Ko te hydroxypropyl methyl cellulose HPMC kua whakarewahia ki te kumete maku

Ko te wairewa hydroxypropyl methyl cellulose (HPMC) he momo ether cellulose kore-ionic, he mea hanga mai i te cellulose polymer taiao na roto i te raupapa o te tukatuka matū. Ko te Hypromellose (HPMC) he paura ma ka memeha i roto i te wai matao hei hanga i te otinga maramara, wairewa. Kei a ia nga ahuatanga o te matotoru, te piri, te marara, te whakaemulsification, te hanga kiriata, te whakatārewatanga, te adsorption, te gelation, te mahi mata, te pupuri wai me te whakamarumaru colloid. Ko te pupuri wai he taonga nui o te HPMC hypromellose, e maaharahara ana hoki te maha o nga kaihanga kumete-makuku i Haina. Ko nga mea e pa ana ki te pupuri i te wai o te kumete whakauru makuku ko te nui o te HPMC, te viscosity o te HPMC, te rahi matūriki me te pāmahana o te taiao. Ko te HPMC hypromellose he mahi nui i roto i te kumete i roto i nga waahanga e toru: tona pai te pupuri i te wai, tona paanga ki te riterite moata me te thixotropy, me tana taunekeneke ki te ciment. Ko te mahi pupuri wai o te cellulose ether e whakawhirinaki ana ki te whakauru wai o te turanga, te hanganga o te moata, te matotoru o te moata, te hiahia o te wai mo te moata me te wa whakatuu o te taputapu. Ko te marama ake o te hypromellose, ka pai ake te pupuri wai.https://www.longouchem.com/hpmc/

Ko nga mea e pa ana ki te pupuri wai o te kumete ko te pokey o te cellulose ether, te nui o te taapiri, te pai o te matūriki me te pāmahana ratonga. Ko te nui ake o te pokey o te cellulose ether, ka pai ake te pupuri wai. Ko te Viscosity tetahi waahanga nui o te mahi HPMC. Mo te hua kotahi, ka inehia e nga tikanga rereke o nga hua viscosity he rerekee, ko etahi ka ruarua te rereketanga. Na reira, ka whakatairite i te pokey, me rite te tikanga whakamatautau i waenga, tae atu ki te pāmahana, rotor me era atu. I te nuinga o te korero, ko te teitei ake o te pokey, ko te pai ake te painga o te pupuri wai. Engari, ko te teitei ake o te pokey, ko te teitei ake o te taumaha ngota o te HPMC, ka heke te whakarewatanga o te HPMC, he kino tenei ki te kaha me te mahi hanga o te kumete. Ko te teitei ake o te viscosity, ko te pai ake o te whakapawera o te kumete, engari kaore i te rite ki te hononga. Ko te teitei ake o te pokey, ka kaha ake te moata makuku, mo te hanga, te mahi o te kiripiri me te piri nui ki te tïpako. Engari ehara i te mea pai ki te whakanui ake i te kaha o te hanganga o te kumete maku ano. Hanga e rua, mahi mo te mahi anti-sagging. He rereke, ko etahi hypromellose kua whakarerekehia me te iti ki te pokey reo kua whakaatu i te mahi pai ki te whakapai ake i te kaha o te hanganga o nga moata maku. Ko te teitei ake o te ihirangi o te cellulose ether i roto i te kumete, te pai ake o te taonga pupuri wai, te teitei ake o te pokey me te pai ake o te taonga pupuri wai. Ko te pai he tohu mahi nui mo te hypromellose. Ko te pai o te hypromellose he paanga ano ki tona kaha pupuri wai. I te nuinga o te waa, mo te hypromellose he rite tonu te pokey engari he rereke te pai, i raro i te nui o te taapiri, he pai ake te pai, he pai ake te painga o te pupuri wai.https://www.longouchem.com/hpmc/

I roto i te moata-makuku, he iti rawa te taapiri o te cellulose ether HPMC, engari ka taea e ia te whakapai ake i te mahi hanga o te moata whakauru makuku. Ko te kowhiringa tika o te hypromellose he painga nui ki te mahi o te kumete whakauru makuku.
