Definitions

  • This invention can simultaneously coat one or more than one layer on a moving web with high uniformity, and is suitable for silver salt or non-silver salt photo- sensitive materials production. It is also suitable for other productions, which require one layer or more than one coating layer such as double coating non-carbon tissue-paper.
  • the photographic industry there are used black-and white and colour films or papers. All those products need a coating method, which can coat various liquid components continuously on the paper, film, or cloth with high uniformity. Some products need coating one layer, others need coating two layers, three layers, four layers, or more layers. For example, the negative colour films need coating twelve or sixteen layers. According to the different products requirement, the minimum thickness of the wet coating layer is 0.010 millimetre, and the maximum thickness is 0.200 millimetre. It is a kind of high precise coating technique, so that the standard deviation of the non-uniformity should be less than ⁇ 1%, when the width of the coating web is more than 1,000 millimetres.
  • the thickness of wet coating layer h has the mathematical relation as following: which has been described by DERYAGIN B. T. AND LEVI S. M., FILM COATING THEORY, p.47, FOCAL PRESS, LONDON, 1964.
  • the velocity of this coating method is usually controled at 4 to 18 metres per minute, and gets the thickness of wet coating layer from 0.120 to 0.260 millimetre.
  • this coating method can coat only one layer by one pass, and it is difficult to control the accurate coating thickness. Therefore, it has those shortcomings such as: the mono-coating layer, the thicker layer, the lower speed, and flow-down of the coating liquid, and can not satisfy to produce colour films and papers.
  • This bead coating method can simultaneously coat at least more than one layer, and get more thiner wet coating layers.
  • the velocity of this coating method is usually controled at 40 to 150 metres per minute, and gets the wet coating thickness from 0.090 to 0.160 millimetre. Therefore this bead coating method has notable advantages such as: the multiple coating layer, the thiner layer, the higher coating speed, and the accurate control coating thickness; and has been widely used to produce colour films and papers with high-quality.
  • the coating bead is suspended between the lip of the slide hopper and the moving web, and there are two independent radius of curvature R 1 , R 2 , existing on the upper and lower surface of the bead.
  • the upper radius of curvature R 1 , the thickness of wet coating layer h, the viscosity of the liquid ⁇ , the surface tension of the liquid ⁇ , the coating velocity U have the mathematical relation as following:
  • the upper and lower radius of curvature R 1 , R 21 the pressure of upper space P 1 , the pressure of lower space P 21 the density of the liquid p, the acceleration of gravity g, the surface tension of liquid ⁇ , and the thickness of suspending bead h 0 , have the mathematical relation as following: which has been described by Wang Zhongjun, CURRENT THEORY AND PRACTICE OF COATING AND DRYING TECHNIQUE, p.32 to 41, First Film Factory, The Ministry Of Chemical Industry, 1973.
  • the bead coating method has some unavoidable shortcomings as following:
  • D. J. Hughes and J. K. Greiller had developed a new kind of free-falling vertical curtain coating method, which resembles the bead coating method to get a plurality of surperposed layers under the laminar-flow condition, and is similar to the curtain coating method to apply in the painting field.
  • This coating method is allowed to use a liquid composition of higher viscosity from 5 to 100 mPas (1 mPas - 1 c p ).
  • the liquid curtain will be accelerated by gravity at a rate less than acceleration in free falling, and the web is moving on the horizontal direction at the coating speed as far as 0.3 to 3 folds of the velocity of free-falling vertical curtain near the surface of coating web.
  • this coating method can avoid those defects such as: “streak”, “pencil line”, and “interruption by splice” frequently found in the bead coating method, and it is more suitable for the production of the colour film and paper.
  • the free-falling vertical curtain coating method also has some shortcomings as following:
  • This invention develops a new kind of vertical drawing curtain coating method, which can simultaneously coat one or more than one layer on the moving web with high uniformity, and is suitable for silver salt or non-silver salt photosensitive materials production. It is also suitable for other production, which requires one layer or more than one coating layer.
  • This new coating method can suit with the coating thickness of covered range both of the bead-co: Ling and the free-falling curtain method, and can avoid those defects such as: "pencil line”, “streak”, and “interruption by splice” or those troubles such as: “thicker edges” and “disturbance by air current” in the free-falling curtain coating method.
