MHEC (Methyl Hydroxyethyl Cellulose) wani nau'in polymer ne na cellulose wanda aka saba amfani dashi azaman ƙari a aikace-aikacen ma'anar tushen siminti.Yana da fa'idodi iri ɗaya ga HPMC, amma yana da wasu bambance-bambance a cikin kaddarorin.Waɗannan su ne aikace-aikacen MHEC a cikin filastar siminti:
Riƙewar ruwa: MHEC yana ƙara riƙewar ruwa a cikin cakuda plastering, don haka tsawaita aikin aiki.Yana taimakawa hana cakuda daga bushewa da wuri, yana ba da isasshen lokaci don aikace-aikacen da ƙarewa.
Ƙarfafa aiki: MHEC yana inganta aikin aiki da kuma shimfidawa na kayan shafa.Yana inganta haɗin kai da kaddarorin kwarara, yana sauƙaƙa yin amfani da shi da cimma daidaitaccen ƙarewa akan saman.
Adhesion: MHEC yana haɓaka mafi kyawun mannewa na filasta zuwa madaidaicin.Yana taimakawa tabbatar da haɗin gwiwa mai ƙarfi tsakanin filastar da saman da ke ƙasa, yana rage haɗarin delamination ko rabuwa.
Resistance Sag: MHEC tana ba da thixotropy ga cakuda filasta, yana inganta juriyar sag ko slump lokacin amfani da shi a tsaye ko sama.Yana taimakawa wajen kula da kauri da siffar filasta da ake so yayin aikace-aikacen.
Tsagewar juriya: Ta ƙara MHEC, kayan plastering yana samun sassauci mafi girma kuma don haka haɓaka juriya.Yana taimakawa rage faɗuwar faɗuwar faɗuwa ta hanyar bushewa raguwa ko haɓakar zafi.
Durability: MHEC yana ba da gudummawa ga dorewa na tsarin plastering.Yana samar da fim mai kariya lokacin bushewa, haɓaka juriya ga shigar ruwa, yanayin yanayi da sauran abubuwan muhalli.
Gudanar da Rheology: MHEC yana aiki azaman mai gyara rheology, yana shafar gudana da iya aiki na cakuda ma'ana.Yana taimakawa wajen sarrafa danko, yana inganta yanayin yin famfo ko feshi, kuma yana hana daidaitawa ko rarrabuwar tsayayyen barbashi.
Ya kamata a lura cewa takamaiman adadin da zaɓi na MHEC na iya bambanta dangane da ƙayyadaddun buƙatun tsarin plastering, kamar kauri da ake buƙata, yanayin warkewa da sauran dalilai.Masu sana'a sukan ba da jagorori da takaddun bayanan fasaha tare da matakan da aka ba da shawarar amfani da umarni don haɗa MHEC cikin ƙirar gypsum siminti.
