Description
Technical field
The present invention relates to a kind of disinfectant program being applicable to space control of microorganisms, be specifically related to one and effectively prevent the microbial contamination of airtight space cabin, reduce the impact of harmful microorganism on spacecraft and spacefarer, improve the sterilization process of airtight space accommodation system operation stability, belong to space control of microorganisms technical field.
Background technology
In space station, celestial body base, space ship, the environmental condition such as humiture is suitable for, and if do not taked effective control of microorganisms measure, may occur microorganism amount reproduction phenomenon, thus jeopardizes spacecraft safety and occupant is healthy.Serious microbiological pollution has been run in Soviet Union's space activity repeatedly, international space station is also being faced with severe microbial contamination situation, microorganism directly affects the quality and safety of space station air, water, food, affect the normal operation of equipment, and then threaten the life security of spaceman with healthy.According to China's manned space program, China will set up long-term manned space station, and the practice of Russia and the U.S. has proved, and control of microorganisms must be carried out in long term space station.Sterilization method main at present has the sterilization technologies such as low temperature formaldehyde vapor fumigation technology, hydrogen peroxide steam fumigation technology, low temperature plasma sterilization technology, ultraviolet radiation for sterilizing and disinfecting.
Based on above main points, the invention provides and be a kind ofly applicable to airtight space cabin control of microorganisms technical field and there is the control of microorganisms sterilization process of good control effects.
Summary of the invention
The object of this invention is to provide a kind of sterilization process being applicable to airtight space cabin control of microorganisms, one is provided effectively to prevent the microbial contamination of airtight space cabin, reduce the impact of harmful microorganism on spacecraft and spacefarer, improve the sterilization process of airtight space accommodation system operation stability.
In order to solve the problem, the present invention by the following technical solutions.
Be applicable to a sterilization process for airtight space cabin control of microorganisms, its process comprises:
Stage one, ground sterilization before the transmitting of airtight space cabin, adopt 1-4% hydrogen peroxide steam to carrying out fumigation in 2-4 hour in airtight space cabin, hydrogen peroxide steam is easily caused to the equipment of corrosion, adopt 0.1%N-zephiran wet tissue to equipment disinfection, and then entirety 1-4% hydrogen peroxide steam sterilization in cabin is installed again; Stage two, airtight space cabin is phase sterilization in-orbit, operator carried out once conventional clean cleaning every 5-10 days, sterilization in 1-6 hour is irradiated with Portable ultraviolet sterilizing lamp, for key equipment surface, cabin inwall 0.1%N-zephiran wet tissue local cleaning disinfection after cleaning.
Described hydrogen peroxide steam concentration range is 1-4%, and optium concentration is 3%; The time of carrying out vapor sterilization is 2-4 hour, and Best Times is 3 hours; Ground overall disinfection terminates the force ventilated mode of rear employing and accelerates in air and the peroxide decomposition on surface, to make in air VHP concentration to≤0.1ppm for best; The wave-length coverage of described Portable ultraviolet sterilizing lamp is 250-270nm, and best germicidal wavelength is 253.7nm, and irradiation time is 1-6 hour, within 4 hours, is best; Described N-zephiran wet tissue optium concentration is 0.1%, and wiping mode is unidirectional, not reproducible wiping back and forth, wipes and once needs afterwards to change, then wipes next local, best results; Airtight space cabin in-orbit phase disinfection cycle is 5-10 days, and 7 days best.
Beneficial effect of the present invention is:
The present invention by airtight space cabin ground sterilization technique before transmission and airtight space cabin in-orbit phase sterilization process reach the control to space microbial contamination, can effectively prevent the microbial contamination of airtight space cabin, reduce the impact of harmful microorganism on spacecraft and spacefarer, improve airtight space accommodation system operation stability.
Accompanying drawing illustrates:
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the sterilization process flow chart being applicable to airtight space cabin control of microorganisms of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaches object and effect is readily clear of explaination, below in conjunction with diagram and specific embodiment, sets forth the present invention further.
Referring to Fig. 1, be applicable to the sterilization process of airtight space cabin control of microorganisms, comprise two stages: the ground sterilization stage before the transmitting of airtight space cabin and airtight space cabin phase sterilisation stage in-orbit, the detailed process in per stage is as follows:
1, the ground sterilization stage before the transmitting of airtight space cabin, first operator prepare the hydrogenperoxide steam generator of 3%, fumigation is carried out in airtight space cabin with fumigation machine, disinfecting time is 2 hours, with 0.1%N-zephiran wet tissue, hydrogen peroxide steam is easily caused to the equipment cleaning disinfection of corrosion again, wiping mode is unidirectional, not reproducible wiping back and forth, wipe and once need afterwards to change, wipe next local again, finally install overall for cabin again with 3% hydrogen peroxide steam sterilization, ground overall disinfection terminates the force ventilated mode of rear employing and accelerates in air and the peroxide decomposition on surface, to make in air VHP concentration to≤0.1ppm.
2, airtight space cabin phase sterilisation stage in-orbit, every 7 days, first operator carry out once conventional clean cleaning, then 4 hours illumination-based disinfections are carried out with the Portable ultraviolet sterilizing lamp that wavelength is 253.7nm, finally use 0.1%N-zephiran wet tissue for key equipment surface, cabin inwall cleaning disinfection, wiping mode is unidirectional, not reproducible wiping back and forth, wipe and once need afterwards to change, then wipe next local.
