Description

The preparation method of a kind of protective brick and mortar
The present invention relates to a kind of preparation method of building protective materials, be applicable to architectural X, gamma-rays protection and shielding.
Present X, the gamma ray shielding protective material that uses, main employing concrete casting, stereotype, plumbous barium matrix material, they have certain protection effect as X, gamma-ray protective material, but its weak point is produced and the construction technology complexity, and the raw materials cost expense is higher.
Purpose of the present invention disclose a kind of with low cost, technology is simple, the reliable shielding material of barrier propterty.
Technical solution of the present invention is:
The present invention selects for use iron-holder to be not less than 85% greater than 35% iron ore, iron-holder greater than 35% scale oxide, barite sand, barium sulfate content, granularity requirements 0.15-2.0mm, tackiness agent adopts that the raw material of 475# silicate cement or barium cement uses that following method is at first sieved, mixed, stirring, compression moulding, maintenance, inspection matter warehouse-in.
1, iron ore: require iron level＞35%;
2, scale oxide: require iron level＞55%;
3, barite sand: require barium sulfate content to be not less than 85%, granularity requirements 0.15-2.0mm.
4, tackiness agent: adopt 425# silicate cement (or barium cement).
Production technique of the present invention is simple, raw material sources extensive, mechanical property is higher than general concrete, and ultimate compression strength 720Mpa has corrosion-resistant, radiation resistance.
Accompanying drawing 1 is the process flow sheet of X, gamma-rays protective brick.
Embodiment:
Accompanying drawing 1 is seen in A, technical process.
B, the inspection of raw and process materials: iron ore and iodine oxide squama are carried out contaminant removal, and the water flushing.
C, starting material crushing screening: earlier iron ore powder is broken into the pellet of two kinds of specifications, first kind of specification is 0.15-3.0mm.Second kind of specification is 3-10mm.Specification ratio 6: 4.Afterwards scale oxide is sieved, two kinds of its specifications are identical with iron ore.
D, stirring: all size material, in stirrer, stir in proportion, progressively add after evenly, till an amount of, water: gray scale 0.15: 0.25.
Figure 921062702_IMG1
E, compression moulding: the mixture that stirs, put into the brick pressing machine mould, at pressing machine with 280-400Hg -5/ cm 2The pressure effect under, the crimping moulding.Its brick specification is as follows:
Horizontal shaped brick (figure): a=5.2, b=11.5, c=24, d=2.5, e=5.3.
Cisoid brick (two figure): a=11.5, b=2.5, c=11.5, d=11.5, e=24, f=5.3
Its dimensional units cm requires to make in the moulding, and error is "+", "-" 1.5mm.
After pressing machine compression moulding, will release in the brick slave, but the direct sending maintenance, this moment, cementation was lower, handle with care, with anti-crushing.
F, maintenance: the protective brick after compression moulding, be placed on the smooth plank or metal sheet, cover one deck straw bag or hessian cloth above.Placing about 2 hours, begin to water.In first three sky of brick moulding, every three hours wash waters once be no less than twice night daytime, waters later every day to be no less than five times, will increase when air humidity is high and water, curing time 38 days.
G, quality test warehouse-in (dispatching from the factory): when maintaining eight days,, carry out visual examination simultaneously, air free water sky, crackle etc. are arranged because brick intensity to reach 50%, is received the brick piling.Behind the brick piling, around cover one deck straw bag or hessian cloth, when continuing to water, ended by 28 days.Carry out quality sampling complete examination at last.Project has: resistance to compression, anti-folding, degree of compactness, X gamma-rays protective lead equivalent etc.Just can become qualified product by after the above-mentioned technology.
Accompanying drawing 2 is production technique synoptic diagram of X, gamma-rays protection mortar.
Accompanying drawing 2 is seen in A, production technique signal.
B, test material: the check starting material have inclusion-free, and remove.
C, sieve: scale oxide and barite sand are sieved, require granularity, the face 0.15-2.0 that plasters a wall, the thorough brick mm of 0.15-3.0(unit).
D, mixing: with stirrer with scale oxide and barite sand, uniform mixing in proportion.
Figure 921062702_IMG2
E, check pack: whether first test mixture material uniform mixing, packs every bag of 25kg of A type, every bag of 20kg of Type B afterwards.
F, on-the-spot pairing: at the construction field (site), mixture and cement are advanced to stir, add water more one by one till suitable.Mixture and cement proportion, thorough brick are 6-8: 1, and face 4-6 plasters a wall: 1.Water cement ratio 0.4-0.6.
G, implement to require: mortar plumpness during thorough brick, require to reach 95%, the face requirement of plastering a wall reaches, and smooth compacting hole is executed at every turn and is smeared about thickness 5mm; Execute smear old body of wall (with old room transform X as, when gamma shield covers), need to remove surperficial former metope, but if cement mortar face hacking adds a certain amount of tackiness agent (107 glue or other water capacity tackiness agent) simultaneously, to guarantee its bonding strength, last press polish moulding.
Brick and mortar are selected for use:
Above X, gamma-rays protective brick and protection mortar respectively have two kinds, are respectively A type and Type B, when using the A shaped brick, use A molding sand slurry; When using the Type B brick, must use the Type B mortar, to obtain corresponding radiological protection effect.Every cubic metre of brick of usage quantity is used compound 600kg-800kg.Mortar can independently use the face of plastering a wall or ground surface.Every square meter 20-25kg is equivalent to 1mm stereotype (lead content).
