Check
2. production technology is resolved:
(1) treating of wood and wood wool preparation:
The necessary peeling of the log that uses, because the sugar content height of bark, and fibre composition is low, intensity is low.Use log to cut out saw and be divided into juggle long about 0.2m by sawing machine.Should adopt the artificial and automatic means that combine that detect will be attached to the foreign material removal that harm such as the mud on the timber, hard thing, iron nail, metal object are produced when drawing materials, purpose is in order to protect the safety of saw blade and miscellaneous equipment.The timber of different shape and length is sawn into the former material of specification length, for follow-up plane silk segment is prepared.To saw good short wood by automatic conveying device then and deliver to wood wool making machine, and dig the wood wool of specific length and width, the width of wood wool is 2mm in the present embodiment.
(2) the mineralising impregnation process of wood wool:
In order to overcome harmful components in the timber, should adopt mineralizer (being chemical admixture) wood wool to be carried out impregnation process, the about 1min～2min of dip time to the anticoagulation of cement.Mineralizer not only has short effect of coagulating high-early (strength) cement, and can also improve the durability of goods.
Water resistance and anti-moth performance.Mineralizer can be divided into three types by its effect to cement and wood materials: first kind Admixture is the illeffects that reduces the timber water-soluble substances, and has stable insoluble chemical compound with its generation; The second class Admixture is the sclerosis of quickening cement; The 3rd class Admixture is to form membranoid substance on the surface of timber, and sealing is hindered the hazardous substances of hydrated cementitious and separated out.
The concentration of mineral agent is looked the quality of timber, and the humidity benchmark is relevant with cement, and the concentration of mineralizer (concentration is measured with hydrometer) is generally between 1.02～1.08.
Because the solubility sugar in the timber is in continuous variation, so the addition of chemical assistant should be done corresponding adjustment thereupon.Ying Jing is everlasting and detects the hydration time of mixture in the laboratory.
(3) wood wool mixes and mats formation:
The mixing uniformity of cement, wood wool and water is most important, otherwise can influence the intensity of sheet material, cause not firm formation layering of overlap joint and cavity between wood wool simultaneously, combined amount is carried out in the cylinder machine of continous way, can not use the shaft type mixer, otherwise wood wool can be destroyed, interrupts, the cement, wood wool, the water that enter mixer must carry out measuring fixed amount as requested.
The ratio of wood wool and cement is chosen in 1:1.2-1.3 in the present embodiment.The ratio of water and cement is that water/binder ratio is 0.7, and the not enough aquation intensity that can influence cement of the addition of water is inconvenient to stir simultaneously, and excess moisture can make cement suspend and starch the surface of course plate, also can cause the cement surface short texture.
The moulding of mating formation is the core that cement wood wool composite mineral wool board is produced, and this relates to the even distribution of wood wool in the sheet material; Density tolerance, sheet material are separated and whether are formed the strength problem that runs through cavity and sheet material.
The water ratio uniformity that stirs the back mixture is the important indicator that stirs the result.The main cause that causes the moisture content fluctuation is a wood wool measurement of water-content coefficient error.The moisture content error of mixture should be in certain limit.If the moisture content error is too big, then when weighing, slab increases the amount of dummy sketch and the inhomogeneities of plate.
Because the built on stilts effect of wood wool, the compression ratio of slab therefore must be through precompressed up to 10:1.The cement wood wool compound that the stirs bottom surface cement wood wool of on conveyer belt, mating formation earlier, pass through continuous rolling again, by preformer the slab compression ratio is reduced to 3:1 or littler, and then after putting into intermediate layer material mineral wool board (whole mineral wool board of slitting formula), repave dress end face cement wood wool.Carry out precompressed once more, make cement, wood wool, mineral wool in the slab reach preliminary bond strength.
(4) mineral wool preparation:
The mineral wool board that buying is returned carries out overturning 90 behind the slitting
0, sliver 5 is vertically arranged (parallel with the length direction of plate), and sliver must make its size keep regular with special-purpose unit slitting, can guarantee the thickness and the plate surface evenness of composite plate.Be critical between bar and the bar by seamless, to guarantee the intensity of composite plate, the width of sliver is identical with the thickness of layer of mineral wool.
(5) compacting of product and insulation are handled:
Slab after precompressed is finished is sent in the press of the pressurize of heating of continous way, between the two ends of press, has steel plate to pass through the slab heating, makes slab finish final set as early as possible and reaches certain intensity.Slab suppresses out the laggard incubator of going into from press, and the temperature of incubator can be adjusted, and slab has only by maintenance facilitates hardening of cement.Curing condition comprises curing temperature, time and air humidity, and they have bigger influence to the performance and the production cycle of sheet material, under the room temperature natural curing cycle long, if curing temperature is too high, particularly 100
0Can cause dehydration rapid more than the C, cement does not reach predetermined degree of hydration, influences the intensity of cement wood wool composite mineral wool board and produces distortion, and suitable holding temperature is 60
0C～90
0C.
(6) the facing deep processing cuts shaping:
After slab is handled through insulation, further strengthened the intensity of composite mineral wool board, making whole slab reach the saw limit handles, make it to become the finished size that needs, blank flat is earlier through deburring, with high speed mould saw slab is sawn into the length 1.2m that needs then, slab is sawn into the production board of 0.6m width, at last with production board stacking and packing.
The cement wood wool composite mineral wool panel products physical and mechanical property index of present embodiment is asked for an interview Fig. 3.
Fig. 4 is seen in present embodiment product cement wood wool composite mineral wool board and prior art benzene plate systematic comparison contrast.
