IV. Procesul de operare:

(eu) Fluxul procesului:

(2) Procesul de operare:

1. Tratament de bază: îndepărtați praful și petele de pe suprafața lemnului. If there are oil stains, can be scrubbed with thin material. The depth of the cap into the wood surface should be greater than 0.5㎜. Lustruiți suprafața de bază de-a lungul fibrei lemnului, nu slefuire orizontala sau slefuire oblica. După șlefuirea și șlefuirea tuturor obiectelor plutitoare, ștergeți suprafața curată, cum ar fi culoarea suprafeței lemnului ar trebui să se facă un tratament de albire (agent de albire în general cu peroxid de hidrogen: amoniac =4:1).

2. Ulei de etanșare, lustruire cu chit: primul ulei de etanșare și chit de lustruire netedă.

3. Brush THE FIRST TIME varNISH: varnish should be painted along the direction of wood grain, nu perie orizontală, perie oblică, leakage brush and flow fall, și trebuie să mențină grosimea corespunzătoare. Varnish after drying should be an interval of one day, to be fully dry, particulele și tepii zburători, toate deformate, propice lustruirii.

4. Culoare: Frecați uniform cu o cârpă moale albă.

5. Brush the second to four times of varnish: check the color, repair effect, meet the requirements, you can apply the second to four times of varnish. After each time the varnish is applied to dry, it should be sanded with 1# old wood sandpaper, and the fine particles on the film should be worn off and wiped clean to apply the next time the varnish.

6. Color MATCHING and color correction: IF the local color is found to be inconsistent with the sample color after the fourth time of varnish, the color matching and color correction should be carried out according to the sample color. Color and repair can use oil color or color essence. The putTY scar with smaller area, can use oil color generally, can use color essence to the color of larger area is inconsistent.

7. Sanding: After the fourth time varnish is dry, use 280# ~ 320# water sandpaper to sanding, necesitând măcinare lină și meticuloasă, and grind all parts to, pay attention to the edges and corners can not be white or worn. After sanding, wipe off the sewage and wipe clean with clean water.

8. Brush the varnish for the fifth time and the sixth time: as the last second time of the varnish grinding process, the application method is the same as above. În același timp, the sixth paint is required to be brushed in succession when the fifth paint is not completely dry, which is conducive to the plenteness and smoothness of the coating film, and is not easy to be worn or worn out in the grinding back.

9. Grinding back: After the last two times of the cover paint is dry, use 400# ~ 500# water sandpaper dipped in soapy water to polish the gloss of the coating surface. La măcinare, forța ar trebui să fie uniformă, necesitând măcinare lină și meticuloasă, and the surface gloss should be grinded to and smoothed. Ștergeți și uscați după măcinare.

10. Ceară de nisip: în primul rând, ceara de nisip cu kerosen în terci, with a clean lint dipped in sand wax, de-a lungul direcției granulației lemnului frecare înainte și înapoi, until no bright star so far. Puterea ar trebui să fie egală, marginile și colțurile trebuie frecate, iar marginile și colțurile nu trebuie uzate. In cele din urma, use a clean lint cloth to wipe the surface of the floating wax, and use the polishing machine to force evenly.

11. Wipe POLISH wax: cu o cârpă albă curată va lustrui pachetul de ceară în interior, repeatedly rub on the paint coating, wipe, wipe, până luminează.

V. Quality Standard:

(eu) Elemente de control principale:

1. Varietatea, type and performance of the paint selected for the paint project should meet the design requirements. The content of harmful substances in the paint and the selection of diluents need to comply with the relevant provisions in the “Limit of harmful substances in solve-based wood Coatings for interior decoration Materials” (GB18581-2001) and the “Code for Indoor Environmental Pollution Control of Civil Construction Engineering” (GB50325-2001).

2. The color, gloss and pattern of the paint project should meet the design requirements.

3. The paint project should be painted evenly, firmly bonded, and must not leak paint, through the bottom, peel and anti rust.

4. The moisture content of the wood base is not greater than 10%.

ASTM D412-0 “Retragere de șlefuire a lacului de suprafață din lemn”

(II) General items:

1. The finish quality and inspection method of wood surface varnish should comply with the following table.

Method for quality and inspection of abrasive finishing of wood surface varnish

General finishing advanced finishing inspection method of the project

1 Color is basically uniform uniform observation

2 wood grain brown eye scraping, wood grain clear brown eye scraping, wood grain clear observation

3 luciu, smooth gloss is basically uniform, smooth no block feel gloss uniform, smooth observation, hand touch inspection

4 Brushless brushless observation

No observation is allowed in the obvious places OF wrapping edge, flowing drop and wrinkled skin

Observe the cleanliness of doors and Windows, hardware and glass

The CONNECTION between the coating and other decoration materials and equipment should be consistent, and the interface should be clear.

Vi. Finished Product Protection:

1 Brush oil before first clean up the surrounding environment, to prevent dust flying, affect the quality of paint.

2 Paint each time to pay attention to environmental hygiene, windy weather and indoor cleaning should not be painted. Doors and Windows fan brush after each paint, the doors and Windows with a spike hook or wedge fixed, avoid sticking bad paint coating.

3 Pay attention not to knock and stain the paint surface. The oil stains on the ground should be cleaned in time.

4. After painting is finished, special personnel should be sent to take care of it.

Seven, should pay attention to the problem:

1 angular putty is not smooth: mainly putty is not full, and caused by contraction. The solution is to fill the putty, until it reaches the level, dry with sandpaper polishing level.

2 worn out edges and corners: mainly the edges and corners are easy to wear out and worn out. Do not use too much force when grinding water sandpaper and sand wax, and keep the edges and corners intact.

3 Flow fall: mainly uneven brushing, coating too thick, oil brush with too much oil, or too low temperature caused. The solution is to sand the advection drop with water.

4 Hardware pollution: operation should be careful, timely clean the pollution. Hardware as far as possible after the installation of paint, paint before the hardware installation of the hole drilling good.
