Abstract
The invention relates to a dry powder pressure moulding method of ceramic bottleneck, comprising the steps of preparing special bottleneck slurry by using china clay, clay, Kaolin clay, feldspar and kibushi-clay, and then adding water and sodium silicate and carrying out sufficient ball-milling to obtain slurry with relatively good flowability; adding a prepared methylcellulose solution into the slurry to enhance the strength of a pressure moulded blank, further obtaining dry powder particles by using an integrated device of spraying, drying and prilling; moulding the dry powder in mode of dry compression by using a high precision hard alloy ceramic bottleneck mould and dry powder hydraulic pressure moulding machine, thereby obtaining a dry blank semi-finished product; finally obtaining a bottleneck blank having a size precision no more than +/- 0.005mm uniformly by using an automatic processing device; the bottleneck quality is greatly superior to that of conventional products; the method in the invention has high automation, the problem of high consumption of time, labor and material is solved, especially, resource consumption is reduced; no plaster mould is used, so that no waste discharge is realized and the ceramic bottle can be used widely.
Description
Technical field
The present invention relates to the ceramic bottle processing technique field, relate in particular to a kind of ceramic wine bottle bottleneck full-automatic dry powder pressure forming method.
Background technology
Domestic ceramic bottle mouth mostly adopts the mode of injection forming or roll forming at present, and injection forming main production process step mainly comprises: prepare mud, mud is injected in plaster mold and carries out injection forming, adopt finally cutlery adjustment; As shown in Figure 1, step comprises in the roll forming technological process: prepare mud, and press filtration, pugging, inject pugging in the ceramic bottle mouth mould it carried out roll forming, adopts the cutter repaired biscuit of accurate dimension.
Injection forming and roll forming have three common ground: the one, adopt the high raw material of moisture content, after injection forming, moisture content is greater than 24%, the roll forming moisture content is 18～20%, because the high operating process of moisture content is exerted oneself, careless slightly just generation distortion, the distortion because of the super deviation of size and generation reaches 15% left and right qualitatively; Because bottleneck quality is one of most important factor in the ceramic bottle production process, and the bottleneck size precision very easily changes along with the size of pug moisture content, the moisture content size in production process be do not allow manageable; The 2nd, both technique all adopts plaster mold, Mold Making is for making by hand, when size poor consistency, each mould are used more than 20 times, specification is because of the working face wearing and tearing significant change of mould, the general impact of adopting the access times that reduce each mould to reduce this drawback; The 3rd, manually-operated, production efficiency is lower, and labour intensity is also large, these two kinds of forming methods per capita output per day 2000 left and right, scale error ± 0.5mm, be easy to produce metaboly, and bottleneck size is difficult to control and easily is out of shape, encapsulation filling to mechanization and brings very large difficulty.
There is defect in prior art, haves much room for improvement.

Wherein, the mold materials of described ceramic bottle mouth adopts the high accuracy carbide alloy.
Concrete, in technical solution of the present invention, the composition of raw materials that adopts mainly comprises:
China clay: be (H4Al2Si2O9) primary raw material of pottery, pure china clay is a kind of white or canescence, and the soft mineral of gloss as tiffany are arranged.The composition of pure china clay is: SiO2 46.51%, Al2O3 39.54%, H2O 13.95%, and fusibility is 1780, the total amount that is reflected in SiO2 content on chemical composition higher (general〉70%), Al2O3 content lower (approximately 16 ~ 24%), K2O and Na2O high (approximately 2 ~ 8%).The refractoriness of china clay is also low than kaolin.
Clay: the main body chemical composition of clay mineral is sieve and silica-sesquioxide and water, but it is characterized in that being combined with suitable quantity of water that furnishing softens and can have plasticity around the ooze that refers to, will can become the hard sintered body with certain humidity after the walk of Plastic Forming burning.Clay generally is fine dispersion particle, has simultaneously associativity; The main body when appearance of clay makes it become the ceramic body sintering, the main source of mullite crystal in the formation porcelain.
Kaolin, mainly by kaolinite bunch mineral (kaolinite, dickite, nacrite, galapectite etc.) such as the small sheet less than 2 microns, tubulose, lamination shapes, formed, desirable chemical formula is AL2O3-2SiO2-2H2O, its essential mineral composition is kaolinite and halloysite, except kaolinite bunch mineral, also have other mineral associations such as montmorillonite, illite, pyrophillite, quartz and feldspar.Contain a large amount of AL2O3, SiO2 and a small amount of Fe2O3, TiO2 and micro-K2O, Na2O, CaO and MgO etc. in kaolinic chemical composition.
Feldspar: have potassium, sodium, the calcium of so-called frame shape crystal structure, the aluminosilicate of barium, namely have [AlSi3O8]-or the manosil AS root of [AlSi3O8] 2-, wherein the ratio of (Al+Si) and O 1:2 always; The feldspar chemical analysis is the gypsum that natural product does not contain the crystallization water, main component is calcium sulfate (CaSO4), in addition, often assorted aluminium oxide (Al2O3), ferrous disulfide (FeS2), magnesia (MgO), the silica (SiO2) that trace is arranged, and strontium, barium etc.
Kieselguhr: be a kind of rich organic high plasticity sedimentary clay, the essential mineral composition is kaolinite, halloysite and a diaspore.Kieselguhr usually darkly, brown, blue, grey, brown isochrome, be the main bonding clay of ceramic industry, but it is dry and to burn till contraction larger, consumption is too much unsuitable, the present invention controls its content, and to account for percentage by weight be 5%.
Waterglass (flower bulb alkali): formal name used at school is sodium metasilicate, sodium potassium silicate, is colourless or slightly look, transparent or semitransparent thick liquid, can be water-soluble, and acid decomposition, its anhydride is unformed glassy mass, and is odorless tasteless, do not fire not quick-friedly, is that alkalescence is arranged.
Methylcellulose: this product is white or off-white color is fibrous or particulate powder; Odorless, tasteless.This product is swelled into the colloidal solution of clarification or little muddiness in water; Insoluble in absolute ethyl alcohol, chloroform or ethanol, its chemical composition is the methyl ether cellulose, pressing dry product calculates, contain methoxyl group and (OCH3) should be 27.0%-32.0%, the methocel solution that the present invention will modulate adds the intensity that can strengthen the pressure forming blank in mud, and wherein methocel solution concentration is 5～10%.
In the present invention, the Processes and apparatus of specifically not described etc. is all the conventional uses of the industry.
beneficial effect of the present invention is: after the present invention adopts technique scheme, due to configure dedicated bottleneck mud, and by the higher spraying of automation, dry, granulating integrated equipment, adopt state-of-the-art high accuracy sintered-carbide die, by obtaining a kind of dry body semi-finished product after pressure forming, obtain the dimensional accuracy unification through more than half or full-automatic process equipment to be no more than ± the bottleneck blank of 0.05mm, bottleneck quality obviously is better than traditional mode of production, the proportion of goods damageds＜1%, every secondary die life 1,000,000 times, per capita every day 6000 of output, every ten thousand production costs only have 45% of original production process, labour intensity obviously reduces, and new technology all adopts the meter key operation, automaticity improves, solve the present situation of the time-consuming expense material high flow rate of taking a lot of work, particularly reduced resource consumption, do not use plaster mold, realized simultaneously the no waste discharging, thereby ceramic bottle is widely used.
