Gịnị bụ MHEC?

Methyl Hydroxyethyl Cellulose (MHEC) bụ cellulose ether na-abụghị ionic nke sitere na cellulose eke, nke a na-enwetakarị site na ihe mkpuchi owu a nụchara anụcha ma ọ bụ ihe e ji osisi mee.

Site na usoro etherification a na-achịkwa, a na-agbanwe cellulose site na kemịkalụ site na iwebata:

  • Ndị otu Methyl
  • Otu Hydroxyethyl

Mgbanwe ndị a na-agbanwe cellulose na-enweghị ike ịgbaze ka ọ bụrụ polima mmiri na-agbaze nke nwere ezigbo ihe ndị na-eme ka ọ sie ike ma na-ejide mmiri.
