试验用的侵蚀介质是化学纯。将待测中碱玻璃纤维的受蚀部位埋在氢氧化物粉剂里,并放在恒温恒湿箱内,经同一温度、不同湿度、不同时间侵蚀后进行测试。并对多种水泥浆液在同一温度、不同时间对中碱玻璃纤维的受蚀情况进行测试,所得结论如下: 1.氢氧化物对中碱玻璃纤维的侵蚀与其pH值有直接关系。pH值越高,对中碱玻璃纤维的侵蚀越严重。因此,pH值为14的KOH和NaOH对中碱玻纤的侵蚀最严重;
The aggressive medium used for the test is chemically pure. Will be tested in alkali glass fiber parts buried in hydroxide powder, and placed in a constant temperature and humidity box, the same temperature, humidity, erosion time after the test. And a variety of cement slurry at the same temperature, at different times on the erosion of the medium-alkali glass fiber, the conclusions are as follows: 1. The alkali hydroxide on the erosion of alkali glass fiber and its pH value is directly related. The higher the pH, the more severe the attack on the alkali glass fiber. Therefore, KOH and NaOH with pH value of 14 have the most serious erosion to the alkali glass fiber;
