Description
Technical field
The present invention relates to mesh screen, specifically a kind of abrasion-proof screen and preparation method thereof.
Background technology
So-called screen cloth is different and general web-shaped product.But have strict serial mesh size.And have to object
Grain be classified, screening function meet industry, mechanism, standard approve web-shaped product.Screen cloth does not say " mesh number ", " mesh number "
It is people to describe a kind of custom of screen cloth, is difficult to overcome for the moment.Screen cloth is different from general web-shaped product, is exactly that it has strict
Mesh size, rather than " mesh number ".Screen mesh size is not isolated, and it is made up of serial mesh size, in order to be classified
Screening.
It is divided into natural silk bolting cloth, wire mesh screen and the class of synthetic fibers screen cloth three by raw materials used.
1）Natural silk bolting cloth selects mulberry silk full reeled yarn tissue, half reeled yarn tissue or the plain weave group of different fiber numbers according to specification
It is made into, knits mode processed similar to eyelet fabric.Mesh number it is few when with full reeled yarn tissue, when mesh number is more, with half reeled yarn or plain weave.
The specification of natural silk bolting cloth have 4~62 holes/centimetre, mostly for Grain Industry screening, also be available for emery wheel emery cloth factory screening difference slightly
Fine sand is used.
2）Metallic sieve is by certain technical method to be fabricated to web-shaped product to wire.With copper wire, stainless steel wire,
Iron wire, steel wire are made into for raw material.Wire diameter is mostly at 4~0.025 millimeters.It is general to use plain weave, twill, seat shape weaving square
Method.Metallic sieve eyelet is clear correct, wire side is flat very, has high temperature resistant, a characteristic such as wear-resisting, and stainless steel mesh can also be corrosion-resistant.Cause
This, in terms of metallic sieve is used for powder screening and oil strain.
3）Synthetic fibers screen cloth has two kinds of long filament and the palm fibre of polyamide fibre or terylene.Long filament 15~30 denier monofilaments, screened port
Surface is smooth, is conducive to filtering.Fabric tissue can use, gentle plain weave in side etc., specification have 19~104 holes/centimetre.It is be used as print more
Flower tulle, integrated circuit printed substrate is manufactured, it can also be used to screen the relatively fine particles such as the magnetic of display tube fluorescent powder and tape.
Monofilament screen cloth is raw material with thicker polyamide fibre monofilament, a diameter of 0.55~0.1 millimeter, and fabric is generally plain weave seat shape tissue, is used for
Ore dressing, filter paper pulp, conveyer belt etc..Synthetic fibers screen cloth has non-corrosive, it is corrosion-resistant the features such as, part metals sieve can be replaced
Net.
Metallic sieve can be divided into：Stainless steel square hole pattern, stainless steel fine groove seat type net, all kinds of screen clothes of stainless steel crimped wire mesh etc.
Stainless steel square eye net is widely used in the screening of solid material, screening, the filtering of liquid.Be related to many industries, such as it is chemical
Industry, food and condiment trades, mining industry, pharmacy, papermaking, metal dust manufacture, chemical fertilizer industry.Stainless steel fine groove seat type net is not
The steel net that becomes rusty is applied to gas, liquid filtering and the separation of other media, is widely used in precision pressure filter, fuel filter
The industries such as device, vacuum filter.
Manganese steel screen cloth：Manganese steel is a kind of anti-manganese steel of high intensity, be mainly used in needs withstand shocks, extrude, material abrasion
Etc. bad working environments condition, failure mode is based on attrition, portion fractures, deformation.Abrasion is divided into three kinds：Metal component surface
Between the fretting wear that contacts with each other and move；The abrasive wear of other metal or non-metallic material strike metal surfaces and flowing gas
Body or liquid contact caused erosive wear with metal.The anti-wear performance of abrasion-resistant stee depends on material in itself, and Development of Wear Resistant Steel then exists
Show different wearabilities under different working conditions, material could determine its anti-wear performance with both working conditions in itself.
Screen cloth is braiding to wire, the punching stretching of metallic plate, is made by certain technical method and reticulates production
The classification of product greatly.And the screen cloth wearability of this structure is not very good, it is easily damaged, is lost when screen cloth is used when use
Greatly, safeguard also very inconvenient.

Throwing power greatly reduce, it is impossible to discharge drilling cuttings, the present invention directly replaces existing screen cloth by the screen cloth of pouring type, it is to avoid
The problem of screen cloth tension force is inadequate, if screen cloth tensioning dynamics is not enough, so that causing screen cloth to tremble, generally along screen periphery or bound edge
It is broken or damages at press strip.Vibrating motor turns to mistake when debugging vibrating motor steering, and site operation personnel is according to conventional list
The use experience of shaft vibration sieve or linear vibrating screen, it is believed that as long as drilling cuttings is goed ahead, but the method is not particularly suited for translation
Elliptically vibrating screen.If inwards rotating, though vibrating deflection is also 45 ° forward, drilling cuttings has what is rolled backward motor error
Power, the speed that at this moment drilling cuttings is migrated forward is many slowly, and the residence time is long on screen cloth, and resulting even in drilling cuttings can not discharge.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
, can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses
Make a variety of changes.
