I-MHEC LH 640M

I-EipponCell MHEC LH 640M, eyi-methyl hydroxyethyl cellulose, isetyenziswa ngokuqhelekileyo kwi-dry-mixed mortar.Nantsi inkcazo yamanqaku aphambili akhankanywe kwisicatshulwa:

Ukugcinwa kakuhle kwamanzi: I-MHEC iqinisekisa ukuba udaka lugcina amanzi aneleyo, lukhusela imiba efana nesanti, i-powdering, kunye nokunciphisa amandla okubangelwa ukungabikho kwamanzi kunye ne-cement hydration engaphelelanga.Iphucula ukufana, ukusebenza, kunye nokuqina kwemveliso.Njengoko isixa se-MHEC esongeziweyo sinyuka, uxinzelelo lwesivuno kunye ne-viscosity ye-frown yomdaka nayo iyanda.

I-arhente yokungenisa umoya: I-MHEC inokusebenza njenge-agent-entraining agent.Umgangatho ophezulu womoya kumdaka ufezekiswa xa isixa se-MHEC si-0.5%.Nangona kunjalo, xa inani lidlula i-0.5%, umxholo womoya uyancipha ngokuthe ngcembe, okukhokelela ekunciphiseni amandla okuguquguquka kunye namandla oxinzelelo.

Ukuphuculwa kokusebenza: Ukongezwa kwe-MHEC kuququzelela ukusetyenziswa kakuhle kodaka olucekethekileyo kunye nodaka lokutyabeka.I-MHEC iyalibazisa i-hydration ye-particle particles, kwaye i-degree of substitution (DS) idlala indima ebalulekileyo kule nkqubo yokulibaziseka kwe-hydration.Impembelelo yomxholo we-methoxyl ekubambezelekeni kwe-hydration ibaluleke kakhulu kunomxholo we-hydroxyethyl.

Kubalulekile ukuba uqaphele ukuba i-cellulose ether inefuthe elibini ekusebenzeni kodaka.Ukusebenza kwayo kuxhomekeke kusetyenziso olufanelekileyo;ukusetyenziswa okungafanelekanga kunokuba nemiphumo emibi.Ukusebenza kodaka oluxubeneyo olomileyo luphenjelelwa zizinto ezifana nokuhambelana kwe-cellulose ether kunye nemali kunye nokulandelelana kwongezwa.Kwiinkqubo ezisebenzayo, uhlobo olulodwa lwe-cellulose ether lunokukhethwa, okanye iintlobo ezahlukeneyo zingasetyenziswa ngokudibeneyo.
