Description
Technical field
The present invention relates to the charged sanitising agent of sophisticated electronics.
Background technology
Sophisticated electronics is in secular continuous operational process, because of comprehensive pollution things such as the various dust and dirt of buoyant in the atmosphere, salt, greasy dirts, and form electrolytical moisture films such as being dissolved with salt because of condensation, the adsorption of the adsorption by machinery, the adsorption of intermolecular forces and electrostatic force causes the severe contamination of sophisticated electronics, the heat-sinking capability of sophisticated electronics is descended, influence its operating mass and serviceability.These pollutents also form additional " microcircuit effect " and " slow corrosion " effect to the circuit in the equipment.Cause the rising of the failure rate such as the error rate, obstacle rate, bad plate rate, failure rate of sophisticated electronics to some extent.Therefore, must regularly carry out cleaning to the long-term sophisticated electronics of operation continuously.
Sophisticated electronics is widely used in various economic departments, carries out if having a power failure during cleaning, will cause enormous economic loss, so it is necessary that cleaning agent for electrified accurate electronic apparatus is provided.
Because the singularity of sophisticated electronics has proposed very high requirement for the product performance of sanitising agent.If the sanitising agent that uses is inappropriate, if promptly lack the sanitising agent of strict technical indicator standard, not only then can not reach the purpose of cleaning equipment, can cause serious consequence on the contrary.In the charged cleaning industry because the performance of sanitising agent is not good, temperature moment that order is cleaned object in the cleaning process that ubiquity descend 20～30 ℃ phenomenon.This surface that causes being cleaned object the condensation phenomenon occurs or produces ice-crystal effect, forms moisture film or thin ice, causes the surface insulation resistance of equipment to descend rapidly, and leakage current increases, even causes short circuit, causes accident.
Chinese patent discloses a kind of clean-out system of forming with CFC-113, methylene dichloride and zellon in 1996 No. 96102785 (application number), and explanation can be at the greasy dirt on the removing equipment under the situation of not cutting off the power supply, dust, moisture, and to the components and parts on the equipment, hard goods, insulating material without any corrosive nature.
But there are following five problems in this patent of invention:
(1) it has used by the relevant pact of United Nations Environment Programme (UNEP) and has specified the CFC-113 that need eliminate;
(2) it does not indicate the upper voltage limit that is allowed when charged the cleaning;
(3) it does not provide this invention of data declaration in cleaning process, whether the condensation phenomenon can occur;
(4) it does not provide this invention of data declaration in cleaning process, whether ice-crystal effect can occur;
(5) it does not provide the safety performance in the cleaning process of this invention of data declaration.
Summary of the invention
The purpose of this invention is to provide a kind of cleaning agent for electrified accurate electronic apparatus, it has overcome the defective of above-mentioned prior art, does not produce condensation phenomenon and ice-crystal effect when cleaning, and cleaning performance is good, simultaneously, the Ozone Depleting Substances (ODS) that does not contain United Nations Environment Programme (UNEP) and forbidden.
Sophisticated electronics sanitising agent provided by the invention is characterized in that by 1,1,1,2,2,3,4,5,5,5-Decafluoropentane (being called for short HFC43-10/tDCE), MSX 4518 (being called for short HFE7100), 1,1,1,3, and the 3-pentafluoropropane (is called for short HFC245
Fa), at least a and stablizer composition at least a and alkane, alkene, alcohol, the ketone in a chlorine pentafluoropropane (be called for short HCFC AK-225) and dichloro one fluoroethane (being called for short HCFC141b) the ODS surrogate.
All containing hydrogen in the molecular structure of these ODS surrogates, can finish just basic the decomposition before arriving smelly fluorine layer, is the surrogate that belongs to environment-friendly type.Wherein, the ODP value of first three kind is zero, is to belong to nonvolatil ODS surrogate; The back is to belong to cambic ODS surrogate for two kinds.
If use above-mentioned ODS surrogate separately, the ability of then removing the comprehensive pollution thing is good inadequately, and cost will be too high.Therefore, cleaning agent component of the present invention also relates to alkane, alkene, alcohol, ketone and stablizer.
Embodiment:
Further set forth product compositing formula of the present invention below by embodiment.Wherein, related ODS surrogate is nonvolatil among the embodiment 1-4.ODS surrogate among the embodiment 5-6 is to belong to cambic, but its price is lower.
