Performance detection experiment: the o-phthalein gray scale stain release paste was prepared as in examples 1-8 and then tested according to the QB/T2117-95 performance specifications to give the following Table 1 results:
table 1 Performance index of the o-Bunge ash-stain-removal pastes of examples 1-8
As can be seen from Table 1, the cleaning pastes prepared by the method meet the performance index requirements of the general water-based metal cleaning agent on QB/T2117-95.
And (3) testing the o-benzene grey dyeing removal rate: according to the detection method in QB/T2117-95, preparing a stainless steel sheet, and manually spraying the stainless steel sheet by using the phthalic full disinfectant until the surface of the stainless steel is obviously grey, so as to prepare the grey-dyed stainless steel surface.
The application method of the grey dye decontamination paste comprises the following steps:
a proper amount of the product is coated on the surface of an object with grey dyeing phenomenon to be removed, and the product is required to stay on the surface of the object for 5-10min at the position with serious pollution phenomenon;
wiping the surface of the grey object with the wet scouring pad;
wiping and scrubbing the mixture with a clean brush under flowing deionized water.
Detecting the ash stain removal rate of the o-benzene ash stain removal paste; the removal rates of examples 1 to 8 were 98.0%, 98.8%, 99.9%, 99.5%, 98.7%, 98.3%, 98.7% and 98.2%, respectively. The removal rates of comparative examples 1 to 8 were 69.6%, 78.3%, 72.3%, 63.4%, 65.8%, 85.6%, 91.2%, 98.8%, respectively.
As can be seen from the detection data of examples 1-8 and comparative examples 1-8, the removal rate of the o-phthalein grey dye decontamination paste prepared by the method for removing the o-phthalein grey dye phenomenon is up to 98.0%, and the removal rate of the decontamination paste product prepared by optimizing the formula is up to 99.9%, which clearly shows that the o-phthalein grey dye decontamination paste of the method for removing the o-phthalein grey dye phenomenon is high-efficient.
As can be seen from the combination of examples 1-8 and comparative examples 1-8, the o-phthalaldehyde disinfectant disclosed herein employs PRAEPAGEN HY, anionic surfactant, nonionic surfactant and friction agent as the main cleaning agents, and can be used for removing grey stains caused by the o-phthalaldehyde disinfectant through a physicochemical reaction. The selected wetting agent can also play a role in wetting and protecting the surface of the medical instrument, and can further break down the damage caused by grey dyeing to the medical instrument. As can be seen from comparative examples 3 and 8, the addition of the chelating agent has little effect on the removal rate of the gray scale paste, but the chelating agent selected for addition can have a certain adsorption and chelation effect on metal ions, and can further protect medical instruments later. The decontaminating paste has stable paste property, good paste fluidity, mildness, no stimulation and good moisture retention, not only can effectively remove grey stains on medical instruments, but also can form a layer of moisture retention protective film on the surfaces of the medical instruments.
