Etera Cellulose– Matotoru me te Thixotropy
Ether Celluloseka whakawhiwhia te kumete maku ki te tino pokey, ka taea te whakanui ake i te piri ki waenga i te kumete maku me te paparanga turanga, te whakapai ake i te mahi anti rere o te kumete, a ka whakamahia nuitia ki te raima moata, te kumete whakapiri tira raima, me te punaha whakaahuru taiepa o waho.Ka taea hoki e te whakakaha o te cellulose ether te whakanui ake i te kaha anti dispersion me te riterite o nga rawa hou, me te aukati i te stratification rauemi, te wehenga, me te mahanga.Ka taea te whakamahi mo te raima whakakaha ake i te muka, te raima i raro i te wai, me te raima whakakii whaiaro.
Ko te whakakaha o teether cellulosei runga i nga rauemi ciment ka puta mai i te pokey o te otinga cellulose ether.I raro i te taua tikanga, te teitei te pokey oether cellulose, ko te pai ake o te viscosity o nga rauemi e hangai ana ki te ciment.Heoi, ki te nui rawa te pokey, ka pa ki te rere me te mahi o te rauemi (penei i nga maripi raima).Ko te kumete whakamaarama whaiaro, te raima whakatoo whaiaro, me etahi atu mea he nui te rere o te wai, he iti rawa te pokey o te cellulose ether.I tua atu, ko te whakakaha o te cellulose ether ka nui ake te hiahia o te wai o te tïpako ciment me te whakanui ake i te hanga moata.
He thixotropy teitei te wairewa wai o te cellulose ether pokey teitei, he ahuatanga ano o te cellulose ether.Ko te wairewa wai o te methyl cellulose i te nuinga o te waa he pseudoplastic me te kore thixotropic rerenga he iti ake i tona pāmahana reera, engari ka whakaatu te rere Newtonian i te tere kutikuti iti.Ahakoa te momo me te tohu o te whakakapinga o nga mea whakakapi, ka piki te pseudoplasticity i te pikinga o te taumaha ngota me te kukū o te cellulose ether.No reira, i te mea ka noho tonu te kukū me te pāmahana, ka rite tonu te ahua o nga etero cellulose (ahakoa te MC,HPMC, HEMC) he rite tonu nga ahuatanga rheological.Ka piki ake te pāmahana, ka puta te hanga o te kiri ka puta te rere thixotropic teitei.
Ether Celluloseka kii nga kaihanga ki a koe ko te cellulose ether me te kukū teitei me te iti o te pokey he thixotropy ahakoa i raro i te pāmahana reera.He tino painga tenei taonga mo te hanga moata ki te whakatika i te taumata me te whakaheke.Me tohu ko te teitei ake o te viscosity oether cellulose, ka pai ake tana pupuri wai.Heoi, ko te teitei ake o te pokey, ka teitei ake te taumahatanga ngota ngota o te cellulose ether, me te hekenga o tona whakarewatanga.He painga kino ki te kukū me te kaha o te mahi moata.
Etera Cellulose- Kua roa
Ether CelluloseKa taea te whakaroa i te wa whakatuu o te slurry sima, te kumete ranei, te whakaroa i te kinetics hydration o te sima, me te whakapai ake i te oranga o nga rauemi hou, na reira ka pai ake te rite o te tanga i waenga i te kumete me te raima.Ko te tohu o te mate i roto i te waa, engari ka whakaroa pea te ahunga whakamua o te hanga.
