Problems solved by technology

However, due to the high price of the anti-roll plate and the long waiting time for the goods, most units have to make do with it or simply give up using it. It is very troublesome to splice the film directly by hand to prevent the film from curling, and it also affects the quality of the slice.

Embodiment 1

[0016] A method for repairing a glass anti-roll plate of a cryostat, comprising the following steps:

[0017] (1) After removing the glass anti-roll plate, immerse it in an organic solvent, and use ultrasonic cleaning for 25 minutes. After taking it out, first clean the surface with ethanol solution, and then rinse it with clean water;

[0018] (2) Put the glass anti-roll plate treated in step (1) into an oven at 75°C. After drying for 70 minutes, immediately drop the treatment liquid on the damaged part of the glass anti-roll plate. The treatment liquid is treated for 10 minutes. The solution is made of the following components by weight: 14 parts of hydrofluoric acid, 2 parts of sodium molybdate dihydrate, 1 part of sodium methacrylate, and 290 parts of water;

[0019] (3) Clean the surface of the glass anti-roll plate treated in step (2) with ethanol solution, then put the whetstone into the modifying solution, soak it for 50 minutes, and slowly clean the surface of the gla...

Abstract

The invention discloses a method for repairing the anti-furling glass plate of a freezing microtome. The method comprises the following steps: (1) taking down the anti-furling glass plate, immersing the anti-furling glass plate in an organic solvent, ultrasonically cleaning the anti-furling glass plate, taking out the anti-furling glass plate, cleaning the surface of the anti-furling glass plate with an ethanol solution, and flushing the anti-furling glass plate with clear water; (2) placing the treated anti-furling glass plate obtained in step (1) in an oven, drying the treated anti-furling glass plate, immediately dropwise adding a treatment fluid to the damaged part of the anti-furling glass plate, and carrying out treatment fluid treatment; and (3) cleaning the surface of the treated anti-furling glass plate obtained in step (2) with the ethanol solution, placing an oilstone in a modifying solution to carry out immersion treatment, slowly rubbing down the damaged part of the anti-furling glass plate by using the oilstone, and cleaning the anti-furling glass plate with water to complete the repairing. The method for repairing the anti-furling glass plate of the freezing microtome can effectively repair coarseness and saw marks on the anti-furling glass plate and avoid resource wastes caused by discarding of the damaged anti-furling glass plate.

Description

technical field [0001] The invention belongs to the technical field of cryostat maintenance, and in particular relates to a method for repairing a glass anti-roll plate of a cryostat. Background technique [0002] At present, most cryostats are equipped with anti-roll plates. As long as they are adjusted properly, they can ensure the flatness of the frozen sections and make the slicing process more convenient and fast. However, after a period of use, the glass edge of the anti-roll plate will be damaged and rough, and the surface of the slice will be scratched and produce knife marks. At this time, the anti-roll plate must be replaced. However, due to the high price of the anti-roll plate and the long waiting time for delivery, most units have to make do with it or simply give up using it, and directly splice the sheets by hand to prevent the sheets from curling, which is very troublesome and affects the quality of the slices. Contents of the invention [0003] In order ...
