SU304, matrix are equipped with the protrusion equidistantly arranged, form gap between the protrusion.The height of the protrusion is 1.3mm,
Raised length and width 4.4*4.4mm, spacing 2.2mm.
A kind of toothbrush cleaning force test method, includes the following steps:
(1) by the filling container of slurry injection electric paint spray gun, electric paint spray gun is sprayed to the surface of dental mold and is starched
Material, makes slurry equably be sprayed at all surfaces of dental mold, the part of part and gap including protrusion；
(2) dental mold of step (1) is placed in insulating box；Water paint is set to reach surface drying and inner dry；
(3) dental mold of the brush head of toothbrush and step (2) is fixed respectively, certain number of brushing teeth blots water after flushing
Point；
(4) dental mold of step (3) is scanned, analyzes the color accounting on dental mold surface, analyze remaining color
The area of slurry accounts for the area on dental mold surface, calculates the cleaning force X of toothbrush；
And/or the quality of the slurry brushed off is calculated, the cleaning force Y of toothbrush is calculated, to evaluate the cleaning force effect of toothbrush
Z。
Specifically, in step (1) electric paint spray gun nozzle face dental mold, nozzle is at a distance from dental mold
10-30cm, injecting time are 5-40 seconds.Spray gun and/or dental mold can be moved or not moved in course of injection.
The time that insulating box is placed in step (2) is 5-10 minutes, and temperature is 40-80 DEG C, is then cooled to room temperature.
As a preferred embodiment, the slurry is in yellow, since yellow helps to increase mill base and dental mold
Color difference between matrix keeps calculated yellow mill base area more accurate so that image is shown after scanning.
Specifically, the slurry includes white coating and yellow mill base.It is highly preferred that the white coating is acrylic compounds
White coating.The white coating and yellow mill base are commercially available product.The yellow mill base accounts for the 4-10% of slurry total weight.
As a preferred embodiment, auxiliary agent, such as drier can also be added into the slurry, after spraying
Water paint rapid draing.
The process brushed teeth described in step (3) is transversely to move brush head with longitudinal each movement or simultaneously, to make to brush
Relative displacement occurs between head and dental mold, certain number is preferably 200-600 times, and the frequency brushed teeth is 50-150
Secondary/min.
The cleaning force calculation of step (4) toothbrush are as follows: set the elemental area of mill base before testing as 100%, remnants
The area of mill base is A%, and the calculation formula of toothbrush cleaning force X is X (%)=100%-A%.
Alternatively improvement project, the cleaning force calculation of the toothbrush are as follows:
Further include step (21) after step (2): weighing weight A after the dry cooling of the dental mold of step (2)；Step
(4) further include: weigh weight B after the dry cooling of dental mold, the calculation formula of toothbrush cleaning force Y is Y (g)=(A-B) *
100%/A.By calculating the quality of the slurry brushed off, the cleaning force effect of toothbrush is further evaluated.
It is further preferable that the evaluation method of the cleaning force effect Z for evaluating toothbrush are as follows: the power of setting toothbrush cleaning force X
Weight is a, then cleaning force effect Z=a*X+ (1-a) the * Y of toothbrush.Preferably, a=50%.
It is further preferable that the fixed form of the brush head of toothbrush described in step (3) is to cut the brush head of manual toothbrush,
And fixed by clamping device, it is moved under the drive of clamping device；Either, electric toothbrush and clamping device are fixed, is being pressed from both sides
It holds and is moved under the drive of device, and electric toothbrush is connect with pressure-detecting device, to detect electric toothbrush in moving process
In to the pressure of dental mold.
As a kind of prioritization scheme, it is scanned in step (4) using the printer with scanning function, camera can be overcome
Equal shootings equipment needs the problem of being shot under standard light, reduces shooting color difference bring test error.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of dental mold used in the embodiment of the present invention 1.
