日标方矩管JIS-G3466壁厚标准

日标方矩管jis-g3466壁厚标准
日标方管：u－pvc管内壁光滑，阻力小（upvc管阻力系数为.9,而一般的镀锌管.铸铁管阻力系数为.12－.13）,因而水力条件好是显而易见的。当用同样管径的管输送同样液体时，upvc管比镀锌管.铸铁管的阻力小3％左右；当水头损失相同时，upvc管的输水能力比铸铁管大2％以上。由于upvc管内壁光滑，液体在内流动不会结垢，因而其输送能力不会随运行时间的增强而下降。而这一点也正是镀锌管和铸铁管不可克服的缺点。

一般情况下，磷化处理要求工件表面应是洁净的金属表面（二合三合四合一例外）。工件在磷化前必须进行除油脂、锈蚀物、氧化皮以及表面调整等预处理。特别是涂漆前打底用磷化还要求作表面调整，使金属表面具备一定的"活性"，才能获得均匀、细致、密实的磷化膜，达到提高漆膜附着力和耐腐蚀性的要求。磷化前处理是获得高质量磷化膜的基础。酸蚀反应金属表面与磷化液发生的个反应是将某些金属从表面溶解下来的酸蚀反应。
