Abstract
A paint constant-temperature control system device of a roll coater is characterized by comprising a paint circulating pump, a water/paint heat exchanger and a detector, wherein the water/paint heat exchanger is used for heating or cooling paint to a set temperature through water; and the detector can accurately measure the temperature of the paint passing through an outlet of the paint circulating pump and an outlet of the water/paint heat exchanger. According to the paint constant-temperature control system device, the temperature of the paint passing through the heat exchanger can be stably controlled within +/-1 DEG C. Compared with an original system, the paint constant-temperature control system device has the advantages that yearly consumption of organic solvents on a colorful coating production line can be reduced by 65%, and indexes of the product quality and the qualified rate are both stably increased. The paint constant-temperature control system device can bring considerable economic benefits for users.
Description
The present invention relates to steel plate oil paint field of coating; specifically; the present invention relates to a kind of novel roll coater paint constant-temperature control system device; described novel roll coater paint constant-temperature control system device can effectively control paint outlet temperature; this system can reduce to greatest extent or stop using paint thinner; reduce diluent consumption, protect environment.
Along with the high speed development of modernization industry, the cold rolling color painted steel strip that the wilderness demand corrosion resistance such as household electrical appliances, building is strong.It is that it has good economic benefit and can extensively adapt to the needs of socio-economic development that color painted steel strip is able to the main cause of high speed development.200910306061.X, 200910161743.6
First, traditional manufactured goods coating process again is become the continuous painting technique that raw material is steel plate by described color painted steel strip, such that be easy to the quality control of surface treatment and application, solves again the painting defect problem being easily generated seamed edge dead angle etc..
Secondly, because the high-speed cruising (the modern coloured coating general 0.15-2.2mm of production line belt steel thickness, plate width is maximum up to 2000mm, and production line linear velocity is maximum up to 240m/min) of production line makes production efficiency be far longer than manufactured goods paint line.
Its three, during coating film curing, the strip steel of continuous coated production line passes through in oven, heat size utilization rate is higher than finished product paint line, during solidification, the solvent of volatilization can collect and be transported to incinerator process, is recycled by heat energy, and total energy consumption only has 1st/to six/5ths of finished product application.Finally, the emission in production is easy to focus on, more environmental protection.
Such as, curing oven waste gas is after burning disposal, and organic solvent content is less than 0.005%, and the oven of finished product paint line is generally extremely difficult to this environmental protection index.Finally, from sheet metal user, although color painted steel strip causes price to increase 18-105% than metal base because of application, but man-hour needed for application and cost of raw and processed materials after eliminating finished product, cost of goods manufactured can reduce 3-10%.The excellent properties that color coated steel sheet tool is so many, therefore, obtains extremely wide application at building field and field of household appliances in recent years.
It addition, production line of armor plate coated paint is generally adopted roll coater, and paint painting is contained in surface of steel plate, enter back into oven drying and shaping.Roll coater is as the core process of coloured coating production line, and its quality directly influences presentation quality and the serviceability of color painted steel strip.Therefore, the technological requirement of coating treatment process is stricter.Roll coater is as the key equipment of color coating line, and a general production line has 4-5 platform roll coater that at surface of steel plate, paint is layered application by technological requirement.Can the thickness for protecting painting layer uniformly and reduces surface defect, and general technology requires that paint must assure that certain viscosity, make the paint abundant flow circuit.Ensure that certain viscosity can reach the film thickness of technological requirement, reach more satisfactory coating quality.
But, on the other hand, owing to general temperature in domestic winter is relatively low, Factory Building environment temperature is generally minimum at about 5-10 DEG C, and at this moment paint viscosity is relatively larger, it is difficult to ensure technological requirement, accordingly, it would be desirable to add substantial amounts of organic diluent in paint to be diluted reaching the viscosity of technological requirement.These diluent are all some high volatile organic solvents, not only can substantial amounts of contaminated environment, health of human body is damaged, and, unit must also strengthen the burning capacity of incinerator for these diluent, is burnt by the diluent of volatilization, to avoid the pollution to environment.
Owing to the consumption of an annual large-scale color coating line only diluent is just up to more than million yuan, and paint temperature cannot be accurately controlled, it is difficult to improve the thickness evenness of coating and improve yield rate, simultaneously, use due to significantly diluent, also production environment is made to be difficult to be effectively improved, the problem that there is energy-conserving and environment-protective aspect.
On the other hand, restriction due to existing roll coater batea structure, paint dispels the heat very fast in batea, paint Temperature Distribution in batea is very uneven, under extreme case, through measuring, the temperature difference is painted maximum up to 10 DEG C along paint roller direction, have a strong impact on the thickness evenness of surface of steel plate paint paint film, causing manufacturing enterprise is the minimum guarantee value ensureing surface of steel plate paint film thickness, must strengthening paint film application thickness, cause paint waste, an annual production line causes entreprise cost to increase up to 3,000,000 yuan because of the impact of the batea temperature difference.
For this, the a set of technology that can reduce or stop using diluent of this area demand, reduce the technology that color coating line paint consumes, require that described technology not only can bring direct benefit to vast color painted steel strip manufacturer, and by the accurate control of paint temperature, the thickness evenness of coating can also be significantly improved, improve yield rate.Simultaneously as the use of diluent and paint is greatly lowered, also makes production environment obtain significantly more efficient raising, reach the purpose of energy-conserving and environment-protective.
For solving above-mentioned technical problem, present invention aim at: a kind of roll coater paint constant-temperature control system device is provided, this system can effectively control the temperature of roll coater paint, makes up to the steady temperature of technological requirement, and then realizes purpose that diluent consume is greatly lowered.
