Water-like wood paint construction precautions - ambient temperature and humidity control

In China, the existing water-based wood coatings market application areas are: furniture, wooden toys, picture frames, handicrafts, molded doors, bamboo, rattan and so on. Although the current water-based coatings have been more and more extensive attention and application, but the popular application of water-based paint still has some problems to be optimized and solved, such as low solid content relative to traditional solvent-based coatings, slow drying, long film-forming time, environmental temperature, humidity sensitivity, high temperature and humidity control requirements of the construction environment, these need to be through the formulation of technical improvements and construction process adjustment to solve. Today, the small editor to share with you the furniture water-like wood paint production and construction can not be ignored - environmental temperature and humidity control
China
.
ambient temperature and humidity control:Compared with oily coatings, the ambient temperature and humidity control of water-based wood coatings play a decisive role in the construction performance and lacquer film performance of water-based wood coatings. Too high or too low temperature and humidity may lead to the appearance of paint film ills, such as dry incomplete, hanging, hair hazy, pickles, orange peel, foaming and so on. If the best construction conditions can not be met when the environment is to be coated, the coating effect should be tested first to be satisfied, so as not to cause later rework.
water-like wood paint construction environment temperature and humidity control instructions:
humidity
control coating site relative humidity between 70%, the higher the humidity level is better, but the slower the drying speed, to achieve a balance between them. (Water can be sprayed to humidification, dust reduction)
Pollution
the higher the humidity of the coating environment spraying, the slighter the pollution phenomenon, on the other verse, the lower the environmental humidity when spraying the more serious the pollution phenomenon.
Heating
For the northern cold area furniture factory coating site heating difficulties, you can consider the paint using heating method construction, it can increase the smoothness of the coating and perforation, reduce water, speed up drying. (Single liquid type does not shorten the use time due to increased paint temperature, which is the main reason for the use of single liquid type in the production of automatic
). Furniture factory coating scene analysis and response
Scenario 1:
low temperature low humidity: coating ambient temperature at low temperature low humidity;
response: A, construction environment humidification, B, paint (water isolation) heating, C, the use of construction site equipment heating, D, spraying when using a number of thin coating methods, while thin coating control coating volume can also avoid hanging and other paint diseases.
scenario 2:
high temperature high humidity: coating ambient temperature at high temperature and high humidity, water-based wood coating although can be dry, but the paint film may appear slow dry, white foggy, hazy and so on.
response: A, paint to reduce the proportion of water, heating dehumidification, temperature increase humidity is reduced;
scenario 3:
low temperature high humidity: coating ambient temperature low temperature high humidity conditions when the paint film may appear slow dry, back sticky paint disease.
: A, flexible use of paint (water isolation) heating;
Dabao water-based wood paint coating effect
water-based wood paint drying temperature and humidity control three steps:
A, drying initially requires the environment temperature and high humidity, which is good for paint into the hole, wet, level. (The ambient temperature is too high, the temperature is too low may cause the water-like paint film table dry too fast, hair hazy and other paint film ills appear;
)
B, drying medium-term requirements of the environment high temperature low humidity, the coating began to gradually dry. (The drying of the water-based lacquer coating requires a gradual process of circulation, too slow/too fast drying will have an impact on the materiality of the coating such as: gloss is not equal, tweezers, orange peel, cracking and so on).
C, drying late requires high temperature and low humidity environment, accelerate the thorough drying of the coating. (Although the water-like wood lacquer watch is dry, it takes a long time for the water in the paint film to evaporate completely, usually ten to fifteen days after drying to reach the final test material (winter low temperature time should also be appropriately extended), before the coated wood should be treated with care, no cooling or waiting time is not enough to stack, cover, collision, so as not to cause damage.) (The moisture content of wood before white coating and the same or relatively low moisture content of the paint film indicates that the water in the paint film has been
completely steamed out, to be dried



The role of the humidifier is to increase the air humidity in the space, to prevent static electricity, dust, extend the drying time of the water-like paint pre-paint film table, conducive to surface leveling and perforation.
only by following the above temperature and humidity control steps can we truly solve the problems faced by water-like paint production and drying. Make water-quality paint furniture products in the production and construction to do: energy-saving, efficient and stable.
