8. Spray primer for 3-4 times.
9./kloc-After 0/2 hours, spray the surface glaze for 4-5 times. It can't be used within 24 hours, and the hardness reaches the standard in 7- 10 days.
Expand small knowledge:
1. Can the cracked ceramic cup still be used?
It is not recommended to continue using the ceramic cup after it is cracked.
Cracks in ceramic cups are generally caused by uneven heating inside and outside the ceramics, which is equivalent to opening the ceramic cups. Although it does not affect the use, there is a risk of further cracking or even damage, which affects the safety of use. In addition, if there are cracks in the ceramic cup, bacteria may hide in the cracks in the glaze, and it is not good for your health to use this cup again. Therefore, if there is a crack in the ceramic cup, it is recommended not to continue using it in principle. If you are frugal, the cracks can be repaired before you continue to use them.
Second, how to repair the broken ceramic cup?
Cracked ceramic cups are relatively simple to repair. If the ceramic cup is broken, the repair method is more troublesome.
1. If it is a new damaged surface, surface treatment is not required; If it is an old damaged surface, it needs to be wiped with acetone to dry.
2. For small fragments, you can choose to use 502 glue for bonding; For larger fragments with more blocks, SGA is used for gluing, and the gluing method can be "block by block gluing method".
3. First, stick the two larger pieces together and basically solidify, and then stick the other pieces together. The positioning method can be tied with string or fixed with pressure-sensitive adhesive tape.
4. After folding, wipe off the residual rubber before the rubber powder solidifies. SGA glue can be solidified within 12 hours, thus repairing the broken porcelain cup.
Third, how to clean the cup?
1, with toothpaste
Because detergent contains many chemical components, it is not recommended to use it to clean cups. If there are many stains on the cup, it is recommended to clean the cup with toothpaste. Because toothpaste contains both detergent and fine friction agent, it is easy to remove residual substances without damaging the cup.
Step 2 use baking soda
Dip the toothbrush in baking soda and brush the inside of the cup carefully to remove stains. Baking soda is slightly alkaline and has the same cleaning effect as soap, so use baking soda to clean your cup.
