A kind of manufacture method of agricultural rock wool
Technical field
The present invention relates to rock wool field of novel, relate in particular to the manufacture method of a kind of agricultural rock wool.
Background technology
Agricultural rock wool is a kind of current generally acknowledged ideal a kind of soilless culture base material.But existing agricultural rock wool material has a shortcoming the most great, that is, the strength of materials is inadequate, particularly when as the base material of three-dimensional green wall, it is susceptible to the event of stripping off.
One of settling mode of peel strength improving agricultural rock wool is to utilize higher adhesive, but there will be environmental issue, and effect is the most unsatisfactory.Another way is that each layer making rock wool in the fabrication process produces pleating.Utility model patent CN201220326750 discloses a kind of rock wool shaping system with function of crumpling, but it does not discloses how the details that realizes crumpling.Chinese patent application 201010512495.8 discloses a kind of rock wool pleating machine, the pleating of rock wool is realized by the speed difference of the upper lower compression roller of many groups, the product that this pleating methods is obtained makes each rock wool layer produce fold, this fold produces component in a thickness direction, be conducive to improving the peel strength of rock wool product, but according to principle of products, connection can not be set up between the layers, therefore the effect improved for peel strength is limited, and the actual product commercially sold also demonstrate that this point.Another is disadvantageously, the gauffer risen and fallen in rock wool product actually increases rock wool layer stretching allowance in a longitudinal direction, imparts this rock wool product more longitudinally and the elasticity of thickness direction, and architectural, this character is often and undesirable.
Summary of the invention
It is an object of the invention to disclose a kind of method manufacturing agricultural rock wool, by using new material mixture ratio, fibroblast is effective, fiber is evenly distributed, and is conducive to having connection at different cotton interlayers, thus forms the structure of mutually overlap joint, obtain real three dimensional structure, to improve the performance of rock wool product.
Specifically, the technical solution used in the present invention is as follows:
The manufacture method of a kind of agricultural rock wool, it is characterised in that said method comprising the steps of: 1) dispensing: the raw material co-grinding of following weight portion is formed into stove raw material: basalt 70-80, limestone 5-8, slag 3-5, coke 20-30 and adjuvant 3-5 part;2) melted: the raw material prepared is melt in furnace cupola at a temperature of 1470-1570 DEG C magma;3) fibroblast: the magma centrifuge of fusing is got rid of silk, sprays binding agent and hydrophilizing agent simultaneously;4) collection cotton: the fiber thrown away is collected on the collection web of cotton collecting machine;5) paving cotton: utilize pendulum bob machine to form multilamellar and loosen rock wool layer;6) pressure cotton: by described loose rock wool layer through three-dimensional pressure cotton machine compacting;7) solidification: the consolidation rock wool body pressed through three-dimensional pressure cotton machine is sent into curing oven solidification, forms the three-dimensional overall structure with interlayer bridging arrangement;8) finishing: be trimmed to be suitable for size shape by specification.

Detailed description of the invention
The more detailed description present invention is carried out below in conjunction with accompanying drawing.
The advantage of the agricultural rock wool of the present invention is, by using new proportioning, utilizes the formula that fibroblast is effective, obtain the distribution of uniform fiber, connect by being internally formed interlayer rock wool, form staggered three dimensional structure so that the overall performance of rock wool product is strengthened.
Prior art pleating only has rock wool layer moving towards in the horizontal direction and changes, and does not has direct interaction, thus can not form three-dimensional bridging arrangement between different rock wool layers.Fig. 4 illustrates the section of the prior art rock wool product with rock wool layer fold, as seen from Figure 4, although fluctuating gauffer occurs in rock wool layer, but the relation between each layer remains in that completely interlayer relation is the strongest.Fig. 5 is the rock wool product of the present invention, from figure 5 it can be seen that the connection relation between each layer greatly enhances, is even difficult to tell complete rock wool layer, staggered occlusion between each rock wool layer so that whole product becomes an entirety.
