Abstract
The invention discloses a method for processing light weight mineral wool boards, which comprises the following steps: 1, premixing perlite, granulated wool, a sizing agent and water in a material mixing tank, making the mixed liquor generate shearing force in the material mixing tank in the mixing process, and making the perlite fully dispersed in the mixed liquor through the shearing force; and 2, adding the mixed liquor after mixing into a granulated wool processing work procedure in a process of producing the mineral wool boards in proper addition proportion. The method premixes perlite particles and granulated wool pulp, stirs the mixed liquor of the perlite particles and the granulated wool pulp in a shearing mode in the premixing process to evenly mix the perlite particles and the granulated wool pulp, and then adds the evenly mixed pulp into the granulated wool processing work procedure in the process of producing the pure mineral wool boards so as to realize adding the perlite particles into the mineral wool boards.
Description
Technical field
The present invention relates to a kind of processing method of light mineral wool slab.
Background technology
Mineral wool board is a kind of novel construction material, because of it has sound absorption, excellent characteristic such as heat insulation, fire-resistant is widely used on the ceiling of building.The mineral wool board that adopts substantially all is made up of pure mineral wool at present, and is therefore relative still heavier on weight.In order to obtain the mineral wool board of lightweight, need in mineral wool board, add some auxiliary materials.Though the perlitic trial of interpolation is arranged, in pure mineral wool board production system, directly add particles of perlite, all have no idea to realize particles of perlite is evenly mixed with the mineral wool slip through trial many times.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method of light mineral wool slab, can at an easy rate particles of perlite be added in the mineral wool slip, and reach and the mixed uniformly effect of mineral wool slip.
The processing method of a kind of light mineral wool slab of the present invention comprises the steps:
Step 1: in a mixing tank, perlite, granulated wool, sizing agent and water are carried out premix earlier, make mixed liquor in mixing tank, produce shearing force during batch mixing, perlite is well dispersed in the mixed liquor by shearing force;
Step 2: will mix the back mixed liquor according to suitable adding proportion and join in the granulated wool manufacturing procedure of mineral wool board production process.
Preferably, join successively in the mixing tank according to water 10～30%, perlite 30～70%, sizing agent 1～5% and granulated wool 20～40%, wherein percentage is weight percentage.
Preferably, the particle diameter of particles of perlite is less than 2mm.
Preferably, described perlite is the open cell type perlite.
The present invention passes through particles of perlite and granulated wool slip premix, the mixed liquor of particles of perlite and granulated wool slip is stirred with cut mode, thereby particles of perlite can evenly be mixed with the granulated wool slip, and then the mixed slurry that mixes is joined in the granulated wool manufacturing procedure of pure mineral wool board production process, just realized in mineral wool board, adding particles of perlite.
Description of drawings
Fig. 1 is the rotation batch mixing mechanism that premix adopted;
Fig. 2 be among Fig. 1 A-A to view.
The specific embodiment
The concrete operating procedure of the present invention is:
At first, as shown in Figure 1, in a mixing tank 3, will join successively and carry out premix in the mixing tank 3 earlier according to water 10～30%, perlite 30～70%, sizing agent 1～5% and granulated wool 20～40%, make mixed liquor in mixing tank 3, produce shearing force during batch mixing, perlite is well dispersed in the mixed liquor by shearing force.
The generation of this shearing force can be passed through as Fig. 1, rotation batch mixing mechanism shown in 2 realizes, specifically: this rotation batch mixing mechanism comprises drive motors 1, belt 2, rotating shaft 7, mixing tank 3 and stirring vane 4, stirring vane 4 is arranged on the rotating shaft 3 and passes through rotating shaft 7 in 3 li rotations of mixing tank jar, rotating shaft 3 drives belt 2 rotations by drive motors 1 and rotates, stirring vane 4 tops are provided with shear plate 5, offer some holes 6 of going up lower edge shear plate 5 up/down perforations on the shear plate 5, shear plate 5 is apart from the suitable spacing in mixing tank 3 tops, distribute preferably at 10～25mm, and along shear plate 3 radial radiation shapes.Wherein, stirring vane 4 can be directly tabular, also can be propeller-like.
When drive motors 1 drove rotating shaft 7 rotations, stirring vane 4 drove granulated wool slip and the particles of perlite rotation in the mixing tank 3.Offer porosely 6 on the shear plate 5, the slip band particles of perlite and is just passed through from hole 6, and flows along the direction of arrow shown in Fig. 1.In addition, because shear plate 5 has suitable spacing apart from mixing tank 3 tops, so mixed slurry will be subjected to along the shearing force of shear plate 5 circumferential direction, thereby forming between the shear zone between shear plate 5 and mixing tank 3 tops.Make particles of perlite to be distributed to well in the granulated wool slip by shearing force.In addition,,, and constantly from hole 6, flow through, therefore can access mixed effect very fully along helical form direction of arrow rotation among Fig. 1 because mixed slurry forms circinate flowing under the drive of stirring vane 4.
Secondly, the mixed liquor that obtains by above-mentioned steps is added to according to suitable adding proportion in the granulated wool manufacturing procedure of mineral wool board production process, so just can realize particles of perlite is added in the mineral wool.
The particle diameter of the particles of perlite that adopts is preferably less than 2mm, and perlitic type is the open cell type perlite preferably, can be blended in the granulated wool more fully like this.
Claims (4)
1. the processing method of a light mineral wool slab is characterized in that, comprises the steps:
