环氧地坪漆是否可以在起砂的舊地面上

起砂的舊地面一定要打磨，如果原地面標號不夠打磨也沒用，建議再重新水泥澆築，然後做你需要的环氧地坪，环氧地坪材料有多種，可根據你的要求來做，但要聽取工程師的意見，要不然會影響使用年限。环氧地坪工程环氧地坪專傢意見：工地上常常使用界面劑攪拌水泥進行塗刮，希望將起砂部位覆蓋，事實上這樣不會達到預期效果，一般情況幹燥後表層又會龜裂，剝落，大面積起殼。這是由於基層未處理好的原因，基層起粉，想通過覆蓋達到修復的效果是完全錯誤的想法。
The old ground must be sanded, if the original ground label is not enough grinding is useless, it is recommended to RE-cement pouring, and then do the epoxy floor you need, epoxy floor materials can be done according to your requirements, but to listen to the opinions of the engineers, otherwise it will affect the service life. Epoxy floor engineering experts opinion: the site often use interfacial agents to mix cement scraping, hoping to cover the sand part, in fact, this will not achieve the desired effect, generally dry surface will crack, peel off, large area of shelling. This is because the grass-roots has not been properly treated, the grass-roots flour, want to achieve the effect of repair by covering is completely wrong idea. 1.水灰比過大：即拌合的混凝土水量大，導致混凝土表面泌水，降低混凝土表面強度。
1. Water cement ratio is too large: that is, the mixing of concrete water, resulting in the surface of concrete bleeding, reducing the surface strength of concrete.
2.砂石料的級配不合理、含泥量高：骨料級配不合理、過細的土砂也易導致地面起砂，影響水泥的早期水化及混凝土的凝結。
2. The unreasonable gradation of sand and stone and the high content of mud: the unreasonable gradation of aggregate and the excessive fine sand also easily lead to the ground sand, affecting the early hydration of cement and the setting of concrete.
3.施工過程中的過分振搗：加劇混凝土表面的泌水，導致混凝土表面強度較低。
3. Excessive vibration durin环氧地坪g construction: aggravate the bleeding of concrete surface, resulting in low surface strength of concrete.
4.養護不當：未能及時養護或養護不充分，暴曬或大風導致混凝土表面大量失水，表面得不到充分水化，導致強度較低。
4. Improper maintenance: not timely maintenance or inadequate maintenance, exposure to sunlight or wind caused a large number of concrete surface dehydration, surface can not be fully hydrated, resulting in low strength.
5.其它原因：壓光時間掌握的不好、混凝土表面未達到一定的強度就上人作業、低溫下施工混凝土表面受凍等。
5. Other reasons: poor control of calendering time, concrete surface did not reach a certain strength on the work, low tempe印花地坪rature construction of concrete surface frozen, etc.
