Paris director: mbape may go or stay. Real Madrid may be too confident
After Paris won the French league championship this season, Leonardo, sports director of Paris Club, was asked again about mbape’s future. Speaking of Real Madrid’s pursuit of mbape, Leonardo sarcastically said: “in Madrid, they have been very confident for three years that mbape will eventually join Real Madrid. Maybe they are too confident (laugh)?” “Mbape? Discussions have always existed. We had talks in Doha. Nasser is not in Paris now. You know how important it is for him. But tonight, h...

Summary: The chemical rationale for corruption is to protect materials from corrosive substances in harmful acid-based substances and neutral substances.
The rationale for the prevention of perishable paints in general lies in the chemical, physical and electrochemical direction, as explained in detail below:
Chemical defences:
The chemical rationale for the prevention of corruption is the protection of materials from corrosive substances in harmful acid-based substances and neutral substances. Frequently, some gender compounds are added in stain-coated paints, such as aluminium oxide, hydroxide and zinc oxide, which are readily and chemically toxic to acid alkaline, with the effect of preventing corruption.
Principles for the prevention of corrupt paints and matters of concern for construction
PREVENTION:
The physical defence of corruption is that the protection materials are isolated from the corrosive substances of the outside world. The physical rationale for staining paints is the use of plastics to obtain deceptive coatings to isolate harm from protected materials, such as lead-containing paints and oil reactions, which can lead soaps to ensure that the coatings are not contamined.
Principles for the prevention of corrupt paints and matters of concern for construction
PREVENTION OF PECIFICATIONS:
Converted electrochemical effects are the addition of special substances in stain-resistant paints, so that ionizing in water and oxygen can occur in response to stain-coated paints, thereby obscuring the melting of metals, such as steel, and thus preventing the ion of metal plasma and reaching the purpose of corruption, the most common among which is arsenic.
Surface treatment
Prior to the introduction of porous paints, stipulations such as coating, oxidation, stain, water, oil, dust, etc. shall be removed from the surface of the coatings, except for stainium at ssa2.5 level.
When the painted surfaces are handled, the drying is confirmed to be irrecontaminated and sludgeed to meet the requirements of the paint, the stainless paints should be promptly painted in order to avoid two returns.
Construction environment conditions
Temperature: general control ~35°C;
Wetness: general control is not greater than 80 per cent (atmosphere); 3. Indoor construction is prohibited under rain, aerosols, greater air humidity and wind sand conditions; 4. Field operations and open-air construction are encountered, and aerosols should be packed in front of the next class, with a painted steel.
Redeployment of paints
The base painting is distributed as a proportion of A:B = 6:1;
After full punching, 23 ±2°C was skilfully constructed for 20 to 30 minutes, and the redeployment of well-trained paints was generally controlled within three to four hours and was not used in a timely manner and the redundancy was not diluted;
A minimum of six hours and a maximum of two weeks at the time of the second lactation;
The underlying paint may not be painted for the purpose of accompanying the works (12 to 24 hours);
Paints are divided by a proportion of A:B = 5:1, with a slight static replacement;
The distribution and measurement of paints, whether painted or painted, must be accurate;
In the face of an increase in the number of paints, the spacing is for the shortest period of two hours and for a maximum period of 48 hours;
Upon completion of the construction work, 48 hours will be required for use.
Paints and lanes
Errecting, rolling or spraying, such as paints in the course of construction, may appropriately add 0 to 6 per cent of the specialized dilution agent, which is not expedient and is generally coated in two or two floors.
Coating in paint is strictly calculated according to the weight given in the product, and is constructed and maintained.
2 The paints shall be kept in drying, ventilation, vagina and shall be prohibited from rain-fed trenching and close to the sources of fire; transport shall be subject to the safety requirements of flammable transport.
Principles for the prevention of corrupt paints and matters of concern for construction
3 In order to ensure the quality of coatings, open-air construction should cease in the event of wind sand, rain, snow and aerosol weather.
4 When the temperature of the environment is less than -10°C above 40°C or relatively wet is above 80 per cent, construction is not appropriate.
5 The coating shall be coated with a coating and then painted together if the painted film is fully entrenched.
The post-coated equipment shall be used after the full stipulation of the escrow (5 to 7 days in general summer, 7 to 10 days in winter and 10 to 15 days in non-soluble-agent coating systems) and the uncontaminated coating shall prevent rainwater leaching.
The winter construction work will require a complete drying of each coating, which will take longer than the summer construction requirements.
Winter construction should be carried out as far as possible in such a way as to avoid nighting or evening, with low temperature construction leading to ills such as flour, fracture, flogging, embarrassment.
