HPMC YB 515M

EipponCell HPMC YB 515M, yopangidwira zomatira zomata matailosi, ili ndi zotsatirazi:

Chikoka pa nthawi yotseguka ya zomatira matailosi

Pamene ufa wa latex ndi cellulose ether HPMC ulipo mumatope onyowa, ufa wa RDP umasonyeza mphamvu zomangirira kwambiri ndi simenti ya hydration mankhwala, pamene cellulose ether imakhudza makamaka madzi apakati, omwe amakhudza kukhuthala komanso nthawi ya matope.

RDP ufa umasonyeza kuwonjezereka kwa zinthu za simenti za hydration, pamene cellulose ether imakhudza makamaka madzi amadzimadzi, kukhudza kukhuthala kwamatope ndi nthawi yoikika.

Kukhalapo kwa latex powder ndi cellulosic ether HPMC mumatope amadzimadzi kumakhudza katundu wa matope, ndi ufa wa RDP wokhala ndi mphamvu zazikulu zomangirira ndi cellulosic ether yomwe imakhudza kukhuthala ndi kuika nthawi kudzera mu kupezeka kwake mumadzimadzi.

Chikoka pa mphamvu yokoka ya zomatira matailosi

Ma cellulose ether mumatope sikuti amangopereka zinthu zopindulitsa, komanso amachedwetsa mphamvu ya hydration ya simenti mwa kutsatsa pamtengo wa hydrate m'malo mwa gawo loyambirira la mchere.Kuchedwetsaku kumachitika chifukwa cha kuchepa kwa ma ayoni mu pore yankho chifukwa cha kukhuthala kochulukira komwe kumachitika chifukwa cha cellulose ether.

Kukhalapo kwa cellulose ether m'makina a simenti kumalepheretsa hydration kinetics potsatsa malonda a hydrated m'malo mwa gawo loyamba la mchere, komanso kukulitsa kukhuthala kwa pore solution, potero kumachepetsa kuyenda kwa ion ndikuchepetsanso njira ya hydration.

Cellulose etha retardation zotsatira pa simenti hydration makamaka zimatheka ndi adsorption ake pa mankhwala hydrated ndi kuwonjezereka kwa mamasukidwe akayendedwe a pore yankho, amene amalepheretsa ion kuyenda ndi kuchedwetsa wonse hydration mphamvu.
