    如何解决环氧地坪制品发黄的问题

    环氧地坪认为:有用的处理方法即是增加抗氧剂与紫外线吸收剂,可有用地避免与推迟发作黄变。但是抗氧剂的品种繁复,从中挑选合用的商品,需求必定的技术支持与经历堆集。参看:环氧地坪技术研究。 挑选有用的环氧地坪抗氧化剂 抗氧剂的分类,一种是主抗氧剂:捕获过氧化自由基,主要是受阻酚抗氧剂;一种是辅佐抗氧剂:分解氢过氧化物,主要是亚磷酸酯类、硫代酯类。通常情况下,根据各个厂家的出产工艺及质料、溶剂、助剂、填料,哪个期间的黄变,黄变程度的不一样,而主张运用不一样的抗氧剂。

    Epoxy flooring is considered to be a useful treatment method, that is, adding antioxidants and ultraviolet absorbents, which can effectively avoid and delay the onset of yellowing. But the variety of antioxidants is complex, from which to select suitable commodities, the need for technical support and experience is bound to pile up. See: Floor technology research. Select useful antioxidants for epoxy flooring. One is the main antioxidant: capturing peroxide free radicals, mainly hindered phenol antioxidants; the other is the auxiliary antioxidant: decomposing hydrogen peroxide, mainly phosphite esters and thioester. Usually, according to the production process and materials, solvents, additives, fillers, which period of yellowing, yellowing degree is different, and advocate the use of different antioxidants. 选用合适的环氧地坪紫外线吸收剂

    Selection of suitable ultraviolet absorbent for epoxy flooring

    本来形成环氧体系氧化黄变的重要元凶还有紫外线,来历主要是太阳光,因此,特别是在面对出产出来的商品需求在户外运用的客户,咱们都会引荐在商品中增加必定量的紫外线吸收剂,能有用地吸收紫外线,推迟黄变。而且,紫外线吸收剂与抗氧剂一同运用,能起到一个协同效应,起到1加1大于2的作用。 姑苏环氧地坪工程事例赏析 本来,抗氧剂与紫外线吸收剂的运用并不能从根本上处理环氧地坪黄变疑问,但是在必定的规模和必定的时间内,仍是能有用地避免商品氧化黄变,坚持商品水色通明,进步环氧地坪商品的层次。

    Ultraviolet radiation is also the main culprit of oxidative yellowing of epoxy system. Its origin is mainly sunlight. Therefore, especially for the customers who need to use the products outdoors, we will recommend adding certain amount of ultraviolet absorbent in the products, which can effectively absorb ultraviolet radiation and delay yellowing. Moreover, the use of ultraviolet absorbers together with antioxidants can play a synergistic effect, playing the role of 1 plus 1 over 2. Appreciation of Gusu epoxy flooring project case originally, the application of antioxidants and ultraviolet absorbents can not fundamentally solve the problem of yellowing of epoxy flooring, but in a certain scale and time, it is still useful to avoid oxidative yellowing of commodities, adhere to the bright color of commodities, and improve the level of commodities on the flooring.
