PA80 refractory glue mainly application between bricks and bricks in the case of high temperature connection material, in a broad sense, can also be listed as high temperature refractory mortar, PA80 refractory glue and ordinary refractory mortar whether in quality and price, are very different.

The most difference between the two is the difference in the use of temperature areas, the general static industrial kiln lining construction can be ordinary refractory mortar, or phosphate refractory mortar, and the dynamic kiln lining is best to use PA80 refractory glue, because of the dynamic mechanical pressure and kiln stress, to prevent the brick drop out of the rotation process.

There are also a variety of ordinary refractory mortar, all according to the quality of the use of refractory bricks with the same material of joint refractory mortar, refractory mortar is divided into clay and high aluminum, silicon carbide, silicon, magnesium and other different series, are joint materials of masonry refractory bricks of different materials.

PA80 refractory glue is the use of specific binder and powder, powder and ordinary clay ratio has a great change, ordinary mud is generally 160-180 purpose powder and clay preparation. The PA80 refractory glue is made of powder, add ultrafine powder, and add a variety of special binders to boil, boil the glue with a bucket alone, the use of high temperature effect is remarkable.

The adhesion of refractory mortar is very important. Poor bonding will affect the bonding of firebrick joints and reduce the service life of firebrick. Ordinary refractory mortar and PA80 refractory glue must have dynamic fluidity and plasticity. There is no fluidity and adhesion, the joints between bricks and bricks during construction will not be tight, and the phenomenon of falling bricks will occur at low temperatures.

The thermal expansion or shrinkage of PA80 adhesive is better than that of ordinary refractory mortar, and it will not separate the refractory bricks or cause the clay layer to break. Integrity and rigor and unity work better. The adhesion of ordinary refractory mortar is good in the middle and low temperature area, and the strength is good at low temperature, while the PA80 adhesive will increase with the increase of temperature, and the strength of brick integration will become denser with the increase of temperature.

PA80 refractory glue and refractory mortar are selected according to the temperature and position of the static and dynamic kiln lining, and the different materials of the firebrick.
