Abstract

The invention relates to a preparation method of glass fiber filtering screen, which is that a glass melting furnace driven by program control and frequency-modulated motor does the reciprocating movement horizontally, and winding and wire drawing are carried out by rotating fiber glass roller. The reciprocating movement in horizontal way of the glass melting furnace driven by program control and frequency-modulated motor can be divided into three steps: step one: uniformly reciprocating movement is done to form lower surface later of diamond grid; step two: circulation movement with speed change is carried out to form a interlayer; step three: uniformly reciprocating movement is done to form upper surface later of diamond grid; the invention has planarizing surface with effective bonding to support medium layer which can form tow groups of wave-shaped yarns; wave peak and wave trough of the yarns are symmetric to each other and gradually staggered in horizontal direction. With high intensity in structure, good elasticity and structure uniformity, the invention can greatly improve the performance of capturing and storing dust, paint mist and oil mist.

Background technology

At present the fluffy felt air filtration scavenging material of being made by glass fibers is arranged also in the air filtration scavenging material, be used in the various dedusting filters.The fluffy felt air filtration scavenging material that existing glass fibers is made mainly is the glass fibre manufacturing of selecting different-diameter, felt silk irregular structure, and intensity and elasticity are bad, easy deformation, thickness attenuation in the use, dirt and filter capacity are held in influence greatly.

Summary of the invention

The purpose of this invention is to provide a kind of process for manufacturing puffy felt filtering material of glass fibre,, improve the structural stability of material and the appearance dirt filter effect of material, prolong life cycle to improve the structure structure of material.

The present invention uses the glass fiber wire-drawing machine that is made of glass furnace 1, glass fiber winding up roller 2, glue-spraying spout device 3, glass furnace 1 is installed on the coaster and is moved back and forth by program control frequency modulation motor drive level, be arranged on glass winding up roller top, at glass take up roll 2 sidepieces glue-spraying spout device 3 is set, glue-spraying spout device 3 is fixedlyed connected drive and is together moved with the glass furnace coaster.

Technical process:

A, adhesive preparation

101 glue with 25% solid content: water=30: 30-35, mix,

480 glue with 45% solid content: water=20: 25-30, mix,

With above-mentioned glue mixing and stirring, get adhesive;

B, wire drawing, glass furnace moves horizontally reciprocating motion under program control frequency modulation motor drives, twine by the glass fiber winding up roller wire drawing of rotating, simultaneously the glue-spraying spout device moves with glass furnace the glue mist is evenly sprayed on the glass fibre on the glass fiber winding up roller, glass furnace moves horizontally reciprocating motion under program control frequency modulation motor drives, and divides three phases to carry out;

Phase I, do at the uniform velocity moving back and forth, to form the following top layer of prismatic grid;

Second stage is done the reciprocating motion under the variable motion under the programme-control of setting, to form the central structure layer;

Phase III, do at the uniform velocity moving back and forth, to form the upper epidermis of prismatic grid;

The glass fibre thickness that twines on the glass fiber winding up roller reaches regulation and requires the back to shut down;

C, drawing-off, the glass fibre level cut-out vertically of twining on the glass fiber winding up roller is taken off, the fiberglass spinning cake that takes off is twisted on the axostylus axostyle, be placed on the drawing-off operation chopping board, open chain-plate type tunnel dryer, adjust the spacing that transmits carrier bar up and down of determining the tunnel dryer, fiberglass spinning cake on the tractive axostylus axostyle, drafted glass fiber extends fluffy naturally, bring in the tunnel dryer in the carrier bar of transmission up and down of feeding tunnel dryer, carry out hot-air seasoning typing 10-15 minute at 200-220 ℃, adhesive is fully solidified;

D, edging are sheared, rolling, packing.

The puffy felt filtering material of glass fibre that the inventive method is produced lower surface has thereon formed the top layer of prismatic grid, makes the puffy felt filtering material of glass fibre surfacing, and effective bonding overfill protection intermediate layer.The intermediate layer is done variable motion and is formed two groups of crests in front and back, cross section and symmetrical waveform silk a, a ' of trough under programme-control, thereafter symmetrical relative anterior waveform silk a, a ' of waveform silk b, b ' of two groups of crests and trough is the structure that level gradually interlaces, its structural strength height, good springiness, structural homogeneity is good, can improve the ability of seizure, storage dust, coating cloud, mist of oil greatly.

The specific embodiment

Technical process:

A, adhesive preparation:

101 glue with 25% solid content: water=30: 35, mix,

480 glue with 45% solid content: water=20: 25, mix,

With above-mentioned glue mixing and stirring, get adhesive;

B, wire drawing, glass furnace moves horizontally reciprocating motion under program control frequency modulation motor drives, twine by the glass fiber winding up roller wire drawing of rotating, simultaneously the glue-spraying spout device moves with glass furnace the glue mist is evenly sprayed on the glass fibre on the glass fiber winding up roller, glass furnace moves horizontally reciprocating motion under program control frequency modulation motor drives, and divides three phases to carry out;

Phase I, do at the uniform velocity moving back and forth, with the following top layer of formation prismatic water chestnut grid,

Second stage; With parking → acceleration → at the uniform velocity → quicken, move reciprocatingly under the circulation speed change, form the intermediate layer,
