Starch ether
Ejiri ya na methyl cellulose ether, ọ na-egosi mmetụta synergistic dị mma n'etiti abụọ ahụ.Ịgbakwunye ether starch kwesịrị ekwesị na methyl cellulose ether nwere ike ime ka nkwụsị nke sag na nkwụsị nke ngwa agha dịkwuo mma, ma nwee uru mkpụrụ dị elu.
N'ime ngwa agha nwere methyl cellulose ether, ịgbakwụnye ether starch kwesịrị ekwesị nwere ike ịbawanye nkwụsi ike nke ngwa agha ahụ nke ọma ma mee ka mmiri dị mma dịkwuo mma, na-eme ka ihe owuwu ahụ dị nro ma na-ekpochasị ihe dị nro.
N'ime ngwa agha nwere methyl cellulose ether, ịgbakwụnye ihe kwesịrị ekwesị nke starch ether nwere ike ime ka njigide mmiri nke ngwa agha ahụ dịkwuo ogologo ma gbatịa oge.
Starch ether bụ starch ether soluble nke kemịkal na mmiri, dakọtara na mgbakwunye ndị ọzọ na ntụ ntụ ntụ, nke a na-ejikarị eme ihe na tile adhesives, nrụzi ngwa agha, plasta plasta, ime na mputa mgbidi putty, gypsum dabeere caulking na ndochi ihe, interface ihe, ngwa agha masonry.
A na-ejikarị starch ether eme ihe na ngwa agha, nke nwere ike imetụta nkwụsị nke ngwa agha dabere na gypsum, ciment na lime, ma gbanwee ihe owuwu na sag resistance nke ngwa agha.A na-ejikarị ethers starch eme ihe na njikọ cellulose ethers na-adịghị agbanwe agbanwe na emezigharị.Ọ dabara maka ma na-anọpụ iche na alkaline usoro, na dakọtara na ọtụtụ ihe mgbakwunye na gypsum na ciment ngwaahịa (dị ka surfactants, MC, starch na mmiri-soluble polymers dị ka polyvinyl acetate).
Njirimara nke starch ether na-adabere na:
⑴Mee nguzogide sag;
⑵ Meziwanye ihe owuwu;
⑶ Melite ogo njide mmiri nke ngwa agha
