Description
Technical field
The utility model relates to filter filtration material and the manufacturing installation thereof that is filtered the contained particle of gas for trapping, and particularly relates to the former material of filter material that can trap this particle to being configured to and carries out the filter filtration material that pleat mace processes.
Background technology
In the past, as the filter filtration material of use in the dust free room etc. of factory of manufacturing semiconductor, liquid crystal, be known to filter filtration material 100(as shown in Figure 5 with reference to patent documentation 1).This filter filtration material 100 is by trapping to being configured to that the former material 200 of filter material that is filtered the contained particle of gas is crooked in many places to be formed folded shape and form.
This filter filtration material 100 comprises by making the crooked a plurality of bend 100a that form of the former material of filter material 200, configuring a plurality of flat part 100b of forming and for keeping a plurality of intervals maintaining part 300 at adjacent flat part 100b, 100b interval each other in the relative mode in the region except bend 100a in the former material 200 of filter material.
This interval maintaining part 300 is formed by a plurality of ribs (bead) 300a of portion, and flank 300a forms by opening compartment of terrain adhesive-applying (PUR etc.) in two face overhead of the former material 200 of filter material.Specifically, interval maintaining part 300 is by the flank 300a that is formed at each flat part 100b being engaged with each other and being formed between each flat part 100b between each flat part 100b in the one side side at the former material 200 of filter material and in another side side.That is to say, interval maintaining part 300 is formed between each flat part 100b in the one side side of the former material 200 of filter material and between each flat part 100b in another side side.
In addition the interval maintaining part 300 that, is formed on the interval maintaining part 300 of the former material of filter material 200 one side sides and is formed on another side side is configured to across flat part 100b and can be not overlapping.Specifically, the interval maintaining part 300 of the one side side of the former material 200 of filter material is opened compartment of terrain along bend 100a sky and is disposed a plurality ofly, and the interval maintaining part 300 of the another side side of the former material 200 of filter material is configured between the interval maintaining part 300,300 of adjacent one side side.Thus, compare with form the situation that flank 300a forms interval maintaining part 300 in the whole region of flat part 100b, the use amount of bonding agent reduces.
In addition, sometimes filter filtration material 100 as described above is applied to the power that the makes flat part 100b interval constriction each other such power of the direction compression filter filter material 100 intersecting with flat part 100b (specifically, along) (being also denoted as below the power on compression direction).For example, the in the situation that of in filter filtration material 100 is housed in bag, sometimes becomes and utilize bag filter filtration material 100 to be applied with to the state of the power on compression direction.In addition,, in the situation that become the mode keeping filter filtration material 100 of the state of approximate horizontal with flat part 100b, become and utilize deadweight filter filtration material 100 to be applied with to the state of the power on compression direction.
And, if maintain the state that filter filtration material 100 is applied with to the power on compression direction, likely make filter filtration material 100 be fixed into the narrower state in flat part 100b interval each other.
Specifically, in filter filtration material 100 before power on being applied in compression direction, as shown in Fig. 6 (a), utilize interval maintaining part 300 keeping flat part 100b interval each other, but by filter filtration material 100 is applied to the power on compression direction, as shown in Fig. 6 (b), the interval maintaining part 300 of the another side side of the interval maintaining part 300 of the one side side of the former material 200 of filter material and the former material 200 of filter material can approach along compression direction.Thus, produce distortion in each flat part 100b, each flat part 100b interval each other narrows down.And, if filter filtration material 100 is applied with to the state continuance of the power on compression direction, go down, likely the shape of each flat part 100b can not revert to state before distortion (filter filtration material 100 is applied to the state before power on compression direction) and be fixed into the narrower state in flat part 100b interval each other.
Like this, if each flat part 100b interval each other narrows down, the size along in the direction of compression direction of filter filtration material 100 becomes and is shorter than desired size.Therefore, for example, while forming filter unit filter filtration material 100 being arranged in template, between filter filtration material 100 and template, produce gap, become the bad filter unit of seal.In addition,, because the interval between each flat part 100b narrows down, also likely cause the pressure loss of filter filtration material 100 to become large.
