Te Paanga o te Hydroxypropyl Methyl Cellulose HPMC ki te Wa Whakataunga o te Raima

Ko te wa whakarite o te raima e tino pa ana ki te wa waahi o te ciment, a, kaore i te nui te awe o te whakahiato.No reira, ko te paanga o te hydroxypropyl methylcellulose HPMC i runga i te wa whakatuu o te ranunga raima kore-kore ki raro i te wai ka taea te ako i roto i te wa whakatakoto o te kumete.Mai i te wa o te waahi o te moata e pa ana ki te wai, hei aromatawai i te paanga o te HPMC i runga i te wa waahi o te moata, me whakatika te owehenga wai-ciment me te waahanga moata o te moata.

Ko nga hua whakamatautau e whakaatu ana ko te taapiri o te hydroxypropyl methylcellulose HPMC he nui te paheketanga ki te ranunga moata, a, ka roa te wa tautuhi o te moata me te piki o te nui o te hydroxypropyl methylcellulose.I roto i te ahua o nga ihirangi HPMC, ko te moata i hangaia i raro i te wai he pai ake i te moata i hangaia i te hau.He roa ake te hanga o te hangahanga waenga.I te ine i roto i te wai, ka whakatauritea ki te tauira patea, ko te wa whakatuu tuatahi o te kumete i konatunatua ki te hydroxypropyl methylcellulose i whakaroa e 6-18 haora, a ko te wa whakatuu whakamutunga i whakaroa e 6-22 haora.Na reira, me whakamahi te HPMC me nga kaihoko kaha moata.

Ko te HPMC he waerau ngota teitei me te hanganga raina macromolecular.Ko tana roopu mahi he roopu hydroxyl, ka taea te hanga i nga here hauwai me nga ngota ngota wai whakauru me te whakanui ake i te pokey o te wai whakauru.Ko nga mekameka ngota roa o te HPMC ka kukume tetahi ki tetahi, ka hono nga ngota ngota HPMC ki te hanga i te hanganga whatunga, te takai sima me te whakaranu wai.I te mea ka hangaia e te HPMC he hanganga whatunga penei i te kiriata ki te takai i te sima, ka taea e ia te aukati i te paheketanga o te wai i roto i te kumete, me te aukati, te whakaheke ranei i te tere o te whakamakuku o te sima.
