HydroxyPropyl Methyl Cellulose hpmc ni selile itari ionic ikozwe muri selile ya selile ya selile ya selile ya pollemer binyuze murukurikirane rwibikoresho byo gutunganya imiti. Nibintu bidafite impumuro nziza, bitazirikana kandi bidafite uburozi bubyimba pulloidal isobanutse cyangwa gato ya turbid mumazi akonje. Ifite ibiranga ibiranga, guhuza, gutatanya, guhiga, guhagarika film, ihagarikwa, ibanga, pelation, ibikorwa byubushuhe no kurinda ubushuhe kandi birinda colloid. HydroxyPropyl Methylcellse irashobora gukoreshwa mu bikoresho byo kubaka, kunganya inganda, inganda za Simbeti, imiti, ibiryo, ibiryo, ubuhinzi, inganda z'imiti n'izindi.
Imikorere yo kugumana amazi ni ihame: Ubudozi Ether Hpmc cyane cyane bugira uruhare mu kugumana amazi no kubyimba muri cemer na gypsum, bikaba bishobora kunoza neza imbaraga hamwe na sag kurwanya indwara. Ibintu nkubushyuhe bwikirere, ubushyuhe hamwe numuvuduko wumuvuduko wumuyaga bizagira ingaruka kumibare y'amaraso muri sima na parpsum. Kubwibyo, mubihe bitandukanye, hari itandukaniro ryingaruka zo kugumana amazi yibicuruzwa bimwe na HPMC. Mubwubatsi bwihariye, ingaruka zo kugumana amazi zirashobora guhindurwa no kwiyongera cyangwa kugabanya umubare wa HPMC yongeyeho.
Kugumana amazi ya methyl selile ether imiterere yubushyuhe nicyo kimenyetso cyingenzi kugirango utandukane ubwiza bwa methyl. Ibicuruzwa byiza bya HPMC birashobora gukemura neza ikibazo cyo kugumana amazi ku bushyuhe bwo hejuru. Mubihe byubushyuhe bwinshi, cyane cyane mubice bishyushye kandi byumye kandi byubatse byubwubatsi bwizuba, HPMC yo hejuru ya HPMC isabwa kunoza ubushake bwo kugumana amazi.
Ubuziranenge bwa HPMC ifite uburinganire bwiza cyane. Uburyo bwamatsinda ya HydroxyPropy na HydroxyPropoplex yagabanijwe neza kuruhande rwa molekile, bishobora kunoza ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ethers ingoma yo kwiteranya namazi kugirango ikore hydrogen. , Kugirango amazi yubusa ahinduke amazi, bityo agasuzumisha neza imyambaro y'amazi iterwa nubushyuhe bwinshi, kandi igera ku kugumana mu mazi menshi.
Ubudodo bukomeye HPMC irashobora gutatana neza kandi neza muri sima ya pertar na gysum, hanyuma uzenguruke ibice byose bikomeye, kandi bibe umwanya wa firime itose. Amazi munsi shingiro arasohoka buhoro buhoro mugihe kirekire. Ibikoresho byegeranye bikongerwaho hydration reaction, kugirango tumenye imbaraga zimishano nimbaraga zimiterere yibikoresho. Kubwibyo, mubushyuhe bwizuba ryizuba, kugirango tugere ku ngaruka zo kugumana amazi, ibicuruzwa byisumbuye bya HPMC bigomba kongerwaho muburyo buhagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire, bitabaye ibyo, kugabanya imbaraga, gutobora no kugwa bizabaho kubera gukama gukabije. Ibibazo, ariko kandi byongera ingorane zubwubatsi. Nkuko ubushyuhe bugabanuka, umubare wa HPMC wongeyeho urashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo kugumana amazi zirashobora kugerwaho.
Kugumana amazi ya HPMC bigira ingaruka kubintu bikurikira:
1. Guhuza ubumwe bwa selile ether hpmc
Mu byishimo byatewe na HPMC, uburyo na hydroxyPropopxy bwatanzwe burundu, kandi igipimo cyo kugumana amazi ni kinini.
2. Ubushyuhe bwa Gel Ubushyuhe bwa Cellulose Ether HPMC
Ubushyuhe bwa Gel Ubushyuhe ni hejuru, igipimo cyo gutukana amazi ni kinini; Ibinyuranye, umubare wogumana amazi ni muto.
3. Isushi ya selile ether hpmc
Iyo virusi ya HPMC yiyongera, umubare wogumana amazi nawo uriyongera; Iyo ubushyuhe bugeze kurwego runaka, ubwiyongere bwogumana amazi bukunda kuba igorofa.
4. Ongeraho selile ether hpmc
Ingano nini ya selile Ether HPMC yongeyeho, igipimo cyo guhohotera amazi ningaruka nziza yo kugumana amazi. Mu rwego rwa 0.25-0.6 Iyo amafaranga yo kwigomeka yiyongera, uburyo bwo kwiyongera bwa kanseri y'amazi butinda.
