Description
Technical field
The present invention relates to sealing agent preparation technical field, specially a kind of refrigerating system plugging agent and preparation method thereof.
Background technique
The surfaceman of refrigeration and air-conditioning system, which is often, faces leakage of refrigerant problem without it will be appreciated that they occurred
Reason.Illustrate first, in any refrigeration or air-conditioning system, by the compressor compresses refrigerant gas of specific lubricating oil, the refrigeration
Gas is overheated by this effect.Then, the refrigerant of overheat enters inside condenser, and condenser is cooling by its part, directly
Liquid refrigerant is converted into it.Subsequent dewatering filter filters moisture content, continues through the expansion valve inside evaporator, evaporates
Device converts thereof into gaseous state again.
During these, different chemical reactions, refrigerant gas and lubricating oil has occurred due to decomposing, releases halogen
Plain and organic moisture content and acid.After system works a few hours, dehydrator filter starts to be saturated, and temperature starts to recycle in system, with
The fluorine contained in refrigerant gas combines, and generates acidity, irreversibly damages many components of system, leads to refrigerant stream
Speed is slack-off.As the component of refrigeration system is constantly corroded, the following refrigerant is inevitably revealed, and gas is let out
Dew causes the operating pressure of system to reduce, so that the decline of refrigerating capacity and the destruction of environment are caused, because refrigerant is also known as fluorine
Leon, itself suffers from inescapable responsibility to atmosphere cavity and Global Greenhouse Effect.
Sealing agent be it is a kind of can interact with the refrigerant of complete series, including CFC (chlorofluorocarbons include R11, R12,
R113, R114, R115, R500, R502 etc., due to the destruction and maximum to ozone layer, by Montreal protocol
It is classified as a kind of controlled substance).HFC (mainly include R134A, R125, R32, R407C, R410A (alternative refrigerant of R22),
R152 etc., depletion of the ozone layer coefficient is 0, but climate warming latent energy value is very high.It is not specified by Montreal protocol
Service life, qualitative in the United Nations Framework Convention on Climate Change Kyoto Protocol is greenhouse gases).HCFC (mainly includes
R22, R123, R141b, R142b etc., depletion of the ozone layer coefficient are only a few percent of R11, therefore, HCFC substance at present
It is considered as the most important transitional substitute of CFC substance).
Current automotive-type air conditioner refrigerating R134A system sealing agent has certain plugging effect, but its leak stopping is imitated
Fruit is poor, is easy to appear crack and water leakage phenomenon, therefore, it is necessary to improve.
