廠傢分享环氧地坪漆施工之底漆施工技巧
底塗,是环氧地坪漆施工工藝中最重要的一步,隻有這一步做好瞭,才能夠繼續在基面上面進行下一步塗裝。所以,一般對用於环氧地坪塗裝的底漆的要求為:應與基材有良好的附著力;本身具有良好的機械強度;對底材具有良好的保護性能和不起不利的副作用;能為以後的塗層創造良好的基礎,不能含有滲入上層塗膜引起弊病的組分;更要具有良好的施工性和幹燥性。塗佈底漆時一般應註意要在表面處理以後嚴格按照規定的時間及時塗佈底漆。還要根據底漆品種規定的條件在底漆幹燥後規定的時間范圍內塗下一道漆。過早塗佈可能引起咬底及底漆中溶劑揮發困難導致漆膜幹燥時間延長‘固化不良、鼓泡等情況;塗佈達遲可能引起層間附著不良,且過遲塗佈易由於粉塵積累或其他污染影響表觀質量。為增加下一道塗層與底漆間的附著力,可在塗佈前將底漆打磨。
Primer is the most important step in the construction process of epoxy floor paint. Only when this step is completed, can the next step be continued on the base surface. Therefore, the general requirements for primers used for floor coating are: good adhesion with the base material; good mechanical strength; good protective performance and no adverse side effects on the base material; good foundation for future coatings, can not contain the components that cause defects by infiltrating into the upper coating film; and better workability and dryness. When applying primer, attention should be paid to the timely application of primer after surface treatment in strict accordance with the stipulated time. It is also necessary to apply a paint within the specified time range after the primer is dried according to the conditions prescribed by the primer varieties. Early coating may lead to underbiting and difficulty in solvent evaporation in primer, which may lead to prolonged drying time of paint film, such as poor curing, bubbling, etc. Late coating may lead to poor adhesion between layers, and late coating may easily affect the apparent quality due to dust accumulation or other pollution. In order to increase the adhesion between the next coating and the primer, the primer can be polished before coating.
塗佈底漆的方法一般可采用輥塗、刷塗和噴塗。刷塗施工效率較低,一般在邊角處施工采用。最常用的是輥塗,效率高。
Roller coating, brushing and spraying are commonly used for primer coating. Brushing construction efficiency is low, generally in the corner construction. The most commonly used is roll coating, high efficiency. 封閉底漆施工:
Closed primer construction:
用刷塗、輥塗或噴塗的方法施工封閉环氧地坪漆底漆一道至兩道,兩道之間的間隔時間在8h以上,但不能大於48h。對於舊地面,應增加一道底漆。底漆施工時應註意塗佈均勻,塗膜無明顯的厚度差異,防止漏塗。用輥塗法施工應註意餘料堆積情況。底漆封閉不完全(漏塗)時,會發生附著不牢、塗膜起泡等現象。
Brush, roll or spray method is used to construct one or two primers for closed floor paint. The interval between the two primers is more than 8 hours, but not more than 48 hours. For the old ground, a primer should be added. During primer construction, attention should be paid to uniform coating, no obvious thickness difference of coating film, to prevent leakage of coating. Pay attention to the accumulation of surplus materials in roller coating construction. When the primer is incompletely sealed (missing coating), there will be some phenomena such as weak adhesion and blistering of the coating film.
1.底漆漆膜厚度根據底漆品種確定,應註意控制。表面無浮塵及松散砂粒。
1. The thickness of primer film is determined according to the type of primer. Attention should be paid to its control. There is no floating dust and loose sand on the surface.
2.含顏填料的底漆在使用前和使用過程應註意攪拌均勻
2. The primer containing pigments and fillers should be stirred evenly before use and during use.
3.註意遵守幹燥的規范。在底塗上如塗含有強溶劑的塗料時,底漆必須幹透,以免出現咬底等漆病。
3. Pay attention to the standard of drying. When the primer is coated with paint containing strong solvents, the primer must be thoroughly dried to avoid primer biting and other paint diseases.
4.增加下一道塗層與底漆間的附力,可在塗佈前將底漆打磨。
4. To increase the adhesion between the next coating and the primer, the primer can be polished before coating.
5.要在漆前表面處理以後嚴格按照規定的時間及時塗佈底漆。還要根據底漆品種規定的條件在底漆幹燥後規定時間范圍內塗下一道漆。過早塗佈可能引起咬底及底漆中溶劑揮發困難導致漆膜幹燥時間延長、固化不良的情況;塗佈過遲可能引起層間附著不良,且過遲塗佈易由於粉塵積累或其他污染影響表觀。
5. Primer should be coated in time after surface treatment. Also, according to the conditions specified by the primer varieties, a coat should be applied within the prescribed time range after the primer is dried. Early coating may lead to underbiting and difficulty in volatilization of solvents in primers, which may lead to prolonged drying time and poor curing of the film; late coating may lead to poor adhesion between layers, and late coating may easily affect the appearance due to dust accumulation or other pollution.
底漆稀釋按照說明書和环氧樹脂地坪漆施工需要進行,控制好比例,嚴禁過量稀釋。
Primer dilution shall be in accordance with the instructions and the construction requirements of epoxy floor paint, and the proportion shall be well controlled, and excessive dilution shall be strictly prohibited.
須在基面充分幹燥、無異物的情況下進行,對地面必須進行清掃處理,對不符合要求的地面應及時向項目經理反映。
It should be carried out under the condition that the foundation is fully dry and free of foreign matter, and the ground must be cleaned up. The ground that does not meet the requirements should be reported to the project manager in time.
