無錫環(huán)氧地坪【咬底】現(xiàn)象是指環(huán)氧地坪漆面漆將底漆涂膜軟化、膨脹，在無錫環(huán)氧地坪表層形成皺紋的現(xiàn)象，一般在施工含有強溶劑環(huán)氧地坪漆材料時容易產(chǎn)生這種現(xiàn)象。環(huán)氧地坪漆出現(xiàn)【咬底】現(xiàn)象主要是兩方面的問題：

Epoxy floor varnish [underbiting] phenomenon refers to the phenomenon that epoxy floor varnish softens and expands the primer film and forms wrinkles on the surface of the floor. Generally, this phenomenon is easy to occur in the construction of floor varnish materials containing strong solvents. There are two main problems in the appearance of epoxy floor paint. 

1、地坪漆材料不配套

1. Unmatched Floor Paint Material

一般來說環(huán)氧地坪漆材料廠家的產(chǎn)品都是配套生產(chǎn)，但不同地坪漆廠家配方不一樣，如果混搭使用，很可能會出現(xiàn)原地坪漆發(fā)軟的問題，而一旦底漆發(fā)軟膨脹，就會出現(xiàn)【咬底】的弊病。所以要求施工同一廠家產(chǎn)品，這樣可以減少風險。如果一定要分用兩家材料，建議先小面積進行試驗，無咬底現(xiàn)象才大面積使用。

Generally speaking, the products of epoxy floor paint material manufacturers are all matched production, but the formulations of different floor paint manufacturers are different, if mixed use, it is likely that the original floor paint will be soft, and once the primer softens and expands, there will be the disadvantage of underbiting. Therefore, the construction of the same manufacturer's products is required, which can reduce the risk. If two materials must be used separately, it is suggested that small areas should be tested before large areas can be used without underbiting.

2、涂層未干透就涂下一道漆

2. Paint a coat before it dries out thoroughly

環(huán)氧地坪漆是固化成膜的油漆涂料，要出現(xiàn)韌性、強度需要完全固化才行。而如果底漆還沒有完全干就施工面漆，底漆和面漆會滲透在一起互相影響，從而導致【咬底】的問題出現(xiàn)?；蛘呤敲嫫崾┕み^厚，干燥時間過長，也會出現(xiàn)【咬底】的問題。

Epoxy floor paint is a film-forming paint, which needs to be completely cured in order to have toughness and strength. If the primer is not completely dry, the primer and the top coat will penetrate into each other, which will lead to the problem of underbiting. Or paint construction is too thick, drying time is too long, there will be a problem of undercutting.

環(huán)氧地坪漆出現(xiàn)【咬底】現(xiàn)象怎么辦?

What about the phenomenon of underbiting of epoxy floor paint?

1、底漆和面漆應配套使用。

1. Primers and topcoats should be used together.

2、底涂層干透后再涂面漆;應在底漆還未完全干透之前罩面漆;在容易產(chǎn)生咬起的配套涂層場合，應先在底涂層上薄薄涂一層面漆，待銷干后再進行面漆的厚涂施工。

2. Primer coatings should be coated after drying. Primer coatings should be covered before drying completely. In the case of matching coatings which are easy to bite, a thin layer of primer coatings should be applied first, and then a thick layer of primer coatings should be applied after the primer is dried.

3、如果出現(xiàn)嚴重咬底的現(xiàn)象，需將涂層全部鏟除干凈，待基層干燥后再選用同一品種的地坪漆材料進行涂刷。

3. If serious underbiting occurs, the coating should be completely eradicated, and the same kind of floor paint material should be selected for painting after the base is dried.
