Abstract
The invention discloses a production process for disassembly forming of a ceramic pedestal pan, which comprises the following process steps of: mould design; slip casting; die sinking and drying; billet adhesion; and glazing and sintering. The product qualification rate of the ceramic pedestal pan produced by the process can reach over 85 percent; and the pollution discharge and water conservation of the product meet and even exceed the standard of national water-saving products.
Description
Technical field
The present invention relates to ceramic field, specifically a kind of production technique of disassembly forming of ceramic pedestal pan.
Background technology
Ceramic pedestal pan is generally all formed by water tank, toilet body with the pedestal that toilet body wraps up, and toilet body comprises bedpan and the pipeline that joins with bedpan.Whether ceramic pedestal pan can connect together with other parts according to water tank, is divided into body-lined type and split type.In traditional mode of production, no matter body-lined type or split type, it all is the overall time moulding that the moulding of sitting wc pan is produced, and promptly is that toilet body and pedestal are connected together, disposable injection forming in same mould, and this production technique is easy to generate following problem:
1, pedestal and the moulding of toilet body once time synchronization; The sun-dried mud brick body dry with burn till that unbalanced in the contraction (the pedestal wall is thicker and present flat state; The toilet body wall approaches and presents case of bending at bath pipeline position; Shrinking percentage of the two and shrinkage direction are inconsistent), cause that easily the shrinkability of pedestal and each tie point of toilet body ftractures, perhaps the contraction owing to pedestal affects toilet body to cause the pipeline modification;
2, pedestal and toilet body are in same mould, and pipeline is hidden in the pedestal inner face, and die design is difficult, and cause Product Variant and other quality problems during die sinking easily;
3, in the die design, pipeline is if improve, and it is unobstructed to make it the draining blowdown, then need under the condition of global formation permission, can implement, and comprises the suction slurry that guarantees mould in the pipeline moulding process and shrinks evenly;
4, in the overall time moulding, the concentration of mud is consistent, is difficult to simultaneous adaptation pedestal plane and the pipe bending demands of different to slip fluidity;
5, in the overall time moulding, because moulding is identical with time of drying, the water ratio of pedestal and pipeline is inconsistent, and formed product and sintering qualified rate are difficult to stable, can't further improve.
Summary of the invention
For overcoming above-mentioned deficiency; The invention provides a kind of production technique of disassembly forming of ceramic pedestal pan; Make pedestal and toilet body separate moulding production, it is bonding then the sun-dried mud brick spare of producing through moulding separately to be carried out mud, through glaze spraying with burn till; Pedestal and toilet body are fused, form a complete sitting wc pan.
The production technique of disassembly forming of ceramic pedestal pan of the present invention comprises following process step:
1, die design:, and on toilet body, reserve the position that is connected with pedestal with the pedestal and the toilet body difference designing mould of sitting wc pan;
2, injection forming: allocate ceramic mud respectively by conventional ceramic production technology, the used mud of pedestal is 72～76 degree Beaume, and the used mud of toilet body is 64～65 degree Beaume, respectively mud is injected mould molding then;
3, die sinking is dry: pedestal is in injection forming die sinking seasoning 2～4 hours after 4～5 hours; The corresponding toilet body injection forming time should be grown 2～4 hours than pedestal; The seasoning time also needs to grow 2～4 hours than pedestal after the die sinking; Make the water ratio of pedestal and toilet body soil property base substrate reach 13～18% synchronously, help the two bonding back dry shrinkage synchronously;
4, base substrate is bonding: adopt pedestal grouting mud to be coated in the connecting portion of pedestal and toilet body, then the two correspondence is fixed, wipe the unnecessary mud of interface;
5, glazing is burnt till: the base substrate seasoning after bonding is after 5～8 hours, goods are carried out glazing and burns till by the ceramic pedestal pan ordinary method, processes product.
Technology of the present invention, when the production conventional one-piece toilet stool, its water tank and design of toilet body integration mold and injection forming.
The present invention adopts disassembly forming production, the pipeline of toilet body can be designed by the direction of effective blowdown and water saving, and because the toilet body mould is independent, do not involve mutually with the pedestal mould, and Mold Making is easy, can consider the restriction of pedestal profile.The pedestal of moulding and toilet body can not pin down in dry shrinkage each other respectively, and can be directed against pedestal and toilet body, adopt the mud production of different concns respectively, can satisfy the slip fluidity requirement of sintering process, improve the quality of products.
Ceramic pedestal pan with explained hereafter of the present invention; Product percent of pass can reach (traditional integral moulding product qualification rate has only 75～80%) more than 85%, and the blowdown of product meets or exceeds the requirement (water consumption is minimum can to reach 3 liters) of national saving product of water with economizing on water.

The toilet body sectional view that Fig. 1 produces for the present invention.
The pedestal sectional view that Fig. 2 produces for the present invention.
The sitting wc pan sectional view that Fig. 3 produces for the present invention.
Embodiment
Embodiment: shown in Fig. 1～3, the present invention is with the pedestal 2 and toilet body 1 difference designing mould of sitting wc pan, and the position 3 that reservation is connected with pedestal 2 on toilet body 1;
Allocate ceramic mud respectively by conventional ceramic production technology, pedestal 2 used mud are 74 degree Beaume, and toilet body 1 used mud is 65 degree Beaume, respectively mud is injected mould molding then;
Adopt pedestal 2 grouting mud to be coated in the connecting portion of pedestal 2 and toilet body 1, then the two correspondence is fixed, wipe the unnecessary mud of interface;
Base substrate seasoning after bonding is after 6 hours, goods are carried out glazing and burns till by the ceramic pedestal pan ordinary method, processes split type sitting wc pan.
Comparative Examples 1: different with embodiment is, pedestal and toilet body adopt same mould, disposal molding, and used mud is 70 degree Beaume, and the injection forming time is 5 hours, and seasoning is 4 hours after the die sinking.The product of being produced modification occurs at the pipeline place of toilet body, has 30% goods fine crack to occur at the connecting portion of pedestal and toilet body.
Comparative Examples 2: different with embodiment is to separate the pedestal of moulding and the mud that toilet body all adopts 68 degree Beaume.The pedestal wall density of the product of being produced is not good enough, and there is scarce mud phenomenon (concentration of hydraulic mixture is difficult to pass through smoothly the knee too greatly) the pipeline part of toilet body.
Comparative Examples 3: different with embodiment is that pedestal and toilet body be injection forming and die sinking simultaneously simultaneously.Because the rate of drying of pedestal and toilet body is inconsistent; When the toilet body water ratio reaches 15%; The water ratio of pedestal is 20～22%; Do not meet in the technique for sticking the essentially identical requirement of bond water ratio, tiny crack appears in product pedestal and the toilet body connecting portion produced, need repair.
