Hydroxypropylmethylcellulose (HPMC) ikemikari inoshandiswa zvakanyanya mumaindasitiri akati wandei. Inonyanya kushandiswa kukora uye emulsifying zvinangwa muminda yekuvaka, chikafu, zvizorwa uye mishonga. Muchikamu chino, tinokurukura mamwe matipi ekushandisa HPMC zvinobudirira mukugadzira maitiro.
1. Nzwisisa maitiro eHPMC
Usati washandisa HPMC mukugadzira maitiro, zvakakosha kuti unzwisise maitiro ayo emuviri nemakemikari. HPMC inonyanya kunyungudika mumvura uye isinganyunguriki muorganic solvents. Kana yawedzerwa kumvura, inoumba mhinduro yakajeka uye ine viscous. HPMC haina-chepfu, isiri-ionic, uye haina kuita nemamwe makemikari.
2. Sarudza giredhi rakakodzera reHPMC
HPMC inowanikwa mumagiredhi akati wandei, imwe neimwe iine maviscosities akasiyana, mamorekuru uremu uye saizi diki. Kusarudza giredhi rakakodzera zvinoenderana nerudzi rwechigadzirwa chauri kugadzira. Semuenzaniso, kana iwe uri kugadzira zvinwiwa zvitete, ungangoda yakaderera viscosity giredhi yeHPMC, uye kune zvakakora zvigadzirwa, yakakwirira viscosity giredhi. Kuonana nemugadziri weHPMC kunokurudzirwa kuti uone giredhi rakakodzera rechigadzirwa chako.
3. Iva nechokwadi chekuchengetedza mamiriro ezvinhu
HPMC is hygroscopic, zvinoreva kuti inotora hunyoro kubva mumhepo. Zvakakosha kuchengeta HPMC munzvimbo yakaoma uye inotonhorera kudzivirira kukaka kana kuomesa. Inofanirwa kuchengetwa mumidziyo isingapindi mhepo kudzivirira kusangana nemhepo kana mwando.
4. Nyatsosanganisa HPMC nezvimwe zvinhu
HPMC inonyanya kushandiswa seyakakora kana bhainda panguva yekugadzira. Izvo zvakakosha kusanganisa iyo HPMC zvakanaka pamwe nezvimwe zvinongedzo kuti uve nechokwadi chehomogeneous musanganiswa. HPMC inofanira kuwedzerwa kumvura uye kubvongodzwa zvakakwana isati yasanganiswa nezvimwe zvinhu.
5. Shandisa huwandu hwakakodzera hweHPMC
Huwandu hwakakodzera hweHPMC yekuwedzera kune chigadzirwa zvinoenderana neinodiwa yemuviri zvivakwa, viscosity uye zvimwe zvinongedzo. Kupfuura kana pasi pedosi yeHPMC inogona kukanganisa kunaka uye kugadzikana kwechigadzirwa chekupedzisira. Zvinokurudzirwa kushandisa HPMC mukati meiyo yakatarwa inokurudzirwa nemugadziri.
6. Zvishoma nezvishoma wedzera HPMC kumvura
Paunenge uchiwedzera HPMC kumvura, inofanira kuwedzerwa zvishoma nezvishoma kudzivirira kuumbwa kwezviputi. Kukurudzira nguva dzose kunodiwa kana uchiwedzera HPMC kumvura kuti uve nechokwadi chemusanganiswa unowirirana. Kuwedzera HPMC nekukurumidza kunokonzeresa kupararira kusina kuenzana, izvo zvinokanganisa chigadzirwa chekupedzisira.
7. Chengetedza pH yakakodzera
Paunenge uchishandisa HPMC, iyo pH yechigadzirwa yakakosha. HPMC ine pH shoma, pakati pe5 ne8.5, kupfuura iyo kushanda kwayo kunogona kudzikiswa kana kurasika. Kuchengeta iyo chaiyo pH level kwakakosha kana uchishanda neHPMC.
8. Sarudza tembiricha yakakodzera
Paunenge uchishandisa HPMC, tembiricha yechigadzirwa panguva yekugadzira nekuchengetedza yakakosha. Zvinhu zveHPMC, senge viscosity, solubility, uye gelation, zvinoenderana nekupisa. Iyo tembiricha yakakodzera yekusanganisa HPMC ndeye 20-45 madhigirii Celsius.
9. Tarisa kuenderana kweHPMC nezvimwe zvinoshandiswa
Hazvisi zvese zvinoshandiswa zvinoenderana neHPMC. Kuenderana kweHPMC nezvimwe zvinongedzo kunofanirwa kuongororwa usati wawedzera HPMC. Zvimwe zvinongedzo zvinogona kuderedza kushanda kweHPMC, nepo vamwe vachigona kuisimudzira.
10. Chenjerera kune mhedzisiro
Kunyangwe HPMC isiri-chepfu uye yakachengeteka kushandisa, inogona kukonzera ganda kana kutsamwa kweziso. Kuchenjerera kunofanirwa kutorwa, sekupfeka zvekudzivirira senge magirovhosi nemagirazi, uye kudzivirira kufema guruva reHPMC.
Kupfupisa, kuwedzera HPMC mukugadzira maitiro kunogona kuvandudza kunaka uye kugadzikana kwechigadzirwa. Nekudaro, kuti ushandise HPMC nemazvo, zvakakosha kutora matanho anodiwa uye kutevedzera matipi ari pamusoro.
