Some embodiments and comparative example
Influence of the sintering temperature to properties of product, i.e. method and step be the same as Example 6 are determined, change the is the difference is that only
Three sections of sintering temperature, as shown in table 1：
Influence of the different sintering temperatures of table 1 to properties of product
| Comparative example 1 | Embodiment 7 | Embodiment 6 | Embodiment 8 | Embodiment 9 | Embodiment 10 | Comparative example 2 | |
| Sintering temperature (DEG C) | 850 | 950 | 1050 | 1100 | 1120 | 1200 | 1400 |
| Density | 1.55 | 1.69 | 1.51 | 1.48 | 1.43 | 1.41 | 2.67 |
| Water absorption rate | - | 13 | 17 | 18 | 24 | 27 | 0 |
| Aobvious porosity | - | 27 | 27 | 28 | 36 | 39 | 0 |
| The efficiency of purifying formaldehyde | - | 88 | 81 | 84 | 79 | 76 | 0 |
Conclusion：By upper table we have seen that, firing temperature is less than temperature range of the present invention, then occurs that low intensity is un-sintered easy
Fracture, fires the temperature of pottery clay plates when reaching more than 1200 degree, porosity is drastically reduced, and when reaching 1400 degree, pottery clay plates have been
Porcelain plate is burnt till, water absorption rate, aobvious porosity and purifying formaldehyde efficiency are zero.
Comparative example 3
A kind of diatom pottery clay plates, material composition be the same as Example 1, preparation method be the same as Example 1 the difference is that only：
Step 1) in diatom pottery clay plates only include diatom mineral matter, i.e.,：
1) sorting, 0 part of 35 parts of diatom mineral material and china clay material are mixed.
2) it is molded, by step 1) 300mm × 600mm × 18mm slab is made in the mixed material.
Sintering, by the diatom pottery clay plates Temperature fall after being calcined through 1200 degree of temperature Celsius to normal temperature；
The result finally given shows：Due to lacking china clay material, therefore, the result after firing still reverts to powder.
To so sintering process be caused to fail；
4) cut, because 3) step fails, therefore, this step can not start；
5) detect, because 3) step fails, therefore, this step can not start；
Comparative example 4
A kind of diatom pottery clay plates, material composition be the same as Example 6, preparation method be the same as Example 6 the difference is that only：Step
It is rapid 3) described in dry for one-part form dry, 110 DEG C of drying temperature, drying time is 12h；
The calcining is one-part form calcining, is 1050 DEG C of calcining 3h.
After testing, there is crackle in the outward appearance of diatom pottery clay plates made from the present embodiment, is defect ware.Mainly dry with forging
It is caused without slowly heating up during burning, it is therefore not necessary to determine performance indications.
Comparative example 5
A kind of pottery clay plates, method and step be the same as Example 6, the difference is that only：
The pottery clay plates, by weight meter consisting of：3 parts of 0 part of diatom mineral matter, 97 parts of clay and tourmaline.
As a result the pottery clay plates burnt out, shape is normal.But, water absorption rate reaches 2.4g/m less than 10%, density, is not inconsistent
Close the density requirements of diatom pottery clay plates.
Some embodiments and comparative example
Influence of the consumption of tourmaline to properties of product, i.e. method and step be the same as Example 6 are determined, the difference is that only and change
Become the consumption of different tourmaline, as shown in table 2：
Influence of the consumption of the different tourmaline of table 2 to properties of product
| Embodiment 6 | Embodiment 11 | Embodiment 12 | Embodiment 13 | Embodiment 14 | Comparative example 7 | Comparative example 8 | |
| The consumption (part) of tourmaline | 3 | 10 | 2 | 5 | 9 | 0 | 30 |
| Density | 1.51 | 1.51 | 1.51 | 1.51 | 1.51 | 1.51 | 2.6 |
| Water absorption rate | 17 | 17 | 17 | 17 | 17 | 17 | Undetermined |
| Aobvious porosity | 27 | 27 | 27 | 27 | 27 | 27 | Undetermined |
| The efficiency of purifying formaldehyde | 81 | 90 | 79 | 84 | 88 | 76 | 97 |
Conclusion：In the range of total amount 10%, the amount of tourmaline is directly proportional to eliminating the efficiency of formaldehyde.To density, water suction
Rate, aobvious porosity do not produce influence.In the case of 10% scope, it is more that tourmaline adds, resulting diatom pottery clay plates
Density is then higher, water absorption rate and aobvious porosity is lower, purifying formaldehyde efficiency is higher.
