Embodiment Construction

[0047] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0048] Prior to this, in order to understand the present invention, it is first necessary to understand the properties of SAP and SAP dispersion slurry, and the properties of non-woven fabric substrates.

[0049] The technology of coating high-viscosity and good fluidity slurry on a smooth film or metal foil is already a mature technology in the industry. This technology is roughly divided into mold coating, curtain coating and nozzle coating. There are two types of extrusion methods and coating head overflow methods with coating head slots. As the method of coating head, lip type direct coating head, intermittent direct coating head, intermittent reverse coating head, bottom area reverse roller coating head, direct gravure coating head, kiss coating Coating heads, extrusion coating heads, etc., and coating heads for various purposes ha...

Abstract

A coater for dispersed slurry capable of coating coated dispersed slurry on a nonwoven cloth-like base material while bringing the slurry into contact with the material, comprising a net conveyor for transferring the nonwoven cloth-like base material, a supply means for supplying the dispersed slurry onto the net conveyor, and a coating roll for forming a coating layer of a specified thickness by pressing, from the upper side thereof, the dispersed slurry supplied onto the nonwoven cloth-like base material, wherein this coating roll is allowed to come into direct contact with the dispersed slurry on the peripheral surface of the nonwoven cloth-like base material or allowed to come into contact with the dispersed slurry through a film provided therethrough.

Description

technical field [0001] The present invention relates to a kind of coating device that utilizes coating roller to make the dispersion slurry that makes solid particle disperse in dispersion medium be coated on the surface of the base material that advances continuously, relate to a kind of improved coating device especially, whether it is Whether it is a dispersion slurry that is easy to adhere to the surface of the coating roller, or a dispersion slurry that is easily precipitated and dispersed in a solid phase component, the dispersion slurry can be stably and uniformly coated on the continuously moving substrate superior. [0002] As an example of the above-mentioned dispersion slurry, there is a dispersion slurry in which a superabsorbent resin (hereinafter referred to as SAP) is dispersed in a dispersion medium. By applying this dispersion slurry to a non-woven fabric substrate, a thin layer absorber. Background technique [0003] With the ultra-thinning of absorbent p...
