Coating process: coating construction process for inner wall of storage tank

Core tip: in all kinds of paint coating construction, the inner wall coating of storage tank is different from the outer wall coating In order to effectively ensure the quality, there is a complete set of procedures for the inner wall coating of storage tank Taking phenolic epoxy coating as an example, it is required that the dirt of steel plate cannot be contacted in the project site, which will cause damage to the inner wall coating of storage tank Therefore, every effort must be made to keep the working area clean It is a good way to keep the environment around the tank inlet area clean Before entering the tank, the foot cover can be put on first In every construction link, it must be followed Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: in all kinds of paint coating construction, the inner wall coating of the tank is different from the outer wall coating In order to effectively ensure the

site, which will cause damage to the inner wall coating of storage tank Therefore, every effort must be made to keep the working area clean It is a good way to keep the environment around the tank inlet area clean Before entering the tank, you can put on the foot cover first In every construction link, you must maintain the cleaning accordingly When painting and construction, you must establish a rain shed to cover the facilities and equipment Prepare generator and enough oil during construction to ensure the operation of all construction equipment, such as air compressor lighting There are minimum and maximum temperature conditions for the storage of lamps and coatings Before and during the construction, facilities must be built to ensure that the coatings are stored under the correct temperature conditions The paint surface must be at least 3 ℃ higher than the dew point temperature After sandblasting, primer spraying must be carried out immediately During the construction of tank coatings, this condition must be maintained to ensure the curing of the coatings In order to meet this requirement, such as using single pipe For the construction of high pressure airless spraying mode of the feed, the airless spraying pump with large pressure ratio and appropriate nozzle pipe length should be selected to increase the total output fluid pressure to ensure smooth feeding and good atomization, and the nozzle with appropriate caliber and flow rate should be selected to ensure that the mixed coating can be used up within the operation period In addition, due to the low temperature in winter construction, the viscosity of the paint is greatly increased According to previous experience, the method of increasing diluent is used to reduce the viscosity However, when using solventless epoxy, if only relying on this method, it will lose the significance of using solventless epoxy Therefore, in the use process, the paint shall be stored indoors or preheated properly, so that the temperature of the paint itself is not lower than 15 ℃, so as to improve the temperature of the paint to reduce the viscosity, meet the requirements of spraying, and properly increase the pressure of the paint pump, and shorten the length of the Painted Leather pipe as far as possible, so that the paint can be sprayed normally It is possible to use a dehumidifier As a guiding requirement, the relative humidity during sand blasting should be controlled within 40-60% depending on the specific construction environment and the actual type of construction coating During sand blasting, sufficient ventilation must be provided to ensure the visibility of safe work Flexible ventilation pipes should be used to remove the dust immediately after sand blasting The ventilation system must prevent the concentration of solvent vapor in the storage tank from exceeding Over 10% of the minimum explosion limit The above is the construction process of tank inner wall coating, hoping to help you Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating
