    密封固化地坪完工后如何判断其好坏

    1、测试硬度好的重庆混凝土密封固化剂使用到地面之后,反应迅速,因为混凝土密封固化剂本来就是一种化学材料能使水泥地面变硬,所以,使用混凝土密封固化剂后,用硬币划,不会出现痕迹。而正常的水泥地面用硬币划是会有痕迹出现的。

    1. When the concrete sealant with good hardness is used on the ground, the reaction is quick. Because the concrete sealant is a kind of chemical material which can harden the cement ground, so when the concrete sealant is used, there will be no trace. The normal cement floor will be marked with coins.

    2、好的重庆混凝土密封固化剂是具备一定的渗透能力的,它们使用在混凝土表面时,会慢慢渗透下去,与混凝土发生化学反应,产生一种不膨胀不收缩化学性能稳定的水合硅酸钙,从而得到一个无尘、致密的整体。相对差的混凝土密封固化剂只是在水泥表面,形成一个保护膜,但实际上并没有完全渗透到混凝土里面,这样的结果就是仅仅维持表面现象,一段时间之后这些膜会被磨损,原来的水泥地面还是水泥地面。

    2. Good Chongqing concrete sealants and solidifiers have certain permeability. When they are used on the concrete surface, they will gradually penetrate into the concrete and react with the concrete to produce a kind of hydrated calcium silicate with stable chemical stability and no expansion and no shrinkage, so as to obtain a dust-free and compact whole. Relatively poor concrete sealants only form a protective film on the cement surface, but do not actually penetrate into the concrete completely. The result is that only the surface phenomenon is maintained. After a period of time, the film will be worn away, and the original cement floor is still the cement floor.

    3、施工完,滴水在表面测试:水成珠越圆越饱满的,说明密封性越好,不易成珠的,易分散的,不饱满的,说明密封性较差。测试亮度和透明结晶层,在不施工光亮剂的前提下,化学反应形成的晶体越多,越紧密。他反射光线越均匀,越多,用眼睛观看亮度会越好。好材料因形成的晶体多,施工完能看到很薄的透明结晶层,差的则很少或没有,所以亮度和透明结晶层也是材料好坏的指标之一。

    3. After construction, the drip is tested on the surface: the more round the water beads, the fuller, indicating that the better the sealing, not easy to bead, easy to disperse, not full, indicating that the sealing is poor. Test the brightness and transparency of the crystalline layer, without the application of brighteners, the more crystals formed by chemical reaction, the closer. The more homogeneous he reflects the light, the better the brightness will be with his eyes. Good materials can see very thin transparent crystalline layer after construction because of the formation of many crystals, and poor ones are few or no, so brightness and transparent crystalline layer is also one of the indicators of material quality.

    判断密封固化环氧地坪好坏容易出现几个误区:

    There are several misconceptions about sealing and curing floors.

    1、以是否有手滑感来判断,“手滑感”,实际上大部分碱性溶液,都侵蚀人的皮肤,而产生手滑的感觉,如起蜡水、肥皂水、碱性的混凝土密封固化剂,但市面酸性的混凝土密封固化剂的材料,就没有这种感觉。手滑感只是碱性溶液的一个共同特点,而不能以次来判断材料的好坏。

    1. To judge whether there is a slippery sense of hand, "slippery feeling", in fact, most of the alkaline solution, erosion of human skin, and produce a slippery feeling of hand, such as wax, soapy water, alkaline concrete sealant curing agent, but the market of acidic concrete sealant materials, there is no such feeling. Hand slip is only a common characteristic of alkaline solution, and can not be used to judge the quality of material.

    2、以是否冒泡来判断实际上混凝土中的毛孔中,存有一定的空气,渗透的快的,稀的溶液。置换毛孔中的空气就快,空气快速排出,就有冒泡现象。相反渗透的慢的,稠的溶液,空气排出慢。可能冒泡现象就少或没有。所以冒泡只是空气排出的一种现象,而不能以次来判断材料的好坏。

    2. To determine whether bubbles actually exist in the pores of concrete, there is a certain amount of air, permeable fast, dilute solution. Replacement of pores in the air is fast, the rapid discharge of air, there is bubbling phenomenon. In contrast, the slow, thick solution of permeation slows down the air. There may be little or no bubbling. So bubbling is just a phenomenon of air drained, and we can not judge the quality of material by the second.

    3、酸性的材料会和碱性的混凝土起中和反应,所以碱性的材料好于酸性的材料。实际上市面上的材料,不管酸性的、碱性的,都是和混凝土中碱性物质起化学反应,一般都在很短的时间就完成初步反应并形成新的物质。市面上材料碱性的PH值在10-11,酸性的PH值在2-3,都属于强酸性、强碱性,如果不快速起反应,长期浸泡对地面都有腐蚀性,而不只是简单的起中和反应,所以酸性的会和碱性的混凝土起中和反应,碱性的好于酸性的说法是一误区。

    3. The acidic material will react with the alkaline concrete, so the alkaline material is better than the acidic material. In fact, the materials on the market, whether acidic or alkaline, are chemical reactions with the alkaline substances in concrete, generally in a very short time to complete the initial reaction and form new substances. On the market, the pH value of alkaline materials is 10-11, pH value of acidic is 2-3, all belong to strong acidity, strong alkaline, if not react quickly, long-term immersion on the ground have corrosive, not just simple neutralization reaction, so acidic and alkaline concrete will neutralize reaction, alkaline is better than acidic is a mistake Area.
