Hydroxypropyl methylcellulose (HPMC)ni imvange ya polymer ikunze gushonga mu mazi, ikoreshwa cyane mu miti, ibiribwa, ibikoresho by'ubwubatsi, amavuta yo kwisiga n'ibindi bikorwa. HPMC ifite ubushobozi bwo gushonga no gushonga neza kandi ishobora gukora umuti uhamye wa colloidal, bityo igira uruhare runini mu bikorwa byinshi. Kugira ngo HPMC ikore neza, uburyo bwo gushonga bukwiye ni ingenzi cyane.
1. Uburyo bwo gushonga amazi mu bushyuhe busanzwe
HPMC ishobora gushonga mu mazi akonje, ariko ubusanzwe hakenewe ubuhanga bumwe na bumwe kugira ngo hirindwe kwivanga kwayo. Kugira ngo kunoze ingaruka zo gushonga, intambwe zikurikira zishobora gukoreshwa:
Intambwe ya 1: Shyira HPMC mu mazi
Ku bushyuhe bw'icyumba, banza usuke HPMC ku mazi neza kugira ngo wirinde ko HPMC nyinshi isuka mu mazi icyarimwe. Kubera ko HPMC ari polymer, kongeramo HPMC nyinshi mu buryo butaziguye bizatuma ifata amazi kandi ibyimbe vuba mu mazi kugira ngo ikore ikintu gisa na gel.
Intambwe ya 2: Gukangura
Nyuma yo kongeramo HPMC, komeza uvange neza. Kubera ko HPMC ifite uduce duto, izabyimba nyuma yo kwinjiza amazi kugira ngo ikore ikintu gisa na gel. Kuvanga bifasha kwirinda ko HPMC yivanga mu duce duto.
Intambwe ya 3: Hagarara wongere uvange
Iyo HPMC itarashonga burundu, umuti ushobora gusigara uhagaze akanya gato hanyuma ugakomeza kuvanga. Ubusanzwe uzashonga burundu mu masaha make.
Ubu buryo burakwiriye mu bihe aho gushyushya bidakenewe, ariko bifata igihe kirekire kugira ngo HPMC ishonge burundu.
2. Uburyo bwo gushonga amazi ashyushye
HPMC ishonga vuba mu mazi ashyushye, bityo gushyushya ubushyuhe bw'amazi bishobora kwihutisha cyane inzira yo gusenya. Ubushyuhe busanzwe bukoreshwa mu gushyushya amazi ni 50-70°C, ariko ubushyuhe bwinshi cyane (nk'ubushyuhe burenze 80°C) bushobora gutuma HPMC igabanuka, bityo ubushyuhe bugomba kugenzurwa.
Intambwe ya 1: Gushyushya amazi
Shyushya amazi kugeza kuri dogere 50°C kandi ukomeze kuyakoresha uko yakabaye.
Intambwe ya 2: Ongeraho HPMC
Suka HPMC buhoro buhoro mu mazi ashyushye. Bitewe n'ubushyuhe bwinshi bw'amazi, HPMC izashonga byoroshye, bigabanye ukwivanga kw'amazi.
Intambwe ya 3: Gukangura
Nyuma yo kongeramo HPMC, komeza kuvanga amazi. Guhuza ubushyuhe no kuvanga bishobora gutuma HPMC ishonga vuba.
Intambwe ya 4: Komeza ubushyuhe kandi ukomeze kuvanga
Ushobora kugumana ubushyuhe runaka no gukomeza kuvanga kugeza igihe HPMC ishongeshejwe burundu.
3. Uburyo bwo gushonga inzoga
HPMC ishobora gushonga atari mu mazi gusa, ahubwo no mu bintu bimwe na bimwe bya alukolo (nk'ethanol). Akamaro gakomeye k'uburyo bwo gushonga alukolo ni uko bushobora kunoza uburyo HPMC ishonga n'uburyo ikwirakwiramo, cyane cyane ku buryo amazi menshi arimo.
Intambwe ya 1: Hitamo umuti ukwiye wo gushonga alcool
Ibikoresho by'inzoga nka ethanol na isopropanol bikunze gukoreshwa mu gushonga HPMC. Muri rusange, umuti wa ethanol uri hagati ya 70-90% ugira ingaruka nziza mu gushonga HPMC.
Intambwe ya 2: Gusenyuka
Suka buhoro buhoro HPMC mu cyungo cy’ubunyobwa gikozwe muri alcool, ubyuke wongereho kugira ngo HPMC ikwirakwizwe neza.
