Hydroxypropyl methylcellulose (HPMC) i roto i te kumete ranunga maku

Ko te mahi aHPMC i roto i te kumete whakauru makuku

Ko te moata whakauru makuku he sima, he whakahiato pai, he whakauru, he wai me nga momo waahanga kua whakatauhia i runga i te mahi. E ai ki tetahi waahanga, i muri i te ine me te whakauru ki roto i te teihana whakaranu, ka haria ki te waahi e whakamahia ana e te taraka whakaranu, ka maka ki roto i tetahi waahanga motuhake Ka rongoa te ranunga maku ki roto i te ipu ka whakamahia i roto i te waa kua tohua.

Ka whakamahia te Hydroxypropyl methylcellulose hei kaihoko whakamarumaru mo te slurry ciment me te mea he aukati kia pai ai te pupuhi. Hydroxypropyl-Methyl Cellulose HPMC Cellulose's moisturizing ability as a viscous solution to increase the effectiveness of dab and extends the working time. Ma tenei ka kore e tere te pakaru o te hamana i muri i te whakahinuhinu me te kaha ake i muri i te whakamaroketanga. . Ko te waikawa pūhaumāota he mahi nui a HPMC ki te whakamaroke i te cellulose, a he kaihanga o te maha o nga penupenu i Haina. Ko nga mea e pa ana ki te slurry maku ko te nui o te taapiri HPMC, te pokey HPMC, te pai o te matūriki me te pāmahana ambient.

Ko te mahi nui o te HPMC i roto i te ranunga maku e tino kitea ana i roto i nga waahanga e toru: ko tetahi he pai te kaha pupuri wai, ko tetahi atu ko te awe i runga i te riterite me te whakarereketanga o te makuku, me tetahi atu ko te taunekeneke ki te sima. Ko te nui o te cellulose ether e whakawhirinaki ana ki te tangohanga o te wai e te tïpako, te hanganga o te onepu, te matotoru o te paparanga, te hiahia mo te wai i roto i te wairewa, me te wa whakawera o te rauemi.

Ko nga mea e pupuri ana i te makuku e pa ana ki te cellulose hydrolyzed ko te pokey penupenu, te nui o te taapiri, te pai o te matūriki me te pāmahana. Ko te matotoru o te cellulose ether, ko te pai ake o te aukati wai. Ko te Viscosity he tawhā mahi nui o HPMC. Mo te hua kotahi, he rereke nga hua pokey e inehia ana e nga tikanga rereke, a ko etahi ka eke ki te ahu whakamua ahuahanga. Na reira, ki te whakataurite i nga poikeke, me mahi i waenga i nga tikanga whakamatautau, tae atu ki te pāmahana, te miro, me era atu.

Ko te tikanga, ko te teitei ake o te pokey, ko te pai ake o te mahi parewai. Engari ka nui ake te piki o te pokey, HPMC, ka nui ake te taumaha ngota, ka iti ake nga ahuatanga whakarewatanga, ka kaha te otinga, ka raru kino nga taonga. Ko te teitei ake o te pokey, ko te pai ake o te whakakaha i roto i te otinga, engari kaore i te rite ki te tauwehenga. Ko te teitei ake o te pokey, te makuku me te kaha ake o te wairewa, i te wa e hanga ana, e whakaatu ana i te kaha kaha ki te aroaro o nga matatahi me nga rawa. Engari ko te taapiri i te kaha o te hanganga ki te kumete maku e kore e awhina. I te wa i hangaia ai nga whare e rua, ka kitea kua ngaro te mahi a te namu. He rereke, ko etahi waikawa methacrylic i muri i te whakakini-iti, i te mea ko te cellulose te whakapai ake i te otinga maku me te kaha o te hanganga, he tino pai nga ahuatanga.
