环氧地坪適用各種區域,比如電子廠房、醫院、化學工廠、服裝廠、倉庫等地方。提醒正在施工环氧地坪的朋友註意瞭,一定要註意以下幾點,讓大傢預防环氧地坪開裂。缺陷狀況:1.环氧地坪細裂:塗膜塗裝後產生肉眼不易辨認,但用十倍顯微鏡可明顯觀察到的細紋。它是由塗裝內部的收縮力超過塗膜本身內聚力而引起塗膜表面的破裂。它無損於塗膜的美觀,是塗膜老化的必然結果。但如果在塗裝後不久就出現此種情況,那就是一種病態。
Epoxy floor is suitable for various areas, such as electronic factory, hospital, chemical factory, garment factory, warehouse and so on. Reminds the friends who are constructing the epoxy floor to pay attention to, must pay attention to the following points, lets everybody prevent the epoxy floor cracking. Defects: 1. Fine cracks in epoxy 彩色沥清地坪floors: Fi环氧地坪ne lines can be observed with a ten-fold microscope, though they are not easily recognized by the naked eye after coating. It is caused by the internal force of the coating which exceeds the cohesion of the film itself and causes the rupture of the coating surface. It does not damage the appearance of the film, and is the inevitable result of the aging of the film. But if this happens soon after painting, it is a pathological condition. 2.环氧地坪粗裂:塗膜在塗裝後不久產生明顯粗裂紋,有時可見底的現象。
2. epoxy floor crack: the coating will produce obvious cracks shortly after coating, and sometimes the bottom phenomenon can be seen.
3.环氧环氧地坪龜裂:塗膜在塗裝後出現形狀類似龜背上紋路裂紋的現象。鱷魚皮裂紋和玻璃裂紋也有此類似現象。
3. epoxy floor cracks: the coating appears after the painting is similar to the phenomenon of cracks on the back of the turtle. Crocodile skin cracks and glass cracks also have similar phenomena.
环氧环氧地坪開裂原因:
Causes of cracking on epoxy floor:
1.塗膜幹燥後,硬度過高,而柔韌性又較差,如用含有共雙鍵的脂肪酸或它的酯所配制的塗料;
1. Coatings with high hardness and poor flexibility after drying, such as coatings made from fatty acids or esters containing co-double bonds;
2.頭道漆沒幹透就塗二道漆,兩層塗膜內外伸縮力不一致;
2. the first coat of paint is not dry enough to be painted with two lacquers, and the two layers of coating have different internal and external expansion forces.
3.塗層配套不適當,例如底漆層比面漆層塗膜軟;
3. the coating is not suitable, for example, the primer layer is more flexible than the topcoat coating.
4.环氧地坪面漆中揮發組分太多,影響成膜的結合力而引起塗膜幹裂;
4. there are too many volatile components in epoxy floor coatings, which affect the bonding force of film forming and cause the film to dry crack.
5.塗層過厚,表層幹而內層沒有幹透;
5. the coating is too thick, the surface layer is dry and the inner layer is not dried.
6.催幹劑用量過多或各種催幹劑搭配不當;
6. excessive dosage of drier or improper matching of various driers.
7.塗膜在有污氣(如二氧化硫、氨氣等)的环境下應用;
7. coating is applied in polluted environment such as sulfur dioxide and ammonia.
8.色漆在使用前未攪勻,上層樹脂多顏料少,而下層顏料多樹脂少,塗裝後容易開裂;
8. The paint is not stirred before use, the upper resin has more pigments and less, while the lower paint has more pigments and less resins, so it is easy to crack after painting.
9.塗層耐候性或耐溫變性不佳
9. the weatherability or temperature resistance of the coating is poor.