  • the new coating method and device contain three main parts: the higher uniform equal-flow distributing coater, the vertical drawing short-curtain, and the parallel rotated coating roller and moving webs; therefore this new coating method may be named as "vertical drawing curtain coating method", which is described as following:
  • the coater is not situated above the coating web and roller but is situated at the upper flank space of the coating roller and web, which is the main difference of this invention as compared with the free-falling curtain coating method. Therefore, the height of liquid curtain may be reduced to the more or less than 50 millimetres forming a more stable short-curtain, which may be adjusted in the height range from 0.5 millimetre to more or less than 50 millimetres.
  • the coating roller and the web are rotated at the same direction and the liner speed of the rotation is greater than the free-falling velocity, the short-curtain will be drawn and much reduced in thickness. According to the different product's requirement, it may be adjusted that the drawing ratio is from 1 fold to 20 folds to get the wet coating thickness h from 0.020 millimetre to 0.240 millimeter.
  • This coating method can coat the liquid to the uneven surface, such as: cloth, screen, and embossed paper.
  • the vertical drawing curtain is the key of this coating technique in this invention.
  • the falling velocity of the curtain is approximate to 1 metre per second.
  • the liner speed of the coating roller and web will be 5 metres per second, which is equal to 300 metres per minute contenting the requirement of the major factories.
  • the coating speed is usually less than 180 metres per minute, which is equal to 3 metres per second.
  • the height of the curtain may be reduced to 5 millimetres to 20 millimetres, and the coating speed is at 0.3 to 3 metres per second, which is equal to 18 to 180 metres per minute.
  • the drawing short-curtain has higher stability, which can avoid thoses troubles such as: “thicker edges” and “disturbance by air current” in the free-falling curtain coating method. And it has the sufficient height to pass through any splice such as: flying splice, butt splice , welding splice, or mechanical splice, to avoid those defects such as: “pencil line”, “streak”, and "interruption by splice” in the bead coating method. Therefore, this new coating machine may be equiped with an automatic splicer of any type, which omits the voluminous accumulator, simplifies the web cleaning system, and makes for the traditional coating machine a great advance.
  • this new coating method can use a more larger variation of liquid viscosity in the range from 2 mPas to 1,000 mPas.
  • the suitable viscosity of coating liquid may be varied from 5 mPas to 50 mPas usually not exceeding 100 mPas.
  • the suitable viscosity of coating liquid may be varied from 5 m?as to 500 mPas usually not exceeding 1,000 mPas.
  • this new coating method can use a more viscous and more concentrated liquid composition, which will get a thiner coating layer, drying under a lower temperature, requiring less drying capacity , saving the energy and reducing the cost of production.
  • this new coating method is also different from the hot-melting coating and the extrusion coating method, used for manufacturing the adhesive tape, the resin coated paper, or described in the European Pat. 31,301 A.
  • the melting liquid composition is extruded from a coater to form a liquid curtain which is drawing and gelling between the polished cooling roller and the moving web, so that the hot-melting coating and the extrusion coating methods can not coat those liquid compositions with low viscosity, low gelling strength, or without gelling property.
  • the liquid curtain impacts and adhesives on the surface of the moving web, after drawing and reducing the thickness of liquid coating layer, and then slowly gelling in a chilling chamber, otherwise the new coating method can coat those liquid compositions without gelling property such as used in the non-silver salt photo- sensitive materials production.
  • the vertical drawing curtain coating method is suitable for various coating layers of the silver salt photo-sensitive materials production such as: subbing layer, antihalation layer, filter layer, black and colour film or paper, cine- film, X-ray film, aerial-film, lithographic film, micro-film, holographic micro-film etc.; and is also suitable for non-silver salt photo-sensitive materials production such as: diazo-type micro-film, diazo-type printing paper, red-mask stripping film, electrographic paper (or Electrofax), pressure sensitive copying paper etc.
  • the silver salt photo-sensitive materials production such as: subbing layer, antihalation layer, filter layer, black and colour film or paper, cine- film, X-ray film, aerial-film, lithographic film, micro-film, holographic micro-film etc.
  • non-silver salt photo-sensitive materials production such as: diazo-type micro-film, diazo-type printing paper, red-mask stripping film, electrographic paper (or Electrofax), pressure sensitive copying paper etc.