The rock wool product utilization of the present invention uses the pressure cotton machine of the fancy pressure roller with prominent pressure roller sheet and pressure roller groove to be fabricated by.Fig. 1 illustrates the structural representation of this kind of pressure cotton machine.The pressure cotton machine of the employing fancy pressure roller shown in Fig. 1 has three groups of pressure rollers, 1, second group of pressure roller 2 of respectively first group pressure roller and the 3rd group of pressure roller 3.Although it will be appreciated that be illustrated that three groups of pressure rollers in this figure for exemplary purposes, but the pressure roller group number of reality can change, such as four groups or more groups, such as, after the 3rd shown in this Fig. 1 group pressure roller, also has other pressure roller group.The upper lower compression roller group of each group has independent drive mechanism 4, in order between each group of pressure roller and between upper lower compression roller, manufacturing speed is poor.Or speed difference can also use common or that part is common driver, uses different gear ratios to reach by different drive mechanisms.Top also has upper and lower roller space adjusting means 5.
As seen in Figure 3, this fancy pressure roller has prominent pressure roller sheet 7 and pressure roller groove 8 therebetween to one embodiment of fancy pressure roller.Pressure roller sheet trend shown in this Fig. 3 is identical with rock wool traffic direction, it is to be appreciated that the pressure roller sheet trend of reality can also be at an angle of with rock wool traffic direction, is even interconnected to form the helicitic texture of entirety.
Width ratio between pressure roller sheet and the pressure roller groove of above-mentioned fancy pressure roller is typically between 1:1-1.5.Two adjacent fancy pressure rollers can be mutually twisted, as shown in Figure 2.In other cases, two fancy pressure rollers are the most engaged, such as in the case of screw-type pressure roller, or in the case of fancy pressure roller and common bright finish pressure roller alternate interval.
During compacting rock wool, the rock wool layer completed enters from first group of pressure roller.The upper pressure roller group upwards opened with certain angle of first group of pressure roller, in order to receive loose rock wool layer.First group of pressure roller does not the most use fancy pressure roller, because the effect of fancy pressure roller Yu surface rock wool layer can not be delivered to inside by loose rock wool layer, it is impossible to realize the purpose of the present invention.But fancy pressure roller can also be used in several pressure rollers rear of first group of pressure roller.
All there is between first group and second group and the upper lower compression roller of the 3rd group speed difference, and the positive-negative relationship of speed difference is the most contrary.Such as barrel velocity difference v about first group1In the case of just, on i.e. first group, barrel velocity is faster than lower compression roller, then about second group barrel velocity difference v2Being negative, on i.e. second group, barrel velocity is slower than lower compression roller difference v on lower compression roller, and the 3rd group3For just.In the case of speed difference, original different rock wool layers entering pressure cotton machine start to move at different rates, when entering under the effect of first group of pressure roller, it is faster than bottom rock wool layer that top rock wool layer moves, but when moving to second group of pressure roller, bottom rock wool layer is faster than top rock wool layer again, to the 3rd group of pressure roller, top rock wool layer is faster than bottom rock wool layer again, so causes each rock wool layer in distortion, is formed pleating.
Second group to the 3rd group pressure roller of pressure cotton machine uses fancy pressure roller, as seen in Figure 1.When rock wool layer contacts with fancy pressure roller, pressure roller sheet contacts with rock wool layer, and pressure roller groove can not, thus result in the speed difference between the different piece of same rock wool layer, in this layer, speed difference transmits the most step by step, particularly in the presence of fold, and overall destruction in causing layer, and form interlayer overlap joint, form three-dimensional connection.Interlayer connection makes one entirety of whole rock wool product formation, strengthens integral rigidity so that the performance enhancement of product.
Embodiment 1: by weight 75 parts of basalt, limestone 6 parts, 5 parts of slag, 25 parts of coke, 3 parts of fluorite, 1 part of co-grinding of kieselguhr are added furnace cupola, furnace temperature 1470-1570 DEG C is spent, it is filled with liquid oxygen, melted, magma passes through four roller centrifuge fibroblasts, and phenolic resin adhesive and hydrophilizing agent preparation solution are sprayed in exit, after collection cotton, pendulum bob machine paving cotton, enter pressure cotton machine, after solidification, make three dimensional structure rock wool.
Above in conjunction with accompanying drawing, embodiments of the present invention are described in detail, but the invention is not restricted to above-mentioned embodiment, in the ken that art those of ordinary skill is possessed, it is also possible to make a variety of changes on the premise of without departing from present inventive concept.
