摘要:
A coated film drying method for drying a film which is coated on a surface of a web while the web is running through a tunnel-shaped dry case having a web entrance and a web exit, comprising the steps of: blowing dry air toward a surface of the coated film through an outlet port which is provided with a porous distributor; and sucking the dry air through an inlet port which is disposed at a position downstream or upstream of the position where the dry air is blown out and on the same side as that on which the outlet port is disposed relative to the coated film, so that a stream of the dry air which flows in a direction parallel to the running direction of the web is formed across the entire width of the surface of the coated film.
摘要:
The coating construction has flexibility corresponding to the number of layers of multiple coating layers, by which a multilayer coating film can be produced with small film thickness without adherence of dust to a film surface, a drying fault such as unevenness induced by drying-wind on the film surface, or a coating fault such as a level variation and a streak. The multilayer coating film has a coating surface state of high quality with coating thickness deviation of 3% or less. A coating device is constructed in which at least a feed roller, a coater and a dryer are integrally incorporated in a casing, and the coating device is given a function as an independent device, whereby the production apparatus of the multilayer coating film can be constructed by only appropriately placing as many coating devices as the number corresponding to the number of layers of the multiple coating layers formed on a web between a delivery device and a winder.
摘要:
According to the present invention, since the gravure roller with no load has a radial run out of 15 μm or less in all places of a pattern part in which cells are formed (the gravure plate cylinder) on the surface of the gravure roller, liquid accumulations (beads) are hardly affected by the radial run out of the roller surface, thereby making it possible to prevent coating nonuniformity.
摘要:
According to the present invention, a region in the vicinity of a width edge of a running substrate is locally heated, so that it is possible to eliminate irregular coating portions which may be caused by elongation and wrinkles at the edges of the web and also possible to provide the heating device at a low cost.

An additive for cholesterol-containing food, containing a rice bran component and/or a derivative thereof as an active ingredient, a method of using same, and food treated thereby; and a process for producing mayonnaise controlled in the rise of a blood cholesterol level, or the absorption of cholesterol. A method of decreasing the effect of cholesterol contained in food on a living organism, for example, controlling the rise of a blood cholesterol level by adding to cholesterol-containing food a food additive capable of forming a complex with cholesterol, such as an extract of a rice bran component, .gamma.-orizanol (.gamma.-OZ) which is a mixture of esters of ferulic acid with various alcohols prepared by refining said extract and/or a derivative of a rice bran component, thereby forming a cholesterol complex of the food additive, whereby the cholesterol contained in food becomes nonabsorbable by a living organism or can be removed therefrom.

In an aspect of the coating method according to the present invention, the lower limit decompression degree PS1 at which a seam trouble occurs is obtained from the formula of the viscocapillary model. According to the aspect of the present invention, coating is performed by setting the Pb so as to satisfy PS1
摘要:
The present invention provides a process for producing an antireflection film comprising applying, using a slot die, a coating solution onto a web which is backed up by a back-up roller and runs continuously to form at least one layer which has a thickness of 200 nm or less in a dried state and has a refractive index lower than that of the web. The slot die has an edge lip downstream of the running web which has a land length along the running web is 30 to 100 μm, and the space between the edge lip of the slot die upstream of the running web and the surface of the web is set to be 30 to 120 μm larger than the space between the edge lip of the slot die downstream of the running web and the surface of the web.
摘要:
A producing method of a coated film is provided and includes: coating a coating solution that contains a light-transmitting resin and a solvent on a support and, subsequently applying first and second drying steps for drying a coated coating solution. The first drying step is carried out in a drying zone where the maximum wind speed on a surface of a coated layer is 1 m/sec or more, and the second drying step is carried out in a drying zone having a temperature of 50° C. or more higher than a temperature in a zone where the first drying step is carried out.
摘要:
A coating method includes the steps of: providing a pressure reducing chamber and a slot die adjacent to each other from an upstream side in a moving direction of a base material, providing a backup roller so as to face the slot die, and coating a coating liquid on the base material using the slot die, the base material being subjected to tension by the pressure reducing chamber, wound around the backup roller and continuously moved, wherein when A=η×V×h×L×1/D3, the coating liquid is coated under 2 N/m2≦A≦700 N/m2, where η is coating liquid viscosity, V is a coating speed, h is a coating film thickness in a wet state, L is a slot length, and D is a slot width.
