Embodiment 1
[0034] This embodiment provides a medical glass bottle with low liquid residue and low liquid residue, the preparation steps of which include:
[0035] S1, adding polystyrene microspheres and dispersant to ethanol to make a 0.2wt% polystyrene microsphere solution; filling the 0.2wt% polystyrene microsphere solution in a medical glass bottle, After standing still for 15min, the 0.2wt% polystyrene microsphere solution was poured out in a medical glass bottle, and the medical glass bottle was heated at 100°C for 15min, as figure 1 and figure 2 As shown, to coat polystyrene microspheres 2 on the inner surface 1 of the medical glass bottle;
[0036] S2, adding organopolysiloxane and dispersant to deionized water to make a 15wt% polysiloxane dispersion solution; filling the 15wt% polysiloxane dispersion solution in a medical glass bottle, statically After standing for 15min, pour out the polysiloxane dispersion solution in a medical glass bottle, such as image 3 As shown, to in...
Embodiment 2
[0039] This embodiment provides a medical glass bottle with low liquid residue, the preparation steps of which include:
[0040] S1, adding polystyrene microspheres and dispersant to ethanol to make a 0.1wt% polystyrene microsphere solution; filling the 0.1wt% polystyrene microsphere solution in a medical glass bottle, After standing still for 20min, pour out the 0.1wt% polystyrene microsphere solution in the medical glass bottle, and heat the medical glass bottle at 150°C for 10min, as figure 1 and figure 2 As shown, to coat polystyrene microspheres 2 on the inner surface 1 of the medical glass bottle;
[0041] S2, adding organopolysiloxane and dispersant to deionized water to make a 20wt% polysiloxane dispersion solution; filling the 20wt% polysiloxane dispersion solution in a medical glass bottle, static After standing for 10min, pour out the polysiloxane dispersion solution in a medical glass bottle, such as image 3 As shown, to infiltrate the polysiloxane into the ga...
