Abstract
The invention discloses nuclear radiation shieling lead clothes and a production method thereof, relating to an anti-nuclear radiation technology. The production method comprises the following steps of: uniformly laying lead fiber yarns with diameters between 0.1 and 0.3 millimeter in a wood mold to form a lead fiber yarn sheet; taking the shaped lead fiber yarn sheet out and spraying a natural rubber adhesive; putting the lead fiber yarn sheet on which the natural rubber adhesive is sprayed into a metal mold, treating under the vulcanizing pressure condition 300 kilograms at the temperature between 160 and 200 DEG C in a high-temperature vulcanizing machine for 350-450 seconds, cooling to normal temperature and taking a vulcanized chip out; and sewing the chip in a textile fabric to obtain the lead clothes. The method has a simple and reasonable process, and is easy for production and manufacturing; the lead clothes or a lead screen has low material consumption, is convenient to wear, and has high durability; and the field irradiation time can be saved by 50 percent for maintenance personnel.
Description
Technical field
The present invention relates to the core radiation protection technology, use the material production technical field especially for what make plumbous clothing that radiation proof uses or lead shield inner bag.
Background technology
Studies show that, the external exposure line of nuclear power station is mainly gamma-rays, it is mainly from the fission product of nuclear reaction with by the pipeline of neutron activation and valve, appearance due to activation corrosion product in pipeline, cause the deposition of radioactive particulate in pipeline, make control zone a lot of upkeep operation site surrounding dosage higher, increased staff's external irradiation dose, general employing shielding is removed.Therefore, make every effort to highly effective and safe, low cost and save the space on shielding material is selected, usually selecting steel, lead, normal concrete and loaded concrete etc.The intensity of steel is better, but price is higher; Concrete more cheap than heavy metal, but density is little, and shielding thickness is large; Plumbous advantage is that density is high, fusing point is low, anti-corrosion, to gamma-rays good adsorbability is arranged and be difficult for by through characteristic, be easy to cast and relative shielding thickness less, so lead is the shielding material of first-selection.
At present, China is at the nuclear power station of operation, the shielding goods (plumbous clothing or lead shield) that control zone biological shielding system adopts are mainly: " the block stereotype of gapless solid metal " of roll forming, this metal stereotype exist that lead equivalent is low, conformal performance can be poor, the generation waste material is many, resource utilization is not high; Product is heavy, causes shielding operation labor intensity large, and staff's exposure time is long, dosage is large, easily causes heat-insulation layer distortion, tenesmus, and the control zone roentgen dose X increases, and safety coefficient is low, and potential risk is large; Be not suitable for the special-shaped equipment such as pipeline, valve and personnel's shielding; And be difficult for decontamination, the drawback such as serviceable life is short.Therefore, stereotype shielding goods are difficult to compatibility on shield effectiveness and structure function, are not suitable with nuclear industry sustainable development and the needs that people-oriented.
Studies show that, Antiradiation biological shielding goods also must possess good physical and mechanical property (obdurability, thermal stability etc.) except will having higher shield effectiveness.It is reported, current, the material and the goods that are used for the Antiradiation biological shielding mainly contain following four classes.One class is take general industry lead as main, the block stereotype of the gapless metal of roll extrusion or moulding by casting, lead brick, sheet lead concrete etc.; Equations of The Second Kind is take lead powder as main, and rubber, polyethylene foam etc. are as mixed flexible article and coating, the tackifier etc. that are composited of base-material; The 3rd class be with the block sheet lead of gapless metal as heart, ectonexine coats crosslinked foaming material and the continuous synthetic fibre material product of synthetic rubber; The 4th class is to make the light-weight high-strength materials such as cenosphere with heavy metals such as lead.Facts have proved, although stereotype, sheet lead goods Antiradiation effect are better, when building shielding harness, use amount is large, builds difficulty large, and inefficiency produces waste material many, and potential risk is large; And stereotype goods conformal performance is poor, can not bend, and is not suitable for the shielding of the special-shaped equipment such as pipeline, valve, and careless manipulation easily drops and hurts sb.'s feelings or damage equipment.And mixed goods, coating and the tackifier that is composited of lead powder and rubber, polyethylene foam-material, though have certain flexibility, but because the lead powder particle easily gathers, be difficult in base-material evenly mixed, therefore shielding properties is inhomogeneous, and lead equivalent is low, rubber and tygon etc. are easily aging, affects shield effectiveness, brings by the danger of radiation to the staff.The plumbous cenosphere light-weight high-strength material that waits heavy metal to make, though the Antiradiation performance is excellent, cost is high, cost is large, generally is used for the anti-nuclear radiation of nuclear rocket engine and leaks.
The inventor if substitute thick and heavy stereotype, sheet lead with galvanized wire, makes the sandwich layer of chip shielding goods after further research, can overcome the defective of above prior art.
Summary of the invention
The object of the invention is to propose a kind of nuclear-radiation shielding lead garment with certain extensibility and intensity.
The present invention includes weaving face fabric and lining, make chip between described weaving face fabric and lining, lead fiber silk and the vulcanization of rubber that described chip is 0. 1mm～0.3mm by diameter form.
The lead fiber silk that the present invention adopts can satisfy the needs of longitude and latitude knitting forming, owing to having good physical-mechanical properties (obdurability, thermal stability etc.), therefore can prolong the sandwich layer of swaging slabbing shielding goods by braiding, produces waste material few.Under the prerequisite that does not reduce radiation proof function, make saving, conveniently wear with material of plumbous clothing or lead shield, durability is good, and the maintainer is subjected at the scene according to time decreased 50 ﹪.
Another object of the present invention is to propose the production method of nuclear-radiation shielding lead garment.
Comprise the following steps:
1) all spread the lead fiber silk that diameter is 0. 1mm～0.3mm in wooden model, form the lead fiber silk sheet;
2) the lead fiber silk sheet after the taking-up typing, spray with natural rubber adhesive;
The lead fiber silk sheet that 3) will spray natural rubber adhesive is placed in metal die, and in 160～200 ℃ of high temperature vulcanized machines, part under 300kg sulfide stress bar acted on after 350～450 seconds, was cooled to normal temperature, takes out the chip of sulfuration;
4) chip is sewn in textile cloth, makes plumbous clothing.
Technique of the present invention is simple, reasonable, is easy to manufacture, and can greatly reduce leady raw materials.
Embodiment
1, the making of plumbous clothing core:
First make the wooden model of plumbous clothing core, all spread the lead fiber silk that diameter is 0. 1mm～0.3mm in mould, be pressed into the wooden model typing above mould, form the lead fiber silk sheet.
Take out the lead fiber silk sheet after finalizing the design, adopt the spraying of natural rubber slurries.
Lead fiber silk sheet after spraying is placed in metal die, and in 160～200 ℃ of high temperature vulcanized machines, part under 300kg sulfide stress bar acted on after 350～450 seconds, was cooled to normal temperature.
Take out the chip of sulfuration from matched moulds.
2, ready-made clothes production:
Chip is sewn in textile cloth, makes plumbous clothing.
3, Contrast on effect table:
