(4)routine operation (boiling 1% sodium bicarbonate solution) added ultrasonic washing with clean water and baking procedure. Washing quality of four kinds of methods mentioned above had been compared.
And then each kind of the negative effects on washing for the washing mode is also analyzed in details. At last, the paper points out the reasons why the washing efficiency is lower and the washing quality is worse than other type machines. The research work provides a firm theoretical base for improving the washing machine design.
The paper analyzes the difficulties in washing cathode copper and introduces the research work and its substantial results using dynamic spray washing technology to improve cathode copper washing quality in the development of large size cathode copper machine set.
Conclusion: Cleaning of contaminated medical instruments by effective washing and disinfection with automatic washing machine,coupled with manual washing and brushing and treatment with enzymatic detergent and heating,can ensure the washing quality.
The test results based upon detergent concentration 0.2 g/L as specified in the National Standard showed there is deficiency in aspect of data accuracy and repeatability.
Results Quality management was improved and nursing management was also improved. The qualified rate of washing achieved 98.8%, the qualified rate of packing group was 99.2%, and the qualified rate of sterilization was 100%.
Through optimizing the reflux ratio of the fractionation column and improvement of discharge operation of the scrubbing process, the scrubbing effect is much better than before, the time of scrubbing is decreased to a great extent and the output of crude phenol is increased greatly.
It was reported that management experiences of quality control for disinfection supply rooms in hospital.It was base on situations of management,moritoring etc.,which were belong in disinfection supply rooms of 63 hospital in Chengdu city.
To raise washing quality of dry cleaning agent,adding proper surfactant and a little of water in commercial dry cleaning agent is an important method in order to improve cleaning rate.This paper discusses the principle of detergency and effects of surfactant and water in the dry cleaning agent.Wool fabric with simulatc nature filth is washed in normal way to find the best composition in more than 20 kinds of surfactant.The experiment proves that adding suitable oil soluble surfactant and a little wate...
