The present invention uses wet processing, length fibre to arrange in pairs or groups by a certain percentage, uses novel binders, and the product of production is endured with all one's will Spending moderate, fiber is uniformly dispersed, and thickness is stable, and hole is little, the advantage having papery and glass fiber reticular cloth concurrently, is preferable filleting band Update new product.
The product of the present invention is plasterboard filleting glass fibre mat.
Compared with prior art, the invention has the beneficial effects as follows:
(1) owing to using glass fibre as raw material so that this caulking material water-tolerant, indeformable after the moisture absorption, do not send out Mould；
(2) two kinds of different-diameters and the glass fibre of length are used so that this caulking material fiber is uniformly dispersed, and thickness is steady Fixed, hole is reasonable；
(3) novel binders is used so that this caulking material stiffness is moderate, and structural stability is good, and good appearance is follow-up Coat easy to process；
(4) this caulking material distribution of pores is reasonable, with finishing binding agent and gypsum slurry friendly interface, mat after coating It is firmly combined with plasterboard, surfacing.
(5) this caulking material hole is little, the advantage having papery and glass fiber reticular cloth concurrently, with finishing binding agent and calcium plaster Material friendly interface, after coating, mat is firmly combined with plasterboard, surfacing, is preferable filleting band update new product.
(6) different colors can be processed into as required, meet and use requirement.
Detailed description of the invention
Prepare the technique of filleting glass fibre mat include the suction of slurry preparation, dehydration forming, impregnation, baking and curing, Batch the several workshop sections of packaging.Below in conjunction with embodiment, the present invention is described further.
Embodiment 1
The preparation method of plasterboard filleting glass fibre mat is as follows:
1, slurry preparation:
First, agitator tank, slurry tank add the pure water of certain volume, for ensureing that glass chopped silk realizes monofilament Dispersion, in addition it is also necessary to add the auxiliary agents such as a certain amount of thickening agent, dispersant, defoamer in pure water being made into viscosity is the white of 7.0CP Water.
After plain boiled water has been prepared, respectively by diameter 13 microns, glass fibre that length is 18 millimeters and diameter 18 microns, length Two kinds of glass fibre of 36 millimeters add feed bin, and stir in belt conveyer scale weighing in proportion input plain boiled water, prepare slurry, In slurry, the concentration of glass chopped silk is about 0.14%.Wherein, the ratio of long fibre and chopped fiber is 1:1.
2, dehydration forming:
Slurry uniformly sends into flow box through homogenizer grout outlet, and is realized by stepped diffuser and orifice plate in flow box Laterally homogeneous cloth is starched, and then five drying zones through flow box carry out gravity dehydration, and the dehydration flow of each drying zone is by adjusting Whole dehydrated tube valve is controlled, and in this embodiment, five drying zone dehydrating amounts hourly are respectively as follows: 350m3, 300m3, 900m3, 600m3And 200m3。
Slurry through gravity dehydration removing major part plain boiled water, glass chopped silk be evenly distributed on guipure formed wet The molding guipure that felt, glass chopped silk and the plain boiled water that can not be removed are operated continuously is taken away, and suction is forced in Zai Jing tri-road Take out unnecessary plain boiled water.Both sides have air tube can control the width of wet felt, and the wet hair limit of excision enters white water chest recycling.
3, impregnation aspirates:
The wet felt of glass fibre after dehydration is delivered to impregnate on guipure by molding guipure, and binding agent is beaten to leaching through pump by work tank Overflow adhesive applicator above stain guipure, is immersed in wet felt from the binding agent supersaturation that adhesive applicator flows down, unnecessary binding agent Being pumped by twice suction box, separated tank comes back to after separating circulate in work tank.
Described binding agent is the mixed liquor of Lauxite, acrylate, coupling agent and mill base, the mass percent of four For 50:9:1:1.The concentration of the binding agent emulsion configured in wet felt dipping process is 20%.
4, dry:
The wet felt completing impregnation suction is transferred to curing oven guipure by impregnating guipure, is entered by hot air convection in curing oven Row is dried.Curing oven is by a preheating zone, and five baking and curing districts compositions, each curing area is by a circulating fan and natural Air burner, the temperature in each district can independently control, and the dampness in each district is concentrated by a Fans and discharged, and dries temperature and leads to Cross computer controlled automatic, the fan housing up and down of drying oven is uniformly offered a lot of aperture, it is ensured that hot blast blows to felt face equably On.
5, batch:
After going out curing oven, felt has been maxed out strength, arrives winding off spindle through " S " roller, rip cutting rotor, and " S " roller can make Batch and obtain bigger tension force, but tension force is unlikely and passes in curing oven.Otherwise, the lowest will be unable to of wet felt strength produces.Batch Use double air-expanding shaft, overcoat paper tube, outside paper tube, be wound around two-sided tape.Reach certain length, automatic change of lap, revolving knife Automatically fall off cut-out felt.Rip cutting blade can be installed on longitudinal knife rotor, cut into different width according to customer requirement.Finally take out Go out air-expanding shaft product is packed.
