Paying attention to environmental protection is the policy of the state and the responsibility of enterprises. Pay attention to indoor environmental protection! It is the responsibility of every producer. KEPAI wooden door teaches you a trick to distinguish the painting type and paint classification of wooden door, and popularize the basic knowledge of painting for everyone

according to the surface treatment method, the paint coating of wooden doors can be divided into five categories: open paint, closed paint, baking paint, paint spraying and paint free

process introduction and features:

open paint: open paint retains the pore structure of natural wood grain, clearly presents wood texture and wood holes, with matte texture. This way can highlight the wooden pipe holes, making its surface uneven and more three-dimensional, more close to the natural state

open paint requires higher cost and spraying technology, because it is difficult to form at one time, requiring six to seven times, or even more than ten times

open paint is only applicable to wood with large pipe holes

sealing paint: completely seal the brown holes on the wood surface with primer, and the paint film is plump and thick, making its surface complete and smooth. Generally, the paint is thick during the second painting, which is convenient for grinding and leveling. Sealing paint can be applied to all wood substrates

open paint and closed paint show two different paint effects. The closed paint surface is thick

paint baking: paint baking refers to the method of repeatedly spraying paint on the surface of the plate and repeatedly placing it into the drying room to dry the plate at high temperature. Because the drying room heating method is adopted, the temperature is stable and uniform. Therefore, the wooden door baked by the paint baking method has a smooth surface, will not retain oil stains, and can maintain bright colors even if it is used for a long time. It is generally used to improve the overall brightness of the board, and it also has excellent waterproof effect

painting: apply putty directly on the plate, then paint on the putty, and finally dry it naturally. Painting is better than cheap

compared with the products with baking paint process, the surface of the products with paint spraying is rough, the overall color is not uniform, the color is not full, and the paint film is easy to fall off after a long time

paint free: compared with the above four paint types, paint free means that paint is not required, but refers to PVC veneered doors. Paint free refers to the use of PVC veneer vacuum plastic absorption process on the surface of solid wood composite doors or molded doors, which saves the painting process and allows the finishing coat to be formed at one time during construction. The PVC used here belongs to plastic decorative film, and the color and pattern can be selected according to preferences. The surface of the finished product is smooth and bright, but the wear resistance and flame retardancy are poor, and it is easy to crack, discolor and age

the use of PVC veneer for paint free will make the door leaf poor in air permeability and enhance the emission time cycle of harmful substances in the inner core of the door leaf

KEPAI wood door paint is divided into polyurethane paint (PU paint) and UV curing paint

polyurethane paint (PU paint)

polyurethane paint (PU paint) is one of the most widely used paint varieties in domestic wood door enterprises at present. It has good comprehensive properties, and the paint film is tough and wear-resistant. It has good performance in both fullness and color brightness

uv curable coating

uv curable coating has the effect of preventing pollution and saving energy. The coating has excellent chemical and physical properties, and has the characteristics of rapid curing. It is widely used in the production of furniture and wooden doors, wooden floors, cabinet panels, etc. as a new processing technology, UV has been commercialized for more than 25 years

among the hazards of interior decoration materials, formaldehyde mainly comes from the urea formaldehyde resin in the composite board materials used for decoration, which will form free formaldehyde gas and release it into the air, and the release period of formaldehyde is 3 to 15 years. Therefore, the PVC film used in the fully enclosed paint free door will prolong the evaporation time of urea formaldehyde resin in the material and bring more insecurity to health. You can't just rely on publicity gimmicks

benzene: benzene and its homologues toluene and xylene are colorless and aromatic liquids. It is mainly produced in thinners of oily paints, such as banana water and Tianna water, which contain harmful carcinogens such as benzene and xylene. However, benzene is very volatile and can be eliminated in 2 months

wood door paint is only one kind of auxiliary materials, and wood door coating also involves various auxiliary materials such as plates and adhesives. It is also the key for enterprises to control the environmental protection index of plates and the environmental protection performance of adhesives and other auxiliary materials in the upstream supply chain. Only by focusing on the environmental protection of products from the source and reducing the emission of harmful substances within the enterprise can the final products meet the environmental protection requirements

on May 1st, 2018, the compulsory inspection standard of KEPAI wooden doors was comprehensively improved, and the relevant products of KEPAI wooden doors must meet the requirements of the new standard: formaldehyde emission limit in indoor decoration materials, wood-based panels and their products (GB18580-2001)

KEPAI wooden door won the "2017 top ten environmental protection brands of Chinese wooden door"
