Kugadzirira HydroxyPropropyl methylcellose (HPMC) Kuverenga mhinduro ndeye yakakosha maitiro mune maindasitiri emishonga uye ezvekudya. HPMC chinhu chinowanzoshandiswa polymer mukubatanidza mafomu nekuda kweiyo yakanaka firimu-inoumba midziyo, kugadzikana, uye kuwirirana nevakawanda vanoshanda zvinoshanda. Kuunganidza mhinduro kunoshandiswa kupa zviyero zvekudzivirira, kudzora kunoburitsa profita, uye kugadzirisa chitarisiko uye kushanda kwemapiritsi, macaps, uye mamwe mafomu akasimba.
1. Zvigadzirwa zvinodiwa:
Hydroxyprupyl methylcellose (HPMC)
Solvent (kazhinji mvura kana musanganiswa wemvura uye doro)
Plasticzez (inosarudzika, kugadzirisa kushanduka kweiyo firimu)
Zvimwe zvinowedzera (kusarudza, kunge verufu, epacifiers, kana anti-yekubata vamiririri)
2. Zvishandiso zvinodiwa:
Kusanganisa ngarava kana mudziyo
Mhanyisa (muchina kana magineti)
Kurera Balance
Kupisa sosi (kana zvichidikanwa)
Sieve (kana zvichidikanwa kubvisa mapundu)
ph meter (kana pH kugadzirisa kunodiwa)
Kuchengetedza Gear (Magurovhosi, GOGGLES, Lab Coat)
3. Procedure:
Nhanho 1: Kuyera zvisanganiswa
Kuyera iyo inodiwa huwandu hweHPMC uchishandisa chiyero chakaremerwa. Mari yacho inogona kusiyana zvichienderana nekuvhara kwaunoda kwemhedzisiro yekubatanidza uye saizi ye batch.
Kana uchishandisa plasticzer kana zvimwe zvekuwedzera, kuyera iyo inodiwa huwandu zvakare.
Nhanho yechipiri: Kugadzirira kweSolvent
Sarudza mhando yeiyo solvent kuti ishandiswe yakavakirwa pane iyo application uye kuwirirana neiyo inoshanda zvinoshandiswa.
Kana uchishandisa mvura sezvo solvent, simbisa kuti ndiko kuchena kwakanyanya uye zvakanyanya kuyerera kana kufananidzwa.
Kana uchishandisa musanganiswa wemvura uye nedoro, sarudza iyo yakakodzera ratio zvichienderana neiyo solubility yeHPMC uye hunhu hwaunoda mhinduro yekubatanidza.
Nhanho 3: Kusanganisa
Isa mudziyo wekusanganisa pane iyo inomoka uye wedzera iyo solvent.
Tanga kumutsa solvent pakumhanya zvine mwero.
Zvishoma nezvishoma wedzera iyo pre-yakaremerwa HPMC poda kupinda mukukurudzira solvent kuti udzivise kudzikisira.
Ramba uchimutsa kusvikira iyo HPMC poda yakaparadzirwa zvakafanana mune solvent. Maitiro aya anogona kutora imwe nguva, zvichienderana nekushambadzira kweHPMC uye kushanda kwemidziyo inosimudzira.
Nhanho 4: Kupisa (kana zvichidikanwa)
Kana iyo HPMC isinganyungudhori zvachose pamhepo tembiricha, kupisa nyoro kungave kuri madikanwa.
Pisa musanganiswa uchimutsa kusvikira iyo HPMC yakanyungudutswa zvachose. Iva akangwara kuti asanyanyisa, sekunyanyisa kupisa kunogona kushatisa hpmc kana zvimwe zvikamu zvemhinduro.
Nhanho 5: Kuwedzera kwePlasticzer uye mamwe maOndSitives (kana zvichishanda)
Kana uchishandisa plasticzezer, uwedzere kuSolution zvishoma nezvishoma uchimutsa.
Saizvozvo, wedzera chero imwe yekuwedzera inodiwa seyakafanana nevanhu kana epacifile panguva ino.
Nhanho 6: PH kugadzirisa (kana zvichidikanwa)
Tarisa iyo pH yemhedzisiro yekubatanidza uchishandisa ph metres.
Kana iyo pH iri kunze kweiyo yaunoda huwandu hwekugadzikana kana zvikonzero zvinowirirana, gadzirisa nekuwedzera zvidiki zvidiki zve acidic kana mhinduro dzechokwadi zvinoenderana.
Simudza iyo mhinduro zvakakwana mushure mekuwedzera kweumwe neumwe uye ronga iyo pH kusvikira iyo danho raunoda rinowanikwa.
Nhanho 7: Kupedzisira kusanganisa uye kuyedza
Kamwe zvinhu zvese zvikawedzerwa uye zvakanyatso kusanganiswa, ramba uchimutsa kwemamwe maminitsi mashoma kuti uve nechokwadi chekuti homogeneity.
Ita chero mikana yemhando yemhando yakaita seye viscossity kuyerwa kana kuongororwa kwekuona kune chero zviratidzo zvezvinhu zvechikamu kana chikamu chekuparadzaniswa.
Kana zvichidikanwa, pfuura iyo mhinduro kuburikidza neshungu kuti ubvise chero mapundu akasara kana zvimedu zvisingadzivisike.
Nhanho 8: Kuchengetedza uye kurongedza
Chinjana iyo yakagadzirirwa HPMC inogadzirisa mhinduro mumidziyo yakakodzera yekuchengetedza, zvirinani amber girazi mabhodhoro kana midziyo yepurasitiki yepurasitiki.
Raira midziyo yacho ine ruzivo rwakakosha senge batch nhamba, zuva rekugadzirira, kusangana, uye mamiriro ekuchengetedza.
Chengetedza mhinduro munzvimbo inotonhorera, yakaoma yakaoma yakachengetedzwa kubva muchiedza uye unyoro kuti urambe wakasimba uye urerufu hupenyu.
4. Matipi uye kufunga:
Gara uchitevedzera maitiro akanaka ekurambidza uye nhungamiro dzekuchengetedza kana uchibata makemikari nemidziyo.
Chengetedza kuchena uye shuwa mukati megadziriro yekugadzirira kudzivisa kusvibiswa.
Edza kuwirirana kwemhinduro yekubatanidza neiyo yakagadzirirwa substrate (mahwendefa, makapu) usati wakakura-chiyero application.
Bata kugadzika zvidzidzo kuti uongorore nguva refu-yekuita uye mamiriro ekuchengetedza emhedzisiro yekubatanidza.
Nyora kugadzirira maitiro uye chengetedza marekodhi ekudzora mhando zvinangwa uye kutevedzera kutevedzera.
