Analysis of the main points of water-based industrial paint construction.

Entering the era of water-based coatings, they are often divided into two positions of support and opposition, each of which is obsessed with their own views. If we don't discuss it today, we can make an entry from the industrial sector to see what the difficulties are, and we can hope to inspire you.
water-based coatings are usually composed of water-based resins, pigments, additives, water (solvents), but some water-based coatings may also contain some organic solventswhen the resin is synthesized or for formulation
.water-based coating has its own advantages and disadvantages, the following mainly from the coating itself difficulties and construction difficulties of the two parts of comprehensive analysis.
difficulty with coating
water-like primer
1. Site construction, hanging, flash rust, etc.;
2. Paint film performance;
3. Matching with the bottom layer.
water-water paint
. 1. Site construction, flow hanging, extreme foaming, etc.;
2. Matching with putty and covering of putty;
3. Paint film appearance, gloss, freshness, fullness,
4. Paint film repairability, such as polishing, wax-resistant polishing, and later water-based paint or solvent-based repair paint, water-based paint repair will often appear dry, long repair cycle problems, while prone to repair edge color difference, such as solvent-based repair, may appear repair positional swelling problems, which requires water-resistant paint solvent-resistant.
construction "change"
. 1. Overcome the inertia in conventional oily paint spraying, adjust the operating habits of solvent-based paint construction,
2. Wet film appearance judgment, do not need to be directly sprayed to surface level, if the original habits directly sprayed to surface level, will produce paint surface hanging;
3. The table drying time between coatings is strict, must wait for a coating table dry to sublight before the next coating can be sprayed, otherwise the paint is out of light, flow hanging obviously, much higher than solvent-based paint;
4. Water-based paint in solvent (moisture) volatility process, the rise of solid content and oily paint is very different.
the old line "oil to water" recommendations
conditions allow, the construction of new lines, it is best to consider the constant temperature and humidity coating environment and flash intervention heat baking mode. Old line transformation, taking into account the actual situation, can be discussed appropriate relaxation, not strict requirements of constant temperature and humidity, to meet the following conditions, can be normal use of water-based paint coating:
1. increase the pumping and wind delivery system, if not, especially in winter low temperature and high humidity conditions, even if can not heat up, but must be dehumidification;
2. Coating, flat baking equipment,
long-term consideration, it is best to change to stainless steel material,
so as not to rust;
the difficulty of water-powered industrial paint, we cannot deny it. It is reported that water-based industrial paint in the automotive field as well as paint applications have been quite mature, we can use the experience of this field in the process of perfecting water-based industrial paint, to achieve the maturity of water-based industrial paint!
