Brighten mode in view of glaze for glazed tile, can by improve base substrate whiteness and raising cover-coat enamel whiteness reach similar
Effect, brightens mode around these three in experimentation and does a lot of work.
The serial example 1 of contrast: under the experiment condition of fixing step 2,3,4,5,6,7,8,9,10,11,12,13, only to step
Base substrate whiteness in rapid 1 is adjusted, and draws following table:
| Base substrate finished product whiteness | Formulation cost |
| 19-22 degree | 140-180 yuan/ton |
| 30-35 degree | 280-300 yuan/ton |
| 35-40 degree | 320-380 yuan/ton |
| 40-45 degree | 420-480 yuan/ton |
| 45-50 degree | 520-550 yuan/ton |
| 80 degree | Do not reach |
Base substrate is the basis of product, and its deformation has a direct impact to follow-up finished product glacing flatness and ripple glaze, by adopting
Selected raw material can improve finished product whiteness to a certain extent, but raw material is required too high.Also indivedual enterprises are had to be to reach in industry
To preferable base substrate whiteness, to be realized by slow burning (reducing more than half yield), thus can relax to base substrate composition
Require, the problems such as without excessively considering the deformation producing due to due to base substrate composition, a large amount of blank raw materials using high whiteness,
But because yield is too low, cost input is too big, also do not reach preferable whiteness simultaneously.Adjust the mode of whiteness using body recipe
Sexual valence is poor.
The serial example 2 of contrast: under the experiment condition of fixing step 1,2,3,5,6,7,8,9,10,11,12,13, only to step
Cover-coat enamel formula in rapid 4 is adjusted, simultaneously remaining component in fixing step 4, only the Zirconium orthosilicate. to impact whiteness most critical
Number be adjusted, draw following table:
| Zirconium orthosilicate. number in cover-coat enamel | Finished product whiteness | Cost | Finished product deforms (mm) |
| 10 | 42 | 0.6 yuan/square metre | Positive and negative 0.1 |
| 20 | 51 | 1.2 yuan/square metre | Positive 0.2 |
| 30 | 56 | 1.8 yuan/square metre | Positive 0.4 |
| 40 | 60 | 2.4 yuan/square metre | Positive 0.55 |
| 60 | 65 | 3.6 yuan/square metre | Positive more than 0.8 |
Because the coefficient of expansion of Zirconium orthosilicate. is less, if excessive add the deformation that can have a strong impact on product in cover-coat enamel so that producing
Product increasingly encircle with the increase adding Zirconium orthosilicate. amount, product.Simultaneously in cover-coat enamel after addition is a certain amount of, the impact to whiteness is got over
Come weaker, and the glaze volume of cover-coat enamel is relatively thick, so this scheme is also with high costs in the case of not reaching preferable whiteness,
But comparatively brightened using cover-coat enamel plus Zirconium orthosilicate. and either will be better than for the lifting of whiteness still becomes present aspect
Increase the input of base substrate whiteness and the effect of generation.
The serial example 3 of contrast: under the experiment condition of fixing step 1,2,3,4,6,7,8,9,10,11,12,13, only to step
Rapid 5 brighten glaze is adjusted, and draws following table:
By the research of three of the above mode, we can draw, brightens fancy glaze layer come improving product by silk screen printing
The technical scheme of whiteness, to consider from the whitening effect that can reach, production stability, product quality and integrated cost hence it is evident that
Better than the technical scheme lifting whiteness in terms of base substrate and cover-coat enamel.Preferable whiteness can be reached moreover it is possible to ensure the deformation of product
Deng in product in, external quality, and Optimum cost.This also exactly the present invention program advantage be located, by change tradition
Improve base substrate whiteness using drenching glaze mode, glaze layer is thicker and is difficult to adjust, the scheme that the present invention provides, there is provided a kind of suitable
Silk screen printing brighten glaze, it is used for ceramic tile production, can be reached different white by way of printing the different numbers of plies
Degree effect, makes process window more wide in range, is issued to best effect in the minimum situation of cost.
Increasing pink blossom glaze in step 7, using silk-screen printing technique, prints the set floral pattern consistent with ink-jetting pattern texture
(depending on meshcount is according to the required depth heightening the color and clear patterns degree, mesh number scope in 80-250 mesh, in this product
Use 160 mesh effect nets.Bigger using meshcount, pattern definition is higher, but the amplitude that can heighten the color is less；
And use silk screen mesh number less, then the definition of pattern and fine and smooth degree are lower, but the effect that heightens the color can be higher) so that
The color that InkJet printing processes do not reach can be compensated by increasing powder craft, thus reaching more abundant, face true to nature
Color effect.In product development and production process, can according to product need adjust silk-screen patterns and colorant proportioning, thus reaching
To the various patterns wanted and color.In this example embodiments, it is as follows that increasing pink blossom glaze presses mass fraction: high boron is calcareous transparent
