HPMC (hydroxypropyl methylcellulose) ni inyongeramusaruro yingenzi ikoreshwa mubikoresho byubwubatsi nka poro yifu, ibifuniko, ibifatika, nibindi. Ifite imirimo myinshi nko kubyimba, gufata amazi, no kunoza imikorere yubwubatsi. Mu gukora ifu ya putty, kongeramo HPMC ntibishobora gusa kunoza amazi yibicuruzwa, ahubwo binongerera igihe cyubwubatsi, birinda ibishishwa gukama vuba mugihe cyubwubatsi, kandi bigira ingaruka mubikorwa byubwubatsi.
1. Hitamo icyitegererezo cyiza cya HPMC
Imikorere ya HPMC ifitanye isano rya bugufi nuburemere bwa molekile, gusimbuza hydroxypropyl, gusimbuza methyl nibindi bintu. Kugirango utezimbere amazi yo kubika ifu yuzuye, banza uhitemo icyitegererezo cya HPMC.
Ubukonje bwinshi HPMC: HPMC ifite uburemere buke bwa molekile irashobora gukora imiterere ikomeye y'urusobekerane, ifasha kunoza uburyo bwo gufata amazi yifu ya putty no kwirinda guhindagurika kwamazi hakiri kare. Mubisanzwe, HPMC ifite ubukonje bwinshi bizagira ingaruka nziza kubushobozi bwo gufata amazi.
Urwego rukwiye rwo gusimbuza: Gusimbuza hydroxypropyl no gusimbuza methyl ya HPMC bigira ingaruka ku bushobozi bwayo no kubika amazi. Urwego rwo hejuru rwo gusimbuza hydroxypropyl rufasha kuzamura hydrophilicity ya HPMC, bityo bikazamura imikorere yo gufata amazi.
Ukurikije ibisabwa byifu yifu, guhitamo icyitegererezo cyiza cya HPMC birashobora kuzamura cyane igipimo cyo gufata amazi yibicuruzwa.
2. Ongera umubare wa HPMC wongeyeho
Kugirango turusheho kunoza uburyo bwo gufata amazi yifu ya putty, umubare wa HPMC wongeyeho urashobora kwiyongera muburyo bukwiye. Mu kongera igipimo cya HPMC, ikwirakwizwa ryayo muri putty irashobora kunozwa neza kandi ubushobozi bwo gufata amazi burashobora kongerwa.
Ubwiyongere bwubwinshi bwinyongera nabwo buzatuma kwiyongera kwijimye ryifu yifu. Niyo mpamvu, birakenewe ko amazi agumana neza mugihe twirinze ubukonje bukabije kugirango bigire ingaruka kubikorwa byubwubatsi.
3. Igishushanyo mbonera cyiza
Igishushanyo mbonera cyifu ya putty igira ingaruka muburyo bwo kubika amazi. Usibye HPMC, guhitamo ibindi bice muri formula (nk'ibyuzuza, ibifunga, nibindi) bizagira ingaruka no kubika amazi ya poro.
Uburinganire nubuso bwihariye: Ingano yubunini nubuso bwihariye bwa?uwuzuza ifu ya putty izagira ingaruka kuri adsorption y'amazi. Ifu nziza hamwe nuzuza bifite ubuso bwihariye burashobora gufata neza amazi no kugabanya gutakaza amazi. Kubwibyo, guhitamo gushyira mu gaciro ingano yuzuye ni ikintu cyingenzi mugutezimbere amazi.
Guhitamo ibikoresho bya sima: Niba ifu ya putty irimo sima nibindi bikoresho, reaction ya hydration ya sima irashobora kumara amazi. Niyo mpamvu, birakenewe ko hajyaho uburyo bwo kubika amazi ya putty muguhindura igipimo cya sima nuwuzuza.
4. Kugenzura uburyo bwo kuvanga
Uburyo bwo kuvanga nabwo bugira ingaruka runaka kubigumana amazi yifu ya putty. Kuvanga neza birashobora gufasha HPMC gutatanya no kuvanga neza nibindi bikoresho kugirango wirinde itandukaniro ryo gufata amazi biterwa no kuvanga kutaringaniye.
Igihe gikwiye cyo kuvanga n'umuvuduko: Niba igihe cyo kuvanga ari gito cyane, HPMC ntishobora gushonga burundu, ibyo bizagira ingaruka kumikorere yabyo. Niba umuvuduko wo kuvanga ari mwinshi, umwuka mwinshi urashobora gutangizwa, bikagira ingaruka kumiterere yifu yifu. Kubwibyo, kugenzura neza uburyo bwo kuvanga bizafasha kunoza amazi muri rusange ifu yifu.
5. Kugenzura ubushuhe bwibidukikije nubushyuhe
Kugumana amazi yifu ya putty ntabwo bifitanye isano gusa nibikoresho fatizo na formulaire, ahubwo bifitanye isano rya bugufi nubushuhe nubushyuhe bwibidukikije. Mubidukikije bifite ubushyuhe bwinshi nubushyuhe buke, ubuhehere bwifu yifu byoroshye guhumeka, bigatuma bwuma vuba kandi bikagira ingaruka kubikorwa byubwubatsi.
Mugihe cyubwubatsi, ubushyuhe bukwiye nubushuhe bukwiye kubungabungwa bishoboka kugirango birinde ifu yimbuto gutakaza amazi vuba. Kugenzura neza ubushyuhe bw’ibidukikije n’ubushuhe birashobora kandi kunoza mu buryo butaziguye gufata amazi yifu ya putty.
6. Ongeramo ibikoresho bigumana amazi
Usibye HPMC, izindi miti igumana amazi nazo zishobora gufatwa nkaho zongewemo ifu yuzuye, nka polymers zimwe na zimwe, inzoga za polyvinyl, nibindi. Ibi bikoresho bigumana amazi birashobora kurushaho kunoza uburyo bwo gufata amazi ya putty, bikongerera igihe cyo kubaka, kandi bikarinda gushira byumye kandi bikavunika vuba.
Ariko, mugihe wongeyeho ibikoresho bigumana amazi, birakenewe kwitondera guhuza kwabo na HPMC kugirango harebwe niba nta ngaruka mbi zibaho cyangwa ngo zigire ingaruka kumyubakire ya putty.
7. Koresha tekinoroji yo kugenzura ubuhehere
Mubihe bimwe bidasanzwe, tekinoroji yo kugenzura ubushuhe irashobora gukoreshwa mugutezimbere amazi meza yifu ya putty. Kurugero, gukoresha amazi ashingiye kumazi cyangwa ibikoresho byo guhumeka birashobora kugabanya neza gutakaza amazi yibishishwa mugihe cyubwubatsi, kugumana ubushuhe bwurwego rwa putty, bityo bikongerera igihe cyo kubaka no kuzamura amazi.
Kugumana amazi yifu ya putty birashobora kunozwa neza muguhitamo ubwoko bwiza bwaHPMC, kongera umubare wongeyeho, kunonosora amata, kunoza uburyo bwo kuvanga, kugenzura ubuhehere nubushyuhe bwibidukikije byubaka, nizindi ngamba. Nkigice cyingenzi cyifu yifu, kunoza uburyo bwo gufata amazi ya HPMC ntibishobora kunoza imikorere yubwubatsi gusa, ahubwo binanoza ubwiza bwubwubatsi bwa nyuma no kugabanya inenge nibibazo byubwubatsi. Kubwibyo, gusobanukirwa no kumenya ubu buryo kugirango tunoze igipimo cyo gufata amazi ningirakamaro cyane mubikorwa bitanga umusaruro kandi ukoresha ifu yuzuye.
