Description
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 very great shortcoming, that is exactly that the strength of materials is inadequate, particularly when being used as the base material of three-dimensional green wall, easily strips off event.
Improving one of settling mode of the stripping strength of agricultural rock wool is utilize stronger tackiness agent, but there will be environmental issue, and effect is also unsatisfactory.Another kind of mode makes each layer of rock wool produce pleating in the fabrication process.Utility model patent CN201220326750 discloses a kind of rock wool shaping system with function of crumpling, but its not open details how realizing crumpling.Chinese patent application 201010512495.8 discloses a kind of rock wool pleating machine, realize the pleating of rock wool by the velocity contrast organizing lower compression roller more, the product that this pleating methods obtains makes each rock wool layer produce fold, this fold produces component in a thickness direction, be conducive to the stripping strength improving rock wool product, but according to principle of products, can not connect between the layers, therefore for the limited efficiency that stripping strength improves, the actual product commercially sold also demonstrate that this point.Another shortcoming is, the gauffer risen and fallen in rock wool product actually increases rock wool layer stretching allowance in a longitudinal direction, and impart the elasticity of the more longitudinal direction of this rock wool product and thickness direction, architectural, this character does not often cater to the need.
Prior art pleating only has rock wool layer moving towards in the horizontal direction and changes, and does not have direct interaction, thus can not form three-dimensional bridging arrangement between different rock wool layer.Fig. 4 illustrates the section of the prior art rock wool product with rock wool layer fold, and as seen from Figure 4, although fluctuating gauffer appears in rock wool layer, the relation between each layer still keeps complete, and interlayer relation is not strong.Fig. 5 is rock wool product of the present invention, and as can be seen from Figure 5, the connection relation between each layer greatly strengthens, and is even difficult to tell complete rock wool layer, and between each rock wool layer, staggered occlusion, makes whole product become an entirety.
Rock wool product utilization of the present invention adopts the pressure cotton machine manufacture with the fancy pressure roller of outstanding pressure roller sheet and pressure roller groove to form.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, is respectively first group of pressure roller, 1, second group of pressure roller 2 and the 3rd group of pressure roller 3.Should be appreciated that, although what illustrate for exemplary purposes in this figure is three groups of pressure rollers, the pressure roller group number of reality can change, such as four groups or more groups, such as, also has other pressure roller group after the 3rd group of pressure roller shown in this Fig. 1.The upper lower compression roller group of each group has independently driving mechanism 4, so that manufacturing speed is poor between each group pressure roller and between upper lower compression roller.Or velocity contrast also can use common or that part is common driving mechanism, adopts different gear ratio to reach by different transmission rigs.Top also has upper and lower roller space setting device 5.
As seen in Figure 3, this fancy pressure roller has outstanding pressure roller sheet 7 and pressure roller groove 8 therebetween to an embodiment of fancy pressure roller.Pressure roller sheet trend shown in this Fig. 3 is identical with rock wool traffic direction, but should be appreciated that, actual pressure roller sheet trend can also be angled with rock wool traffic direction, is even interconnected to form overall helicitic texture.
Width between the pressure roller sheet of above-mentioned fancy pressure roller and pressure roller groove is than generally between 1:1-1.5.Two adjacent fancy pressure rollers can be engaged mutually, as shown in Figure 2.In other cases, two fancy pressure rollers are not engaged, such as, when screw-type pressure roller, or fancy pressure roller and ordinary light face pressure roller mutual alternate intervals when.
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, to receive loose rock wool layer.First group of pressure roller does not generally adopt fancy pressure roller, because the effect of fancy pressure roller and surperficial rock wool layer can not be delivered to inside by loose rock wool layer, can not realize object of the present invention.But also can adopt fancy pressure roller in several pressure rollers rear of first group of pressure roller.
First group and all there is velocity contrast between second group and the upper lower compression roller of the 3rd group, and the positive-negative relationship of velocity contrast is mutually contrary.Such as barrel velocity difference v about first group
1for when positive, namely on first group barrel velocity faster than lower compression roller, then about second group barrel velocity difference v
2be negative, namely barrel velocity is slower than lower compression roller on second group, and lower compression roller difference v on the 3rd group
3for just.When velocity contrast, original different rock wool layers entering pressure cotton machine start to move with different speed, when entering first group of pressure roller effect under, 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 adopts 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, therefore the velocity contrast between the different piece causing same rock wool layer, in this layer, velocity contrast inwardly transmits step by step, particularly under the existence of fold, causes overall in layer destruction, and overlap between form layers, form three-dimensional connection.Interlayer connection makes whole rock wool product formation entirety, strengthens integral rigidity, makes the performance enhancement of product.
Summary of the invention
The object of the invention is to a kind of openly method manufacturing agricultural rock wool, by adopting new material mixture ratio, fibroblast is effective, Fiber Distribution is even, is conducive to having connection at the cotton interlayer of difference, thus forms the structure of overlap joint mutually, 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 characterized in that, said method comprising the steps of: 1) prepare burden: the raw material co-grinding of following weight part is formed into stove raw material: basalt 70-80, Wingdale 5-8, slag 3-5, coke 20-30 and auxiliary material 3-5 part; 2) melting: the raw material prepared is melt into magma in cupola furnace at the temperature of 1470-1570 DEG C; 3) fibroblast: the magma whizzer of fusing is got rid of silk, sprays binding agent and hydrophilizing agent simultaneously; 4) collection is cotton: the fiber collecting thrown away is on the collection web of cotton collecting machine; 5) paving is cotton: utilize pendulum bob machine to form multilayer and to loosen rock wool layer; 6) pressure is cotton: by described loose rock wool layer through the compacting of three-dimensional pressure cotton machine; 7) solidify: the consolidation rock wool body pressed through three-dimensional pressure cotton machine is sent into curing oven solidification, forms the three-dimension integrally structure with interlayer bridging arrangement; 8) repair: be trimmed to applicable size shape by specification.
