Abstract
The invention belongs to the technical field of ceramic forming, and particularly relates to forming process for ceramic blanks for bathrooms. The forming process comprises steps that 1, forming materials are prepared according to proportion and mixed uniformly, 2, forming mud of a blank is refined and uniformly mixed, and moisture content of the mud is controlled below 30%, 3, forming mud in corresponding weight is taken according to the weight of the formed blank, 4, the forming mud is placed in a forming mold, and the mold is squeezed so that the blank is formed, and 5, by the aid of the forming mold, air is blown into a combined part of the forming mold and the blank, so that the blank is separated from the forming mold and is produced. The vertical compression forming process for ceramic blanks for bathroom is fast in forming speed, high in manufacturing efficiency, low in mold cost and small in occupied area, and the blank is compact sufficiently.
Description
Technical field
The invention belongs to the forming process of ceramics technical field, be specifically related to a kind of moulding process of bathroom ceramic form.
Background technology
The production process of bathroom pottery generally comprises following step, at first is the preparation slurry, uses the slurry preparing blank then, afterwards blank is carried out glazing, accomplishes production through sintering step at last.
Existing bathroom ceramic form adopts traditional slip-casting shaping process to make; Choose drain casting technology and solid casting technology according to the shape of bathroom ceramic form: promptly; Little opening blank for common is difficult to remove inner core, adopts drain casting technology to make moulding; For the blank of big opening or the little opening blank that can splice, take out inner core easily, adopt solid casting technology.
For the blank of big opening, like water tank, tank lid, squatting pan, hand washing sink etc., though can make through solid casting technology, it still exists following problem in the actual application:
1, the molding time of solid casting technology is longer, needs usually more than 4 hours, just can the demoulding;
2, the blank that solid casting technology obtains, density is even inadequately, the common good position of mould water absorbing properties, blank denser, and the imperfect position of water absorbing properties, blank is closely knit inadequately;
3, in the solid casting technology, thus may be owing to existing bubble to cause forming in the blank air blister defect in the slurries, packing is good inadequately;
4, need drying just can reuse after the mould demoulding, cause the make efficiency of blank low;
5, the solid casting moulding process because shaping efficiency is low, for large-scale production, needs to make a large amount of moulds usually, and this has not only increased production cost but also has taken a large amount of areas.
Summary of the invention
The technical problem that the present invention will solve provides the bathroom ceramic form moulding process that a kind of shaping speed is fast, make efficiency is high, die cost is low, area occupied is little and blank is enough closely knit.
In order to solve the problems of the technologies described above, the present invention provides a kind of vertical compression moulding process of bathroom ceramic form, includes following steps:
1) moulding material is disposed by proportioning, and mix;
2) the molding mass mud of refining blank mixes it, and control material mud water content is no more than 30%;
3), get the molding mass mud of corresponding weight according to the weight of moulded blank;
4) molding mass mud is placed in the mould, extrusion die makes its moulding;
5) through mould, blast air,, obtain blank so that blank separates with mould to mould and blank binding site.
As preferred version,, limit step 2 in order to guarantee the intensity of blank after the moulding) in, the water content of control material mud is 18%～23%.
As preferred version; Be convenient to separate in order to make mould with blank; Part that said mould contacts with blank adopts the K gypsum of absorbent ventilate to process, and the K gypsum can absorb the moisture on blank surface, reduces the caking property of itself and mould; Because the K gypsum can see through compressed air, be convenient to separating of blank and mould in addition.
As preferred version, in order to prevent to exist in the blank defective of pore, the material mud of preparation blank is 2) in carried out the vacuum degassing bubble and handled.
Adopt the vertical compression moulding process of the bathroom ceramic form of technique scheme to have following advantage: 1, owing to adopted the technology with the moulding of the direct pressing material mud of mould, than traditional solid casting moulding process, its shaping speed is fast; 2, because material mud has passed through the vacuum refining process between moulding, its density is even, does not contain bubble, and therefore the blank after the vertical compression moulding is more closely knit than the base substrate of traditional solid casting moulding; 3, because blank is to lean on the vertical compression moulding, the water content of blank own is little, and needs mould to absorb a large amount of water in the slip unlike traditional handicraft, so the vertical compression forming mould can use continuously, so the efficient of preparing blank is high; 4 since the vertical compression moulding to the demand of mould much smaller than traditional solid casting technology; Therefore the input cost of mould is little; The area that takies when using mould also reduces greatly, and 5, owing to adopted air to alleviate the cohesive force between blank and mould when moulding adobe blocks; Can prevent the blank distortion, improve the efficient of moulding adobe blocks.
The specific embodiment
Embodiment 1
The present invention provides a kind of vertical compression moulding process of bathroom ceramic form, includes following steps:
1) moulding material is disposed by proportioning, and mix;
2) the molding mass mud of refining blank mixes it, and control is expected the mud water content about 18%, and material mud is carried out application of vacuum, removes the bubble that possibly contain in the material mud;
3), get the molding mass mud of corresponding weight according to the weight of moulded blank;
4) molding mass mud is placed in the mould, extrusion die makes its moulding;
5) part that contacts with blank of mould adopts the K gypsum of absorbent ventilate to process, and blasts air through mould to mould and blank binding site, so that blank separates with mould, obtains blank.
Embodiment 2
The present invention provides a kind of vertical compression moulding process of bathroom ceramic form, and its step and embodiment 1 are basic identical, and distinctive points is 2) in control material mud water content about 30%.
Embodiment 3
The present invention provides a kind of vertical compression moulding process of bathroom ceramic form, and its step and embodiment 1 are basic identical, and distinctive points is 2) in control material mud water content about 23%.
Above-described only is preferred implementation of the present invention; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from process thought of the present invention, can also make some distortion and improvement; These also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
