Description
Technical field
The present invention relates to casting machine field, particularly a kind of casting machine additional wet film static air exhausting device.
Background technology
Casting machine is widely used in cast film molding art.The tape casting technique of application is non-aqueous tape-casting moulding process at present, the most traditional casting technique.The most traditional non-aqueous tape-casting shaping is the most ripe, it is widely used at ceramic field, the solvent that solvent system is conventional has: toluene, dimethylbenzene, butanol, ethanol, methyl alcohol, trichloro ethylene etc., traditional flow casting molding is obtained in that high-quality ceramic substrate, but the organic solvent owing to being used has volatility, toxicity and the factor such as on the high side, people begin attempt to make solvent with water and replace organic solvent.
Aqueous tape casting forming have cheap, non-toxic meet environment protection emission requirement, nonflammable, reduce production process and the explosion-proof Regulation Cost of equipment is low etc. that advantage causes concern and studies, but also due to there are some intrinsic unsurmountable problems: 1. water evaporation rate is low, rate of drying is slow, it is impossible to realize curtain coating industrialized production at a high speed；2. the binding agent needing higher amount could realize blank strength, this problem bringing again sintering coke discharging；3. hydrogen bond causes ceramic powders reunion to cause flocculation cannot form the slurry required for the stable flow casting molding that levelability is superior, causes hardly resulting in the curtain coating material strip that thickness and precision is high；4. slurry is sensitive to changes in process parameters, is difficult to the fine and close smooth ceramic membrane of molded surface, and curtain coating blank strip surface easily produces the open defects such as a large amount of pin hole, cracking, pit.5. base substrate combines insufficient, is dried cracking easy to foaming, and base substrate fragility is big, flexible deformation；6. defect causes stress to concentrate, and causes sintering cracking.For the 2nd and the solution technical scheme of the 3rd, my company mentions in Chinese patent one NFC Magnetic Substrate aqueous casting slurry applied for and preparation method thereof and a kind of NFC Magnetic Substrate (application number: 201410424887.7), and my company has developed the casting machine that a kind of cast film thickness precision is high, therefore the biggest obstacle that aqueous tape casting occurs at present is to realize the high speed curtain coating industrialized production application of high-quality base substrate, the micro-pore within surface pinholes that non-conforming causes mutually and base substrate cannot be solved, the high speed evaporation that cannot break through water realizes industrialized production application, high tensile blank strip cannot be realized to ensure that coiled material following process clicking technique produces.
Due in curtain coating dry run, grope to find that in dry run, gas overflows from upper surface, middle lower floor constantly diffuses up according to psychrometric difference, need to do is to the liquid migration velocity balancing upper surface gas overflowing speed with middle lower floor, ensure gas overflowing passage as much as possible simultaneously.Additionally in preliminary process, in slurry, solvent strength is very big, utilizes itself and the concentration difference in environment just can reach higher evaporation rate, and the later stage is contrary.Thus use low early and high after gradient drying system.And higher temperature makes surface and internal solvent quickly volatilize, cause upper surface skinning to make gas overflowing passage close, and the gas of the volatilization of inside do not have overflow channel, cause cracking and thickness unstable,
Simultaneously as the effect of washing on surface influences whether that slurry arrives thickness change and the fluctuation of blank strip in dry run；Chinese utility model patent, the entitled casting machine (application number: 200920055522.6) with microwave heating drying device, this utility model patent uses multiple microwave heating box side by side, each temperature adding hot tank is controlled by temperature control system, but germ band is in dry run, the gas evaporated, discharged curtain coating drying tunnel the most timely, so that the temperature in casting machine drying tunnel is gradually lowered, so that germ band is heated uneven, affect product quality, and use and multiple add hot tank, add equipment cost and power consumption cost, microwave heating box easily damages, add the cost of overhaul undoubtedly, waste the working time.
Therefore for the feature of water system formula dry run, the aerodynamics layout within baking zone and heterogeneity phantom and atmosphere backflow concentration ratio need to be readjusted, design and produce a set of more reasonably curtain coating drying tunnel additional cushion current stabilization and adjust window, improve the dry bottleneck of tradition casting machine, make shorter casting machine device possess more efficient drying efficiency, thus realize water system formula high speed curtain coating on steel band casting machine.
