  • Application example of CMC in acidic milk drink

    1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....

  • How to use tile adhesive correctly

    Clean the back of the tile first. If the stains, floating layer and residual release powder on the back of the tiles are not cleaned up, it is easy to gather and fail to form a film after the adhesive is applied. Special reminder, the cleaned tiles can only be painted with adhesive after they are...
