Na ngwa agha ciment na gypsum methylcelllose na-arụ ọrụ nke njigide mmiri na oke, nke nwere ike ime ka ike ndị na-eguzogide ihe ndị ahụ.
Ihe ndị dị ka ikuku ikuku, okpomọkụ na oke ikuku ga-emetụta oke mmiri na ngwaahịa ciment na ngwaahịa gypsum-nke. Therefore, in different seasons, there are some differences in the water retention effect of products with the same amount of hydroxypropyl methylcellulose added.
N'ebe a na-ewu ihe, enwere ike idozigharị mmiri nke slurry site na ịbawanye ma ọ bụ na-ebelata ego HPMC agbakwunyere. Ndozi mmiri nke methyl sel n'okpuru ọnọdụ okpomọkụ bụ ihe ngosipụta dị mkpa iji mata ọdịiche dị na ogo merth.
Ngwaahịa HydroxypPropyyl Methylcellose nwere ike idozi nsogbu nke njigide mmiri n'okpuru okpomọkụ dị elu. Na oge okpomọkụ dị elu, karịsịa na ebe na-ekpo ọkụ na nke a na-ewu ewu na-ewu ewu, a chọrọ hpmc dị elu iji meziwanye mmiri nke slurry.
HPMC HPMC dị elu nwere ezigbo mma. A na-ekesa Methoxy na Hydropopopopopopopopopopopopoxy na mkpụrụ osisi cellulose, nke nwere ike ime ka ike nke atọm oxygen na hydroxy na-ejikọ hydrogen jikọtara ọnụ. , nke mere mmiri na-enweghị mmiri na-agba mmiri, ka ị na-achịkwa ikuku nke mmiri nke mmiri ihu igwe na-esite na elu okpomọkụ nke ihu igwe dị elu nke ihu igwe dị elu nke ihu igwe dị elu nke ihu igwe na-akpata.
A chọrọ mmiri maka hydration iji tụọ ihe omume ciment dị ka ciment na gypsum. Ihe ziri ezi nke hpmc nwere ike idobe mmiri n'ime oge zuru ezu ka ọnọdụ ya na usoro siri ike nwere ike ịga n'ihu.
Ọnụ ego HPMC chọrọ iji nweta njigide mmiri zuru ezu dabere:
