Visual inspection and processing of pre laying refractory material

Boiler refractory brick masonry for planning is not the same for different, some refractory brick standard and scale error can not be satisfied with the penetration of building qualityrequirements, especially for hook range, azimuth and swollen joints of pipeline and the demand of pre laying refractory brick selection, processing or modification. According to the construction unit and product properties of refractory brick and insulating materials, all need the rainproof, moisture-proof, masonry construction is in the boiler plant engineering all completed before beginning construction, time is very tight, so the construction preparation work is very important

Some of the furnace body layout on boiler lying disorderly and the quality demand strict site, use of shaped refractory brick masonry part, a part of elected for pre laying, the pre laying intention:

1 see refractory brick shape is the quality demand is not to the satisfaction of the refractory brick masonry, according to the supply of a variety of refractory bricks and viewing and processing are not the same error mutual deployment status of application.

2 see planning drawings and refractory brick use is not a fault.

3 the operation personnel know characteristic and quality requirement of furnace body layout, understand the methods of operation, construction and what information the application state.

4 see refractory brick masonry function and quality status of mud

5 pairs of new materials, new technology and new method of operation to experiment

Pre laying flat places usually consolidation in the room. Refractory brick and method of operation of the use of the pre laying all should be the same as the formal construction conditions, in order to truthfully reflect the existence of doubt. The pre laying results should be recorded, about the existence of doubt to have solutions.

Modulation principle of slurry used for refractory brick

Brickwork with refractory slurry should follow the following principles:

(1) to deal with all kinds of refractory slurry pre experiment and pre laying brick front, confirm the bonding time, different mud initial setting time, consistency and water;

(2) Modulation of different mud to use different instruments, and timely cleaning;

(3) Modulation is not homo0geneous slurry to use clean water, water should be accurate weighing, blending uniformly, adjusted with the use. Have good hydraulicity and modulation of hard mud shall not add water use, has the initial setting of mud may not continue to use;

(4) Modulation with phosphate mud to ensure material time trapped provisions, with the use of post set, well modulated mud arbitrarily diluted with water. This kind of mud for corrosive shall not be in direct contact with the metal shell.

We take the zero defect management idea, through the production process from beginning to end. All the time since, in the pursuit of perfect quality at the same time, also constantly improve the service system, concerned about each of your needs, to provide professional sales and technical service for you.

Water glass refractory material load

Load softening temperature learned from many test results, refractoriness water glass softening temperature usually begins with the heating temperature of a heating state after cooling refractory brick dust as fine grinding admixture of quartz sand as fine grindingadmixtures, compression temperature compression temperature for a load softening temperature and amount of water glass of water glass modulus sodium fluorosilicate content and aggregate type on.

It is the amount of water glass, refractoriness under load as the starting and the amount of water glass by load softening temperature increase, the corresponding and reduces the water glass modulus increased, load softening temperature corresponding increase, forming a proportional relationship, inorganic silicon compounds bonded refractory application development table refractoriness under load start point compression% load softening temperature is an important thermal properties of water glass and refractory material, so it should not be in thermal engineering with low modulus of water glass.

Aggregate type on load softening temperature impact load softening temperature aggregatename starting point compression brick magnetite refractory clay brick sudden cold and hot water glass refractory material has good thermal shock, in the air is subjected to time cold and hot, dry strength strength of not less than. Using three kinds of aggregate effects of rapid cooling and heating of water glass refractories. The relationship between the factors and the amount of water glass modulus and hardening agent content has little effect on sudden cold and hot experiments, and the influence factors of diameter larger species feeding.

Cold and hot water alternately performance in weight loss material name times water alternating times to strength without silica brick magnetite refractory clay brick test results show that the silica brick and magnesia brick water glass refractory thermal shock performance is poor, and refractory clay brick has good performance, the former only once.
