Abstract
The invention discloses production mud of high-regularity sanitary ceramics and a preparation method of the mud. The production mud comprises the following chemical compositions in percentage by weight: 61.33-61.97% of SiO2, 25.07-25.89% of Al2O3, 0.89-1.15% of Fe2O3, 0.3-0.7% of TiO2, 2.9-3.62% of CaO, 0.2-0.51% of MgO, 1.07-1.59% of K2O, 0.21 to 0.33% of Na2O, and 5.93-6.49% of Lg. Loss. According to the invention, raw materials are preferred, Zuoyun elutriated clay and ball clay which are small in deformation, small in water absorption and good in plasticity are used, and a large number of contrast tests are performed in the process of creative improvement, so that the ratio of raw materials is obtained. According to the invention, the content of aluminum in a formula is improved, and therefore, the mullite content after vitrification is greatly increased, and the high-temperature viscosity is increased, so that the bending deformation in the process of burning is reduced, and an obvious effect of reducing defects such as poor propelling, poor drill and mud skeins is achieved; and various problems that ordinary mud is easy to crack in the process of producing large-size and high-regularity products, and edges and surfaces of products are easy to deform, and the like are solved.
Description
Technical field
The present invention relates to the ceramic technology field, production mud of especially a kind of high regularity snitaryware and preparation method thereof.
Background technology
Snitaryware is the important articles for use closely bound up with people's daily life, along with socioeconomic fast development, the raising of living standard, sanitary and balneal room no longer have been traditional simple toilets, and leisure, pleasant mental and body become life fashion and pursuit.Sanitary and balneal room Art Design art up and personalized, manufacturing has proposed higher standard-required to sanitaryware, particularly the regularity of product is had higher requirement.
The porcelain sanitary china has determined the natural characteristics of its high deformation from the height liquid content, adopt the product of firing after the regular mud moulding in the snitaryware production, such as some large products and to product size and the demanding product of regularity, be difficult to reach standard-required, it is also higher that the size of ceramic is burnt till more greatly difficulty, except product is easy to crack, and the product surface distortion, edge deformation, the quality problems such as whole distortion are to cause the underproof one of the main reasons of product.After sanitary ceramic product generally passed through 1200-1250 ℃ of high-temperature calcination, water-intake rate was generally less than 0.5%, because the product glassy phase is more, can produce flexural deformation under action of gravity in calcination process, was difficult to reach the requirement of high regularity.
Summary of the invention

The present invention is made by the raw material of following weight percent: Zhanjiang A 9.1～11.3%, porcelain stone 4.5～6.8%, calcite 5.5～7.7% burns A 10.8～12.9%, prosperous credit mud 11.7～13.9%, kaolin 4.3～6.5%, ZhangZhou soil 6.2～8.3%, Zuoyun soil 8.3～10.6%, ball clay 9.1～11.3%, calcined kaolin 10.5～12.8%, quartzy 6.5～8.8%.
The weight percentage of the preferred raw material of the present invention is: Zhanjiang A 9.7%, and porcelain stone 5.5%, calcite 7.2 % burn A 11.8%, prosperous credit mud 13.6%, kaolin 5.3%, ZhangZhou soil 7.3%, Zuoyun soil 9.8%, ball clay 10.3%, calcined kaolin 11.7%, quartzy 7.8%.
Physical index after the present invention is old is: concentration 360～380g/200ml, cross 325 mesh sieve residue rates 6～10%, and V0=50～70 second/100ml, slurry thickness 7.0～8.0mm/hr is eaten in V30=110～130 second/100ml.
Burning till after the present invention is old can the shape index be: dry shrinkage 2.0～2.5%, and burn till and shrink 3.0～3.5%, entirely shrink 5.0～5.5%, flexural deformation＜7%, water-intake rate 8～10%.
Preparation method of the present invention is: behind porcelain stone, Zhanjiang A and calcite mixed grinding, add to burn then that A, prosperous credit mud, kaolin, ZhangZhou soil, Zuoyun are native, ball clay, calcined kaolin and quartzyly fully stir last old getting final product.
The fineness of the described grinding of preparation method of the present invention reached 325 mesh screen residues, 0.1～0.3wt% residue.
Preparation method of the present invention is at least 10 days the described old phase; Describedly in old process, sieve through 60 orders, 80 orders and 100 order vibratory screening apparatuss successively, and before sieving at every turn through the abundant deironing of magnetic separator.
The beneficial effect that adopts technique scheme to produce is: the problems such as the present invention is used for high regularity sanitary china and produces special-purpose mud, and is easy to crack when overcoming the product that regular mud is large in the production size, regularity is high, and product edge and surface are yielding.
The present invention adopts preferred to raw material, the use distortion is little, water-intake rate is little and plasticity is eluriated soil and ball clay in the Zuoyun preferably, has carried out a large amount of simultaneous tests in inventive improvements, thereby has drawn proportioning raw materials of the present invention.The present invention improves the aluminium content in the prescription, thereby significantly increases the content of mullite after the vitreous, increases high temperature viscosity, and the flexural deformation in the sintering process is reduced, to become, the reduction of the defectives such as the hole is bad, mud tuft has positive effect.
The present invention has improved the water-intake rate of finished product porcelain, when reducing the distortion of finished product porcelain, effectively impels high-temperature volatile gas to discharge smoothly, to reduce product pin hole, orange peel glaze, pinhole, the defectives such as sootiness.Because the raising of water-intake rate has not had pin hole, orange peel glaze, the restriction of the defectives such as pinhole is so can significantly increase the high-ductility raw material.
The present invention has improved the dry body strength of product plasticity and base substrate, and this brings a lot of benefits to production: the one, and the work in-process qualification rate is significantly improved; The 2nd, make the damaged obviously minimizing of work in-process; The 3rd, because the raising of blank strength has reduced coming off of the inner burr of base substrate, reduced one-tenth dirty, glaze is dirty and most kiln is dirty, has obviously improved goods manufacturing accuracy and qualification rate.
Add calcite and quartz in the raw material of the present invention, in the wet swelling that reduces base substrate, improved the coefficient of expansion of base substrate, make glaze be subjected to higher stress, thereby improved the freedom from cracking performance of snitaryware finished product, guarantee that it has sufficiently long work-ing life.Residue rate and the mud physicals stability that guarantees mud property of the present invention by controlling out mill mud prevents the cracking in the moulding process.
Along with the gradually increase of plasticity material, the shaping speed of mud can reduce gradually among the present invention, and reason is that the high-ductility material easily is polished in entering the mill process meticulous, causes in the mud fine particle proportion excessive.So eat slurry speed in preparation method of the present invention for the moulding that does not reduce mud, natural plasticity material and rough machined hard material are entered the mill grinding, washing plasticity material and finishing labor and materials powder later stage enter the pond and stir.
