Description of drawings
Fig. 1 is the manufacture method schema of the present invention's light weight aggregate in embodiment.
Embodiment
For fully understanding purpose of the present invention, feature and effect, now by following specific embodiment, and cooperate appended graphicly, the present invention is described in detail, illustrate as afterwards:
At first see also Fig. 1, the manufacture method schema of light weight aggregate of the present invention.The manufacture method of light weight aggregate of the present invention comprises the following step: prepare masterbatch S101, add water stirring S102, granulation S103, health S104 and dry screening S105, then will narrate this five step respectively.
At first prepare the step S101 of masterbatch: prepare the masterbatch of this light weight aggregate, this masterbatch can comprise in an embodiment:
Weight percent is 20% to 40% inorganic clay;
Weight percent is 50% to 60% ore powder material;
Weight percent is 10% to 20% agglutinate; And
Weight percent is 2% to 10% additive.
Wherein, this inorganic clay is general clay; The powder material that this ore powder material is general ore; This agglutinate is selected from the arbitrary of following material or its combination: cement, lime powder, terra alba and magnesia powder; This additive is selected from the arbitrary of following material or its combination: methylcellulose gum, polyvinyl alcohol, water glass, water-resisting agent, acrylic resin, polyvinyl acetate resin, and Cornstarch, talcum powder and zeolite powder.
The function of aforementioned inorganic clay is to help granulation process, allows this masterbatch flexible and plasticity-when moisture state.The function of ore powder material is promptly filled material, and the ratio that accounts for is higher, and the powder waste that a purpose of the present invention promptly produces in solving various ore process of manufacture allows waste be able to the resource recycling.The function of agglutinate makes the glued hardened forming of this masterbatch, to density, the main influence of hardness generation of bullet body.The function of additive has the mediation function, in order to be in harmonious proportion agglutinate, inorganic clay, and the ore powder material between bonded viscosity, slickness, water tolerance, whiteness etc.
In this masterbatch of another embodiment of the present invention, this inorganic clay more can be selected from the arbitrary of following material or its combination: attapulgite clay, wilkinite or montmorillonite soil.
In another embodiment, this ore powder material can be selected from the arbitrary of following material or its combination: perlite powder, vermiculite power or marble flour.
In addition, In yet another embodiment, this inorganic clay is selected from the arbitrary of following material or its combination: attapulgite clay, wilkinite or montmorillonite soil, simultaneously, this ore powder material is selected from the arbitrary of following material or its combination: perlite powder, vermiculite power or marble flour.
Then add the step S102 that water stirs: add water and stir and make this masterbatch be moistening shape, this masterbatch adds promptly can begin to carry out " hydration reaction " behind the water and hardened forming slowly promptly can carry out next procedure at incomplete presclerotic moisture state: granulation.In a preferred embodiment, the water yield that adds this masterbatch is 30% to 50% of this masterbatch volume, the loose measure when this masterbatch volume refers to the masterbatch drying.
Then carry out the step S103 of granulation: masterbatch that will this moistening shape is sent into tablets press to be shaped to particle; this granulation step can adopt tablets presss such as general food tablets press, pill tablets press or feed tablets press; to produce all size of light weight aggregate of the present invention, the particle grain size size can adjust in actual demand.
Then carry out the step S104 of health: the particle of granulating and forming is carried out health, and to increase hardness and intensity, in a preferred embodiment, the carrying out of health can adopt normal temperature cold junction method or steam to steam connection.Wherein, the granulated pellet of first one-step forming is added water cast health with normal temperature or with warm water soaking health seven to ten days, this was " health of normal temperature cold junction method "; Perhaps the granulated pellet of first one-step forming is sent into normal temperature steam curing stove or the health of high pressure steam health stove, this is " health of steamed connection ".
Dry the step S105 of screening at last: carry out particulate oven dry and sifting sort, so that the uniform specification of light weight aggregate can be packed and shipment afterwards.Wherein, also can comprise a painted step at step S105, as: soak painted or spray colouration, so that the finished product of light weight aggregate can give different mark looks according to actual demand, as: different-grain diameter gives distinct colors and defines with clear identification.
Almost being the original inorganic material in the Nature entirely in the mother metal composition of light weight aggregate of the present invention, is inorganic mineral products, processed goods even waste material, and for example cement, lime, gypsum itself all are the inorganic mineral processed goods, is used in material of construction in a large number.Attapulgite clay, wilkinite, zeolite powder, montmorillonite soil etc. itself are exactly a kind of clay, can bring plant vegetables, mud is bathed even make feed.Marble flour, perlite powder, vermiculite power or ore powder then are respectively dust waste that marble, perlite, vermiculite deposit or other stone material ore deposit produce and reclaim via precipitron in the course of processing, these materials can be recycled in the present invention.
The hardness and the weight of light weight aggregate is controlled in light weight aggregate of the present invention can see through this agglutinate (weight percent is 10% to 20%) and ore powder material (weight percent is 50% to 60%) when reality is implemented ratio adjustment, for example: when the agglutinate ratio increases, when ore powder material ratio reduces, the hardness of light weight aggregate and weight will increase, otherwise are exactly the reduction of hardness and weight.
For instance, under framework of the present invention, realize that general light weight aggregate can adopt following prescription, weight percent all with masterbatch as benchmark:
1. inorganic clay: attapulgite clay powder 10%, wilkinite 10% add up to 20%.
2. ore powder material: perlite powder 45%, vermiculite power 5%, marble flour 5% add up to 55%.
3. agglutinate: cement 7%, lime powder 5%, terra alba 5% add up to 17%.
4. additive: methylcellulose gum 2%, water glass 3%, water-resisting agent 3% add up to 8%.
Inorganic clay of the present invention, ore powder material, agglutinate, and the specification demand of the visual light weight aggregate of additive or the difference that easily obtains material along with the grown place come masterbatch is done choosing and allocating in various degree.For instance: the consumption of terra alba can improve in the manufacturers that obtains terra alba easily, reduces or gets rid of lime, magnesian interpolation fully; Rich area of producing the magnesium oxide ore deposit, or the manufacturers that obtains this kind material easily will reduce or get rid of the consumption of terra alba, lime, and other is as the same.
The present invention discloses with preferred embodiment hereinbefore, so has the knack of this operator and it should be understood that this embodiment only is used to describe the present invention, does not limit the scope of the invention and should not be read as.It should be noted,, all should be made as and be covered by in the category of the present invention such as with the variation and the displacement of this embodiment equivalence.Therefore, protection scope of the present invention when with claim the person of being defined be as the criterion.
