The antiseptic materials must have strong adhesiveness, good corrosion resistance and good viscosityresistance.
防腐材料应具有附着力强、耐蚀性优良以及抗粘塔能力好的优点。
2
The traffic pressure, viscosity factor and viscosityresistance is proposed. Their physical significance is clear and can be easily to calculate.
提出了物理意义明确、计算简便的交通压力和黏性阻力系数以及黏性阻力。
3
Mainly is the pump speed is too high, medium and high viscosityresistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload;
