The corrosion protection practice showed that the tubes with protective coating of nano titaniumpolymer and alloy tubes with tungsten-plating performed well in the corrosive environment.
实践表明,“钛纳米聚合物防腐蚀涂层油管”和“镀钨合金防腐蚀油管”在上述环境使用较为适合;
2
The catalysts comprise a vinylpyridine polymer and a titanium zeolite.
催化剂包括乙烯基吡啶聚合物和钛沸石。
3
Preferably, the vinylpyridine polymer encapsulates the titanium zeolite.
