Abstract
High temperature resistant folding glass fibre filter net cloth is to belong to technical field of textile industry.
The technical problem that this invention solves is that fiber glass filtering net cloth is the high temperature resistant foldability that has again.Its adopts fiberglass gridding plain (21S/8 thigh, 6 strands) gained after pyroreaction behind the impregnation of organic silicon modified phenolic resin.Its main feature is high temperature resistant 1100 ℃ (5 minutes), and ablation resistance is good, has good rigidity and intensity, and does not foldingly rupture, and has solved glass fibre high temperature filtration net disadvantage frangibility, can make the filter of different shape with purposes.
The filter of the different shape of making of this filter cloth is widely used in aluminium, copper alloy and casting pig, the filtration of the iron of wriggling, iron casting and middle-size and small-size steel-casting, and the filtration of chemical industry corrosive liquid and environmental protection are with the chimney screen pack etc.
Description
This invention belongs to technical field of textile industry.
Glass fibre is high temperature resistant to be the highest fiber in the present textile fabric, and it is a wire drawing weaving gained in high temperature platinum, rhodium alloy pot.The field that can replace its fabric filtration cloth not use with glass fiber filter cloth.It has corrosion-resistant, high temperature resistant, characteristics such as intensity is high, good rigidity.But glass fibre has a fatal shortcoming, folding will the fracture, because these characteristics, thus now can only the high temperature resistant screen pack of production sheet, character is very crisp, bag filter can only be done the cost height with no bagging (being hollow pocket type cloth).And the filter that this seamless pocket type is produced can only anti-300～400 ℃ temperature, uses and is subjected to certain restriction.
The filter cloth that the present invention produces is to adopt glass fibre plain weave grid cloth (21S/6 thigh, 8 strands) gained after impregnation is handled, it has overcome the brashness of glass fibre, and the filter net cloth of producing is promptly high temperature resistant, can make the filter of different shape again according to purposes.As Fig. 1, filter, the filter bag that Fig. 2, aluminium alloy castings are used (tubulose), Fig. 3, triangle filter, these filters all are to adopt the glass fibre plain to make, and cost reduces greatly.
Show according to lot of research in recent years, from ablation resistance, the ablation resistance of phenolic resins＞organic siliconresin＞epoxy resin＞mylar, phenolic resins is best, at short notice can anti-2500 ℃ high temperature, and phenolic fiberglass reinforced plastics is instantaneous can anti-5500 ℃ or higher temperature.
Though phenolic resins has better comprehensive performance, phenolic aldehyde curing is closed, and benzene ring structure is tight.Though making it heat resistance raises, thereupon be to make resin fragility bigger, intensity is lower, again because the cohesive force between phenolic resins and the glass fibre is strong inadequately, so can not directly apply in the fiberglass gridding cloth, I introduce other group to phenolic resins for this reason.
Having added dibutyl ester in this prescription makes it that certain toughness be arranged as increasing tougheness.But owing to add dibutyl ester, the heat-resisting quantity of this glue decreases.In order to solve this, introduce ethyl orthosilicate again to improve its heat resistance to contradiction.This mainly is owing to behind the form cubic network, have the cause of the silicon oxygen bond that is similar to silicate sturcture in the structure.The bond energy (242.8KJ/ mole) of this carbon one carbon bond of the bond energy of silicon oxygen bond (372.6KJ/ mole) is much bigger, and therefore destroying silicon one oxygen key just needs higher energy.Promptly improve its heat resistance, had certain toughness again.
The objective of the invention is to make promptly high temperature resistant, and folding glass fiber filter cloth, thus may make the refractory glass fibre filter of different shape according to user's needs, change the fiber glass filtering net single problem of kind for a long time.
The method of producing this filter cloth is as follows:
1, joins glue
A, prescription
Thermosetting phenolic resin 2,124 20～25 grams
Mahogany acid 3 grams
Dibutyl ester 3 grams
Ethyl orthosilicate 2 grams
Ethanol 60 grams
Toluene 9 grams
B, teos solution
In plug mouthful tight there-necked flask, inject 9 gram ethanol, inject 2 gram ethyl orthosilicates rapidly, add 9 gram toluene at last.With the bottleneck jam-pack, vibrate a little, be made into the teos solution of 10% concentration.
C, be that basic component adds dibutyl ester, mahogany acid, ethanol (51 gram), the back that stirs and adds teos solution with phenolic resins, stir the impregnation glue of filter net cloth.
2, mould on
To go up the molding machine temperature and be controlled between 150 ℃～170 ℃, on to mould the time of staying be 60～120 seconds, glass fabric behind impregnation on the last molding machine through the baking oven reaction, but high temperature resistant folding endurance filter cloth.
The filter cloth that the method is made is compared it and is had not frangibility, Nai Fangwen 1100 ℃ (5 minutes) with present filter cloth, ablation resistance is good, and good Rigidity and strength is arranged. Solved the disadvantage of the high temperature resistant screen pack easy fracture of glass fibre, thereby the glass-fiber-fabric that can use continuous weaving is made the filter of various shapes, increased the scope of application of glass fibre filter net.
Claims (1)
- Advantages such as fiber glass filtering net has the intensity height, and is high temperature resistant, corrosion-resistant, but a fatal shortcoming is arranged is fragile material for it, therefore can not the same screen pack of making different shape with other cloth.Can only make filter at present, filter bag can only be made with seamless pocket type weaving, this filter bag can only be used between 300～400 ℃, and cost is very high, can not make the high-temperature resistant filter of pocket type and other shape with the glass fibre plain, the filter net cloth of making after the plain that the present invention adopts 21S/6 thigh, 21S/8 thigh ORGANDY to be made into is handled through impregnation has following feature:1, it is simultaneously corrosion-resistant again that filter cloth of the present invention has foldability, high temperature resistant 1100 ℃, 5 minutes, characteristics such as intensity height.2, this filter cloth can be sewn into the filter of different shape with purposes.3, adopt dibutyl ester, ethyl orthosilicate, phenol-formaldehyde resin modified binding agent as filter cloth.
