Float bead introduction of parameter of brick of light qualitative heat preservation floats bead brick of light qualitative heat preservation wants in order to float bead the handicraft of fire prevention of adiabatic heat preservation that is make it of crucial raw material. Float bead it is the siliceous aluminium that goes out with medium is being weighed in power plant coal ash qualitative sandwich glass is hollow bead body. Surface layer of hollow ﹑ of thin ﹑ of wall of its body light ﹑ is bright and clean fireproof performance of ﹑ heat-resisting ﹑ is good. Apply float bead this kind of high quality characteristic, producible produce the light qualitative adiabatic thermal insulation with a good character of adiabatic heat preservation fireproof insulation material. Production is made float bead brick of light qualitative heat preservation can choose take shape of half dry method.
Float bead brick of light qualitative heat preservation is in the level such as character of concussion tenacity, heat-resisting, coefficient of thermal conductivity, technical properties is good at current in block insulation material, and can with compare of silicate plant fiber. The furnace of kiln of various Zuo lukewarm industry that of application of general in order to spends this kind of raw material to fall in 1200 ℃ , accomplish the heat that carry Zuo effect, reduce cost can lookingly. Float bead on equipment of lukewarm machine of the industrial kiln heat that brick of light qualitative heat preservation uses in the unit such as project of building materials of metallurgical industry, mechanical equipment, chemical plant, crude oil, adornment, light industry, power and Zuo , general but environmental protection is energy-saving 15%~40% , it is a kind of good new-style light qualitative insulation material.
Float bead brick of light qualitative heat preservation uses what raw material reachs shirt-sleeve agent to choose float bead brick of light qualitative heat preservation is in make in whole process, of raw material and mixture of be in harmony choose crucial.
1, float bead in choosing, float for nothing bead organic chemistry character is planted because of coal reach an operation technological process is different have however very big rise and fall, produce in making, can classify its grade apply. Say commonly, in order to use unit weight under surface layer of 0.4g/cm3, bead body bright and clean, whole bead rate is in 98
% the left and right sides and the comparison with iron inferior water content suits. In apply at production is made, also should value float bead particle size distribution is formed, it can endanger the figuration character of handicraft, fire to machine craft and technical properties.
2, of shirt-sleeve agent choose float bead belong to blame plasticity material, acute communicable diseases of grain content cat, accumulation density is big, select shirt-sleeve agent effectively and making clear its to use an amount is production make float bead of brick of light qualitative heat preservation important one of.
Use shirt-sleeve agent to answer comply with 3 standards:
When ① normal temperature falls, shirt-sleeve agent should with float bead surface layer has admirable physics to suck Fu and organic chemistry to kiss cooperation to use, well-balanced and can dispersive change surface layer of Yu Piaozhu body and produce to all be ticked off stick the; that accept film to fill after press and doing impetuous, float bead still can first-rate is stuck receive together, in the lukewarm limits of preexistence of ② of compressive strength; with make base substrate is had certain, shirt-sleeve agent still is stuck well receive float bead, decrease or raise; stage by stage or making base substrate compressive strength unapt is shirt-sleeve agent can with float bead report of organic chemistry of surface layer generation, reactant still is provided stick receive float bead mixture of be in harmony of working ability; is smooth below tall , in comparing lukewarm when should stick as soon as possible receive float bead, or fall in tall meeting and float bead the response with surface layer proper generation, the Mo Laishi posture that changes those who decide into Er to have taller tenacity, be beneficial to make
Taste compressive strength promotion or other and characteristic improvement.
The agent includes common confluence to mix without model, handsome date compound sex 3 kinds: Have saggar, siliceous natrium, vitriolic aluminium, ammonium sulphate without mixture of model be in harmony
2 hydrogen aluminium, changes the; such as aluminium to model confluence agent has dextrin, hydroxide aldehyde of colophony of aldehyde of methylic cellulose, Niao, make water compound sex points to the; such as epoxy resin shirt-sleeve agent is general 2 plant or a few kinds of confluence.
Emphasize here, to shirt-sleeve agent of application, need precompose to solve commonly. If be mixture of be in harmony with saggar when, should choose these to have tall plasticity to be out of shape with tall dispersive sex, should begin before application broken broken settlement; with epoxy resin kind when reaching shirt-sleeve agent, want beforehand to begin diluent, the methylic like dextrin and hydroxide cellulose hydrolyze that should make beforehand reacts. Besides, produce in the technical standard according to light qualitative adiabatic brick and secret recipe also wanting in making, float bead use quantity, use mixture of different be in harmony, make clear dosage of its be convenient to use.
