He aha nga mea ka pa ki te pokey o te hydroxypropyl methylcellulose?

Mo te whakamahinga o te kumete maku, he pai nga ahuatanga o te hydroxypropyl methylcellulose, ka nui ake te kaha o te honohono i waenga i te kumete maku me te paparanga turanga, ka taea hoki te whakapai ake i te mahi anti-sag o te kumete, na reira ka whakamahia nuitia ki te raima moata, waho. te punaha whakaahuru pakitara me te kumete here pereki.

Hoki te pānga thickening o cellulose Ether, ka taea hoki te whakanui i te reira i te ōritetanga me te anti-marara te kaha o nga rauemi e hāngai ana ki te ciment hou i konatunatua, a ka taea hoki te aukati i nga raruraru o te delamination, wehe me te toto i roto i te kumete me te raima. Ka taea te whakamahi ki te raima whakakaha i te muka, te raima i raro i te wai me te raima whakakii-whaiaro.

Ka taea e te Hydroxypropyl methylcellulose te whakanui ake i te kaha o te hanga o nga taonga hanga-sima. Ko tenei mahinga ka ahu mai i te pokey o te otinga cellulose ether. Ko te tikanga, ka whakamahia te taurangi tau o te pokey ki te whakawa i te pokey o te otinga cellulose ether, i te mea ko te cellulose Ko te pokey o te ether te nuinga e pa ana ki tetahi kukū o te otinga cellulose ether, te tikanga 2%, i te pāmahana kua tohua, penei i te 20 nga nekehanga me te he tere hurihanga, ma te whakamahi i tetahi taputapu ine kua tohua, penei i te viscometer hurihuri. Uara Viscosity.

Ko te Viscosity tetahi o nga waahanga nui hei arotake i te mahi o te cellulose ether. Ko te teitei ake o te viscosity o te otinga hydroxypropyl methylcellulose, ko te pai ake o te viscosity o nga rauemi ciment, me te pai ake o te mahi adhesion ki te tïpako. I te wa ano, kei a ia Ko te kaha anti-sagging me te kaha anti-dispersion he kaha ake, engari ki te mea he tiketike rawa tona viscosity, ka pa ki te rere o te rere me te operability o nga rauemi ciment-based.

He aha nga mea ka pa ki te pokey o te hydroxypropyl methylcellulose? Ko te nuinga ka whakawhirinaki ki nga take e whai ake nei.

1. Ko te teitei o te tohu polymerization o te cellulose ether o te hydroxypropyl methylcellulose, ka nui ake te taumaha o te ngota, ka nui ake te pokey o tana wairewa wai.

2. Mena he nui ake te nui me te kukū o te cellulose ether, ka nui ake te pokey o tana wairewa wai. Heoi, kia tupato ki te kowhiri i te nui o te cellulose ether ina whakamahia ana, ko te nuinga ki te karo i te nui rawa o te cellulose ether. Ka pa ki te mahi o te moata me te raima.

3. Pērā i te nuinga o te wai, ka heke te pōkākā o te otinga cellulose ether i te pikinga o te pāmahana, me te teitei ake o te kukū o te cellulose ether, ka iti ake te pāmahana. Ko te nui ake o te paanga.

4. Ko te otinga ether cellulose he pseudoplastic, he ahua o te kutikuti angiangi. Ko te nui ake o te tere kutikuti i te wa o te whakamatautau, ka iti ake te pokey.

Ka whakahekehia te whakakotahitanga o te kumete na te kaha o te kaha o waho, he pai hoki ki te weriweri i te hanga moata, na te pai o te whakakotahi me te mahi o te moata i te wa ano. Engari, ki te mea he nui ake te kukū o te otinga cellulose ether Ina he iti te pokey me te iti o te pokey, ka whakaatuhia nga ahuatanga o te wai Newtonian. Ka piki ake te kukū, ka āta whakaatuhia e te otinga nga ahuatanga o te wai pseudoplastic, a, ki te teitei ake te kukū, ka tino kitea te pseudoplasticity.