Intambwe ya 3: Guhagarara no gukangura
Uburyo bwo gushonga alcool HPMC bwihuta cyane, kandi akenshi bifata iminota mike kugira ngo ishonge neza.
Uburyo bwo gushonga inzoga bukunze gukoreshwa mu gihe bisaba gushonga vuba no kugabanya amazi.
4. Uburyo bwo gushonga buvanze n'amazi
Hari igihe HPMC ishongeshwa mu ruvange rw'amazi n'umushongi runaka. Ubu buryo bukwiriye cyane cyane mu bihe aho ubushyuhe bw'umushongi cyangwa igipimo cyo gushonga gikeneye guhindurwa. Imishongi isanzwe irimo acetone, ethanol, nibindi.
Intambwe ya 1: Tegura igisubizo
Hitamo igipimo gikwiye cy'umushongi n'amazi (urugero: 50% by'amazi, 50% by'umushongi) hanyuma ushyushye kugeza ku bushyuhe bukwiye.
Intambwe ya 2: Ongeraho HPMC
Mu gihe uvangavanga, ongeramo HPMC buhoro buhoro kugira ngo urebe ko byashonga neza.
Intambwe ya 3: Guhindura byinshi
Uko bikenewe, igipimo cy'amazi cyangwa solvent gishobora kongerwa kugira ngo hakosorwe uburyo HPMC ishonga n'uburyo ishonga.
Ubu buryo burakwiriye mu bihe aho imiti mvaruganda yongerwamo imiti y’amazi kugira ngo yongere umuvuduko wo gushonga cyangwa ihindure imiterere y’imiti.
5. Uburyo bwo gusenya hakoreshejwe Ultrasonic
Hakoreshejwe uburyo bwa ultrasound bukoresha ikoranabuhanga rigezweho, uburyo bwo gushonga bufashijwe na ultrasound bushobora kwihutisha inzira yo gushonga kwa HPMC. Ubu buryo bukwiriye cyane cyane ingano nini ya HPMC igomba gushonga vuba, kandi bushobora kugabanya ikibazo cyo gushonga gishobora kubaho mu gihe cyo gukangura bisanzwe.
Intambwe ya 1: Tegura igisubizo
Shyiramo HPMC ku gipimo gikwiye cy'amazi cyangwa umuti uvanze n'amazi.
Intambwe ya 2: Ubuvuzi bwa Ultrasonic
Koresha imashini isukura icyuma gipima ikirere cyangwa imashini ipima ikirere (ultrasonic) hanyuma uyikoreshe ukurikije imbaraga n'igihe byagenwe. Ingaruka zo guhindagurika kwa ultrasound zishobora kwihutisha cyane inzira yo gusenya HPMC.
Intambwe ya 3: Reba ingaruka zo gusenyuka
Nyuma yo kuvurwa hakoreshejwe ikoranabuhanga, reba niba umuti washongeshejwe burundu. Niba hari igice kitashongeshejwe, kuvurwa hakoreshejwe ikoranabuhanga bishobora kongera gukorwa.
Ubu buryo bukwiriye gukoreshwa mu buryo busaba gusenywa neza kandi vuba.
6. Kuvura mbere yo gusenyuka
Kugira ngo wirindeHPMCGuhuza cyangwa kugorana gushonga, hari uburyo bumwe na bumwe bwo kuvura mbere y’uko bivangwa, nko kuvanga HPMC n’ibindi bintu bike bivangwa (nka glycerol), kubanza kuyumisha, cyangwa kuvomesha HPMC mbere yo kongeramo ibintu bivangwa. Izi ntambwe zo kuvura mbere y’uko bivangwa zishobora kunoza uburyo HPMC ishonga neza.
Hari uburyo bwinshi bwo gushonga HPMC. Guhitamo uburyo bukwiye bwo gushonga bishobora kunoza cyane imikorere myiza yo gushonga no kunoza ubwiza bw'ibicuruzwa. Uburyo bwo gushonga ubushyuhe bw'icyumba bukwiriye ahantu hakonje, uburyo bwo gushonga amazi ashyushye bushobora kwihutisha inzira yo gushonga, kandi uburyo bwo gushonga alcool hamwe n'uburyo bwo gushonga amazi avanze birakwiriye gushonga bitewe n'ibikenewe byihariye. Uburyo bwo gushonga bufashijwe na ultrasound ni uburyo bwiza bwo gukemura ikibazo cyo gushonga vuba kw'ingano nini ya HPMC. Dukurikije ibisabwa byihariye byo gukoresha, guhitamo uburyo bwo gushonga bukwiye bishobora kwemeza ko HPMC ikora neza mu nzego zitandukanye.
