Abstract
The invention relates the cleaning agent and preparing method. The cleaning agent comprises 60-80% dichloropropane, 5-20% methylchloro-form and 5-20% difluo-monochloroethane. The cleaning agent has the advantages of good cleaning effect, non remain, and good insulativity. The cleaning agent has good withstand voltage, and the pressure resistance value is 25kv. The cleaning agent solves the problemthat moisture coagulated on the surface of substance.
Description
Technical field
The present invention relates to a kind of clean-out system, especially a kind of clean-out system that uses under can online at electronic machine (charged) state the invention still further relates to the production method of this precision electronic device on-line detergent.
Background technology
The circuit card of precision electronic device and other element are in the process of utilization and operation, and regular meeting is subjected to the infringement of static and dirt:
1, the harm of deposit dirt: pollutents such as airborne various dusts, smog, organism can and be influenced by electrostatic and condense upon on the circuit card with air-flow, and absorb airborne moisture and on the electronic component of electrical equipment and circuit card, form microcircuit, the pollution of circulation thing can cause circuit to change or stop the normal signal transmission function, thereby fault appears, even cause interrupting, cause heavy losses.
2, electrostatic harm: electronics can be subjected to the harm of cumulative bad static, charged particle in Working environment, static discharge can cause the puncture of components and parts or performance to become bad, especially under high temperature and wet environment, also can produce electric leakage, even short circuit, specific inductivity and loss factor change, cause circuit to break down, cause losses such as communicating interrupt, information dropout.
The reason that electronic circuit apparatus has an accident mainly is: various dissimilar electronicss are in service continuously for a long time, all will be subjected to Effect of Environmental bar none.These equipment are under its cooling supply air system and the electromagnetic field effect of self, dust in the environment, greasy dirt, moisture, salt, static, charged particle, various corrosives and gas etc., can cause serious harm gradually to these equipment, as " the soft fault " that " microcircuit " effect causes of adding that forms by these pollutents, and make the equipment cooling degradation, equipment is caused slow corrosion and oxidation, thereby cause the fault such as contact resistance increase, loose contact of various contacts to some extent.
By can prevent the harm of organic dirt, dust, moisture effectively to the cleaning of electronics circuit, prevent galvanic corrosion, eliminate static, guarantee the normal operation of equipment.
Traditional electronic product purging method; mainly contain with bellows and brush; with hairbrush brush, use cotton ball soaked in alcohol wiping etc., it is low that these provide efficient; cleaning performance is poor; concealment part can't touch, and pollutent is difficult to thorough removing, and causes artificial fault easily; to shut down generally speaking in addition and could safeguard, influence normal equipment operation.Especially in the necessary non-stop run of equipment requirements, under the situation about can not cut off the power supply, be difficult to especially accomplish to clean completely comprehensively.
Requirement according to equipment washing, some electrical equipment electrified cleaning agents have appearred on the market, but its at high pressure resistant, high-insulativity, do not burn, aspect such as non-corrosiveness and environmental protection has weak point, along with country is faced with superseded situation to the raising of environmental requirement.
Summary of the invention
A kind ofly do not burn for the purpose that solves above-mentioned weak point this invention provides, good insulating when cleaning, environmental protection, non-corrosiveness, online (charged) clean-out system that volatile performance is good.
Purpose of the present invention also provides the production technique of above-mentioned clean-out system.
Purpose of the present invention can reach by following measure:
This precision electronic device on-line detergent, it comprises dichloro pentafluoropropane, trichloroethane and dichloro one fluoroethane, the quality percentage composition of three kinds of components is as follows:
Dichloro pentafluoropropane 60～80%;
1 5～20%;
Dichloro one fluoroethane 5～20%.
Purpose of the present invention can also reach by following measure:
Described clean-out system also comprises one or more component of trichloromethane, polyoxyethylene nonylphenol ether.
The percentage composition of described trichloromethane, polyoxyethylene nonylphenol ether is respectively: 3～6% and 0～5%.
Described clean-out system is that 75% dichloro pentafluoropropane, 10% 1,10% dichloro one fluoroethane, 4.5% trichloromethane, 0.5% polyoxyethylene nonylphenol ether are formed by massfraction.
Another object of the present invention can reach by following measure:
The production method of this precision electronic device on-line detergent may further comprise the steps:
Above-mentioned required component ratio is as requested packed in the airtight reaction vessel, and stirring reaction is 1 hour under 60～80 ℃ of normal pressures.
Precision electronic device on-line detergent of the present invention compared with prior art has following advantage:
1, the cleaning force height of this clean-out system, noresidue, insulativity reaches 10
12The order of magnitude, and insulativity reaches 2.6 * 10
12Ω, the insulativity of existing clean-out system is 10
8The order of magnitude, thus greatly reduce potential electric leakage danger in charged cleaning process.
2, this clean-out system has higher proof voltage, and its proof voltage value is 25kv.
3, this clean-out system has solved the rapid problem of water in air segregation junction at body surface of being brought owing to the clean-out system volatilization that cause that reduce of body surface temperature that be cleaned when satisfying the volatility requirement.
