Abstract
The invention discloses a filter element for injection moulding and an application thereof. By adopting an appropriate filter material, the defects that the appearance is poor and the filtering performance is reduced as resins overflow in an injection moulding processing process can be overcome. Besides, by adopting the filter material, the incidence of unqualified products in production can be greatly reduced.
Description
Technical field
The present invention relates to a kind of filter element for injection moulding, be mainly used in automobile filtration art.
Background technology
For existing filter core (filter element for injection moulding), due to filter material thickness, cause in the time of injection mo(u)lding, part resin is from overflowing between mould and filter material.Certain a part of reason is to select improperly due to injection mo(u)lding resin, or mold for forming is due to long-time use, causes the reasons such as distortion that moulding resin is overflowed.Reason is but more because the filter material of selecting is improper, while causing injection mo(u)lding due to by mould pressurized, filter material do not recover in time or thickness own just not thick, thereby the resin in mould overflows from space.And resin overflow can affect the outward appearance of product, and can increase the defective work incidence in filtration crushing and the production of material.Filtering industry, especially air conditioner for automobile cleaner use injection mo(u)lding is many, so such filter element for injection moulding must solve the problem that resin overflows.
Although as related to a kind of manufacture method of air cleaner of injection mo(u)lding in Chinese publication CN1474713, the running resistance of still not improving outward appearance, minimizing defective work incidence and the filter core of product remains unchanged very high.
Summary of the invention
The object of the present invention is to provide filter element for injection moulding of a kind of good appearance, low pressure loss and uses thereof.
Filter element for injection moulding of the present invention is 44g/cm when measuring pressure
2, METHOD FOR CONTINUOUS DETERMINATION 10 minutes, this filter core filter material thickness reduction used rate between 0.8～5%, preferably 1～2%, the resin length that surface of filter medium overflows is not more than 5mm, is preferably not more than 3mm.If wherein filter material thickness reduction rate is less than 0.8%, illustrate that filter material is harder, be difficult to compressive deformation, when this filter material injection mo(u)lding, be easy to overflow resin; If filter material thickness reduction rate is greater than 5%, the very easy compressive deformation of filter material is described, owing to recovering difficult, when injection mo(u)lding, be also easy to overflow resin.And overflow for resin, it is short that its length has length to have, and in general, the resin length that surface of filter medium overflows is greater than 5mm, can have impact to the crushing of filter core (running resistance); And the resin length of overflowing is less than 5mm, be especially less than 3mm and be fine, do not affect exterior quality.The resin length that the surface of filter medium here overflows refers to that the resin overflowing from resin edge inboard covers the extreme length of effective surface of filter medium.
Filter material material of the present invention is nonwoven, and its thickness is that 0.3～0.8mm, grammes per square metre are 15～100g/m
2.Filter efficiency and running resistance at the nonwoven of above-mentioned thickness range are suitable, and the most applicable injection molding; And grammes per square metre is lower than 15g/m
2, efficiency is low, and when injection moulding, filter material is easily damaged; If grammes per square metre is greater than 100g/m
2, efficiency is to have improved, but can bring the rising of running resistance simultaneously and be difficult to the problem of injection molding.
Filter element for injection moulding of the present invention, has installed the integrated clathrate barrier that prevents that foreign matter from entering additional.Because filter element for injection moulding is used in automobile filtration, industry is many; such as air-conditioning filter cleaner; in use; for prevent hard and have the foreign matter of water caltrop to enter air-conditioner filtering system after destroy soft cleaner (filter material); generally install the barrier of a clathrate or other shape additional in cartridge surface; preferably clathrate barrier, so just plays a protective effect.Certainly, this barrier is the performance that can not reduce filter core.
For integrated definition, refer to compared with conventional filter core processing method, do not need good rear passing through on sale to paste the processing methods loaded down with trivial details and consuming time such as length frame material, but be directly pressed into cleaner by forming machine.
For this filter element for injection moulding, in order to improve filter area, filter material is through the processing that gives a discount.Because through giving a discount after processing, although take same volume (volume), through giving a discount after processing, filter area can increase by 2～5 times, and performance can not decline substantially simultaneously.Especially in automobile industry, in order to improve occupant's comfortableness, inner space of vehicle is brought up to maximum as far as possible, but can not increase the overall volume of automobile, can only be by reducing the volume of automobile inner part.Such as air-conditioning system possessive volume reduces, thereby must reduce the volume of cleaner (filter core), so the processing that gives a discount is necessary.
Filter element for injection moulding of the present invention, is mainly used in automobile filtration art.
Filter element for injection moulding good appearance of the present invention, has good low running resistance, by selecting suitable filter material effectively to control the incidence of defective work in the process of producing filter core.
Detailed description of the invention
In the present invention, the method for testing of various performance parameters is as follows:
(1) thickness reduction rate: the circular filter material that is first 17cm by 5 diameters is superimposed successively, then adopt and Japanesely must measure its original depth by happy TECLOCK SM-114 analyzer processed, then apply in the above the weight of 10kg, exert pressure as 44g/cm
2and continue after 10 minutes, to measure again its pressurized thickness, finally calculate thickness reduction rate=(original depth-pressurized thickness)/original depth of filter material.
(2) thickness: adopt Japanese must mensuration by happy TECLOCK SM-114 analyzer processed.
(3) grammes per square metre: take 100cm by disk sampler
2circle (5), on balance, take respectively weight M1, M2, M3, M4, M5 (unit: g), finally calculate the grammes per square metre (unit: g/m of filter material
2)=(M1+M2+M3+M4+M5) * 100/5.
