Embodiment one
The compatibility cartridge A of Q2612A discovery when carrying out printing test on the printer of HP1010 is worked as printing by researcher
To after page 200, there is the phenomenon that carbon dust glues drum, occurs printing white point on test paper.
The defects of above-mentioned compatible cartridge A carbon dust a is taken to be modified processing, processing method is as follows.
1.1,98.9 parts (based on parts by weight, similarly hereinafter) of defect carbon dust a, 0.5 part of alumino-silicate, the two of 0.5 part are taken
Silica and 0.1 part of zinc stearate.
1.2, above-mentioned material is added in the mixing machine of adjustable speed, first mixed on low speed 1min stands 1min；Mixed at high speed again
5min stands 1.5min.The humidity of hybird environment is controlled in mixed process less than 70%, temperature is not higher than 30 DEG C.
1.3, after the completion of mixing, 200 mesh screens of mixed material are sieved, obtain modified carbon dust a.
Obtained modification carbon dust a is added into Q2612A powder box clean in advance, is put into HP1010 printer
Test, tests page 2000 of the entire service life, viscous drum problem does not occur.
By carrying out physical property measurement to defect carbon dust a and modified carbon dust a, the correlation data in table 1 is obtained.
Table 1
| COE/% | MVD/μm | P5/% | |
| Defect carbon dust a | 15.3 | 10.02 | 75.2 |
| Modified carbon dust a | 6.6 | 10.01 | 74.98 |
Wherein, COE is a kind of representation method of mobility, after referring to the work of specialized equipment unit time, stays in carbon dust amount on sieve
Percentage.Percentage is smaller, and mobility is better.
MVD value namely D50 value, its physical significance are that partial size is greater than its particle and accounts for 50%, and partial size is less than its particle
It accounts for 50%, D50 and is also known as average grain diameter.
P5 is the percent by volume that partial size is greater than 5 microns in distribution of particles.
The average grain diameter that can be seen that defect carbon dust a from the data of table 1 is 10.02 μm, and is greater than 5 μm of particle accounting
Only 75.2%, illustrate that little particle is excessive, while mobility is 15.3%, poor fluidity causes the transferring rate of defect carbon dust a low,
It is adhered to the load that cleaning doctor is aggravated on drum, easily so as to cause viscous drum.Compared with defect carbon dust a, mobility obtains modified carbon dust a
To very big raising, solve the problems, such as that defect carbon dust a's is viscous bulging after improving mobility.
Embodiment two
The compatibility cartridge B of Q2612A discovery when carrying out printing test on the printer of HP1020 is worked as printing by researcher
To after page 1000, there is the phenomenon that carbon dust glues drum, occurs printing white point on test paper.
The defects of above-mentioned compatible cartridge B carbon dust b is taken to be modified processing, processing method is as follows.
2.1,98.3 parts of defect carbon dust b, 1 part of alumino-silicate, 0.6 part of cerium oxide and 0.1 part of zinc stearate are taken.
2.2, above-mentioned material is added in the mixing machine of adjustable speed, first mixed on low speed 10s stands 1min；Then high speed is mixed
1min is closed, 1min is stood；Mixed on low speed 10s again stands 1min；Last mixed at high speed 1min, stands 1min.It is controlled in mixed process
For the humidity of hybird environment processed less than 70%, temperature is not higher than 30 DEG C.
2.3, after the completion of mixing, 200 mesh screens of mixed material are sieved, obtain modified carbon dust b.
Obtained modification carbon dust b is added into Q2612A powder box clean in advance, is put into HP1020 printer
Test, tests page 2000 of the entire service life, viscous drum problem does not occur.
By carrying out physical property measurement to defect carbon dust b and modified carbon dust b, the correlation data in table 2 is obtained.
Table 2
| COE/% | MVD/μm | P5/% | |
| Defect carbon dust b | 5.3 | 9.5 | 68.52 |
| Modified carbon dust b | 6.2 | 9.47 | 68.40 |
The P5 that can be seen that defect carbon dust b from the data of table 2 is too small, and particle diameter distribution is uneven, leads to viscous drum, in defect carbon dust
In the case of the granularity of b can not change, by adding alumino-silicate, cerium oxide, zinc stearate into defect carbon dust b, it can play pair
The effect of grinding, the polishing of defect carbon dust b, therefore the modification carbon dust b obtained can solve viscous drum problem.
Embodiment three
The compatibility cartridge C of Q2612A discovery when carrying out printing test on the printer of HP1022 is worked as printing by researcher
To after page 1500, there is the phenomenon that carbon dust glues drum, occurs printing white point on test paper.
The defects of above-mentioned compatible cartridge C carbon dust c is taken to be modified processing, processing method is as follows.
3.1,98.3 parts of defect carbon dust c, 1.5 parts of alumino-silicate and 0.2 part of zinc stearate are taken.
3.2, above-mentioned material is added in the mixing machine of adjustable speed, first mixed on low speed 3min stands 3min；Then high speed is mixed
8min is closed, 5min is stood；Mixed on low speed 3min again stands 3min；Last mixed at high speed 8min, stands 5min.In mixed process
The humidity of hybird environment is controlled less than 70%, temperature is not higher than 30 DEG C.
3.3, after the completion of mixing, 200 mesh screens of mixed material are sieved, obtain modified carbon dust c.
Obtained modification carbon dust c is added into Q2612A powder box clean in advance, is put into HP1022 printer
Test, tests page 2000 of the entire service life, viscous drum problem does not occur.
By carrying out physical property measurement to defect carbon dust c and modified carbon dust c, the correlation data in table 3 is obtained.
Table 3
| COE/% | MVD/μm | P5/% | |
| Defect carbon dust c | 3.24 | 7.43 | 80.22 |
| Modified carbon dust c | 4.23 | 7.39 | 80.13 |
The MVD value that can be seen that defect carbon dust c from the data of table 3 is less than normal, causes printing blackness excessively high, and powder amount of giving up increases, and adds
Give up powder scraper load again, causes viscous drum, when granularity can not change, by adding alumino-silicate, hard into defect carbon dust c
Resin acid zinc can play the role of the grinding to defect carbon dust c, polishing, therefore the modification carbon dust c obtained can solve viscous drum and ask
Topic.
The present invention also provides a kind of cartridge, it is provided with the powder cabin for containing carbon dust in cartridge, is provided in powder cabin
The modification carbon dust of the embodiment of the present invention one, two or three.
Technical concept of the invention is not limited in above-described embodiment, can also design according to the present invention obtain it is many not
Same concrete scheme such as simply adjusts the proportion of each material, is simply adjusted to the speed and time that stir when mixing
It is whole etc., within the scope of these minor alterations and equivalent transformation should be included in described in claim.
