Here Concrete anti-corrosion coating Is heavy Anticorrosive coating Refers to the concrete corrosion prevention in areas with severe acid and alkali corrosion coating Such as chimney concrete, concrete in seawater, sewage pool concrete, acid-base pool concrete, hazardous waste pool concrete, medicament processing concrete, etc. Concrete anti-corrosion company with relatively early research in China --Beijing Zhisheng Weihua Chemical Co., Ltd door To study the heavy corrosion mechanism and anti-corrosion of concrete, there are dozens of different models and different functions for different working conditions Concrete corrosion protective coating.
The relevant personnel of Zhisheng Weihua Company's anti-corrosion coating applied external anti-corrosion method to the concrete surface, proposed an effective anti-corrosion coating supporting system, and made the following requirements for the performance of external anti-corrosion coating of concrete structures:
1. Anticorrosive coating shall have good permeability: ZS-1011 for concrete surface The transition coating must have very strong permeability, close the concrete pores, adhere to the surface dust of the concrete, and enhance the strength of the concrete surface layer. ZS-1011 The transition coating is compact after film forming, and also has good permeability resistance.
2. Strong adhesion of anti-corrosion coating: ZS-1034 is acid and alkali resistant if the concrete structure is in a humid environment or an alternate dry and wet environment The anti-corrosion coating must have good permeability and wettability to firmly attach to the concrete surface, so as to ensure that the coating and the concrete surface must have excellent adhesion.
3. High alkali resistance of anti-corrosion coating: the PH value of concrete is 8-12.5, and ZS series Zhisheng anti-corrosion coating must have good alkali resistance.
The following is what Zhisheng Weihua commonly uses on concrete. Different anti-corrosion coatings can be used for different anti-corrosion conditions ZS series anti-corrosion coatings can also be two or more ZS series anti-corrosion coatings as a composite coating for concrete anti-corrosion protection to protect concrete from corrosion under different acids and alkalis for a long time.
1. Prevent seawater and high-temperature steam corrosion concrete Coating: concrete ZS-711 inorganic anti-corrosion coating has good anti-corrosion and anti-corrosion functions, strong adhesion and high temperature resistance. ZS-711 inorganic anti-corrosion coating has a corrosion resistance life of more than 10 years in salt spray acid gas, underground burial, marine seawater, chemical acid and alkali, petroleum liquid, sewage and wastewater.
2. Increase heat transfer and acid corrosion resistance concrete Coating: concrete The heat exchange rate of ZS-722 acid resistant heat conduction anti-corrosion coating can be increased by more than 10% than that of the substrate without ZS-722 acid resistant heat conduction anti-corrosion coating, and by more than 50% for some materials. Zhisheng Weihua ZS-722 acid resistant, heat conductive and anti-corrosion coating inorganic modified chelating film forming solution and acid resistant inorganic oxide, in addition to high concentration of acid, alkali and hydrofluoric acid, can withstand long-term other All kinds of acid and alkali corrosion, long anti-corrosion life.
3. High temperature resistance, fire resistance, oxidation and corrosion resistance concrete Coating: concrete ZS-811 high temperature resistant anticorrosive coating can withstand 2300 ℃ for a long time. The coating has low dense oxygen permeability, which can prevent materials from oxidation at high temperature, acid and alkali gas corrosion, sulfur and carbon monoxide oxidative corrosion.
four Acid, alkali, oil and salt resistance at normal temperature concrete Coating: ZS-1034 acid and alkali resistant anti-corrosion coating, acid and alkali resistant, solvent gas and solution corrosion prevention. ZS-1034 acid and alkali resistant anticorrosive coating is used for special anticorrosive coating under the environment of acid, inorganic acid, salt and alkali in agricultural production system, and solvent corrosion in agricultural production system, which can effectively prevent electrochemical and chemical corrosion and provide long-term protection concrete Base material.
five Wear and corrosion resistance, impact corrosion resistance concrete Coating: ZS-1031 wear-resistant anti-corrosion coating has good acid and alkali resistance, high hardness, impact and erosion resistance, and strong adhesion.
six , resistant to strong acid and solvent corrosion Concrete coating ： ZS-1032 strong oxidation resistant coating can withstand the oxidation corrosion of strong oxidizing materials such as concentrated acid solutions (salt, sulfur, nitrate), strong intermediates, and comparative solvents for a long time, as well as the penetration corrosion of aviation kerosene and other oils.
seven , resistant to fluoric acid and bromic acid corrosion concrete Paint: ZS-1033 hydrofluoric acid resistant anti-corrosion coating has certain repellency to the corrosion of fluorine and bromine ions, and maintains the stability of the coating.
eight 、 Stack dedusting acid and alkali corrosion at the same time concrete Paint: ZS-1041 anti-corrosion coating for flue gas chimney has excellent chemical corrosion resistance, especially condensation sulfuric acid corrosion, acid resistance and good stability of corrosion coating. ZS-1041 flue gas chimney anti-corrosion coating has very high resistance to water vapor penetration,
