Abstract

A handle joining technique for ceramics includes such technological steps as sticking the dried raw components with handle by a binding mud, washing in water, baking, enamelling and calcining. Said binding mud is prepared from raw porcelain powder, middle-pit powder, fine porcelain powder, enamel and sodium humate through proportional mixing, ageing, sieving to remove iron and ageing.

Description

Technique for dry linking ceramics

The present invention relates to a kind of ceramic making technology, be specifically related to a kind of stem grafting technology of pottery handle.

It generally all is to carry out on the basis of moist base substrate that the traditional pottery of China connects technology, it mainly is to carry out bondingly under each parts water ratio situation higher but unanimous on the whole by controlling, and causes and ftractures and come off thereby make ceramic can be owing to not shrinking inconsistent in dry and sintering process not produce big stress in the abutting edge.Therefore, such technology is brought significant limitation to the ceramic product especially decoration of Shi porcelain products, just can not carry out as look of all kinds limit decoration, make most of space of ceramic cup stay blank, be unfavorable for decorating between type supporting integrity at the middle part of ceramic cup.

The present invention's purpose aims to provide a kind of very big expansion ceramic decoration space, safeguard supporting decoration integrity between various types, make easy, easy to operate, the firm technique for dry linking ceramics of solid, smooth and beautiful appearance.

Technical solution of the present invention is: the binder clay various subassemblies that drying is good with special preparation make up bonding, carry out wash water, oven dry, glazing then, burn till, the binder clay of described special preparation is mixed according to the suitable proportioning weighing by base powder, middle hole powder, fine porcelain powder, stone glaze, add less water, stir evenly after old 1-2 days, add the Sodium salts humic acids of trace again, sieve then, deironing, last old 3-5 days, binder clay just prepared.

Its weight percent proportioning of the component of above-mentioned binder clay is: base powder 70-74%, middle hole powder 20-24%, fine porcelain powder 3-6%, stone glaze 1-3%, Sodium salts humic acids 0.4-0.5%.

Sieving in the above-mentioned binder clay compound method, deironing, old operation are described in detail as follows respectively:

Sieve: the sieve aperture of mud with proper viscosity by setting, remove the coarse grained a kind of method that wherein surpasses the setting aperture, be referred to as to sieve, generally adopt vibratory screening apparatus, its objective is and remove impurity and coarse particles.

Deironing: adopt tramp iron separator that the irony impurity in the pug is removed, generally adopt the filtering type wet separator, the product after the deironing can improve whiteness.

Old: pug sealed in the environment of suitable temperature and humidity place for some time, this process is old, its objective is that to make the pug component even, and plasticity improves, and the old time is generally and got final product in 3-5 days.

The testing data of binder clay is: fineness: 250 mesh screen residues＜0.6%, and moisture content 36%, the old time is more than 3 days.

Its Chemical Composition degree of binder clay main raw material is:

Base powder: SiO ₂: 68.93, Al ₂O ₃: 19.62, Fe ₂O ₃: 0.8, TiO ₂: 0.16, CaO:0.35, MgO:0.33, K ₂O:2.38, Na ₂O:0.61 burns and loses 6.61; Middle hole powder: SiO ₂: 14.4, Al ₂O ₃: 14.2, Fe ₂O ₃: 0.62, TiO ₂: 0.07, CaO:1.04, MgO:0.49, K ₂O:4.61, Na ₂O:0.14 burns and loses: 2.91; Stone glaze: SiO ₂: 62.5, Al ₂O ₃: 15.20, Fe ₂O ₃: 0.35, TiO ₂: 0.1, CaO:3.5, MgO:1.5, K ₂O:6.5, Na ₂O:1.5 burns and loses: 2.5: fine porcelain powder: SiO ₂: 69.95, Al ₂O ₃: 20.52, Fe ₂O ₃: 0.83, TiO ₂: 0.17, CaO:0.37, MgO:0.35, K ₂O:2.5, Na ₂O:0.65 burns and loses: do not have.

Technique for dry linking ceramics of the present invention with drying good can not be integrated the base substrate of cup class and cup, binder clay with special preparation sticks together, the employing of this technology makes that carrying out look of all kinds limit decoration at cup class middle part becomes possibility, make look of all kinds limit unblocked at cup class middle part, safeguarded the integrity of supporting decoration between various types, greatly widened the ceramic decoration space, the present invention simultaneously makes easily, prescription is simple, easy to operate, after bonding the burning till, firmly solid, smooth smooth attractive in appearance, avoided original tide to connect the shortcoming that technology is out of shape easily,, developed ceramic market improving the quality of products and class, play great pushing effect, especially opened up a brand-new road aspect the ceramic colored drawing.

As everyone knows, the base substrate of ceramic cup class is generally roll forming, the blank structure densification, cup is then generally using injection forming, structure is more loose, both shrink inevitable inconsistent in sintering process, and this just can only play shock absorption therein by binder clay preferably, and two parts are combined becomes an intact ceramic product well.Bonding process is: at first carry out following preparation work, to wet cup cutting, scrape smooth, wash clean with pocket knife, making up and down, interface keeps certain radian, oven dry, standby, be ready to two writing brushes, special small bamboo spike, one bowl of binder clay, a keg clear water, a wet sponge again, next earlier at base substrate appropriate location ratio once with the cup handle, on wet sponge, dip in a clear water then, get a little binder clay again, in clear water, soak, firmly evenly and rightly be connected on the correct position of cup; Then with writing brush with unnecessary binder clay outwash, press equably 2-3 time at interface with the small bamboo spike of cutting system specially, at last with band water writing brush with the joint wash clean, promptly finished the whole series and connect a technology.

Claims
