环氧地坪漆施工中塗膜層間附著力差的原因

环氧地坪漆中混凝土固化劑用量過多，使环氧地坪漆漆膜脆硬；催化劑用量不當，使漆膜過脆，或基材除油去塵不徹底，使基材沾污油脂、灰塵等，是產生漆膜附著力差的原因。PU环氧地坪漆施工後，放置時間過長，舊漆未經打磨處理和清潔處理，或底層含矽助劑太多，造成重新塗环氧地坪漆後，漆層間附著力差，甚至出現剝離。
The excessive amount of concrete curing agent in epoxy floor paint makes the film brittle and hard, the improper amount of catalyst makes the film brittle, or the base material is not thoroughly degreased and dedusted, so that the base material is contaminated with grease and dust, which is the reason for the poor adhes印花地坪ion of the paint film. After the construction of PU floor paint, the time of placing is too long, the old paint has not been polished and cleaned, or there are too many silicon additives in the bottom layer, resulting in poor adhesion between coatings and even peeling after re-coating of epoxy floor paint.
要防止环氧地坪漆附著力差和克服漆層間產生剝離現象，必須嚴格控制混凝土固化劑的比例，控制催化劑的用量，對被塗裝的基材要徹底清除油污，對舊的漆膜或擱置時間過長的漆膜，要清潔塗膜表面，並打磨平滑清潔後再塗新的环氧地坪漆。要重塗的漆，要選擇可重塗的助劑（尤其是含矽助劑），並嚴格控制添加量，已形成附著力差的环氧地坪漆漆膜，必須脫除幹凈，重新清潔底材，合理按比例配漆，重新塗裝。
In order to prevent the poor adhesion of epoxy floor paint and overcome the peeling phenomenon between coatings, it is necessary to strictly control the proportion of concrete curing agent, control the amount of catalyst, thoroughly remove the grease stain on the coated base material, clean the surface of the old coatings or coatings that have been put on shelf for too long, and polish the surface of the coatings smoothly and then coat it again. New epoxy floor paint. In order to re-coat the paint, it is necessary to select re-coatable auxiliaries (especially silicon-containing auxiliaries) and strictly control the amount of additives. The epo透水地坪xy floor paint film with poor adhesion has been formed. It is necessary to remove it, re-clean the base material, properly mix the paint in proportion and re-coat it.
