Description
Technical field
The present invention relates to type material production field, relate in particular to a kind of production has the rock wool product of three-dimensional connecting structure method in inside.
Background technology
Existing rock wool manufacturing process relates to the fiber magma of ore charging melting being blown silk formation, elaborated by pendulum and form loose multilayer rock wool layer, this multilayer rock wool through compacting through the upper lower compression roller of overvoltage cotton machine, enters curing oven solidification, forms asbestos product.The common rock wool of making through this technique only has two-dimentional stacked in a thickness direction, and not crosslinked occlusion, therefore stripping strength is very low, when being used as material of construction, also need if desired to utilize the workpiece such as rivet to fix further in a thickness direction, thus affect construction process and material lifetime, and thisly fixed also impact is caused on the practical effect of rock wool to fastening, such as have impact on its isolation performance.
In the prior art, be utilize stronger tackiness agent to one of settling mode of this problem, 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.
The inventive method utilizes the pressure cotton machine adopting and have the fancy pressure roller of outstanding pressure roller sheet and pressure roller groove.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 multilayer the completed rock wool layer that loosens 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 three-dimensional structure rock wool, the rock wool of being produced by this kind of manufacture method has connection at the cotton interlayer of difference, thus form the structure of overlap joint mutually, obtain real three-dimensional structure, to improve the performance of rock wool product.
