Owing to comprising polymer film (hereinafter referred to as the film) lightweight of light transmission and easily shaping, therefore extensively utilize as blooming.Wherein, utilize the cellulose esters film of cellulose acylate etc. except being used as picture photosensitive film, be also used as the blooming of liquid crystal indicator.The blooming of liquid crystal indicator refers to such as polarization board protective film or phase retardation film etc.
Main manufacture methods as film there will be a known solution film-forming method.In solution film-forming method, carry out casting films formation process, casting films drying process, stripping process and moistening film drying process successively.In casting films formation process, utilize curtain coating mould to flow out the polymer solution (hereinafter referred to as dope) comprising polymer and solvent from curtain coating mould, the supporter of movement forms casting films.In casting films drying process, enable solvent from casting films evaporation until casting films independently transmits.In stripping process, peel casting films through casting films drying process to be made moistening film from supporter.In moistening film drying process, solvent is made to make film forming from moistening film evaporation.
Casting mold has 1 pair of die lip plate, 1 pair of side plate and runner.1 pair of die lip plate is arranged to the moving direction near supporter and arranges.1 pair of side plate is arranged to extend from the die lip plate of a side across the die lip plate of the opposing party.Runner is surrounded by 1 pair of die lip plate and 1 pair of side plate and forms.On the face orthogonal with the flow direction of dope, runner be formed as moving direction from minor face to supporter extend and long limit to supporter move road width extend rectangle.The stainless steel (such as SUS316L etc.) that this die lip plate and side plate are little and lower relative to solvent solubility by coefficient of thermal expansion is formed.
Curtain coating mould flows out dope from runner exit towards the supporter of movement.Its result, forms liquid pearl between the leading section of the die lip plate of a side and supporter.In casting films formation process, if liquid pearl becomes unstable, then can cause casting films generation uneven thickness.Therefore, the stabilisation by making the leading section sharpening of the respective mode labial lamina becoming the starting point that liquid pearl is formed seek liquid pearl.Inequality refers to uneven state or uneven.
But the Vickers hardness due to SUS316L is that about Hv180 is soft, be therefore difficult to make leading section sharpening by machining.Therefore, have after the leading section of die lip plate arranges the layer (hereinafter referred to as hard layer) than SUS316L more hard, implement the method for predetermined machining.Thereby, it is possible to make the leading section sharpening of die lip plate.As this hard layer, there will be a known the carbide layers such as recorded in Japanese Patent Publication 2003-200097 publication.