环氧樹脂地坪漆材料開桶後,應充分攪拌均勻再進行使用。
After opening the barrel, the epoxy floor paint material should be fully stirred and evenly used.
先刷邊角及不易棍塗的部位,再由上往下進行大面積施工,不易吸料的地坪用毛刷點刷环印花地坪氧樹脂地坪漆底塗。
First brush the corners and the parts which are not easy to stick, then carry out large-scale construction from top to bottom, and brush the epoxy floor paint primer with a brush on the floor which is not easy to absorb materials.
塗刷時,桶內必須設置滾板,棍筒和毛刷蘸料後必須在滾板上舔料後方可進行施工。
When painting, the barrel must be equipped with rollers, and the barrel and brush dipping materials must be licked on the rollers before construction can be carried out.
若有毛刷毛或棍筒毛沾在墻上,應及時處理。
If there is brush or stick hair on the wall, it should be dealt with in time.
由於溶劑揮發較快,若施工過程中底塗變稠影響施工,可適量添加溶劑,不過一般情況下,不建議采取這種辦法。
Due to the rapid volatilization of solvents, if the bottom coating becomes thicker in the construction process, the solvents can be added appropriately, but in general, this method is not recommended.
檢查地面是否有漏塗現象並加以修補。
Check the ground for leakage and repair it.
重塗時間一般大於6-8小時。
Repainting time is usually more than 6-8 hours.
环氧地坪漆施工效果塗佈率滿足要求;不允許有漏塗現象和流墜、明顯的接搓,做到棍塗均勻。若實際塗佈率與該塗佈率相差較大,應報請項目經理。
The coating rate of epoxy floor paint meets the requirement of construction effect, and no leakage, drop and obvious rubbing are allowed to make the stick coating uniform. If there is a big difference between the actual coating rate and the coating rate, the project manager should be informed.
环氧樹脂地坪漆施工的步驟中,底塗是至關重要的一點,隻有將基面封閉好瞭,才能夠進行下一步塗裝,如果底塗沒有做好,就算後面的工藝做得再好,都將功虧一簣。
In the process of epoxy floor paint construction, the primer is the most important point. Only when the base is sealed, can the next painting be carried out. If the primer is not done well, even if the later process is don透水地坪e well, it will lose a lot.
其他方面要註意的:
Other aspects should be noted:
膩子修補:
Putty Repair:
對水泥基層存在的凹坑,用商品环氧膩子或用底漆和細石英砂配置的环氧砂漿填平,在固化成膜後打磨平整。
The pits in cement base are filled with commercial epoxy putty or epoxy mortar with primer and fine quartz sand, and polished flat after solidification.
中層塗料施工:
Medium coating construction:
對於厚膜型塗料,中層塗料施工時可采用鏝刀鏝塗。由於塗料中使用的石英砂較多,一般情況下刮塗後塗膜不會出現明顯刮刀痕跡,但如果石英砂加入量過大,刮痕明顯時應輥壓一次。塗裝間隔如果大於48h,應進行打磨後再進行下道塗料的施工,以保證層間黏結力。
For thick film coatings, the medium coatings can be applied with trowel. Due to the use of more quartz sand in coatings, there will be no obvious scraper marks on the coatings after scratching, but if the amount of quartz sand is too large, the scratch should be rolled once. If the coating interval is more than 48 hours, the next coatings should be polished to ensure the interlayer cohesion.
面塗料施工:
Surface coating construction:
根據环氧耐磨地坪塗料的種類,面塗料可以采用刷塗或刮塗施工。對於厚膜型塗料,按配比要求將兩組份塗料混合均勻,待熟化後使用1mm刮板刮塗塗料。刮塗時應盡量保持厚膜均勻,無漏塗現象,無明顯餘料。刮塗時,刮刀的移動速度應均勻,刮刀與地面平面夾角為30°左右,以保證塗膜厚度。刮塗道數根據厚度要求而定。普通环氧塗料則可以采取刷塗方法施工。面塗料施工時兩道之間的間隔時間應在18h以上,但不能大於48h。配置好的塗料應盡快用完,以防止塗料的黏度升高,塗料中的氣泡難於排出。
According to the types of epoxy wear-resistant floor coatings, surface coatings can be applied by brushing or scraping. For thick film coatings, mix the two components evenly according to the proportion requirement, and then use 1 mm scraper to scrape the coatings after ripening. When scraping, we should try our best to keep the thick film uniform, no leakage and no obvious surplus. When scraping, the moving speed of the scraper should be uniform, and the angle between the scraper and the ground plane should be about 30 degrees, so as to ensure the film thickness. The number of scraping paths depends on the thickness requirement. Ordinary epoxy coatings can be applied by brushing method. The interval between the two coatings should be more than 18 hours, but not more than 48 hours. The coatings should be used up as soon as possible to prevent the increase of the viscosity of the coatings and the difficulty of discharging the bubbles in the coatings.
环氧地坪養護:
Epoxy Floor Maintenance:
面塗料施工完,並完全固化後,一般應在面塗料施工24h以上方可上人,72小時後方可重壓。(25℃為準,低溫開放時間需適度延長。)
After the surface coating is finished and solidified completely, it should be applied for more than 24 hours before it can be applied, and then it can be re-pressed after 72 hours. (The opening time at low temperature should be prolonged moderately, whichever temperature is 25 C.)
