Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, are used for the anticorrosion of containing graphene heat exchanger more particularly, to one kind
Coating and preparation method thereof.
Background technique
It is introduced that etching problem spreads all industries, and due to corrosion and in order to prevent and mitigate the harm of corrosion, it must not
The cost that do not pay is commonly referred to as corrosion loss in China.Economic loss caused by corrosion can be divided into direct losses and indirectly damage
It loses, direct losses include: more exchange device and component expense, price for repairing and corrosion protection expense etc..Indirect loss includes: production suspension induced losses, accident
Reparation, corrosion leakage cause the loss of product, corrosion product accumulation or corrosion failure caused by efficiency reduce and corrosion product
Lead to loss caused by final product quality decline etc..According to statistics, various countries' annual economical losses as caused by corrosion failure account for about
The 1.5%~4% of current year national economy total output value, it is horizontal and different with the different economic development level in various countries and corrosion control.
It loses and is particularly acute caused by China, corrosion, according to the data of " Chinese Investigation On Corrosion report ", the year corrosion of China in recent years
Loss about 500,000,000,000, accounts for about the 5% of national economy total output value.
Heat exchanger is the commonly used equipment that hot transmitting is mutually carried out between the two media different for temperature, it be chemical industry,
Pharmacy, food, machinery and a kind of widely used commonly used equipment of other industrial departments however industrial practice production in, heat exchange
Device because fouling, corrosion cause heat exchanger performance constantly decline until damage event frequent occurrence, directly or indirectly (such as: shut-down
Maintenance etc.) cause very huge economic loss.In recent ten years, although the corrosion and corrosion protection technology of heat exchanger is in progress,
Generally speaking, the paces of heat exchanger performance research and development are not caught up with also.Currently, highly corrosion resistant material is generally used in face of corrosion,
Such as: two phase stainless steel, Hastelloy, titanium, titanium alloy and tantalum, zirconium.But these highly corrosion resistant material prices are expensive, system
Cause this very high, general enterprises are difficult to bear, and are unfavorable for promoting.Coating corrosion resistance coating can not only make heat-transfer surface have anti-impact
The performances such as brush, impermeabilisation, moisture-proof change, and there are also the effects on isolating metal surface and media contact and scale inhibition, to a certain degree
On heat exchanger performance and service life can be improved.So going out highly corrosion resistant with low cost development and scale-inhibiting properties are good and resistance to steam is blown
The coating swept has reality well to solve the problems, such as the corrosion failure of heat exchanger, reduce maintenance times and maintenance frequency
Meaning.
