Hydroxypropyl methylcellulose (HPMC) is a multifunctional non-ionic cellulose ether, iyo inoshandiswa zvakanyanya munzvimbo dzakawanda dzakadai sekuvaka, mishonga, zvokudya, zvizorwa, etc. HPMC ine yakanakisa thickening, film-forming, bonding, emulsifying, kuchengetedza mvura uye kudzikamisa zvinhu. Inogona kunyungudika mumvura uye kuumba yakajeka viscous fluid, ichipa akasiyana zvigadzirwa chaiwo zvivakwa.
(1) Nzvimbo huru dzekushandisa dzeHPMC
1. Indasitiri yekuvaka
HPMC chinhu chakakosha chekuwedzera kwezvinhu zvekuvaka, chinoshandiswa kusimudzira mashandiro uye kugadzirisa mhedzisiro yekuvaka.
Putty poda: HPMC inobata basa mukukora, kuchengetedza mvura nekuvandudza zvivakwa zvekuvaka muputty powder, iyo inobatsira kuwedzera nguva yakavhurika uye kudzivirira kuputika kwenzvimbo yekuvaka.
Tile adhesive: Inovandudza kubatanidza simba uye anti-slip zvivakwa, zvichiita kuti kunamira kuve nyore kuisa.
Self-leveling pasi: HPMC inoshandiswa kugadzirisa fluidity uku ichiona yakagadzikana viscosity.
2. Indasitiri yemishonga
HPMC inowanzoshandiswa mumishonga yekugadzirira, kunyanya mapiritsi uye capsules.
Tablet binder uye firimu rekare: HPMC inoshandiswa mukuvhara firimu remapiritsi kuchengetedza zvinodhaka uye kudzora kuburitswa.
Kugadziriswa-kusunungurwa kwekugadzirira: Semumiririri wegelling, inogadzirisa kusunungurwa kwemishonga.
3. Indasitiri yezvokudya
Muchikafu, HPMC yakakosha kukora uye emulsifier, inoshandiswa mukugadzira yakaderera-makoriori chikafu kana sechinotsiva miriwo capsules.
Jelly, pudding: Inopa kuravira kwakagadzikana uye gel zvinhu.
Zvinhu zvakabikwa: Inoshandiswa kuvandudza hupfu hwehupfu uye kuwedzera hupenyu hwesherufu.
4. Zvizoro uye zvigadzirwa zvemakemikari zvemazuva ese
HPMC inoshandiswa mumafuta ekuzora, shampoos uye mushonga wemazino.
Lotions uye makirimu: Inoshandiswa seyakakora uye inodzikamisa kuti ipe kunzwa kutetepa kunopararira.
Mushonga wemazino: Inokora uye inodzivirira stratification.
(2) Mabasa makuru eHPMC
1. Kuchengeta mvura
HPMC inogona kuvandudza zvakanyanya kuchengetwa kwemvura muzvigadzirwa zvakaita sekuvaka uye chikafu, uye kudzivirira kutsemuka kana kuparara nekuda kwekurasikirwa nemvura.
2. Kukora mhedzisiro
HPMC inoumba yunifomu yakakwirira-viscosity mhinduro mushure mekunyunguduka mumvura, iyo inogona kuvandudza magadzirirwo uye kugadzikana kwechigadzirwa.
3. Firimu-kugadzira pfuma
Iyo yakanakisa firimu-yekugadzira pfuma inogona kuumba inodzivirira layer pamusoro pemishonga, machira uye zvizoro.
4. Kudzikamisa uye emulsification
HPMC inogona kunyatso kudzivirira stratification yemvura musanganiswa uye kuwedzera emulsification mhedzisiro.
(3) Maitiro ekushandisa HPMC
1. Disolution nzira
Kana HPMC yanyungudika mumvura, kutarisirwa kunofanira kutorwa kudzivirira kusangana. Matanho anotevera anokurudzirwa:
Zvishoma nezvishoma nyudza HPMC mumvura yekamuri tembiricha, uchibvongodza paunenge uchisasa kuti uparadzire zvakaenzana.
Mushure mekumira kweimwe nguva yenguva, HPMC inotora mvura uye inozvimba uye inonyungudika zvizere kugadzira mhinduro yakajeka.
2. Dosage ratio
Zvivako zvekuvaka: kazhinji 0.1% kusvika 0.5% yezvinhu zvakaoma.
Mushonga uye chikafu: Zvichienderana nezvinodiwa zvekugadzira, chiyero chiri pakati pe0.5% ne3%.
3. Kusanganisa kurongeka
Kuti ive nechokwadi chekuenderana nezvimwe zvinhu zvakabikwa, HPMC inofanirwa kuwedzerwa zvishoma nezvishoma panguva yekukurudzira kudzivirira kusangana uye kuve nechokwadi chekugovera yunifomu.
(4) Kungwarira pakushandisa
Dissolution tembiricha:HPMC inonyungudika zvakanyanya mumvura patembiricha yemumba, asi inonzwa zvakanyanya kumvura inopisa uye inofanirwa kudzivirira yakanyanya kunyungudika tembiricha.
Mamiriro ekuchengetera: HPMC inofanirwa kuchengetwa munzvimbo yakaoma, ine mhepo, kure nekunyorova kana zuva rakananga.
Kugarisana kwezvakatipoteredza: HPMC inoodza, haina chepfu uye haina kukuvadza panguva yekushandiswa, uye yakachengeteka kumuviri wemunhu uye nharaunda.
Nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari, hydroxypropyl methylcellulose inoshandiswa zvakanyanya mumaindasitiri mazhinji. Kubva pazvivakwa zvekuvaka kusvika pakugadzira chikafu kusvika pakugadzirira mishonga, HPMC yakaita basa rinokosha. Mukushandiswa chaiko, iyo dosi uye nzira yekushandisa inofanirwa kugadziridzwa zvinoenderana nechaicho chigadzirwa chinodiwa uye kuita zvinodiwa kuti ipe kutamba kwakazara mukubudirira kweHPMC uye nekupa vimbiso yekuita kwechigadzirwa uye ruzivo rwemushandisi.
