Hydroxypropyl methylcellulose, ikunze kwitwa HPMC, ni selile ikomoka cyane mu nganda zitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, ubwubatsi, n'ibindi. Kimwe mu bintu bidasanzwe bya HPMC ni ubushobozi bwayo bwo kugumana amazi. HPMC irashobora gukurura no kugumana amazi menshi, itanga umubyimba mwiza, geli hamwe noguhindura ibicuruzwa byinshi. Nyamara, ubushobozi bwo gufata amazi ya HPMC bufitanye isano nibintu byinshi, harimo n'ubushyuhe.
Ubushyuhe ni kimwe mu bintu by'ingenzi bigira ingaruka ku gufata amazi ya HPMC. Ubushyuhe hamwe nubwiza bwa HPMC biterwa nubushyuhe. Muri rusange, HPMC irashonga cyane kandi igaragara neza mubushyuhe bwinshi. Mugihe ubushyuhe bwiyongereye, iminyururu ya molekile ya HPMC igenda igendanwa, kandi molekile zamazi zifite amahirwe menshi yo gukorana na hydrophilique ya HPMC, bigatuma amazi menshi agumana. Ibinyuranye na byo, ku bushyuhe bwo hasi, iminyururu ya molekile ya HPMC irakomeye, kandi biragoye ko molekile y'amazi yinjira muri matrike ya HPMC, bigatuma amazi agumana.
Ubushyuhe nabwo bugira ingaruka kumikorere yo gukwirakwiza amazi muri HPMCs. Bitewe n'ubwiyongere bw'amazi y'iminyururu ya HPMC, kwinjiza amazi no gufata amazi ya HPMC biri hejuru mubushyuhe bwinshi. Ku rundi ruhande, igipimo cyo kurekura amazi muri HPMC kirihuta ku bushyuhe bwo hejuru kuko ubushyuhe bwo hejuru bwongera ingufu z’ubushyuhe bwa molekile y’amazi, bikaborohera guhunga matrike ya HPMC. Kubwibyo, ubushyuhe bugira ingaruka zikomeye kumazi no kurekura HPMC.
Kubika amazi ya HPMC mubushyuhe butandukanye bifite ingaruka zifatika. Mu nganda zimiti, HPMC ikoreshwa cyane nka binder, disintegrant, na agent-igenzura irekura ibinini. Kugumana amazi ya HPMC ni ngombwa kugirango itange imiti ihamye kandi nziza. Mugusobanukirwa ingaruka zubushyuhe mukubika amazi ya HPMC, abayashiraho barashobora guteza imbere ibinini binini kandi byiza bishobora kwihanganira uburyo bwo kubika no kohereza. Kurugero, niba ibinini bibitswe cyangwa bitwarwa mugihe cyubushyuhe bwo hejuru, HPMC ifite amazi menshi irashobora gutoranywa kugirango igabanye gutakaza amazi, bishobora kugira ingaruka kumikorere no mumikorere yicyo kibaho.
Mu nganda z’ibiribwa, HPMC ikoreshwa nka emulifisiyeri, ikabyimbye kandi ikanabuza ibicuruzwa bitandukanye nka sosi, isupu hamwe nubutayu. Amazi yo kubika amazi ya HPMC arashobora kugira ingaruka kumiterere, ubwiza no guhagarara kwibicuruzwa byibiribwa. Kurugero, HPMC ifite amazi menshi irashobora gutanga ice cream hamwe nuburyo bworoshye mugihe ikomeza guhagarara neza mugihe cyo kubika no gutwara mubushyuhe butandukanye. Mu buryo nk'ubwo, muburyo bwo kwisiga, HPMC ikoreshwa nkibibyimbye, binder na emulsion stabilisateur. Kugumana amazi ya HPMC birashobora kugira ingaruka zikomeye kubuzima, kwisiga no kubika ubuzima bwibintu byo kwisiga. Kubwibyo, abategura bakeneye gusuzuma ingaruka zubushyuhe kumiterere yo gufata amazi ya HPMC kugirango barebe imikorere myiza nubuziranenge bwibicuruzwa byanyuma.
Imikorere yo gufata amazi ya HPMC yibasiwe cyane nubushyuhe. Ububasha, ubwiza, kwinjiza amazi no kurekura ibintu bya HPMC byose bihindurwa nihindagurika ryubushyuhe, bigira ingaruka kumikorere ya HPMC mubikorwa bitandukanye. Gusobanukirwa nubushyuhe bushingiye ku kubika amazi ya HPMC ni ingenzi mu guteza imbere uburyo bunoze kandi bukomeye ku nganda zitandukanye. Kubwibyo, abashakashatsi naba formulaire bagomba gutekereza ku ngaruka zubushyuhe kumiterere yo gufata amazi ya HPMCs kugirango barusheho kunoza imikorere yabo no kuzamura imikorere yabo.
