Description
Technical field
The present invention relates to a kind of gas defences to filter cigarette element, especially a kind of filter element and preparation method thereof.
Background technique
Gas defence filter cigarette element (being commonly called as filter cigarette paper or particulate filter in the industry), is the preposition base of filtering type respiratory protection equipment indispensability
Plinth filter element.Its function is that the transmitance of sucking air poisoning smog is greatly reduced in advance, it is ensured that the special filter filled thereafter
Malicious material can give full play to its useful effect.The design for filtering cigarette element should be formed most under the premise of ensuring that transmitance is up to standard
Big valid circulation area keeps inspiratory resistance minimum, uses personnel's physiology of respiration safety requirements to meet to wear.Therefore design is selected
Material is answered nontoxic nonirritant, and keeps physicochemical stability under running conditions.
The filter cigarette element of current domestic production, can summarize the technological deficiency of three aspects: first is that product design structure
Shape is unreasonable；Second is that selection has security risk；Third is that the craftsmanship of production is very poor, can only almost be completed by hand labour,
The wherein huge small-sized canister of civil dosage, because its installation dimension is smaller, contradiction is especially prominent.
1, the preferred design structure vpg connection in filter cigarette element
At present in the filter cigarette element of production, two kinds of modular design patterns can be roughly divided into.
The first design pattern is, a folded bent is bonded in cardboard cylinder frame into similar circular filter paper,
It is composed.It is typical folding and spicing composite structure.Plane filter paper raw material are cut into expanded view rule first by design requirement
Fixed isosceles trapezoid.Its longer bottom, it is prepared Nian Jie with round frame, external cylindrical surface will be folded into；And it is shorter upper
Bottom edge then prepares to ridge is received, forms the middle part hard-core for the product that fold.When folding, it is desirable that using the lower baseline of the trapezoidal filter paper as base
Standard, with the filter cigarette element axial height of design code having a size of spacing, repeatedly positive and negative both direction is folded, and makes section line as saw
Products among tooth form, multiple wedge-shaped filter paper for being connected with each other.Then, with the vertical flat of the upper baseline of isosceles trapezoid filter paper
Split axle line is rotary shaft benchmark, the opposite bending deformation of intermediate product folded, rolls into heart shape as round as possible.Exist again
The enough glues of edge coating, and carefully by the zigzag end of the two sides stringcourse of trapezoidal filter paper, docking cements one by one, is formed this
Filter the central hardware of cigarette element curable type.Finally, by design requirement by this be folded into product among cordate filter paper fill in it is prefabricated
The hard garden Ma Jizhiduan cylinder frame in, the outer ledge of the intermediate product is pullled the cardboard garden barrel part for having been coated with glue
On inner wall, compacting is cemented.Until after glue solidification, detecting breakage and loophole, supplement gluing sealing.This kind of design pattern generates
The problem of be filter paper material being unevenly distributed on working face, density significant difference.In dense portion, material is concentrated, resistance
Bigger than normal, the valid circulation area for utilizing reduces.This defect is solid especially serious in the middle part of the filter cigarette element that viscose glue is assembled.And
In the part that filter paper material is sparse, then the air-flow carried is easier to puncture, and penetrance is enabled to increase.In production repeatedly it is folding can
The fatigue rupture of filter paper microcellular structure can be caused, leaves secret worry for the use of element.
Second of design pattern, substantially and folding and spicing structure.Difference be need not prefabricated garden tubular frame, built up
Filter paper shape also not like heart-shaped.The envelope of design requirement element entirety answers filter paper centre system cylindrical, and placed in the middle
Part, should be the zigzag wedge that multiple plane filter paper are formed, their different lengths and be connected, and wedge-shaped top is two
Small filter paper plane convergence at straight line, it is parallel to each other.It, must be right according to the identical size of canister internal diameter by design code
Product is cut among the wedge built up, forms the cylindrical envelope of element entirety.Then, to every on enveloping surface
A end edge coats enough glues, one by one sealing docking.Finally, the cylindrical surface is wrapped up with the strip filter paper for being coated with glue
Tightly, bundle jail is tightened.After cured, detection is damaged and loophole, supplement gluing are made up.
Therefore second of design pattern eliminates folded bending requirement, and point of filter paper material compared with the first
Cloth is also relatively uniform.But do not have effigurate hard frame, the product shape for enabling bonding combined cannot be stablized, and easily distort.Carry,
It may cause secondary damage in storage and installation process.As a same reason, multiple folding when production, it is also possible to keep filter paper micro-
Pore structure generates destruction, and security risk still exists.
2, secondly in terms of the material selection of filter cigarette element design
The country is used as basic material, Shao Liangzhuan using PP (polypropylene) fabric nonwoven cloth in the filter cigarette element overwhelming majority of production
Glass filter paper is just used with filter cigarette element.But no matter raw material why, be all that paper mill or thermal insulation material Chang Deng enterprise produce
Plain paper or non-woven fabrics.Fiber raw material used in papermaking does not consider that the physiology of respiratory protection or technology are wanted specially substantially
It asks, the manufacturer as Protection Product only passively receives the existing product speciality and quality level of paper-making industry.Make with filter paper
In the case where making material, the structure design of filter cigarette element is restricted, and " structure type for folding plus being bonded " is caused to become
Only selection enables above-mentioned problem without solution.On the other hand, this material of PP, which there is itself, is not suitable for the one of canister
A little inherent defects.Since filtering type respiratory protection equipment dosage is huge, protection object is again complicated, and it is serious more to highlight problem.
The adopted reason of PP non-woven fabrics is mainly that it is easy to fold.But the diameter of PP fiber (about 0.25 μm) is extremely difficult to ultra-fine glass
The fineness of glass fiber (diameter is about 6~7nm), keeps hole caused by PP non-woven fabrics fiber larger, transmitance is not easy to reduce.If right
PP filter cloth thickeies compacting, though its low transmitance can be decreased slightly as, but increases resistance, it is more difficult to follow.PP nonwoven cloth material it is another
Short slab is non-refractory.Only 165~173 DEG C or so of its fusing point, limit its scope of application in canister.Only to prevent an oxygen
For the canister for changing carbon poisoning, when providing to carry out routine test with 1% to 1.5% concentration by standard, reaction temperature in tank
Degree may be up to 300 DEG C or more, and filter cigarette paper directly can be burnt hole by the heat for including in the air-flow by filtering cigarette paper, enable filtering
Disabler.There are one fatal defects for PP nonwoven cloth material, are that there are certain wellabilities to oiliness material, when it is longer
Between contact mist of oil class toxic agent when, it may appear that toxic agent " gets over " danger of filter cloth, is really serious security risk.
3, finally in terms of the craftsmanship of design
The filter cigarette element design structure of former " folding bonding combination ", before the reform and opening-up that economic and science and technology falls behind, by
In low price, labour is abundant, a kind of selection for reality of can yet be regarded as.But this design can only almost be completed by work by hand, limitation
The uses of many modern crafts means, inefficiency, the wasting of resources, industrial refuse are more.Control of product quality difficulty is big, with
The continuous rising of cost of labor, enable enterprise development have difficulty in taking a step.
Problem above makes the original for filtering cigarette element be designed to the structural short slab of supply side of industry, and innovation is carried out to it and is changed
It removes from office very necessary.
