State 14-20 parts that nano zine oxide accounts for the lead-free gluzed overall component.
Further say, its step of preparation process is：
Step 1: dispensing：The dosage of oxide raw material is calculated by the chemical composition of offer, various raw materials is weighed and mixes
Uniformly；
Step 2: fusing and clarification：The raw material that step 1 is well mixed is put into tank furnace fusing, fusion temperature 1450-
1490 DEG C, clarifying temp is 1490-1510 DEG C, and the total duration of fusing and clarification is 13-17h, obtains glass metal；
Step 3: cooling：By the glass metal quenching melted to room temperature；Or the glass metal melted can be cooled to
1140-1190℃；
Step 4: shaping：By the glass metal of quenching to the room temperature shaping of dewaxing casting or hot melt shaping；Or can be according to setting
Shape is counted, the glass metal for being cooled to 1140-1190 DEG C is manually shaped；
Step 5: annealing：Shaped article is sent into annealing kiln annealing, annealing temperature is 460-510 DEG C, and insulation 3-4 is small
Shi Hou, it is slowly cooled to room temperature.
Further say, the lead-free gluzed density is 2.47-2.50g/cm3；It is swollen in 20-300 DEG C of temperature range
Swollen coefficient is 97-108 × 10-7/℃；Using viscosity as 106.7Thermometer during Pas, softening point are 525-532 DEG C；Annealing temperature
For 465-515 DEG C.
Further say, the fining agent is to contain CeO2Fining agent.
Further say, in addition to decolorising agent, the decolorising agent are the decolorising agent containing CoO.
Further say, the fusion temperature is 1455-1460 DEG C, and clarifying temp is 1495-1500 DEG C.
Further say, it is described lead-free gluzed also to include fluorescent whitening agent.
Further say, the annealing temperature is 465-600 DEG C.
The beneficial effects of the invention are as follows：The present invention at least has advantages below：
First, the basic ingredient of coloured glaze of the present invention is not leaded, harmless to environmental and human health impacts, and service life is grown, system
Cause low；
2nd, the coloured glaze quality manufactured by manufacturing process of the present invention is high, applied widely；
