The products made by my factory have for many times been regarded as the first - grade products by the authoritative departments , and are sold well over more than 20 provinces , cities and autonomous regions , warmly welcomed by the vast customers 我厂生产产品经多次权威部门检测均为一等品，产品销往全国20多个省市自治区，深受用户欢迎。
However , the waterproof function and anti - fungus capability of ccf is relatively so poor that the quantity of first - grade and excellent - quality products is very few . in addition , the external antifriction layer of ccf is expensive and faulty , and 80 % of manufactories in china depend on the import antifriction paper . aimed at the situation , this paper put forward a simple and effective way - rabbet surface sealing technique ( rsst ) to improve the waterproof function and anti - fungus capability of ccf 本文针对其防水抗霉性能较差、一等品及优等品极少；以及其表层耐磨纸价格昂贵、缺陷较多，尤其我国生产厂家80依赖进口耐磨纸的现状，提出一种简便而行之有效的方法? ?企口表面全封闭法来改善复合强化地板的防水抗霉性能，并采用国产材料研制出一种集装饰功能与高耐磨性能于一体、生产成本很低的新型高耐磨层，以替代进口耐磨纸。
The main technical conditions for preparing activated clay with bentonite were determined . the decolored rate and activated degree of the product were increased by processing bentonite ore . the high quality activated clay was prepared successfully . moreover , the factors affecting the quality of product were also discussed 本文以安徽某地膨润土为原料，首先对其分级提纯，然后对影响活性白土质量的主要工艺条件进行较为系统的试验研究，成功地制备了脱色力大于200 ，且脱色率、活性度均超过国家化工行业规定的一等品标准的高效活性白土。
The coatings are tested comply with the requirements of national standards gb / t 9756 - 2001 , the synthesis performance exceed the index of first - rank production , in the same time the average antibacterial rate of these inorganic materials can reach 90 percent . when the weight amount of the inorganic antibacterial powder of ag + and ce2 + reaches 2 percent , the antibacterial rate of the coating is 99 . 976 percent 通过检测发现，样品性能完全符合并超过合成树脂乳液内墙涂料标准中对一等品的要求，同时抗菌效果可达到90 . 0以上，当多孔纳米sio _ 2载银、铈材料在涂料中的添加量为2 ( wt )时，改性涂料的抗菌率可达到99 . 976 。
