With the rapid development of the economy and people's awareness of environmental protection, water-based wood paint by virtue of its green advantages, by more and more owners of favor. Especially in the last two years, the research and development and innovation of water-based wood lacquer products are growing rapidly, and their popularization and application are of great significance to the rational use of resources and the improvement of the environment.
today, let's talk about the seven main points of water-like wood lacquer construction, how to make the construction more handy
China
.
01 White blank treatment
effect: effectively remove stains, dust and burrs on the surface of the plate, so that the plate is cleaner and smoother, which is suitable for construction.
operation method: choose 240 to 320, sandpaper scrub film, lines, grooves and other parts, you can use cotton yarn grinding, transparent coating needs to be polished in the direction of wood grain.
: protect the surface of the plate, not sand through.
requirements standards: before brushing primers, white blank treatment to achieve smooth and clean, to ensure the smooth progress of the next process.
02 sheet closure
: the plate is closed to prevent contamination of the plate. At the same time, to prevent excessive moisture absorption and looseting of the plate, to slow down the deformation of the plate, to enhance the adhesion between the paint film and the plate, to save the amount of primer, to prevent the paint film subsidence, to enhance the hardness of the paint film, to slow down the plate formaldehyde and other harmful substances volatile outwards.
operation method: select the plate closure agent products, according to the ratio requirements on the packaging deployment, even brushing, once can be.
:
to ensure that the water content of the plate between 8% to 12%, such as water content is too high, easy to cause whitening and other phenomena;
It is best not to go through bleaching, otherwise direct painting is easy to cause yellowing, must be after pre-treatment (with water plus a small amount of washing powder to be completely dry) and then paint;
, for light color plates need to use yellow-resistant closed agents;
, for dirtier plates, should first be cleaned with solvents;
requires standards: uniform brushing, no flow, no leakage brush.
03 Filling treatment
effect: scraping putty, filling wood holes, reducing the amount of wood paint, improve the flatness of the lacquer film, easy to work behind.
operation method: the selection of matching nail hole putty and water-based putty;
filling process, only fill the wood eye, do not fill the wooden diameter, fill the putty into the wood eye, and then scrape hard to ensure that the putty is fully pressed into the wood eye, and finally choose 240 to 320 s sandpaper for grinding, the wood diameter putty completely clean.
requirements standard: to ensure that nail eyes, wood eye scraping in place, standing 1m away, not see nail eyes, and texture clear.
04 primer construction
: fill wood holes, increase the thickness of the paint film.
operation method: after opening the tank will be the primer stirred evenly, according to the requirements of the deployment, if the wet and wet construction, that is, after the paint film table dry, the coating between not polished, and then apply the primer, the time requirements are controlled within 4 hours;
requirements of the standard: uniform brushing, no hanging phenomenon, in a fully enclosed coating, the wood eye fill flat to no wood holes.
05 Grinding Treatment
: by polishing, the entire paint film surface smooth, forming a glass-like hair, enhance the adhesion between layers.
: Note that in different processes, different types of sandpaper should be selected for grinding work -
white blank treatment: 240 to 320;
primer polishing: 320;
finish primer polishing: 600;
finish polishing: 600 to 800;
finish polishing: 1500 to 2000;
precautions: transparent coating should be polished in the direction of wood grain; wood threading, as far as possible, the use of special cotton yarn.
requirements standards: smooth, white blanks without stains, primer without bright spots, finish without particles, surface gloss uniform.
06 Environmental cleaning
: by finishing cleaning, reduce particles on the surface of the lacquer film, so that the surface of the lacquer film has a better coating effect.
operation methods: first of all, you can use a vacuum cleaner to clean the ground dust, choose a brush to clean the surface of the coated object, and then wipe it clean with a semi-dry towel, the construction of floor paint should be after dusting for a period of time after the construction, it is recommended to use a special dust removal cloth wipe.
requirements: every process must be clean, gently touch the surface of the coating by hand, to ensure that there are no particles.
07 paint construction
: decoration, protection, to ensure the final paint film effect.
operation method: open the can before construction fully stirred well, according to the packaging requirements for deployment, with paint filtration, should be set aside for 10 to 15 minutes, choose high-quality wool brush or spray.
requirements of the standard: brush uniform, no flow hanging, leakage brush;
