Description
Technical field
The present invention relates to nuclear radiation protection technical field, relate in particular to the production technical field of composite fibre silk for a kind of nuclear radiation protection.
Background technology
Nuclear science technology has been widely used in a plurality of fields such as national defence, the energy, industry, medical treatment, brought huge economic and social benefit, also increased the chance that people contact various radiation and are subject to its threat, nuclear and radiation safety problem is outstanding day by day and receive much concern.Radiation protection material is the key that guarantees radiation place staff and public security with equipment, is also the effective means of dissolving nuclear accident crisis, is the important leverage of military and civilian radiological safety protection, has active demand.
China is accumulating certain technology and experience aspect traditional radiation protection material, but far can not meet the new demand that current nuclear technology and nuclear industry develop safely and fast.Because lead has good nuclear radiation protection effect and lower cost, in nuclear radiation protection field, be widely applied.Stereotype, lead brick etc. generally provide stationary radiation protection as protection body of wall or nuclear facilities main body, do not possess mobility.Lead shield, stereotype, lead glass etc. also can be applied to the place that moving protection body maybe needs to provide temporary transient protection, but radiation leakage has a big risk, builds, difficulty is high, utilization rate is low, suitable type is poor.Take lead powder rubber as main flexible protective screen, protective clothing etc., possess mobile and detachability strong, the advantage of good leak tightness, but protection efficiency low (linear attenuation coefficient is little), poor stability (matrix easily aging, lead powder easily comes off), recycling rate of waterused are low (repeatedly after folding use, folding line place is damaged), use cost high (for guaranteeing the validity of protection, need frequently change).Take and there are the radiation protection articles for use that the metal fiber wire of radiation protection function is main body and will overcome above-mentioned deficiency, but rarely seen Related product.Publication number is CN101885059 Chinese invention patent, discloses a kind of preparation method of plumbous short fibre, can realize the serialization of plumbous short fibre and produce.Publication number is the Chinese invention patent of CN 102222530, the production method of utilizing lead fiber silk to prepare nuclear-radiation shielding lead garment is disclosed, compare and have advantages of that radiation protection efficiency is higher with the plumbous clothing of the plumbous rubber of tradition, because staple fibre can only adopt to prolong, press and rubber curing forming, cause its stability and comfortableness to have much room for improvement.Publication number is the Chinese invention patent of CN 103008384, discloses a kind of metal filament processing technique, has realized the serialization of metal fiber filament and has produced.If further realize the filametntary automatic weaving forming of lead-containing alloy, will greatly expand its Application Areas and result of use.The filametntary TENSILE STRENGTH of lead fiber silk and lead-containing alloy is very low, directly carries out automation braiding more difficult, and the product strength being made into is not high yet, if do not taked fixation normally to use.W elements and tantalum element have good radiation protection performance, but how as functional particles, to be entrained in matrix material and to use, and the radiation protection articles for use that tungsten alloy and tantalum alloy filament be main body of take rarely have report.How to promote above-mentioned metal fiber wire weave characteristic and combination property is to need the problem of solution badly.
