Ngwa nke hydroxypropyl methylcellulose na gypsum ngwa agha

Nnwale nnwale ngwa nke hydroxypropyl methylcellulose:
1. Nnwale ike: Mgbe ulechara, gypsum dabeere na hydroxypropyl methylcellulose nwere ezigbo ike njikọ ike na ike mkpakọ.
2. Nnwale mgbochi-sagging: Enweghị sag mgbe a na-etinye ihe owuwu otu ngafe na akwa akwa, na enweghị sag mgbe etinyere ihe karịrị ngafe abụọ (n'elu 3cm), na plasticity dị mma.
3. Nnwale nkwudo mgbidi: ọ na-adị ọkụ ma dị nro mgbe ọ na-ekowe, enwere ike ịkpụzi ya n'otu oge. N'elu dị nro ma dị nro, nwere nchapụta.
