Oge ịhazi ihe bụ ihe metụtara oge nrụnye, yana enwere ike iji ngwakọta nke hpmc, ya mere iji tụọ mmetụta nke mmiri na mmiri A ga-edozigharị ciment.

HPMC bụ Macromolecule Linear Style, ya na otu hydroxyl na ọrụ ọrụ, nke nwere ike imepụta njikọ hydrogen site na ụmụ irighiri mmiri na-abawanye nke mmiri agwakọta. HPMC ogologo molecular ga-adọta ibe ya, yabụ na Hpmc Molecules na ibe ya na ibe ya iji mepụta ihe owuwu, ciment, agwakọta mmiri.
