Abstract
The invention discloses a barium-based fiber protection plate, relates to a protection plate for building, and particularly relates to a protection plate for shielding radioactive rays. 80-96% of barium sulfate powder of which fineness is 0.06-0.08mm is taken as a skeletal material; non-asbestos plant fiber, cement, quartz powder, efficient coagulator, fire retardant and water are orderly added to the skeletal material; the materials are agitated into slurry; the slurry is uniformly sprayed on a molding machine to prepare specification slabs with required thickness; finally, the slabs are pressed into protection plates, and the weight percentages of the materials are 55-75% of barium sulfate powder, 1-5% of the non-asbestos plant fiber, 3-7% of the cement, 5-7% of the quartz powder, 0.5-1.5% of the efficient coagulator, 0.5-1.5% of the fire retardant and the balance of the water. A substitute material of lead which is taken as a radiation protection object is provided, and the problem that the radiation protection object using lead leads to harm to a person is solved.
Description
Technical field
The present invention relates to protective shield for building, be specifically related to a kind of radioactive ray shielding and use protective shield.
Background technology
As everyone knows, human use's radiomaterial has obtained huge interests.For alleviating the harm of x radiation x to human body, scientists finds that metal " lead " is best radiation shielding material, successfully continues to use a century so far simultaneously.In recent years plumbous toxicity causes the common attention of people, because even sucked dosage seldom, also can cause very big harm.
Widely applying ray detector in the world today is human service; Protection all is the lead base material, and according to North America Non-Destructive Testing association expert determination, these workplaces are suspended in 1-1.2 rice height with the gas field of lead; The occupational staff soakage is big, and the infringement that causes can't be estimated.
Summary of the invention
The technical issues that need to address of the present invention just are to provide a kind of barium base fiber protective shield, and it is the substitute of radiation protection article with lead that the present invention provides a kind of, and having solved is the shielding of radiation causes harm to the people problem with lead.
For addressing the above problem; The present invention adopts following technical scheme: 80% to 96% blanc fixe that with the fineness is 0.06mm to 0.08mm is an aggregate, in aggregate, adds non-asbestos vegetable fibre, cement, silica flour, efficient coagulating agent and fire retardant, water successively; Above-mentioned raw materials is stirred into slurry, and on make-up machine, spraying slurry to process uniformly needs the specification of thickness slab, processes protective shield at last;
The percentage by weight of above-mentioned raw materials is: blanc fixe 55-75, non-asbestos vegetable fibre 1-5, cement 3-7, silica flour 5-7, efficient coagulating agent 0.5-1.5, fire retardant 0.5-1.5, water surplus.
Said non-asbestos vegetable fibre is a paper pulp.
In the above-mentioned material, can replace silica flour with silicon dioxide powder.
The fineness of said silica flour or silicon dioxide powder is 200 orders.
Barium base fiber protective shield of the present invention can replace stereotype to do the shielding of harm ray, has the following advantages:
1, pollution-free, environmental protection.
2, cut off ray, absorb ray, unleaded nontoxic, fire-proof and damp-proof, sound-insulating and heat-insulating, anticorrosive, not oxidation, trouble and expense that the stereotype secondary is decorated have been reduced or remitted in construction easily.
Barium base fiber protective shield of the present invention is through detecting; Its index: detect through national radiation protection testing agency, online matter is 120kr, 2.5mmA1, under total filtercondition; The barium base fiber cement board shielding attenuation performance that 16mm is thick is 1.35mmP6, and it is 0.08mmP6mm than lead equivalent.In practical application, the thick barium base fiber cement board lead equivalent of 25mm is more than 2.0.
Barium base fiber protective shield of the present invention can be used for the shielding protection of diagnosis X radial machine room metope, also can be used for cobalt 60 treatments, the radiocurable protection of iodine.Its advantage is: but dry construction, and easy construction is prone to row.Time saving and energy saving, but can saw cobalt during construction, can follow closely, can be bonding, and also inexpensive, price only is equivalent to 1/3rd of stereotype.This product is nontoxic, and sound insulation is heat insulation, waterproof, fire prevention, radiation proof, good evenness.When harm ray protects, be the desirable substitute products of stereotype.
Benefit of the present invention: based on more than, the social benefit of product of the present invention is obvious, produces the performance of enterprises of this product and can't estimate.
Embodiment
Barium base fiber protective shield is that the blanc fixe of 0.08mm (200 order) is an aggregate with the fineness, in aggregate, adds non-asbestos vegetable fibre, cement, silica flour, efficient coagulating agent and fire retardant, water successively; Above-mentioned raw materials is stirred into slurry, and on make-up machine, spraying slurry to process uniformly needs the specification of thickness slab, processes protective shield at last;
The percentage by weight of above-mentioned raw materials is: blanc fixe 65 to 75, non-asbestos vegetable fibre 4, cement 5, silica flour 6, efficient coagulating agent 1, fire retardant 1, water surplus.
Said non-asbestos vegetable fibre is a paper pulp.
In the above-mentioned material, can replace silica flour with silicon dioxide powder.
The fineness of said silica flour or silicon dioxide powder is 200 orders.
The slab of processing needs steaming and molding, if do not have the condition steaming and molding, also can under physical environment, finalize the design naturally, but product strength density is all influenced.
What should explain at last is: obviously, the foregoing description only be for clearly the present invention is described and is done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
