Percentage and number are calculated by weight.
Embodiment 1：Aqueous woodware paint is tested
The installation of device：
1. water smoke emitter：
(1) guidance panel, the power supply for control device water smoke amount and water smoke temperature, and water smoke emitter
Switch.Water smoke amount is divided into two grades of 280-380mL/h, 320-420mL/h；Temperature control is divided into room temperature water smoke
With 40 DEG C of two grades of water smokes；
(2) water smoke emission port, water smoke is sent from the emission port, and emission port needs closely to be connected with support, to prevent
Gas leakage；
(3) filter, to filter impurity in water smoke.
2. many slot jig frames of metal, for inserting 4 pieces of 30 × 40cm models, thickness is no more than 5mm,
And one piece of 30 × 30cm model, thickness is no more than 5mm.
3. jig frame bottom bracket need to be totally-enclosed to accept condensed water, bottom instrument damage is prevented.Support assorted
Guiding gutter, condensed water is introduced into waste water collection device.
4. model drying frame：For drying model.
The step of test, is as follows：
1st, prepare ground, clean out, it is standby；
2nd, prepare paint film, the preparation of paint film is carried out according to the design manner of application of coating, test sample A, B,
C and D brush 3 road paint films；After per pass is painted with, interval is specified after repainting time one after application；
3rd, 16h is maintained under the conditions of 23 ± 2 DEG C, 50 ± 5%；
4th, the model for finishing maintenance is installed in test device slot, and ensures that model has been completely installed to
Position, obvious gap is not left；And equipment is illustratively assembled build completion；
5th, vapor (steam) temperature is set to adjust to 320-420mL/h as 40 DEG C, quantity of steam；
6th, opening device；
7th, after follow-on test 8h, test case is checked, and record.
Test result is as follows：
Test result figure is as shown in Figure 2.From test result as can be seen that test carry out 3h when, sample
Product A and sample B occur turning white and foaming phenomena；When test carries out 4h, there is foaming phenomena in sample C,
Place the 8-16 hours paint film crackings after drying naturally.Sample D phenomenons without exception after test 8h is carried out,
Place the 8-16 hours phenomenons without exception after drying naturally.
Sample A and B water resistance can be seen that by above test result poor, to meet with water smoke long when paint film
Time infiltration after, exist turn white, foaming phenomena；And after sample C tests, foaming phenomena occur, work as paint film
After drying, paint film ftractures, and illustrates that the sample pliability is poor, after there is the stress in recovery process,
Paint film ftractures.Coating surface is smooth after sample D tests, no foaming, the phenomenon such as cracking.
Therefore, from this four samples, D samples are filtered out as subsequent development raw material.
