Wide. Refractory Mortar, On The Opposite Side, Is Performed With High-Temperature Cement And Carefully Selected Aggregates That Don't Expand And Tear The Mortar Apart When Heated. The International Residential Code (IRC) And International Building Code (IBC), Which Were Recently Adopted In Approximately All States And Require That Fireboxes, Smoke Chambers, And Flue Liners Be Laid With Refractory Mortar.

Mortar is distinguished between heat-setting property and air-setting property. Heat-setting property displays strength by heating after installation and air-setting property displays excellent strength at the normal temperature. Therefore, it has better select air-setting mortar in case of need special strength at the normal temperature and we are supplying mortar of various type that is suited to installation condition and fire-brick.

Refractory mortar consists of refractory powder, binder and admixture. Almost all of the refractory materials can be made for the preparation of refractory mud used in the powder. The refractory clinker powder and the amount of plastic clay as binder and plasticizer made of ordinary refractory mortar, the room temperature strength is low, high temperature molding ceramic combination has a higher strength. With hydraulic, gas or hard thermal setting bonding material as a binding agent, said binding of refractory clay, which produce less than the formation of a certain chemical reaction prior to bonding temperature hardening. The particle size of the refractory mortar varies according to the requirements, and its limit size is generally less than 1mm, some less than 0.5mm or more. Selection of refractory mortar material, should be considered with the masonry refractory products consistent with the material. In addition to the fire-resistant mud in addition to the material, you can also use the coating method or spray method for the protective coating of the lining.

Refractory mortar is a specially engineered mixture of sand, calcium aluminate,cement,and fire clay.It is used to lay fire brick in places that are exposed to extremely high temperature. Refractory mortar produced from fine grained refractory aggregate, refractory powder, binder and other additives and used for building and bonding the refractory bricks, and also repairing of furnace lining, which is mainly used in glass furnaces, hot blast furnaces, coke ovens, soaking furnaces, heat exchange, boilers and other industrial kilns. Characteristics of Mortar: High temperature strength High thermal stability Good resistance to slag erosion Good anti-stripping performance Long service life.
