我厂生产的多孔混凝土砌块是在金属模具内浇注料浆后,经蒸压养护而成,所以必须考虑脱模问题。多年来,采用市售回收杂油和废机油做模具油,虽然脱模效果良好,但用量大,对产品外观的污染还存在一定的问题。仅我厂二车间每月脱模用油达20多吨,同时油的污染还影响到砌块与水泥砂浆的粘结。针对这些情况我们选用油包水型乳化油作模具油,并进行了试验。 The porous concrete block produced by our factory is cast in the metal mold after autoclave curing, so we must consider the issue of mold release. Over the years, the use of commercially available recycling of waste oil and waste oil as mold oil, although the mold release effect is good, but the amount of large, the appearance of the product of pollution there are still some problems. Only the second plant of our factory has released more than 20 tons of oil every month. At the same time, oil pollution has also affected the bonding of the blocks and cement mortar. For these cases, we chose water-in-oil emulsified oil as the mold oil and conducted tests.
