Ko te mahi a te hydroxypropyl methyl cellulose i roto i te kumete maku

Te mahi a te HPMC ki te kumete maku

Ko te kumete whakauru makuku: Ko te kumete whakauru he momo sima, he pai te whakahiato, te whakauru me te wai, me te rite ki nga ahuatanga o nga momo waahanga, i roto i tetahi waahanga, i muri i te ine i te teihana whakaranu, whakaranu, ka haria ki te waahi e whakamahia ana e te taraka, ki roto i te ipu rokiroki kua whakatapua, ka whakamahia i roto i te waa kua tohua te ranunga maku kua oti.

Ka whakamahia te Hydroxypropyl methyl cellulose hei kaihoko pupuri wai mo te kumete ciment, te kumete moata retarder.I roto i te gypsum rite te here ki te whakapai ake i te tono me te whakawhānui i te wa mahi, hydroxypropyl methylcellulose HPMC pupuri wai kia kore e te slurry i muri i whakamaroke kia tere rawa, me te kapiti, whakapakeke ki te whakapai ake i te kaha.Ko te pupuri wai he taonga nui o te HPMC hydroxypropyl methyl cellulose HPMC, a ko te awangawanga ano hoki o te maha o nga kaihanga kumete maku.Ko nga mea e pa ana ki te paanga o te pupuri wai o te kumete maku ko te nui o te HPMC kua tapirihia, te pokey o te HPMC, te pai o nga matūriki me te mahana o te taiao whakamahi.
Hydroxypropyl methyl cellulose HPMC i roto i te kumete maku he mahi matua i roto i nga waahanga e toru, ko tetahi he pai te pupuri i te wai kaha, ko te tuarua ko te riterite moata maku me te thixotropy o te awe, ko te tuatoru ko te taunekeneke ki te sima.Ko te pupuri i te wai cellulose ether e whakawhirinaki ana ki te tere o te whakauru wai o te turanga, te hanganga kumete moata, te matotoru o te paparanga kumete, te tono wai moata, te wa whakarite.Ko te teitei ake o te maarama o te hydroxypropyl methyl cellulose, ka pai ake te pupuri wai.
Ko nga mea e pa ana ki te pupuri i te wai o te kumete maku ko te pokey o te cellulose ether, te taapiri i te nui, te rahi matūriki me te pāmahana.Ko te nui ake o te pokey o te cellulose ether, ka pai ake te pupuri wai.Ko te Viscosity he tawhā nui mo te mahi HPMC.Mo te hua kotahi, ma te whakamahi i nga tikanga rereke hei ine i te pokey o nga hua ka rereke te rerekee, ko etahi ma te tauwehe e rua.Na reira, me whakahaere te whakataurite viscosity i roto i te tikanga whakamatautau ano, tae atu ki te pāmahana, rotor, etc.

Ko te tikanga, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai.Engari, ko te teitei ake o te viscosity, ko te teitei ake o te taumaha ngota o te HPMC, me te iti ake o te whakarewatanga o te HPMC, he kino te paanga ki te kaha me te mahi hanga o te moata.Ko te teitei ake o te pokey, ka tino kitea te hua matotoru o te kumete, engari kaore i te hono tika.Ko te teitei ake o te pokey, ka piri ake te kumete maku, he pai te mahi hanga, te mahi kirikiri kirikiri me te piri nui ki te tïpako.Heoi, ko te whakapai ake i te kaha o te hanganga o te kumete maku ano kaore i awhina.Ko nga hanganga e rua, kaore i te kitea te mahi anti-iri.He rerekee, he tino pai te kaha o te hangahanga o te moata maku.
Ko te nui ake o te cellulose ether PMC moata maku i tapirihia, ko te pai ake o te pupuri wai, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai.Ko te pai hoki he tohu mahi nui o te hydroxypropyl methyl cellulose.
Ko te pai o te hydroxypropyl methyl cellulose he awe ano ki tana pupuri wai.I raro i nga ahuatanga noa, ko te ahua ano me te rereke rereke o te hydroxypropyl methyl cellulose, i raro i te nui o te taapiri, he pai ake te iti o te painga o te pupuri wai.
I roto i te kumete maku, he iti rawa te taapiri o te cellulose ether HPMC, engari ka taea te whakapai ake i te mahi hanga o te kumete maku, ko te taapiri matua e pa ana ki te mahi o te kumete.Ko te mahi o te kumete maku ka tino awehia e te kowhiringa tika o te hydroxypropyl methyl cellulose.
