Description
Technical field:
The present invention relates to spray material production technical field, specifically a kind of cement kiln external system preparation using method of high-strength sprayed material.
Background technology:
Often there is the dispersion of maintenance point in cement kiln external system refractory materials maintenance process, each point task amount is few, the problems such as the duration is nervous, traditional maintenance is all the mode of taking to pour into a mould, this mode operability affects larger by position, as kiln head cover, tertiary-air pipe position, need to build very high scaffolding maybe to need to carry out high-altitude material and phoresy, require great effort time-consuming, affect maintenance efficiency, and need in casting process to carry out formwork, maintenance, baking, technique is loaded down with trivial details, and workload is large, often the construction quality of expendable material in order to work to tight deadlines, affects whole service life.
Summary of the invention:
Technical problem to be solved by this invention is to provide the high-strength sprayed material of a kind of cement kiln external system and preparation using method thereof, and through well-designed, strengthening matrix also optimizes the chemical constitution of mould material, to guarantee the excellent properties of material.
Solve technical problem adopt following technical scheme:
The high-strength sprayed material of a kind of cement kiln external system, is characterized in that: comprise following component by weight percentage,
The aluminium content of described andaluzite is 55% ~ 60%.
A kind of cement kiln external system preparation using method of high-strength sprayed material, it is characterized in that: comprise the following steps, various solid material is weighed, after mixing by predetermined proportioning, through weighing, packaging becomes packed unshape refractory, during use, takes packaging apart, pour material into stirrer, add water and stir into mould material, pour into a mould on request, then through maintenance, Dryly use.
Aggregate fraction, with flint clay, andaluzite is main, and flint clay is agglomerated material, and the low aluminium of high silicon, has good alkaline resistance properties; Andaluzite is sillimanite race raw material, and aluminium content is 55% ~ 60%, and itself also has good alkaline resistance properties, and is converted into mullite under high temperature, and with a certain amount of volumetric expansion, is conducive to the high-temperature behavior improving refractory materials.
Base portion, adopt alumina micro mist, high-purity silicon oxide micro mist composite superfine powder, make the dispersiveness of material, Packing character is improved
Thus the over-all properties of material is significantly improved.
Additive part, adopt organo-mineral complexing softening agent, silicate cement and quick dissolved sodium silicate compound accelerator for hardening, effectively improve the adhesive rate of material, workability improves.
Silicon oxide super-fine powder and alumina micro mist facilitate mullitization and react:
3Al
2o
3+ 2SiO
2→ 3Al
2o
3.2SiO
2(mullite)
Adding of ultrafine silica powder makes mould material produce hydrogen bonded in the past at 80 DEG C, because of dehydration reaction when 80 ~ 600 DEG C:
SiO
2-Si-OH+HO-Si-SiO
2→SiO
2-Si-O-Si-SiO
2+H
2O
Form firmly Si-O-Si key, present three-dimensional reticulated structure, improve bonding strength, especially medium temperature intensity, compensate for the defect of conventional spray paint material;
In sum, this proportioning composition had both made matrix strengthen, and allowed again aggregate mate with Matrix optimization, added multiple compound additive, both improve material over-all properties and which in turn improved construction spraying effect.Thus it is low to ensure that material obtains rebound rate, alkali resistant corrodes, and hot strength is high, the many performances of good in thermal shock.Spraying application is without the need to carrying out formwork, and technique is simple, and operating efficiency is high, and coverage rate is comparatively wide, flexible operation mode, is suitable for the outer refractory materials maintenance of kiln.
In order to comprehensively pass judgment on material property, detect the test of normal temperature, high temperature physicochemical property and alkali resistant.
Various solid material is weighed by predetermined proportioning, and mixing and water adding stirs, and sample preparation, reaches following performance after testing
1, physicochemical property is as following table
2, alkali resistant: one-level.(GB10696-89)
The invention has the beneficial effects as follows: spray material prepared by the present invention, have that adhesive rate is high, intensity is high, wear resistance is good, thermal conductivity low and high temperature volume stability, and during construction, adopt spray regime need not set up template, need not toast, be applicable to new type nonaqueous cement production line kiln external system.
