Description

Efficient feed supplement of a kind of quick-drying and preparation method thereof

Technical field

The present invention relates to a kind of technical field of refractory materials, particularly relate to efficient feed supplement of a kind of quick-drying and preparation method thereof.

Background technology

At present, in petroleum chemical industry, two devices, flue, the lining of process furnace all will overhaul every year, two device lining maintenance need to spend considerable time, in maintenance, about furnace drying time only after lining construction just needs a week, so, shorten furnace drying time and become the main research object of lining material manufacturer, for the needs meeting High-efficient Production and increase economic efficiency, lining manufacturer wishes to produce the product that can shorten repairing and repair time, China is a lot of for the technology of refractory materials, but the feed supplement shortening two device lining furnace drying time is not yet occurred, petrochemical complex can not be met, the development of the industries such as refractory materials.

Summary of the invention

The object of the present invention is to provide one not only with former lining excellent bonding performance, heat-up rate is fast, and medium temperature intensity is high, high volume is stablized, and resistance to fouling is strong, and improves petrochemical industry two device lining overhaul efficiency, easy construction, saves construction cost, meets the efficient feed supplement of quick-drying of High-efficient Production needs.

Technical scheme of the present invention is: efficient feed supplement of a kind of quick-drying and preparation method thereof, comprise following component, each composition by weight: aggregate 30% ~ 60%, powder 15% ~ 35%, phosphoric acid salt 5% ~ 25%, bonding agent 1% ~ 10%, additive 0.5% ~ 3%, aggregate is the mixture of one or more in pearlstone, flint clay, alumine, light cinder brick sand, heavy brick sand; Powder is clay, closed perlite, aluminum oxide powder, alumina fine powder, silicon ash, the mixture of at least three kinds in perlite powder; Bonding agent is one or more mixtures in the mixture of high-alumina cement, pure calcium aluminate cement, water glass, phosphoric acid and aluminum phosphate and resol; Additive is the mixture of a kind of in high efficiency water reducing agent, inorganic phosphate, organic fibre or three kinds.

Efficient feed supplement of above-mentioned a kind of quick-drying and preparation method thereof, its preparation and constructional method are:

(1) aggregate and powder are undertaken being mixed to form fast drying repair material matrix by proportioning, then add bonding agent by proportioning, additive mixes;

(2) after stirring, formwork cast or manual to smear or ramming or spray to position to be repaired;

(3) after construction terminates, natural curing 24 hours;

(4) can carry out baker after maintenance, during baker, heat-up rate successively decreases by liner thickness.

The present invention after construction, natural curing 24 hours, then baker, liner thickness is no more than heating up with the speed of 50 DEG C ~ 700 DEG C per hour of 150mm, after rising to 540 DEG C, (can constant temperature 6 hours), then rise to use temperature, the free air circulation on furnace lining should be ensured between temperature raising period, eliminate the furnace drying time in an about week in the past, substantially reduce the repair time, maintenance is constructed more quick, effectively.

The present invention compared with prior art tool has the following advantages:

1, with former lining excellent bonding performance, heat-up rate is fast, and medium temperature intensity is high, and high volume is stablized, and resistance to fouling is strong;

2, improve petrochemical industry two device, flue, heating furnace computer overhaul efficiency, easy construction, save construction cost, meet High-efficient Production needs.
