We have done following test for the performance that detects this releasing agent:
Still do not have at home under the touchstone situation of evaluation demolding performace, we are with the adhesive power of butt sand-cement slurry cone to template, and the ash amount of being stained with of the void content on knock-outs will surface, template etc. is measured its performance.
Butt sand-cement slurry cone to the measuring method of the adhesive power of template is: truncated cone, and bottom surface diameter and height are respectively 10cm, and the end face diameter is 6cm, and demoulding lifting suspension ring are equipped with on the top.During mensuration, releasing agent is applied on 15 * 15 centimetres the metal sheet, cone is put thereon, make it be shaped to the sand-cement slurry cone, under 20 ℃ of temperature, placed 24 hours again, measure the remove power of sand-cement slurry cone to metal form with ergometer, and compare with other product (W-15 of Wuhan chemical industry two factories, the RH of Wanrong, Shanxi), it the results are shown in table 1.
In the concrete member cast, often occur more hole bubble on the molding surface, be commonly called as pitted skin.The generation of these hole bubbles, be owing to the state of interface of holding back bubble, the event of bubble, release agent coating on template, the concrete interface is one of reason that directly influences the formation of surface holes bubble, therefore measure the surface holes bubble rate of stripping surface, can evaluate the quality of releasing agent.We measure with reference to the method for U.S.'s cement and the proposition of concrete association.The method of taking is: in selected areal extent, measure hole bubble number and hole bulb diameter earlier, calculate the area occupation ratio of portal bubble area and hole bubble again.The concrete practice is: the metal test mould moulding concrete thin plates that will scribble 20 * 20 * 4cm of releasing agent, number and diameter are steeped in the above hole of observation concrete plate surface 2mm after treating the demoulding, the calculating bubble rate of portalling, and take by weighing the adherent mortar amount of template surface, its test comparing result sees Table 1:
As seen from Table 1, the measured quantity and the machine oil of this releasing agent adhesive power are close, and is littler than other releasing agent, and visible stripping result is good, and the lubrication drag reduction performance is good, thereby also prevent or reduced the formation of concrete surface hole bubble.The sticking ash amount of template surface is also lacked than other releasing agents.
As everyone knows, Highrise buildings need use a large amount of facades and lateral punching block, and the sticking ash of these templates is many, and demoulding difficulty is big, therefore needs to adopt the good releasing agent of demoulding usefulness.The Nanjing that one smelting brickwork company undertakes the construction of is won the sight hi-line completely and is crossed Jiang Ta, 248 meters of tower heights, and the housing structure complexity, external mold adopts and goes straight up to template, and internal mold is a turn-over form, and difficulty of construction is big.One smelting brickwork company adopts this releasing agent, has made the relevant dose that is coated with, and release times, template are stained with the test of aspects such as ash amount.Test method is: select 4 0.5 * 0.2 meter coarse Sheet Steel Form that has no smooth finish for use, be spliced into vertical cubes, 0.4 meter of demoulding area
2, behind the brushing releasing agent, deposit concrete, the demoulding again, its test result sees Table 2.
