Description
Technical field
The present invention relates to ceramic making field, more particularly, it relates to a kind of Multi-edge tile forming mould and by this mould
Have the ceramic tile and preparation method being pressed into.
Background technology
Preparing ceramic clinker is a kind of glass, forms through high temperature melting quenching, has the speciality such as insolubility, stability, through grinding
Impose on various vessel after mill, after firing, become the nature of glass of a thin layer, make to take on an entirely new look in pottery perception and use impression, be deeply subject to
Consumers welcomed.
More left than producing the common big 25-35mm of polished bricks product mold because producing the ceramic die design adding frit
The right side, such molding blank just has enough areas, adds granule frit, but still big not because of base substrate area when actual production,
And cause and melt to fall to regret to trickle above transmission club at granule frit in kiln high temperature sintering process, and it is easy to make
Club is become to fracture, the nominal price cost depletions of club.
If strengthened again by die size, rear working procedure processing difficulty, processing cost can be caused again to increase and waste of raw materials.
Have a strong impact on the production cost of finished bricks.
Additionally, in ceramic tile production process, through groping discovery, mould is arranged one while strengthening die size
The big hypotenuse suitably lengthened, guarantee semi-finished product also have 3-8mm through postorder after processing, and 5 DEG C of hypotenuses, such mould can
To prevent finished bricks from will not damage the corner of finished bricks in packaging i.e. handling process.But increase the big hypotenuse length of mould, meeting
Make adobe four weekly assembly form large area vacant state, there will be depending condition burning till period base substrate surrounding through kiln high temperature,
Have a strong impact on the degree of deformation of adobe, cause finished bricks to demote.
