Description
Technical field
The present invention relates to Ceramic Tiles manufacturing technology field, in particular to a kind of parent applied to entire body large size ceramic plate
The preparation method of water type dry mixing colorant.
Background technique
Currently, well known Ceramic Tiles entire body production technology is that wet type slurry or wet type are combined with dry type colour mixture, the two is right
Than under, wet processing is a whole set of system, including ball mill, spray tower, underground stock tank etc., and all devices after colorant are added
Will be contaminated, it will be cleaned when if desired making other different colours powders, artificial intensity is big, and the production cost is very high, pollution
Also very big, and a preparation amount is excessive, if scheduled production yield is inaccurate, for preparing has toner material needs to outwell or press storehouse more, causes
Waste.Dry process advantage is relatively obvious, and ball mill, spray tower need to only prepare single white material, wastes less, without cleaning,
Want how much to match how many.But because powder with the particle diameter of colorant differs too big, powder particles be big 100 times of pigment granules with
On, therefore dry process is wanted uniformly to mix extremely difficult, the product effect made generally can be more far short of what is expected than wet process.Dry method colour mixture
Though it is each has something to recommend him to match colors with wet process, from long-range energy conservation and environmental protection and from the point of view of each pottery enterprise's production practices these years and market in general trend,
Dry method colour mixture technique has become the first choice of entire body marble production, and entire body Ceramic Tiles easily go wrong mainly in process of production
Have following aspects, one side green body is to guarantee that the stabilization of texture need to utilize grid by powder because forming texture using powder vehicle cloth
Material is sent to mold cavity, will form grid print if some characteristics of powder are improper again, and serious product is burnt into kiln discharge
It can see afterwards, slight is polished rear obvious；On the other hand, since dry-mixed colorant is one layer of package in existing production powder
Expect on surface, exists suppressing and being easy to appear layering, color spot in dry method colour mixture production process, increase powder due to dry mixing process
Blanking caused by the arch bridge effect of conveying process is unsmooth and the defects of causing color difference etc., finally seriously affect the comprehensive visual of product
Effect, thus for specification entire body plate big for the ceramics that exploitation has more added value, key problem in technology core is entire body cloth
Material equipment, dry method additive colo(u)r system, and the technology of preparing of the especially dry-mixed colorant of production technology aspect.
Key technology main points one of of the dispersing agent as dry-mixed colorant, especially the attribute of dispersing agent directly determines dry-mixed color
The property of material affects the performance used in connection with of dry mixed powder indirectly.Since the marmorean production of entire body itself does not have standard, respectively
The machinery equipment of a producer is again inconsistent, and therefore, there are mainly two types of attributes, i.e. hydrophilic for the dry-mixed colorant product in existing market
Dry-mixed colorant and the dry-mixed colorant product of hydrophobic group.Currently, most of producer receives and uses the dry-mixed colorant of hydrophilic in market
Product, especially imported product mainly based on the dry-mixed colorant of hydrophilic, domestic manufacturer before this more producers using dredging
Water base dry-mixed colorant is done all one can to catch up in application technology in this respect in recent years, and there has also been very big breakthroughs, such as in recent years
There are some producers using gas-phase silicas products such as Degussa, the Cabots of import, domestic fumed silica is with import
Product differentiation is reducing, but in general, still has a certain difference in terms of the production application of hydrophilic dispersing agent technology.
In conclusion existing entire body production technology needs to optimize, high-quality lithotome effect is in particular produced
Entire body large size ceramic plate, in terms of the especially preparation of the dry-mixed colorant of production technology of cloth system, dry method colour mixture technology also
Need to pay more proprietary technology schemes for making great efforts to grope and improve a set of production domesticization.
