The performance and effect of water paint

1, water paint adhesion how?
adhesion is better than paint (excluding poor water paint), because wood hydro-hydro, water-based resin can penetrate into the wood fiber, film and form a huge grip.
2, why is water paint more yellow-resistant than paint?
because the water paint film does not contain yellow-prone substances, and oily nitro contains a large number of nitro cotton, PU contains a large number of TDI and other yellow-prone substances.
3, water paint is very flexible?
softness of the water paint is incomparable, because the paint film is almost all pure resin cross-linked, and nitro contains a large number of nitro cotton, PU contains a large number of easily broken chain TDI

4, water paint will cause wood cracking?
, in a sense, it is easy to achieve a certain anti-cracking function.
Wood has hydro-hydrogenic properties, nano-scale water-based resin can seep into the material with the wood catheter to a certain depth, after drying and curing, these seepage resin can be well glued wood fibers, should play a role in slowing wood cracking, rather than paint-coated furniture will be more prone to cracking.
5, water paint will improve the water content of wood?
No, as follows:
(1) Wood moisture content and wood moisture content calculation:
to a piece of 1M x 1M, thickness of 1CM solid wood calculation, the general furniture enterprises used solid wood in the processing water content of 12% (water content of wood moisture weight, and the weight of the de dried wood percentage).
(2) Water content after wood paint:
theory is calculated as follows, according to the water paint solid content of 40% (i.e. 60% of which is water), artificial spray volume 10m2/kg and spray utilization rate4 0% (maximum) calculation, equal to the amount of water sprayed into the wood is 24g/m2, after spraying the natural drying process, about 50% of the water will be volatile, and finally the wood water adsorption of about 12g/m2.
(3) wood once the first layer of coating film closed, the second layer of sprayed water can not enter, unless the first layer of primer is not waterproof.
(4) wood on the positive surface of the actual water absorption is very poor, moisture into the wood is mainly the end, if the furniture manufacturing process to be closed as early as possible, the water content of the wood is more difficult to change.
the hardness of the water paint reached by 6 and 6?
the hardness of a single part HB to 1H, equivalent to nitro paint, and the hardness of two parts 1 to 2H, i.e. the same as PU paint.
: Some single-group products with a certain amount of hydroxyl, such as the use of adaptive curing agents, often can improve an HB hardness
7, water paint resistant to cold water?
poor cold water (the vast majority), will white shadow, bubble or seep in, etc. , good cold water (very few).
8, water paint resistant to 100 degrees C boiling water?
(most of them), will white shadow, bubble or seep in, etc. , good no response (very few).
9, water paint resistance to acid and alkali and other protection?
can pass the same national standard test as paint, and some items are better than paint, such as alcohol resistance.
10, water paint can do the paint luster?
light is less than a minute, such as a single-group water paint can reach 8 minutes, two-parts can reach 9 minutes light, but matte can be more dumb than paint.
11, water paint weather resistance, resistance to newness?
is much better than paint, about twice as much, because the resin of water paint cross-linking is not the same, so when used for outdoor painting, water paint than paint advantages more obvious.
12, water paint has a stronger permeability to wood?
, wood is hydro-hydrogenic, and the resin of water paint can easily seep into the wood and bond the wood fibers, which will help the wood to resist cracking.
13, water paint can have the clarity of paint?
, of course, also look at the clarity of the resin itself and cross-link density, paint powder will also affect the clarity of the paint film.
14, water paint smoothness or feel?
good, the same as the paint, the same as the paint.
15, why is the water-like coating film the most consistent coating film of wood?
because the water paint film is a wrinkle film, the paint is a balance film, water paint can more meet the deformation of wood around the clock.
16, water paint's fast hardness than paint slowly represents a slow water walk?
No, in fact, after the water paint coating, moisture in the packaging before almost evaporated, fast hardness is slow, because such as water-like plasticizers and other additives volatile too slowly caused, such additives than oily similar substances much slower.
17, why is the water paint film getting harder and harder?
because as some additives evaporate, water-based resins adhere to each other, will be more and more tight, naturally the paint film hardness is getting higher and higher.
18, water paint wear resistance represents hardness?
does not represent, but there is a certain relationship, high hardness can improve scratch resistance, but wear resistance may be related to film quality, how much water wax added.
is there so little dust when it is polished with water paint?
because the resin has a better hydro-hydropority than oily resin, flying dust easily absorbs moisture from the air and sinks, so the use of water paint will appear to be particularly clean air.
20, water paint can not be polished with water sandpaper?
Because the water sandpaper is mainly used for the operation that needs to be polished with water, sanding methods and powdering methods are also different from dry sandpaper, sanding is particularly prone to heat, its own water paint film resin is more, more susceptible to heat replastication, coupled with water sandpaper powdering capacity is poor, resulting in very easy sandpaper.
21, in wet weather, water paint than paint which is more white?
this has a great relationship with their respective quality performance, the two are the same quality of the conditions, or paint is easier to whiten.
22, how closed is the water paint?
Very well, when the water is painted into a film to a stable period, its permeable wood fiber resin and surface resin will be closely linked, and will not be slightly cracked by the creep of wood, it will have a better closure than paint, of course, the use of poor resin is not included.
