Mortar used for quick leaking stoppage of nuclear power station accident cooling water pipe leakage

Abstract

The invention discloses mortar used for quick leaking stoppage of nuclear powder station accident cooling water pipe leakage. The mortar is prepared from, by weight, 10-20 parts of cement, 6-10 parts of mineral powder, 30-40 parts of river sand, 8-10 parts of dispersed emulsion powder, 6-10 parts of polyphenyl ether, 8-12 parts of nanometer lead particles, 8-12 parts of polyvinylidene fluoride, 10-15 parts of graphite particles, 10-13 parts of super absorbent resin, 8-12 parts of charcoal particles and 6-10 parts of silicate. The invention aims at providing the mortar used for quick leaking stoppage of nuclear powder station accident cooling water pipe leakage. According to the mortar used for quick leaking stoppage of nuclear powder station accident cooling water pipe leakage, the mortar is good in flexibility, strong in adhesive force, and capable of quickly swelling and solidifying after the mortar is mixed with water so that quick cramming of the nuclear power station cooling water pipe can be achieved, and the mortar has an isolation function on three rays of alpha, beta and gamma of nuclear radiation after the nuclear powder station cooling water pipe is crammed so that further spreading of a nuclear leakage accident can be prevented.

Description

technical field

[0001] The invention relates to a plugging mortar, in particular to a fast plugging mortar used for leakage of cooling water pipes in nuclear power plant accidents. Background technique

[0002] Nuclear power is a clean, efficient and relatively safe energy source. A nuclear leakage accident in a nuclear power plant refers to the leakage of radioactive substances in the nuclear reactor, causing environmental pollution and exposing the public to radiation hazards. Therefore, it is necessary to have a little knowledge of how to deal with nuclear leaks to prevent accidents. The general impact of nuclear leakage on personnel is manifested in nuclear radiation, also called radioactive substances. The energy emitted by radioactive substances in the form of waves or particles is called nuclear radiation. Nuclear explosions and nuclear accidents have nuclear radiation. It has three radiation forms: alpha, beta and gamma. Alpha radiation can be blocked with a piece...
