Description
Technical field
The present invention relates to drying equipment and drying process, especially for the drying equipment and the drying process of dry water self-drying type coating.
Background technology
The conventional method dry to water self-drying type coating is under nature, to realize; Disadvantage dry under nature is: dried coating film receives extraneous natural environment influence bigger; Particularly under the high humidity low temperature condition, occurring paint film does not easily do; Turn white, disadvantage such as delamination, finally make physical properties such as the hardness of filming, scratch resistance not reach requirement.So be in humidity＞80% when external environment, water self-drying type coating can not be constructed under the situation of temperature＜5 ℃, thereby has delayed the duration of factory, incurs loss through delay delivery date.And in south in 1 year most of the time humidity all bigger, that is to say that the most of the time all can not use aqueous self-drying coating, finally make the promotion and application of water self-drying type coating receive very big obstruction.In order to overcome above-mentioned part defective, the bake drying technology that present water self-drying type coating is adopted is just carried out the hot blast heat drying with just sending into after the spraying of water self-drying type coating simply in the general baking oven.Its drying plant can only be controlled heating-up temperature, and the hot blast blast that the blower fan in the baking oven is sent here is inhomogeneous, is prone to make the surface moisture of filming to volatilize rapidly; Fast degree is slow more a lot of than film coated surface because temperature raises and be coated with film inner layer; Under the situation that film coated surface has parched, be difficult to volatilize away the inside of filming can not thoroughly be parched thereby be coated with film inner layer moisture and lack partial solvent, finally cause the film coated surface uneven lustre; Paint film turns white, disadvantages such as physical property difference such as adhesive force, hardness, scratch resistance.
Summary of the invention
First purpose of the present invention provides a kind of drying equipment that is applicable to water self-drying type coating; The drying varniss time is not influenced by extraneous factor; Accelerated the speed of water self-drying type paint spraying; Shortened the construction period, production efficiency has basic assurance, make producer can guarantee both quality and quantity the ground delivery just-in-time.
Second purpose of the present invention provides a kind of drying equipment that is applicable to water self-drying type coating; Technical problem to be solved is that water self-drying type coating is being carried out in the dry run; Because blast is inhomogeneous; Cause the film coated surface uneven lustre, paint film turns white, the phenomenon of adhesive force, hardness, scratch resistance physical property difference.
The 3rd purpose of the present invention provides a kind of drying process; Film coated surface gloss through this drying process forms is even; Non-whitening; And physical properties such as hardness, scratch resistance can reach the optimum state that water self-drying type coating itself can reach, can on workpiece, form smooth evenly and the filming of excellent performance, decorate and the effect of protection thereby workpiece played.
For reaching above-mentioned first purpose and second purpose, be applicable to that the drying equipment of water self-drying type coating comprises frame, frame is provided with baking oven, has drying tunnel in the baking oven; Be provided with conveyer belt across drying tunnel; Be provided with electric heater, air velocity transducer, temperature sensor and humidity sensor in the drying tunnel, on baking oven, be provided with the air inlet and the gas outlet that are communicated with drying tunnel, be provided with circulating fan between air inlet and the gas outlet, be provided with humidifier in the circulating fan and dry exhaust outlet.
As improvement, variable frequency reducer motor is installed on the frame, variable frequency reducer motor drives the conveyer belt motion.
As specializing, described conveyer belt is the Teflon conveyer belt.
The beneficial effect of drying equipment of the present invention is: owing to be provided with air velocity transducer and circulating fan; Therefore; Can detection at any time in the drying tunnel wind speed and through circulating fan controlled wind speed and blast, make to keep a constant wind speed and a blast in the drying tunnel, owing to be provided with electric heater and temperature sensor; Therefore, can the temperature in the drying tunnel be controlled under the constant temperature; Owing to be provided with humidity sensor, humidifier and the exhaust outlet that dries, like this, can drying tunnel be remained in the specific humidity range.Based on above-mentioned structure, when water self-drying type coating entering drying tunnel carries out drying, be difficult for making the surface moisture of filming to volatilize rapidly; Make film coated surface and be coated with film inner layer and dried uniformly; Make to be coated with film inner layer moisture and partial solvent is easy to volatilize away, therefore, film coated surface gloss is even; Paint film is difficult for turning white, good physical performance such as adhesive force, hardness, scratch resistance.Owing to be provided with variable frequency reducer motor, therefore, can regulate the movement velocity of conveyer belt, thereby reach the control purpose of drying time.Owing to be the Teflon conveyer belt, its resistance to bond is good, can prevent that water self-drying type coating from bonding on the conveyer belt.
For reaching above-mentioned the 3rd purpose, utilize drying equipment to be to the step that water self-drying type coating carries out dry technology:
The workpiece that (1) will spray water self-drying type coating was sent at 5 ~ 30 minutes and is waited to do the district and wait to do 10 ~ 60 minutes, and waiting to do district's environmental condition is 20 ℃ ~ 80 ℃ of temperature, humidity 20% ~ 70%, wind speed 2 ~ 4m/s.
(2) utilize drying plant that the workpiece that scribbles water paint is carried out drying, wherein drying equipment comprises frame, and frame is provided with baking oven, has drying tunnel in the baking oven; Be provided with conveyer belt across drying tunnel; Be provided with electric heater, air velocity transducer, temperature sensor and humidity sensor in the drying tunnel, on baking oven, be provided with the air inlet and the gas outlet that are communicated with drying tunnel, be provided with circulating fan between air inlet and the gas outlet, be provided with humidifier in the circulating fan and dry exhaust outlet; Variable frequency reducer motor is installed on the frame, and variable frequency reducer motor drives the conveyer belt motion.
(3) through temperature sensor and electric heater with the adjustment to 20 of drying tunnel ℃ ~ 80 ℃.
(4) through humidity sensor, humidifier and humidity regulation to 40% ~ 60% of exhaust outlet that dries with drying tunnel.
(5) through air velocity transducer and circulating fan the wind speed of blower fan is adjusted to 2 ~ 4m/s.
(6) regulate the frequency conversion reductor, the workpiece that slowly will scribble water paint evenly is transported to drying tunnel, and drying is 30 ~ 120 minutes in drying tunnel.
The beneficial effect of drying process of the present invention is: the drying varniss time is not influenced by extraneous factor, has accelerated the speed of water self-drying type paint spraying, has shortened the construction period, and production efficiency has basic assurance, make producer can guarantee both quality and quantity the ground delivery just-in-time.Film coated surface gloss is even; Non-whitening; And physical properties such as hardness, scratch resistance can reach the optimum state that water self-drying type coating itself can reach, can on workpiece, form smooth evenly and the filming of excellent performance, decorate and the effect of protection thereby workpiece played.
