8.Control of Hydration Kinetics

HPMC yana rinjayar motsin motsa jiki na tsarin siminti ta hanyar daidaita wadatar ruwa da ions, da kuma haɓakawa da haɓaka samfuran hydration. Kasancewar HPMC na iya ja da baya ko haɓaka aikin samar da ruwa ya danganta da abubuwa kamar nau'in, taro, da nauyin kwayoyin halitta na HPMC, da kuma yanayin warkewa.

9.Ingantattun Kayayyakin Injini

Abubuwan siminti da aka gyara na HPMC suna nuna ingantattun kaddarorin inji idan aka kwatanta da tsarin tushen ciminti. gyare-gyaren ƙananan gyare-gyaren da HPMC ke haifar da shi yana haifar da ƙarfin matsawa, ƙarfin sassauƙa, da tauri, da kuma ingantaccen juriya ga fashewa da lalacewa a ƙarƙashin kaya.

10.Ingantattun Dorewa

HPMC yana haɓaka dorewar kayan siminti ta hanyar haɓaka juriyarsu ga hanyoyin lalata iri-iri, gami da daskarewar hawan keke, harin sinadarai, da carbonation.
